feat: role-scoped Codex model pin and max-effort implementation dispatches - #8
Merged
Conversation
Maestro pinned one Codex model shared by read-only debates and write dispatches. Add an optional implementation model in ~/.codex/maestro-impl-model so write jobs can run on a different model, inheriting the debate model when unpinned so existing installs are unchanged. --pin gains a fourth tab field, publish_pin extends its rollback transaction to the third file, and companion_turn selects the model in the same mode branch that already selects the effort. The session-start and on-demand pickers now ask for the implementation model and carry the curated menu. Verified: tests/model-selector.sh (10 passed), tests/preflight.sh, tests/bounded-calls.sh (22 passed), plus a standalone pin-contract check confirmed red before the change.
The companion wrapper accepts only none|minimal|low|medium|high|xhigh for --effort (codex-companion.mjs:71, both cached versions), so max and ultra never reach a write job as a flag. They do reach Codex through the top-level model_reasoning_effort in ~/.codex/config.toml, which is how debate runs at max today. Write mode refused a non-expressible effort outright to avoid silently running at the debate tier. Narrow that to an exact-match rule: a write job may use max/ultra only when it is identical to the pinned top-level effort, in which case omitting --effort delivers precisely the requested tier. Any mismatch, or an unset config value, still refuses. The scout pin keeps the strict wrapper cap. Pickers now default the implementer to gpt-5.6-luna at effort max and the debate side to gpt-5.6-sol at max. Verified: tests/model-selector.sh (13 passed), tests/bounded-calls.sh (24 passed), tests/preflight.sh PASS.
📝 WalkthroughWalkthroughThe change adds a persisted implementation model alongside implementation effort. Session setup, model selection, Codex configuration, companion dispatch, pin verification, documentation, and tests now support separate debate and implementation settings.

The fake companion substituted a "high" effort whenever --effort was absent from the recorded argv and never emitted request.write, so the accept branch in companion_verify_pin for a max/ultra write that legitimately omits the flag was unreachable from the suite. Make the fixture faithful: requestedFlag now returns null when the argv parses but omits the flag (keeping the fallback only for an unset, missing, or unreadable file), and the status response carries request.write derived from the recorded task argv. This also fixes a latent fixture bug where a missing flag read argv[0] as its value, because indexOf returned -1. t0f now verifies both directions through companion_verify_pin: rc 0 with a matching COMPANION_CONFIG_EFFORT=max, and rc 4 plus the warning line when the top-level tier does not match. Also documents the separate implementation model pin: the roles no longer share one model, and the selector command takes <impl-model> as a fourth argument. Verified: tests/run.sh 18 passed 0 failed; tests/bounded-calls.sh 24 passed; tests/scout.sh 7 passed. Reverting only the fixture turns t0f red, confirming the new assertions can fail.

What changed
Two related changes to the Codex pin:
Separate implementation model. Maestro pinned one model shared by read-only debates and write dispatches. An optional
~/.codex/maestro-impl-modelnow lets write jobs run on a different model, inheriting the debate model when unpinned.--pingains a fourth tab field,publish_pinextends its rollback transaction to the third file, andcompanion_turnselects the model in the same mode branch that already selected the effort.max/ultraas an implementation effort, narrowly. The companion wrapper accepts onlynone|minimal|low|medium|high|xhighfor--effort(codex-companion.mjs:71, both cached versions 1.0.2 and 1.0.6), so those tiers never reach a write job as a flag. They do reach Codex through the top-levelmodel_reasoning_effort, which is how debate runs atmaxtoday. Write mode previously refused outright to avoid silently running at the debate tier; that is now an exact-match rule — a write job may usemax/ultraonly when it is identical to the pinned top-level effort, so omitting the flag delivers precisely the requested tier. Any mismatch, or an unset config value, still refuses. The scout pin keeps the strict cap.New defaults in both pickers: implementer
gpt-5.6-lunaat effortmax; debategpt-5.6-solat effortmax.Why
The implementer and the debate peer want different tradeoffs — a heavier write model with a different reasoning tier than the design discussion. One shared pin could not express that. And the
maxtier the models support was unreachable on the write side purely for transport reasons.Backward compatible: an install with no
maestro-impl-modelfile behaves exactly as before.How it was verified
