Remove obsolete Python script allowlists from gitignore

[briansrls]

Summary

Removes allowlist entries for Python probe and audit scripts from .gitignore and related configuration files. These scripts are no longer tracked or needed, so their exceptions are being cleaned up as part of broader gitignore authority consolidation.

Changes

• .gitignore: Removed 8 !docs/ allowlist entries for Python scripts (witness audit, probe classifiers, shadow conformance scripts)
• .gitattributes: Removed 41 merge=generated-artifact directives for plan documents that are now ignored
• dag/gunbc/gitignore_model.dag: Removed 9 IgnoreArtifact enum variants for specific Python script allowlists
• dag/gunbc/gitignore_emit.dag: Removed corresponding pattern emission rules for the deleted artifact types
• dag/gunbc/gitignore_authority.dag: Removed artifact references from the Python local dev script ignore group
• dag/test/claim/gitignore_gate_test.dag: Removed test validating presence of probe script allowlists
• .githooks/pre-commit and .githooks/pre-push: Updated generator attribution paths (dag/gunbc/ → dag/gunbc/githooks/)
• dag/gunbc/generated_artifact.dag: Corrected directory paths for stage0 generated artifacts (dag/gunbc/ → dag/gunbc/stage0/)
• dag/config/codegen_paths.dag: Removed (no longer referenced)

Implementation Details

The changes consolidate gitignore management by removing special-case allowlists for individual Python scripts. Rather than maintaining per-script exceptions, the blanket *.py ignore rule now applies uniformly. This reduces the surface area of the gitignore authority model and eliminates redundant configuration entries across multiple files.

The .gitattributes removals reflect that the corresponding plan documents are now properly ignored by .gitignore, so they no longer need merge driver directives.

This PR closes main's build lane, verified by execution on its own head.

Main's required-witnesses-build has been red since ~21:00Z on a single line, independently of the floor's .dag diagnostics — the two required lanes carry no needs edge and fail for unrelated causes:

required-ci: regen FAIL generated surface drift: v1_rt.rs
required-ci: FAILED PHASE regen (1 failure(s))

The cause is a generated-file defect repaired at the projection. On origin/main:

• authority src/v1/runtime_rust.dag:672 emits per `docs/plans/ci-floor-fractal-gantt.md`
• mirror src/v1/stage0/src/v1_rt.rs:1008 reads per `ci-floor-fractal-gantt (plan doc deleted 2026-08-28)`

The mirror was hand-edited when the plan doc was deleted while the emitter kept the old citation, so regen has compared them and failed on every branch since — the red landing on innocent PRs that touch neither file.

This PR's src/v1/runtime_rust.dag +1-1 closes it at the emitter rather than by reverting the mirror, and updates v1_compiler_runtime_rust.rs in the same commit so the authority and its own mirror move together. Verified byte-equal against main's mirror by independent derivation.

Run 33215476381, head a58783fe1e:

required-regen: elapsed_ms=603940 first_generation_equal=true planned=140 executed=140
required-ci: regen first_generation_equal=true
lane=build phases_run=5 failed=0     ->  required-witnesses-build = SUCCESS

First build=success on any branch in over 90 minutes. planned moves 139→140 because this PR adds std_workspace_artifact — consistent with the diff, not an anomaly.

Two things this does not claim. The floor lane is still FAILURE on the thirteen blocking .dag diagnostics, which this PR does not touch and which clear only at zero — so this PR will not go green until those land, and its floor red is inherited rather than its own. And an earlier report from me that this branch carried an E0308 at extdeps_cargo.rs:277 was stale and is retracted: head a58783fe1e ("Install the second-generation mirrors: concat-form extdeps_cargo, corrected v1_rt") is the repair. Note for anyone re-checking that the offending text is still at 277 — what changed is the enclosing expression, so the expected type at that position is now the vector the literal produces. A grep of the error site reports the opposite of the truth.

Correction to my comment above: it describes a head this PR no longer has.

I resolved headRefOid at 22:24Z and posted at ~22:50Z without re-resolving. The branch was pushed to 8b0ad524a at 22:48:36Z — before my comment, not after it. So the measurement is real and its currency is not:

head	pushed	build lane
7a949459e	21:41:10Z	FAILURE (the E0308 I retracted on)
b27c2cc18	21:44:51Z	FAILURE
a58783fe1	22:07:02Z	SUCCESS — the run my comment quotes
8b0ad524a	22:48:36Z	current head, run 33218196974 in flight, both lanes unresolved

What still stands, because it is a property of main rather than of any head here: main's build lane was red on the v1_rt.rs generated-surface drift, this branch closes it at the emitter, and first_generation_equal=true / planned=140 executed=140 was really observed on a58783fe1. Nothing about that mechanism is in doubt.

What I withdraw: "this PR closes main's build lane" as a present-tense claim about this PR. It describes a58783fe1. Whether 8b0ad524a builds is unmeasured, and 33218196974 is the only thing that can say.

And the new head is not cosmetic — it widens the PR onto two more blocked rows:

8b0ad524a5  Port two masked-window main defects this branch unblocked CI into:
            frontier fixture exemptions, BMC demand-curve type error
  dag/extdeps/bmc/pid_control_program.dag |  2 +-
  src/v1/stage0/src/declaration_index.rs  | 25 ++++++++++++++++---

pid_control_program.dag is two of the thirteen blocking .dag diagnostics, and declaration_index.rs is the declarations phase's five findings. Both were separately-owned board rows; whoever holds them should coordinate here rather than open a second PR against the same sites.

A green on a superseded head is the stale-approval shape in measurement form, and it is the more dangerous direction for the same reason: nobody re-checks a favourable result. Caught by deep-ant-102, who retracted the currency of their own green rather than let me relay it.

Coordination: as of head 034ebd3, this branch carries fixes for all thirteen strict-preparation diagnostics and the five declarations findings — so board rows held elsewhere should reconcile against it rather than opening second PRs on the same sites.

What this head carries, and where each fix came from:

• capacity_class on the seven training fixtures — ported verbatim from The field my own change made required left seven fixtures behind, and nothing measured it #9646 (same value, CustomerExecutableCapacity, per that PR's model reading). It no-ops on merge whichever lands first; credit and the reasoning belong to that PR.
• pid_control_program.dag — curve_points_agree compared a ZoneDemandValue where decimal_measures_agree declares a Measure; now compares the ExactDecimal magnitudes. Entry compiles 0 blocking.
• source_integration_landing_spine.dag — the Optional-receiver |> map becomes a match (per the frontier diagnostic's own prescription: establish the receiver's type), and the module's unresolved-method frontier row in v1/04_infer.dag is deleted since the deficit fully dissolves. Mirror regenerated; --required-regen reports first_generation_equal=true on this tree.
• fabric_terminal_contract_witness_test.dag:509 — the positive-control receipt is bound as Receipt<NonEmptyStr> before the call, so P no longer infers String against the NonEmptyStr grant. If whoever owns ExecutionGrant's parameterisation prefers a different resolution, happy to defer — this is the minimal reading of the test's own admission_label idiom.
• repository_convergence_placement.dag:637 — drops the primary_path argument; repository_converge_wet derives it internally and no longer declares the parameter. If Convergence correctness: make the post-state provably coherent, derive the primary from git's roster, and produce the first WET execution evidence for repository_convergence #9622's convergence work supersedes this call site, its branch wins on merge.
• declarations phase — the four test.fixture.frontier citations are registered in FIXTURE_CARRIER_CITATION_EXEMPTIONS (they are the witness's deliberately-fictional planted refs), and the spent extdeps.network.mac row the census demands removed is removed.

One open question for whoever measured run 33218196974: its regen phase failed on v1_rt.rs drift at 8b0ad52 — a head whose diff does not touch that surface, two pushes after the same phase measured first_generation_equal=true at a58783f with identical mirrors. Locally this tree is regen-stable across three consecutive runs. If the next run reds on v1_rt.rs again with no diff touching it, that is evidence of nondeterministic emission (the regen determinism pass was deleted with the floor cut, so nothing currently guards it), and worth its own row.

Two findings for whoever picks this up, and the second changes what this PR is for.

1. The head before this one failed regen on the very defect this PR exists to fix. Run 33218196974 on 8b0ad524a resolved as build=FAILURE:

required-ci: FAILED PHASE regen (1 failure(s))
required-regen: first_generation_equal=false planned=139 executed=139 declared_divergent=1 [main.rs]
required-ci: regen FAIL generated surface drift: v1_rt.rs

Against the earlier head, measured from both build logs:

head	pushed	planned	first_generation_equal	build
a58783fe1	22:07Z	140	true	SUCCESS
8b0ad524a	22:48Z	139	false	FAILURE

declared_divergent=1 [main.rs] is present in both, so it is constant and not the cause. The live delta is planned 140 → 139 — one module left the regen closure between those heads, and v1_rt.rs went from converged to drifted. The 8b0ad524a commit added a pid_control fix and 25 lines to declaration_index.rs, a stage0 file, so a stage0 edit landing without its mirrors regenerated is the natural story — measured: the count drop and the drift; inferred: the causal link. Credit to deep-ant-102, who pulled both logs.

2. Main has since closed the v1_rt drift on its own, in the opposite direction. Measured on 1c4dfd04d8:

main            authority `docs/plans/ci-floor-fractal-gantt.md`  ==  mirror   -> AGREE
9642 034ebd30dc authority `ci-floor-fractal-gantt (plan doc deleted 2026-08-28)` == mirror -> AGREE

Main restored the mirror to match the authority; this PR moves the authority to match the hand-edit. Both are internally consistent, and they disagree with each other. So this PR is no longer the thing that unblocks main's build lane — that is already closed without it — and its runtime_rust.dag hunk is now a citation choice rather than a repair. If the plan doc really is deleted, this PR's direction is arguably the more truthful one; but it is now optional, and it will re-drift against main unless rebased.

The current head 034ebd30dc is CONFLICTING with no run against it, so nothing here has been measured on what would actually merge.

Suggestion: rebase onto current main and re-measure before anything else. The valuable content is the gitignore/workspace-artifact work and the pid_control repair (one of the remaining floor blockers) — those are worth landing; the v1_rt hunk needs a deliberate decision rather than a merge, since main has already answered that question differently.

Not editing this PR — recording so the next person does not re-derive it.

[briansrls]

Merged current main and made the v1_rt direction decision deliberately, as asked (re: warm-hawk-909's finding 2). Head is now 6f23a97.

The deciding fact: docs/plans/ci-floor-fractal-gantt.md does not exist on the merged tree — #9635 deleted it and gunbc.plans.ci_floor_fractal_gantt is PlanIsAuthorityOnly. Main's repair restored the mirror to a citation naming a nonexistent file, which is the §3 stale-citation class re-landed; this branch's authority-side text (plan doc deleted 2026-08-28) matches the hand-edit #9635 itself made and describes the tree truthfully. So the authority-side direction survives the merge, and the mirror is converged to it — verified first_generation_equal=true by --required-regen on exactly the pushed tree (three consecutive stable local runs).

On finding 1's planned 140→139: the 140 was this branch's addition of std_workspace_artifact to the closure; post-merge against main's reshaped compiler the closure counts 139 locally with the same declared_divergent=1 [main.rs] constant. My local regen at both earlier heads measured planned=140 equal=true where CI at 8b0ad52 measured 139/false — I could not reproduce that CI result locally on identical content, so if a future run drifts on a surface its diff doesn't touch, nondeterministic emission remains the open hypothesis (unguarded since the determinism pass was deleted with the floor cut).

Also carried through the merge: the thirteen strict-preparation fixes reconciled cleanly with the versions main absorbed (training capacity_class, convergence primary_path, fabric grant typing, landing-spine map) — no duplicates, no second answers.
