workflow-fix: watcher post-hoc external-marker triage observer

Overview / Motivation

Auto-filed by /daily 2026-07-03 from a recursion-guard-parked workflow-fix candidate.

Goal

add a non-gating watcher pass re-running triage_candidates_since_last_dispatch at recent compute breadcrumbs and flagging a missing/none triage line against a non-empty candidate set

Workflow gap

• Bug observed: no post-hoc check that a dispatch actually triaged external advisory markers; an 'external-markers triaged: none' line against a non-empty candidate set goes unnoticed
• Why it is a workflow gap: see candidate note
• Confidence (emitter): medium

Proposed change (candidate sketch — refine in planning)

add a non-gating watcher pass re-running triage_candidates_since_last_dispatch at recent compute breadcrumbs and flagging a missing/none triage line against a non-empty candidate set

Scope / surfaces

• Primary target: scripts/autonomous_session_watch.py, scripts/tick_triage.py
• Grep the workflow surface for the pattern before editing; list every hit in the plan.

Constraints / invariants

• Workflow-surface only; scripts/workflow_lint.py --check-asks passes; ruff on touched files passes.

Provenance

• workflow_fix_target: scripts/autonomous_session_watch.py, scripts/tick_triage.py
• fingerprint: 3a064def88df

routed: parked — running under workflow_fix_target Provenance (recursion guard, .claude/rules/workflow-fix-on-bug.md § Recursion guard). Two concrete follow-ups surfaced by the plan (sec12) + Phase-2 critics, logged for the parent orchestrator / next PM pass, NOT auto-filed from this session:

1. target_file: .claude/agents/research-pm.md — emitter-side --by convention for cross-session advisory posts (PM-chat/watcher advisory markers SHOULD set a distinctive --by, e.g. pm-chat / watcher), sharpening triage_candidates_since_last_dispatch's mechanical layer. confidence: medium.
2. target_file: scripts/autonomous_session_watch.py (or scripts/tick_triage.py) — post-hoc compliance observer: a non-gating pass re-running triage_candidates_since_last_dispatch at recent compute breadcrumbs and flagging an 'external-markers triaged: none'/missing line against a non-empty candidate set (Statistics-lens S6 + Alternatives-lens concern 1; mechanizable). confidence: medium.
