fix: preserve base-defense guard fixes on current upstream

[faisfamilytravel]

Summary

• Preserves Base Defense guard fixes on current upstream main.
• Keeps the prepared change on a clean PR branch instead of pushing the live XO checkout.
• Excludes local .bak preservation artifacts from upstream.
• Resolves the upstream overlap in tools/file_tools.py.
• Includes the timing-stability correction for the delegate heartbeat test reproduced during PR-prep validation.
• Adds the local contributor email mapping required by the repository attribution check.
• Adds per-test timeout headroom for the interrupt-cleanup regression test so CI's global 30s timeout does not preempt its own 30s process-group diagnostic wait.

Validation

• Focused gate: 660 passed in 17.31s.
• Secondary focused gate: 670 passed, 4 skipped, 1 warning in 28.31s.
• Repaired delegate heartbeat test rerun: 1 passed, 1 warning in 1.55s.
• python3 -m py_compile scripts/release.py passed after the attribution-map follow-up.
• python -m pytest tests/tools/test_local_interrupt_cleanup.py -q -o 'addopts=' --timeout=60: 2 passed in 0.70s after the CI timeout-headroom follow-up.

Operational notes

• This branch was prepared in an isolated worktree from fresh origin/main.
• The live XO checkout was not switched, merged, rebased, reset, or restarted.
• Original local live checkout remains a separate local/rollback lane.
• Direct push to NousResearch/hermes-agent was denied for faisfamilytravel; PR was opened from fork faisfamilytravel/hermes-agent instead.

Thanks for preserving several potentially useful fixes. This cannot be salvaged as one PR against current main.

Problems

• tools/claude_brain_tools.py:31-39 adds a 611-line built-in tool module with hard-coded /Users/rfais370/... paths. Built-in discovery imports self-registering tool files (tools/registry.py:58-75; model_tools.py:188), and the default tool-definition path resolves registered toolsets (model_tools.py:389-393; toolsets.py:814-836).
• The claimed one-time override is non-functional: _resolve_write_target() rejects out-of-lane writes at tools/claude_brain_tools.py:260-263, never calls _consume_override() (:290-309), and returns override_used=False at :271.
• The Matrix changes target gateway/platforms/matrix.py, but current main moved the adapter to plugins/platforms/matrix/adapter.py (migration commit 560010547). This needs a fresh, focused review rather than a mechanical apply.

Suggested changes

• Drop the Claude-Brain module from this PR; if needed, ship it as a standalone plugin with portable configuration and tests.
• Split and re-verify each remaining fix against current main before salvage.

Automated hermes-sweeper review.

[teknium1]

Blocking: this adds contributor-specific macOS paths to a built-in auto-discovered tool module. Built-in tools must be portable and broadly justified; move this collaboration-lane integration to a standalone plugin instead of shipping /Users/rfais370/... defaults in core.

[teknium1]

Blocking: override_id is never consumed. This return rejects the out-of-lane case before _consume_override() can run, and the successful path always returns override_used=False; the documented one-time override mechanism is therefore unreachable.

[faisfamilytravel]

Superseding this omnibus PR with current-main, single-purpose repairs after the maintainer review:

• fix: make shutdown diagnostics portable without coreutils timeout #64515 — portable shutdown diagnostics without the GNU timeout dependency
• fix: allow only the current macOS user temp root #64517 — narrowly allow only the current macOS user temp root while preserving /private/var and Hermes-config protections

The Claude-Brain capability has been removed from the Hermes-core proposal and retained as an FFT-owned standalone, profile-scoped plugin with portable configuration, fail-closed writes, atomic one-time overrides, preflight checks, and regression coverage.

The Matrix patch is not being carried forward. Current plugins/platforms/matrix/adapter.py already has complete enum fallback stubs and lazy dependency rebinding; mechanically porting the old gateway/platforms/matrix.py wrappers would mask dependency incompatibility rather than fix a reproduced current-main defect.

The remaining provider/model/cron changes were audited individually and were already handled generically, obsolete, mock-only, or not production-reproducible on current main.

Closing #37320 as superseded rather than rebasing the mixed change set.
