feat(sessions): experimental cross-project search (projects / --project) - #449
Merged

Conversation
codegraph_sessions takes projects (CLI --project), up to five paths. Each project answers from its own session index; hits interleave by each project's own rank and name their project, under one limit and one byte budget. A project without transcripts, with sessions off, or without an index is listed as skipped. The core is src/sessions/fanout.ts, so reverting this commit removes the experiment.

Inline comments:
Review comments at @src/bin/codegraph.ts:
- Around line 1517-1518: Update the project-resolution branch around
resolveProjectPath and isInitialized to detect when the requested path is a
separate nested repository before accepting an indexed ancestor; skip that
request rather than searching the ancestor’s sessions or labels.
Review comments at @src/mcp/tools.ts:
- Around line 4491-4493: In `src/mcp/tools.ts` lines 4491-4493, bound the
supplied paths before validating or resolving them with `getCodeGraph`, and
retain the dropped-project count. In `src/bin/codegraph.ts` lines 1516-1519,
likewise avoid filesystem resolution for paths beyond the bounded target set and
retain the dropped-project count.
- Around line 3114-3115: Update the anchor selection in the projects-only search
branch so it sets projectPath only when a usable indexed anchor or default
project exists; when none exists, leave projectPath unset so awaitProjectGate
does not block handleSessions from reporting all paths as skipped.
- Around line 2074-2077: Update the no-default-project schema handling in
getTools for codegraph_sessions so clients can provide either projectPath or
projects when this.cg is null; do not make projectPath unconditionally required
by withRequiredProjectPath for this tool.
Review comments at @src/sessions/fanout.ts:
- Line 85: Update the fanout flow around querySessions to fetch candidate
passages without applying per-project passage budgets, select the merged hits,
then apply withinPassageBudget once to that merged selection so cut counts
reflect the shared budget.
- Line 138: Update the hit heading in the fanout flow to identify each project
unambiguously when selected projects share a directory name; use the project
root or a unique suffix instead of relying on path.basename(h.project), while
preserving the session and title information.

Included review availability: This review used your included allowance. Your plan provides up to 10 included reviews per hour; 7 remain after this review.
Budget the merged selection once (unbudgeted per-project passages), bound the project list before resolving paths, let a projects-only call run with no default project or no indexed project, and name a project by its root when two share a directory name.

What
codegraph_sessionstakesprojects(CLI:--project <path...>), up to five project paths, and searches their session histories in one call. This is an experiment, built so it can be removed with onegit revert..codegraph/sessions-v2.db; nothing is shared across projects. Hits interleave by each project's own rank (BM25 scores are not comparable across indexes) and name their project. One limit and one 16,000-byte passage budget cover the list."sessions": false, or without an index is listed as skipped and never fails the call.src/sessions/fanout.ts. Existing code changed only at the edges:withinPassageBudgetis exported, the tool schema gainsprojects(and arrayitemsinPropertySchema),executeanchors aprojectscall on the first indexed project, and the CLI gains--project. Withoutprojects, behaviour is unchanged.Choices to check
Checks

Site CLI and MCP pages and the server instructions are updated; CHANGELOG has the entry. No measured number in the README moves.Requirements: the cross-project search draft recommended deferring; the user chose to build it as an undoable experiment.
