Pure helpers landing ahead of runPlanSkillCounting:
- parseQuestionPrompt(visible) — extract the 1-3 line prompt above
the latest "❯ 1." cursor, normalize to a 240-char snippet
- auqFingerprint(prompt, opts) — Bun.hash of normalized prompt + sorted
options signature; distinct prompts with shared option labels
(the generic A/B/C TODO menu) get distinct fingerprints
- COMPLETION_SUMMARY_RE — terminal-signal regex matching all four
plan-review skills' completion / verdict markers
- assertReviewReportAtBottom(content) — checks "## GSTACK REVIEW
REPORT" is present and is the last "## " heading in a plan file
- Step0BoundaryPredicate type + four per-skill predicates
(ceo / eng / design / devex) — fire on the answered AUQ's
fingerprint, marking the end of Step 0 deterministically
(event-based, not content-based, per Codex F7)
Plus 37 deterministic unit tests covering option-label collision
regression, prompt extraction edge cases, predicate positive AND
negative cases, and review-report-at-bottom triple-check
(missing / mid-file / multiple trailing).

Pure classifier extracted from runPlanSkillObservation's polling loop so
unit tests can exercise the actual branch order with synthetic input
strings. Runner gains:
- env? passthrough on runPlanSkillObservation (forwarded to launchClaudePty).
gstack-config does not yet honor env overrides; plumbing is in place for a
future change to make tests hermetic.
- TAIL_SCAN_BYTES = 1500 exported constant. Replaces a duplicated magic
number in test/skill-e2e-plan-ceo-mode-routing.test.ts so tuning stays
in sync.
- isPermissionDialogVisible: the bare phrase "Do you want to proceed?" now
requires a file-edit context co-trigger. Other clauses unchanged. Skill
questions that contain the bare phrase are no longer mis-classified.
- classifyVisible(visible): pure function. Branch order silent_write →
plan_ready → asked → null. Permission dialogs filtered out of the
'asked' classification so a permission prompt cannot pose as a Step 0
skill question.
Adds 24 unit tests covering all classifier branches, edge cases, and the
co-trigger contract.
