Triage stranded commit 066c2ab on codex/prompt-source-precedence (pushed but never PR'd)

[s-hiraoku]

Problem

PR #165 ("Make prompt source precedence explicit") merged, but the branch codex/prompt-source-precedence was pushed after the merge with one additional commit that is not on main and has no PR:

• 066c2ab — "Include issue comments in verifier prompts"

The commit exists only on origin/codex/prompt-source-precedence. If the merged branch is pruned, this work is silently lost. (Note: issue #173/#160 territory — including issue comments in verifier prompts also has trust-boundary implications, so it deserves review rather than silent landing.)

Task

1. Decide: open a PR for 066c2ab (rebased onto current main) or explicitly discard it with a note here.
2. Root cause: work happened on a primary checkout sitting on an already-merged branch. This is the fleet-hygiene failure mode described in the 2026-07-05 v2 evaluation §5.1 — it recurred within hours of a full fleet resync. Treat as supporting evidence for prioritizing worktree isolation ([monitor] Resync kaizen-loop pr-guardian skill #87, Blocked: sync pr-guardian after upstream fix (#86) #88, Daily dogfood sync rejects Git worktree targets .github#104).

Done when

origin/codex/prompt-source-precedence contains no commits absent from main (either merged via PR or documented as discarded), and the branch is deleted.
