- add COPYING (GPL-3.0-or-later) and license headers to all elisp
and C sources; real author/maintainer info replaces placeholders
- convert user-facing options to defcustom under new group `ekp'
(spacing internals managed by ekp-param-set stay defvars)
- autoload user commands: ekp-param-reset, ekp-clear-caches,
ekp-c-module-load, ekp-c-module-build
- ekp--load-dicts: a missing dictionaries/ directory now only
disables hyphenation instead of breaking (require 'ekp);
ekp--split-with-hyphen degrades gracefully (and resolves the
hyphenator once per call instead of once per word)
- package summary no longer redundantly says "for Emacs"
- Makefile: drop personal Windows EMACS_ROOT default; add guidance
- ekp_c/README.md: fix stale 1.1 version references (module is 1.4)
- DEVELOPER*.md: remove archive/ from file map (not in the repo)
- remove unreferenced 10 MB demo GIF

Buffers past ekp-auto-justify-lazy-threshold (20k chars) no longer
re-justify wholesale on a width change: the visible span updates
synchronously and the rest follows in polite background chunks
(run-with-timer ticks that yield to pending input). Measured on a
300-paragraph, 132k-char article: perceived latency 332 ms → 15 ms,
background completion ~0.5 s.
Fixed in the process: adjacent chunk markers shared a boundary, and
the earlier chunk's delete+insert pushed the next chunk's start
marker back over the freshly inserted text — chunks grew linearly
(2.2k, 4.9k, 7.4k… chars) and background work went quadratic (14 s).
Start markers now use insertion-type t. Regression test asserts the
chunked result equals the one-shot result property-for-property.
Also: org/markdown skip-face presets (ekp-region-org-skip-faces /
ekp-region-markdown-skip-faces), MELPA header hygiene (Version + URL
on the main file, stale Package-Requires dropped from ekp-hyphen.el),
readme notes.
67 ERT green; fuzz 300/300.

- 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.
