2026-10-13-grok-build-the-1-0-52-guide-corrects-imported-hook-compatibility-and-documents-fail-open-traps

The 1.0.52 guide corrects imported-hook compatibility and documents fail-open traps. The stable guide changes the compatibility promise, rather than proving a newly introduced SessionStart regression or historical ineffective Cursor execution. It now explicitly names new/load and rejects native Cursor reply compatibility. The package-root path trap is documented at 1.0.52; its first affected version is unknown. General fail-open behavior has specific exceptions for oversized gate replies and invalid input rewrites.

Channel: tagged-release (shipped 1.0.50/1.0.52 guides and versioned notes). Half: both. Date: 2026-10-11 (1.0.52 documentation; selected notes from 2026-09-26 and 2026-10-09).

Operator consequence: Re-test migrated hooks on 1.0.52: translate SessionStart matchers, convert Cursor entries to Grok-supported matcher groups and point package hooks at scripts that exist. Review package/subfolder hook sources. Make reachable script error paths return explicit deny, while recognizing that a missing script or failed request cannot return one. Do not use a fallible hook as the only boundary.
