Repair21 — source submission; tests NOTRUN

P04-01 source-only performance repair. Changes are restricted to the checker, the new bulk_reader_equivalence.py fixture, and this status file. No Git command, test, fixture, collector, Runner, native/Godot run, agent, commit, branch or integration operation was executed by the worker.

read_blobs validates full lowercase 40-hex OIDs before starting a process, deduplicates/sorts them, and uses one git cat-file --batch process per nonempty request. Empty requests start no process. check_output inherits stderr and raises for nonzero exit status just like git_bytes. The separately injectable byte parser verifies ordered OIDs, blob type, decimal size, exact framing and complete output consumption. There is deliberately no blob cache, so no object can be reused across _GIT_ENV namespaces. The two bulk call sites preserve selected-path sorted manifests and every actual-file byte/mode comparison.

No existing require message or assertion was removed. The NATIVE_RUNS through verify_native region, commit-type checks, ancestry, merge-tree isolation, status/untracked/symlink/module checks, schema/encoder, six existing suites and role case IDs were not edited. Checker self-blob reads remain unchanged.

The fixture source covers binary NUL/CR/LF/trailing LF, empty and large blobs, unicode ls-tree -z path resolution, duplicates, empty input, malformed/short OIDs, missing objects, tree/commit objects, invalid/truncated/oversized/garbage responses, process failure, one-process sorted input, and private object visibility inside versus outside and across isolated namespaces. It has not run.

Static validation: ast.parse and in-memory compile(..., 'exec') completed for the checker and new fixture. Neither module was imported or executed. This is syntax validation only. Tests: NOTRUN. Runtime equivalence and completion within the registered 180 seconds remain for Root to measure.

The existing schema2 index at B/p04-evidence/index.json was read as data, along with the existing builder and role fixture. Its registered/execution/tested roles remain deb1bcb/9767b0a/5f6bc11 and original_credit remains 13/88. The existing index and r20 collection are untouched. No new generation is needed if Root confirms the recomputed payload is identical. If generation is needed, use a new explicit destination, never overwrite existing evidence. Original P04-01 remains incomplete; criteria and nativeWindows pending status are unchanged. No original credit or acceptance is claimed.

Root execution order — all NOTRUN

Use the clean new auto-submitted checkout, whose SHA is assigned after this source submission. Do not use the registered base SHA as the new submission.

python3 "$E/checker_join_fixtures.py" --build "$B"
python3 "$E/checker_role_fixtures.py" --build "$B" --evidence "$B/p04-evidence"

Next run the registered validation on the new auto-submitted SHA, retaining its existing 180-second timeout and actual timed receipt. The supplied formal API call is exactly:

runner.validate("P04-01")

The external Runner launcher/configuration is not present in the supplied task context; use Root's already registered invocation, without substituting an invented CLI, changing timeout, or treating direct checker timing as registered validation. Record actual SHA, elapsed time and exit status from that invocation.

Then run direct real-candidate controls from actual clean submitted, merged and final checkouts, preserving the formal review/integration state machine:

python3 tools/check_p04_order_evidence.py --verify-only
python3 "$P04_MERGED_CHECKOUT/tools/check_p04_order_evidence.py" --verify-only
python3 "$P04_FINAL_CHECKOUT/tools/check_p04_order_evidence.py" --verify-only

After required formal validation/review and exact final-source binding, run the full178 product regression once, using a fresh output destination:

python3 "$P04_FINAL_CHECKOUT/tools/run_all_tests.py" \
  --project-root "$P04_FINAL_CHECKOUT" --output "$B/p04-final-product-full-r21"

Do not regenerate raw collections, overwrite index/r20 evidence, alter existing case semantics, or run an additional native/full suite to compensate for a timeout. Any unrelated improvement is deferred. Pending Root execution is not a worker specification gap and does not change this submission's scope.
