The (condition, action) spec is stored privately under `state/when/` and hash-bound by a trust record the same way `bin/fm-check-register.sh` binds a custom check, while the spec separately binds the resolved action executable's bytes; a mutated or unregistered spec or a changed action executable is refused before the action runs. An action that needs environment to work at all is armed with hash-bound `NAME=VALUE` assignments recorded in that same spec, and the action executable stays argv[0], so binding its bytes is unaffected. diff --git a/docs/scripts.md b/docs/scripts.md index e7e8d87423d..d170ec6f3be 100644 --- a/docs/scripts.md +++ b/docs/scripts.md @@ -83,6 +83,7 @@ The shared no-mistakes gate refusal for fleet lifecycle entrypoints is summarize | `fm-extension.sh` | Expose extension binding commands through the tracked shell and remote-home command boundary | | `fm-procevent.sh` | Register, supervise, capture, classify, acknowledge, and safely retire built-in or explicitly bound process-event sources | | `fm-procevent-remote-reply.sh` | Relay the remote-secondmate status stream through non-destructive process-event deltas | +| `fm-procevent-markfeed.sh` | Wake Firstmate when a page mark feed's poll command prints owner marks, or stop safely when it fails | | `fm-procevent-quota.sh` | Wake Firstmate when tracked quota drops below a threshold, is exhausted, or cannot be polled | | `fm-procevent-when.sh` | Fire a trust-bound deterministic action when its registered condition holds - once, or on every change under `--repeat` - then wake with the outcome | | `fm-gate-refuse-lib.sh` | Shared no-mistakes gate-context refusal for fleet lifecycle entrypoints | diff --git a/tests/fm-procevent-markfeed.test.sh b/tests/fm-procevent-markfeed.test.sh new file mode 100755 index 00000000000..54b4dac7e46 --- /dev/null +++ b/tests/fm-procevent-markfeed.test.sh @@ -0,0 +1,118 @@ +#!/usr/bin/env bash +# Behavioral tests for bin/fm-procevent-markfeed.sh. +set -u + +SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)" +FM_ROOT="${FM_ROOT_OVERRIDE:-$(cd "$SCRIPT_DIR/.." && pwd)}" +BIN="$FM_ROOT/bin" +LAB=$(mktemp -d "${TMPDIR:-/tmp}/fm-procevent-markfeed.XXXXXX") + +cleanup() { rm -rf "$LAB";
