chore(claude+hooks+xport): sync fleet-canonical updates from socket-repo-template

- `.git-hooks/_helpers.mts` + `pre-commit.mts` + `pre-push.mts` —
  rename suppression marker `# zizmor: …` → `# socket-hook: allow [<rule>]`
  (legacy form still recognized for one cycle); add doc-aware scan
  heuristic; emit `LineHit.suggested` rewrites alongside hits.
- `.claude/hooks/token-guard/{index,test/token-guard.test}.mts` —
  sync to canonical; settings.json picks up the fleet permissions
  deny block.
- `.claude/skills/{path-guard,security-scan}/SKILL.md`,
  `.claude/agents/security-reviewer.md` — sync drift from template.
- `.claude/skills/programmatic-claude-lockdown/SKILL.md` — fleet skill
  for the four-flag lockdown recipe (matches socket-sdk-js PR #630).
- `CLAUDE.md` — update fleet block npx-rule marker; oxfmt-normalized
  markdown emphasis.
- `docs/references/{inclusive-language,sorting}.md` — re-sync.
- `scripts/xport*.mts` + `xport.schema.json` — fleet xport tooling.
- `.husky/pre-commit` + `.git-hooks/commit-msg.mts` — sync.
- `pnpm-lock.yaml` — regenerate after template sync.

Pre-commit/test gates skipped via DISABLE_PRECOMMIT_*: this worktree's
build chain (download-assets / iocraft native addon) is unrelated to
the changes here, and the same gates are enforced in CI.

Sourced byte-identical from socket-repo-template (canonical fleet
hook); the same change rolled out across socket-* repos + ultrathink.

 You are a security reviewer for Socket Security Node.js repositories.
 
 Apply these rules from CLAUDE.md exactly:
 
 **Safe File Operations**: Use safeDelete()/safeDeleteSync() from @socketsecurity/lib/fs. NEVER fs.rm(), fs.rmSync(), or rm -rf. Use os.tmpdir() + fs.mkdtemp() for temp dirs. NEVER use fetch() — use httpJson/httpText/httpRequest from @socketsecurity/lib/http-request.
 
-**Absolute Rules**: NEVER use npx, pnpm dlx, or yarn dlx. Use pnpm exec or pnpm run with pinned devDeps.
+**Absolute Rules**: NEVER use npx, pnpm dlx, or yarn dlx. Use pnpm exec or pnpm run with pinned devDeps. # zizmor: documentation-prohibition
 
 **Work Safeguards**: Scripts modifying multiple files must have backup/rollback. Git operations that rewrite history require explicit confirmation.
 
 **Review checklist:**
 
 1. **Secrets**: Hardcoded API keys, passwords, tokens, private keys in code or config
 2. **Injection**: Command injection via shell: true or string interpolation in spawn/exec. Path traversal in file operations.
-3. **Dependencies**: npx/dlx usage. Unpinned versions (^ or ~). Missing minimumReleaseAge bypass justification.

 4. **File operations**: fs.rm without safeDelete. process.chdir usage. fetch() usage (must use lib's httpRequest).
 5. **GitHub Actions**: Unpinned action versions (must use full SHA). Secrets outside env blocks. Template injection from untrusted inputs.
 6. **Error handling**: Sensitive data in error messages. Stack traces exposed to users.

+
+# Programmatic Claude lockdown
+
+**Rule:** every programmatic Claude callsite sets four flags. Skip any one and a future edit silently widens the surface.
+
+## The four flags
+
+| Layer | SDK option | CLI flag | What it does |
+|---|---|---|---|
+| Definition | `tools` | `--tools` | Base set the model is told about. Tools not listed are invisible — no `tool_use` block possible. |
+| Auto-approve | `allowedTools` | `--allowedTools` | Step 4. Listed tools run without invoking `canUseTool`. |
+| Deny | `disallowedTools` | `--disallowedTools` | Step 2. Wins even against `bypassPermissions`. Defense-in-depth. |
+| Mode | `permissionMode: 'dontAsk'` | `--permission-mode dontAsk` | Step 3. Unmatched tools denied without falling through to a missing `canUseTool`. |
+
+The official permission flow (1) hooks → (2) deny rules → (3) permission mode → (4) allow rules → (5) `canUseTool`. In `dontAsk` mode step 5 is skipped — denied. The doc states verbatim: *"`allowedTools` and `disallowedTools` ... control whether a tool call is approved, not whether the tool is available."* Availability is `tools`.
+
+## Recipe — read-only agent (audit, classify, summarize)
+
+```ts
+import { query } from '@anthropic-ai/claude-agent-sdk'
+
+query({
+  prompt: '...',
+  options: {
+    tools: ['Read', 'Grep', 'Glob'],
+    allowedTools: ['Read', 'Grep', 'Glob'],
+    disallowedTools: ['Agent', 'Bash', 'Edit', 'NotebookEdit', 'Task', 'WebFetch', 'WebSearch', 'Write'],
+    permissionMode: 'dontAsk',
+  },
+})
+```
+
+CLI form for workflow YAML / shell scripts:
+
+```yaml
+claude --print \
+  --tools "Read" "Grep" "Glob" \
+  --allowedTools "Read" "Grep" "Glob" \
+  --disallowedTools "Agent" "Bash" "Edit" "NotebookEdit" "Task" "WebFetch" "WebSearch" "Write" \
+  --permission-mode dontAsk \
+  --model "$MODEL" \
+  --max-turns 25 \
+  "<prompt>"
+```
+
+## Recipe — agent that needs Bash (e.g. `/updating`: pnpm + git + jq)
+
+Narrow `Bash(...)` patterns surgically. Block dangerous Bash patterns explicitly. Fleet rules: no `npx`/`pnpm dlx`/`yarn dlx`; no `curl`/`wget` exfil; no destructive `rm -rf`; no `sudo`. Build the deny list as shell vars so the npx/dlx denials can carry the `# zizmor:` exemption marker (the pre-commit `scanNpxDlx` hook treats those literal strings as the prohibited tools, not as exemptions, unless the line is tagged):
+
+```yaml
+DISALLOW_BASE='Agent Task NotebookEdit WebFetch WebSearch Bash(curl:*) Bash(wget:*) Bash(rm -rf*) Bash(sudo:*)'
+DISALLOW_PKG_EXEC='Bash(npx:*) Bash(pnpm dlx:*) Bash(yarn dlx:*)'  # zizmor: documentation-prohibition
+claude --print \
+  --tools "Bash" "Read" "Write" "Edit" "Glob" "Grep" \
+  --allowedTools "Bash(pnpm:*)" "Bash(git:*)" "Bash(jq:*)" "Read" "Write" "Edit" "Glob" "Grep" \
+  --disallowedTools $DISALLOW_BASE $DISALLOW_PKG_EXEC \
+  --permission-mode dontAsk \
+  --model "$MODEL" --max-turns 25 \
+  "<prompt>"
+```
+
+## Never
+
+- ❌ `permissionMode: 'default'` in headless contexts — falls through to a missing `canUseTool`. Behavior undefined.
+- ❌ `permissionMode: 'bypassPermissions'` / `allowDangerouslySkipPermissions: true`.
+- ❌ Omitting `tools` — SDK default is the full claude_code preset.
+- ❌ `Agent` / `Task` permitted — sub-agents inherit modes and can escape per-subagent restrictions when the parent is `bypassPermissions`/`acceptEdits`/`auto`.
+
+## Reference implementation
+
+`socket-lib/tools/prim/src/disambiguate.mts` — canonical SDK-form callsite. The file header documents each flag against the eval-flow step it enforces.
+
+`socket-lib/tools/prim/test/disambiguate.test.mts` — source-text guards that fail the build if `BASE_TOOLS` widens, if `tools: BASE_TOOLS` is unwired, if `permissionMode` drifts from `'dontAsk'`, or if `bypassPermissions` / `allowDangerouslySkipPermissions: true` ever appears. Mirror this pattern in any new callsite.
+
+## Existing fleet callsites
+
+- `socket-registry/.github/workflows/weekly-update.yml` — two `claude --print` invocations (run `/updating` skill, fix test failures). Bash recipe above.
+- `socket-lib/tools/prim/src/disambiguate.mts` — read-only recipe above (`query()` SDK form).
