Review blockers (independent reviewer on #94513): 1. Reinstalling an exclude-mode catalog entry wiped the user's edited tools.exclude, replacing it with manifest defaults. install_entry now reads the prior exclude (like it already did for include) and re-writes it verbatim on reinstall. Regression test added + sabotage-verified (fails on old behavior); include-priority test added too. 2. aws-knowledge: exclude aws___retrieve_skill — vendor SKILL.md loader is a vendor skill layer (live tools/list confirmed the tool exists). 3. betterstack: exclude list rewritten to cover the snake_case wire names (vendor's own header examples show remove_dashboard) via globs alongside the doc display-labels; caveat documented in the manifest — server is OAuth-gated so pre-auth enumeration is impossible. 4. railway: exclude railway-agent (opaque server-side agent delegation, acts outside Hermes's per-tool approval loop). 5. twelve-data: exclude oauth plumbing pseudo-tools + quota probe. 6. betterstack post_install no longer claims a fully-checked checklist — exclude-mode bypasses the checklist; text now describes the applied exclude list. Live E2E: fresh temp HERMES_HOME — install applies manifest excludes, user edit survives reinstall. 33/33 catalog tests green.
