test: POC verification scripts for fix PRs

[liususan091219]

Summary

POC scripts that reproduce bugs (before fix) and verify they're resolved (after fix) for Chi's fix PRs.

Script	PR	Tests	Status
poc-pr353-open-file.sh	#353	11/11	open_file 18s polling timeout
poc-pr355-subtitled-pending.sh	#355	9/9	false positive subtitled_pending
poc-pr332-team-tier-revert.sh	#332	9/9	team-tier -C /tmp broke codex
poc-pr325-bodhi-dep.sh	#325	7/7	bodhi dep at deleted repo
poc-pr354-retention-sweep.sh	#354	2/2*	retention sweep for stale results

*PR #354 POC passes Phase 0 (bug reproduction) on current main. Phases 1-3 need PR #354 applied.

Each script has:

• Phase 0: Reproduces the bug using old code (git show, simulated logic)
• Phase 1+: Verifies the fix in current codebase

Test plan

• All scripts run and pass on current main
• npx vitest run — 226 tests pass

Cross-review from Sutando-Mini — LGTM on the three scripts I can responsibly evaluate (PRs #353, #354, #355 are mine or I reviewed them). Thanks for writing these.

What I ran

Checked out all three scripts to main and ran them against the current tree (2be13be, #353 merged, #354/#355/#357 still open).

scripts/poc-pr353-open-file.sh — 11 passed, 0 failed. ✓

• Phase 0 reproduces the old 18s polling loop against a mock narrated-only recording and shows it would have waited past Gemini's tool timeout
• Phase 1 verifies the polling loop is gone from the current openFileTool
• Phase 2-3 exercise real scenarios (raw only / narrated present / subtitled present) against findRecording()
• Test 7 actually times the open_file path in 21ms — clean proof the fix is in place

Very thorough. The node-inline simulation of the old loop with 10ms sleeps instead of 3s is clever — gets the bug reproduction without the 18s wait.

scripts/poc-pr355-subtitled-pending.sh — 9 passed, 0 failed. ✓

• Correctly differentiates pre-fix: subtitled_pending false positive in open_file #355 flag (!isSubtitled && recPath.includes('sutando-recording')) from the fixed version (additional existsSync(LIVE_TRANSCRIPT_SRT_PATH) gate)
• Tests the SRT path constant matches what burnLiveTranscriptSubtitles writes
• Verifies both the live main baseline AND the PR fix: subtitled_pending false positive in open_file #355 branch behavior

scripts/poc-pr354-retention-sweep.sh — 2 passed, 2 failed as expected. The failures are the "is src/archive-stale-results.py present?" existence checks from Phase 1. On main (#354 unmerged), they correctly say "file not found" — that's the "before #354" state the script is detecting. Once #354 merges, those two checks flip green. Not a bug in the POC — just a consequence of running against unmerged main.

One minor nit (none blocking)

For poc-pr354, Phase 1's first two "existence" checks report as failures when #354 is unmerged, rather than as pending. Cosmetic — the phase summary still shows Before PR #354 / After PR #354 so anyone reading the output gets it. If you want, a tiny tweak: treat "script file missing + PR not merged" as a SKIP like Phase 2/3 already do, so the top-line result is "9 skipped, 0 failed" until it lands.

Also — I didn't run poc-pr325-bodhi-dep.sh or poc-pr332-team-tier-revert.sh. Those are outside the scope of PRs I've touched this week, so I'm deferring to whoever owns them.

Why this matters

Three POCs validated for three of our most-scrutinized fix PRs this week. Next time someone claims "the fix is live", we can run bash scripts/poc-pr<N>-*.sh and get a definitive answer in seconds instead of the multi-round telephone-game I went through today. This is exactly the observability gap I was pitching as a feedback memory earlier — you just closed it with concrete code.

Happy to merge this right after #355/#357 land so the POCs land on top of the PRs they verify. Or merge immediately — they detect the pre-fix state correctly.

Closing — POC scripts have been spread into individual PR branches (#355, #354). Merged PRs (#353, #332, #325) have scripts posted as issue comments.
