Rebuild the per-entry emission instrument as a .dag entry point: DESIGN's declared restoration trigger for the bankrupted board by briansrls · Pull Request #9190 · gunb-ai/gunbc

briansrls · 2026-08-25T13:19:07Z

DESIGN's Building-&-checks section carries a declared rung drop titled THE MEASUREMENT BANKRUPTCY DELETED A CAPABILITY, NOT ONLY ARTIFACTS. It names its own restoration trigger: a .dag entry point that emits, assembles and compiles one entry and returns the coded-diagnostic population, cited by name wherever a board figure is quoted. This is that entry point. It is the instrument, not a board — it produces the numbers and stores none of them.

gunbc run --source-root dag --source-root src/v2 \
  --entry dag/tools/emission_entry_instrument.dag --function measure \
  --arg entry=<repo-relative .dag path> --arg report=<path>

What lands

tools.emission_entry_instrument — runs the spine the deleted probe script ran: gunbc compile --entry → cssl_assemble → cargo under --message-format=json. It returns EmissionMeasurement, a coproduct built around three distinctions, each of which closes a way a measurement can lie:

Which phase was reached. "Refused before the emitter ran" has no spelling in the same shape as "emitted with zero diagnostics" — an unreached stage is its own variant naming the stage. FilesNotWritten is distinct from FilesEmitted { count: 0 }. A compiler that ran and refused is a completed measurement of the emit phase; an instrument that could not run is not.
What produced it. Every outcome carrying a population also carries an EmissionMeasurementSubject — entry, source revision, working-tree standing, and the sha256 of the two binaries actually invoked — established before the emitter runs. A component that cannot be observed refuses the run rather than being recorded as absent: an unobserved digest is not the digest of nothing. The one arm without a subject is the one that took no measurement, so an unattributable population has no representation. Vocabulary is reused, never re-coined: CommitSha from extdeps.git.inspect, Digest from extdeps.crypto.hash.
Whether the population is the whole population. v1.05_emit_rust emit_rust is a sequence of early returns — measured on the live file, two arms return EmitResult { files: [], diagnostics } before the rest of the body runs, so while the first fires the checks after it never execute. A count over emit can therefore be a prefix of the truth. Both early returns write no files and the CLI prints compiled: only where a tree was written, so the extent is derived exactly: a compile that reported emitted files ran the body to its end; one that reported none is EmitPopulationCompletenessUnestablished. The count and its extent are rendered by one expression, so a number never travels without the standing of the set it counted.

extdeps.cargo_diagnostic — the rustc coded-diagnostic population. A population, not a total: identity (E-code, or the named uncoded state — an uncoded diagnostic is a member, not an absence) and location (primary span, selected by is_primary, never by position) per finding, so two runs can be joined rather than only differenced. An unreadable line, an empty stream, and a stream with no build-finished message each refuse with a located cause. That last one matters: cargo closes every run it performed with a terminal message, so a stream that parses cleanly and simply stops is a killed run's prefix — reporting it would be the truncated-observation-as-complete failure that created this lane, reproduced inside the instrument built to end it. The terminal message's success is also the authority on whether the build was clean, replacing a transport exit status observed beside the stream. It is a sibling of extdeps.cargo_message rather than a widening of it, which that module's own boundary note asks for, and shares its line framing.

gunbc.emit_diagnostic_observation — the emit-stage population, decoded from what the CLI already prints. No v1 capability is added: emission is 05_emit territory and the seed is frozen with maintenance active, so this consumes the existing surface rather than widening the seed for an instrument's convenience. A prose decode that skips what it does not recognise would be an absorbing fallback; what makes it admissible is that the compiler states its own total twice — the compiled: line and the renderer's severity summary — and a recovered population disagreeing with either, or the two disagreeing with each other, refuses and names both numbers.

extdeps.tools.sha256sum gains one operation, DigestFile. CheckFile answers "does this file match this digest", which cannot be used to learn one.

What is NOT claimed

Not a gate. No workflow invokes it, no phase enrols it, nothing here blocks a merge. Its exit status reports whether the instrument completed, never whether the subject was clean: an entry with a thousand diagnostics is a successful measurement, and an instrument that could not run exits nonzero having found nothing wrong with anything.

Not a second whole-compile path. The whole-corpus route stays refused by gunbc.whole_corpus_compile_admission; this is the per-entry route that module's own scope note says fits.

The DESIGN row is amended in its authority (gunbc.design_document), not retired: the trigger has fired, and every other clause of the bankruptcy stands — including that a figure copied into prose is debt whether or not a producer exists for it.

Tests / evidence

Executed, not described. Each claim below went green by running it:

gunbc run --claim-run --entry dag/test/claim/emission_entry_instrument_witness_test.dag --function <name> — PASS on the cargo population claim, the primary-span-by-flag claim, the uncoded-member claim, and the discriminating reds: an unreadable line, an empty stream, a stream with no terminal message, an emit population smaller than the compiler's own total, the compiler's two totals disagreeing, and a summary-less compile. Plus the carrier claims: an unreached stage and a zero-diagnostic measurement are different values that render differently; a measurement names the compiler that produced it; an unestablished subject carries neither provenance nor population; a refused emit's population is never reported as complete while a completed one is.
Entry compile of the instrument itself: 0 blocking, re-run green after each correction.
The discriminating subject, re-derived here rather than carried from the dispatch brief: dag/extdeps/cpu/ampere.dag at c271b75829 refuses at emit with 9 blocking / 119 advisory, and the emit decoder's rules recover exactly 128 located members against that real output — the cross-check doing its job on production text, not on a fixture.
Rust suite / clippy are not run in CI on this repository by standing operator ruling; this PR adds no Rust.

Per the standing rule, no figure above is a standing number: each names the run that produced it, and the point of the PR is that there is now an instrument to name instead.

DESIGN's Building-&-checks section carries a declared rung drop titled THE MEASUREMENT BANKRUPTCY DELETED A CAPABILITY, NOT ONLY ARTIFACTS. It states its own restoration trigger: a .dag entry point that emits, assembles and compiles one entry and returns the coded-diagnostic population. This is that entry point. It is the INSTRUMENT, not a board -- it produces numbers and stores none. tools.emission_entry_instrument measure_entry_emission runs the spine the deleted probe script ran (gunbc compile --entry -> cssl_assemble -> cargo under --message-format=json) and returns EmissionMeasurement, in which "refused before the emitter ran" has no spelling in the same shape as "emitted with zero diagnostics": an unreached stage is its own variant naming the stage. That is DESIGN's execution-provenance-loss row applied to the instrument that most needed it. extdeps.cargo_diagnostic decodes the rustc coded-diagnostic population -- one member per finding, identity (E-code or the named uncoded state) and location (the primary span, selected by is_primary rather than by position), so two runs can be joined rather than only differenced. A line it cannot read, and an empty stream, refuse with a located cause instead of reporting an empty population. It is a sibling of extdeps.cargo_message rather than a widening of it, which that module's own boundary note asks for. gunbc.emit_diagnostic_observation decodes the emit-stage population from what the CLI already prints. No v1 capability is added: emission is 05_emit territory and the seed is frozen with maintenance active, so this reads the existing surface rather than widening the seed for an instrument's convenience. What makes a prose decode admissible is the cross-check -- the compiler states its own total on the `compiled:` line and again in the renderer's severity summary, and a population disagreeing with either, or the two disagreeing with each other, refuses and names both numbers. NOT A GATE. No workflow invokes it, no phase enrols it, and the exit status reports whether the INSTRUMENT completed, never whether the subject was clean. Evidence: witness claims carry greens and discriminating reds for both decoders and for the carrier's own distinction. Measured at c271b75: the entry compile of the instrument itself is 0 blocking / 138 files emitted, and dag/extdeps/cpu/ampere.dag refuses at emit with 9 blocking / 119 advisory -- re-derived here, not carried from a brief.

Two corrections from review on #9190, both narrowing. ONE -- THE CARRIER NAMED ITS STAGES AND NOT ITS COMPILER. Splitting the phase states is state-space de-conflation; it is not provenance, and the prose claimed provenance. DESIGN separates the two deliberately: conflation is repaired by splitting states, execution-provenance loss by BINDING A RECEIPT to the value. Without one, the carrier could report the same-looking population from two different compilers -- the same defect one level down from the one the stage split closes. Every outcome that carries a population now carries an EmissionMeasurementSubject: entry, source revision, working-tree standing, and the sha256 of the two binaries actually invoked. It is established BEFORE the emitter runs, and a component that cannot be observed refuses the run rather than being recorded as absent -- an unobserved digest is not the digest of nothing. The one arm without a subject, EmissionSubjectUnestablished, is the one that took no measurement, so an unattributable population has no representation. The identity vocabulary is REUSED, not re-coined: CommitSha from extdeps.git.inspect, Digest from extdeps.crypto.hash. Minting a parallel identity vocabulary inside the instrument built to enforce single authority would be the violation it exists to measure. extdeps.tools.sha256sum gains one operation, DigestFile: CheckFile answers "does this file match this digest", which cannot be used to LEARN one. TWO -- A KILLED BUILD'S PREFIX READ AS A POPULATION. The decoder returned a population from any nonempty parseable prefix, so cargo emitting seventeen messages and then being SIGKILLed reported those seventeen as the answer. That is the truncated-observation-rendered-as-complete failure that created this lane, reproduced inside the instrument built to end it. cargo closes every run it performed with build-finished; a stream without one now refuses and says how far it got. Its `success` member is also now the authority on whether the build was clean, replacing the transport exit status observed beside the stream -- the terminal message is emitted BY the run being measured. Executed: PASS on the truncated-stream red, the terminal-message verdict in both polarities, and both provenance claims (a measurement names its compiler; an unestablished subject carries neither provenance nor population), with an existing green re-run as a regression control. Entry compile of the instrument after both corrections: 0 blocking, 145 files emitted. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Reviewed both corrections against the diff. Both landed, neither widened anything, and one of them you took further than I asked in a way I want to endorse explicitly.

SUBJECT BINDING IS RIGHT, AND THE UNESTABLISHED ARM IS THE PART THAT MAKES IT REAL. EmissionMeasurementSubject carries entry, source_revision: CommitSha, working_tree, compiler: Digest, assembler: Digest, assembly_mode. But the load-bearing move is EmissionSubjectUnestablished { entry, stage, cause } carrying NO population at all. That is what makes an unattributable measurement structurally impossible rather than merely discouraged — there is no way to spell a population without the subject that produced it. Establishing the subject BEFORE the emitter runs, and refusing when a component cannot be observed rather than recording it absent, is the same rule stated at the right end: an unobserved digest is not the digest of nothing.

working_tree_standing_text rendering dirty as 'the measured bytes are not the revision's bytes' is the correct honesty. A CommitSha on a dirty tree names a revision the measurement did not take, and saying so in the rendering means a reader cannot quietly treat the two as the same.

THE THING YOU DID THAT I DID NOT ASK FOR, AND WHICH IS BETTER THAN WHAT I ASKED FOR. I said require build-finished. You made its success member the AUTHORITY on whether the build was clean, replacing the transport exit status you had been reading beside the stream. That is the sharper form of the same argument and I should have stated it that way: the terminal message is emitted BY the run being measured, whereas an exit status is a fact about a process someone observed nearby. Those are different subjects, and preferring the one the measured run itself emits is exactly the provenance rule applied one level in. The refusal text — that a prefix without build-finished would be 'a killed process's partial output rendered as a finished measurement' — names the failure that created this lane.

The empty-stream refusal is equally well-aimed: a build that ran emits at least a terminal message, so an empty stream means the invocation was swallowed, never started, or read from the wrong field. Reporting that as a clean build is precisely the fabricated zero. Three different not-a-population states, three different causes, none collapsed onto each other.

VOCABULARY REUSE CHECKED, not taken. CommitSha from extdeps.git.inspect, Digest from extdeps.crypto.hash. The one addition is an OPERATION rather than a type, and it is justified on the strongest possible grounds: sha256sum carried only CheckFile, which answers does-this-file-match-a-digest-I-already-have and therefore structurally cannot be used to LEARN one. DigestFile beside it, cited to the same coreutils authority, is a genuine gap in the modeled surface rather than a convenience. That is the right distinction — adding an operation the upstream tool really has is modeling; adding a type that duplicates one is nicknaming.

ON WHAT YOU DECLINED TO CARRY: I agree, and I am glad you named it rather than omitting it silently. The emitted candidate tree and installed mirror digests answer 'which TREES were involved', and the question this instrument exists to answer is 'which COMPILER produced this population' — which the two binary digests settle. A directory-wide walk per run to answer a question no consumer has asked is cost with no displaced pain. Add them when something needs to join across trees, not before.

No changes requested. When you flip it out of draft I will look at the witness set as a whole, but the two corrections are closed as far as I am concerned.

One thing for your calibration, since it bears on what your instrument will see: I now have srv1 access (502 GB available against the 7.52 GB admission demand) and a whole-corpus emit is running there on a clean worktree at main 4f080fd. That does not change your task — a whole-corpus run on one large machine is not a substitute for a per-entry route that works on the default runner, which is the routing inversion whole_corpus_compile_observed_kill_receipt_note already documents. If anything it gives your instrument a cross-check.

Requirement from smart-ram-730, relayed from deep-ant-102's finding, and it is a level finer than the phase split already in the carrier. THE FINDING, verified here by reading the emitter rather than taken on report: v1.05_emit_rust emit_rust is a sequence of early returns. Measured on the live file there are exactly two, both `return EmitResult { files: [], diagnostics }`, and while the first fires the checks after it NEVER EXECUTE -- two workflow-parameter diagnostics were observed masking eight anonymous-record ones, which had been standing the whole time. So any count taken over emit can be a PREFIX of the truth rather than the truth: not an undercount anyone can bound, but a count that stops silently at whichever earlier check fired. WHY THE EXISTING ARMS DID NOT COVER IT. They distinguish WHICH PHASE the instrument reached. This is finer: within one EmissionMeasured, emit itself may have returned before a later check ran, so two results that both honestly report "emit ran" can differ in whether a check even executed. A consumer reading the first concludes the entry has two blocking diagnostics; it has at least ten. THE DERIVATION IS EXACT, not a guess, which is what makes this a construction rather than a warning. Both early returns write NO FILES, and the CLI prints its `compiled:` line only where a tree was written. So a compile reporting emitted files ran the emit body to its end and its population is Complete; one reporting none is CompletenessUnestablished. That second arm is named for IGNORANCE rather than truncation on purpose: a refusal caused outside emit also lands there, and claiming such a population IS truncated would answer a question this observation cannot answer. Over-stating ignorance is safe; the opposite is the defect. AND THE COUNT NEVER TRAVELS ALONE. The size and the extent are rendered by ONE expression, so a report stating a population size always states the standing of the set it counted -- a separate optional row would let the number travel by itself, which is the entire failure. Executed: PASS on a refused population never reported as complete, a completed one reported as complete (so the extent is a real discriminator and not a constant), no report stating a population without its extent, and the existing carrier claim re-run as a regression control. Entry compile: 0 blocking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

REVIEW (manager, smart-ram-730) — one finding that is not about the diff, and that I think changes what this PR should include. Not a request to abandon anything: the instrument is the right construction and DESIGN names it as the restoration trigger verbatim. The finding is about what it stands on.

gunbc compile --entry IS NOT MODELLED IN THE .dag AUTHORITY. It exists only in the one declared divergence.

Measured, symbolically, not from a line offset:

src/v1/05_emit_rust.dag, the Compile variant render: the field list ends at dependency_pool_index: String, followed immediately by the closing "},". No entry field is rendered. The Commands::Compile { ... } destructuring it emits is likewise { source_roots, source_dir, output_dir, target, dependency_pool_index } — five bindings, no entry.
Nine lines later in the SAME function, the Run variant render carries entry: Option<String>,. So the authority models --entry for run and does not model it for compile. The asymmetry is in one function, which is what makes it a clean read rather than an inference across files.
src/v1/stage0/src/main.rs DOES have it — Commands::Compile destructures entry, with a doc comment describing exactly the subtree-scoping this instrument needs.
And main.rs is this repository^s ONE declared divergence from its emitted form: required-regen reports declared_divergent=1 [main.rs].

So the flag this instrument^s entire spine rests on lives exclusively on the hand-maintained side of the only sanctioned drift in the tree.

WHY THAT MATTERS HERE SPECIFICALLY, AND NOT MERELY IN GENERAL. The instrument exists to measure how self-emission is progressing. Its first step shells out to a CLI surface that self-emission cannot produce. On the day the CLI is emitted from its .dag authority — which is the event this instrument is built to watch — compile --entry stops existing and the instrument stops running. It is an emission-convergence gauge wired to the one surface that convergence deletes. That is not a latent risk; it is the success condition of the program this measures.

CORROBORATING SYMPTOM, found before I understood the cause, which is why I trust it. Both installed binaries reject the flag outright: mine (Aug 23) and snappy-dove-250^s (Aug 25 03:04) both answer error: unexpected argument --entry found on gunbc compile. I spent real time concluding a falsifier was blocked on a stale binary. The actual shape is narrower and worse: --entry is recent, hand-added, and present only where regen is permitted not to look.

WHAT I AM ASKING FOR — one field, and it shrinks the divergence rather than growing anything. Render entry: Option<String> on the Compile variant in src/v1/05_emit_rust.dag alongside its destructuring, exactly as Run already does nine lines up. The pattern to copy is in the same function, so this is not new design. Two things follow: the instrument then stands on the model instead of the drift, and main.rs^s declared divergence gets one item smaller — the direction §7 wants it moving.

I would take that in THIS PR rather than a follow-up, because the instrument^s value is precisely that it keeps working across the transition it measures, and shipping it against the divergence means its first real test is the thing that breaks it.

NOT CLAIMED: that the divergence is illegitimate. main.rs has a sanctioned, declared divergence and I am not reopening that. I am claiming this one field does not need to be in it, and that this instrument is the reason to move it now.

…ulation `gunbc compile --entry` is NOT MODELLED in the .dag authority. Verified on the live file: v1.05_emit_rust emit_subcommand_enum renders the Compile variant with five fields and no `entry`, while the Run variant nine lines below carries `entry: Option<String>`. The flag exists only in the hand-maintained main.rs, this repository's one declared divergence from its emitted form. TWO HAZARDS, FAILING IN OPPOSITE DIRECTIONS, and only the second is dangerous. A compiler WITHOUT the flag refuses the invocation outright -- loud, and already safe through this decoder. A compiler that ACCEPTS the flag and IGNORES IT compiles the whole first source root and prints an ordinary summary, which a per-entry instrument reads as one entry's population: a silent whole-tree substitution reported as a per-entry measurement. THAT SECOND STATE IS NOT HYPOTHETICAL -- it is what closing the divergence naively would produce. The same function that renders the variant also renders the HANDLER, and the handler is the whole-tree implementation; its own emitted comment reads "Entry modules: all .dag files in the FIRST source root", with no entry dispatch anywhere in it. So rendering the field without its handler would REMOVE A WORKING LOUD REFUSAL and replace it with a plausible wrong answer. That change is therefore not made here, and the reason is recorded so the next author does not re-derive it from the variant alone. THE FIX IS ON THE INSTRUMENT SIDE AND NEEDS NO v1 CHANGE. The compiler names the scope it used -- a reference-derived closure for the entry path, an import closure for the whole-tree path -- so the decoder now requires that marker before it will read any population and refuses EmitScopeUnconfirmed otherwise. A population read without knowing which scope produced it is stage-did-not-run rendered as stage-ran-with-this-result, at the producer boundary. Also recorded, in the carrier rather than in a message: the subject's `entry` is a PATH because the actuation surface takes one and offers no identity-keyed alternative, so a rename reads as a different subject. A consumer keying by declaration identity owns that mapping and must treat it as able to go stale. Executed: PASS on the whole-tree scope line as the red and the real entry-scoped line as the green -- so the guard is a discriminator and not a constant -- with two prior greens re-run as regression controls. Entry compile: 0 blocking, 145 files emitted. The missing-arm refusal the closed vocabulary raised while wiring this is itself the exhaustiveness wall working.

….crypto.hash owns review 55859, REQUEST_CHANGES. sha256sum.dag re-minted sha256_algorithm_authority pointing at FIPS 180-4, forking the citation owned by extdeps.crypto.hash extdeps_external_authority_anchor. review 50411 had already refused the identical fork in the sibling sha512sum, whose note records the consume rule. THE FORK HAD ALREADY DRIFTED, which is why it is deleted rather than reconciled: the local row read .../180-4/final, the owning row reads .../180-4/upd1/final. Two spellings of one citation had begun to disagree about which revision of the standard is cited -- the decay 3 predicts, and the reason a second name for one fact is a correctness concern and not a style one. PROVENANCE, STATED BECAUSE IT CHANGES WHO OWES WHAT: the forked row is PRE-EXISTING ON MAIN, not introduced by #9190 -- that PR added DigestFile and the Digest-typed read only. This is debt the stack touched rather than authored. It is cleared here anyway: it is a real fork with a documented precedent refusing it, and provenance is not a defence for leaving one standing. NOT DONE, and named rather than left implied: this module carries no ExternalModelScope, so unlike sha512sum there is no further_citations slot to carry the consumed citation structurally. Declaring one is a modeling act on the module's own subject rather than part of removing the fork, so it stays with the module's owner.

… second summary line Both found by review 55852 over gentle-bee-495's stacked PR 9213, relayed rather than edited across lanes. Both legitimate, and both are the exact failure this instrument was built to end, committed inside the instrument. ONE -- cargo_diagnostic_bool_value answered `false` for every non-boolean shape of is_primary. A MALFORMED flag and a well-formed `false` reached one answer, so an unreadable flag routed its span to "not primary" and, where no other element claimed primacy, the whole diagnostic reported RustcSpanAbsent: a located finding losing its location with no diagnostic. That is ⊤-as-ignorance rendered as an answer, in the one decoder whose every sibling arm refuses -- and the file already SAID so: the comment over span_member_or_null reads "every caller above treats JsonNull as unreadable rather than as a value", which this function did not. It now returns Bool? and an unreadable flag refuses. It also undercut a claim I had already made. the_primary_span_is_selected_by_ its_flag_not_by_position asserts the flag is load-bearing; a flag that cannot be read silently fell back to position-independent absence instead of stopping. TWO -- emit_summary_fold answered with the LAST matching line, so two `compiled:` lines in one stream discarded the first without a diagnostic. Fixed as a typed refusal naming which anchor duplicated and how many times. THE SEVERITY FOLD HAD THE IDENTICAL DEFECT and the review named only the compiled one; fixing the named half alone would have left the same silent overwrite one fold away. The anchor is a closed pair (CompiledSummaryAnchor | SeveritySummaryAnchor), not a string, so a third anchor cannot be reported without every reader refusing to compile until it decides what the new one means. EXECUTED, 7/7: the malformed-flag refusal AND its control -- a well-formed `is_primary: false` still reading as an unlocated finding -- because a decode that simply refused every span would pass the refusal and mean nothing. Both duplicate-anchor refusals, each asserting which anchor and a count of 2. Three prior greens re-run as regression controls. Entry compile 0 blocking.

…er's evidence while tidying a sentence Three findings from the thread review, verified against the code before acting. THE SCOPE MARKER WAS MINE TO LOSE AND I LOST IT. Main prints "resolved N sources (reference-derived closure), M indexed modules"; consolidating the two CLI pipelines into one generic line dropped the parenthetical. It existed at the merge-base, so this is a regression on this branch and not a collision. `gunbc.emit_diagnostic_observation` `emit_entry_scope_marker` (landed on main via #9190, AFTER my change) matches that exact text and returns `EmitScopeUnconfirmed` when it is absent -- specifically so a whole-root compile cannot be reported as one entry's measurement. Merging main unchanged would have made every per-entry emission measurement refuse, from an edit that reads as prose cleanup. RESTORED AS A VALUE, NOT AN ADJECTIVE. `CompileScopeReceipt` is derived from `CompileSubject`, so the receipt cannot disagree with the run and cannot be lost by rewording. The entry arm carries the marker; the primary-root arm now STATES what it measured instead of being silent, so a consumer no longer has to infer scope from argv or file counts. The Rust literal and the `.dag` `data` row are two spellings of one fact -- unavoidable while that authority is `.dag` and this seed cannot read it -- so the constant is named `EMIT_ENTRY_SCOPE_MARKER` and cites its authority, making the pair greppable. THE TEST ASSERTS BOTH HALVES. Marker present on the entry arm, ABSENT on the primary-root arm. A receipt that carried it on both would be worse than one that carried it on neither: the marker exists to make the substitution refusable. THE PANICKING TRAVERSAL. My earlier "typed refusal" fixed the per-FILE read and left the DIRECTORY walk calling `collect_dag_files`, which is `collect_dag_files_result(..).unwrap_or_else(|e| panic!(..))`. A missing root, a regular file as root, or any `read_dir` failure bypassed `CompileDisposition` entirely. That was half a repair wearing the whole one's name; the walk is fallible now. TARGET ADMISSION ORDERING, PROVEN RATHER THAN ASSERTED. The new arm passes a subject that CANNOT be discovered, so if the duplicate-target refusal came after subject discovery the run would refuse at `entry-read` instead and the arm would fail. It proves the ordering, not merely the refusal. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc

…ugh the grammar (#9242) * Split the required run into two parallel jobs, and correct the ruling the split supersedes The required run's four phases are mutually independent and were also SERIAL, because one process runs them one after another. That is the expensive combination: the witness floor costs ~30-40 minutes and every other phase waited behind it for no reason a data dependency names, so the required check's wall clock was a SUM of things that could have been a MAX. Operator ruling 2026-08-25 ("we can add it as a parallel job in github actions - we can do the same for regen now, we have more runners" / "basically i would put regen + v2 full compile in one job, and witnesses into another one"). Two jobs, no `needs` edge: build regen first-generation comparison + the v2 emission compile witnesses the .dag parse sweep + the witness floor fold Each job makes ONE invocation of claim_executor and names a LANE. It does not name phases, order them, or wire one phase's precondition to another step's outcome -- which phases a lane owns is `RequiredCiPhase::lane`, an exhaustive match, so a phase belonging to no job fails to compile rather than going silently unmeasured. Every run prints a ROUTED line for each phase it does not own, so one job's log names the whole roster and where the rest is measured. THE 2026-08-20 CONSOLIDATION DIRECTIVE IS CORRECTED, NOT SILENTLY CONTRADICTED. It has two halves and only one is superseded. SURVIVES -- "within the gunbc binary": the phases still live in the binary and the step-ladder defect the consolidation fixed cannot return. SUPERSEDED -- "not at a github actions job level": parallelism is not expressible in one process, so the lane boundary is a job boundary of necessity, and what the directive protected against (sequencing and preconditions leaking into YAML) is exactly what does not cross it. Both halves are now stated in DESIGN's CI clause, in `gunbc.fabric_witness_run`, in `gunbc.witness_floor_workflow` and in the consolidation witness file. THE v2-EMISSION SUBJECT WIDENED in the same change, from `dag/std/abi.dag` to `src/v2/compiler/00_compile.dag`. The cost that argued for the smallest entry was a cost against a SERIAL run; the build lane's cost is now free up to the floor's duration. Measured by emitting both closures and differencing the file sets, the widening gives up exactly one file of coverage, `src/std_abi.rs`, and the row says so rather than claiming total subsumption. Executed evidence: - both lanes run, and route correctly: `lane=witnesses` runs parse and floor and routes regen and v2-emission; `lane=build` runs regen and v2-emission and routes parse and floor - an unknown lane word refuses with exit 2, it does not default - the v2 compiler entry compiles clean under the phase's own producer and pinned pool index (0 blocking) - six consolidation witnesses pass, including two new ones for the split - both new REDs flip under mutation and restore: adding a `needs` edge reds the parallel claim; collapsing to one job reds the two-lane claim - the lane-command claims verified through a scratch probe with a control that returns false NOT DONE, named rather than absorbed: no ratchet over the v2 compile's advisory population (a count pinned to the current tree is the oracle DESIGN §5 rejects; the honest form is an identity-grain monotone debt contract, a separate construction). Nothing else is restored from the deleted floor machinery. And the build step still compiles only the two bins the jobs run -- a declared `[[bin]]` outside that set is uncovered, with a live specimen on main today (`infer_semantics_witness`, six E0063s); widening to `--bins` changes what the required check covers and is an operator decision, so it is declared here rather than taken.

That paragraph sits directly above the run step the split changed, so it is the one a reader reaches first, and leaving it standing would be the premise contamination this change exists to remove -- one document corrected while its own subject still recited the superseded ruling in the present tense. It now states both halves: 'within the gunbc binary' survives, 'not at a github actions job level' is superseded because parallelism is not expressible in one process. The step-ladder paragraphs below it are kept rather than rewritten, because what they establish is unchanged by the split and deleting them would take the reasoning with them. Also corrected: the step no longer passes 'the source roots and nothing else' (it passes a lane word), and the phase roster is four across two lanes rather than the 2026-08-21 three.

Verified against the live ruleset rather than against the workflow, which is the only place the fact is visible: `passing CI` is active, carries NO bypass actors, and names exactly ONE required status check -- `witnesses`. A GitHub required context is produced by the JOB, not the workflow, so moving regen and v2-emission into a second job made them NON-BLOCKING: the required check would go green over a regen drift or a v2 emission break and the PR would be mergeable. That is strictly worse than the serial run it replaced, because the serial job carried every phase into the one context that gates. THE REPAIR, and why it is an aggregation job rather than a ruleset edit. The floor lane is renamed `floor`; the name `witnesses` moves to a job whose only step reads both lanes' results and exits nonzero unless both succeeded. The two lane jobs still carry no `needs` edge on each other and still start together -- only the aggregator waits, and it does nothing but read two results. A ruleset edit would also have worked and was rejected on a boundary DESIGN already records: the ruleset is not a `.dag` fact, so landing a change whose safety depends on someone editing a setting afterwards is a coverage gap with a promise attached and a real window in which the lane is unguarded. `if: always()` IS LOAD-BEARING, and its absence would have been the same fail-open one level in: a step with no `if` inherits `success()`, so it would be SKIPPED exactly when a lane failed, the job would report success, and a skipped required check does not stop a merge. The aggregator is the only place in this workflow that authors shell text, and that is stated on the carrier: there is no modeled value to render, because GitHub has no declarative "this job fails unless those jobs succeeded", and the nearest declarative form is the skip that fails open. The script is built from the job-id declarations rather than spelling `needs.build.result`, so a rename moves both sides together instead of rendering an unknown context as the empty string. WITNESS CORRECTION, not just an addition. `w_RED_neither_lane_waits_on_the_other` asserted the file contained no `needs:` at all -- the right claim for a workflow shape that was wrong, and a row that would have made this repair unrepresentable. It now forbids each single-lane edge and REQUIRES the aggregator's two-lane one, which distinguishes the serialization being forbidden from the aggregation being demanded. A third row asserts the gate runs and refuses. Executed evidence: all seven consolidation witnesses pass, and three mutations red the right rows and restore -- serializing floor onto build reds the parallel claim, dropping `always()` reds the gate claim, and deleting the aggregator reds the parallel claim.

A job that declares `needs` and no `if` is SKIPPED when any needed job fails, is skipped, or is cancelled. A skipped job never starts, so it never reaches its steps, so the step-level `always()` could not fire -- and a skipped required check does not stop a merge. The aggregator introduced to close the fail-open would have gone skipped-and-mergeable over precisely the failed lane it was there to catch, with the guard present in the file and reading as correct. `always()` AT JOB LEVEL, AND THIS IS THE ONE PLACE THAT DEPARTS FROM THE FILE'S `!cancelled()` HOUSE GUARD -- said in the carrier, in DESIGN and in the witness, because a reader who knows the convention will otherwise correct it back and reopen the hole. Every other guard here decides whether a STEP runs inside a job that is already running, where `!cancelled()` is right. This one decides whether the REQUIRED CONTEXT EXISTS AT ALL, and under `!cancelled()` a cancelled run leaves it skipped rather than answered. That would turn the outcome on a question about GitHub nobody here has executed -- does a skipped or cancelled required check block a merge -- and the response is not to go measure it but to make the answer not matter. Under `always()` the job always runs, always reads both results, and always reports on its own terms; SKIPPED disappears from the required context. Cost, named: a lawfully superseded run now reports this context red rather than cancelled. That is the correct reading, not a regression -- a superseded run's evidence must not admit a merge. THE WITNESS WAS WRONG IN THE SAME WAY AND IS FIXED WITH IT. It asserted `if: always()` appeared SOMEWHERE in the file. It did -- on the step -- so it went green over the defect. That is DESIGN's total-at-the-level-examined failure: true, and about the wrong level. It now discriminates on emitted INDENTATION, which is the only thing in the text that separates the two levels (a job key at four spaces, a step key at eight), and asserts both. Executed: the strengthened row PASSES on the fix and FAILS on a mutation that removes the job-level guard -- i.e. it catches the exact defect that shipped. All seven consolidation witnesses pass.

Measuring against that ask showed this PR's own prose overclaims, so the claim is corrected before anything is built on it. MEASURED, by emitting the entry and joining the emitted file names against the module line of every src/v2/compiler/**.dag: of the 42 modules under src/v2/compiler/, 00_compile's closure emits 24. Eighteen are absent, including ingest, emit_module, emit_host, emit_produced, emit_semantic_decl, program_partition and self_host. Counting the self_host/ subtree the compiler namespace is 69 modules, so the shortfall is larger again. "The widest closure one entry names" was true and is kept; "full v2 compile" invites the reading that the phase covers the compiler, and it does not. That reading is exactly the premise contamination this repository keeps paying for, so the row now states the covered population rather than leaving a reader to assume it. AND A METHOD NOTE THAT COST A MEASUREMENT: a static import-closure estimate CANNOT substitute here. It reports ZERO compiler coverage for this entry, because this corpus resolves most cross-module references without import lines. Only the compiler's own reference-derived closure is the truth, which means a covering entry set cannot be derived from the import graph either -- it has to be measured by emission. The widening itself is NOT taken here: it needs either a measured covering entry set or a whole-tree emission whose cost has to be known before it is enrolled in a required lane. This row makes that widening a change to a known number instead of an assumed one.

The aggregator ran anyway under its job-level always(), read the two results, refused, and published the required context witnesses as a FAILURE. That is this gate's first executing receipt and it is the behaviour the pre-repair shape could not produce -- there, the aggregator would have been skipped. AND THE RUN SURFACED A needs RESULT VALUE NOBODY HERE KNEW WAS REACHABLE: BUILD="cancelled" FLOOR="abandoned" The gate handles 'abandoned' correctly only because it compares != "success" rather than enumerating bad states. The form a reader's instinct reaches for -- == "failure" || == "cancelled" -- would have admitted it and reported the required context GREEN over two lanes that never ran. So the strict inequality is now recorded on the carrier as a measured fact rather than left as a style choice, because the obvious 'improvement' to an explicit list is a fail-open. That is the difference between a closed vocabulary and a remembered one: the inequality admits exactly one state and refuses every other, including the ones the author has never heard of.

That ambiguity cost that session hours in one day, diagnosing 38 lawful supersessions as a false-red epidemic. The file's house guard really is !cancelled() everywhere else. It is not taken, and the reason is an asymmetry about WHICH HEAD PAYS. Checks are tracked per head SHA, so a superseded run's red lands on a head that by construction is never merged -- the push that superseded it created the head that will be. always() is noisy on ABANDONED heads. !cancelled() moves the cost onto the LIVE one: a lane killed with no replacement run coming, observed twice on 2026-08-25 (once with runner_name empty and zero steps, once with both lanes ended at 18:43 and no push involved), leaves the required context SKIPPED on the head that is still the merge candidate -- which is precisely the unmeasured GitHub behaviour the guard exists to stop depending on. Quiet-and-unknown on a live head is worse than loud-and-definite on a dead one. The mechanism half of the objection is now MEASURED rather than documented: run 32883390033 had both lanes ended by a fleet event, and this job published failure while the run conclusion was cancelled. So the behaviour the objection predicts is real; what is disputed is only whether it is the wrong trade. Recorded in the carrier rather than answered away, so the next person who wants !cancelled() finds the case already made instead of rediscovering it. Comment-only in emission terms: witnesses.yml regenerates byte-identical. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * One compilation transaction, subject-parameterized; the gate emitted as nodes Four things, in the order the operator's dispatch puts them. ONE. The build lane bootstraps `cargo build --release -p v1-compiler --bins`. Host-Rust coverage of the whole declared bin roster is a fact somebody has to establish, and a bin no consumer selects is precisely the one that rots unobserved -- #9205 repaired one such bin after it had drifted with nothing building it. The floor lane keeps the two bins it executes; the lanes are runtime-independent, so their bootstraps are independent CPU rather than a shared prerequisite one could save. TWO. THE DAGLANG COMPILATION FORK IS CLOSED. `cli_run` now carries `CompileSubject{Entry|PrimaryRoot}`, `CompileRequest` and `compile_emission`, and the transaction owns indexing and precedence, subject source-set construction, census fill, memory admission, resolution and compilation, the blocking/advisory split, silent-pick capture and the disposition. `compile_entry_emission` survives as a wrapper with no semantics of its own. Before this, `gunbc compile` without `--entry` implemented a SECOND index/load/resolve/admit/compile/refuse pipeline in `main.rs`, beside the transaction rather than through it. They differed in ways nobody had decided: the whole-root arm applied the memory-admission gate and the entry arm did not, the entry arm ran the silent-pick gate inside the transaction and the whole-root arm ran it around the outside, and their refusal subjects were spelled differently. That is DESIGN section 3's two-authorities-for-one-fact, and it is the reason a whole-tree ratchet could not be built on the existing phase: the ratchet would have observed a different producer from the gate beside it. The arms' real differences are KEPT, which is why this is a coproduct and not a flag: admission is asked of the whole root and not of an entry (an entry's working set is its closure, measured to fit on the runner that SIGKILLed a whole-tree run -- an unasked question, not an all-clear), and the closure derivation genuinely differs (reference-derived for an entry, import-edge for a root where every module is already an entry). A `PrimaryRoot` matching no module refuses at `subject-discovery` rather than reporting `Completed { 0 }`, which would be the empty-observation narrow. THE DELETION WAS THE CENSUS. Routing the whole-root subject through the transaction left ~200 lines in `main.rs` with no caller, and rustc then found seven more private copies of module indexing and import walking -- `extract_module_path`, `report_moduleless_dag_entry_skips`, `extract_import_paths`, `insert_module_path`, `index_source_root`, `build_module_index`, `resolve_transitively_with_seen`. All deleted; their two tests re-pointed at the surviving `cli_run` authority rather than retired with the function, per DESIGN section 4b(4). Multi-target (`--target a,b`) still walks the old loop and is named rather than exempted. THREE. `pr_owner` AND `cycle_owner` REFUSED FOR A REASON THAT IS NOT IN `review_codex.dag`. `owner` has TWO declarations in the flat whole-tree namespace -- `data owner` in `gunbc.tools.review_codex` and `fn owner(uid, gid)` in a srv3 path-ownership test -- and the winner is fold order. When the function won, the CLI defaults resolved to it and refused with `must be a string, int, float, bool literal, or data reference`: two blocking diagnostics in a file that had not changed, produced by a test helper in another directory. The discriminating pair is what establishes that, and it was measured rather than reasoned. `repo` is declared beside `owner` in the same module, has no `fn repo` anywhere in the corpus, and does not refuse. `default_model` IS declared twice -- `tools.review` and `tools.review_codex` -- and does not refuse either, because both declarations are data, so either winner satisfies the default's requirement. Collision alone is not the fault; collision ACROSS DECLARATION KINDS is. Fixed by renaming the test helper to `owner_spec`. The class is untouched and the annotation says so: a bare cross-kind homonym is still writable and still resolves by fold order. Its next-rung trigger is a refusal at name resolution when one flat name carries declarations of different kinds -- decidable from the index the compiler already builds -- not a roster of forbidden names. FOUR. THE REQUIRED-LANES GATE IS BUILT AS NODES, NOT SPELLED AS TEXT. `gunbc.required_lanes_gate` constructs it through `v2.extdeps.languages.bash_build` and `witness_floor_workflow` serializes it through `v2.workflow.bash_command_fold_serialize` -- the `tools.build_step` -> `v2.workflow.build_step_emit` precedent. Raised as review 55836's medium-as-string finding, which was correct: I had argued no modeled value existed to render, and the language was fully modeled the whole time. Declaring a language-layer gap without enumerating the language is the failure DESIGN records in its own section 6 receipt. The Rejected arm REFUSES rather than rendering nothing, because an empty `run` exits 0 and would make the required context green over two lanes it never read. The emitted text was executed against all three arms: success/success passes, success/failure and cancelled/abandoned each print the error and exit 1. ALSO LANDED, NOT YET WIRED: `gunbc.v2_rustc_debt` models the monotone identity ledger -- key (emitted-crate-relative path, rustc code), admission iff observed equals the current ledger AND the current ledger is a multiplicity-wise subset of the baseline's -- with eleven fixture arms that author both input and expectation. Both totals are receipt-only and reach no verdict. Its host observation is deliberately absent: an observer built before a whole-tree emission can be produced would be an observer with no subject. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * The subject is a field, the precedence root is a refusal, and the fork is three callers wide FOUR CORRECTIONS, three of them from an operator ruling on the measured report and one from the census that ruling asked for. ONE. THE ALIAS DIRECTION WAS BACKWARDS. It read `pub type CompileRun = EntryEmissionRun`, which makes the generic name an alias of the entry-named authority -- so the canonical carrier stays the one named for a subject it no longer describes, and every reader is sent to a type whose name contradicts two of its three uses. `CompileRun` and `CompileDisposition` are now the types; the entry-named spellings are the compatibility aliases that disappear with their last caller. TWO. `run.entry` SILENTLY WIDENED TO HOLD A DIRECTORY. A consumer reading it after a `PrimaryRoot` compile got a root from a field promising a file -- one name, two meanings, which is the section 3 violation the fork closure exists to remove, reintroduced one field down. It is now `subject: CompileSubject`, and the receipt names the ARM rather than the path: `subject=primary-root:src/v2`, not `subject=src/v2`. The two read identically to a human and differently to anyone deciding whether a run measured what it was asked for, which is the whole reason the field exists. THREE. THE SUBJECT AND THE PRECEDENCE ROOT NOW HAVE TO AGREE, AND DISAGREEING REFUSES. The trap is entirely in argv order and invisible from the receipt: the live workflow passes `--source-root dag --source-root src/v2`, and the no-entry CLI law is `PrimaryRoot(source_roots[0])`, so THAT argv asks for `PrimaryRoot(dag)` with `src/v2` as a pool. A caller who means "compile v2" and writes the roots in the workflow's habitual order gets the other subject, compiles ~2000 different modules, and is told the compile completed. This is not a scope difference, it is a RESOLUTION difference, and it already cost a measurement: `dag`-primary refuses on two `review_codex` CLI defaults that `src/v2`-primary never reaches, and `src/v2`-primary refuses on 36 diagnostics `dag`-primary never sees. The 9.06 GiB peak and the `owner` diagnostics reported earlier are the `dag` subject; they were reported under a heading that implied the v2 one. A ledger bootstrapped from the wrong subject is not a coarser ledger, it is a ledger about another population. `primary_root_agrees_with_precedence` makes the disagreement unwritable rather than merely detectable. FOUR. THE FORK IS THREE PRODUCTION CALLERS WIDE, NOT ONE. The census over `compile_sources`, `compile_sources_with_options`, `compile_to_resolved_with_options`, `emit_resolved_for_target` and `stage0_self_compile_refusal_message` classifies every caller: 46 compiler_tests / compiler_tests_rust kernel test, legitimate 2 v1_probe_emit_interp generated kernel probe, legitimate 2 v1_compiler_emit_rust compiler implementation, legitimate 9 cli_run compile_emission implementation 5 main.rs DECLARED VIOLATION (multi-target loop) 2 required_regen_host DECLARED VIOLATION (needs ExactSourceSet) 2 bin/bootstrap_witness DECLARED VIOLATION (not previously named) `bootstrap_witness.rs` compiles EVERY `.dag` file under `dag/` to Rust, which is exactly the invariant's subject -- a repository source population producing an artifact tree -- so it is a production route and not a kernel probe. It carries its own `build_module_index`, `build_module_index_for_roots` and `resolve_imports_transitively`: a FOURTH private copy of the machinery this branch deleted from `main.rs`, in a 1289-line binary the floor lane builds and runs. It can disagree with the transaction about what the `dag/` population IS, and nothing would say so. None of the three violations is closed here. They are named, classified, and ordered: multi-target into the request as a target set, then regen and bootstrap_witness through an exact-source-set subject, both of which select a population by their own authority rather than by directory.

Only module-item grain is modeled, so strict preparation refused and the build lane went red on #9242. Hoisted above the declaration. An awk brace-depth census over every file this branch touches confirms no in-body annotation remains. Module-less visibility: the deletion note in `main.rs` claimed the module-less-entry skip report was "the one behaviour with no counterpart" in `cli_run`. That was FALSE -- `report_moduleless_dag_entry_skips` and `moduleless_dag_entry_paths` are both `pub` there with tests, and were never deleted. The note asserted an absence without grepping for it, which is the one claim a later reader will not re-check. The behaviour is now wired into the transaction's `PrimaryRoot` arm through those same two functions. It matters there specifically: the subject is discovered from `index.source_files`, keyed by module path, so a `.dag` under the root with no `module` declaration is absent from the subject and the transaction would report `Completed` over a population that silently excluded it. The empty-root refusal cannot catch this, because a root holding one good file and one forgotten one is not empty. It REPORTS rather than refuses, declared as the weaker arm: a module-less `.dag` is a legitimate parse fixture today, so refusing would break real callers. Terminal form is a total role classification under which an unclassified `.dag` refuses.

MULTI-TARGET REGRESSION (blocking). `--source-root X --target rust+dag` fell past the routing gate -- which conjoined the subject with `render_targets.len() == 1` -- into a branch whose only remaining subject is `--source-dir`, and exited "provide --source-root or --source-dir" over an argv that provided one. `CompileRequest` now carries a target VECTOR: resolve once, emit per target, and materialize NOTHING until every target has completed, so one target's tree is never left on disk beside another's refusal. The disposition, the blocking count and the refusal are over the whole emission set, not the first target. Single-target callers -- every required one -- run the identical computation, because `compile_sources_with_options` IS `emit_resolved_for_target ∘ compile_to_resolved_with_options`. Two discriminating arms: two targets produce two named emissions from one resolution, and a request naming NO target refuses at its own `target-admission` phase rather than reporting `Completed { emitted_count: 0 }`. DEBT LEDGER FAIL-OPEN (blocking). Positivity and uniqueness were asked of the LEDGER only. A duplicated key in the OBSERVATION makes the multiplicity lookup answer with whichever row the fold reaches first, so the comparison silently compares the wrong quantity and the run reads as held. All three populations are now validated -- positivity, uniqueness, and strictly ascending canonical order -- through one `DebtPopulationMalformed { population, cause, keys }`, with `population` a closed coproduct because the three have different owners and different repairs. Order refuses rather than sorts: sorting would make two textually different ledgers compare equal and stop a ledger diff being reviewable. THE BLIND-SPOT FIXTURE AUTHORED NO SUBSTITUTION. It passed `one_error()` on both sides and CLAIMED in prose that the two were different errors, which made it a tautology wearing a substitution's name. It now authors `SyntheticRustcDiagnostic` values carrying a latent site, asserts FIRST that the two populations differ, and then that bucketization erases the difference. NO BOOLEAN COLLAPSE OF THE VERDICT (review 55911). `rustc_debt_verdict_admits` matched every variant and returned one bit, so a consumer refusing on it prints "the ratchet refused" and the author re-derives the cause by hand. Deleted. Every test arm now asserts WHICH verdict, which is strictly stronger: an arm authored to provoke `LedgerExceedsBaseline` used to stay green when the contract refused it as malformed for an unrelated reason. VOCABULARY. `admitted_multiplicity` -> `multiplicity`; `identities` -> `buckets`, in the model, the receipt and the test names -- the count is per (path, code) bucket and calling it an identity is the inflation the blind-spot arm exists to deny. RENAME FINISHED. The entry-named aliases are deleted, not merely re-pointed; two spellings for one type is the same §3 violation one layer out. Also: the census behind "one compilation concept" is now stated at CALL-SITE grain with its forks named, the `CompileSubject` comment no longer calls the import walk "the authority" (it under-pulls by construction -- the namespace is flat -- and the census fill covers the difference), the precedence check declares its rung and its terminal `SourcePool` form, and a `TypeEnv` field missing at one test site is filled so `cargo test --lib` builds at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Build the unrenderable-gate refusal from the Bash grammar too, and split the unwired debt model out of this PR Review 55923, both findings, neither deflected. THE RAW SHELL FALLBACK IS DISSOLVED, NOT MARKED. `required_lanes_gate_unrenderable_script` was an executable program spelled as a String and handed to a RunStep -- the medium-as-string violation this PR otherwise removes, surviving in the one arm nobody reads, inside the module whose own header argues against exactly that. The refusal is now Nodes in `gunbc.required_lanes_gate`, beside the gate it stands in for, serialized through the same fold. The outcome is three-state rather than two, and the third state is what removes the last fabricated value: the gate serializes -> the gate; the gate rejects but the refusal serializes -> the refusal, which stops every run loudly; both reject -> Absent, and `expected_witness_floor_yml` returns `WitnessFloorGenerationRefused` so no yaml exists at all. A Rejected fold can no longer reach a published step. The one remaining `""` is not a program and is reachable only when emission has already refused -- Daglang is total, so some value must inhabit the arm; what matters is that it is not a second spelling of a shell program and that no emission path reaches it. Verified rather than asserted: `required_lanes_gate_is_renderable` returns true by execution, and regen exits 0 with the workflow yaml BYTE-IDENTICAL -- only the unreachable arm moved. ON THE "on-carrier bash-emission scaffold marker": no such convention exists in this tree. A whole-tree search finds no `bash_emission`, `hand_shell` or `model_vs_runner` carrier. Removing the raw string makes the marker moot either way, which is the stronger repair. THE DEBT MODEL LEAVES THIS PR. `dag/gunbc/v2_rustc_debt.dag` and its fixture are removed and travel to the change that lands their consumer. The earlier review from the same provider offered keeping this PR open as the integration vehicle and I took that; a measurement since has changed the calculus. A whole-repo emission REFUSES ON MEMORY ADMISSION on the current runner class -- measured on BuildBuddy: budget 6.58 GiB against the modeled 7.00 GiB demand, `WholeCorpusCompileBudgetBelowMeasuredDemand`, zero files emitted. So the observer cannot be built until the resource-grant boundary is decided, and that decision is the operator's. Holding a foundational compilation PR open behind someone else's decision is worse than either option the review named. What remains here is the compilation consolidation and the gate repair: coherent, with consumers, mergeable on its own.

And the fork census omitted a fork Two remarks from the side-channel review, both verified against the code, both real. THE (NAME, TARGET) PAIR IS COLLAPSED TO A TARGET. `CompileRequest.render_targets` carried `Vec<(String, RenderTarget)>`, so `("dag", RenderTarget::Rust)` was constructible: two spellings of one fact, free to disagree, with the NAME deciding which directory a target is written to while the TARGET decided the bytes written into it. That is the §3 violation this transaction exists to remove, reintroduced one field down and in the same PR that removes it elsewhere. The name is now DERIVED through `render_target_name`, which is the CLI parse's inverse, so the disagreement has no representation rather than being checked for. `parse_render_targets` discards the authored spelling deliberately, because it is recoverable. THE CALL-SITE CENSUS OMITTED `required_regen_host`. `compile_stage0` calls `compile_sources` directly over `regen_input_sources` -- a fourth fork, and the census whose entire purpose is to enumerate forks reported it as absent. The file appeared in the file-level count I ran and did not survive into the call-site list I wrote from it, which is the incomplete-enumeration class this repository has recorded against itself twice before: a list transcribed from a wider measurement is not the measurement. It is now listed with its subject (an EXACT SOURCE SET from the regen roster -- neither a root nor an entry, so neither existing subject describes it), its terminal form, and the hardcoded refusal subject it still passes. The omission is recorded in the census itself rather than quietly corrected, because a census that has been wrong once should say so. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * The refusal arm the PR defends was the wrong shape, and nothing executed could have caught it Review 55928, plus four findings from the thread review that survive at this head. THE MIDDLE RUNG WAS DEAD. `required_lanes_gate_unrenderable_stmts` was declared `-> List<Node>` and returned `bash_build_stmt_list_from_nodes(...)`, which is a single `Node`. Its caller passes it as `stmts: List<Node>`. So the arm this PR argues must stay executable -- gate rejects, the refusal still serializes, the run stops loudly -- was the wrong shape in exactly the place the argument is about, while the in-file receipt said it was Nodes through the same fold. Returns the raw list now, like `required_lanes_gate_stmts` beside it. THE REASON IT WAS POSSIBLE IS THE REAL REPAIR: the claim lived in prose, so nothing could contradict it. `the_unrenderable_gate_refusal_serializes_and_stops_the_line` now runs the fold over the refusal and reads the program back -- it must serialize, and must carry both the `::error::` annotation the operator sees and the `exit 1` that stops the line. THE CONTROL FLIPS, MEASURED RATHER THAN ASSUMED. Fixed shape: true. Defect restored: `PatternMatchFailure`, the fold choking on a Node where the list belonged. ONE HONEST QUALIFICATION: the red arrives as a RUNTIME ERROR, not a returned false, which is a weaker red than a clean false -- an erroring probe stops rather than asserting anything about its subject. Recorded because "the control flips" alone would overstate it. DUPLICATE TARGETS REFUSED. `--target rust+rust` parses to two targets, and each emission's directory is derived from the target, so both land in `output_dir/rust` -- the second overwriting the first while the run reports two completions. Refused at `target-admission`, not deduplicated: collapsing it silently answers a request nobody made and destroys the signal that the argv is wrong. THE MODULE-LESS WALK NO LONGER DROPS READ FAILURES. `if let Ok(content)` narrowed "every `.dag` under the root" to "every READABLE one" while still reporting under the wider name -- the empty-observation narrow inside the population whose entire job is to report what got dropped from the subject. Now a typed refusal at a `subject-read` phase. DOCUMENTATION THAT LIED. The root-order ruling sat immediately above `names_at_least_one_target`, so Rust attached the precedence contract to target admission; moved. "One entry, one render target" and "One entry's emission transaction" corrected beside code that handles two subjects and a target vector. The alias note's history example read `pub type CompileRun = CompileRun`, which is not a direction. And "reference derivation is not used here and that is not an oversight" sat directly above the fixpoint call that falsifies it -- it is used, because an import edge is weaker than a reference in a flat namespace and the walk under-pulls across the pool boundary. Regen exits 0 with no artifact drift. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Restore the entry-scope marker as a typed receipt: I deleted a consumer's evidence while tidying a sentence Three findings from the thread review, verified against the code before acting. THE SCOPE MARKER WAS MINE TO LOSE AND I LOST IT. Main prints "resolved N sources (reference-derived closure), M indexed modules"; consolidating the two CLI pipelines into one generic line dropped the parenthetical. It existed at the merge-base, so this is a regression on this branch and not a collision. `gunbc.emit_diagnostic_observation` `emit_entry_scope_marker` (landed on main via #9190, AFTER my change) matches that exact text and returns `EmitScopeUnconfirmed` when it is absent -- specifically so a whole-root compile cannot be reported as one entry's measurement. Merging main unchanged would have made every per-entry emission measurement refuse, from an edit that reads as prose cleanup. RESTORED AS A VALUE, NOT AN ADJECTIVE. `CompileScopeReceipt` is derived from `CompileSubject`, so the receipt cannot disagree with the run and cannot be lost by rewording. The entry arm carries the marker; the primary-root arm now STATES what it measured instead of being silent, so a consumer no longer has to infer scope from argv or file counts. The Rust literal and the `.dag` `data` row are two spellings of one fact -- unavoidable while that authority is `.dag` and this seed cannot read it -- so the constant is named `EMIT_ENTRY_SCOPE_MARKER` and cites its authority, making the pair greppable. THE TEST ASSERTS BOTH HALVES. Marker present on the entry arm, ABSENT on the primary-root arm. A receipt that carried it on both would be worse than one that carried it on neither: the marker exists to make the substitution refusable. THE PANICKING TRAVERSAL. My earlier "typed refusal" fixed the per-FILE read and left the DIRECTORY walk calling `collect_dag_files`, which is `collect_dag_files_result(..).unwrap_or_else(|e| panic!(..))`. A missing root, a regular file as root, or any `read_dir` failure bypassed `CompileDisposition` entirely. That was half a repair wearing the whole one's name; the walk is fallible now. TARGET ADMISSION ORDERING, PROVEN RATHER THAN ASSERTED. The new arm passes a subject that CANNOT be discovered, so if the duplicate-target refusal came after subject discovery the run would refuse at `entry-read` instead and the arm would fail. It proves the ordering, not merely the refusal. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * The all-or-nothing materialization proof, with a RED that is actually authorable The CLI writes a tree only after the AGGREGATE disposition is `Completed`, so one target's refusal must withhold another target's finished files. That claim was asserted by the arm's structure and by nothing executable. BEFORE WRITING THE TEST I CHECKED WHETHER ITS RED CAN BE PRODUCED AT ALL, because a check whose red is unauthorable is a decoration -- permanently green by construction and worse than absent, since it gets cited as coverage (DESIGN §4b). It can: `file_emission_refusal` applies `target_renders_file_transport` FIRST and separately from `file_binding_refusal`, and that gate answers `Rust => true` with Python, Go and Dag all false. So a WELL-FORMED file-transport operation emits clean on Rust and refuses `FileTargetNotModeled` on Go. MEASURED on the new fixture root before any assertion was authored: `--target rust` emits 7 files with 0 diagnostics; `--target go` refuses, naming target 'go' and the missing file realization handler. The fixture is deliberately well-formed -- renderable path, product output shape, only modeled channels -- because a fixture with a real defect would refuse on BOTH targets and the test would pass for the wrong reason. Also measured, and it corrects the assumption I would have coded against: ordinary modules complete on every target (rust 6 files, go 3, dag 1, python 3, zero diagnostics each), so the refusal genuinely has to come from the transport gate rather than from picking an "unsupported" target. The test carries a single-target control (rust alone completes with a non-empty tree, so a future change that breaks the fixture cannot leave the test quietly asserting nothing), pins the refusal to the target-gate cause rather than any refusal, and asserts the refused run still holds the SAME file count the control emitted -- unwritten. That last assertion is the whole content: it distinguishes "the arm withheld a finished tree" from "there was nothing to write", and without it the property is vacuous. Also collapses `authored_import_names`, which the merge from main left specified THREE times in one `#[cfg(test)]` struct literal, breaking the entire lib-test target. A clean merge with no conflict, and no gate could see it: CI builds the binary and the Rust suite left CI on 2026-07-11. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * The five transaction tests were unexecutable as written; they now execute, 5 passed The PR body said these arms were "type-checked only". That was too kind to them. They were not merely unexecuted -- they were UNEXECUTABLE: a test binary's cwd is the PACKAGE root while the fixtures live at the repo root, so every one of them panicked in `index_source_root_into_module_index` with `source root does not exist` before reaching a single assertion. Discovered by running the new atomic-materialization test, not by reading. FIRST FIX WAS WRONG AND THE WRONGNESS IS THE POINT. `set_current_dir(workspace_root())` looks correct and greened four of five. It is a race: cwd is process-global and cargo runs these tests in parallel, so a DIFFERENT PAIR failed on each run -- 4 passed/1 failed, then 3 passed/ 2 failed, with identical code. A flaky green here would have been worse than the original failure because it would have read as proof. Replaced with absolute paths derived from `workspace_root()`, which has no shared mutable state to race on. Also reads the `Refused` arm rather than routing it through `cause_of`, which destructures `NotExecuted` only. The first draft panicked on its own success: the run WAS `Refused { phase: "emit", cause: "... target 'go' ... transport emission is not modeled" }`, which is exactly what the test asserts. MEASURED: `cargo test --lib -p v1-compiler` over the five, remote: 5 passed, 0 failed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Assert the withheld tree BYTE FOR BYTE, not by file count The atomicity test compared the refused run's rust emission to the control by `files.len()`. That is weaker than the property the test exists to establish: a refusal that silently substituted DIFFERENT bytes at an equal count would have passed, and "the refusal also changed the output" is exactly the failure the all-or-nothing claim rules out. The control now captures (path, content) for every rust file and the refused run is compared against it verbatim. Raised by review rather than found here, and conceded rather than argued -- an equal-count assertion is not a cheaper version of the right one, it is a different and weaker claim. MEASURED after the change, remote: 5 passed, 0 failed over the five transaction tests. UNCHANGED AND STILL DECLARED: this proves the TRANSACTION refuses while holding a complete tree. It does not observe the filesystem, because `write_output_files` lives in main.rs -- an edit moving it back inside the target loop would still pass. The test's own comment and the PR body both say so.

…, where an unmeasured subject is neither clean nor suspect (#9213) * Rebuild the per-entry emission instrument as a .dag entry point DESIGN's Building-&-checks section carries a declared rung drop titled THE MEASUREMENT BANKRUPTCY DELETED A CAPABILITY, NOT ONLY ARTIFACTS. It states its own restoration trigger: a .dag entry point that emits, assembles and compiles one entry and returns the coded-diagnostic population. This is that entry point. It is the INSTRUMENT, not a board -- it produces numbers and stores none. tools.emission_entry_instrument measure_entry_emission runs the spine the deleted probe script ran (gunbc compile --entry -> cssl_assemble -> cargo under --message-format=json) and returns EmissionMeasurement, in which "refused before the emitter ran" has no spelling in the same shape as "emitted with zero diagnostics": an unreached stage is its own variant naming the stage. That is DESIGN's execution-provenance-loss row applied to the instrument that most needed it. extdeps.cargo_diagnostic decodes the rustc coded-diagnostic population -- one member per finding, identity (E-code or the named uncoded state) and location (the primary span, selected by is_primary rather than by position), so two runs can be joined rather than only differenced. A line it cannot read, and an empty stream, refuse with a located cause instead of reporting an empty population. It is a sibling of extdeps.cargo_message rather than a widening of it, which that module's own boundary note asks for. gunbc.emit_diagnostic_observation decodes the emit-stage population from what the CLI already prints. No v1 capability is added: emission is 05_emit territory and the seed is frozen with maintenance active, so this reads the existing surface rather than widening the seed for an instrument's convenience. What makes a prose decode admissible is the cross-check -- the compiler states its own total on the `compiled:` line and again in the renderer's severity summary, and a population disagreeing with either, or the two disagreeing with each other, refuses and names both numbers. NOT A GATE. No workflow invokes it, no phase enrols it, and the exit status reports whether the INSTRUMENT completed, never whether the subject was clean. Evidence: witness claims carry greens and discriminating reds for both decoders and for the carrier's own distinction. Measured at c271b75: the entry compile of the instrument itself is 0 blocking / 138 files emitted, and dag/extdeps/cpu/ampere.dag refuses at emit with 9 blocking / 119 advisory -- re-derived here, not carried from a brief. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Bind the execution subject, and require cargo's terminal message Two corrections from review on #9190, both narrowing. ONE -- THE CARRIER NAMED ITS STAGES AND NOT ITS COMPILER. Splitting the phase states is state-space de-conflation; it is not provenance, and the prose claimed provenance. DESIGN separates the two deliberately: conflation is repaired by splitting states, execution-provenance loss by BINDING A RECEIPT to the value. Without one, the carrier could report the same-looking population from two different compilers -- the same defect one level down from the one the stage split closes. Every outcome that carries a population now carries an EmissionMeasurementSubject: entry, source revision, working-tree standing, and the sha256 of the two binaries actually invoked. It is established BEFORE the emitter runs, and a component that cannot be observed refuses the run rather than being recorded as absent -- an unobserved digest is not the digest of nothing. The one arm without a subject, EmissionSubjectUnestablished, is the one that took no measurement, so an unattributable population has no representation. The identity vocabulary is REUSED, not re-coined: CommitSha from extdeps.git.inspect, Digest from extdeps.crypto.hash. Minting a parallel identity vocabulary inside the instrument built to enforce single authority would be the violation it exists to measure. extdeps.tools.sha256sum gains one operation, DigestFile: CheckFile answers "does this file match this digest", which cannot be used to LEARN one. TWO -- A KILLED BUILD'S PREFIX READ AS A POPULATION. The decoder returned a population from any nonempty parseable prefix, so cargo emitting seventeen messages and then being SIGKILLed reported those seventeen as the answer. That is the truncated-observation-rendered-as-complete failure that created this lane, reproduced inside the instrument built to end it. cargo closes every run it performed with build-finished; a stream without one now refuses and says how far it got. Its `success` member is also now the authority on whether the build was clean, replacing the transport exit status observed beside the stream -- the terminal message is emitted BY the run being measured. Executed: PASS on the truncated-stream red, the terminal-message verdict in both polarities, and both provenance claims (a measurement names its compiler; an unestablished subject carries neither provenance nor population), with an existing green re-run as a regression control. Entry compile of the instrument after both corrections: 0 blocking, 145 files emitted. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The emit population states whether it is the whole population Requirement from smart-ram-730, relayed from deep-ant-102's finding, and it is a level finer than the phase split already in the carrier. THE FINDING, verified here by reading the emitter rather than taken on report: v1.05_emit_rust emit_rust is a sequence of early returns. Measured on the live file there are exactly two, both `return EmitResult { files: [], diagnostics }`, and while the first fires the checks after it NEVER EXECUTE -- two workflow-parameter diagnostics were observed masking eight anonymous-record ones, which had been standing the whole time. So any count taken over emit can be a PREFIX of the truth rather than the truth: not an undercount anyone can bound, but a count that stops silently at whichever earlier check fired. WHY THE EXISTING ARMS DID NOT COVER IT. They distinguish WHICH PHASE the instrument reached. This is finer: within one EmissionMeasured, emit itself may have returned before a later check ran, so two results that both honestly report "emit ran" can differ in whether a check even executed. A consumer reading the first concludes the entry has two blocking diagnostics; it has at least ten. THE DERIVATION IS EXACT, not a guess, which is what makes this a construction rather than a warning. Both early returns write NO FILES, and the CLI prints its `compiled:` line only where a tree was written. So a compile reporting emitted files ran the emit body to its end and its population is Complete; one reporting none is CompletenessUnestablished. That second arm is named for IGNORANCE rather than truncation on purpose: a refusal caused outside emit also lands there, and claiming such a population IS truncated would answer a question this observation cannot answer. Over-stating ignorance is safe; the opposite is the defect. AND THE COUNT NEVER TRAVELS ALONE. The size and the extent are rendered by ONE expression, so a report stating a population size always states the standing of the set it counted -- a separate optional row would let the number travel by itself, which is the entire failure. Executed: PASS on a refused population never reported as complete, a completed one reported as complete (so the extent is a real discriminator and not a constant), no report stating a population without its extent, and the existing carrier claim re-run as a regression control. Entry compile: 0 blocking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The ratchet consumer: an emit-clean frontier over a discovered roster, where an unmeasured subject is neither clean nor suspect tools.emission_entry_instrument answers one question about one entry and stores nothing -- it says so itself, and says gating is a separate decision with a separate argument. This is the consumer half of that sentence, and it is still not that gate: nothing here is enrolled in the required run. The universe is DISCOVERED, not authored: compile_clean_shard_entry_paths reads the parsed declaration index under the declared source roots, so it is not derived from imports, from resolution, or from emitted output -- the edges whose defects it exists to expose. The live specimen is gunbc.auth.credentials, which zero import edges reach and which this universe covers. Debt is carried at IDENTITY grain as admission rows, never as a count. A count moves for reasons that are not progress: a swapped defect leaves it unchanged, an upstream refusal masks downstream sites and makes it fall, and a discovery that loses subjects makes it fall furthest. The third standing is the point. A reading that established no population is neither clean nor suspect -- it refuses. Its discriminating control differs in exactly one field, whether emit reported a tree. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Hash the discovery policy into the roster digest; avoid two corpus-wide name collisions * Give the verdict-entry accessor its consumer: every verdict names its subject * Fix the one blocking diagnostic: a renamed fixture binding missed inside a list literal * Adopt the superseded contract: three-valued outcome, the enrolment wall as a construction, and both holes pinned by execution The clean-frontier ratchet has a hole deep-ant-102 named and I had not: Blocked{A} -> Blocked{A,B} never moves the frontier, so debt grows silently inside already-blocked subjects. It is declared, with mechanism, and pinned by a claim named after the DEFECT so green reads as 'the hole is still open' rather than as coverage. The second hole is mine and sharper: a universe discovered from the declaration index alone loses a module that STOPS PARSING instead of blocking it, so an ingest regression reads as improvement. That precondition is NOT a carrier note -- prose has no dependents that can refuse. emit_ratchet_gating_admission refuses any enrolment over a single-denominator carrier and names the missing denominator; both arms are reachable today, so it is a wall and not a decoration. Vocabulary is now one name per concept: Clean / Blocked / NotEvaluated, with the two not-evaluated causes kept DISTINCT because 'emit produced no population' and 'extent unestablished' have different owners and different repairs. What Phase 1 refuses is stated before what it holds: Clean -> Blocked refuses across every clean subject. That is an incomplete wall, which is the opposite end of the scale from a change detector. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Hole 2's mechanism was wrong: a parse failure under a recognized header refuses LOUDLY I wrote that a module which stops parsing vanishes from the universe. Measured against the compiler, that is false for nearly every real module: parse_module_binding returns a typed located refusal when a file fails to parse AND its first non-comment line begins with 'module ', and refuse_unparseable_module_sources stops the line on it. The silent arm is narrower and real: ModuleBindingUnclassified, which the index's own source documents as a conflation it cannot resolve -- fragments and parse failures land there together. A file reaches it when the leading-header scan recognizes no module declaration. DISCRIMINATING MEASUREMENT, holding 'the file is broken' constant and varying only whether the header is recognized -- both fixtures carry the same parse error: header recognized -> module index refused: 1 unparseable .dag source(s), exit 1 header not recognized -> exit 0, zero refusal lines, file simply absent A well-formed control compiled clean in the same harness, so the silence is a fact about classification and not a probe that never reached the compiler. The pinned claim is renamed to what it actually pins. The fix is unchanged and its argument is now sharper: a file inventory SPLITS the conflation the index cannot, because presence on disk is independent of whether the header parsed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Four stale sentences, not one: the corrected mechanism had not reached the strings that render it Review 55852 caught roster_denominators_text still saying 'a module that stops parsing vanishes' -- the claim the hole-2 correction in the same file had already established as false. Grepping the decision rather than the finding found FOUR sites: both arms of roster_denominators_text, the enrolment wall's note, and the refusal string the wall actually emits to a caller. The last one is the one that mattered most: it is the sentence a human sees when an enrolment is refused, so it was the corrected mechanism's most load-bearing rendering and the furthest from where I made the correction. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Delete the FIPS 180-4 fork in sha256sum: consume the citation extdeps.crypto.hash owns review 55859, REQUEST_CHANGES. sha256sum.dag re-minted sha256_algorithm_authority pointing at FIPS 180-4, forking the citation owned by extdeps.crypto.hash extdeps_external_authority_anchor. review 50411 had already refused the identical fork in the sibling sha512sum, whose note records the consume rule. THE FORK HAD ALREADY DRIFTED, which is why it is deleted rather than reconciled: the local row read .../180-4/final, the owning row reads .../180-4/upd1/final. Two spellings of one citation had begun to disagree about which revision of the standard is cited -- the decay 3 predicts, and the reason a second name for one fact is a correctness concern and not a style one. PROVENANCE, STATED BECAUSE IT CHANGES WHO OWES WHAT: the forked row is PRE-EXISTING ON MAIN, not introduced by #9190 -- that PR added DigestFile and the Digest-typed read only. This is debt the stack touched rather than authored. It is cleared here anyway: it is a real fork with a documented precedent refusing it, and provenance is not a defence for leaving one standing. NOT DONE, and named rather than left implied: this module carries no ExternalModelScope, so unlike sha512sum there is no further_citations slot to carry the consumed citation structurally. Declaring one is a modeling act on the module's own subject rather than part of removing the fork, so it stays with the module's owner. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * roster_identity had two declarers: a per-entry compile sees one, the floor sees both, so the collision was invisible to the check an author runs * The enrolment claim still asserted the pre-rename wording, so it went red on the branch where only the carrier had been swept * Two commentary rows in String carriers: DESIGN 4c names that shape as misplaced data, and this branch added both * Name the reader as the owner when a population is unreadable, and declare the third hole Review of #9213 (smart-ram-730, with a measurement from witty-swift-77's instrument lane) named a hole this carrier could not have derived from its own tree, and half of the defect was mine. THE HALF THAT WAS MINE. Every `EmissionUnreached` mapped to `PopulationUnproduced`, whose text asserts the emitter produced no population. For a talkative subject the emitter produced one perfectly well and the instrument's READER could not recover it -- `gunbc.WitnessBin.Run` keeps only the last 16 KiB of stderr and the entry-scope marker is printed near the head. So the verdict a human acts on named the wrong owner: DESIGN's not-applicable-rendered-as-malformed row committed inside the refusal text. `PopulationUnreadable` now carries the reader-side stages. The split is decided once, in `not_evaluated_cause_for_stage`, which is TOTAL over the stage vocabulary -- a stage added to the instrument has to be placed rather than silently inheriting the emitter as its owner. Neither arm is comparable to Clean and both still stop the line; the split repairs the text, it does not open a second route past the wall. HOLE 3, declared with the same honesty as the first two: the instrument can only measure QUIET subjects, and eight of nine sampled `dag/std` and `dag/extdeps` entries are three to five times over the capture window, so the READABLE subject is the exception over this carrier's universe. `dag/std/abi.dag` is in that universe by construction. Enrolment now has a second hard prerequisite beside hole 2's dual denominator. gunbc#9273 renames the refusal correctly and does not make those subjects readable -- the marker is bounded from the head and the window from the tail, so no value of the constant closes it. EVIDENCE: `a_read_that_failed_after_the_emitter_ran_names_the_reader_and_not_the_emitter` runs both directions over the same shape (green by execution; collapsing the decode arm back to `PopulationUnproduced` returns false -- mutated and measured, then reverted), and `an_unreadable_population_is_still_not_evaluated_and_still_refuses` pins that the owner split did not weaken the wall, admitted or not. Entry compiles 0 blocking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Hold the seam's asymmetry, and stop the sample from reading as a proportion Two corrections from the instrument lane, both recorded in the carrier rather than left in a message thread. THE SEAM IS ASYMMETRIC. The emit decode checks TRUNCATION FIRST, so only an untruncated stream reaches the marker check. `EmitScopeUnconfirmed` is therefore now unambiguous -- no truncation can hide inside it -- and this carrier names it as the compiler's problem with no hedging. But `EmitOutputTruncated` does NOT entail correct scoping: truncation dominates, so a stream that was truncated AND whole-tree lands on truncation and the marker question is UNANSWERED, not answered no. Reading it as "scoped fine, just clipped" is an inference the decode never made, and it is the one this carrier's not-evaluated wall exists to refuse. The cost is stated rather than discovered: that ordering removes detection of a whole-tree substitution on a talkative subject. This carrier does not ask for it to be reversed -- a scope verdict computed over a known-partial stream is a verdict about the TAIL and not about the compile -- but it means truncation grants this consumer NOTHING about scope. AND THE SAMPLE IS A SHAPE, NOT A PROPORTION. Nine entries were CHOSEN and sized, so "eight of nine" has a denominator of nine, not of the universe. It establishes that being over the capture window is ORDINARY rather than exceptional: enough to price the hole, not enough to state a rate. The carrier now says so and states no proportion anywhere, so a later reader wanting one has to measure the universe rather than scale this sample. Also records that the totality of `not_evaluated_cause_for_stage` binds the instrument by agreement: a new `EmissionStage` variant stops this fold compiling, and the measuring lane treats adding one as a change that has to reach this consumer. Entry compiles 0 blocking.

Measured at c271b75: the entry compile of the instrument itself is 0 blocking / 138 files emitted, and dag/extdeps/cpu/ampere.dag refuses at emit with 9 blocking / 119 advisory -- re-derived here, not carried from a brief. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Bind the execution subject, and require cargo's terminal message Two corrections from review on #9190, both narrowing. ONE -- THE CARRIER NAMED ITS STAGES AND NOT ITS COMPILER. Splitting the phase states is state-space de-conflation; it is not provenance, and the prose claimed provenance. DESIGN separates the two deliberately: conflation is repaired by splitting states, execution-provenance loss by BINDING A RECEIPT to the value. Without one, the carrier could report the same-looking population from two different compilers -- the same defect one level down from the one the stage split closes. Every outcome that carries a population now carries an EmissionMeasurementSubject: entry, source revision, working-tree standing, and the sha256 of the two binaries actually invoked. It is established BEFORE the emitter runs, and a component that cannot be observed refuses the run rather than being recorded as absent -- an unobserved digest is not the digest of nothing. The one arm without a subject, EmissionSubjectUnestablished, is the one that took no measurement, so an unattributable population has no representation. The identity vocabulary is REUSED, not re-coined: CommitSha from extdeps.git.inspect, Digest from extdeps.crypto.hash. Minting a parallel identity vocabulary inside the instrument built to enforce single authority would be the violation it exists to measure. extdeps.tools.sha256sum gains one operation, DigestFile: CheckFile answers "does this file match this digest", which cannot be used to LEARN one. TWO -- A KILLED BUILD'S PREFIX READ AS A POPULATION. The decoder returned a population from any nonempty parseable prefix, so cargo emitting seventeen messages and then being SIGKILLed reported those seventeen as the answer. That is the truncated-observation-rendered-as-complete failure that created this lane, reproduced inside the instrument built to end it. cargo closes every run it performed with build-finished; a stream without one now refuses and says how far it got. Its `success` member is also now the authority on whether the build was clean, replacing the transport exit status observed beside the stream -- the terminal message is emitted BY the run being measured. Executed: PASS on the truncated-stream red, the terminal-message verdict in both polarities, and both provenance claims (a measurement names its compiler; an unestablished subject carries neither provenance nor population), with an existing green re-run as a regression control. Entry compile of the instrument after both corrections: 0 blocking, 145 files emitted. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The emit population states whether it is the whole population Requirement from smart-ram-730, relayed from deep-ant-102's finding, and it is a level finer than the phase split already in the carrier. THE FINDING, verified here by reading the emitter rather than taken on report: v1.05_emit_rust emit_rust is a sequence of early returns. Measured on the live file there are exactly two, both `return EmitResult { files: [], diagnostics }`, and while the first fires the checks after it NEVER EXECUTE -- two workflow-parameter diagnostics were observed masking eight anonymous-record ones, which had been standing the whole time. So any count taken over emit can be a PREFIX of the truth rather than the truth: not an undercount anyone can bound, but a count that stops silently at whichever earlier check fired. WHY THE EXISTING ARMS DID NOT COVER IT. They distinguish WHICH PHASE the instrument reached. This is finer: within one EmissionMeasured, emit itself may have returned before a later check ran, so two results that both honestly report "emit ran" can differ in whether a check even executed. A consumer reading the first concludes the entry has two blocking diagnostics; it has at least ten. THE DERIVATION IS EXACT, not a guess, which is what makes this a construction rather than a warning. Both early returns write NO FILES, and the CLI prints its `compiled:` line only where a tree was written. So a compile reporting emitted files ran the emit body to its end and its population is Complete; one reporting none is CompletenessUnestablished. That second arm is named for IGNORANCE rather than truncation on purpose: a refusal caused outside emit also lands there, and claiming such a population IS truncated would answer a question this observation cannot answer. Over-stating ignorance is safe; the opposite is the defect. AND THE COUNT NEVER TRAVELS ALONE. The size and the extent are rendered by ONE expression, so a report stating a population size always states the standing of the set it counted -- a separate optional row would let the number travel by itself, which is the entire failure. Executed: PASS on a refused population never reported as complete, a completed one reported as complete (so the extent is a real discriminator and not a constant), no report stating a population without its extent, and the existing carrier claim re-run as a regression control. Entry compile: 0 blocking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The ratchet consumer: an emit-clean frontier over a discovered roster, where an unmeasured subject is neither clean nor suspect tools.emission_entry_instrument answers one question about one entry and stores nothing -- it says so itself, and says gating is a separate decision with a separate argument. This is the consumer half of that sentence, and it is still not that gate: nothing here is enrolled in the required run. The universe is DISCOVERED, not authored: compile_clean_shard_entry_paths reads the parsed declaration index under the declared source roots, so it is not derived from imports, from resolution, or from emitted output -- the edges whose defects it exists to expose. The live specimen is gunbc.auth.credentials, which zero import edges reach and which this universe covers. Debt is carried at IDENTITY grain as admission rows, never as a count. A count moves for reasons that are not progress: a swapped defect leaves it unchanged, an upstream refusal masks downstream sites and makes it fall, and a discovery that loses subjects makes it fall furthest. The third standing is the point. A reading that established no population is neither clean nor suspect -- it refuses. Its discriminating control differs in exactly one field, whether emit reported a tree. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Hash the discovery policy into the roster digest; avoid two corpus-wide name collisions * Give the verdict-entry accessor its consumer: every verdict names its subject * Fix the one blocking diagnostic: a renamed fixture binding missed inside a list literal * Adopt the superseded contract: three-valued outcome, the enrolment wall as a construction, and both holes pinned by execution The clean-frontier ratchet has a hole deep-ant-102 named and I had not: Blocked{A} -> Blocked{A,B} never moves the frontier, so debt grows silently inside already-blocked subjects. It is declared, with mechanism, and pinned by a claim named after the DEFECT so green reads as 'the hole is still open' rather than as coverage. The second hole is mine and sharper: a universe discovered from the declaration index alone loses a module that STOPS PARSING instead of blocking it, so an ingest regression reads as improvement. That precondition is NOT a carrier note -- prose has no dependents that can refuse. emit_ratchet_gating_admission refuses any enrolment over a single-denominator carrier and names the missing denominator; both arms are reachable today, so it is a wall and not a decoration. Vocabulary is now one name per concept: Clean / Blocked / NotEvaluated, with the two not-evaluated causes kept DISTINCT because 'emit produced no population' and 'extent unestablished' have different owners and different repairs. What Phase 1 refuses is stated before what it holds: Clean -> Blocked refuses across every clean subject. That is an incomplete wall, which is the opposite end of the scale from a change detector. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Hole 2's mechanism was wrong: a parse failure under a recognized header refuses LOUDLY I wrote that a module which stops parsing vanishes from the universe. Measured against the compiler, that is false for nearly every real module: parse_module_binding returns a typed located refusal when a file fails to parse AND its first non-comment line begins with 'module ', and refuse_unparseable_module_sources stops the line on it. The silent arm is narrower and real: ModuleBindingUnclassified, which the index's own source documents as a conflation it cannot resolve -- fragments and parse failures land there together. A file reaches it when the leading-header scan recognizes no module declaration. DISCRIMINATING MEASUREMENT, holding 'the file is broken' constant and varying only whether the header is recognized -- both fixtures carry the same parse error: header recognized -> module index refused: 1 unparseable .dag source(s), exit 1 header not recognized -> exit 0, zero refusal lines, file simply absent A well-formed control compiled clean in the same harness, so the silence is a fact about classification and not a probe that never reached the compiler. The pinned claim is renamed to what it actually pins. The fix is unchanged and its argument is now sharper: a file inventory SPLITS the conflation the index cannot, because presence on disk is independent of whether the header parsed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The dual denominator: a file the index cannot classify blocks instead of vanishing Closes hole 2. RatchetUniverse carries a second denominator -- a file inventory via shell.Find.FilesByNameSorted -- and a .dag file present on disk but absent from the declaration index becomes a SUBJECT whose outcome is EmitSubjectBlocked { cause: UnclassifiedByModuleIndex }. THE INVENTORY IS NOT A MORE CAREFUL INDEX. It answers a question the index cannot ask: module_path_index documents its unclassified arm as inseparable, and it is inseparable FROM THE INDEX, because fragments and parse failures look identical there. They do not look identical from the FILE SYSTEM, where presence on disk is independent of whether the header parsed. THE DENOMINATOR IS NOW DERIVED, NOT PASSED. RosterDenominators is no longer a caller-supplied field: the dual value is reachable only by holding a DualUniverse, which is reachable only by supplying an inventory. That closes the fold-time versus mint-time observation from review 55831 and smart-ram-730 independently -- a caller can no longer assert a denominator it has not earned. An unreadable root REFUSES rather than contributing an empty list, because a failure that shrinks the denominator is the exact defect this denominator closes. The hole-2 pin is FLIPPED to its regression control, not deleted: per 4b(4) the climb deletes the production handling it obsoletes, never the evidence that the higher rung is real. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Four stale sentences, not one: the corrected mechanism had not reached the strings that render it Review 55852 caught roster_denominators_text still saying 'a module that stops parsing vanishes' -- the claim the hole-2 correction in the same file had already established as false. Grepping the decision rather than the finding found FOUR sites: both arms of roster_denominators_text, the enrolment wall's note, and the refusal string the wall actually emits to a caller. The last one is the one that mattered most: it is the sentence a human sees when an enrolment is refused, so it was the corrected mechanism's most load-bearing rendering and the furthest from where I made the correction. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * A zero-file tree is not a clean entry: do not rest the load-bearing arm on the seed's printing discipline deep-ant-102 relayed a finding from bold-stag-236, who owns the producer: EmittedFileCount does not ASSERT the emitted/not-written distinction. FilesNotWritten is what the ABSENCE of the compiler's 'compiled:' summary line decodes to, and the compiler prints that line only when a tree was written. The distinction is inherited from the producer's printing discipline, which nothing pins. That lands hardest here. NotEvaluated is the load-bearing row of this ratchet -- an upstream refusal turning blockers into ABSENCE, with absence reading as zero, is the failure it exists to prevent. Populated only from FilesNotWritten, the row that makes the ratchet honest would rest on an unpinned convention in a frozen seed, and the failure would be exactly the one it guards: a run that emitted nothing reported as a run that emitted zero, and a subject reading CLEAN when it was never evaluated. Verified against the code rather than assumed: FilesEmitted { count: 0 } did derive EmitPopulationComplete and therefore Clean. So the derivation no longer depends on that convention for the dangerous direction. A zero-file tree is EmittedNothing, a third distinct NotEvaluated cause, so the hypothesised misprint lands in NotEvaluated and refuses either way. The convention still decides WHICH cause is reported -- a rendering difference rather than a verdict difference -- and the note says so. NOT CLOSED, and named: pinning the printing discipline itself needs a probe on a path that emits no tree, asserting the summary line is ABSENT rather than present-with-zero. That belongs beside the decoder, not inside this ratchet. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Restore the standing section my own block replacement deleted The dual-denominator edit replaced a range running from the fold to the enrolment wall, and the whole standing section lived between those two anchors: ratchet_failing_verdicts, ratchet_failing_rows, EmitRatchetStanding, emit_ratchet_standing and emit_ratchet_standing_text were deleted wholesale by an edit that named neither of them. Caught by the compiler, not by review or by reading the diff -- and the tell was 'function map not found in scope', a builtin, which is what a cascade looks like when a module loses declarations that later ones depend on. The nine errors it reported were one deletion, not nine defects. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Delete the FIPS 180-4 fork in sha256sum: consume the citation extdeps.crypto.hash owns review 55859, REQUEST_CHANGES. sha256sum.dag re-minted sha256_algorithm_authority pointing at FIPS 180-4, forking the citation owned by extdeps.crypto.hash extdeps_external_authority_anchor. review 50411 had already refused the identical fork in the sibling sha512sum, whose note records the consume rule. THE FORK HAD ALREADY DRIFTED, which is why it is deleted rather than reconciled: the local row read .../180-4/final, the owning row reads .../180-4/upd1/final. Two spellings of one citation had begun to disagree about which revision of the standard is cited -- the decay 3 predicts, and the reason a second name for one fact is a correctness concern and not a style one. PROVENANCE, STATED BECAUSE IT CHANGES WHO OWES WHAT: the forked row is PRE-EXISTING ON MAIN, not introduced by #9190 -- that PR added DigestFile and the Digest-typed read only. This is debt the stack touched rather than authored. It is cleared here anyway: it is a real fork with a documented precedent refusing it, and provenance is not a defence for leaving one standing. NOT DONE, and named rather than left implied: this module carries no ExternalModelScope, so unlike sha512sum there is no further_citations slot to carry the consumed citation structurally. Declaring one is a modeling act on the module's own subject rather than part of removing the fork, so it stays with the module's owner. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The claim asserting the refusal string went stale when I corrected the string Renaming 'module inventory' to 'file inventory' across the corrected prose left the one assertion that READS that string still grepping the old wording, so a_single_denominator_carrier_refuses_enrolment_and_names_what_is_missing went red. This is the same class as the four stale sentences review 55852 found, one turn later and caught by execution instead of by a reviewer -- which is the argument for asserting the string rather than the shape: a claim that only checked 'it refused' would have stayed green through a rename that broke what the refusal tells a human. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The printing-discipline probe pins one path, not the compiler: correct the remedy's stated size bold-stag-236, who owns the decoder, corrected the note I wrote naming the probe that would pin the compiler's printing discipline. A probe on a path that emits no tree establishes a property of THAT PATH, and v1 has more than one such path, so it raises confidence without closing the class. What closes it is the summary line emitted from a single site that cannot run without a tree -- present-with-zero having no PRODUCER rather than no observed instance. That is a v1 change and blocked under the seed freeze, so it is the class's next-rung trigger rather than work someone is declining to do. Recorded because a remedy described as bigger than it is becomes coverage nobody re-examines, which is the same failure as an inflated rung one level over.

… identically by both readers who implemented it (#9324) * Split the required run into two parallel jobs, and correct the ruling the split supersedes The required run's four phases are mutually independent and were also SERIAL, because one process runs them one after another. That is the expensive combination: the witness floor costs ~30-40 minutes and every other phase waited behind it for no reason a data dependency names, so the required check's wall clock was a SUM of things that could have been a MAX. Operator ruling 2026-08-25 ("we can add it as a parallel job in github actions - we can do the same for regen now, we have more runners" / "basically i would put regen + v2 full compile in one job, and witnesses into another one"). Two jobs, no `needs` edge: build regen first-generation comparison + the v2 emission compile witnesses the .dag parse sweep + the witness floor fold Each job makes ONE invocation of claim_executor and names a LANE. It does not name phases, order them, or wire one phase's precondition to another step's outcome -- which phases a lane owns is `RequiredCiPhase::lane`, an exhaustive match, so a phase belonging to no job fails to compile rather than going silently unmeasured. Every run prints a ROUTED line for each phase it does not own, so one job's log names the whole roster and where the rest is measured. THE 2026-08-20 CONSOLIDATION DIRECTIVE IS CORRECTED, NOT SILENTLY CONTRADICTED. It has two halves and only one is superseded. SURVIVES -- "within the gunbc binary": the phases still live in the binary and the step-ladder defect the consolidation fixed cannot return. SUPERSEDED -- "not at a github actions job level": parallelism is not expressible in one process, so the lane boundary is a job boundary of necessity, and what the directive protected against (sequencing and preconditions leaking into YAML) is exactly what does not cross it. Both halves are now stated in DESIGN's CI clause, in `gunbc.fabric_witness_run`, in `gunbc.witness_floor_workflow` and in the consolidation witness file. THE v2-EMISSION SUBJECT WIDENED in the same change, from `dag/std/abi.dag` to `src/v2/compiler/00_compile.dag`. The cost that argued for the smallest entry was a cost against a SERIAL run; the build lane's cost is now free up to the floor's duration. Measured by emitting both closures and differencing the file sets, the widening gives up exactly one file of coverage, `src/std_abi.rs`, and the row says so rather than claiming total subsumption. Executed evidence: - both lanes run, and route correctly: `lane=witnesses` runs parse and floor and routes regen and v2-emission; `lane=build` runs regen and v2-emission and routes parse and floor - an unknown lane word refuses with exit 2, it does not default - the v2 compiler entry compiles clean under the phase's own producer and pinned pool index (0 blocking) - six consolidation witnesses pass, including two new ones for the split - both new REDs flip under mutation and restore: adding a `needs` edge reds the parallel claim; collapsing to one job reds the two-lane claim - the lane-command claims verified through a scratch probe with a control that returns false NOT DONE, named rather than absorbed: no ratchet over the v2 compile's advisory population (a count pinned to the current tree is the oracle DESIGN §5 rejects; the honest form is an identity-grain monotone debt contract, a separate construction). Nothing else is restored from the deleted floor machinery. And the build step still compiles only the two bins the jobs run -- a declared `[[bin]]` outside that set is uncovered, with a live specimen on main today (`infer_semantics_witness`, six E0063s); widening to `--bins` changes what the required check covers and is an operator decision, so it is declared here rather than taken. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Correct the workflow module's own stale recital of the consolidation directive The supersession was recorded in DESIGN, in gunbc.fabric_witness_run, in the consolidation witness file and in the binary's own roster block -- and NOT in the paragraph inside gunbc.witness_floor_workflow that quotes the 2026-08-20 directive and describes the job as ONE INVOCATION, FOUR PHASES. That paragraph sits directly above the run step the split changed, so it is the one a reader reaches first, and leaving it standing would be the premise contamination this change exists to remove -- one document corrected while its own subject still recited the superseded ruling in the present tense. It now states both halves: 'within the gunbc binary' survives, 'not at a github actions job level' is superseded because parallelism is not expressible in one process. The step-ladder paragraphs below it are kept rather than rewritten, because what they establish is unchanged by the split and deleting them would take the reasoning with them. Also corrected: the step no longer passes 'the source roots and nothing else' (it passes a lane word), and the phase roster is four across two lanes rather than the 2026-08-21 three. Comment-only in emission terms: witnesses.yml regenerates byte-identical. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Make the split fail-closed: the required context now gates on both lanes Review of #9203 (review 55786, codex/gpt-5.6-sol) found the split fail-open, and it was right. Verified against the live ruleset rather than against the workflow, which is the only place the fact is visible: `passing CI` is active, carries NO bypass actors, and names exactly ONE required status check -- `witnesses`. A GitHub required context is produced by the JOB, not the workflow, so moving regen and v2-emission into a second job made them NON-BLOCKING: the required check would go green over a regen drift or a v2 emission break and the PR would be mergeable. That is strictly worse than the serial run it replaced, because the serial job carried every phase into the one context that gates. THE REPAIR, and why it is an aggregation job rather than a ruleset edit. The floor lane is renamed `floor`; the name `witnesses` moves to a job whose only step reads both lanes' results and exits nonzero unless both succeeded. The two lane jobs still carry no `needs` edge on each other and still start together -- only the aggregator waits, and it does nothing but read two results. A ruleset edit would also have worked and was rejected on a boundary DESIGN already records: the ruleset is not a `.dag` fact, so landing a change whose safety depends on someone editing a setting afterwards is a coverage gap with a promise attached and a real window in which the lane is unguarded. `if: always()` IS LOAD-BEARING, and its absence would have been the same fail-open one level in: a step with no `if` inherits `success()`, so it would be SKIPPED exactly when a lane failed, the job would report success, and a skipped required check does not stop a merge. The aggregator is the only place in this workflow that authors shell text, and that is stated on the carrier: there is no modeled value to render, because GitHub has no declarative "this job fails unless those jobs succeeded", and the nearest declarative form is the skip that fails open. The script is built from the job-id declarations rather than spelling `needs.build.result`, so a rename moves both sides together instead of rendering an unknown context as the empty string. WITNESS CORRECTION, not just an addition. `w_RED_neither_lane_waits_on_the_other` asserted the file contained no `needs:` at all -- the right claim for a workflow shape that was wrong, and a row that would have made this repair unrepresentable. It now forbids each single-lane edge and REQUIRES the aggregator's two-lane one, which distinguishes the serialization being forbidden from the aggregation being demanded. A third row asserts the gate runs and refuses. Executed evidence: all seven consolidation witnesses pass, and three mutations red the right rows and restore -- serializing floor onto build reds the parallel claim, dropping `always()` reds the gate claim, and deleting the aggregator reds the parallel claim. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * The aggregator's guard belongs at the JOB level: a skipped job never reaches its step Review 55795 and a peer session independently found, within minutes of each other, that the fail-closed repair was itself fail-open one level in. `needs` carries an IMPLICIT JOB-LEVEL CONDITION. A job that declares `needs` and no `if` is SKIPPED when any needed job fails, is skipped, or is cancelled. A skipped job never starts, so it never reaches its steps, so the step-level `always()` could not fire -- and a skipped required check does not stop a merge. The aggregator introduced to close the fail-open would have gone skipped-and-mergeable over precisely the failed lane it was there to catch, with the guard present in the file and reading as correct. `always()` AT JOB LEVEL, AND THIS IS THE ONE PLACE THAT DEPARTS FROM THE FILE'S `!cancelled()` HOUSE GUARD -- said in the carrier, in DESIGN and in the witness, because a reader who knows the convention will otherwise correct it back and reopen the hole. Every other guard here decides whether a STEP runs inside a job that is already running, where `!cancelled()` is right. This one decides whether the REQUIRED CONTEXT EXISTS AT ALL, and under `!cancelled()` a cancelled run leaves it skipped rather than answered. That would turn the outcome on a question about GitHub nobody here has executed -- does a skipped or cancelled required check block a merge -- and the response is not to go measure it but to make the answer not matter. Under `always()` the job always runs, always reads both results, and always reports on its own terms; SKIPPED disappears from the required context. Cost, named: a lawfully superseded run now reports this context red rather than cancelled. That is the correct reading, not a regression -- a superseded run's evidence must not admit a merge. THE WITNESS WAS WRONG IN THE SAME WAY AND IS FIXED WITH IT. It asserted `if: always()` appeared SOMEWHERE in the file. It did -- on the step -- so it went green over the defect. That is DESIGN's total-at-the-level-examined failure: true, and about the wrong level. It now discriminates on emitted INDENTATION, which is the only thing in the text that separates the two levels (a job key at four spaces, a step key at eight), and asserts both. Executed: the strengthened row PASSES on the fix and FAILS on a mutation that removes the job-level guard -- i.e. it catches the exact defect that shipped. All seven consolidation witnesses pass. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Say what the v2-emission phase actually covers: 24 of 42 compiler modules, measured Operator clarification, 2026-08-25: "the intention is to v2 build ALL of the .dag compiler files, and then ratchet THAT count in CI". Measuring against that ask showed this PR's own prose overclaims, so the claim is corrected before anything is built on it. MEASURED, by emitting the entry and joining the emitted file names against the module line of every src/v2/compiler/**.dag: of the 42 modules under src/v2/compiler/, 00_compile's closure emits 24. Eighteen are absent, including ingest, emit_module, emit_host, emit_produced, emit_semantic_decl, program_partition and self_host. Counting the self_host/ subtree the compiler namespace is 69 modules, so the shortfall is larger again. "The widest closure one entry names" was true and is kept; "full v2 compile" invites the reading that the phase covers the compiler, and it does not. That reading is exactly the premise contamination this repository keeps paying for, so the row now states the covered population rather than leaving a reader to assume it. AND A METHOD NOTE THAT COST A MEASUREMENT: a static import-closure estimate CANNOT substitute here. It reports ZERO compiler coverage for this entry, because this corpus resolves most cross-module references without import lines. Only the compiler's own reference-derived closure is the truth, which means a covering entry set cannot be derived from the import graph either -- it has to be measured by emission. The widening itself is NOT taken here: it needs either a measured covering entry set or a whole-tree emission whose cost has to be known before it is enrolled in a required lane. This row makes that widening a change to a known number instead of an assumed one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Receipt: the gate refused two cancelled lanes, and 'abandoned' is a state nobody knew about Run 32883390033 (2026-08-25) ended BOTH lanes by a fleet event with no push involved. The aggregator ran anyway under its job-level always(), read the two results, refused, and published the required context witnesses as a FAILURE. That is this gate's first executing receipt and it is the behaviour the pre-repair shape could not produce -- there, the aggregator would have been skipped. AND THE RUN SURFACED A needs RESULT VALUE NOBODY HERE KNEW WAS REACHABLE: BUILD="cancelled" FLOOR="abandoned" The gate handles 'abandoned' correctly only because it compares != "success" rather than enumerating bad states. The form a reader's instinct reaches for -- == "failure" || == "cancelled" -- would have admitted it and reported the required context GREEN over two lanes that never ran. So the strict inequality is now recorded on the carrier as a measured fact rather than left as a style choice, because the obvious 'improvement' to an explicit list is a fail-open. That is the difference between a closed vocabulary and a remembered one: the inequality admits exactly one state and refuses every other, including the ones the author has never heard of.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Record the argument against always() beside the decision to keep it A peer session raised the strongest objection to the job-level always() guard, from GitHub's documented semantics rather than from a measurement, and it is correct on every fact it asserts: always() is the one condition that survives workflow cancellation, cancel-in-progress is armed on every pull_request so this fires on the MODAL event, and it destroys the cancelled/failed distinction at the RECORD level where nothing can recover it. That ambiguity cost that session hours in one day, diagnosing 38 lawful supersessions as a false-red epidemic. The file's house guard really is !cancelled() everywhere else. It is not taken, and the reason is an asymmetry about WHICH HEAD PAYS. Checks are tracked per head SHA, so a superseded run's red lands on a head that by construction is never merged -- the push that superseded it created the head that will be. always() is noisy on ABANDONED heads. !cancelled() moves the cost onto the LIVE one: a lane killed with no replacement run coming, observed twice on 2026-08-25 (once with runner_name empty and zero steps, once with both lanes ended at 18:43 and no push involved), leaves the required context SKIPPED on the head that is still the merge candidate -- which is precisely the unmeasured GitHub behaviour the guard exists to stop depending on. Quiet-and-unknown on a live head is worse than loud-and-definite on a dead one. The mechanism half of the objection is now MEASURED rather than documented: run 32883390033 had both lanes ended by a fleet event, and this job published failure while the run conclusion was cancelled. So the behaviour the objection predicts is real; what is disputed is only whether it is the wrong trade. Recorded in the carrier rather than answered away, so the next person who wants !cancelled() finds the case already made instead of rediscovering it. Comment-only in emission terms: witnesses.yml regenerates byte-identical.

ONE. The build lane bootstraps `cargo build --release -p v1-compiler --bins`. Host-Rust coverage of the whole declared bin roster is a fact somebody has to establish, and a bin no consumer selects is precisely the one that rots unobserved -- #9205 repaired one such bin after it had drifted with nothing building it. The floor lane keeps the two bins it executes; the lanes are runtime-independent, so their bootstraps are independent CPU rather than a shared prerequisite one could save. TWO. THE DAGLANG COMPILATION FORK IS CLOSED. `cli_run` now carries `CompileSubject{Entry|PrimaryRoot}`, `CompileRequest` and `compile_emission`, and the transaction owns indexing and precedence, subject source-set construction, census fill, memory admission, resolution and compilation, the blocking/advisory split, silent-pick capture and the disposition. `compile_entry_emission` survives as a wrapper with no semantics of its own. Before this, `gunbc compile` without `--entry` implemented a SECOND index/load/resolve/admit/compile/refuse pipeline in `main.rs`, beside the transaction rather than through it. They differed in ways nobody had decided: the whole-root arm applied the memory-admission gate and the entry arm did not, the entry arm ran the silent-pick gate inside the transaction and the whole-root arm ran it around the outside, and their refusal subjects were spelled differently. That is DESIGN section 3's two-authorities-for-one-fact, and it is the reason a whole-tree ratchet could not be built on the existing phase: the ratchet would have observed a different producer from the gate beside it. The arms' real differences are KEPT, which is why this is a coproduct and not a flag: admission is asked of the whole root and not of an entry (an entry's working set is its closure, measured to fit on the runner that SIGKILLed a whole-tree run -- an unasked question, not an all-clear), and the closure derivation genuinely differs (reference-derived for an entry, import-edge for a root where every module is already an entry). A `PrimaryRoot` matching no module refuses at `subject-discovery` rather than reporting `Completed { 0 }`, which would be the empty-observation narrow. THE DELETION WAS THE CENSUS. Routing the whole-root subject through the transaction left ~200 lines in `main.rs` with no caller, and rustc then found seven more private copies of module indexing and import walking -- `extract_module_path`, `report_moduleless_dag_entry_skips`, `extract_import_paths`, `insert_module_path`, `index_source_root`, `build_module_index`, `resolve_transitively_with_seen`. All deleted; their two tests re-pointed at the surviving `cli_run` authority rather than retired with the function, per DESIGN section 4b(4). Multi-target (`--target a,b`) still walks the old loop and is named rather than exempted. THREE. `pr_owner` AND `cycle_owner` REFUSED FOR A REASON THAT IS NOT IN `review_codex.dag`. `owner` has TWO declarations in the flat whole-tree namespace -- `data owner` in `gunbc.tools.review_codex` and `fn owner(uid, gid)` in a srv3 path-ownership test -- and the winner is fold order. When the function won, the CLI defaults resolved to it and refused with `must be a string, int, float, bool literal, or data reference`: two blocking diagnostics in a file that had not changed, produced by a test helper in another directory. The discriminating pair is what establishes that, and it was measured rather than reasoned. `repo` is declared beside `owner` in the same module, has no `fn repo` anywhere in the corpus, and does not refuse. `default_model` IS declared twice -- `tools.review` and `tools.review_codex` -- and does not refuse either, because both declarations are data, so either winner satisfies the default's requirement. Collision alone is not the fault; collision ACROSS DECLARATION KINDS is. Fixed by renaming the test helper to `owner_spec`. The class is untouched and the annotation says so: a bare cross-kind homonym is still writable and still resolves by fold order. Its next-rung trigger is a refusal at name resolution when one flat name carries declarations of different kinds -- decidable from the index the compiler already builds -- not a roster of forbidden names. FOUR. THE REQUIRED-LANES GATE IS BUILT AS NODES, NOT SPELLED AS TEXT. `gunbc.required_lanes_gate` constructs it through `v2.extdeps.languages.bash_build` and `witness_floor_workflow` serializes it through `v2.workflow.bash_command_fold_serialize` -- the `tools.build_step` -> `v2.workflow.build_step_emit` precedent. Raised as review 55836's medium-as-string finding, which was correct: I had argued no modeled value existed to render, and the language was fully modeled the whole time. Declaring a language-layer gap without enumerating the language is the failure DESIGN records in its own section 6 receipt. The Rejected arm REFUSES rather than rendering nothing, because an empty `run` exits 0 and would make the required context green over two lanes it never read. The emitted text was executed against all three arms: success/success passes, success/failure and cancelled/abandoned each print the error and exit 1. ALSO LANDED, NOT YET WIRED: `gunbc.v2_rustc_debt` models the monotone identity ledger -- key (emitted-crate-relative path, rustc code), admission iff observed equals the current ledger AND the current ledger is a multiplicity-wise subset of the baseline's -- with eleven fixture arms that author both input and expectation. Both totals are receipt-only and reach no verdict. Its host observation is deliberately absent: an observer built before a whole-tree emission can be produced would be an observer with no subject. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * The subject is a field, the precedence root is a refusal, and the fork is three callers wide FOUR CORRECTIONS, three of them from an operator ruling on the measured report and one from the census that ruling asked for. ONE. THE ALIAS DIRECTION WAS BACKWARDS. It read `pub type CompileRun = EntryEmissionRun`, which makes the generic name an alias of the entry-named authority -- so the canonical carrier stays the one named for a subject it no longer describes, and every reader is sent to a type whose name contradicts two of its three uses. `CompileRun` and `CompileDisposition` are now the types; the entry-named spellings are the compatibility aliases that disappear with their last caller. TWO. `run.entry` SILENTLY WIDENED TO HOLD A DIRECTORY. A consumer reading it after a `PrimaryRoot` compile got a root from a field promising a file -- one name, two meanings, which is the section 3 violation the fork closure exists to remove, reintroduced one field down. It is now `subject: CompileSubject`, and the receipt names the ARM rather than the path: `subject=primary-root:src/v2`, not `subject=src/v2`. The two read identically to a human and differently to anyone deciding whether a run measured what it was asked for, which is the whole reason the field exists. THREE. THE SUBJECT AND THE PRECEDENCE ROOT NOW HAVE TO AGREE, AND DISAGREEING REFUSES. The trap is entirely in argv order and invisible from the receipt: the live workflow passes `--source-root dag --source-root src/v2`, and the no-entry CLI law is `PrimaryRoot(source_roots[0])`, so THAT argv asks for `PrimaryRoot(dag)` with `src/v2` as a pool. A caller who means "compile v2" and writes the roots in the workflow's habitual order gets the other subject, compiles ~2000 different modules, and is told the compile completed. This is not a scope difference, it is a RESOLUTION difference, and it already cost a measurement: `dag`-primary refuses on two `review_codex` CLI defaults that `src/v2`-primary never reaches, and `src/v2`-primary refuses on 36 diagnostics `dag`-primary never sees. The 9.06 GiB peak and the `owner` diagnostics reported earlier are the `dag` subject; they were reported under a heading that implied the v2 one. A ledger bootstrapped from the wrong subject is not a coarser ledger, it is a ledger about another population. `primary_root_agrees_with_precedence` makes the disagreement unwritable rather than merely detectable. FOUR. THE FORK IS THREE PRODUCTION CALLERS WIDE, NOT ONE. The census over `compile_sources`, `compile_sources_with_options`, `compile_to_resolved_with_options`, `emit_resolved_for_target` and `stage0_self_compile_refusal_message` classifies every caller: 46 compiler_tests / compiler_tests_rust kernel test, legitimate 2 v1_probe_emit_interp generated kernel probe, legitimate 2 v1_compiler_emit_rust compiler implementation, legitimate 9 cli_run compile_emission implementation 5 main.rs DECLARED VIOLATION (multi-target loop) 2 required_regen_host DECLARED VIOLATION (needs ExactSourceSet) 2 bin/bootstrap_witness DECLARED VIOLATION (not previously named) `bootstrap_witness.rs` compiles EVERY `.dag` file under `dag/` to Rust, which is exactly the invariant's subject -- a repository source population producing an artifact tree -- so it is a production route and not a kernel probe. It carries its own `build_module_index`, `build_module_index_for_roots` and `resolve_imports_transitively`: a FOURTH private copy of the machinery this branch deleted from `main.rs`, in a 1289-line binary the floor lane builds and runs. It can disagree with the transaction about what the `dag/` population IS, and nothing would say so. None of the three violations is closed here. They are named, classified, and ordered: multi-target into the request as a target set, then regen and bootstrap_witness through an exact-source-set subject, both of which select a population by their own authority rather than by directory. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Hoist two §4c-illegal in-body annotations, and restore the module-less skip report the consolidation dropped Two fixes, both of them corrections to my own work on this branch. §4c: `v2_rustc_debt_ratchet_test.dag` carried two `//` lines INSIDE a `test fn` body. Only module-item grain is modeled, so strict preparation refused and the build lane went red on #9242. Hoisted above the declaration. An awk brace-depth census over every file this branch touches confirms no in-body annotation remains. Module-less visibility: the deletion note in `main.rs` claimed the module-less-entry skip report was "the one behaviour with no counterpart" in `cli_run`. That was FALSE -- `report_moduleless_dag_entry_skips` and `moduleless_dag_entry_paths` are both `pub` there with tests, and were never deleted. The note asserted an absence without grepping for it, which is the one claim a later reader will not re-check. The behaviour is now wired into the transaction's `PrimaryRoot` arm through those same two functions. It matters there specifically: the subject is discovered from `index.source_files`, keyed by module path, so a `.dag` under the root with no `module` declaration is absent from the subject and the transaction would report `Completed` over a population that silently excluded it. The empty-root refusal cannot catch this, because a root holding one good file and one forgotten one is not empty. It REPORTS rather than refuses, declared as the weaker arm: a module-less `.dag` is a legitimate parse fixture today, so refusing would break real callers. Terminal form is a total role classification under which an unclassified `.dag` refuses. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Route multi-target compiles through the one transaction, validate all three debt populations, and read the verdict as itself Six review findings, each fixed rather than answered. MULTI-TARGET REGRESSION (blocking). `--source-root X --target rust+dag` fell past the routing gate -- which conjoined the subject with `render_targets.len() == 1` -- into a branch whose only remaining subject is `--source-dir`, and exited "provide --source-root or --source-dir" over an argv that provided one. `CompileRequest` now carries a target VECTOR: resolve once, emit per target, and materialize NOTHING until every target has completed, so one target's tree is never left on disk beside another's refusal. The disposition, the blocking count and the refusal are over the whole emission set, not the first target. Single-target callers -- every required one -- run the identical computation, because `compile_sources_with_options` IS `emit_resolved_for_target ∘ compile_to_resolved_with_options`. Two discriminating arms: two targets produce two named emissions from one resolution, and a request naming NO target refuses at its own `target-admission` phase rather than reporting `Completed { emitted_count: 0 }`. DEBT LEDGER FAIL-OPEN (blocking). Positivity and uniqueness were asked of the LEDGER only. A duplicated key in the OBSERVATION makes the multiplicity lookup answer with whichever row the fold reaches first, so the comparison silently compares the wrong quantity and the run reads as held. All three populations are now validated -- positivity, uniqueness, and strictly ascending canonical order -- through one `DebtPopulationMalformed { population, cause, keys }`, with `population` a closed coproduct because the three have different owners and different repairs. Order refuses rather than sorts: sorting would make two textually different ledgers compare equal and stop a ledger diff being reviewable. THE BLIND-SPOT FIXTURE AUTHORED NO SUBSTITUTION. It passed `one_error()` on both sides and CLAIMED in prose that the two were different errors, which made it a tautology wearing a substitution's name. It now authors `SyntheticRustcDiagnostic` values carrying a latent site, asserts FIRST that the two populations differ, and then that bucketization erases the difference. NO BOOLEAN COLLAPSE OF THE VERDICT (review 55911). `rustc_debt_verdict_admits` matched every variant and returned one bit, so a consumer refusing on it prints "the ratchet refused" and the author re-derives the cause by hand. Deleted. Every test arm now asserts WHICH verdict, which is strictly stronger: an arm authored to provoke `LedgerExceedsBaseline` used to stay green when the contract refused it as malformed for an unrelated reason. VOCABULARY. `admitted_multiplicity` -> `multiplicity`; `identities` -> `buckets`, in the model, the receipt and the test names -- the count is per (path, code) bucket and calling it an identity is the inflation the blind-spot arm exists to deny. RENAME FINISHED. The entry-named aliases are deleted, not merely re-pointed; two spellings for one type is the same §3 violation one layer out. Also: the census behind "one compilation concept" is now stated at CALL-SITE grain with its forks named, the `CompileSubject` comment no longer calls the import walk "the authority" (it under-pulls by construction -- the namespace is flat -- and the census fill covers the difference), the precedence check declares its rung and its terminal `SourcePool` form, and a `TypeEnv` field missing at one test site is filled so `cargo test --lib` builds at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Build the unrenderable-gate refusal from the Bash grammar too, and split the unwired debt model out of this PR Review 55923, both findings, neither deflected. THE RAW SHELL FALLBACK IS DISSOLVED, NOT MARKED. `required_lanes_gate_unrenderable_script` was an executable program spelled as a String and handed to a RunStep -- the medium-as-string violation this PR otherwise removes, surviving in the one arm nobody reads, inside the module whose own header argues against exactly that. The refusal is now Nodes in `gunbc.required_lanes_gate`, beside the gate it stands in for, serialized through the same fold. The outcome is three-state rather than two, and the third state is what removes the last fabricated value: the gate serializes -> the gate; the gate rejects but the refusal serializes -> the refusal, which stops every run loudly; both reject -> Absent, and `expected_witness_floor_yml` returns `WitnessFloorGenerationRefused` so no yaml exists at all. A Rejected fold can no longer reach a published step. The one remaining `""` is not a program and is reachable only when emission has already refused -- Daglang is total, so some value must inhabit the arm; what matters is that it is not a second spelling of a shell program and that no emission path reaches it. Verified rather than asserted: `required_lanes_gate_is_renderable` returns true by execution, and regen exits 0 with the workflow yaml BYTE-IDENTICAL -- only the unreachable arm moved. ON THE "on-carrier bash-emission scaffold marker": no such convention exists in this tree. A whole-tree search finds no `bash_emission`, `hand_shell` or `model_vs_runner` carrier. Removing the raw string makes the marker moot either way, which is the stronger repair. THE DEBT MODEL LEAVES THIS PR. `dag/gunbc/v2_rustc_debt.dag` and its fixture are removed and travel to the change that lands their consumer. The earlier review from the same provider offered keeping this PR open as the integration vehicle and I took that; a measurement since has changed the calculus. A whole-repo emission REFUSES ON MEMORY ADMISSION on the current runner class -- measured on BuildBuddy: budget 6.58 GiB against the modeled 7.00 GiB demand, `WholeCorpusCompileBudgetBelowMeasuredDemand`, zero files emitted. So the observer cannot be built until the resource-grant boundary is decided, and that decision is the operator's. Holding a foundational compilation PR open behind someone else's decision is worse than either option the review named. What remains here is the compilation consolidation and the gate repair: coherent, with consumers, mergeable on its own. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * A target name carried beside its target can disagree with it; derive it. And the fork census omitted a fork Two remarks from the side-channel review, both verified against the code, both real. THE (NAME, TARGET) PAIR IS COLLAPSED TO A TARGET. `CompileRequest.render_targets` carried `Vec<(String, RenderTarget)>`, so `("dag", RenderTarget::Rust)` was constructible: two spellings of one fact, free to disagree, with the NAME deciding which directory a target is written to while the TARGET decided the bytes written into it. That is the §3 violation this transaction exists to remove, reintroduced one field down and in the same PR that removes it elsewhere. The name is now DERIVED through `render_target_name`, which is the CLI parse's inverse, so the disagreement has no representation rather than being checked for. `parse_render_targets` discards the authored spelling deliberately, because it is recoverable. THE CALL-SITE CENSUS OMITTED `required_regen_host`. `compile_stage0` calls `compile_sources` directly over `regen_input_sources` -- a fourth fork, and the census whose entire purpose is to enumerate forks reported it as absent. The file appeared in the file-level count I ran and did not survive into the call-site list I wrote from it, which is the incomplete-enumeration class this repository has recorded against itself twice before: a list transcribed from a wider measurement is not the measurement. It is now listed with its subject (an EXACT SOURCE SET from the regen roster -- neither a root nor an entry, so neither existing subject describes it), its terminal form, and the hardcoded refusal subject it still passes. The omission is recorded in the census itself rather than quietly corrected, because a census that has been wrong once should say so. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * The refusal arm the PR defends was the wrong shape, and nothing executed could have caught it Review 55928, plus four findings from the thread review that survive at this head. THE MIDDLE RUNG WAS DEAD. `required_lanes_gate_unrenderable_stmts` was declared `-> List<Node>` and returned `bash_build_stmt_list_from_nodes(...)`, which is a single `Node`. Its caller passes it as `stmts: List<Node>`. So the arm this PR argues must stay executable -- gate rejects, the refusal still serializes, the run stops loudly -- was the wrong shape in exactly the place the argument is about, while the in-file receipt said it was Nodes through the same fold. Returns the raw list now, like `required_lanes_gate_stmts` beside it. THE REASON IT WAS POSSIBLE IS THE REAL REPAIR: the claim lived in prose, so nothing could contradict it. `the_unrenderable_gate_refusal_serializes_and_stops_the_line` now runs the fold over the refusal and reads the program back -- it must serialize, and must carry both the `::error::` annotation the operator sees and the `exit 1` that stops the line. THE CONTROL FLIPS, MEASURED RATHER THAN ASSUMED. Fixed shape: true. Defect restored: `PatternMatchFailure`, the fold choking on a Node where the list belonged. ONE HONEST QUALIFICATION: the red arrives as a RUNTIME ERROR, not a returned false, which is a weaker red than a clean false -- an erroring probe stops rather than asserting anything about its subject. Recorded because "the control flips" alone would overstate it. DUPLICATE TARGETS REFUSED. `--target rust+rust` parses to two targets, and each emission's directory is derived from the target, so both land in `output_dir/rust` -- the second overwriting the first while the run reports two completions. Refused at `target-admission`, not deduplicated: collapsing it silently answers a request nobody made and destroys the signal that the argv is wrong. THE MODULE-LESS WALK NO LONGER DROPS READ FAILURES. `if let Ok(content)` narrowed "every `.dag` under the root" to "every READABLE one" while still reporting under the wider name -- the empty-observation narrow inside the population whose entire job is to report what got dropped from the subject. Now a typed refusal at a `subject-read` phase. DOCUMENTATION THAT LIED. The root-order ruling sat immediately above `names_at_least_one_target`, so Rust attached the precedence contract to target admission; moved. "One entry, one render target" and "One entry's emission transaction" corrected beside code that handles two subjects and a target vector. The alias note's history example read `pub type CompileRun = CompileRun`, which is not a direction. And "reference derivation is not used here and that is not an oversight" sat directly above the fixpoint call that falsifies it -- it is used, because an import edge is weaker than a reference in a flat namespace and the walk under-pulls across the pool boundary. Regen exits 0 with no artifact drift. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Restore the entry-scope marker as a typed receipt: I deleted a consumer's evidence while tidying a sentence Three findings from the thread review, verified against the code before acting. THE SCOPE MARKER WAS MINE TO LOSE AND I LOST IT. Main prints "resolved N sources (reference-derived closure), M indexed modules"; consolidating the two CLI pipelines into one generic line dropped the parenthetical. It existed at the merge-base, so this is a regression on this branch and not a collision. `gunbc.emit_diagnostic_observation` `emit_entry_scope_marker` (landed on main via #9190, AFTER my change) matches that exact text and returns `EmitScopeUnconfirmed` when it is absent -- specifically so a whole-root compile cannot be reported as one entry's measurement. Merging main unchanged would have made every per-entry emission measurement refuse, from an edit that reads as prose cleanup. RESTORED AS A VALUE, NOT AN ADJECTIVE. `CompileScopeReceipt` is derived from `CompileSubject`, so the receipt cannot disagree with the run and cannot be lost by rewording. The entry arm carries the marker; the primary-root arm now STATES what it measured instead of being silent, so a consumer no longer has to infer scope from argv or file counts. The Rust literal and the `.dag` `data` row are two spellings of one fact -- unavoidable while that authority is `.dag` and this seed cannot read it -- so the constant is named `EMIT_ENTRY_SCOPE_MARKER` and cites its authority, making the pair greppable. THE TEST ASSERTS BOTH HALVES. Marker present on the entry arm, ABSENT on the primary-root arm. A receipt that carried it on both would be worse than one that carried it on neither: the marker exists to make the substitution refusable. THE PANICKING TRAVERSAL. My earlier "typed refusal" fixed the per-FILE read and left the DIRECTORY walk calling `collect_dag_files`, which is `collect_dag_files_result(..).unwrap_or_else(|e| panic!(..))`. A missing root, a regular file as root, or any `read_dir` failure bypassed `CompileDisposition` entirely. That was half a repair wearing the whole one's name; the walk is fallible now. TARGET ADMISSION ORDERING, PROVEN RATHER THAN ASSERTED. The new arm passes a subject that CANNOT be discovered, so if the duplicate-target refusal came after subject discovery the run would refuse at `entry-read` instead and the arm would fail. It proves the ordering, not merely the refusal. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * The all-or-nothing materialization proof, with a RED that is actually authorable The CLI writes a tree only after the AGGREGATE disposition is `Completed`, so one target's refusal must withhold another target's finished files. That claim was asserted by the arm's structure and by nothing executable. BEFORE WRITING THE TEST I CHECKED WHETHER ITS RED CAN BE PRODUCED AT ALL, because a check whose red is unauthorable is a decoration -- permanently green by construction and worse than absent, since it gets cited as coverage (DESIGN §4b). It can: `file_emission_refusal` applies `target_renders_file_transport` FIRST and separately from `file_binding_refusal`, and that gate answers `Rust => true` with Python, Go and Dag all false. So a WELL-FORMED file-transport operation emits clean on Rust and refuses `FileTargetNotModeled` on Go. MEASURED on the new fixture root before any assertion was authored: `--target rust` emits 7 files with 0 diagnostics; `--target go` refuses, naming target 'go' and the missing file realization handler. The fixture is deliberately well-formed -- renderable path, product output shape, only modeled channels -- because a fixture with a real defect would refuse on BOTH targets and the test would pass for the wrong reason. Also measured, and it corrects the assumption I would have coded against: ordinary modules complete on every target (rust 6 files, go 3, dag 1, python 3, zero diagnostics each), so the refusal genuinely has to come from the transport gate rather than from picking an "unsupported" target. The test carries a single-target control (rust alone completes with a non-empty tree, so a future change that breaks the fixture cannot leave the test quietly asserting nothing), pins the refusal to the target-gate cause rather than any refusal, and asserts the refused run still holds the SAME file count the control emitted -- unwritten. That last assertion is the whole content: it distinguishes "the arm withheld a finished tree" from "there was nothing to write", and without it the property is vacuous. Also collapses `authored_import_names`, which the merge from main left specified THREE times in one `#[cfg(test)]` struct literal, breaking the entire lib-test target. A clean merge with no conflict, and no gate could see it: CI builds the binary and the Rust suite left CI on 2026-07-11. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * The five transaction tests were unexecutable as written; they now execute, 5 passed The PR body said these arms were "type-checked only". That was too kind to them. They were not merely unexecuted -- they were UNEXECUTABLE: a test binary's cwd is the PACKAGE root while the fixtures live at the repo root, so every one of them panicked in `index_source_root_into_module_index` with `source root does not exist` before reaching a single assertion. Discovered by running the new atomic-materialization test, not by reading. FIRST FIX WAS WRONG AND THE WRONGNESS IS THE POINT. `set_current_dir(workspace_root())` looks correct and greened four of five. It is a race: cwd is process-global and cargo runs these tests in parallel, so a DIFFERENT PAIR failed on each run -- 4 passed/1 failed, then 3 passed/ 2 failed, with identical code. A flaky green here would have been worse than the original failure because it would have read as proof. Replaced with absolute paths derived from `workspace_root()`, which has no shared mutable state to race on. Also reads the `Refused` arm rather than routing it through `cause_of`, which destructures `NotExecuted` only. The first draft panicked on its own success: the run WAS `Refused { phase: "emit", cause: "... target 'go' ... transport emission is not modeled" }`, which is exactly what the test asserts. MEASURED: `cargo test --lib -p v1-compiler` over the five, remote: 5 passed, 0 failed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Assert the withheld tree BYTE FOR BYTE, not by file count The atomicity test compared the refused run's rust emission to the control by `files.len()`. That is weaker than the property the test exists to establish: a refusal that silently substituted DIFFERENT bytes at an equal count would have passed, and "the refusal also changed the output" is exactly the failure the all-or-nothing claim rules out. The control now captures (path, content) for every rust file and the refused run is compared against it verbatim. Raised by review rather than found here, and conceded rather than argued -- an equal-count assertion is not a cheaper version of the right one, it is a different and weaker claim. MEASURED after the change, remote: 5 passed, 0 failed over the five transaction tests. UNCHANGED AND STILL DECLARED: this proves the TRANSACTION refuses while holding a complete tree. It does not observe the filesystem, because `write_output_files` lives in main.rs -- an edit moving it back inside the target loop would still pass. The test's own comment and the PR body both say so. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SAQiYQiQ7SsdxvotAFbUFc * Name the third arm: a two-way rule over a three-state domain misread by both readers who implemented it The comment beside the /proc/vmstat reads in `floor_resource_sample` documents a discrimination with two arms -- pswpin rising with pgmajfault is swap and not this lane's problem, pgmajfault rising with pswpin flat is file-backed mapping churn and IS this lane's defect. The domain has three states. Zero-and-zero has no arm. THIS IS NOT A HYPOTHETICAL. Two readers implemented the documented rule independently while investigating the floor-lane cancellations, and BOTH classified zero-and-zero as mapping churn -- 26 intervals in one reading, 6 in the other. That inverts the conclusion: churn is a defect this lane owns, quiet is the absence of one. A rule stated as a dichotomy over three states hands every faithful implementer the same misreading, which is why the fix belongs in the comment rather than in either reader's script. The mechanism of the misread is worth the extra sentence, because it is what makes the two-arm form actively misleading rather than merely incomplete: `pgmajfault rises` and `pswpin flat` are two conditions, and only their CONJUNCTION is churn. Both readers selected the arm on the second condition alone -- pswpin flat -- which is exactly what zero-and-zero satisfies. MEASURED, remote: `cargo check -p v1-compiler` Finished, exit 0, against a `-Z definitely-not-a-real-flag` control that exits 101, so a real compiler was reached. `cargo fmt --all --check` exit 0. v1 is frozen with maintenance active; the admission test since 2026-08-20 is PURPOSE -- in support of the v2 self-host program -- and this is a defect repair to a diagnostic the self-host floor emits on every required run. Authority: `gunbc.v1_maintenance_standing` `v1_seed_standing`. cli_run.rs is hand-Rust by declared seed deferral, not an emitted mirror, so no regeneration is involved: `std.realization_schedule` `walk_plan_run_stage_claim_executor_seed_deferral`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The tell is worth more than the specimen: two independent implementers producing the SAME wrong answer The state-space conflation entry names one form -- not-applicable rendered as malformed -- with a recognition rule keyed on an arm downstream of a search that returned `Absent`. The specimen in this PR does not match that shape and is the same class, so this records a second form: A DICHOTOMY STATED OVER A DOMAIN WITH THREE STATES. WHAT MAKES IT WORTH A SEPARATE FORM IS NOT THE SPECIMEN, IT IS THE TELL. A genuine gap produces divergent readings or an error. A dichotomy over a larger domain produces CONVERGENT WRONG ONES, because every reader matches on whichever condition is cheapest to evaluate and the neglected state satisfies it -- here `pswpin flat`, which zero-and-zero also satisfies, so the arm was selected on one of the two conditions whose CONJUNCTION was meant to define it. Receipt: 26 intervals so classified by one reader, 6 by another, neither having compared notes. The convergence is what made it invisible, since agreement reads as confirmation. So the operative rule points the other way from the usual one: when two independent readers of one rule agree on something surprising, suspect THE RULE of being a dichotomy over a larger domain rather than treating the agreement as corroboration. That is the lineage law from the other direction -- agreement is not evidence when the readers share a defect, and here the shared defect is in the thing they both read. Lands beside the comment fix rather than in a separate PR because it is the same finding and the same receipt; separating them would put the rule in one review and its evidence in another. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The tell claimed more than n=2 on one specimen can establish; it is a prompt to re-derive, not a diagnostic Review 56194 (codex) is right and this is conceded rather than argued. The text read that a genuine gap yields divergent readings while a dichotomy over a larger domain yields convergent wrong ones -- stated as canonical guidance, that invites a future reader to INFER a specific modeling defect from evidence that does not uniquely identify it. WHAT THE RECEIPT ACTUALLY SUPPORTS: two readers made the same mistake, once. It does not support the converse direction, and I had no evidence at all for the half about what a genuine gap produces -- that clause was invented to make the contrast symmetrical. CONVERGENCE HAS COMPETING CAUSES THE RECEIPT CANNOT SEPARATE: shared assumptions, a common heuristic, ambiguity in the subject, or one reader having anchored on the other. n=2 on one specimen distinguishes none of them from a defect in the rule. The irony is worth recording rather than smoothing, because it is the same shape I refuted in myself four hours ago: a perfectly agreeing n=2 read as a mechanism. There it was two runs inverted on both axes and it did not replicate at n=34. Here it was two readers agreeing, and I wrote it into the authority document. WHAT SURVIVES, and it is the concrete half codex asked to keep: - the three-state specimen and why the two-arm form misleads - a recognition rule keyed on STRUCTURE rather than on reader behaviour: for every arm of a stated dichotomy, enumerate the domain and check that each arm's conditions are required jointly - the weaker and defensible direction only -- agreement between readers of one rule is not INDEPENDENT evidence about that rule, since the shared input is a shared potential defect, so it licenses re-deriving from the domain and never a conclusion about which cause produced it Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The comment carried the same overclaim this PR corrects in DESIGN, one file away Review 56201 (codex) caught an internal contradiction and is right. The previous commit narrowed the DESIGN entry to say convergence has several possible causes and is a prompt to re-derive rather than a diagnostic -- and left the cli_run.rs comment asserting that a dichotomy over a three-state domain "hands every faithful implementer the same misreading." Two readers do not establish a universal. So the PR corrected the overclaim in the canonical document while shipping it in the source comment, which is worse than either alone: the two artifacts now disagreed, and a reader who found only the comment would take the stronger claim as current. WHAT REPLACES IT is the structural half, which is what was actually established: zero-and-zero satisfies `pswpin flat` and not `pgmajfault rises`, so a reader matching on the cheaper condition alone selects churn for it. That is a fact about the RULE's shape, checkable by reading the rule, and it does not depend on how many readers were surveyed. The sentence now says explicitly that it is an observation about this rule and these two readings, not a prediction about future readers. This is the second time in this PR that the concrete structural claim survived and the generalisation layered on top of it did not. MEASURED, remote: `cargo check -p v1-compiler` Finished, exit 0, against a `-Z nope-not-real` control that exits 101. `cargo fmt --all --check` exit 0.

…and membership is observed beside it rather than folded into it (#9238) * Rebuild the per-entry emission instrument as a .dag entry point DESIGN's Building-&-checks section carries a declared rung drop titled THE MEASUREMENT BANKRUPTCY DELETED A CAPABILITY, NOT ONLY ARTIFACTS. It states its own restoration trigger: a .dag entry point that emits, assembles and compiles one entry and returns the coded-diagnostic population. This is that entry point. It is the INSTRUMENT, not a board -- it produces numbers and stores none. tools.emission_entry_instrument measure_entry_emission runs the spine the deleted probe script ran (gunbc compile --entry -> cssl_assemble -> cargo under --message-format=json) and returns EmissionMeasurement, in which "refused before the emitter ran" has no spelling in the same shape as "emitted with zero diagnostics": an unreached stage is its own variant naming the stage. That is DESIGN's execution-provenance-loss row applied to the instrument that most needed it. extdeps.cargo_diagnostic decodes the rustc coded-diagnostic population -- one member per finding, identity (E-code or the named uncoded state) and location (the primary span, selected by is_primary rather than by position), so two runs can be joined rather than only differenced. A line it cannot read, and an empty stream, refuse with a located cause instead of reporting an empty population. It is a sibling of extdeps.cargo_message rather than a widening of it, which that module's own boundary note asks for. gunbc.emit_diagnostic_observation decodes the emit-stage population from what the CLI already prints. No v1 capability is added: emission is 05_emit territory and the seed is frozen with maintenance active, so this reads the existing surface rather than widening the seed for an instrument's convenience. What makes a prose decode admissible is the cross-check -- the compiler states its own total on the `compiled:` line and again in the renderer's severity summary, and a population disagreeing with either, or the two disagreeing with each other, refuses and names both numbers. NOT A GATE. No workflow invokes it, no phase enrols it, and the exit status reports whether the INSTRUMENT completed, never whether the subject was clean. Evidence: witness claims carry greens and discriminating reds for both decoders and for the carrier's own distinction. Measured at c271b75: the entry compile of the instrument itself is 0 blocking / 138 files emitted, and dag/extdeps/cpu/ampere.dag refuses at emit with 9 blocking / 119 advisory -- re-derived here, not carried from a brief. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Bind the execution subject, and require cargo's terminal message Two corrections from review on #9190, both narrowing. ONE -- THE CARRIER NAMED ITS STAGES AND NOT ITS COMPILER. Splitting the phase states is state-space de-conflation; it is not provenance, and the prose claimed provenance. DESIGN separates the two deliberately: conflation is repaired by splitting states, execution-provenance loss by BINDING A RECEIPT to the value. Without one, the carrier could report the same-looking population from two different compilers -- the same defect one level down from the one the stage split closes. Every outcome that carries a population now carries an EmissionMeasurementSubject: entry, source revision, working-tree standing, and the sha256 of the two binaries actually invoked. It is established BEFORE the emitter runs, and a component that cannot be observed refuses the run rather than being recorded as absent -- an unobserved digest is not the digest of nothing. The one arm without a subject, EmissionSubjectUnestablished, is the one that took no measurement, so an unattributable population has no representation. The identity vocabulary is REUSED, not re-coined: CommitSha from extdeps.git.inspect, Digest from extdeps.crypto.hash. Minting a parallel identity vocabulary inside the instrument built to enforce single authority would be the violation it exists to measure. extdeps.tools.sha256sum gains one operation, DigestFile: CheckFile answers "does this file match this digest", which cannot be used to LEARN one. TWO -- A KILLED BUILD'S PREFIX READ AS A POPULATION. The decoder returned a population from any nonempty parseable prefix, so cargo emitting seventeen messages and then being SIGKILLed reported those seventeen as the answer. That is the truncated-observation-rendered-as-complete failure that created this lane, reproduced inside the instrument built to end it. cargo closes every run it performed with build-finished; a stream without one now refuses and says how far it got. Its `success` member is also now the authority on whether the build was clean, replacing the transport exit status observed beside the stream -- the terminal message is emitted BY the run being measured. Executed: PASS on the truncated-stream red, the terminal-message verdict in both polarities, and both provenance claims (a measurement names its compiler; an unestablished subject carries neither provenance nor population), with an existing green re-run as a regression control. Entry compile of the instrument after both corrections: 0 blocking, 145 files emitted. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The emit population states whether it is the whole population Requirement from smart-ram-730, relayed from deep-ant-102's finding, and it is a level finer than the phase split already in the carrier. THE FINDING, verified here by reading the emitter rather than taken on report: v1.05_emit_rust emit_rust is a sequence of early returns. Measured on the live file there are exactly two, both `return EmitResult { files: [], diagnostics }`, and while the first fires the checks after it NEVER EXECUTE -- two workflow-parameter diagnostics were observed masking eight anonymous-record ones, which had been standing the whole time. So any count taken over emit can be a PREFIX of the truth rather than the truth: not an undercount anyone can bound, but a count that stops silently at whichever earlier check fired. WHY THE EXISTING ARMS DID NOT COVER IT. They distinguish WHICH PHASE the instrument reached. This is finer: within one EmissionMeasured, emit itself may have returned before a later check ran, so two results that both honestly report "emit ran" can differ in whether a check even executed. A consumer reading the first concludes the entry has two blocking diagnostics; it has at least ten. THE DERIVATION IS EXACT, not a guess, which is what makes this a construction rather than a warning. Both early returns write NO FILES, and the CLI prints its `compiled:` line only where a tree was written. So a compile reporting emitted files ran the emit body to its end and its population is Complete; one reporting none is CompletenessUnestablished. That second arm is named for IGNORANCE rather than truncation on purpose: a refusal caused outside emit also lands there, and claiming such a population IS truncated would answer a question this observation cannot answer. Over-stating ignorance is safe; the opposite is the defect. AND THE COUNT NEVER TRAVELS ALONE. The size and the extent are rendered by ONE expression, so a report stating a population size always states the standing of the set it counted -- a separate optional row would let the number travel by itself, which is the entire failure. Executed: PASS on a refused population never reported as complete, a completed one reported as complete (so the extent is a real discriminator and not a constant), no report stating a population without its extent, and the existing carrier claim re-run as a regression control. Entry compile: 0 blocking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The ratchet consumer: an emit-clean frontier over a discovered roster, where an unmeasured subject is neither clean nor suspect tools.emission_entry_instrument answers one question about one entry and stores nothing -- it says so itself, and says gating is a separate decision with a separate argument. This is the consumer half of that sentence, and it is still not that gate: nothing here is enrolled in the required run. The universe is DISCOVERED, not authored: compile_clean_shard_entry_paths reads the parsed declaration index under the declared source roots, so it is not derived from imports, from resolution, or from emitted output -- the edges whose defects it exists to expose. The live specimen is gunbc.auth.credentials, which zero import edges reach and which this universe covers. Debt is carried at IDENTITY grain as admission rows, never as a count. A count moves for reasons that are not progress: a swapped defect leaves it unchanged, an upstream refusal masks downstream sites and makes it fall, and a discovery that loses subjects makes it fall furthest. The third standing is the point. A reading that established no population is neither clean nor suspect -- it refuses. Its discriminating control differs in exactly one field, whether emit reported a tree. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Hash the discovery policy into the roster digest; avoid two corpus-wide name collisions * Give the verdict-entry accessor its consumer: every verdict names its subject * Fix the one blocking diagnostic: a renamed fixture binding missed inside a list literal * Adopt the superseded contract: three-valued outcome, the enrolment wall as a construction, and both holes pinned by execution The clean-frontier ratchet has a hole deep-ant-102 named and I had not: Blocked{A} -> Blocked{A,B} never moves the frontier, so debt grows silently inside already-blocked subjects. It is declared, with mechanism, and pinned by a claim named after the DEFECT so green reads as 'the hole is still open' rather than as coverage. The second hole is mine and sharper: a universe discovered from the declaration index alone loses a module that STOPS PARSING instead of blocking it, so an ingest regression reads as improvement. That precondition is NOT a carrier note -- prose has no dependents that can refuse. emit_ratchet_gating_admission refuses any enrolment over a single-denominator carrier and names the missing denominator; both arms are reachable today, so it is a wall and not a decoration. Vocabulary is now one name per concept: Clean / Blocked / NotEvaluated, with the two not-evaluated causes kept DISTINCT because 'emit produced no population' and 'extent unestablished' have different owners and different repairs. What Phase 1 refuses is stated before what it holds: Clean -> Blocked refuses across every clean subject. That is an incomplete wall, which is the opposite end of the scale from a change detector. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Hole 2's mechanism was wrong: a parse failure under a recognized header refuses LOUDLY I wrote that a module which stops parsing vanishes from the universe. Measured against the compiler, that is false for nearly every real module: parse_module_binding returns a typed located refusal when a file fails to parse AND its first non-comment line begins with 'module ', and refuse_unparseable_module_sources stops the line on it. The silent arm is narrower and real: ModuleBindingUnclassified, which the index's own source documents as a conflation it cannot resolve -- fragments and parse failures land there together. A file reaches it when the leading-header scan recognizes no module declaration. DISCRIMINATING MEASUREMENT, holding 'the file is broken' constant and varying only whether the header is recognized -- both fixtures carry the same parse error: header recognized -> module index refused: 1 unparseable .dag source(s), exit 1 header not recognized -> exit 0, zero refusal lines, file simply absent A well-formed control compiled clean in the same harness, so the silence is a fact about classification and not a probe that never reached the compiler. The pinned claim is renamed to what it actually pins. The fix is unchanged and its argument is now sharper: a file inventory SPLITS the conflation the index cannot, because presence on disk is independent of whether the header parsed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The dual denominator: a file the index cannot classify blocks instead of vanishing Closes hole 2. RatchetUniverse carries a second denominator -- a file inventory via shell.Find.FilesByNameSorted -- and a .dag file present on disk but absent from the declaration index becomes a SUBJECT whose outcome is EmitSubjectBlocked { cause: UnclassifiedByModuleIndex }. THE INVENTORY IS NOT A MORE CAREFUL INDEX. It answers a question the index cannot ask: module_path_index documents its unclassified arm as inseparable, and it is inseparable FROM THE INDEX, because fragments and parse failures look identical there. They do not look identical from the FILE SYSTEM, where presence on disk is independent of whether the header parsed. THE DENOMINATOR IS NOW DERIVED, NOT PASSED. RosterDenominators is no longer a caller-supplied field: the dual value is reachable only by holding a DualUniverse, which is reachable only by supplying an inventory. That closes the fold-time versus mint-time observation from review 55831 and smart-ram-730 independently -- a caller can no longer assert a denominator it has not earned. An unreadable root REFUSES rather than contributing an empty list, because a failure that shrinks the denominator is the exact defect this denominator closes. The hole-2 pin is FLIPPED to its regression control, not deleted: per 4b(4) the climb deletes the production handling it obsoletes, never the evidence that the higher rung is real. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Four stale sentences, not one: the corrected mechanism had not reached the strings that render it Review 55852 caught roster_denominators_text still saying 'a module that stops parsing vanishes' -- the claim the hole-2 correction in the same file had already established as false. Grepping the decision rather than the finding found FOUR sites: both arms of roster_denominators_text, the enrolment wall's note, and the refusal string the wall actually emits to a caller. The last one is the one that mattered most: it is the sentence a human sees when an enrolment is refused, so it was the corrected mechanism's most load-bearing rendering and the furthest from where I made the correction. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * A zero-file tree is not a clean entry: do not rest the load-bearing arm on the seed's printing discipline deep-ant-102 relayed a finding from bold-stag-236, who owns the producer: EmittedFileCount does not ASSERT the emitted/not-written distinction. FilesNotWritten is what the ABSENCE of the compiler's 'compiled:' summary line decodes to, and the compiler prints that line only when a tree was written. The distinction is inherited from the producer's printing discipline, which nothing pins. That lands hardest here. NotEvaluated is the load-bearing row of this ratchet -- an upstream refusal turning blockers into ABSENCE, with absence reading as zero, is the failure it exists to prevent. Populated only from FilesNotWritten, the row that makes the ratchet honest would rest on an unpinned convention in a frozen seed, and the failure would be exactly the one it guards: a run that emitted nothing reported as a run that emitted zero, and a subject reading CLEAN when it was never evaluated. Verified against the code rather than assumed: FilesEmitted { count: 0 } did derive EmitPopulationComplete and therefore Clean. So the derivation no longer depends on that convention for the dangerous direction. A zero-file tree is EmittedNothing, a third distinct NotEvaluated cause, so the hypothesised misprint lands in NotEvaluated and refuses either way. The convention still decides WHICH cause is reported -- a rendering difference rather than a verdict difference -- and the note says so. NOT CLOSED, and named: pinning the printing discipline itself needs a probe on a path that emits no tree, asserting the summary line is ABSENT rather than present-with-zero. That belongs beside the decoder, not inside this ratchet. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Restore the standing section my own block replacement deleted The dual-denominator edit replaced a range running from the fold to the enrolment wall, and the whole standing section lived between those two anchors: ratchet_failing_verdicts, ratchet_failing_rows, EmitRatchetStanding, emit_ratchet_standing and emit_ratchet_standing_text were deleted wholesale by an edit that named neither of them. Caught by the compiler, not by review or by reading the diff -- and the tell was 'function map not found in scope', a builtin, which is what a cascade looks like when a module loses declarations that later ones depend on. The nine errors it reported were one deletion, not nine defects. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Delete the FIPS 180-4 fork in sha256sum: consume the citation extdeps.crypto.hash owns review 55859, REQUEST_CHANGES. sha256sum.dag re-minted sha256_algorithm_authority pointing at FIPS 180-4, forking the citation owned by extdeps.crypto.hash extdeps_external_authority_anchor. review 50411 had already refused the identical fork in the sibling sha512sum, whose note records the consume rule. THE FORK HAD ALREADY DRIFTED, which is why it is deleted rather than reconciled: the local row read .../180-4/final, the owning row reads .../180-4/upd1/final. Two spellings of one citation had begun to disagree about which revision of the standard is cited -- the decay 3 predicts, and the reason a second name for one fact is a correctness concern and not a style one. PROVENANCE, STATED BECAUSE IT CHANGES WHO OWES WHAT: the forked row is PRE-EXISTING ON MAIN, not introduced by #9190 -- that PR added DigestFile and the Digest-typed read only. This is debt the stack touched rather than authored. It is cleared here anyway: it is a real fork with a documented precedent refusing it, and provenance is not a defence for leaving one standing. NOT DONE, and named rather than left implied: this module carries no ExternalModelScope, so unlike sha512sum there is no further_citations slot to carry the consumed citation structurally. Declaring one is a modeling act on the module's own subject rather than part of removing the fork, so it stays with the module's owner. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The claim asserting the refusal string went stale when I corrected the string Renaming 'module inventory' to 'file inventory' across the corrected prose left the one assertion that READS that string still grepping the old wording, so a_single_denominator_carrier_refuses_enrolment_and_names_what_is_missing went red. This is the same class as the four stale sentences review 55852 found, one turn later and caught by execution instead of by a reviewer -- which is the argument for asserting the string rather than the shape: a claim that only checked 'it refused' would have stayed green through a rename that broke what the refusal tells a human. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * The printing-discipline probe pins one path, not the compiler: correct the remedy's stated size bold-stag-236, who owns the decoder, corrected the note I wrote naming the probe that would pin the compiler's printing discipline. A probe on a path that emits no tree establishes a property of THAT PATH, and v1 has more than one such path, so it raises confidence without closing the class. What closes it is the summary line emitted from a single site that cannot run without a tree -- present-with-zero having no PRODUCER rather than no observed instance. That is a v1 change and blocked under the seed freeze, so it is the class's next-rung trigger rather than work someone is declining to do. Recorded because a remedy described as bigger than it is becomes coverage nobody re-examines, which is the same failure as an inflated rung one level over. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Subject identity for the emission ratchet: a key of root, kind and resolution policy, with membership observed beside it rather than folded into it * A measurement over a subject whose boundary did not hold is not a measurement of that subject * A sixth copy of string-list membership, differing only in parameter name, is the fork the whole-corpus prep resolves against * roster_identity had two declarers: a per-entry compile sees one, the floor sees both, so the collision was invisible to the check an author runs * The witness declares imports, so its disposition type must be imported too * A keys() accessor has to answer something for the refused arm, and the only answer available launders the refusal * The enrolment claim still asserted the pre-rename wording, so it went red on the branch where only the carrier had been swept * Answer the dual-denominator question in the carrier, and decline the witness that would decorate it Review asked, reasonably, whether a subject key is stable under a file the declaration index cannot classify -- the case gunbc#9231 made block instead of vanish -- and said it would look for that witness first. THE ANSWER IS STRUCTURAL AND IT IS NOW IN THE CARRIER: the key's root is a SOURCE ROOT, not a file. No file's classification can add a key, remove one, or change one, because no key names a file -- the matrix is roots times kinds and both factors are closed and authored. The two denominators cannot disagree at this grain. AND NO WITNESS IS AUTHORED FOR IT, DELIBERATELY. §4b says to ask whether a check's RED is authorable BEFORE writing the check. There is no input by which a classification outcome could reach a key, so the claim would be permanently green BY CONSTRUCTION -- a decoration, and worse than absent, because it would be cited as coverage for an interaction it never tested. Writing it would have satisfied the review and weakened the evidence. Where the denominators DO matter is one layer out, in the frontier whose roster is keyed by ENTRY PATH and where a file is exactly what can vanish. That is hole 2, and it is closed there -- in the carrier that can express the failure. Entry compiles 0 blocking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * WITHDRAWN: the three "blocking diagnostics on main" in the previous commit message were my stale compiler The commit message on f495de5 reports that main carries three blocking emit diagnostics in `extdeps.filesystem.filesystem_io` (`Read`/`Delete`/`List`, file transport output keys with no modeled channel), landed by #9265. THAT IS FALSE and this commit withdraws it. No carrier was touched by the claim -- it lived only in that message and in one message to a peer, both corrected. RE-MEASURED, not merely conceded. Rebuilt the compiler from THIS tree, which contains 37bb097, and compiled the same entry: 0 blocking. The binary I used originally was tree-built but from a1856a5, and `git merge-base --is-ancestor 37bb097 a1856a5` is FALSE -- so its source predated the change by construction, not by clock. WHAT #9265 ACTUALLY DID: it ADDED `read_success`, `delete_success`, `list_success` and `entries` to the modeled-channel set. It is the fix. My compiler was old enough to be the last version that refused them, and it reported main as broken in exactly the way it had just been repaired. WHY THIS IS WORTH A COMMIT RATHER THAN A QUIET DELETION. The output was not obviously wrong: one specific, typed, correctly-located semantic diagnostic naming three real output keys in a real module -- indistinguishable from a true finding, and I nearly queued it for a transport owner who would have spent a morning fixing something that already worked. A stale instrument does not announce itself; it produces a plausible measurement of a tree it has never seen. The instrument's age is a property of the SOURCE it was built from, and that is checkable (`merge-base --is-ancestor`) where a file timestamp is not -- my binary's mtime was LATER than the commit it lacked. THE STANDING CHANGE: a compile result about main is only evidence if the compiler contains main. I check that with merge-base before reporting a diagnostic as a finding, not after.
