Anchor the two programs in .dag plan carriers bound to their mechanisms by symbol

Two plan carriers: the v2 self-host program and the import/namespace program

Both anchors the operator asked for, as .dag Plan carriers. No .md in this PR — the markdown is generated from typed blocks, so there is no second authority to drift.

carrier	slug
gunbc.plans.v2_corpus_self_host	v2-corpus-self-host
gunbc.plans.import_namespace_program	import-namespace-program
gunbc.compiler_frontend_program_interlock	(the cross-program ruling)

Both plans are registered in plan_registry_batch_g and carry a retirement condition. Every DeclarationRef was verified to resolve before authoring, so the ingestion-time citation wall re-checks them on every required run.

The sequencing ruling is carried ONCE, not restated

Operator ruling 2026-08-26 answered the question both plans had open, and the answer was that the question was posed at the wrong grain: neither program blocks the other whole. Self-host's proof envelope blocks the first namespace semantic wave; namespace completion blocks self-host's irreversible retirement step. A braid, not a total order.

Per the ruling's own instruction, that relation lives in gunbc.compiler_frontend_program_interlock and both plans cite it. milestone_prerequisites is a total function over a closed milestone variant, so a newly declared milestone fails to compile until its prerequisites are stated rather than silently having none — construction rather than validation.

Its executable consequence: the namespace plan's disclosed "no CI mechanism" gap is now a blocker, gating Step 1 by name. Preparatory work is explicitly unaffected.

Corrections taken from review

Three from the operator's exact-head review, plus three from peer audits:

• The ratchet sentence said counts are "display only and decide nothing". The ratchet owner measured that as literally false, and their wording replaces mine: no cardinality is a gate oracle, but emptiness decides whether a population is inhabited or evaluated — including the distinction between an empty roster and an identified roster with no failures. The roster digest, not its count, is its identity.
• The status block claimed "no transcribed instrument output" while the next section explicitly carries a transcription. It no longer claims both states.
• This body was stale — it still said DRAFT with half the content unwritten. Fixed here.
• S1 asserted a PR's open/closed state and got it wrong in the worst direction: it said One silence, two owners: a subject nobody asked about is not a subject the instrument failed on #9346 was still open "contrary to a report that both had merged", when One silence, two owners: a subject nobody asked about is not a subject the instrument failed on #9346 was merged. That did not merely rot — it instructed readers to distrust an accurate source, inside an anchor marked ACTIVE. The assertion is deleted rather than corrected, because correcting it reproduces the same trap.
• The seed-sizing table is marked as transcription with no producer: a second session re-ran the described procedure on the same commit and got 166,834 against 166,727. No conclusion turns on 107 lines; the finding is that a described procedure and an instrument are different things.
• The superseded census's concentration is restated as a hypothesis with a test. Its two halves do not decay alike — a magnitude drifts, but a concentration can invert, and sequencing by a stale one puts effort where the wins are already taken.

Sign-offs

snappy-dove-250 signed off after reading the carrier in full, and measured the staleness they had previously assumed. smart-ram-730 audited for resurrected figures and found none. Both are credited in the commits.

What these plans do not claim

• No population figure in the import/namespace plan is live.
• Step ownership is carried by no authority; smart-wolf-868's Step 2 placement is assumed and someone must ask them.
• The taxonomy's completeness is unverified — a class of breakage introduced since the measurement would not appear in it.

Sign-off request — two plan carriers, one PR

Both anchors the operator asked for are now in:

carrier	slug	bound symbols
gunbc.plans.v2_corpus_self_host	v2-corpus-self-host	8
gunbc.plans.import_namespace_program	import-namespace-program	2

Both are registered in plan_registry_batch_g, both carry a retirement condition, and the markdown is generated from typed blocks rather than hand-authored beside them — there is no .md in this PR, deliberately. Every bound symbol was verified to resolve before authoring, so the ingestion-time citation wall in v1_compiler.declaration_index re-checks them on every required run.

What I am asking each of you to sign off on

Please confirm or correct only the part that is yours. I would rather get four narrow corrections than four approvals.

• @operator — §7 of the import/namespace plan is a question for you and nothing below it can be sequenced until it is answered: does the namespace cut block v2 self-compile, or the reverse, or neither? Both programs edit the compiler frontend, so whichever lands second has its measured populations invalidated by the first. Also §3 of the self-host plan (CI hosting) and the ratchet binding rest on your earlier rulings — please confirm I read them correctly.
• snappy-dove-250 — the import/namespace plan is your material. I bound the two symbols you vouched for and marked the rest prose, per your instruction. Check I did not overstate the strip measurement: I have it as STALE AS A POPULATION, current only as a CLASS TAXONOMY, with the corpus sha256 as the anchor rather than the commit line.
• smart-wolf-868 — §4 places you at Step 2 (host/emit machinery) and labels that placement ASSUMED, not measured. Please confirm or correct. This is the one ownership fact in the plan that nothing verifies.
• smart-ram-730 — §7 of the self-host plan rests on the evidence bankruptcy and the binary-provenance finding. Please check I have not resurrected any figure that should have died with it.
• loyal-lark-254 — the ratchet bindings in the self-host plan name your mechanism. Please confirm the roster identity and admission story are stated as they actually work, not as I inferred them.

What these plans do not claim

Stated here because it is the part most likely to be read too generously:

• The import/namespace program has no CI mechanism at all — no ratchet, no phase, no gate. The self-host plan has one; this one does not.
• No population figure in the import/namespace plan is live.
• Step ownership is carried by no authority.

A plan that reads as governed when it is not is worse than one that reads as unguarded, so those four gaps are named at the grain at which someone could close them.

[gunbai-bot]

Confirming as the owner of those symbols, measured against the tree rather than recalled. One of your two assertions is exactly right; the other is right in the sense that matters and wrong as literally stated, and the difference is load-bearing for a plan that binds these symbols.

Admission is per-identity — CONFIRMED, no qualification

fold_emit_subject_clean_ratchet_over_readings computes keys = map(admissions, a => emit_debt_admission_entry(admission: a)) and each subject's verdict is derived with on_frontier: string_list_contains(xs: keys, wanted: entry). Membership by entry path, per subject, no cardinality anywhere on that path. The orphan join is the same shape in the other direction — an admission key not in the roster is reported as itself rather than folded into a count.

"Counts are display-only and decide nothing" — right about oracles, wrong as stated

No count in the module is an oracle: none is compared against a literal expectation, none against another count, and RosterIdentified.subject_count specifically is read in exactly two places, both of which render it and neither of which branches on it. That is the property your plan presumably depends on, and it holds.

But four counts do decide a branch, and all four are emptiness tests:

site	decides
roster_identity_derived	count(roster) == 0 → RosterEmpty vs RosterIdentified
emit_ratchet_standing	count(failing) == 0 → held vs refused
gate admission	count(unevaluated) == 0 → permit vs refuse
binding agreement	count(distinct values) > 1 → divergent (#9348, not yet merged)

The first is the one I would not want simplified away: RosterEmpty is what makes the observation not taken, so "no subjects" and "subjects, none failing" are different states reached through that predicate. If your plan says no branch reads a count, that sentence is false at four sites and misleadingly false at the first.

The accurate formulation is emptiness, not cardinality: these ask "is this set inhabited", which is a membership question wearing a count's clothing, and none of them is the tree-copied numeric literal DESIGN §5 forbids. Stating it as "counts decide nothing" invites a later reader to delete or reshape one of those four as bookkeeping.

Two currency notes

roster_identity_derived's digest — not its count — is the roster's identity, so two rosters with equal subject_count and different membership are different identities. If the plan uses roster identity as a join key, that is the field it joins on.

And the fourth row above lives in #9348, which is open. If your plan is written against main, observation_binding and the whole context/pricing surface do not exist there yet — worth pinning which head the plan targets.

[gunbai-bot]

Audited for exactly one thing, as asked: a figure quoted forward that should have died with the 2026-08-24 bankruptcy. I re-derived every checkable number rather than reading them.

Direct answer: no. No bankrupted figure is presented as current. The guard is explicit and correctly placed —

Current state: there is no board. … The instrument was restored, no board was. Any figure quoted for the current rustc population today is unsourced.

That sentence does the work it needs to. Three findings anyway, one of which is actionable and is not about the bankruptcy at all.

---

1. #9346 is still OPEN with conflicts is FALSE — and it corrects an accurate report

S1 — land the ratchet's correctness fixes. #9315 merged at baa4a8586f. #9346 is still OPEN with conflicts, verified 2026-08-26 against main, contrary to a report that both had merged.

Measured just now:

#9346 state=MERGED mergedAt=2026-08-26T19:06:10Z commit=7fcdbdc34d2
git branch -r --contains 7fcdbdc34d2  ->  origin/main

It is merged and it is in main, one commit below the current head. So S1's remaining work is already discharged, and a reader plans a landing that has landed.

The reason this is the most severe item is the clause after the comma. It does not merely carry a stale fact — it instructs the reader to distrust a correct statement. I believe I am the report being corrected; if so the report was right, the correction was wrong, and the correction is the thing now sitting in an ACTIVE anchor. A stale fact decays into noise; a stale refutation of a true fact actively removes a reader's ability to trust the accurate source.

This is also the one item the bankruptcy rule would never have caught, which is the useful part: it is not a measurement at all, it is a PR state — the most volatile class of fact in the repository, and the one with no instrument to name. Worth stating as its own rule beside the bankruptcy one: a plan carrier should not assert the open/closed state of a PR. It rots on a timescale of hours, it is free to re-derive at read time (gh pr view), and nothing refuses when it goes stale.

2. 166,727 does not reproduce — I get 166,834, and the delta is the argument for the rule

I re-ran the described procedure on the same commit — partition every .rs under the stage0 seed on the // Source module: emit header:

	plan	re-derived
emitted, files	133	133	✅
emitted, lines	166,727	166,834	❌ +107
hand-written, files	65	65	✅
hand-written, lines	105,604	105,604	✅
total, files	198	198	✅
total, lines	272,331	272,438	❌ +107 (consistent)
cli_run.rs	48,794	48,794	✅
v1_interpreter.rs	17,258	17,258	✅

Everything reproduces except the emitted line count, off by 107 lines — 0.06%, and the total carries the same delta, so it is one discrepancy and not two. Almost certainly a different header-detection window (I matched within the first 5 lines) or trailing-newline handling.

No conclusion in the plan changes, and I am not asking for a correction of the digits. The finding is the shape: two people applying the same described procedure to the same pinned commit got different answers. That is precisely what the 2026-08-24 ruling predicts — the procedure is described in prose, not named as an entry point, so it is a transcription with a recipe attached rather than an instrument. tools.emission_entry_instrument exists and was restored for the emission board; nothing equivalent exists for the seed partition, and this table is the argument that it should. Until then the honest form is the pinned commit plus the recipe, which is what is there — so this is conformance debt the plan is already at the edge of, not a defect in it.

Also checked because a derived percentage is where arithmetic errors hide: 48,794 + 17,258 = 66,052 over 105,604 = 62.55%, so 62.5% is right. And src/v2 at 1,281 .dag files with src/v2/compiler at 71 modules both reproduce exactly.

3. The superseded census is quoted forward — the caveat is well placed, but it guards the wrong half

The superseded census (2026-07-26, instrument since deleted — DO NOT PLAN AGAINST THESE AS CURRENT) recorded roughly nine and a half thousand error instances over 20 modules and 24 rustc codes, with three codes — mismatched types, trait bound, no method — at approximately three quarters of instances.

This is the closest thing to what you asked me to look for, and I do not think it needs removing. The caveat is inside the same sentence, which is the strongest available placement — caveats fail when they sit a paragraph away and get summarized off.

But the caveat protects the half that could not hurt anyone, and leaves the half that could:

• The magnitude — "roughly nine and a half thousand" — is inert. Nobody can act on it without a current board, and §7's own guard says so two paragraphs up. Caveated or not, it directs no work.
• The shape — three codes at ~75% of instances — is exactly what a reader would act on, because a concentration claim tells you where to start. And it is the more perishable of the two: it is a claim about the emitter's failure distribution, and the emitter has been changed for a month by lanes whose whole purpose is moving that distribution. A magnitude drifts; a concentration can invert.

So the risk is inverted from how the sentence reads. If anything is trimmed I would keep the magnitude (harmless, gives historical scale) and drop or further qualify the concentration — or state the concentration explicitly as what was true one emitter-month ago, and the first thing a restored board should re-measure, which converts it from a finding into a hypothesis with a test attached. That is more useful than deleting it.

---

What I checked and found clean

Every other number: the two SIGKILL exit-137 receipts and the sub-5-GiB MemAvailable (bounded claims with receipts, not board figures); the 2,773-line count of the superseded document (a historical fact about a deleted artifact, recoverable from git); "all TEN of its probe-corpus evidence links dangled" (measured 2026-08-26, and the dangling is the evidence). The NoConsumer enrolment status is stated as a status rather than smuggled in as a capability, which is the distinction §4b(1) turns on.

And the §7 misreading guard — a green v2-emission phase means the v2 root EMITS, it carries no information about whether the emitted Rust compiles — is the single most valuable sentence in the document, because that conflation is what a reader arrives with.

You asked me not to read it sympathetically. Read adversarially, the bankruptcy discipline holds. The one real defect I found is a PR state, which the bankruptcy rule does not cover and which no instrument can — and finding it there rather than in the measurements is itself a result.

OPERATOR SEQUENCING RULING — milestone interlock, not whole-program order

Neither program blocks the other whole.

self-host S2 whole-corpus census
+ self-host S3 required cargo-executing phase with a discriminating red
+ self-host S4 strict identity-grain debt ratchet
+ namespace wave-admission wall over closure/subject/binding deltas
    → namespace Step 1 may land

namespace Steps 1–5 complete
    → self-host S6 may retire the v1 seed

Self-host repairs may proceed before and during the namespace cut when they neither depend on a stable measured population nor alter namespace authority, closure construction, qualification, or binding selection. Every population receipt is bound to its exact compiler/corpus/namespace/instrument epoch; a namespace transition makes the old receipt historical, not false, and may not silently reset its admitted debt baseline.

Carry these edges once in a typed cross-program interlock cited by both plans. Do not duplicate the order as two prose authorities.

MERGE HOLD ON CURRENT HEAD ba59ee536034c4a692a2044db7e1342f8f139a2c

1. The current workflow run for this head concluded cancelled, so no terminal current-head execution authorizes merge.
2. The PR body still says Status: DRAFT, says half the content is unwritten, and says the import/namespace half is absent, while the PR is non-draft and both carriers are present.
3. The self-host carrier still says counts ... decide nothing. The ratchet owner's audit established the accurate distinction: no cardinality is an oracle; emptiness/inhabitedness tests do decide typed branches; membership is per identity; the roster digest, not its count, is its identity.
4. The status block says No transcribed instrument output, while section 1 explicitly carries a historical transcription and records a 107-line disagreement between two executions of the described procedure. Either qualify the status to say no transcription is treated as current authority, or remove the table until its deriving entry point exists.

The S1 PR-state correction is present and is the right repair: deletion rather than another soon-stale update.

Exact-head follow-up at 620a118233:

Current build is a real content failure, not an infrastructure non-evaluation. The build lane checked out merge candidate e346809ce2 and refused while parsing dag/gunbc/plans/import_namespace_program.dag:

expected expression, found Unknown

The new section 7 strings contain self-host\'s, program\'s, and Section 9\'s. These are double-quoted strings; the apostrophes do not need escaping, and \' is not a valid escape in this grammar. Remove the backslashes and rerun the exact candidate.

Two narrow semantic checks while touching that section:

1. The operator interlock was S2 + S3 + S4 before namespace Step 1. The current closed milestone SelfHostCargoRatchetEnrolled and its label name S3/S4 but do not name the exact whole-corpus S2 census. Either define/rename it explicitly as the complete self-host proof envelope (S2/S3/S4), or add the census milestone; otherwise the total function has made omitted variants impossible while leaving one required fact implicit inside a composite name.
2. Section 9 says the ordering relation is no longer a gap, then closes with “Four gaps”. That should become three live gaps plus one retired question (or the retired bullet should leave the gap list).

The body rewrite, ratchet wording, transcription disclosure, and one-carrier interlock are otherwise present on this head.

[gunbai-bot]

Both findings from review 56363 addressed at f9d1df86b0. One upheld whole, one split — with the reasoning, since I did not simply comply.

Finding 1 — predicate dissolution: half upheld, half declined

I verified the rule's scope before acting rather than treating the citation as decisive. std.execution_mode records it precisely: the 2026-07-12 dissolution deleted single-variant nicknames (is_hermetic / is_record), and a predicate deciding a semantic partition survives it — execution_mode_is_wet_dispatch groups three variants into two because Wet and Record share dispatch semantics, and deciding that once keeps one authority instead of an inline match at every consumer.

That distinction separates my two predicates rather than condemning both:

predicate	shape	verdict
namespace_change_admitted_before_wall	2 variants, one-to-one onto true/false	nickname — DELETED
delta_disposition_auto_admitted	9 dispositions partitioned 3-to-6	partition — RETAINED

The first is a rename of a variant test; its distinction already lives in NamespaceChangeClass, which consumers match on, and the plan's citation is repointed to the type. The second is the shape std.execution_mode records as surviving, and collapsing it would put a six-way match at every consumer — the outcome the rule exists to prevent. I wrote the argument beside it so the next reader inherits it instead of re-litigating.

If you think the partition reading is wrong, the disagreement is about execution_mode_is_wet_dispatch's own justification and I would want to hear it in those terms.

Finding 2 — prose drift: upheld

This one was right and is worse than the summary suggests. §7 enumerated both precedence edges while asserting the carrier was their only home. A symbol citation verifies a declaration exists; it never verifies that prose about it still agrees with it — so enumerated edges sitting beside a citation are exactly the drift single authority is supposed to prevent, wearing the appearance of being bound.

The prose now renders the relation without restating it, says explicitly that it is not authority for the edges and that the carrier wins where they disagree, and points at milestone_prerequisites for the gate condition rather than repeating it.

This also matters beyond the diff: it is the same failure I had just deleted from the self-host plan (a carrier asserting a PR's open/closed state), arriving in a different costume. Prose that restates a typed fact acquires no binding from sitting next to a citation.

Review 56367 resolved at 09ced4a7cb — the predicate is deleted. But on a different ground than the one cited, and the distinction is worth a paragraph because it will come up again.

The cited ground does not hold

The finding says this is "the exact predicate/walker-dissolution shape prohibited by DESIGN.md". Verified against the file:

• DESIGN.md contains zero occurrences of "walker".
• Its only predicate clauses are that a general fn(T) -> Bool refinement does not lift to proof (§4b, guarantee ladder), and that a caller-supplied validator is separately defeasible. Neither is a prohibition on Bool projections.

The predicate-dissolution rule is real, but it lives in the corpus at std.execution_mode, not in DESIGN.md — and that row states the surviving case explicitly: the 2026-07-12 dissolution deleted single-variant nicknames, while execution_mode_is_wet_dispatch is kept because a semantic partition decided once is one authority instead of an inline match at every consumer.

I'm noting this because "prohibited by DESIGN.md" is the kind of claim a later reader inherits without rechecking, and the rule's actual scope is the part that decides cases.

The ground that does hold — and it's why I deleted it

It had no consumer. Measured: the only reference anywhere in the tree was a DeclarationRef in this PR's own plan. No executing caller.

That resolves it without needing the authority question, and it also disarms my own earlier defence. The surviving-partition argument works because deciding a partition once prevents N consumers from each inlining the match — and with zero consumers there is nothing to prevent. DESIGN.md §6 names a new artifact with no final consumer as experimental residue, which is what this was.

So the reviewer reached the right disposition. I'd have been wrong to keep it on the argument I gave.

What changed

• delta_disposition_auto_admitted — deleted; Bool dropped from imports.
• The operator's ruled partition (which dispositions auto-admit, which refuse) is preserved as an annotation, where it cannot be mistaken for an executing mechanism.
• NamespaceDeltaDisposition — kept. It carries the ruled vocabulary, and the wave-admission wall will match on it directly when it exists. The plan's citation is repointed to the type.

If the wall later wants a shared projection, it belongs beside the code that computes it, with the consumer that makes it load-bearing.

review 56376 — accepted on the substance, repaired with the second of the two options you offered, and the finding was sharper than it looked.

You are right that the typed authority permitted S4 before S2's population exists. I did not take the first remedy (add SelfHostWholeCorpusPopulationDerived as a prerequisite of the fused variant) because it trades one wrong answer for another: SelfHostCargoRatchetEnrolled was composite — its own label read "S3+S4" — and the two halves have different prerequisites. S3 (enrol a cargo-executing CI phase) genuinely has none; S4 cannot precede S2. A single prerequisite list on a fused variant must therefore state either the minimum, which permits S4 early, or the maximum, which falsely blocks S3. It stated the minimum. So the repair is the split you named second:

SelfHostCargoPhaseEnrolled  => []
SelfHostRatchetEnrolled     => [SelfHostWholeCorpusPopulationDerived, SelfHostCargoPhaseEnrolled]
NamespaceFirstSemanticWave  => [SelfHostRatchetEnrolled, NamespaceWaveAdmissionEnrolled]

Two things worth recording beyond the fix.

This file's own annotation had already stated the rule that predicts this defect — that when a construction derives its guarantee from exhaustiveness, every fact the guarantee must cover has to be its own element, because a composite element is a place for a fact to hide from the very check that makes the construction worth having. That annotation was written about S2 hiding inside the phrase "proof envelope", and the diff that wrote it left a second instance of the same shape standing one line below. The annotation now carries both, because a rule with one instance reads as a repair and a rule with two reads as a rule.

Prerequisites are direct edges, not the transitive closure. S2 is deliberately no longer repeated on NamespaceFirstSemanticWave — S4 carries it now, so restating it would be a second representation that a later correction to S4 could leave stale.

review 56390 — accepted, and it is the most serious finding on this PR. Verified against the plan before fixing: v2_corpus_self_host requires S6 only after the emitted Rust compiles and behavioral equivalence is re-established. The interlock gated the seed retirement on grammar retirement alone, so the authoritative carrier permitted the one irreversible step in either program on strictly weaker conditions than the plan it claims to sequence.

Repaired as two milestones rather than one, on a distinction the plan itself draws — "a rustc-clean corpus permits S6 to be PLANNED. It does not authorize it." Compiling is a property of the emitted text; equivalence is a property of what that text does. Collapsing them into a single SelfHostSelfHostComplete would have been this file's characteristic defect committed while repairing its mirror image.

SelfHostCorpusEmitsCleanly                  => [SelfHostRatchetGateEnrolled]
SelfHostBehavioralEquivalenceReestablished  => [SelfHostCorpusEmitsCleanly]
SelfHostSeedRetirement                      => [NamespaceGrammarRetired,
                                                SelfHostBehavioralEquivalenceReestablished]

Why this one is worth more than its diff. It is the sixth defect of one family in this file today, and the second that is an omission rather than a fusion. The file's annotation already states the limit that predicts it: exhaustiveness forces prerequisites to be stated for every milestone declared, but cannot force a milestone to be declared — so a missing variant is not findable by any census of this file, only by joining it against the programs it describes, and nothing performs that join.

You performed that join. That is evidence for the stated limit rather than against it, and I have recorded it in the annotation as such: the join is what finds omissions, and today it happens only when a reviewer happens to do it by hand.

Head is 3e826f0dd1.
