On NTFS the fixture self-collides: .builtin-manifest auto-generates the
8.3 short name BUILTI~1, so writing that fixture file opens the manifest
through its alias and clobbers it -- the exact threat the guard models.
Gate the fixture-based test to unix, and add a windows counterpart that
proves the collision where 8.3 generation is enabled and asserts the
filter invariant (alias-shaped entries are neither removal candidates
nor claimed) either way.
- one shared exec-bit predicate (Language-recognized extensions => 0755) used by
every hook/agent installer; non-script files in hooks dirs stay non-executable
- mixin discovery scans the global hooks dir and each agent's hooks dir;
.builtin-manifest is never scanned
- NTFS 8.3 short-name aliases rejected as builtin-manifest entries
- hook-script install announcements restricted to real hook locations
- COYOTE_HOOKS_DIR override warning compares canonicalized paths
- embedded assets decode via checked from_utf8 instead of from_utf8_unchecked
- log-events.sh defaults under ${XDG_STATE_HOME:-$HOME/.local/state}/coyote/hooks.log
keeping 0600/symlink-refusal/secret-filter hardening; notify.sh tty fallback strips
control bytes; both use UTC ISO-8601 timestamps
- payload files orphaned by a write failure are unlinked; stale coyote-hook-*.json
payloads swept best-effort at startup
- sweep_removed_agent_hooks never follows symlinked agent dirs
- usage-probe-hooks.sh replaces bare sleeps with a bounded poll, re-verifies 0755 on
restored scripts, and covers roles/agent hook locations
- TestConfigDirGuard hoisted into crate::testing
- .gitattributes pins LF line endings for bundled scripts
hooks is now a reserved bundle name.
Bundles: RemoteLayout.hooks + scan/is_empty/plan routing into hooks_dir,
a functional --filter hooks arm replacing the inert interim arm,
TopCategory::Hooks provenance rows, and per-file 'bundle defines hook
script' summary lines (visibility only, no approval prompt).
Reconciliation: new builtin_manifest module — a hidden per-directory
.builtin-manifest records the files the builtin installer actually owns
(written this run, previously owned, or pending failed deletions);
deletion is strictly manifest-minus-embed so user-created files in the
same directory are never touched. Wired into install_builtin_agents for
agents/<name>/hooks/ and a greenfield minimal Role::install_builtin_role_hooks
for roles/hooks/.
Hardening: bundles are barred from shipping any path component that
aliases .builtin-manifest (Unicode case fold + trailing dot/space,
directories included); manifest entries reuse the bundle store's
is_safe_component rules; malformed manifests fail safe toward keeping
files; role-side reconcile failures degrade to a warning like the
agent side.
