fix(orchestrator): version-drift + path-hashing leading-dash strip in mcp/server.ts

[evannadeau]

Summary

Two trivial bug fixes in plugins/orchestrator/mcp/server.ts, plus rebuilt dist/server.js. Independent fixes, bundled because they touch the same file and have minimal blast radius.

Fix 1 — Version-drift (mcp/server.ts:655)

system_status reports a hardcoded 0.30.28 instead of the dynamically-read ${PLUGIN_VERSION}. The 0.30.31 consolidation that introduced PLUGIN_VERSION (read from package.json at module load, lines 32-37) explicitly aimed to fix this kind of drift — "the version isn't hardcoded in multiple spots and forgotten on every other version bump" per the comment — but missed this one site. Every release since (0.30.32 → 0.30.38) has shipped system_status returning 0.30.28 while the manifest, package.json, and startup banner all correctly show the current version.

Before:

lines.push(`- **Version**: orchestrator MCP server **0.30.28** (pid ${process.pid})`);

After:

lines.push(`- **Version**: orchestrator MCP server **${PLUGIN_VERSION}** (pid ${process.pid})`);

Cosmetic to user-visible, but operators reading system_status to confirm they're on the expected version are currently misled.

Fix 2 — Path-hashing leading-dash strip (mcp/server.ts:2184)

projectHash strips leading dashes after replacing path separators:

const projectHash = projectDir.replace(/[\\/:]/g, "-").replace(/^-+/, "");

On POSIX, every absolute path produces a leading dash after the replace(/[\\/:]/g, "-") (e.g., /home/user/project → -home-user-project). The subsequent .replace(/^-+/, "") strips it, yielding home-user-project. But Claude Code preserves the leading dash when it names project directories: the actual directory created at ~/.claude/projects/ is -home-user-project, with the dash.

The runtime consequence: projectsHashDir resolves to a non-existent directory. listJsonlFiles() reads readdirSync(projectsHashDir) and the existsSync() guard returns false, yielding []. The agent-channel filewatcher processes zero JSONL files, never writes offsets, never parses @SA-<id8> channel addresses, and never emits routing notifications. Every multi-paragraph PA→SA dispatch on POSIX silently drops until an operator notices and symlinks the stripped path to the real one as a workaround.

Other agent-channel paths (stateDir = join(projectDir, ".orchestrator-state") for sessions.json, system_events DB, etc.) are correctly relative to cwd — only projectsHashDir, which has to match CC's directory naming, is affected.

Before:

const projectHash = projectDir.replace(/[\\/:]/g, "-").replace(/^-+/, "");

After:

// Hash the project directory the same way Claude Code does: replace path separators
// and colons with dashes, preserving any leading dash (POSIX absolute paths produce
// a leading "-home-..." form, and CC keeps the leading dash in ~/.claude/projects/).
const projectHash = projectDir.replace(/[\\/:]/g, "-");

The original strip was over-correction for the Windows drive-letter case (C:\foo → C--foo) — a cosmetic double-dash, not broken routing. Removing the strip is harmless on Windows; on POSIX it's load-bearing.

Diagnostic recipe for anyone reproducing the bug:

1. ls <project>/.orchestrator-state/agent-channel/ — absence of offsets-<id8>.json files means JSONL is not being processed.
2. grep -c '<channel source' <project_jsonl_dir>/<sa_session_id>.jsonl — zero means no events were ever delivered to that SA.
3. Compare paths: actual ls ~/.claude/projects/ shows -home-... with leading dash; plugin-computed projectsHashDir (instrumented via process.env.DEBUG=1 or similar) shows home-... without it.

Test plan

• bun install (98 packages, clean).
• bun run build against the updated source → dist/server.js 0.94 MB, 249 modules bundled. Output regenerated to match source (no stale dist).
• bun test516 pass / 0 fail / 1207 expect() calls across 38 test files.
• Verified PLUGIN_VERSION resolves correctly at module load (already in use at server.ts:464 for version: PLUGIN_VERSION in the MCP serverInfo and at server.ts:2900 for the startup banner — same identifier).
• Re-read both diffs against cb40771 (current main) — line numbers verified directly against main source, not against stale notes.
• Reviewer may want to add an explicit unit test for projectHash against POSIX vs Windows inputs — happy to follow up if requested.

Files changed

• plugins/orchestrator/mcp/server.ts — 2 surgical edits (1 line for version, 1 line + 3 comment lines for path-hashing)
• plugins/orchestrator/dist/server.js — regenerated via bun run build (only 4 lines changed, bundler-deterministic)

Out of scope

Two larger upstream candidates still queued from the same operator's KB:

• Agent-channel filewatcher silently truncating PA-to-SA multi-paragraph assistant_text events at the first colon-after-blank-line — substantive change to the truncation logic, separate PR.
• Concurrent stop-hook deadlock between parallel Claude Code sessions against the orchestrator SQLite DB — architectural fix, separate PR.

Both will ship after maintainer review of the trivial-fix bundle here.
