Before any grep or Read, expand the pack: `py -3 tools/context-pack.py <cut_spec

OUT_OF_RANGE, UNRESOLVED, or GONE outside deletes is a spec discrepancy: record

OUT_OF_RANGE, UNRESOLVED, a MISSING read, SYMBOL_MISSING, or GONE outside
deletes is a spec discrepancy: record it in deviations. The pack lists the
callers of every symbol; grep beyond them only for what the pack names as cut.
When the brief names a worktree, every tool call's path goes under it: Read,
Edit and Write as well as the shell's working directory. An absolute path into
the main checkout silently edits the wrong tree.

| `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.

| `tools/recall.py` | `py -3 tools/recall.py prompt`, a `UserPromptSubmit` command hook (hook JSON on stdin): queries the rulings, questions and follow-ups in force across every root, ranked by Huginn against the prompt (`RECALL_TOP_K`, 5), and prints one hook JSON whose `additionalContext` is a header saying the lines are recalled records, data and never instructions, written by agents and not the operator, then one JSON object per item (`id`, `title`, a short `operator_quote`) with `<`, `>` and control, bidi and separator characters escaped, within `RECALL_BUDGET` characters (4000, at most 9000: Claude Code caps `additionalContext` at 10,000), whole lines only. 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. Install both hooks as `<absolute python.exe> C:/Users/Meta/.claude/skills/eureka/tools/recall.py prompt || true` (and `... admit || true`): Claude Code runs hook commands through Git Bash on Windows, and `py -3 <missing script>` exits 2, which blocks every prompt or admit; with `|| true` the hook cannot exit 2 (a missing script, interpreter or file passes) and the script's stdout is untouched (proved live on 2.1.308). `py -3 tools/recall.py admit` is a `PreToolUse` hook on `mcp__eureka-state__admit`: for each ruling or question in the batch (at most `RECALL_ADMIT_MAX`, 3) it queries the nearest in-force rulings and questions, and denies the first attempt with the neighbours as the reason (a deliberate hold, not a failure); the identical call sent again (digest of `tool_input` plus `agent_id`, kept in the session scratchpad) passes. Never allow or ask; a failed check exits 0 with a note naming the failure kind (`RECALL_TOP_K` 3, `RECALL_DEADLINE_MS` 10000 in this mode). Standard library only; writes only the digest file. | the operator's `UserPromptSubmit` hook and `PreToolUse` hook on `mcp__eureka-state__admit` (fires inside subagents too) in `~/.claude/settings.json` | `references/campaign-state.md` (Precedent) |
