| `tools/mutation-table.sh` | One verify job that runs a list of hand mutants (file, before, after, test) against a revision and returns a kill table: CAUGHT with the killing test, SURVIVED, UNVIABLE, TIMEOUT, NOAPPLY, ERROR. Refuses a red or zero-test baseline and a red BUILD; rows print live. Isolation is Docker's: the baselines run once in a container that holds the revision, that container is committed to a throwaway image, and every mutant runs in a fresh `--rm` container from it, so nothing a run writes (tracked, untracked or ignored, such as `target/`) reaches the next mutant; the image is removed when the job ends, killed or not. The shared registry and sccache volumes and the network are not isolated. A file-level load failure (vitest `FAIL <file> [ <file> ]`, jest `FAIL <file>` plus `Test suite failed to run`) reads UNVIABLE. Replaces per-agent runmut/mutrun/strykrun scripts. | Soul, Hands (scoped run) | `references/briefs.md` (Hands verification, Soul reruns) |
| `tools/testparse.sh` | Sourced library: failing test names and pass/fail/skip counts from cargo, dotnet, vitest, jest and pytest logs, and test files that failed to load (`LOADFAIL`). Shared by the summary and the kill table. | the two scripts above | not named by a brief; it lives and dies with them |
| `tools/test-tools.sh` | Local fixture check of the parsers and the summary over `tools/fixtures/logs` (real cargo and mutation logs, plus hand-written dotnet, vitest, jest, pytest, exit-0-but-failed and no-verdict logs), and of the mutation runner's host driver and container half under a mock docker.

Carries a cut_spec's `file_changes` anchors from the spec's base to the worktree by `git diff` hunks (the working tree included) and prints one header, a status table (SAME, MOVED, TOUCHED, RENAMED, NEW, GONE, OUT_OF_RANGE, UNRESOLVED) and windows of at most 100 lines numbered in worktree lines, within `--max-lines` (800). Exit 3 when an anchor cannot be carried, 4 when the spec is unreadable (fetched by id through the eureka-state binding, retried once on Unavailable; `--spec-json` takes a saved view). `--since <sha>` re-prints only the windows edited since that commit. Standard library plus git; writes nothing. | Hands, Soul, Imagination | `references/briefs.md` (Imagination map, Hands, Soul), `SKILL.md` (step 1) |

Prompts under 3 words are not queried. Never blocks: any failure exits 0 with empty stdout; its own deadline is `RECALL_DEADLINE_MS` (4000) for the whole run (stdin read to 4 MiB, answer read to 1 MiB), so set the hook `timeout` above it. One attempt, no retry. Standard library only; writes nothing. | the operator's `UserPromptSubmit` hook in `~/.claude/settings.json` | `references/campaign-state.md` (Precedent) |

"""Push what the mind already holds into an agent's context.
Usage: recall.py prompt (a UserPromptSubmit command hook; the hook JSON is on stdin)
Queries the rulings, questions and follow-ups in force, across every root, ranked
by Huginn's embeddings against the prompt, and prints one hook JSON whose
additionalContext lists the nearest. Huginn's ranking is the only judge of
relevance. It never blocks a prompt: every failure, the deadline included, exits 0
with empty stdout. One attempt, no retry. Standard library only.
Env: RECALL_TOP_K (5), RECALL_BUDGET characters (4000, at most 9000), RECALL_DEADLINE_MS
(4000; set the hook's own timeout above it). The deadline bounds the whole run: stdin, the
reply, parsing, the kill and the write; stdin is read to at most 4 MiB, the answer to 1 MiB.
On Windows the clock starts at process creation, so interpreter start-up and imports (about
200 ms) count against the deadline. What stays outside it: the `py` launcher that starts the
interpreter (40 to 130 ms measured) and the creation call itself, which this script cannot see;
elsewhere the clock starts after the imports (interpreter start about 20 ms).
The recalled text is data written by agents: every field is a JSON string with < > and
