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).

Harness: 6 run-set + 6 frozen-reserve paired scenarios from the WS1 verified
misses, Node relaystation fixture (deterministic sandbox-time logs), headless
runner with CLAUDE_CODE_SUBAGENT_MODEL stub for E1P, deterministic-first
checker driving audit/bin/extract (extended with per-segment read targets),
narrow frozen haiku-judge fallback for E1 language axes, model-free self-test
21/21 incl. shipped-instruction-compliant conformance transcripts.
Wording v2: the E1 canary (counted) proved resolvedModel is not model-visible
in the launch result, so the launch-stub-comparison rule was unactionable;
replaced with subagent model self-report on sonnet/opus spawns (subagents know
their exact model ID - verified live). Scenarios/checker/rubric untouched.
Deterministic env-override detection routed to WS3 (plan updated).
