Normalize size units and intrinsic sizing across Elisp and native layout. Add help, pointer, hover-style and keymap support with reusable interaction adapters.
Keep content updates local, preserve scroll caches and hover borders, and avoid rebuilding retained plans and ownership metadata for stable geometry.
Validation: make check and native-rust-tests passed; targeted native interaction and scroll publication regressions passed.
Reconcile duplicated native ancestry against the verified equivalent base. Preserve current source ownership, scroll partition, allocated owner rendering, and later retained-state repairs while adapting their consumers and existing fixtures to persistent runtime indexes.
Validation: strict byte compilation of 28 source files, static syntax across 56 Lisp files, cargo check, and native release build passed. Regression suites and benchmarks were not run at the user's direction.
Compile CSS-like selectors to TP structured ASTs and make TP the sole final matcher while Ebox retains logical tree adaptation and candidate indexes. Separate logical selector types from raw runtime type counts so internal flex adapters still drive bounded scroll scheduling without leaking into selector semantics.\n\nVerified: make check EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs
Make TP the sole owner of live-buffer text-property publication, mount spans, scoped diff execution, and transaction rollback. Ebox now computes layout owners and retained surface plans, publishes handle/viewport/theme/scroll changes through TP, and keeps its mirrored runtime state transactionally consistent. Remove the former Ebox marker/index/patch executor instead of preserving a second mutation path.\n\nVerification:\n- make ci EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs\n- make package-lint-install EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs\n- strict byte compilation passed for 16 files\n- Ebox production has no tp-- private calls or marker writers\n- TP production has no Ebox dependency
Assign retained TP identity before layout and emit pure, runtime-free surface plans with exact character and text-property equivalence. Keep live publication unchanged for the staged cutover and add focused surface, package, docs, and CI contracts.\n\nVerified: make check EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs\nVerified: WERROR byte compilation for all 16 active Lisp files\nVerified: focused ebox-surface checkdoc has zero warnings
Split the verified renderer, layout engine, Grid support, native boundary, tests, examples, and paired documentation into the independent Ebox repository. Keep ETAF and application concerns outside this package.
