Frontend companion to the unified Session Manager backend merged in #139. Where the backend added the aggregated session service + list endpoint, this adds the UI that surfaces it.

What this adds

  • Welcome-screen session list — the welcome overlay renders the unified session list (live + persisted + closed history, across CLIs), newest-first with richer context, rather than only Claude transcripts.
  • Persistent Session Manager modal — an always-on header button opens a searchable modal listing every session (live + historical), with per-session mode/LIVE badges. Search filters by name, prompt, or path.
  • Live SSE refresh — the list updates in place as sessions are created/updated/removed, no reload.
  • Session-row action menu — each row's opens a context menu of per-session actions.

Scope

8 files, +502/-19 — frontend (terminal-ui.js, panels-ui.js, app.js, index.html, styles.css) plus a small unified-session-service touch and one route wire-up, and a unit test.

Verification

  • tsc --noEmit 0 · frontend-syntax 22/22 · prettier clean · unit tests 16/16 · build clean.
  • Functional check on an isolated instance (Playwright): Session Manager button + welcome list render; modal opens and populates the unified list; live session shows with a LIVE badge; search narrows the list; the row context menu opens with actions; creating a session live-refreshes the open list with no reload; no console errors.

Rebased onto current master (the #139 backend commits are now upstream), so this is a clean frontend-only diff.

Backs the welcome-screen "Resume Conversation" list with the new
GET /api/sessions/unified endpoint instead of /api/history/sessions, so it
shows the COMPLETE set (live + persisted + non-Claude + closed history)
newest-first with richer context, rather than only Claude transcripts.

- terminal-ui.js: new _fetchUnifiedSessions(); loadHistorySessions() now uses
  it. _buildHistoryItem upgraded to the unified shape (kept backward-compatible
  with the folder-modal's old shape): title = name || firstPrompt || dir; a
  mode badge + a LIVE badge (sources includes 'live'); timestamp from
  lastActivityAt (falls back to lastModified); size only when present; detail
  panel + "View all in this folder" preserved (gated on projectKey). Resume
  branches: an open live session selects its tab, a closed one resumes.
- unified-session-service.ts + endpoint: pass projectKey through the history
  source so the folder drill-down survives.
- styles.css: .history-item-badges / -badge / -badge-live pills.

Verified: tsc 0, lint 0, frontend-syntax + public-asset format clean, service
tests 13/13 (+projectKey), route tests 4/4. Playwright on an isolated beta:
the welcome list renders real items from /api/sessions/unified, and the
renderer produces the tab-name title + codex mode badge + visible LIVE badge,
omits LIVE on closed items, keeps "View all in folder", and routes resume
correctly (open->select tab, closed->resume). Persistent panel + live SSE
status are later units.
… A, unit 3)

Adds a header-reachable Session Manager so the complete session list is
available mid-session, not only on the welcome screen.

- index.html: always-on header button (.btn-session-manager) + #sessionManagerModal
  (mirrors the Away Digest modal) with a search box + results list.
- panels-ui.js: openSessionManager()/closeSessionManager()/_loadSessionManagerList()
  — loads GET /api/sessions/unified (limit 200), renders via the unit-2
  _buildHistoryItem (rich items, mode/LIVE badges, open->select / closed->resume),
  debounced search wired to the endpoint's q= param, empty/error states. A
  modal-scoped Escape listener closes it even when focus is in the search input;
  backdrop click and item click also close it.
- app.js: closeSessionManager() added to the global Escape chain.
- styles.css: modal + list styling (items reuse .history-item).

Verified on an isolated beta instance (Playwright): the header button opens the
modal, it lists 200 sessions from /api/sessions/unified, a no-match query issues
?q= to the server and yields 0 items, clearing restores the list, clicking an
item closes the modal and routes resume/select, and Escape closes it. Gates:
tsc 0, lint 0, frontend-syntax + public-asset format clean, 17 tests pass.
The complete session list now updates live as sessions change, instead of
only on open/welcome-load.

- app.js: extra SSE listeners (session:created/updated/deleted) on the same
  EventSource (multiple listeners per event; existing handlers untouched;
  registered via addListener so they tear down on reconnect) call
  _onSessionListMaybeChanged().
- panels-ui.js: _onSessionListMaybeChanged() debounced-refreshes the Session
  Manager modal when it's open and the welcome list when its overlay is
  visible (no work when neither is showing). _loadSessionManagerList stores the
  active query so refreshes preserve the user's search.

Verified on an isolated beta instance (Playwright): dispatching a session
event refreshes the modal while open, does NOT while closed (gated), and
refreshes the welcome list while visible. Gates: tsc 0, frontend-syntax +
public-asset format clean, build clean.
The per-row ⋯ in the session list was a details toggle that did nothing in
the Session Manager modal (swallowed by the modal's capture-phase
close-on-click). Replace it with a real kebab context menu.

- terminal-ui.js: ⋯ now opens _openSessionRowMenu() — a body-anchored popup
  (fixed-positioned, flips/clamps to viewport, z-index above the modal) with:
  Resume/Switch-to (live→select tab, closed→resume), Open folder in the file
  browser (live sessions only — the browser is session-scoped), Copy path
  (_copyText + toast, when workingDir present), and Show details (the old
  inline prompt/path panel). Closes on outside-click / Escape / scroll / resize.
- panels-ui.js: _loadSessionManagerList scopes its modal-close to the
  .history-item-main (resume) click, so the ⋯/menu no longer closes the modal.
- styles.css: .session-row-menu + .session-row-menu-item.

Verified in Chromium on an isolated beta: ⋯ opens the menu with the modal
still open; closed rows show Resume/Copy path/Show details, live rows add
Switch-to + Open folder; Show details expands inline (modal stays open),
Copy path copies the path, Resume closes the modal, Escape closes only the
menu. Gates: tsc 0, lint 0, frontend-syntax + public-asset format clean.
Resolve the 4 conflicted files toward master's merged Ark0N#146 work while
keeping PR Ark0N#153's genuinely-new additions:

- app.js: keep the full Escape chain (closeSessionManager +
  closeCommandPalette + closeShortcutOverlay).
- index.html: keep master's Command Palette modal markup alongside the
  PR's Session Manager modal + header button.
- styles.css: keep master's Command Palette + COD-157 shortcut CSS AND
  the PR's COD-130 session-row kebab-menu CSS (both inserted at the same
  spot — reunited each with its own closing brace).
- terminal-ui.js: resolve _buildHistoryItem's main-row click handler to
  master's options.onActivate contract with a liveness + claudeSessionId
  -aware resume default, preserving the PR's two-shape/badges/kebab body.
- panels-ui.js: the PR's pre-Ark0N#146 Session Manager block auto-merged as a
  duplicate AFTER master's fixed block (last-key-wins regression) — drop
  it, keep master's implementation plus the PR's new
  _onSessionListMaybeChanged.

Backend projectKey plumbing and the SSE live-refresh listeners in app.js
merge additively and are kept as-is.
…implementation (PR Ark0N#153)

- Hide the new btn-session-manager header button on phones: add it to the
  @media (max-width: 430px) display:none block in mobile.css (next to
  .btn-away-digest) and to KNOWN_PHONE_HIDDEN in the mobile-header policy
  test, closing the recurring phone-header-leak regression that was PR
  Ark0N#153's red CI job.
- Put the session-manager header button on its own line in index.html
  (was crammed onto the away-digest line).
- app.js: drop session:updated from the unified-list SSE refresh trigger —
  it is batch-broadcast ~every 500ms per active session and would turn an
  open modal / visible welcome list into a sustained ~1 Hz full projects
  rescan loop; created/deleted (structural changes) are sufficient.
- terminal-ui.js _fetchUnifiedSessions: check the ApiResponse envelope and
  throw on failure so a 5xx surfaces via the caller's catch instead of
  rendering an empty history.
- terminal-ui.js _openSessionRowMenu: on re-entry, invoke the previous
  menu's close fn (stored as _openRowMenuClose) so its document/window
  listeners are detached rather than leaked; use claudeSessionId ||
  sessionId in the 'Resume session' menu item to match the main-row and
  Session Manager resume routing.

Merged — thank you @aakhter! This ties the whole session-management story together: unified welcome list with LIVE/mode badges, per-row kebab menu, and SSE-driven live refresh so the list stays current without manual reload. Because it arrived stacked on the earlier #139/#146 work that had already merged (with review fixes), we rebuilt it onto the current master rather than merging over it — kept your new pieces (the projectKey plumbing for 'View all in this folder', the SSE live-refresh listeners, the kebab menu and badges, the unified welcome list) while preserving master's Command Palette + fixed Session Manager (the naive merge would have re-introduced a stale duplicate that regressed the envelope error-handling and resume routing). The header button is now phone-hidden to satisfy the mobile-header policy guard. Really appreciate how much you moved Codeman forward this cycle — nine merged PRs! 🙏
