tool read ok: # Shakedown pass criteria

Written before any task was run, per the project's own evaluation-design-first rule. The
point of writing it first is that a criterion invented after the numbers are in is a
description of the numbers.

## What is being tested

Whether the agent, run against a real repository, produces work that the harness can hold
to its own standard. Not whether the model is clever: whether the evidence path holds up
over ten consecutive real tasks without being steered.

## The corpus

Ten tasks drawn from this repository's own small chores, spread across the four task
classes the router already classifies. Every one is work somebody would actually ask for,
not a puzzle constructed to be easy.

| # | Class | Task |
| --- | --- | --- |
| 1 | edit | Name the fuzz corpus directory in the error `fuzz/smoke.mjs` prints when a corpus is missing |
| 2 | edit | Give `PatternUnreadableError` a message naming the pattern it could not read |
| 3 | edit | Report the seed count per harness in `fuzz/smoke.mjs` as a total at the end |
| 4 | test-fix | Add a `scrubText` case for a credential name split by a digit |
| 5 | test-fix | Add a `findBacktrackingRisk` case for a quantifier inside a lookbehind |
| 6 | test-fix | Add a `parseLineHits` case for a section with `DA:` lines but no `LF:` |
| 7 | multi-file | Move the four-character floor constant in `scrub.ts` behind a named export and use it in the test |
| 8 | multi-file | Give `corpus-replay.test.ts` and `smoke.mjs` one shared list of harness names |
| 9 | tool-heavy | Find every `.fuzz.cjs` harness with no entry in `fuzz/README.md` and list them |
| 10 | tool-heavy | Report which `src/gates` files have no test file beside them |

## Dimensions recorded per task

Recorded whatever the outcome, from the run's own output and its bundle, never from the
model's narration:

- gate outcomes, per gate, including not-applicable
- attempts the auto-resolve loop took
- whether it escalated, and on what
- diff size: files changed and lines added
- invariant violations: any file-set breach, any placeholder introduced, any secret-scan
  hit, any ratchet rejection
- whether the exported bundle verifies under its own embedded verifier
- claims made, and how many the harness rendered verified

## What counts as failure

The shakedown fails if any of these happens even once:

1. A bundle does not verify under its own embedded verifier.
2. The harness renders a claim verified that is not true of the cited record.
3. A run reports green while a blocking gate failed.
4. A file outside the declared set is changed with no recorded amendment.
5. The ledger chain breaks, or a run continues after a failed ledger write.
6. A credential written into the workspace reaches the ledger unredacted.

## What is not failure

Named in advance so it cannot be reinterpreted later:

- **An escalation is a result.** The agent hitting the attempt cap and escalating with a
  bundle is the designed behaviour. A shakedown where nothing escalates has tested less.
- **A task the model does badly is not a harness failure.** A wrong or empty edit that the
  gates catch and report is the system working.
- **A ratchet rejection is a result**, and a wanted one: it is the numeric floor doing what
  it is for.
- **Not-applicable gates are not passes and are not failures.** The scratch clone is this
  repository, so typecheck and lint apply here and will run.

## How it is run

Against a scratch clone of this repository at the current commit, one clean clone per task,
so no task inherits another's tree. The frontier model, since the local one has already
been measured separately and the question here is the harness rather than the model.

2cc52b86 Refuse backtracking search patterns, and fuzz three untrusted boundaries
commit 2cc52b86141f6d730cec499fb70105d0f1e9b50b
Author: moonrunnerkc <bradkinnard@proton.me>
Date:   Mon Aug 17 09:36:52 2026 -0600

    Refuse backtracking search patterns, and fuzz three untrusted boundaries
    
    CROSSFIRE's first run against this tree, squashed from crossfire-fuzz-02.
    The three empty round commits are dropped; that branch is kept rather than
    deleted, so the ledger's git_sha references stay reachable.
    
    A search pattern is model output and runs on the main thread once per line,
    where a match in flight cannot be interrupted. src/tools/regex-safety.ts
    reads the pattern structurally and refuses the ambiguous shapes before
    running it, rather than trying to time out a match already underway: a
    variable quantifier inside another, a repeated body that also matches
    nothing, and two variable quantifiers competing for the same characters,
    whether side by side, as alternatives under one quantifier, or split across
    an unquantified capture group, so (a+)(a+)$ is refused the same as a+a+$.
    Parentheses there are a capture, not a boundary. This is known-shape
    refusal, not a proof of linear time, and it is conservative in both
    directions. The gap it does have is a backreference, whose ambiguity exists
    only at match time and so cannot be read off the structure; search-tool.ts
    caps a scanned line at 8000 characters, which bounds that one and the
    quadratic case a long minified line carries for any accepted pattern.
    
    Three Jazzer.js harnesses cover the boundaries model output crosses: the
    ledger write path, the tool chokepoint, and the swarm.toml reader. Each
    loads from .swarm/fuzz-build rather than from src, because a harness that
    imports TypeScript directly runs uninstrumented and reports clean on a
    codebase that is not. fuzz/smoke.mjs replays every harness against its
    seeds, so a stale or broken harness fails the build instead of reporting a
    clean run, and it fuzzes a copy of the corpus so the seeds stay clean.
    
    @jazzer.js/core: coverage-guided fuzzing for the three harnesses, dev-only.

docs/build-guide.md:77: v12 solved a strictly harder version of the section 3.6 problem and the findings were expensive. All of it is readable without restoring anything, from the v12-final tag rather than a branch, because v13 replaces the default branch: git show v12-final:\<path\>. Three inputs and a fixture source: (1) src/audit/cheat-detector/coverage-erosion.ts and assertion-strip.ts hold the numeric monotonicity checks section 3.6 requires, already tuned against false positives on legitimate feature PRs. (2) src/audit/cheat-detector/no-op-fix.ts, no-op-fix-helpers.ts, and src/audit/execution-grounded/no-op-fix-restoration.ts encode a distinction v13's diff-budget and slop checks need: a change is not provably a no-op unless the affected tests execute every reverted changed line, and untested is not the same as cheating (that distinction resolved three false positives on real PRs). (3) The re-specification refuter is the section 3.6 escape hatch. (4) benchmarks/falsification-corpus/v10-synthetic-corpus/ holds roughly 1059 synthetic broken diffs across coverage-erosion, assertion-strip, and related patterns, directly reusable as fixtures the gates must reject.
