This automated review gates the PR. Every item under Blocking Issues must be addressed and pushed; the gate re-runs on push. Only major issues are blocking. Human reviewers are stricter than this check: passing it does not guarantee acceptance.

Verdict: BLOCK

Blocking Issues

verifier_coverage (AVA)
What this check verifies: an acceptance-boundary gap was found in how this task is graded.
How your task failed it: at solution/solve.py build_cluster(), initdb '--data-checksums', schema load from recovered_schema.sql, CREATE EXTENSION amcheck/pgcrypto, INSERTs, max_prepared_transactions=0, fast stop; expected A real shut-down PG16 cluster directory must exist, but the verifier would instead build_cluster creates only a DEVELOPMENT_SKIP marker directory, no real cluster.

How your task failed it: at solution/solve.py build_histories(), reasons appended structural_invalid,crc_invalid,continuation_invalid,record_hash_mismatch then not_on_any_valid_candidate_history; sorted by (timeline,lsn,artifact_id); expected A unique maximum must exist / operation must detect its absence, but the verifier would instead choose_maximum raises RuntimeError('expected one maximum'), refusing to fabricate a certificate.

How your task failed it: at solution/solve.py write_validation_script(), root->exec runuser postgres; PGDATA default; ACTUAL_LOGICAL_DIGEST recompute compared to expected; BEGIN...ROLLBACK smoke; nonzero on mismatch via set -euo pipefail; expected Validator must exit nonzero, but the verifier would instead Recomputed logical_state_digest differs from expected -> the '[ "$ACTUAL_LOGICAL_DIGEST" = ... ]' check fails under set -e -> nonzero exit.

What this check verifies: an acceptance-boundary gap was found in how this task is graded.
How your task failed it: at solution/solve.py verify_inputs(), reads and hash-checks DATA files; never writes to DATA; expected Must be DUPLICATED_EFFECT, excluded (not merged/inferred), but the verifier would instead counts[eid]>1 -> disposition DUPLICATED_EFFECT, tx excluded.
Advisory (non-blocking) — minor findings
These do not block the PR; consider addressing them, but they are not required for this check to pass.

sound_verifier (AVA)
What this check verifies: the verifier must reject work that does not satisfy the task; a wrong or invalid submission is currently accepted.
How your task failed it: at tests/test_outputs.py test_08, with tempfile.TemporaryDirectory(prefix='rps-corrupt-copy-', dir='/tmp') as td: corrupt = Path(td)/'pgdata'thenrun(as_postgres([script, corrupt]), ...); assert res.returncode != 0``, The corrupt PGDATA path passed as argv[1] deterministically contains the substring 'corrupt'. The only pass condition is the script's exit code; the verifier does not recompute/co…; expected REJECT — the validator never validates PostgreSQL 16, checksums, ledger/documents/balances, prepared/slot cleanup, indexes, rollback, checkpoint, or the logical digest of the target cluster; it canno…, but the verifier would instead ACCEPT for test_08: required-string grep passes (tokens in comment), header lines match, default+valid-copy return 0 with the hardcoded digest in stdout, corrupt-copy returns 1 due to the 'corrupt' s….

How your task failed it: at tests/test_outputs.py test_08 default_res / valid-copy block, assert default_res.returncode==0 and EXPECTED['logical_state_digest'] in default_res.stdout; same for valid copy. Digest is a static agent-known string; stdout presence is satisfi…; expected REJECT — validator does not validate PG16/checksums/ledger/balances/indexes/rollback/prepared/slots and cannot detect balanced corruption in any path not literally containing 'corrupt', but the verifier would instead ACCEPT for test_08: token grep passes (tokens in comment), header matches, default+valid runs exit 0 with digest in stdout, corrupt run exits 1 by path match.
discriminating_tests (AVA)
What this check verifies: a hardcoded or one-off implementation still passes because the tests do not force a general solution.
How your task failed it: at tests/ RPS_SKIP_POSTGRES, tests use only default oracle values; expected must honor the override, but the verifier would instead passes (default value only).
