Kinneyzhang fd1210e557 fix: close repository audit findings 
Complete task002 through task016 across cache correctness, editor lifecycle, C boundaries, build and release governance, dictionary provenance, performance, interactive workflows, tests, documentation, and final cleanup.

Change Log: Dictionary Syntax and Provenance 2026-07-28

Planning

  • Added task011 and a decision gate before parser changes: replacement syntax could only be implemented if the fixed-width Elisp/C DP and lossless renderer could represent it correctly.

task011

  • Modify — ekp-hyphen.el, ekp.el

    • Count and reject slash/replacement dictionaries with a typed, cached condition.
    • Propagate unsupported syntax through the public formatter while still treating a missing optional dictionary as “hyphenation unavailable.”

  • Add/Modify/Delete — dictionaries/

    • Added a 49-entry manifest with pinned source paths, SHA-256, syntax counts, and license evidence.
    • Replaced the moving/GNU-specific updater with fail-closed POSIX check and deterministic export modes.
    • Retained Basque explicitly as a verified legacy byte.
    • Removed hyph_sa_IN.dic; the pinned upstream snapshot has no authoritative license statement for that exact hyphenation data.

  • Add — affected-language and inventory tests

    • Locked libhyphen golden expectations for Hungarian, Catalan, and Albanian, plus the Esperanto slash-pattern boundary.
    • Added the offline 49-entry checksum/inventory/license/syntax gate.

  • Modify — CI, release, public/developer/audit documentation

    • Added offline and pinned-upstream dictionary gates.
    • Replaced “every bundled dictionary works” with the exact supported ordinary-pattern contract.

  • Add — postmortem/20260728-dictionary-contract.md

    • Recorded why parser-only or renderer-only replacement support would be incorrect and why the future boundary crosses the DP/C ABI.

Validation

  • Affected languages red/green: 0/2 → 2/2.
  • Offline manifest: 49/49 pass.
  • Pinned upstream check: 49/49 normalized bytes pass.
  • Two fresh exports: byte-identical, 49 dictionaries each.
  • Full ERT: 121/121.
  • Warning-as-error byte compilation: pass.
  • Production checkdoc, updater/check shell syntax, workflow YAML, and diff checks: pass.

Behavior and Risk

  • eo, ca, hu_HU, and sq_AL now signal instead of silently using a linguistically incomplete pattern subset.
  • Forty-five ordinary-pattern dictionaries remain directly usable.
  • Sanskrit support is deliberately removed until exact license evidence exists; no compatibility shim or unverified license assumption remains.
