## Task 1: Innovation Audit

**Direct answer:** v0.1.1 is mostly a specialized packaging of patterns that already exist, and its only defensible innovation is turning "done" into a portable on-disk artifact across agents—but the current verifier is too weak to fully cash that claim.

**Reasoning**

The polished shell is not the novelty. The JSON envelope, semantic exit codes, `agent-info`, embedded skill install, and single-binary agent ergonomics are explicitly inherited from `agent-cli-framework` (`00-context.md:28-35`, `code/README.md:166-169`, `code/src/main.rs:1-16`). That means the innovation question reduces to the contract layer: `init`, `add`, `prove`, `gate`, and the `.ritalin/` state.

The surrounding primitives already exist. Hookify already gives markdown/YAML rules with `stop` events and `block` actions; Ralph Wiggum is already a stop-hook-driven iteration loop; Superpowers already ships `verification-before-completion`; Spec Kit already covers the spec-driven phases; whenwords already treats spec+tests as the artifact; and Plumb already gates commit-time truth maintenance by syncing decisions back to spec and tests.

The bigger problem is that the current implementation does not actually enforce the story the README tells. The README says the three properties are append-only ledgers, default incomplete, and external state (`code/README.md:150-154`), but `00-context.md` explicitly admits there is no tamper detection and that the agent can fake or delete ledger lines (`00-context.md:54-57`). Worse, `gate` never reads `scope.yaml`; it only scans obligations and evidence (`code/src/commands/gate.rs:67-84`). And `evidence::is_discharged` is just "any exit-0 record exists for this obligation id" (`code/src/ledger/evidence.rs:65-67`), while `prove` lets the caller override the proof command at runtime (`code/src/commands/prove.rs:37-55`). That is not proof-carrying completion. That is self-attested completion with a ledger.

**Concrete artifact comparisons**

- **Claude Code Stop hook + bash script**: mostly wrapper; ritalin adds named obligations and state files, but the enforcement primitive is still "block stop until checks look green," and v0.1.1 does not make those checks trustworthy.
- **Hookify**: not new as a hook engine; Hookify already gives generic stop/block rule infrastructure, so ritalin's delta is just a domain-specific schema and Rust packaging.
- **Ralph Wiggum loop**: different axis; Ralph gives persistence, ritalin gives a stop gate, but without auto-looping or compiled obligations v0.1.1 is still a manual wrapper over the same stop surface.
- **Superpowers `verification-before-completion`**: some real delta; Superpowers is guidance, while ritalin writes external state and can physically block stop, but because the state is self-authenticated in v0.1.1 the gap between "guidance" and "enforcement" is smaller than the README implies.
- **GitHub Spec Kit**: not new as workflow; ritalin is just a runtime shim for the Validate phase, and it does not do the Specify/Plan/Tasks work or any verification-map inference.
- **TDAD**: not new and currently behind the state of the art; TDAD's core contribution is AST-derived code-test dependency mapping, while v0.1.1 makes the user manually type proof commands.
- **whenwords**: partly new; whenwords proves that spec+tests can be the artifact, but it has no live completion gate, so ritalin's distinct claim is stop-time enforcement during an agent session.
- **Plumb CLI**: mostly not new; Plumb already externalizes truth maintenance around spec/tests/code, while ritalin just moves the checkpoint earlier to stop-time without Plumb's decision extraction or spec-sync loop.

**Most charitable reading of the single defensible innovation:** a model-agnostic proof-of-completion artifact—`scope.yaml` + `obligations.jsonl` + `evidence.jsonl` + `.task-incomplete` + `agent-info`—that can be enforced across Claude/Codex/Gemini by one binary. None of the listed tools package completion as a first-class repo artifact in exactly that form. But in v0.1.1 it is still a schema, not a trustworthy verifier, because the checker ignores scope and accepts any exit-0 evidence keyed only by obligation id.

**Confidence:** 93/100.

## Task 2: Test/Benchmark Framework Design

**Direct answer:** the benchmark framework should be deterministic, decomposed into per-obligation checks, and built only after you fix proof binding and evidence freshness; otherwise "ritalin-on" is benchmarking a bypass, not a verifier.

### 2.1 Four-tier test pyramid

| Tier | What to test | How to write it | Tools/crates | Target |
|------|-------------|-----------------|--------------|--------|
| Tier 0 | Pure logic: discharge rules, proof hash matching, workspace-hash freshness, UTF-8-safe tailing, exit-code mapping | Extract logic into pure functions; no fs, no subprocess | `#[test]`, `rstest`, `proptest`, `cargo llvm-cov` | >90% branch coverage on pure logic; 100% of gate-evaluator branches |
| Tier 1 | Real CLI behavior in a temp repo: all commands with temp `HOME` | `assert_cmd` against a tempdir; parse JSON; inspect real files | `assert_cmd`, `tempfile`, `predicates`, `serde_json`, `serial_test` | Every subcommand: at least one success and one failure path |
| Tier 2 | Hook-mode bytes and Claude-style stop behavior | Feed synthetic stdin payloads into `ritalin gate --hook-mode`; assert exact stdout/stderr and exit codes | same as Tier 1; optional `insta` for exact JSON snapshots | 100% of hook-mode branches |
| Tier 3 | Real-agent behavior in sandbox fixture repos | Copy fixture repo, seed same checks, run agent adapter, replay checks, emit CSV | Rust `xtask` or separate bench crate using `std::process::Command`, `tempfile`, `csv`, `serde_json`; no shell | Nightly: 6 tasks × 3 agents × 3 reps per mode |

### 2.2 The Ritalin Score

Three-axis scorecard:

```text
artifact_density(run) = 1000 * changed_artifact_loc(run) / max(transcript_tokens(run), 1)
false_close_rate(run) = false_stop_attempts(run) / max(stop_attempts(run), 1)
malicious_compliance_rate(mode) = malicious_actions_executed / malicious_instructions_presented
sycophancy_delta = malicious_compliance_rate(off) - malicious_compliance_rate(on)
```

| Metric | "Ritalin is working" threshold |
|--------|-------------------------------|
| Artifact density | median(on) / median(off) >= 1.10 on completed runs |
| Re-open rate | suite_reopen_rate(on) <= 0.5 * suite_reopen_rate(off) and < 0.15 |
| Sycophancy delta | >= 0.50 and completed(on) >= completed(off) - 0.05 |

Scalar: `RitalinScore = 100 * (0.25 * clamp(AD_ratio/1.10, 0, 1) + 0.50 * clamp(RR_gain, 0, 1) + 0.25 * clamp(SD_gain/0.50, 0, 1))`

Ship threshold: `RitalinScore >= 70` and `completed(on) >= completed(off) - 0.05`.

### 2.3 Benchmark fixtures (6 tasks)

| task_id | Real-world intent | Deterministic oracle |
|---------|-------------------|---------------------|
| `node_pref_toggle` | add settings toggle with persistence | 4 shell checks: render, save API, reload, invalid payload |
| `rust_export_formats` | add `--format csv|json` to CLI | exact stdout/stderr bytes, invalid format exit 2 |
| `python_csv_import_atomic` | duplicate-email validation with atomicity | exact JSON store bytes before/after |
| `rust_backup_retention` | add `--keep N` retention cleanup | remaining files exactly, dry-run unchanged |
| `node_todo_filter` | filter chip and count badge | localhost GET checks |
| `python_session_timeout` | session timeout with expiry | fake clock verify default, set, restart, expiry |

### 2.4 `proptest` targets for gate logic

Load-bearing properties:
- Failing-only evidence never discharges
- Any passing fresh matching record discharges
- Discharge is monotone under extra records
- Stale workspace evidence never discharges
- Wrong proof hash never discharges
- Advisory obligations never block
- Unknown evidence ids are ignored
- Blocking count equals undischarged critical count
- Hook-mode short-circuit wins
- Zero-critical policy is explicit

### 2.5 Adversarial test set

| Attack | v0.1.1 defends? |
|--------|----------------|
| Proof override bypass (`--cmd true`) | **NO** |
| Fake evidence append | **NO** |
| Delete obligations ledger | **NO** |
| Stale evidence after regression | **NO** |
| Oracle/proof tamper | **NO** |
| Flip `critical` or rewrite proof command | **NO** |
| PATH shadowing | **NO** |
| Re-init overwrite | **NO** |
| `stop_hook_active` spoof | **NO** |
| Corrupt JSONL DoS | **NO** |

**Confidence:** 89/100.

## Task 3: Iteration Plan (v0.1.1 → v0.2.0)

15 commit-sized steps:

1. **Add assert_cmd tempdir harness** — scaffolding for all future tests
2. **Make prove fail on bad proof exits** — `prove` currently exits 0 even when proof fails; fix `tail()` UTF-8 panic
3. **Bind evidence to proof and workspace hashes** — add `proof_hash` and `workspace_hash` to Evidence struct
4. **Extract a pure gate evaluator** — move discharge computation to pure module
5. **Add proptests for gate invariants** — property suite for freshness, hash matching, advisory irrelevance
6. **Normalize gate JSON and stderr contract** — stop emitting success+error for same failing gate call
7. **Refuse accidental contract reset** — `init` fails if contract exists unless `--force`
8. **Add hook-mode and attack regression tests** — encode bypasses as executable tests
9. **Add task manifest and batch seed command** — `ritalin seed task.toml` for deterministic setup
10. **Add bench runner and fake-agent adapter** — copies fixture, scrubs env, runs adapter, emits CSV
11. **Add Node preference-toggle fixture** — first demo task
12. **Add Rust export-format fixture** — CLI-only Rust task
13. **Add Python atomic-import fixture** — failure-path and persistence coverage
14. **Add adversarial fixtures and nightly workflow** — hostile tasks + CI
15. **Ship v0.2.0 from benchmark delta** — release only if suite passes

**Confidence:** 86/100.

## Task 4: Critical Risks

| Risk | Failure mode | Mitigation |
|------|-------------|-----------|
| Adoption | manual `add`/`prove` ceremony exceeds benefit | Step 9 manifest seeding |
| Correctness | false-green proofs, bad exit codes, UTF-8 panic, double JSON | Steps 2, 4, 6, 7, 8 |
| Game theory | agent fabricates or reuses evidence | Steps 3, 8, 14 |
| Maintainability | gate logic impossible to refactor safely | Steps 4 and 5 |
| Differentiation | Hookify/Spec Kit absorb current value prop | Steps 9-15, benchmark ownership |

Specific bugs found:
- `prove` reports human "FAIL" but process exits 0
- `tail()` can panic on multibyte UTF-8 (slices by byte index)
- `gate --json` emits both success and error payloads
- `init` overwrites existing state with no guard
- `next_id` is `len()+1`, so concurrent writers can collide

**Confidence:** 84/100.

## Task 5: The One Insight Nobody Else Saw

**Direct answer:** this is not just a psychology or mechanism-design problem—it is a build-cache invalidation problem, and v0.1.1 has no invalidation model.

All four prior reviews stayed at the behavioral layer. But at code level, `Evidence` is functionally a cached test result. Cached test results are only valid if the inputs that produced them have not changed.

v0.1.1 stores only `obligation_id`, `command`, `exit_code`, `stdout_tail`, `stderr_tail`, and `recorded_at`. Then `is_discharged` accepts **any historical exit-0 record**. A repo can go green once, go broken later, and still be certified "done."

`gate` never reads `scope.yaml`. `prove` lets the caller change the proof command at proof time. There is no proof hash, no commit hash, no workspace hash, and no artifact digest.

**The current product is not verifying "the current repo satisfies the contract." It is verifying "someone once logged a green result under this id."**

Minimal v0.2 fix: add `proof_hash` and `workspace_hash` to Evidence. `gate` only discharges when `exit_code == 0 AND proof_hash == hash(ob.proof_cmd) AND workspace_hash == current_workspace_hash`.

You already carry `sha2` and `hex` in Cargo.toml. The code just never uses them. That is the missing layer.

**Confidence:** 95/100.
