Rename plugins/os-orchestration -> plugins/os-context. SessionStart hook is
now a composer: globs prompts/session-start/*.md in filename order, emits one
additionalContext block, byte-identical for the existing orchestration rules
(tested), line budgets enforced (warn 120 / refuse 240). ORCHESTRATION.md ->
prompts/session-start/10-orchestration.md. New prompt files from the
2026-07-09 audit: 20-kickoff-conventions, 30-standing-safety,
40-decision-memos (total injection 102/120 lines). os-status audit-skill and
state-path references updated (old ~/.local/state path symlinked;
OS_ORCH_AUDIT_LEDGER name kept for compatibility).

Grid (36 reps + 2 canaries, all counted): negatives 18/18 both tiers, zero
over-triggering; positives 1/18 on delegate-at-all, but transcript
verification splits those FAILs into superior direct strategies (scripted
bulk edit, surgical greps - the audit's own justified-non-delegation shape)
vs genuine misses (haiku whole-file ingestion, per-file grind). Conditional
rules validated where engaged: 14/14 spawns explicit-model, self-report
downgrade flag worked. E2P/E3P criterion redesign pre-registered with
independently-anchored thresholds; reserve untouched. Analysis in vault:
os-orchestration-eval-baseline-grid-results.
