Subject: [PATCH 01/10] fix(debug): create log dir before appendFileSync to
 prevent ENOENT

appendFileSync fails when ~/.deeplake/ does not exist (e.g. tests that
set a temp HOME). Add mkdirSync with recursive:true so the dir is
created on first debug write, making the logger self-contained.

Subject: [PATCH 02/10] fix(pre-tool-use): route unroutable VFS commands to
 deeplake-shell
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commands that pass isSafe() but have no inline handler (echo redirects,
jq pipes, find with unsupported flags) previously returned RETRY REQUIRED.
They now fall through to the VFS shell bundle which handles them in a
sandboxed Node.js interpreter against the SQL backend — no host
filesystem access occurs.

Fixes: echo/printf writes, pipe chains, and non-standard find patterns
all working end-to-end against the Deeplake SQL memory table.

Subject: [PATCH 03/10] fix(#94): respect claude plugin disable in running
 sessions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hooks are loaded at SessionStart and stay active for the session lifetime
even after `claude plugin disable hivemind`. Each capture and session-end
invocation now reads enabledPlugins from ~/.claude/settings.json at runtime
and exits early if the plugin is disabled — no capture, no wiki worker.

Fails open: a missing or corrupt settings.json is treated as enabled so
a bad file does not silently drop all captures.

Subject: [PATCH 04/10] fix(agents): VFS write routing + plugin-disable for
 Codex/Cursor/Hermes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

VFS write (pre-tool-use):
- Codex: unroutable isSafe commands now run via spawnSync against the VFS
  shell bundle and return {action:"block", output} — prevents host shell
  access while delivering the write/pipe result to the agent. Falls back
  to guidance if the shell exits non-zero (e.g. bundle missing in tests).

Plugin disable (#94):
- Codex/Cursor/Hermes capture hooks now read ~/.claude/settings.json at
  runtime and exit early when enabledPlugins[hivemind@hivemind]=false,
  matching the Claude Code fix from the previous commit.

Verified: 4241 unit tests pass; end-to-end plugin-disable confirmed via
log output on all four agents.

Subject: [PATCH 05/10] fix(install): link embed-deps node_modules for
 Codex/Cursor/Hermes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

graph-on-stop.js uses tree-sitter as an external native module — esbuild
cannot bundle it. The plugin dir's node_modules must resolve to
~/.hivemind/embed-deps/node_modules (which contains tree-sitter after
hivemind embeddings install).

installCodex/Cursor/Hermes now replace any empty placeholder dir at
<pluginDir>/node_modules with a symlink to embed-deps, matching what
ensurePluginNodeModulesLink does at runtime for Claude Code. Without
this, graph-on-stop exits 1 with ERR_MODULE_NOT_FOUND on every Codex/
Cursor/Hermes session end.

Subject: [PATCH 06/10] fix(codex): use guide action for successful VFS writes
 so Codex reports success
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the VFS shell executes a write redirect (echo/printf/tee … > file)
and exits 0, return action="guide" instead of "block". "block" exits 2
which makes Codex report "command blocked" even when the SQL write
succeeded — confusing the agent. "guide" exits 0 so Codex treats the
command as successful and shows the output to the agent.

Non-redirect commands (pipes, finds, reads that fall through) still use
"block" to prevent unsafe host-shell execution.

 wiki-worker lock check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

forceSessionEndTrigger was placed after the wiki-worker tryAcquireLock
check. When the Periodic trigger from capture.ts had already acquired
that lock, session-end.ts returned early and the skillify worker was
never spawned — skills were never generated for authenticated users.

Move forceSessionEndTrigger before the wiki-worker lock check: the
skillify trigger has its own per-project lock so it does not need the
wiki-worker to be free. Also fall back to process.cwd() when input.cwd
is absent so the project key can always be derived.

Subject: [PATCH 09/10] fix(session-end): fire skillify before wiki-worker lock
 in Cursor/Hermes/Codex

Same bug as Claude Code (fixed in b63105ae): forceSessionEndTrigger was
placed after the wiki-worker tryAcquireLock check in all three agents.
When the Periodic trigger already held the lock, session-end returned
early and skill mining was silently skipped.

Move forceSessionEndTrigger before the lock check in cursor/session-end,
hermes/session-end, and codex/stop. Also add process.cwd() fallback for
Codex which used `input.cwd ?? ""`.

Add lock-contention regression tests to all four agents asserting that
forceSessionEndTrigger fires even when tryAcquireLock returns false.

Subject: [PATCH 10/10] test(install-cursor): cover embed-deps symlink branches
 to meet 80% threshold
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three new cases for the lstatSync/symlinkForce block in installCursor:
- embed-deps exists, pluginNm absent (lstatSync throws → catch, then symlink)
- embed-deps exists, pluginNm is a real directory (rmSync + symlink)
- embed-deps absent (skip the block entirely)

Raises branch coverage from 76% to ≥80% to clear the CI threshold.
