What changed

One commit on this branch, and it is documentation only. Codex and Greptile left 15 unresolved review findings (1 marked P1) on the experiments code after PR #239 merged into alpha. I re-verified each finding against alpha head 969d4e93 and found all 15 already fixed by earlier merged commits, each with a regression test that still passes. Acting again would have duplicated work that is already in, so there is no production change to make. The single commit (3be42cd6) adds experiments/PR-239-REVIEW-DISPOSITIONS.md, the in-repo record of that disposition table; a branch identical to alpha cannot open a compare pull request, so the record is committed to make this PR exist at all. No production code, tests, or workflows are touched.

Why

The replies on the review threads already name fix commits, but replies can go stale or be wrong, so I did not take them at their word. I read the current code behind every finding — the blind ranking path in meter_eval.locate, the serial contract in meter_eval.match, the atomic write in capture_contract.py, the session/output containment and scored-symlink handling in evals.field, the stage-ownership recovery in rename-fixtures.py, and the capture_s definition in scoring.measure_lab — and then ran the suites. The fixes are real, independent of the replies, and covered by tests whose names match the findings. The committed record keeps those resolutions citable next to the code they describe; it documents the six areas directly below experiments/, which is why it lives there rather than in any one package.

Review findings disposition

Finding Disposition Fixed in Covered by
P1: rank candidates without consulting the label already-fixed-on-alpha 43698f23 tests/test_serial_contract.py::test_field_cli_reports_the_blind_second_rank_and_uses_the_blind_box; evaluate() now calls candidates(result) with no digest, orders with ranked(found), and compares the target only after ordering
Preserve output permissions during atomic replacement already-fixed-on-alpha 7b5529dd test_contract.py::test_atomic_replacement_preserves_existing_permissions, ::test_new_result_permissions_follow_umask; write_result fchmods the staged inode to the old mode before replace() and stages new outputs in a private temp directory
Reject cleanup paths nested inside directory sessions already-fixed-on-alpha d8573f02 tests/test_field.py::test_score_preserves_directory_sessions_overlapping_outputs; score() checks is_relative_to in both directions between every directory input and the output root, scored, and each generated file before deleting anything
Remove or reject a symlinked scored directory already-fixed-on-alpha 4e098eb5 tests/test_field.py::test_score_replaces_scored_symlink_without_touching_its_target (live and dangling cases); score() unlinks the scored symlink itself, then creates a real directory
Remove the blanket commercial-license claim already-fixed-on-alpha 01ec183f Documentation change, no test; verified by reading: models/README.md now opens with "MoGe-2 is excluded from commercial-use claims until its checkpoint licence is verified" and the table row says "weights unverified"
Reclaim fixture stages after every hard exit already-fixed-on-alpha 7b5529dd test_fetch_fixtures.py::test_failed_refresh_preserves_existing_fixtures, ::test_overlapping_refresh_waits_before_recovery; fetch-fixtures.sh runs recovery first and calls --mark-stage immediately after mktemp, before archive or extraction
Verify stage ownership before recovery cleanup already-fixed-on-alpha 01ec183f test_fetch_fixtures.py::test_recovery_preserves_unknown_fixture_stages, ::test_recovery_preserves_a_stage_without_a_marker; recovery validates marker shape and stage/backup device-inode identity and leaves unknown paths untouched
Preserve backups when recovery finds an occupied destination already-fixed-on-alpha d8573f02 test_fetch_fixtures.py::test_failed_refresh_preserves_existing_fixtures; recovery raises "Fixtures is occupied; backup preserved" and deletes nothing while any backup exists
Describe the field ranking as blind already-fixed-on-alpha 4e098eb5 tests/test_serial_contract.py::test_field_help_describes_blind_ranking; the fieldtest docstring now says candidates and the retake box come from the blind heuristic ranking and --number only scores
Ignore unsupported Unicode in barcode payloads already-fixed-on-alpha a2480273 tests/test_serial_contract.py::test_invalid_barcodes_do_not_abort_photo_scoring, parametrized over é1234567, 序號1234, ß1234, ff1234, and a combining accent; number_core returns None instead of raising and payload_fields skips such fields
Split barcode payloads before validating serial characters already-fixed-on-alpha a7e99b4a tests/test_serial_contract.py::test_barcode_fields_are_validated_independently, ::test_barcode_fields_cannot_join_across_a_delimiter; payload_fields splits on ;, *, ,, {, } before validating each field
Compute alone per OCR row already-fixed-on-alpha d8d31063 tests/test_serial_contract.py::test_two_number_rows_are_each_alone_and_keep_the_prior_rule_pick, ::test_row_features_use_the_source_row_and_keep_candidate_box_separate; alone comes from a per-row candidate count, not the image-wide count
Reject non-ASCII serials before compatibility expansion already-fixed-on-alpha a2480273 tests/test_serial_contract.py::test_unicode_expansions_are_invalid_as_targets_and_ocr, ::test_only_fullwidth_ascii_is_mapped; serial_text maps only ASCII and fullwidth ASCII letters and digits, with no NFKC or Unicode case folding, so ß and ff fall to invalid groups
Exclude text-only serial candidates already-fixed-on-alpha d8d31063 tests/test_serial_contract.py::test_maker_only_observation_requires_a_number_retake, ::test_maker_on_another_row_cannot_be_the_number_candidate; a joined candidate with no digit is never appended
Update the documented endpoint for capture timing already-fixed-on-alpha 01ec183f tests/test_review_debt.py::test_capture_duration_includes_last_refusal, ::test_refusal_only_session_has_capture_duration, ::test_refusal_before_start_is_rejected; FORMATS.md now reads "capture_s runs from the session's start to its last capture attempt (measurement or refusal)", matching the code that takes the max over both

Verification

Run on a fresh clone of alpha at 969d4e93 inside the existing BaseScanning repo sandbox, in a directory of my own; no other checkout was touched. The suite projects pin tool.uv.required-version >=0.11.15, <0.12, so the suites ran under uv 0.11.33; the models project has no pin and passes under both 0.11.33 and 0.13.1. The committed file is documentation, so these counts are also the alpha baseline: 1117 passed, 0 failed.

Suite (command) Result
meter-closeup (uv sync --locked + make check: ruff check, ruff format --check, pytest) 401 passed; lint and format clean
evals (uv sync --locked + make test) 259 passed; lint and format clean
evals models (uv sync --project models --locked + uv run --project models pytest -q models/tests) 46 passed
scoring (uv sync --locked + ruff check, ruff format --check, pytest) 372 passed; lint and format clean
capture-contract (python3 -m unittest -v) 19 passed
live-dots fixtures (uv run --project ../meter-closeup pytest -q test_fetch_fixtures.py) 20 passed
Test log tails
meter-closeup:  ruff check -> All checks passed! | ruff format --check -> (silent, clean)
meter-closeup:  401 passed in 3.37s
evals:          ruff check -> All checks passed! | 259 passed in 7.26s
evals models:   46 passed in 1.41s
scoring:        ruff check -> All checks passed! | 372 passed in 0.91s
capture-contract:
test_atomic_replacement_preserves_existing_permissions ... ok
test_new_result_permissions_follow_umask ... ok
test_failed_output_write_preserves_previous_result ... ok
Ran 19 tests in 0.155s
OK
live-dots:      20 passed in 3.32s

Coverage limits, stated plainly:

  • There is no typecheck target for these directories — no mypy or pyright configuration exists in meter-closeup, evals, scoring, live-dots, or capture-contract. Ruff check plus ruff format --check is the static gate the repository runs for them, and both are clean.
  • The iOS, web, server, and recon suites were not run. The branch's only change is a markdown file under experiments/, so no suite outside the six above has anything new to check; the Xcode-dependent work also cannot run in this Linux sandbox.
  • experiments/live-dots also has a Swift package whose tests need swift, which the sandbox does not have. The Python fixture-recovery suite, which covers the two live-dots findings, ran in full.

Risk

Minimal: the only diff is a new markdown record. The one material risk is misreading — if any disposition above is wrong, the review thread would be closed on a false already-fixed claim. The mitigations are that each row names the fix commit and the covering test, and that I verified the current source of every fix by reading it, not by trusting the thread replies.

Checklist

  • The scope is focused; related changes belong together
  • I explained what changed and why
  • I included before/after images for visible changes — N/A, no visible change: the only commit adds a markdown record, so there is no UI or rendered output to capture
  • I included a video for motion or interaction changes — N/A, same reason

Summary by CodeRabbit

  • Documentation
    • Added a review record for 15 findings, noting their resolution status and links to related regression coverage or documentation.
    • Recorded verification results: 1,117 Python tests passed and lint checks were clean. iOS tests were not run because Xcode was unavailable.

All 15 unresolved review findings on PR #239 were already fixed on alpha
by earlier merged commits. This file ties each finding to its fix commit
and the regression test that covers it, and records the verification run
(1,117 passed, 0 failed across the six suites at alpha 969d4e9).
