Finishes #376. The contributed keystroke tracker sat on the raw byte stream
and named tabs wrong five ways (every prompt, every write path, a bare Esc
eating the next prompt's first character, pasted newlines as Enter, any CSI
clearing the draft) and replaced the whole name, which dropped the case from
the tab and reset the w<n> counter. This lands the feature with each of those
closed:
- First prompt means the first: applyAutoName() flips a placeholder to
`auto` whether or not the string changed. nameSource is now the tri-state
placeholder | auto | manual; the name setter is the only manual path.
- Only user-originated input counts: write()/writeViaMux() take
SessionWriteOptions.fromUser, set by the browser WS path and POST /input
only, so Ralph, respawn, cron, approvals and the trust-dialog keys can
never name a tab. A startMode 'shell' CLI never feeds the tracker (a
capability, not an id check); the send-key route feeds trackUserInput()
because its line feed bypasses the session.
- Prefix form `w3-case: title`: parseSessionPrefix() already renders it as
the title with the prefix in the tooltip and the next-session counter
still matches it. Composed within MAX_SESSION_NAME_LENGTH.
- Tracker rules per key: bare Esc resolves at chunk end; mouse/focus
reports, Tab, cursor keys, Shift+Tab are no-ops; Up/Down and Ctrl+P/N/R
taint the draft so Enter submits nothing rather than a fragment;
bracketed-paste newlines and Ctrl+J / Shift+Enter join with one space;
the draft keeps its head past 8192 code points; an escape past 64 bytes
is abandoned.
- Title: slash commands by shape (a path is a prompt), `!` escapes
refused, first sentence only past 8 code points ("e.g." is not a title),
72 code points on a word boundary.
- Synced `autoNameSessions` setting, default OFF (the prompt reaches
mux-sessions.json, session:updated and /api/search), App Settings ->
Appearance -> Tabs, read fresh per prompt after the eligibility check.
Tests: test/session-auto-name.test.ts (tracker, title, composition,
ownership, emit gating), the wiring test (once, prefix, setting off,
manual protected), test/routes/session-name-routes.test.ts (PUT /name
flips to manual and persists). Verified live on an isolated instance: API
and browser-typed prompts name the tab, a second prompt does not, shells
and renamed tabs are untouched, nameSource survives a restart.
