Extract helpers / flatten conditionals in 11 blocks that rated C(11)+
under xenon --max-absolute B, dropping pr_gate.py module rank B->A in
the process. Pure move-and-call refactors: each extracted helper holds
the original logic verbatim and the caller delegates to it; no control
flow, return values, or side effects changed.
Sites: validators._extract_strs, sequencing.dev_task_collision_edges,
evidence_builder.build_task_handoff, intake_driver._coerce_draft,
task.claim_task_for_agent (2 guards), prompter.create_task_from_draft
(validate+assignee), pr_gate._gate_decision (3 helpers),
orchestrator._handle_stopped_container + _reap_with_service,
_impl._create_subtask_from_inputs + complete.
_impl helper returns tuple[TaskNature, list[str]] to preserve mypy
narrowing of acceptance_criteria at the TaskCreateRequest site.
Also fix vulture: rename unused __aexit__ param tb->_tb in
test_conventions_cache_put.py (was hidden while xenon short-circuited
the gate).
Post-audit sweep over the 135 audit-fix commits since 19a474d3:
1. Stripped every # Fxxx: audit-ID token from comments AND every Fxxx token
from docstring openings across 211 blocks / ~626 lines. The CEO flagged
these twice: audit-issue IDs in code confuse future devs/agents. The
descriptive text is preserved; only the Fxxx token is removed (and bloated
narrative blocks trimmed to 1-3 lines keeping the one non-obvious invariant).
2. Trimmed bloated comments/docstrings to the concise standard (1-3 lines).
3. Added missing behavior-change docs for the audit-fix batch: prompts/roles
(documenter, pr_reviewer, qa), user-facing docs (api auth, websockets,
agent-gateway, megatask, merge-model, task-lifecycle, grok, resilience,
conventions, panel, security, troubleshooting), and the RAG corpus (cell-pm,
main-pm, pr-reviewer, qa roles; conventions; messaging-tools; escalation;
megatask; task-claiming workflows).
Comment/docstring/prose ONLY — zero code-line edits (verified: the diff
contains no def/class/return/if/for/await/assignment/call lines). Gates green:
ruff format + ruff check clean, mypy clean on roboco/. The only pytest failures
are the pre-existing sync_branch tracing-decision gap (B1, 250be5c2) — not
sweep-caused and tracked separately.
Converts 115 `# type: ignore[...]` suppressions across 23 test files to
no-suppression patterns (helper-return widening to Any, local Any aliases,
cc:Any aliases, cast at narrow call sites, typed fixtures) so the hard
no-type:ignore convention holds across tests/. No test logic or assertions
changed — only mock-wiring mechanics and type annotations.
Gate: ruff check tests/ clean; mypy tests/ (538 files) clean; 176 changed-file
tests pass. Zero real suppressions remain (the 7 grep hits are 3 hygiene-
checker string-literal test inputs and 4 prose mentions in comments).
Two task creates for the same project/HEAD can race to populate the
conventions cache; the loser's INSERT fails the partial-unique index with
IntegrityError. A bare session.add + flush poisons the shared session (the
task-create transaction rides the same session), so every subsequent op
raises 'this session is in error state' and task creation crashes.
Run the INSERT in a savepoint (begin_nested) and swallow the IntegrityError:
only the savepoint rolls back, the outer transaction stays usable, and the
winner's row satisfies the next _cache_get.
