The reserve twin E3P-retry-storm targets gen-logs' other planted incident
(2026-07-02 auth-token-expiry 401 storm) and was authored before axis B
existed; the single concept table would have failed a compliant model.
Fixed pre-reserve-measurement without reading reserve files (incident chain
comes from gen-logs). Run-set scoring byte-identical; self-test 34/34 incl.
keying proof both directions.

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:

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).

Applies the Eval B when->then lesson to the three verified WS1 clusters:
explicit model: before every Agent call (cluster 2, cost exposure now that
CLAUDE_CODE_SUBAGENT_MODEL is removed), verify resolved model after launch
(cluster 1 policy gap), don't re-cover own ground before delegating
(cluster 3). Delegation thresholds unchanged.

- Add session-audit findings (10 stratified sessions, verified synthesis)
and E1-E4 eval-scenario backlog: docs/orchestration-audit/
- Add Phase 1 fact-sheet extractor: plugins/os-orchestration/audit/bin/extract
- Post-audit correction: Cluster 1 (all 23 spawns downgraded to haiku) was
NOT a Fable-5 harness bug — root cause was CLAUDE_CODE_SUBAGENT_MODEL=haiku
in ~/.claude/settings.json env block, set by an earlier session as a cost
measure. Removed 2026-07-06. Policy gap (no verify-resolvedModel rule)
stands regardless; E1 remains valid.

Renamed orchestration -> os-orchestration per naming convention, kept the
plugin's permissive delegation rule as the canonical global default, and
dropped cc-os's stricter local override so this repo behaves like every
other project (ADR-019).
