Status header: Analyze -> Plan.
Baseline findings folded into the design sections:
§1 (highlighter pillar) gains B4: tree-sitter absent on every
probed host; :highlight on emits install-hint when missing.
§4 (highlighter sketch) revised per B3: io.popen():close() doesn't
expose exit codes in LuaJIT. Route via executor.exec("cat tmp |
tree-sitter ...") which uses pty.spawn+waitpid and returns code
reliably. Tmpfile design retained (avoids ARGMAX + shell-escape).
§5 (:diff impl + @<r1>..<r2> retry) revised per B1: every git
invocation must use `--no-pager -c color.ui=never` to suppress
the color/keypad/line-clear escapes forkpty triggers. Factored
recommendation: helper `_git_clean_cmd(subcmd)` shared by :diff
and the @-mention diff retry.
New §12 Implementation Plan — 6 commits, bottom-up:
1. context.lua: ctx.project + compose_project + composition order
2. repl.lua: _scan_project_tree helper + :tree meta
3. repl.lua: :diff meta + _git_clean_cmd helper (B1)
4. repl.lua: expand_mentions tiered resolution (@<r1>..<r2> per A6)
5. renderer.lua + repl.lua: tree-sitter detect + fence filter +
:highlight meta (B3-revised tmpfile dispatch)
6. config.lua project example + status -> Implement
Per-commit risk index + smoke criteria. Highlighter (commit 5) is
the largest experimental surface — placed last so the rest of Phase 6
ships even if highlighter slips. Order is independent enough that
swapping 3<->4 or 5<->6 doesn't break anything; bottom-up keeps each
commit individually green.
Things deliberately not split: _shq reuse, lang map duplication for
v1, streaming-rehydration order (rehydrate -> highlight -> emit
inherits naturally from existing chunk pipeline).
Two items open at plan time, resolve at implement: _scan_project_tree
dir-arg vs hardcoded getcwd; :highlight status probing
tree-sitter --print-langs.
