step 32: calling local:qwen3.6:35b-mlx
claim (unverified): The task is complete. Here's a summary:

**Change made:** Modified `fuzz/smoke.mjs` to assert that every `.fuzz.cjs` harness has a non-empty corpus directory beside it.

**What was added:** After the try/catch block that reads the corpus directory for each harness, I inserted an explicit check:
```js
if (seeds.length === 0) {
    console.error(`fuzz/smoke: ${harness.name} has an empty corpus at ${corpus}`);
    failures += 1;
    continue;
}
```

This ensures that a harness with an empty (or missing) corpus directory will be flagged as a failure, rather than silently passing with zero seeds run. Previously, a completely absent or empty corpus directory would result in `seeds` being undefined/empty and the test continuing without running any seeds — no longer caught.

Swarm Orchestrator v13: an evidence-first coding agent. Every claim of completed work must resolve to machine-captured evidence in a tamper-evident ledger. Quality gates run and auto-resolve under a ratchet. Local model selection is measured, never guessed. Full rationale lives in docs/build-guide.md; read it before structural work.

## Commands

- `npm run typecheck` : tsc, strict, no emit
- `npm run lint` : Biome check
- `npm run format` : Biome format, write
- `npm test` : Vitest, full suite
- `npm run gates` : all of the above in sequence; this is the definition of green
- `npm run dev` : run the CLI from source against a scratch workspace

Run `npm run gates` before claiming any task complete. Paste the real output. Never summarize gate results from memory.

## Architecture Map

- `src/agent-run.ts` : one task start to finish (sandbox, tools, chokepoint, loop, gates). The CLI and every parallel worker call this same function; a worker differs only in its directory and its chain.
- `src/core` : agent loop. Plan, act, verify. All stochastic inputs (clock, random, model) injected via interfaces, never imported directly.
- `src/tools` : read, write, edit, shell, search, list. Every call goes through the chokepoint in `src/tools/chokepoint.ts`: ledger record, provenance tag, sandbox enforcement. No tool may bypass it.
- `src/evidence` : append-only JSONL ledger, hash chain, content-addressed blob store, evidence DAG, bundle export, embedded verifier, HTML review renderer.
- `src/gates` : gate definitions as data, runner, auto-resolve loop with ratchet, escalation.
- `src/providers` : the only module allowed to import the Vercel AI SDK. Frontier plus OpenAI-compatible local (Ollama, rapid-mlx). Local endpoint discovery.
- `src/select` : hardware probe, static shortlist fit, calibration micro-eval, bandit reward log.
- `src/workers` : phase 6 scale-out. Git worktree per worker, each running the ordinary loop from `src/agent-run.ts`, and a merge queue that lands them sequentially under the ratchet. Nothing here is imported by the single-agent path.
- `src/tui` : Ink single-screen UI. Renders exclusively from ledger projections.
- `src/config` : Zod-validated swarm.toml, zero-config defaults.

## Invariants (violating any of these fails review)

1. Model output is a claim. Harness-captured output is evidence. A claim is a structured assertion: a machine-checkable predicate against a named record, together with the kind of record it asserts against, evaluated by the harness, which computes the verdict. The harness recomputes the cited record's kind and rejects a claim whose declared kind does not match, as UNVERIFIED with the sub-reason predicate-kind-mismatch. A payload digest has to name one record for that to mean anything: identical content is one blob by design, so the resolution keeps every record a digest is carried under, and a digest carried under more than one kind names none of them and backs no claim, honest or otherwise. Which record a claim cites is decided once, by the harness, when the claim is submitted, and recorded with the claim: a record appended afterwards cannot reach back and strip verified status off earlier work by reusing its digest under another kind, and a digest that already named more than one kind when the claim was made binds to nothing, so that claim renders UNVERIFIED with the collision named. That check is load-bearing because one record type covers many subjects: every gate writes a gate-run and every tool writes a tool-call, so a predicate that holds against the lint run is not evidence about the tests gate, and a lifecycle record can never satisfy a gate-outcome claim. Free-text narrative always renders as unverified prose and can never render green. Missing records, kind mismatches, and unparseable predicates render UNVERIFIED; they never abort the run. UI status, gate results, and bundle verdicts derive only from harness-evaluated predicates over ledger records, never from model text.
2. The ledger is append-only. No update, no delete, no rewrite. Each record carries the previous record's hash. A failed ledger write aborts execution.
3. Every tool call passes through the chokepoint. Adding a tool means adding a definition, not a new execution path. The sandbox default-denies reads of credential paths (.env*, *.pem, *.key, .git/config, ~/.aws, ~/.ssh), and every denial is recorded as evidence.
4. Blob store is content-addressed by SHA-256. Same content, same key, no exceptions.
5. Every value entering a tool call carries a provenance tag: user, model, tool-output, or file. Derivation detection is heuristic: tool-call arguments matching untrusted content read within a recent window (substring or normalized n-gram overlap, window and threshold configurable) route through the confirmation path. Treat it as a tunable heuristic with a false-positive rate, never describe it as an information-flow guarantee.
6. Gate results are data. Gate definitions declare command, output parser, and blocking or advisory. Engine logic never special-cases a gate.
7. The ratchet is numeric. During auto-resolve: tests collected non-decreasing; assertions in touched test files non-decreasing; coverage of changed lines non-decreasing; skip markers non-increasing; no previously passing gate regresses. Coverage of changed lines comes from a report the runner wrote to a path the harness named, outside the workspace, and never from what a gate printed: a number the code under measurement can author is not a measurement of it, and no artifact means not measured. Only a complete lcov report is a report: every section opened by `SF:`, carrying at least one `DA:` line, closed by `end_of_record`, and declaring `LF:`/`LH:` totals that agree with the lines beside them. A truncated, header-only, or otherwise malformed artifact renders not measured, exactly as an absent one does, and there is no second format to fall back to. The artifact is only worth reading while the tests are somewhere else, so the harness forces process isolation for its coverage cycle: under a shared process the destination sits in the test's own argv and the subject writes its own measurement. Where isolation cannot be forced, no report is asked for and the arm is not measured. A retry violating any of these is rejected and the attempt still counts. The same comparison runs once more at the end, between the final state and the base commit, whether or not any retry happened: without it a run whose first edit deleted the failing tests reaches a green first cycle and is never compared to anything, and a rejection there escalates instead of reporting green. One exception, granted per test and never per file: a test that is new in the submitted file, failed on the base source, and passes on the submitted source is a new specification, not tampering, and pays for exactly one deleted test in that file. Which tests failed on the base source is read from the runner's own machine-readable result, written to a path the harness named, never from the reporter output a person reads: a fail marker a test printed for the test beside it is not a test that failed. A file-level exemption would drop the file from the comparison and carry every deletion beside it, and a base-source failure that is a load error proves nothing, since a file that never executed did not fail as a specification. A symbol the base does not export is that failure whichever module system reports it: a SyntaxError from an import, or a TypeError at the first call through a require. A measure nothing measured is abstained on by name, never assumed unchanged, and the abstention is reported wherever the result is: coverage the harness could not obtain renders as "not measured" in the bundle, never as a pass. Ratchet measures and decisions are ledger records.
8. `src/core` has zero imports of ambient nondeterminism: no `Date.now`, no `Math.random`, no direct env reads. Inject everything.
9. Secrets never enter the ledger. One detector serves the write-time scrub, the export-time scan, and the secret-scan gate, so the three cannot drift apart. It keys on the assignment name or the field name rather than on the shape of the value, so a numeric-only credential (a PIN, an OTP, an account number) is redacted like any other, and so is a value carried as a JSON number that a text scan would never see. A name is read as a reader reads it, folded through a named list of letters that render as Latin ones, so a credential word spelled with a Cyrillic or fullwidth letter is that word. Structure is shared by construction, not by agreement: where the content is JSON, every site walks it as JSON, so the credential-bearing name reaches nested values and an array directly under one is judged as the one value it is written in pieces of, however those pieces are nested and whichever way that JSON was rendered. A parser and a line scanner cannot be made to agree by adding names, because they disagree about where a value begins, so the line-oriented scan is the fallback for content that is genuinely not JSON and the structural result governs wherever both could apply. What is left is a credential written across the lines of a non-JSON payload, named as a residual in the build guide rather than implied away. Known metric names are exempt by key and never by value: a throughput figure is a measurement whatever its digits. The gate additionally requires a credential-shaped value before it blocks, because scrubbing is fail-safe and blocking is not. A length floor of four characters sits under it, and no lower: a value shorter than the shortest credential anyone issues cannot carry one, so `pw` under a field named `password` travels as written, and everything from four characters up is redacted on the name alone. Four is not a confidence threshold, it is the point below which there is nothing to protect; picking any other number for text is the defect that let a seven-character password through. Name the guarantee honestly wherever it appears: known-pattern scrubbing, not secret removal. Three gaps stay open and stay named: a credential in fields nobody named as a credential, a credential written across the lines of a payload that is genuinely not JSON, and a name spelled out of a script the lookalike list does not carry. The build guide holds them as accepted residuals; they are not closed and nothing here should read as if they were.
10. Zod schema at every boundary: config in, provider responses in, ledger records out, bundle manifest out.
11. The session ledger and blob store live outside the workspace (~/.swarm/sessions/\<id\>/). The sandbox denies tool writes to that path. The signing key lives in the OS keychain, never in the workspace.
12. The planner declares its intended file set as a ledger record before editing, and "before" is checked against ledger order rather than assumed. The file check is set membership plus that ordering: an edit the chain records earlier than the declaration naming it is treated exactly as an out-of-set edit, since a declaration written afterwards describes what was done rather than what was intended. Both are cleared the same way, by an explicit recorded amendment that surfaces in the bundle as a reviewer-visible claim, and an amendment records every file it names rather than only the ones it widened the set by.

## Code Style

- TypeScript strict, ESM, Node 24+. The floor is the coverage cycle: it spawns the runner with `--test-isolation=process`, which Node 22 rejects as a bad option, so the arm measures nothing there.
- Never use em dashes anywhere: code, comments, strings, docs. Use commas, colons, parentheses, or separate sentences.
- No comments that restate the line. Comment only intent, invariants, and non-obvious decisions.
- Descriptive names, no `data`, `result`, `temp`, `helper`, `utils` grab-bags.
- Small modules with one job. If a file needs a section header comment, split it.
- Errors are typed and actionable: what failed, what the user or caller can do.
- Tests accompany every feature in the same change. Test files sit next to sources.
- No new dependencies without a one-line justification in the PR description. Prefer the standard library.

## Non-Goals (do not build these, even if they seem helpful)

No plugin system. No database. No daemon or web server. No multi-agent core (worktree workers are phase 6 only). No blocking LLM-as-judge gates. No custom inference engines. If a task seems to require one of these, stop and flag it instead of building it.

## Definition of Done

A task is done when: `npm run gates` is green with output shown, new behavior has tests, no files outside the declared file set were touched (or the amendment is recorded), no TODO or placeholder markers were introduced, and the diff is the smallest change that satisfies the task. If any of these can't be met, say so explicitly rather than approximating.

/**
 * Reading a bundle back. This is the only input in the system that is genuinely third-party:
 * a bundle is the export format, meant to be carried to another machine and checked by
 * someone who did not produce it, and the embedded verifier is what they run.
 *
 * The threat model is the inverse of every other harness here. Elsewhere the question is
 * whether model output can break the harness recording it; here it is whether a bundle
 * somebody hands you can break the reader that is supposed to be judging it. A reader that
 * throws on a malformed bundle turns "this bundle is not trustworthy", which is a verdict,
 * into a crash, which is not. Invariant 2 makes the read-only claim load-bearing too: replay
 * must never write, so a bundle that induces a write edits the evidence it is being judged
 * against.
 *
 * Structure-aware on purpose. Mutating the manifest bytes directly puts almost every input
 * on the far side of a JSON.parse that fails immediately, and the harness then measures the
 * parse rather than the reader: at raw bytes this reached 12 edges and its corpus did not
 * grow. The input is read as a decision tape instead, choosing among field values that are
 * individually plausible, so a bundle is always well-formed enough to be read and wrong in
 * the ways a real one could be wrong.
 *
 * What is under test:
 *   - a bundle either reads or fails with an error, never with a half-built result
 *   - records and payloads come back in the shapes the caller reads them as
 *   - a broken chain is reported as a problem rather than thrown
 *   - reading writes nothing: the directory is byte-identical afterwards

 * The ratchet's measurement layer. Every number the ratchet compares comes through here:

 *
 * This is the boundary the build guide argues about at greatest length, because a bad read
 * here buys a test deletion. A coverage report that parses as complete when it is truncated
 * reports lines nothing measured as covered; a test-count parser that reads a number a test
 * printed hands the ratchet a measure the code under measurement authored. The defence is
 * that "not measured" is a verdict rather than a pass, and that only holds if a malformed
 * artifact reliably lands there instead of somewhere else.
 *
 * The gate output is untrusted in a specific way worth naming: the harness controls the
 * runner it spawns, but the tests that runner executes are model-written and their stdout is
 * folded into the same stream the reporter writes.
 *
 * What is under test:
 *   - no input makes a parser throw, whatever it is
 *   - a section is only ever returned with line numbers and hit counts that are real numbers
 *   - an incomplete lcov report parses as nothing, never as a section with fewer lines

 * The claim predicate language. This is the one parser in the tree whose input is written

 * Invariant 1 makes the property here unusually sharp. "Missing records, kind mismatches,
 * and unparseable predicates render UNVERIFIED; they never abort the run." So a predicate
 * that cannot be read is a normal outcome with a named error, and any other way out of
 * this function is an invariant violation by definition rather than by judgement. A model
 * that can abort the run by emitting a particular predicate can stop its own work being
 * checked.
 *
 * What is under test:
 *   - parsing settles as a node or as PredicateParseError, never anything else
 *   - evaluating a node the parser accepted never throws, against any payload
 *   - a result is either a boolean verdict or a named failure, never a half-built object

redteam/loop/driver.mjs:3: * Headless driver for the red-team fix/attack loop.
redteam/loop/driver.mjs:4: *
redteam/loop/driver.mjs:5: * One lap is: read the prior lap's attacker report, fill and run the fixer (Claude) on the base
redteam/loop/driver.mjs:6: * branch, run the repo gates, commit; branch a throwaway, fill and run the attacker (Grok) there,
redteam/loop/driver.mjs:7: * commit its findings on that branch, return to base; then route on the two JSONL reports.
redteam/loop/driver.mjs:8: *
redteam/loop/driver.mjs:9: * Two things this driver deliberately cannot do, because the whole exercise depends on them:
redteam/loop/driver.mjs:10: * it never merges a throwaway branch (there is no merge call anywhere in this file), and it never
redteam/loop/driver.mjs:11: * applies the attacker's regression tests or fixes to the base branch. The attacker's work stays
redteam/loop/driver.mjs:12: * on its own branch; the only thing that crosses back to base is the JSONL report, which is held
redteam/loop/driver.mjs:13: * in memory across the checkout and written to state afterwards. Attacker findings become code
redteam/loop/driver.mjs:14: * only by going through a later fixer lap.
redteam/loop/driver.mjs:15: *
redteam/loop/driver.mjs:16: * This driver cuts redteam/loop/lap-<n>, but it records the branch HEAD is actually on when the
redteam/loop/driver.mjs:17: * attacker finishes, which is where the commit lands and may be a branch the attacker cut under
redteam/loop/driver.mjs:18: * it. Every cited regression-test path is then resolved against that recorded branch, so a
redteam/loop/driver.mjs:19: * summary can never name a branch as holding artifacts it does not carry.
redteam/loop/driver.mjs:20: *
redteam/loop/driver.mjs:21: * Routing is not decided here. All exit/wake/continue logic lives in ./evaluate.mjs as pure

 *
 * `reportProblems` carries IO-level failures the driver hit reading a report (no JSONL block, a
 * malformed line, an agent that timed out). They route here rather than in the driver so that a
 * report the driver could not read can never be scored as a quiet lap.
 *
 * `artifactBacking` is what the driver resolved on disk: which cited regression-test paths exist
 * on `attackerBranch`, the branch that actually took the attacker's commits. `checked: false`

tool read ok: # fuzz

Coverage-guided harnesses for the two boundaries where something outside the harness
decides what the code sees: what a model returned, and what reaches the evidence ledger.
Run by crossfire through its Jazzer.js engine, and runnable on their own.

| Harness | Boundary | Invariant under test |
| --- | --- | --- |
| `adapter-output.fuzz.cjs` | a model's tool call arriving at the chokepoint | invariant 3: one execution path, nothing runs unrecorded, and no tool runs on input its schema rejected |
| `ledger-chain.fuzz.cjs` | entries reaching the evidence ledger | invariant 2: append-only and self-verifying, and a refused entry leaves the chain where it was |
| `swarm-toml.fuzz.cjs` | `swarm.toml` reaching the config parser | parsing settles as a config or a `MalformedSwarmTomlError`, and no input reaches `Object.prototype` |

The TOML one earns its place differently from the other two: a scanner alleged prototype
pollution in `valueAt`, and the refutation on record is a probe someone ran once.
Jazzer.js's prototype-pollution detector is on by default, so every input re-runs that
refutation. The detector was confirmed to fire here by injecting a real pollution into the
build and watching the harness report it.

## Why there is a build step

Jazzer.js instruments what it loads through `require`, and its require hook does not
understand TypeScript. Imported directly, `src/**/*.ts` loads but is never instrumented:
the fuzzer then runs blind, which looks exactly like a run that found nothing. Measured on
the same harness and budget, blind is `cov: 3` and coverage-guided is `cov: 37`.

`npm run fuzz:build` emits `src` to `.swarm/fuzz-build` as JavaScript with inline source
maps. The harnesses require that, so Jazzer.js instruments it, and the inline maps mean a
crash still reports its location in the original `.ts`.

## Running one

```sh
npm run fuzz:build
mkdir -p .swarm/corpus && cp fuzz/corpus/ledger-chain/* .swarm/corpus/
node_modules/.bin/jazzer fuzz/ledger-chain.fuzz.cjs .swarm/corpus \
  -- -max_total_time=60 -artifact_prefix=.swarm/
```

Fuzz a copy, not `fuzz/corpus` itself: the fuzzer writes every interesting input it
finds back into the directory it was given, so pointing it at the seeds buries them in
a few hundred generated files. crossfire copies the corpus to a temp directory for the
same reason. `-artifact_prefix` keeps crash files out of the repo root the same way.

Exit 77 is a crash, and the input that caused it lands in `.swarm/crash-<sha1>`.

## The smoke check

```sh
node fuzz/smoke.mjs
```

Loads every harness and runs it once over each of its own seeds. A harness that throws on
startup, or one built against a stale `.swarm/fuzz-build`, produces the same clean output
as a harness that genuinely found nothing, so `fuzz:build` runs this before handing
anything to the fuzzer.

## Corpora

Each corpus holds realistic valid inputs plus malformed ones, so the fuzzer starts inside
the shapes the code actually accepts rather than having to discover them. Seeds are read
as one model turn: JSON where it parses, raw text where it does not.
