Reviewer summary

Adds one command for contributors to check the localization catalogs. It runs the existing checks in a predictable order and gives a short failure message.

What changed

  • add ./scripts/localize-changes as the normal contributor entry point for localization work
  • detect changed Swift localization calls and directly edited macOS catalog keys from the current diff
  • derive macOS locales from the existing catalog validator and web locales from web/i18n/routing.ts
  • prepare simple new keys with minimal catalog edits, mark only unchanged translations stale after English source changes, and emit a deterministic machine-readable work packet under git metadata
  • import completed macOS rows through the existing localization_catalog.py merge path, then run the existing strict check validator
  • report changed/missing/stale web-message work across every router locale
  • update contributor guidance that still named only English/Japanese web catalogs

The workflow deliberately stops for ambiguous catalog ownership, unsupported Swift literal forms, and new count-like strings that need explicit plural authoring. Existing placeholder, plural-category, bidi, omission, identity-translation, copied-English, and catalog validation semantics remain authoritative.

Tests

Adds focused coverage for:

  • locale discovery
  • new/missing key preparation
  • placeholder preservation via the existing merge validator
  • explicit plural authoring and Arabic plural-category validation
  • stale/partial translations
  • deterministic minimal catalog edits
  • web missing/stale locale work
  • end-to-end success/failure reporting

The focused test file is wired into the existing macOS localization tooling CI step.

Summary by cubic

Adds ./scripts/localize-changes as the standard contributor entry point for localization work. It detects changed Swift localization calls and directly edited macOS catalog keys from the current diff, prepares or flags translation work, and routes completed entries through the existing localization_catalog.py merge and strict check validators.

Workflow

  • Derives macOS locales from localization_catalog.py and web locales from web/i18n/routing.ts; writes a deterministic work packet under git metadata.
  • Prepares new simple keys with minimal catalog edits, marks only untouched translations needs_review when an English source changes, and remembers confirmed packet rows so a still-correct translation is not marked again.
  • Reports missing, stale, extra, and locale-only-deleted web-message entries across every router locale.
  • Stops for ambiguous catalog ownership, conflicting defaults at changed or unchanged call sites, unsupported Swift literal forms, and new count-like keys that need explicit plural authoring; repeated calls with one key and default no longer raise attention.
  • Batches catalog edits so each catalog is parsed once per run, and validates completed work-packet targets before writing changes.

Validation

  • Keeps existing placeholder, plural-category, bidi, omission, identity-translation, copied-English, and catalog checks authoritative.
  • Adds focused tests for locale discovery, catalog insertion determinism, plural handling, stale translations, packet safety, web work, and default conflicts across call sites.
  • Runs the new tests in the existing macOS localization CI step.
  • Updates contributor guidance to cover web locales declared by web/i18n/routing.ts instead of only English and Japanese.

Written for commit 4a6b240. Summary will update on new commits.

Merge Risk: 🟡 Moderate · up to d58ea

The documented contributor workflow can remain blocked for valid repeated keys and become materially slow for multi-key changes, so it should be corrected before merge.

Full details: Docstring Coverage

Explanation

Docstring coverage is 4.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 50 functions across 2 files. (4 skipped: 4 unsupported.)

Full details: Cmux Algorithmic Complexity

Explanation

The new production workflow rescans and rewrites a full catalog once per changed Swift key. In scripts/localize_changes.py:344, prepare_macos calls insert_catalog_entry inside the message loop. That function parses the full catalog at lines 256-258, validates the updated full catalog at lines 267-269, and writes it. Line 346 then parses the full catalog again for each inserted key. Existing-key updates at line 348 have the same per-key full-catalog behavior through update_simple_source. For K changed keys and N catalog records, this creates O(K·N) parsing and writing work, with additional growth from repeated insertions. The repository already contains a 6,580-entry macOS catalog, and the workflow has no bound or benchmark for larger batches. This matches the rule's per-target rescan condition. The change is causal because main calls prepare_macos for the detected batch of changed Swift messages.

Resolution

Refactor prepare_macos to group work by catalog path, load and parse each catalog once, and apply all insertions and simple English-source updates in one in-memory edit set per catalog. Write and validate each catalog once. Update the in-memory key index after each planned edit instead of calling catalog_entries again at line 346. Add a regression test with multiple new or changed keys in one large catalog that asserts one parse/write pass, or provide a documented bound and benchmark if a slower path is intentional.

RetriggerConfidence Score: 4/5

The PR is not yet safe to merge because an untouched unsupported Swift call site can evade the new conflict check and allow a conflicting catalog source to be prepared.

Findings

  1. P1 Untouched Conflicts Are Missed ▶

Summary

Adds a one-command localization contributor workflow that discovers changed macOS and web messages, prepares catalog work, imports completed translations, and runs strict validation.

  • Adds repository-wide Swift localization-key conflict detection and persistent translation confirmations.
  • Adds web catalog parity checks across router locales, including non-string message leaves.
  • Adds focused tests and wires them into localization CI.
  • Updates contributor documentation to describe the workflow and authoritative locale sources.
  • The repository-wide Swift conflict check still misses unsupported call forms in untouched files because their parser diagnostics are discarded.

- Around line 173-177: Update parse_swift_messages to track every matched Swift
localization call with a handled counter incremented for each SWIFT_CALL match,
including duplicate keys. Compare markers against handled rather than
len(messages), and use that difference in the attention message so correctly
processed repeated calls do not create outstanding items.
- Around line 344-348: The prepare_macos flow should batch insert_catalog_entry
and update_simple_source operations per catalog, parsing and writing each
catalog only once. Retain the resulting parsed catalog entries and pass or reuse
them in extract_changed instead of reparsing per changed key, while preserving
existing update behavior and adding coverage for batched catalog and entry reuse
paths.

Failing coverage for the confirmed review findings:

- a changed default that conflicts with an unchanged call site (same
  diff or untouched file) is silently written to the catalog
- a same-file default conflict still prepares the first default
- repeated calls with one key and one default raise permanent attention
- locale-only deletions of list-valued web messages pass parity
- a translation confirmed unchanged through the packet is marked
  needs_review again on every run
- prepare_macos and extract_changed reparse the catalog once per key

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
- Conflicting defaults: a changed key is compared with every other call
  site (unchanged calls in the diff and untouched files found with one
  git grep). Disagreeing defaults become a human-attention item and the
  key is left unprepared; a same-file conflict no longer prepares the
  first default.
- Repeated calls with one key and one default no longer raise the
  "cannot safely prepare" attention item; matched calls are counted
  instead of unique keys.
- Web parity treats list-valued messages as leaves, so a locale-only
  deletion, an extra key, or an untouched list after an English change
  is reported.
- A translation completed through the packet is remembered under
  "confirmed" and is not marked needs_review again while it still holds
  the confirmed text, so a translation that stays correct can finish.
- prepare_macos batches inserts and English edits per catalog and
  extract_changed parses each catalog once. 40 keys against the 16 MB
  app catalog: 150 s before, 3 s after.

P1 Untouched Conflicts Are Missed

When a changed localization key also appears in an untouched Swift file using an unsupported form, such as the repository’s common L10n.string("key", defaultValue: ...) wrapper or a String(localized:) call without a literal default, the new search finds the file but discards its parser warning. Because conflict detection only considers successfully parsed messages, the workflow can prepare one default and report success without detecting the conflicting call site.
