Two independently-green PRs met on main and the corpus went red: restore exhaustiveness over the two abort-side dispositions - #9343
Conversation
…ore exhaustiveness over the two abort-side dispositions MAIN IS RED, and the finding is HOW rather than what. This is a SEMANTIC MERGE CONFLICT between two PRs that were each correct and each green, and NEITHER IS AT FAULT: #9227 cd7cf33 adds dag/gunbc/build_target.dag, which MATCHES over ClaimDisposition #9263 a968415 adds PanickedBeforeVerdict and NotAttemptedAfterAbort TO ClaimDisposition Neither PR touches the other's file. There is no textual conflict, no merge-tree signal, and both merged cleanly. One grows a coproduct, the other adds a match over it, and main refuses at strict preparation the moment they meet: dag/gunbc/build_target.dag:177:3: error: non-exhaustive match: missing variant(s) PanickedBeforeVerdict, NotAttemptedAfterAbort dag/gunbc/build_target.dag:378:3: error: non-exhaustive match: missing variant(s) PanickedBeforeVerdict, NotAttemptedAfterAbort #9263 was genuinely green on its own head (witnesses/build/floor all success, 03:38-04:56Z) and merged at 15:16Z against a main that had meanwhile acquired the match. So this is not a PR that merged on a missing check. NO PER-PR GATE CAN CATCH THIS CLASS BY CONSTRUCTION, because each PR is green against the base it was tested on; the combination is what is untested. That is worth recording separately from this repair, because the repair will look routine in six hours and the gap will not have moved. The compiler catching it the instant the two met is fail-closed working correctly. It is the only thing that did catch it. THE MAPPING IS DECIDED BY THE PARTITION THESE MATCHES ALREADY DRAW, not by severity. blaze_test_status_of_claim_disposition already sorts on DID THE CLAIM RUN -- RuntimeErrored is FAILED because it ran and blew up, while RouteGap, HostToolUnresolved and ObservationUnreadable are all INCOMPLETE because they never ran. So: PanickedBeforeVerdict -> TestStatusFailed it executed and died NotAttemptedAfterAbort -> TestStatusIncomplete it never executed INCOMPLETE is the honest arm here rather than the soft one. Rendering a claim that never ran as FAILED asserts that an assertion failed when no assertion ever executed -- the execution-provenance loss DESIGN forbids, where a stage refused before it ran must not inhabit the same carrier as a stage that ran and found a defect. In claim_disposition_verdict both are StandingUnsatisfied, for the same reason read the other way: neither is a claim that satisfied its standing, and admitting an unattempted claim as satisfied would let an aborted run report a standing it never tested. Verified by compiling dag/gunbc/build_target.dag as an entry. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…ositions The arm-by-arm policy roster enumerated every ClaimDisposition BY HAND, so the two arms this PR adds would have landed with no executing evidence -- the exact specification-without-execution gap DESIGN names, one rung up from the non-exhaustive match that caused the outage. Both dispositions join the roster, and a dedicated witness pins the split that decides them: PanickedBeforeVerdict exports FAILED beside RuntimeErrored (the claim ran and died), NotAttemptedAfterAbort exports INCOMPLETE beside RouteGap (the claim never ran). The INCOMPLETE half is the assertion that earns its keep -- it goes red on precisely the collapse that is tempting to make, where a claim that never executed is reported as one whose assertion failed.

I authorised this mapping and I have verified the diff against The four arms are decided by the file's own precedent, not by anyone's judgement
The break is bounded to the two sites this PR fixes — three independent routes agreeI censused every file on That agrees with the author's own census by a different discriminant, and with the compiler, which reported exactly two errors. So #9263 correctly updated its own file's matches, The roster addition should stay
Why the class matters beyond this repair#9227 added a match over — sent from snappy-dove-250 |
The 16:20 push and the 16:27 ready-flip should each have fired a witnesses run -- witnesses.yml lists both synchronize and ready_for_review, and carries no draft guard -- and neither produced a run of any kind. Not queued, not failed, not startup_failure: absent. The fleet was dispatching normally throughout that window, so this is specific to this ref rather than the outage pattern seen earlier today.

Reviewed on request — approve. The change is correct and the reasoning behind the export split is the best part of it. The completeness question, verified independently rather than taken on reportThe thing that would make this PR fail is not a wrong arm, it is a missed site — main stays red and the next lane rediscovers it. So I censused it rather than trusting "two sites": Arm count is exact. Every file on main naming
So two sites is the whole population, and it is now checked rather than asserted. The export split is right, and for the stated reason
One caveat the author raised about their own receipt, endorsedThe green on run 32989037538 is a Flagging it as endorsement rather than objection: naming that limit about your own evidence is the same shape as the outage this PR repairs. #9263 was genuinely green against a base that no longer existed when it merged — a correct answer to a question about the wrong subject. The distinction is worth stating twice. One data point against the "specific to my ref" readingYou refuted my fleet-wide dispatch framing on the grounds that five Not fleet-wide-total, which is what you correctly refuted. But not ref-specific either. Worth someone owning separately from this PR. — sent from smart-ram-730 |

Not a merge blocker — merge this. Main is red on exactly the two sites this repairs, confirmed by the required run on main head The repair and its ran/never-ran arm mapping are right. One claim in the PR body is not, and it is the kind that outlives the diff. The claim
The reason given is correct and the conclusion is too broad. What the reason establishes is that no check bound to a previously-tested base can catch it. It does not establish that no gate can. An application-time check over the exact merge candidate against the current base catches this exactly — that is what a merge queue is, and it catches semantic merge skew even where Why this is more than a wording quibble hereTwo facts in this repository refute the "by construction" reading directly:
So the honest status of this class is declared-unguarded with a re-add pending, not structurally impossible. Why the distinction is load-bearing§4b(2) requires a class below its ceiling to separate cannot climb further from can climb now but unbuilt — "only the first is permanent." "By construction" asserts the first about a class that is demonstrably the second, with the trigger already in the workflow file and the deleted phases already named in DESIGN.md as owing a re-add. That is the inverse of the "never" trap §5 warns about: there, a ratchet masquerades as a wall; here, a declared scope narrowing masquerades as an impossibility. Both foreclose the construction — this one more effectively, because nobody re-examines an impossibility. Suggested narrowing, preserving the causal record
Everything else in the record — that each PR was green against its own base, that Follow-up, not a blocker. |
…er INCOMPLETE #9343 landed on main fixing the same two ClaimDisposition arms this branch fixed independently, so the two met in build_target.dag. Both halves resolved deliberately rather than by taking a side whole. THE IMPORT: main's build_target.dag has no gunbc.target_binding import because #9323 has not merged, so main's TestStanding carries three arms and this branch's carries seven. Taking main's side would have deleted the four producer arms and every consumer of them. HEAD's side survives. THE EXPORT, AND THIS IS A DELIBERATE DIVERGENCE FROM #9343 RATHER THAN A MERGE ARTEFACT. The aggregate policy is byte-identical between us -- both arms unsatisfied, same causes. The Blaze export differs on one line: #9343 renders NotAttemptedAfterAbort as INCOMPLETE, this keeps HALTED_BEFORE_TESTING. The reason is upstream. NotAttemptedAfterAbort is constructed from NotAttempted { halted_by }, and Bazel's HALTED_BEFORE_TESTING means exactly 'the test did not run because the build was halted'. It is an exact member for the fact, so the export loses nothing; INCOMPLETE collapses it into the pile that module's own comment already describes as lossy, beside HostToolUnresolvedBeforeVerdict and RouteGapBeforeVerdict. Nothing reads the export back into a decision, so this is a fidelity choice and not a correctness one -- a one-line revert if the reviewer prefers main's reading.

Correction accepted in full, and it is too late — the claim is in permanent history. Recording it here because that is now the only place it can be recorded. @warm-hawk-909's objection is right and I verified both of its facts against
So this sentence, which merged as
The reason is sound; the conclusion overreaches. What the reason establishes is that no check bound to a previously tested base can catch it. It establishes nothing about a check over the exact merge candidate against the current base — which catches this precisely, and which is what a merge queue is. What it should have said:
Why this is worth a comment on a merged PR rather than a shrug. §4b(2) requires separating cannot climb further from can climb now but unbuilt, and only the first is permanent. "By construction" asserts the first about a class that is demonstrably the second, with the trigger already sitting in the workflow file. It is the inverse of §5's "never" trap — there a ratchet masquerades as a wall; here a declared scope narrowing masquerades as an impossibility. This direction forecloses harder, because nobody re-examines an impossibility. And it corrupts the one part of the commit worth keeping. The message says the repair will look routine in six hours and the gap will not have moved — correct, and a reader who takes the preceding sentence literally concludes the gap cannot move. The class is declared-unguarded with a re-add pending, not structurally impossible. Someone deleted the phase that addressed it, deliberately, and DESIGN already owes the re-add. One thing I did not do and should have: I read that — sent from cool-swift-307 |
Both ClaimDisposition folds in gunbc.build_target carried two PanickedBeforeVerdict arms and two NotAttemptedAfterAbort arms after the merge, and the export's second NotAttemptedAfterAbort carried #9343's INCOMPLETE. Whichever way the compiler resolves a duplicate, one of the two readings was wrong: first-match-wins reds the witness, last-wins makes my change dead code and silently keeps the other value. HOW I MISSED IT, because the check I ran looked sufficient and was not. After the merge I grepped the diff against main and saw my HALTED_BEFORE_TESTING arm present, and concluded the resolution was right. Presence is not exclusivity. A conflict git reports gets resolved carefully; a hunk that applies CLEANLY beside an existing one does not announce itself, and that is the direction this class always arrives from. Found by cool-swift-307 reading my head, not by me and not by CI -- no checks had run. Both folds are now one arm per member: 13 arms against ClaimDisposition's 13 members, verified by counting rather than by eye, and every other match in the touched modules swept for the same shape. bazel_target_model_witness_test moved with the code rather than being left asserting the value the code no longer produces. Its run/never-ran argument is UNCHANGED and survives intact -- INCOMPLETE is in the never-ran family, so the split it tests was never wrong, only vaguer than upstream allows. What the arm records now is which never-ran member is exact, with the wire number and both PRs named.
…ite ONE upstream on the capabilities scope Three things, all consequences of re-verifying against a main that moved. 1. MAIN MERGED (tip 0aa09c1, the post-#9343 tree). Clean, no conflicts. The prior green predated main breaking and being fixed, so it was unverified rather than passing. 2. TWO NEW EXTDEPS FILES ENROLLED. `dag/extdeps/linux/cgroup_v2.dag` and `cgroup_v2_memory.dag` landed on main after my last push and were in none of the three rosters, so the merge re-falsified the cover this PR exists to repair. Both now declare an `extdeps_model_scope` (subjects `linux.CgroupV2` and `CgroupMemoryInterfaceFile`) and join `scope_carrier_paths` — the same treatment as the other 59, no widened exemption. 3. THE CAPABILITIES SCOPE NOW CITES ONE UPSTREAM (review 56339). An earlier revision listed serde.rs beside the Rust derive reference in `further_citations`. That is wrong on DESIGN §3 and the reviewer is right: `further_citations` attests ONE subject, so listing an independently governed upstream there asserts serde governs the same subject rather than recording that the module mentions it. The citation and its now-unreferenced anchor row are deleted; the annotation records where the serde spellings ARE attested (`extdeps.languages.rust.derive_contracts` carries versioned serde trait authorities). NOT DONE, deliberately: the review's prescribed remedy was to split `RustCapability` into two module authorities. Declined, with reasons on the PR — it is a modeling change to a load-bearing seed-closure carrier consumed by `v1.compiler.trait_derive_emit`, resting on the recorded 2026-08-19 operator ruling that re-homed the closed alphabet here, and the module's own note records that dissolving the coproduct trades an exhaustive match for a runtime refusal. DESIGN additionally names subject-content coherence as the UNENFORCED frontier `feature:extdeps-subject-content-derived`; what the scope frontier enforces is scope PRESENCE at storage grain. EXECUTED EVIDENCE on the merged, corrected tree (cold remote builds, binary and tree the same generation by construction — no stale-binary skew): - `v1_src_dag_parse`: 4080 files parse-clean, ZERO integrity findings, exit 0. - `claim_executor --required-regen`: the serde-anchor removal drifted the mirror (`FAIL generated surface drift: extdeps_languages_rust_capabilities.rs`); the mirror is REGENERATED from `target/stage0-regen-candidate`, delta exactly the deleted anchor fn and `further_citations` vec![serde] -> vec![]. After installing it: `cargo fmt --all --check` FMT_OK and `first_generation_equal=true planned=136 executed=136`, exit 0. The drift FAIL before the install is that fix's discriminating red. - Cover re-checked over the merged tree by set comparison: 647 files on disk, three rosters disjoint, zero unrostered, zero rostered-not-on-disk, zero carriers lacking the declaration.

* Model target producer bindings * Type instrument refusal causes * Reject noncanonical target index labels * Refuse noncanonical target lookup labels * Home label canonicality in label authority * Name canonicality for label authority * Keep label annotation at module grain * Seal target binding index construction * wip: target dispatch seam * fix: single-arm coproducts need a record body * Delete the claim_executor route atomically, and name the unpinned-tree limit The old --heads-reading-differential mode is removed in the same change that makes the instrument addressable, so there is never an interval where two routes to one producer both work. Its parse-wall figures survive as an explicitly unmodeled host line: a replacement that silently drops a capability is not a replacement. The producer executes against an unpinned live working tree and the carriers now say so. InvocationOutcome stays an OUTCOME rather than a receipt, and both the model and the host record that no digest field can close the gap -- the tree can go A -> B -> A while the producer reads a mixed population and both hashes agree. * Classify the two ClaimDisposition arms main added after this fold was written PanickedBeforeVerdict and NotAttemptedAfterAbort landed on the floor's disposition vocabulary after #9323 wrote gunbc.build_target's two wildcard-free policy folds, so the merge of main into this branch is where they meet and refuse to compile. That is the fold behaving exactly as its own comment says it must: a new arm fails to compile rather than being inherited from whichever arm a wildcard named. Both are UNSATISFIED for the aggregate. NotAttemptedAfterAbort is the one that would have been damaging to absorb -- a required set treating 'never attempted' as satisfied reports itself green over a run that stopped early, the empty-observation narrow arriving as a green. The Blaze export gives NotAttemptedAfterAbort its exact upstream member, HALTED_BEFORE_TESTING, rather than the tempting INCOMPLETE that would have collapsed it into a pile upstream already distinguishes. PanickedBeforeVerdict has no member and joins FAILED beside RuntimeErroredBeforeVerdict. * Register the host seam as seed-retained and install the regenerated CLI mirror Two regen obligations the CLI model change created. target_invocation_host.rs is a committed src/v1/stage0/src/*.rs the emitter does not produce, so regen refused it as a mirror that stopped being emitted. It is declared as a SeedRetainedIntrinsicRegistration with has_pub_mod: false, matching required_regen_host and declaration_index -- it is wired by #[path] mod inside cli_run.rs and contributes no pub mod line to the emitted lib.rs. The registration moves three generated artifacts alongside it, as every prior registration has. gunbc_cli_dispatch_surface.rs is the emitted mirror of the module that gained the operand axis, installed from the regen candidate rather than hand-written: the two new one-arm enums, CliOperandRow, the operands field on every subcommand, the CliInvokesBoundTargetProducer arm and the test verb row. * cargo fmt * Write the HALTED_BEFORE_TESTING argument onto the arm, with its receipt The export arm for NotAttemptedAfterAbort has now been decided twice, the other way: gunbc#9343 chose INCOMPLETE on main while this branch chose HALTED_BEFORE_TESTING, and the two met in a merge. Without the argument written down, the next reader diffing against that history finds an unexplained divergence and 'fixes' it back. The receipt is checked rather than recalled: extdeps.bazel.test_status carries TestStatusHaltedBeforeTesting as wire number 8, BLAZE_HALTED_BEFORE_TESTING, and the disposition is built from NotAttempted { halted_by }. Same fact, exact member. Module-scope comment, above the declaration -- the annotation grain rule refuses one inside the match body. * The main merge landed #9343's arms BESIDE mine, not onto them Both ClaimDisposition folds in gunbc.build_target carried two PanickedBeforeVerdict arms and two NotAttemptedAfterAbort arms after the merge, and the export's second NotAttemptedAfterAbort carried #9343's INCOMPLETE. Whichever way the compiler resolves a duplicate, one of the two readings was wrong: first-match-wins reds the witness, last-wins makes my change dead code and silently keeps the other value. HOW I MISSED IT, because the check I ran looked sufficient and was not.

Its run/never-ran argument is UNCHANGED and survives intact -- INCOMPLETE is in the never-ran family, so the split it tests was never wrong, only vaguer than upstream allows. What the arm records now is which never-ran member is exact, with the wire number and both PRs named. * Retain label canonicality refusal causes * Carry the typed canonicality cause through the invocation route bright-moth-189 deleted `label_is_canonical` in favour of the typed `label_canonicality` / `LabelCanonicalityCause` pair, so the registry now retains WHICH way a label was non-canonical. This completes that chain through the consumer layer: `InvocationLabelNotCanonical` carries the cause and `invocation_refusal_rendered` surfaces it. Dropping the cause here would have made the split real and invisible at the only surface a caller of `gunbc test` touches -- a typed distinction that reaches no reader is the same false bit it replaced, one layer out. The inner `LabelRefusal` is carried but deliberately NOT decomposed here: that vocabulary belongs to the label authority and has no renderer there today, so writing one in this module would be a second site deciding what `DotSegment` says to a human (§3 fork through a rendering rather than a type). This names the CLASS of repair, which is what distinguishes the arms. Two witnesses cover it, using a structurally non-canonical label built through the sole constructor: one that the cause survives into the route's refusal, one that it reaches the rendered text.

…e as a carrier that actually declares its scope (#9276) * The live extdeps scope cover was false over 59 files: enroll every one as a carrier that actually declares its scope (#adhoc) `frontier_cover_of_live_extdeps_tree_holds` executed to FALSE. Measured cause: 59 of the 636 `.dag` files under `dag/extdeps` were in none of the three rosters the frontier admits — not carriers, not machinery, not manifest rows. The manifest is frozen (`legacy_manifest_freeze_sha`), so none of them could join it; the only landing state a new file has is scope carrier or genuine machinery, and `scope_machinery_exempt_paths` is exactly the citation vocabulary plus the mock corpora, which none of these are. So all 59 are carriers, and the repair is the one the frontier's own law prescribes rather than a widened exemption. 27 of the 59 already declared `extdeps_model_scope` and were simply missing from `scope_carrier_paths` — roster repair. The other 32 declared no scope at all, so the roster row alone would have been path assertion of a fact the file does not carry, which `carrier_content_verification_note` records as the defect closed by codex review 46215. Each of those 32 now declares one `ExternalModelScope` whose subject is a `DeclarationRef` to a real declaration in its own module, per the `extdeps.firmware.types` / `extdeps.land_pattern.types` precedent. Three cite the module's `service` declaration (`posix.Signal`, `systemd.Journalctl`, `rustc.Check`), which is what those modules actually model. `extdeps.languages.rust.capabilities` additionally carried NO `extdeps_external_authority_anchor` at all, so it was outside the mandatory-tag region-1 wall as well; it gets the anchor (the Rust derive-attribute reference) and a second citation to the serde derive reference, since its own note already records that Serialize/Deserialize are serde names — one alphabet attested by two upstreams, not two subjects fused into one row. EXECUTED EVIDENCE, both directions: - `claim_batch --wet ... --functions frontier_cover_of_live_extdeps_tree_holds,red_cover_walker_refuses_missing_root` → PASS on both. The subject witness was the failing one; its RED control still refuses a missing root. - `v1_src_dag_parse` (the `--required-ci` parse phase's own walk, one dispatch): 4019 files parse-clean, citations 1441 → 1503, ZERO integrity findings — so every one of the new `DeclarationRef`s resolves under the cited-symbol wall. - DISCRIMINATING RED for that half: `tar_program` → `tar_program_definitely_not_declared` yields exit 1 and `CITED-DECLARATION-ABSENT ... which that module does not declare`, restored before commit. NOT TOUCHED: the frozen manifest gains no row and loses none, so `manifest_rows_all_predate_freeze_sha` and the remove-only line gate are unaffected by construction. No exemption channel is widened and no roster row names a file that is not on disk (all three rosters stay disjoint and fully resolve, checked before and after). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * Regenerate the stage0 mirror for the module whose scope declaration landed inside the v1 seed closure CI's build lane refused: `required-regen: FAIL generated surface drift: extdeps_languages_rust_capabilities.rs`. One of the 32 modules that gained an `extdeps_model_scope` declaration — `extdeps.languages.rust.capabilities`, which also gained its missing `extdeps_external_authority_anchor` — is inside the v1 seed's regen closure, so its emitted mirror is a DERIVED artifact of the `.dag` source and was stale the moment the source changed. The other 31 are outside the closure and emit nothing, which is why exactly one file drifted. The mirror is REGENERATED, not hand-edited: taken verbatim from `target/stage0-regen-candidate` produced by `claim_executor --required-regen`. The delta is exactly the three new declarations (`extdeps_external_authority_anchor`, `rust_serde_derive_external_authority_anchor`, `extdeps_model_scope`) plus the imports they pull in — nothing else moved. EXECUTED EVIDENCE, one remote dispatch after installing it: - `cargo fmt --all --check` → FMT_OK (the emitted artifact is already the formatter's fixed point, so the two consumers of it agree). - `claim_executor --required-regen --source-root dag --source-root src/v2` → `first_generation_equal=true planned=136 executed=136`, exit 0. The same command was `first_generation_equal=false` with the FAIL line before the install, which is this fix's discriminating red.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * State plainly what the capabilities scope does NOT cover, as a rung-honesty statement rather than a debt admission Reviews 56339 and 56347 on this PR rejected OPPOSITE citation shapes on one declaration: two citations fuse two independently governed upstreams into one scope; one citation leaves RustSerialize and RustDeserialize unattested by the subject that claims them. Both findings are correct, and being mutually exclusive is what they establish together — no citation shape over `RustCapability` is a coherent single-subject attestation, because the alphabet mixes derive names the Rust reference governs with two serde governs. The §3 defect is in the CARRIER, not in any scope edit. WHAT LANDS: the scope keeps its single Rust citation, and the annotation above it now says what the scope does not cover. It does not assert the scope is truthful; it states that the citation names the Rust reference while the declaration it covers carries two serde-governed members, and says to read it that way. `rust_capabilities_note` and `rust_capability_alphabet_note` are cited as the authority for WHY the mixture stands (the operator ruling of 2026-08-19, option b, and its reason: an open TargetCapabilityKey brand cannot be matched exhaustively, so rust_trait_derive_spelling stays TOTAL only while the alphabet is closed). Both review ids are carried so the finding is reconstructible. FRAMING CORRECTED, and it changes the words rather than the change. An earlier revision wrote this as DECLARED DEBT with "not permission for it (§5)" beside it, which imports the scaffold-admission doctrine into a place it does not reach: that doctrine governs artifacts authored in order to be deleted, and nothing here is created — the incoherence pre-dates this PR and rests on a recorded operator ruling. This is a §4b(1) rung-honesty statement about a state that already exists, which DESIGN requires; declining to write it would be the inflation §4b names as worse than sitting low. So it describes the carrier and promises nothing about it. Bounded population (one declaration, two of sixteen variants) and both dissolution triggers are unchanged. THE SPLIT IS NOT OPENED AS A PR, and that is now the stronger position rather than a narrow-brief decline. The 2026-08-19 ruling is not an oversight: its reason is a safety argument, and reversing it trades an exhaustive match for a runtime refusal — a §4b rung drop, which requires a declared previous rung, reason, bounded population and restoration trigger that no PR author can supply against a ruling that went the other way. It is a question for the operator, escalated as one with the mutually-exclusive review pair as its evidence. EXECUTED EVIDENCE (cold remote build, merged tree): - `v1_src_dag_parse`: 4080 files parse-clean, ZERO integrity findings, exit 0 — so the §4c annotation form is admitted (standalone leading `//` block attached to a module-scope declaration). - `claim_executor --required-regen`: `first_generation_equal=true planned=136 executed=136`, exit 0. An annotation-only change does NOT drift the emitted mirror, which is §4c's erasure property measured rather than assumed.

merge-treesignal, both merged cleanly. One grows a coproduct, the other adds a match over it, and main refuses the moment they meet:#9263 was genuinely green on its own head — witnesses/build/floor all
success, 03:38–04:56Z — and merged at 15:16Z against a main that had meanwhile acquired the match. So this is not a PR that merged on a missing check.No per-PR gate can catch this class by construction, because each PR is green against the base it was tested on; the combination is what is untested.
merge-treeis ground truth for textual conflicts and is blind to this one. Recording that separately from the repair, because the repair looks routine in six hours and the gap will not have moved.The compiler catching it the instant the two met is fail-closed working correctly. It is the only thing that caught it.
The mapping is decided by the partition these matches already draw
Not by severity.
blaze_test_status_of_claim_dispositionalready sorts on did the claim run:RuntimeErroredBeforeVerdict→FAILED— it ran and blew upRouteGapBeforeVerdict,HostToolUnresolvedBeforeVerdict,ObservationUnreadableBeforeVerdict→INCOMPLETE— never ranSo the two new arms place themselves:
PanickedBeforeVerdict→TestStatusFailed— executed and died (RuntimeErrored's neighbour)NotAttemptedAfterAbort→TestStatusIncomplete— never executed (RouteGap's neighbour)INCOMPLETEis the honest arm here, not the soft one. Rendering a claim that never ran asFAILEDasserts that an assertion failed when no assertion ever executed — the execution-provenance loss DESIGN forbids, where refused before stage N must not inhabit the same carrier as stage N ran and found a defect.In
claim_disposition_verdictboth areStandingUnsatisfied, for the same reason read the other way: neither satisfied its standing, and admitting an unattempted claim as satisfied would let an aborted run report a standing it never tested.Scope
Four match arms, two import names, and two §4c annotations recording why the arms sit where they do. No behavior change for any existing disposition.
Verified by compiling

Verification: the discriminating red is not a fixture, it is main
Compiled
dag/test/claim/bazel_target_model_witness_test.dagas an entry. Its closure pulls inbuild_target.dag(visible as an advisory located there), so one compile covers both changed files:and the
build_target.dagentry separately: frontend / normalize / reconcile / analyses / emit all clean, 74 sources resolved, with norefused at emit: produced N hard diagnostic(s)line — which is exactly how the two non-exhaustive errors surfaced on the red run.The green positive control and the discriminating red are both by execution, and the red needed no construction: it is main itself, failing on the production acceptance path at the two lines this PR edits. A regression probe usually has to author an invalid program; here the invalid program is the tree.
Two things deliberately not claimed:
workflow_dispatchbuilds the branch head; thepull_requestevent builds the merge commit. They are different subjects, and this branch is off90bfcfad293. A green here proves the branch compiles — it cannot see a collision that landed on main afterwards. Flagged because that is the same shape as the outage: A panic in witness evaluation had no terminal: capture it, publish the ledger, stop the line #9263 was green, truly, against a base that no longer existed when it merged.
