+## D9 — 2026-10-14 — Two 2.5 agent-improvement suggestions reviewed and rejected
+
+The 2.5 orchestration run (PASS, commit `cc9a0dd`) suggested: (1) adding a line to `pocock.md`
+about skill content looking truncated when a global `~/.agents/skills` install shadows the
+plugin-injected id; (2) adding a reminder that a non-ff ticket merge is normal (resume the worker).
+Both rejected: (1) is an artifact of one machine's pre-existing global install — on a clean machine
+the package content is authoritative, and adding environment-quirk prose costs context load in
+every session for zero general benefit (the model recovered unaided anyway); (2) is already the
+documented path in `pocock.md` step 5, which the run followed correctly — duplicating it would
+violate the no-duplicate-instructions validation criterion. Do not re-propose without evidence of
+a run failing because of their absence.
