Archive detection treated a cached session as archived whenever its ID was absent from the set of JSONL filename stems. A JSONL can hold several session IDs, and its stem need not equal any of them (e.g. after a rename), so live sessions whose source file still existed were reported as archived.

Add CacheManager.get_existing_session_ids, which augments the stem-derived set with every cached session whose recorded source file is still present on disk (scoped per project). Use it in archive counting, HTML-generation planning, and the TUI session browser. Sessions whose sources are genuinely deleted remain archived.

Read-only; does not reconstruct transcripts. Adds focused tests covering renamed sources, multiple sessions per file, deleted sources, a surviving duplicate, cross-project isolation, hidden sessions, the uncached-stem fallback, and a directory sharing a recorded path.

Summary by CodeRabbit

  • Bug Fixes
    • Improved archived-session detection when session IDs differ from JSONL filenames or multiple sessions are stored in one file.
    • Sessions with surviving source files in the same project are no longer incorrectly marked as archived.
    • Deleted sources and files in other projects do not count as active sources.
    • Session loading, archiving, and deletion now correctly handle renamed and shared source files.
    • Confirmation dialogs warn when deleting a source file may affect other sessions.

Merge Risk: ⚪ Minimal · up to 360f4

Archiving a project's last source file now moves its cached sessions to the archived list, so the browser offers Restore. No remaining merge-blocking risk was found.

sessions represented only by agent sources, requiring a surviving trunk source
before adding a session to the current set. Add a regression case in the
relevant test covering a deleted trunk JSONL with a surviving agent JSONL.

Review comments at @claude_code_log/tui.py:
- Around line 1400-1402: Update the archive and delete actions to resolve the
JSONL source path from the cache instead of constructing it from
selected_session_id and project_path. When that path is shared by multiple
session IDs, prevent deletion unless the user explicitly confirms that the
shared file and its other sessions will also be affected.

…tions

Two follow-ups from the CodeRabbit review of this PR:

1. get_existing_session_ids counted any surviving source file, so a deleted
   trunk JSONL whose agent sub-transcript (subagents/agent-*.jsonl) still
   existed kept its session "current" even though trunk discovery cannot load
   it. Restrict resolution to trunk (non-sidechain) rows. Agent files carry the
   trunk session id but are all is_sidechain=1, so a surviving agent file no
   longer rescues a gone trunk.

2. The session browser's Archive and Delete actions built the JSONL path from
   the session id (project_path / f"{session_id}.jsonl"), so for a renamed or
   multi-session file Archive failed and Delete reported success without
   removing the source. Resolve the real trunk source path(s) from the cache
   (get_session_source_paths), falling back to the canonical name only when the
   cache knows no source. When the resolved file is shared with other current
   sessions (get_sessions_sharing_file), the confirm modals now warn that the
   action affects them too, so removal is an explicit choice.

Tests: deleted-trunk/surviving-agent stays archived; trunk+agent stays current;
source-path resolution is trunk-only and drops deleted files; shared-file
lookup excludes hidden and agent rows. Full cache and TUI suites pass.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Classify cached sessions when no JSONL files remain.

If a project has one source JSONL, archiving that file makes valid_session_ids empty. This condition then skips archived-session classification and keeps the cached session in self.sessions. The browser shows the session as current and does not offer Restore. Classify cached sessions against the empty set after the last source file is removed.

Review comment at @claude_code_log/tui.py at line 1453:
Update the cached-session classification flow around valid_session_ids so it
also runs when the set is empty after all source JSONL files are archived.
Ensure cached sessions absent from that empty set are moved to the
archived-session state, allowing the browser to offer Restore instead of
treating them as current.

Follow-up to the CodeRabbit re-review. load_sessions only computed archived
sessions when valid_session_ids was non-empty; archiving the last source JSONL
in a project made the set empty, so the else branch left the orphaned cached
session in self.sessions and showed it as current with no Restore offered.

Always classify against the resolved valid set. When it is empty, every
non-hidden cached session is archived (get_archived_sessions) and self.sessions
is filtered to nothing, so the browser offers Restore instead of pretending the
source still exists. The old "treat all as current" branch for empty sets was a
test-environment shortcut no current test relies on (the TUI fixtures write
<session-id>.jsonl, and the cache-only paths go through is_archived_project or
the run_session_browser entry guard).

Test: load_sessions with a cached session and no JSONL files now lands it in
archived_sessions, not sessions. Full TUI and archive suites pass.
