v0.9.2: multi-seed replication appendix (honest update per SEED_PLAN.md)

Documentation patch over v0.9.1. Ships the multi-seed replication that SEED_PLAN.md (locked 2026-06-25) committed to running. No code changes; no methodology changes. The result is published verbatim per the pre-registered acceptance criteria.

The v0.9 +10.2 pts paired delta (single trial across 49 paired SWE-bench Verified instances) does NOT replicate on a pre-registered 17-instance subset at seed 2. Load-bearing replication is 0 of 7 instances. Mean paired delta across both seeds is +0.24 per instance with bootstrap 95% CI [0.00, 0.47]. The v0.9 single-trial result was substantially attributable to an unlucky baseline draw rather than constraint effects alone.

The wedge claims at the architectural level (lifecycle-hook capture, per-fact provenance, per-evidence-type decay, PreToolUse defer) are unchanged. The empirical headline is honestly bounded.

The methodology discipline held: pre-registration prevented goalpost-moving; the honest update is shipped per the locked SEED_PLAN.md acceptance criteria.
