fix(agents): enforce registered autonomy declarations (#454)

[bioedca]

Summary

• Require an autonomy declaration to exactly match a registered admitting enum after normalization.
• Treat a heading's first non-blank line as the declaration while scanning only its remainder for explicit refusal tokens.
• Refuse qualified bullet keys such as Autonomy after unblock, including when a neighbouring status line says unblocked.
• Scan an autonomy table row for refusal tokens without making table rows a new admission path.
• Preserve canonical refusal-token messages and distinguish absent, restricted, and unregistered values.

This is the smallest complete increment for #454. It changes only the autonomy machinery in .agents/bin/claim.py and its behavioral tests; no contract file, dependency, schema, scientific claim, or citation changes.

Linked tracking

• Closes: fix(agents): claim.py admits conditional, table-row and after-unblock autonomy #454
• Milestone: none assigned
• FR: n/a — repository agent tooling
• Risk (may only increase): high
• Risk rationale: this is the mutex admission gate; the implementation fails closed and the live-corpus/doctor checks guard against refusing currently claimable work.
• Final head SHA: 6480b7d08f04c4198814cbb713e2cc5cadad434f
• Codex — first: clean — the posted provider artifact fix(agents): enforce registered autonomy declarations (#454) #462 (comment) says Codex Review: Didn't find any major issues. and records 6480b7d08f, mechanically expanded to 6480b7d08f04c4198814cbb713e2cc5cadad434f
• Codex closing review: n/a — CodeRabbit cap not spent
• Greptile: not requested — dispatcher precheck found 28/50 seat credits used, but Tether is already at 18/16 of its monthly share; no credit spent
• CodeRabbit — the last metered gate: completed COMMENTED review fix(agents): enforce registered autonomy declarations (#454) #462 (review) on 6480b7d08f04c4198814cbb713e2cc5cadad434f; it reported one 🔵 Trivial / 💤 Low value diagnostic-wording nitpick on .agents/bin/claim.py, disposed under the agent-layer floor at fix(agents): enforce registered autonomy declarations (#454) #462 (comment), with no actionable finding outstanding
• Provider that did not review: none yet
• Findings: 0 serious | 1 below the floor | 0 withdrawn
• Human sign-off: n/a — no new scientific claim or citation
• Science gate: required after the review lane because the actual diff contains executable agent-layer code; this worker will not arm auto-merge

Acceptance evidence

Red against the claim base (4e61ad11aa44e1348188eeb2f36879d9b2b4f738):

• Conditional refactor(gui): settle on one Qt import convention across tether.gui #339/docs(prd): rewrite §9 as acceptance philosophy and harvest PLAN.md's durable content #379 bodies and both after-unblock bodies: 4 failed because each created a claim ref.
• New table/token/message guards together: 10 failed before implementation.
• R1-only intermediate: the original seven refusal cases plus the three conditional cases were 10 passed; the unchanged explanatory-prose guard was red (1 failed), demonstrating why the heading remainder must be scan-only; the after-unblock refusal was also red (1 failed), demonstrating the qualified-key gap.
• Mutation demonstration: after collection fixed the parameter set, temporarily emptying AUTONOMY_REFUSES still ran the table-row assertion and produced 1 failed; the mutation was reverted.

Green on the final implementation:

• pytest tests/test_claim.py: 123 passed, 1 skipped.
• The over-refusal input bodies and assertions remain unchanged and pass: test_ordinary_prose_under_the_declaration_does_not_refuse_a_ready_issue and all eight cases in test_a_restrictive_declaration_governs_wherever_it_sits_in_the_source.
• The seven pre-existing refusing cases pass unchanged, including canonical maintainer decision and human action substrings for separator variants.
• git grep -n "is not a registered autonomy value" .agents/bin/claim.py tests/test_claim.py locates the new third refusal category; its test asserts that substring is absent from the missing and refusal-token messages.
• git diff --name-only origin/main...HEAD prints exactly .agents/bin/claim.py and tests/test_claim.py; AGENTS.md was checked and not edited.

Live-corpus remeasurement

Retrieved from the GitHub API on 2026-08-28 and evaluated in memory against the claim base and final branch parser:

Measure	Count
Open issues	95
Admit before	82
Admit after	27
Admit → refuse	55
Refuse → admit	0
Open status:ready issues	14
Ready admitting before	14
Ready admitting after	14
Ready admit → refuse	0

The 55 flipped numbers are #162, #167–#169, #171, #175, #177, #179, #181–#183, #185–#186, #249, and #339–#379, matching the accepted blast radius. One open issue was added since grooming; it changes the open/admit totals but not the 55 flips.

One-off measurement script (not committed):

import importlib.util, json, subprocess, types
from pathlib import Path

base_sha = "4e61ad11aa44e1348188eeb2f36879d9b2b4f738"
issues = json.loads(subprocess.run(
    ["gh", "issue", "list", "--repo", "bioedca/tether", "--state", "open",
     "--limit", "400", "--json", "number,body,labels"],
    check=True, capture_output=True, text=True,
).stdout)
spec = importlib.util.spec_from_file_location("after", Path(".agents/bin/claim.py"))
after = importlib.util.module_from_spec(spec)
spec.loader.exec_module(after)
source = subprocess.run(
    ["git", "show", f"{base_sha}:.agents/bin/claim.py"],
    check=True, capture_output=True, text=True,
).stdout
before = types.ModuleType("before")
exec(compile(source, f"{base_sha}:claim.py", "exec"), before.__dict__)
admits = lambda module, issue: module._autonomy_refusal(issue.get("body") or "") is None
before_set = {i["number"] for i in issues if admits(before, i)}
after_set = {i["number"] for i in issues if admits(after, i)}
ready = {i["number"] for i in issues if any(x["name"] == "status:ready" for x in i["labels"])}
print(len(issues), len(before_set), len(after_set), len(before_set - after_set),
      len(after_set - before_set), len(ready), len(ready & before_set),
      len(ready & after_set), sorted(ready & (before_set - after_set)))

claim.py doctor was also run from the final branch and from the claim-base source. Both reported the same 14 ready issue numbers, and every entry had autonomy: true. This is a no-regression check, not evidence by itself that the fix landed.

Self-review checklist

• Schema freeze respected — no schema change.
• conda-lock updated if dependencies changed — no dependency change; no lock update required.
• Tests added/updated — behavioral claim/ref tests cover each accepted rule.
• Docs updated — not applicable; no user-facing product interface and no contract edit. The parser's load-bearing docstrings were updated beside the reversed decision.
• Data policy respected — no data or fixtures added.
• No secrets committed — pre-commit secret/REUSE/large-file gates passed.
• Code scanning clean — all draft CI and CodeQL checks are terminal success.
• Review complete — Codex clean and CodeRabbit last-metered review complete on the exact final head; no actionable finding remains.
• Provenance stamped — not applicable; no analysis output.
• New tunables registered — none added.
• Scientific/statistical claims carry a citation — none introduced; no citation required.
• A resolved PRD decision that changed is reflected in PRD/ADR — not applicable; the registered choices and admission boundary are unchanged, and the accepted issue explicitly requires no contract/ADR edit.

Testing

• micromamba run -n tether pre-commit run --all-files — passed all hooks.
• QT_QPA_PLATFORM=offscreen micromamba run -n tether pytest -m "not large and not sidecar and not deep" — 2971 passed, 18 skipped, 34 deselected on macOS, Python 3.12.13, PySide6 6.11.1.
• Docs gate: not run; no docs change.
• Schema gate: not run; no schema change.
• Optional author-side local Codex review: could not start because the native package is missing its bundled executable (ENOENT). This posts no artifact, satisfies no provider leg, and does not replace the required review.

Current handoff state

• Step: repository review lane complete on exact head 6480b7d08f04c4198814cbb713e2cc5cadad434f; science-material handoff is gate-pending.
• Asked: CodeRabbit completed the full review at fix(agents): enforce registered autonomy declarations (#454) #462 (review); its sole sub-floor finding was disposed at fix(agents): enforce registered autonomy declarations (#454) #462 (comment).
• Outstanding: a SCIENCE-GATE: approve verdict on this exact final head; all required CI is green, no actionable review finding remains, and CodeRabbit created no inline review thread.
• Next expected event: the dispatcher obtains science-gate approval on 6480b7d08f04c4198814cbb713e2cc5cadad434f; this worker does not arm auto-merge for a science-material diff.

Summary by CodeRabbit

• Bug Fixes
  • Improved recognition of autonomy declarations across supported formats, including tables, headings, and qualified statements.
  • Prevented explanatory text or later prose from incorrectly granting claim eligibility.
  • Standardized detection of refusal terms regardless of separator formatting.
  • Added clearer distinctions between missing, restricted, and unregistered autonomy declarations.
  • Ensured only exact, standalone registered autonomy values can authorize claims.

📝 Walkthrough

Walkthrough

The claim parser now uses structured autonomy declarations. It scans all declaration sources for refusal tokens and admits claims only for exact bare registered values. Tests cover qualified, table, post-unblock, separator, diagnostic, and ordinary-prose cases.

Changes

Autonomy admission

Layer / File(s)	Summary
Structured declaration extraction .agents/bin/claim.py	Autonomy values now retain qualifiers, source locations, and scan-only status. Qualified bullets, heading continuation lines, and autonomy table rows receive restrictive or scan-only handling.
Restriction scanning and exact admission .agents/bin/claim.py	Refusal tokens are checked across all extracted values before admission. Only exact bare registered autonomy values can authorize claims.
Eligibility regression coverage tests/test_claim.py	Tests cover qualified and post-unblock declarations, separator normalization, table restrictions, refusal precedence, distinct diagnostics, and scan-only prose.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 6480b

The change tightens autonomy admission and refusal detection, with the supplied test and corpus checks passing. No actionable merge-blocking risk remains; a minor diagnostic wording follow-up does not affect behavior.

.agents/bin/claim.py (1)

639-653: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Diagnostic wording claims a declaration for scan-only prose.

Scan-only records reach this message. A heading remainder then reports declares autonomy 'The upload step is a maintainer decision.' (body heading remainder), and a table row reports the raw cell text including the trailing |. The groomer reads that the issue declares an autonomy value that it never declared.

Separate the two wordings so the message names the restriction rather than a declaration.

♻️ Optional: name a restriction for scan-only sources

     for value in values:
         raw = value.raw.strip()
         flat = _flatten_autonomy(value.raw)
         refused = [token for token in AUTONOMY_REFUSES if _flatten_autonomy(token) in flat]
         if refused:

+                f"carries the restriction {raw!r}"
+                if value.scan_only

SCIENCE-GATE: approve

Head reviewed: 6480b7d

Scientific assessment: the public diff changes only an issue-autonomy admission parser and its behavioral tests. It introduces or modifies no biological, physical, clinical, statistical, or data-processing claim; no scientific algorithm, oracle, tolerance, reference value, dataset, provenance record, or scientific citation is changed.

DOI/PMID-backed reasoning: no substantive scientific proposition is introduced by this diff, so no primary-literature citation or retraction check is applicable. This approval is limited to scientific soundness and does not assess repository mechanics or merge readiness.

[bioedca]

Merge-block diagnosis (2026-09-05). Every required check is green, there are zero review threads, mergeable is true and auto-merge is armed, yet mergeStateStatus reads BLOCKED. The cause is the head commit's signature: 6480b7d08f04c4198814cbb713e2cc5cadad434f reports verification.verified=false, reason=unsigned, and the main-baseline ruleset carries required_signatures. GitHub names no rule for this state; the same silent block was diagnosed on #200.

The fix is a re-signed commit carrying the identical tree, force-pushed over the branch. AGENTS.md forbids an agent from force-pushing and this session's classifier also refused the local rewrite, so it is a maintainer step (native Git Bash; in WSL the repo config already resolves the key, so drop the -c override):

git fetch origin
git worktree add --detach /c/Users/bioed/AppData/Local/Temp/rs454 origin/agent/issue-454
cd /c/Users/bioed/AppData/Local/Temp/rs454
git -c user.signingkey=C:/Users/bioed/.ssh/id_ed25519_signing.pub commit --amend --no-edit
git log -1 --format='%H %G? %s'                                     # must print G
git diff --quiet 6480b7d08f04c4198814cbb713e2cc5cadad434f HEAD && echo tree-identical
git push --force-with-lease=agent/issue-454:6480b7d08f04c4198814cbb713e2cc5cadad434f origin HEAD:agent/issue-454

If origin/main has moved by then, add a signed git merge --no-ff origin/main before the push (clean merge = non-material). Because the tree is unchanged, the Codex and CodeRabbit evidence recorded above survives under the non-material rule; the moved head then takes the ordinary Codex close on the new SHA before --match-head-commit is armed. Note the auto-merge already armed here will fire on the re-signed head as soon as CI is green; disable it first (gh pr merge 462 --disable-auto) if the closing read should land before the merge.
