Sub-track 1 of the 5-sub-track result_migration_20260616 campaign.
Audit-driven research task: classify 43 ambiguous exception-handling sites
(24 UNCLEAR + 19 INTERNAL_RETHROW across 11 files) and update the
audit script's heuristics. No production code change.
Scope: 11 files, 43 sites, T-shirt S. The per-site decisions feed
sub-tracks 2-4 (small_files, app_controller, gui_2) as their starting
migration scope.
Files: spec.md, plan.md, metadata.json, state.toml under
conductor/tracks/result_migration_review_pass_20260617/. Row added
to conductor/tracks.md.
Phase 6 tasks (t6_1, t6_2, t6_3) and the phase itself marked completed.
All 16 task entries now have status=completed.
All 6 phase entries now have status=completed.
This is the final state.toml commit for the track.
Track marked shipped 2026-06-17. All 6 verification criteria evaluated
with PASS/EXCEEDED/READY status and notes. 7 pre-existing test failures
documented with root cause and pre_existing_failures_remaining flag.
Risk register updated: scope_creep=none, behavior_change=none,
doc_drift=medium (error_handling.md deprecation section required
surgical rewrite to historical note).
No deferred_to_followup_tracks (this track completed cleanly).
7 phases (init -> 10 parallel cluster dispatches -> 17 synthesis sections -> 3 side artifacts -> self-review -> user review -> register). Each phase has explicit task IDs (t1_1 .. t7_4) for Tier 2 to walk through. current_phase = 0 (spec approved, not started). Hard rule encoded in [meta]: docs/artifacts/Fable System Prompt.txt is NEVER committed.
Critical-analysis track for Anthropic's Claude Fable 5 system prompt (1585 lines, the public 'Mythos' version). 10 cluster sub-reports written by Tier 3 workers in parallel, synthesized by Tier 1 into a 17-section report (>3500 LOC) with 3 side artifacts. T-shirt size: XL. Fable artifact at docs/artifacts/Fable System Prompt.txt is local-only and MUST NOT be committed (per user hard rule). No day estimates (per conductor/workflow.md §Tier 1 Track Initialization Rules).
Final grep: 0 send_result in active code. 3 historical refs in
error_handling.md (intentional, in the 'Historical deprecation' note).
Test verification: 100/101 tests pass in the 26 files renamed by this
track. 1 pre-existing failure in test_headless_service.py due to
missing credentials.toml (verified against origin/master baseline
where it also fails - unrelated to the rename).
