Operator rule (2026-10-05): standard is Opus 5.5 at reasoning effort High. Four retrieval agents (architecture-mapper, dependency-tracer, git-historian, task-finder) pinned effort: medium in frontmatter, which overrides the session level, so every /trekplan exploration ran part of its swarm below the floor. They came from fdd3ad8 on the premise that unpinned agents inherit high; e4e37f9 corrected that (unpinned inherits the session; Opus 5.5 defaults to medium), so the reason for medium was already gone. All four now pin high; the other agents keep following the session (operator's choice). docs/profiles.md (one bullet for the eight pinned agents), CLAUDE.md and README.md updated; the model-default sentence stays. Dated decision records and CHANGELOG untouched.
Red: 4 of 5 new tests fail on the pre-fix files - effort floor over all agents (offenders: the four), the four pin exactly high, no live doc says retrieval runs at medium (hits docs/profiles.md:76, CLAUDE.md:85, README.md:806), profiles.md names the four as high. Known-positive control green on arrival.
Verify 153/153 (agent-frontmatter, doc-consistency). SC9 probe: npm test green under a scratch HOME with CLAUDE_PLUGIN_DATA empty, nothing under its plugin data dir. Suite 1393 (1391/0/2).
The change is repo-true, not installed-true, until a release.
Voyage order 20261005T104513Z-1250514346, plan step 5/5.
