Subject: [PATCH] test: add POC verification scripts for fix PRs #353, #355,
 #332, #325, #354
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Each script reproduces the bug (before the fix) and verifies it's resolved
(after the fix). All POCs pass on current main.

- poc-pr353-open-file.sh (11/11) — 18s polling timeout in open_file
- poc-pr355-subtitled-pending.sh (9/9) — false positive subtitled_pending
- poc-pr332-team-tier-revert.sh (9/9) — team-tier -C /tmp broke codex
- poc-pr325-bodhi-dep.sh (7/7) — bodhi dep pointed at deleted repo
- poc-pr354-retention-sweep.sh — retention sweep for stale results

+#
+# Bug #1 (PR #331 team tier): Used `codex exec --sandbox read-only -C /tmp` WITHOUT
+#   --skip-git-repo-check. Codex refuses to start from /tmp ("Not inside a trusted
+#   directory") because /tmp is not a git repo and the flag wasn't supplied.

+# Bug #2 (PR #331 team tier): Even if the flag had been present, -C /tmp only
+#   changes the working directory — it does NOT block absolute path reads like
+#   `cat /path/to/project/.env`. The sandbox is read-only everywhere.
+#
+# Bug #3 (PR #331 other tier): Same missing --skip-git-repo-check as team tier.
+#   The other tier already had -C /tmp but was equally broken.
+#
+# Fix (PR #332):
+#   - team tier: dropped -C /tmp entirely; added --skip-git-repo-check so codex
+#     actually starts; added explicit .env-refusal rule to the system instructions

+# Bug: When a recording finishes, the subtitled burn-in runs async (~30s).
+#      Before #353, open_file polled up to 18s waiting for the subtitled file.
+#      On phone calls, Gemini Live's tool-call timeout would cancel the poll
+#      mid-retry, and the model would say "I couldn't find the recording"
+#      even though the narrated file was already on disk.
+#
+# Fix: open_file now calls findRecording() once (no loop), returns immediately
+#      with the best-available version, and flags subtitled_pending=true if
+#      the subtitled burn hasn't finished yet.

+# POC: PR #355 — subtitled_pending false positive in open_file
+#
+# Bug (before PR #355): subtitled_pending is true for ALL recordings including
+# ones that never had subtitles requested. The old logic was:
+#
+#   const subtitled_pending = !isSubtitled && recPath.includes('sutando-recording');
+#
+# This returns true for any recording file, even ones where no subtitle burn
+# was ever started — causing the model to always say "subtitles are being
+# generated" even for recordings that will never have subtitles.
+#
+# Fix (PR #355): Now checks two conditions:
+#   1. SRT file exists at LIVE_TRANSCRIPT_SRT_PATH (transcript was generated)
+#   2. Expected subtitled .mov does NOT exist (burn hasn't finished yet)
+# Only when both are true does it set subtitled_pending=true.
+#
+# Usage: bash scripts/poc-pr355-subtitled-pending.sh
