Bridge 0.10.3

Bridge 0.10.3

Bridge 0.10.3 is a patch release on 0.10.2 that carries out Group A of the
September simplification audit: dead protocol layers, unused modules and
point-in-time documents are removed, and two small performance fixes land.
Nothing about the on-disk project shape, the three schema ladders, the
correction ledger, the goldens or the confidence thresholds changes; a project
created by 0.10.0, 0.10.1 or 0.10.2 opens unchanged.

What was removed

Every item below had no caller in the UI, no importer in the engine, or both.
Each was re-verified against the code before deletion; the ones where the audit's
claim turned out to be incomplete are noted.

• 13 engine methods no Tauri command could reach (#102):
  project.sweepStart/Status/Cancel, semanticMapping.getForVerse/confirm/rerunForVerse,
  versification.detect/orgRef/backVersificationMap,
  alignment.corpusStats.summary/forVerse, verse.evidence, and the sweep job
  manager behind the first three. The modules they wrapped stay: versification
  (used by the Stage 4 runtime), alignment statistics (behind the live
  inconsistent-rendering finding, whose cache and invalidation are untouched)
  and the Stage 3 modules.
• ai.explain (#105), a synchronous duplicate of what the ai.review job
  does per verse, with no UI caller. Its selection-gate tests now drive the live
  ai.review.start job instead, with unchanged assertions.
• 47 protocol methods' Rust and TypeScript layers (#103): every Stage 4 to 8
  direct-access method except the two range getters the Alignment Review
  passage view uses, plus saveAlignment, completeAlignment,
  alignmentBackups, logos.*, paratextSetReference, triageClear,
  scanProject and projectCollectionReport. The Rust shell goes from 137 to
  90 commands, the client from 137 to 90 methods. The 1,491-line Rust mirror of
  the passage-semantic types (passage_semantic_wire.rs) is gone; the JSON
  schema it mirrored stays. The engine handlers all stay: the Stage 5 to 8 tests
  drive them by method string, and Logos remains reachable through
  navigation.*.
• Five engine modules with no importer (#104): the two machine-proposed
  benchmark evaluators, the Paratext registry HTTPS client, the Tk caret helpers
  from the legacy tool, and the Git identity reader. The benchmark datasets stay
  bundled.
• The corpus-discovery generator behind the finished IRVTam review (#101),
  and the dead showSource store (#106).
• Docs: six point-in-time review documents and HANDOFF.md moved to
  docs/archive/ with an index (#107). About 5.9k lines leave the reading
  path; nothing is deleted, and every inbound link is re-pointed.

Performance

• The desktop navigation poll no longer round-trips while sync is off
  (#110). The 800 ms tick used to cross Rust, stdio and Python about 75 times a
  minute even with neither Paratext nor Logos enabled. It now returns before the
  request unless a connector is enabled. Enabling sync in Settings starts the
  round-trips on the next tick, as before. This is verified from the code and
  the test suites, not yet in the installed app; the issue stays open for that
  check.
• project.open has a 180 s timeout (#112 step one) instead of the 30 s
  default, the same class as project.inspectImport, so a slow or scanned disk
  cannot make the shell give up while Python is still opening a book.

What stayed, on purpose

• The Stage 3 semantic-mapping engine and the AI alignment-proposal path.
  Their removal is a separate recorded decision (#109) and is not in this
  release.
• The four collection-report entry points (#108), likewise.
• verse_evidence.py now has no importer outside its tests; whether it is
  the intended shared evidence shape or dead is #120.
• Six more caller-less client methods and sixteen unused TypeScript exports
  the audit did not name are recorded in #121, not removed here.

Known limitations

• One commit reached main with a failing engine test (the #103 batch
  deleted a Rust file that one Python test read as text); the fix followed in
  the same session and main is green again at the commit this release is cut
  from. The lesson is recorded in docs/BUILD_LOG.md.
• The frozen-sidecar smoke check lost its versification, corpus-stats and
  ai.explain blocks with their methods; it still stops at the pre-existing
  project.inspectImport duplicate-classification mismatch, so the release
  workflow's smoke step remains continue-on-error.
• 0.10.0's upgrade rules still apply: a project holding any pre-cutover file
  store refuses to open and must be re-imported. See RELEASE_0.10.0.md.
