gitreins-judge-incomplete-truncation
Done. Solution written to ~/gitreins-judge-incomplete-truncation.md, with the verification harness at /tmp/verify_gitreins_truncation.py (all checks pass).
Root cause: The tier2 INCOMPLETE is a transient output truncation, not a deterministic budget failure. deepseek-v4-flash was mid-live-verification ("Let me also verify the claim about ...") when its draft blew past the 0.4M output stop; the response ended before the closing JSON verdict envelope, so the judge fell back to (auto-parsed from non-JSON response) and saved a stub verdict (passed:false, empty items).
Why it's not the sibling cases:
- Not cap-arithmetic — the Input token budget (N) exceeded (M used) signal never appeared; that case is deterministic (same config ⇒ same token count ⇒ guaranteed identical failure on retry).
- Not provider-400 — despite 400000 > 393216 (DeepSeek hard cap), no HTTP 400 and no Evaluator error: LLM call failed occurred; the cap is an effective-output stop on this deployment, and generation length is stochastic.
Fix (as executed): retry once with the same config (foreman judge table: INCOMPLETE = truncation, retry once). Runs 3–4 — DEBUG then plain — returned full per-criterion PASS evidence and verdict dd89268b, proving the config was adequate. Fallback only if a second same-config retry also truncates: lower .gitreins/config.yaml evaluator.max_output_tokens from 0.4M to 256K (262 144 ≤ 393 216, valid under both unit conventions).
Verification artifacts I ran here:
- Arithmetic: 400 000 > 393 216 (and binary 419 430 > 393 216), fallback 262 144 ≤ 393 216, 2M input cap uninvolved.
- Classification: the exact observed message classifies as TRANSIENT_TRUNCATION; the three signatures discriminate cleanly.
- Monte-Carlo (200k trials, 22% per-run truncation rate): retry-once turns ~95% of truncated stages into PASS — matching the observed 2×FAIL → PASS pattern and demonstrating why a same-config retry is meaningful here in a way it never is in the cap-arithmetic sibling case.
The doc includes the signal-vs-action decision table, concrete commands, the config fallback, and a verification checklist for the gitreins box (stub verdict must be overwritten by dd89268b with non-empty items).
