Reuse prepared paragraph data, safe Elisp DP states, common layout lines, and dirty-island source reconstruction for exact append commits. Simplify C int32 validation and add the frozen task030 evaluator, regressions, and decision records.
Replace the physical ekp-region renderer with ekp-buffer text-property projection backed by shared semantic layout plans and stable live-edit transactions.
Optimize the C-backed resize hot path, and add deterministic performance, ERT, GUI, fuzz, release, and documentation coverage for task017 through task032.
BREAKING CHANGE: require ekp-buffer instead of ekp-region and rename module-owned ekp-region-* settings to ekp-buffer-*.
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.
.phrase/ (phase handoffs, agent role modules) and AGENTS.md (a
personal cross-project agent protocol referencing .phrase/) are
local working files, not project documentation. They stay on disk,
untracked.

readme/readme_zh gain Typography and verbatim-protection sections
(alignment, hanging punctuation, parshape/first-line indent,
no-break characters, halfwidth kinsoku) plus the honest limitation
notes (mid-line CLREQ compression and left protrusion are not
renderable in Emacs). DEVELOPER/DEVELOPER_ZH document the break-
permission layer, alignment extra-stretch, protrusion lockstep and
per-line specs (§5.1) and the C 1.4 API surface.

Kinsoku moves from merge-based box attachment to a general break-
permission layer, the foundation for no-break spans, NBSP, verbatim
atoms and punctuation protrusion:
- tokenizer: every CJK char (punctuation included) is its own box;
the hold/attach machinery is gone. Fixes two latent bugs: a second
consecutive closer (字。」) could start a line, and an opener held
across spaces reordered box content vs the original string
- ekp--str-type: cjk-punct splits into cjk-open (Ps/Pi) / cjk-close
- ekp-para gains breaks-allowed (bool-vector) + forbidden-positions
(sparse, for C); glue at unbreakable punct gaps is nws, so
punctuation hugs its content and justification stretch no longer
opens gaps at 「x or x。
- halfwidth kinsoku: boxes consisting purely of .,;:!?)]}’”»›… may
not start a line ((&[{‘“«‹ may not end one) — an ASCII comma after
a CJK char no longer dangles at line start (old behavior violated
CLREQ)
- DP (elisp 1D, elisp loose 2D, C): forbidden gaps are skipped as
candidates while the line keeps extending; the emergency fallback
generalizes from single boxes to atomic runs (no permitted break
inside), recording real gap counts so multi-box emergency lines
render correctly
- C module 1.2: ekp-c-break-with-arrays 11→12 args
(forbidden-positions), batch vectors 12 elements, version gate bumped
Hyphenation improvement: 「Hello / Hello」 previously failed the
word regexp as merged boxes and were never hyphenated; as separate
boxes they hyphenate normally.
Tests: 48 ERT green (split tests migrated to the new box contract;
new unit test for break permissions and a rendered-output kinsoku
sweep across widths); 300-case fuzz 0 failures with C 1.2 parity.

- fix: ekp-param-set silently reset after first justify (now persists;
ekp-param-reset added)
- fix: narrow-width CJK returned empty string (data loss); two-pass
emergency-break strategy guarantees output for any input
- fix: K-P penalties never synced to C module; space-box metrics
divergence between C and Elisp engines
- fix: para cache ignored ekp-latin-lang (stale hyphenation after
language switch) and used collision-prone sxhash keys
- fix: fullwidth letters/digits misclassified as CJK punctuation
- fix: combining chars split from their base char in the tokenizer
- fix: punctuation-wrapped words (word!/(word)/word;) never hyphenated
- fix: renderer double-counted stripped space widths; negative glue
clamped; batch/tty font detection no longer crashes
- feat: real looseness support via (position × line-count) DP
- perf: O(1) line metrics and gap counts via prefix arrays (inner loop
previously allocated O(n) subsequences → O(n³) total); box measurement
dedupe; eq fast-path para lookup; prebuilt per-para glue arrays
→ zh justify 7547ms → 96ms (compiled elisp) / 57ms (C);
range-justify 68.5s → 0.48s / 34ms; C module itself 3–19× faster
- test: 36 batch-safe ERT tests + 300-case property fuzz (C/elisp
byte-identical output, zero content loss) replacing ad-hoc suite
- docs: readme/readme_zh/DEVELOPER/DEVELOPER_ZH/ekp_c-README rewritten
to match the implementation; phase handoff in .phrase/phases/
BREAKING: requires Emacs 29.1+; C module must be rebuilt (v1.1, new
arities); ekp-threshold-factor / ekp-flagged-penalty /
ekp-forced-break-penalty removed; Rust module stubs removed.
