Build (terra round, snapshot10g, gpt-6.1-terra/high): 10/10 pass, no product defects.
Re-run by reviewer: a1 node --test 6/6, a2 tsc+vite build ok, a3 tsc+vite build ok (same hashes), a4 14/14, a5 6/6 + build ok, a6 CRUD curl ok, a7 check.mjs 4/4, j1 npm test 8/8, j2 20/20, j7 8 planet rows.
OpenAI checks: call_* ids pair 1:1 in frames and sessions; every assistant message stores encrypted reasoning continuation and all 151 match history (replayed); cached/cache-write tokens are inside input_tokens and subtracted once (ratios 0.80-0.93); every cost matches recompute at $1/$5/$0.05/$1.25; no request crossed 272K; no 429, no retry statuses, no stream errors.
snapshot10g failureText confirmed live: single 'Error:' prefix (a6, a7); TimeoutError keeps its name (j1 subagent).
Notes: a5 seed still damaged by harness printf (harness). a3 dist/ build output not in outputs list (deliberate filter, low confidence it matters). a1 model wrote /tmp/build-sol.py outside project (bypass mode). a7 8542-byte FileWrite chunk correctly rejected (8 KiB limit), resent smaller.
LATENT (not observed): chatStream emits text deltas from several message items as one text while assistantItems joins native message texts with '\n'; a response with two message items would fail the match and silently drop its reasoning replay. Low confidence. -> verify in code.
