Two defects found and fixed in a hostile review of the whole package: 1. The ROI report generator trusted the ledger verdict field and would mint a clean $16,886/year report for phase2-comrak-010 — the memory-leaking patch the audit overturned (immutably 'accepted' in the append-only ledger, sanitizers_clean:false). report_row now exposes sanitizers_clean and the report treats accepted-but-not-sanitizer-clean as NOT shippable, printing a warning before any dollar figure. Legit wins (sanitizers_clean:true) still render clean. 2. bench-runner service --rate 0 / --count 0 could panic via from_secs_f64(1/0); run_session now guards finite/positive rate and non-zero count/workers. Attacks correctly refused (verified, no change): ledger UPDATE/DELETE, propose_patch ../ + .git escapes, read_target_source traversal. All 10 accepted rows satisfy the green-gates + CI>=1.02 invariant. Findings recorded in results/adversarial-review.md.

# Adversarial review — whole package
|
|
|
|
A hostile pass over the entire project: every headline claim re-checked
|
|
against the ledger, the trust boundary attacked directly, the newest
|
|
code scrutinized hardest, and the statistics re-validated. Two real
|
|
defects found and fixed; the load-bearing guarantees held.
|
|
|
|
## Findings
|
|
|
|
### 1. FIXED — the ROI generator minted a clean pitch for an overturned patch
|
|
The report generator trusted the ledger's `verdict` field. `phase2-comrak-010`
|
|
is immutably `accepted` (it predates the machine-enforced sanitizer gate;
|
|
the audit overturned it for a LeakSanitizer leak and it was never banked).
|
|
`report --run-id phase2-comrak-010` therefore produced a clean
|
|
**$16,886/year** ROI report for a memory-leaking patch — exactly the kind
|
|
of self-contradiction a hostile reviewer would seize on.
|
|
|
|
**Fix:** the report now treats an `accepted` row that is not
|
|
`sanitizers_clean` as **not shippable** and prints a "Not shipped" warning
|
|
before any dollar figure. Because the pipeline now enforces ASan/UBSan on
|
|
every accept, all legitimate wins are `sanitizers_clean: true`; only the
|
|
historical overturned row is `accepted + false`, so the rule cleanly
|
|
separates them. Regression-checked: `phase3-cjson-002` still renders clean.
|
|
|
|
### 2. FIXED — load generator could panic on degenerate inputs
|
|
`bench-runner service --rate 0` (or `--count 0`) reached
|
|
`Duration::from_secs_f64(1.0/0.0)` → panic. **Fix:** `run_session` now
|
|
rejects a non-finite/non-positive rate and zero count/workers with a clear
|
|
error.
|
|
|
|
## Attacks that were correctly refused (no change needed)
|
|
|
|
- **Ledger append-only:** `UPDATE`/`DELETE` on a copy both refused by the
|
|
SQLite triggers.
|
|
- **Patch boundary:** `propose_patch` refused `../` traversal and `.git`
|
|
access; `read_target_source` refused traversal. A patch can only touch
|
|
`targets/<t>/workspace`.
|
|
- **Accepted-row invariant:** all 10 `accepted` rows have green upstream
|
|
tests + golden replay and a bootstrap CI lower bound ≥ 1.02.
|
|
- **Statistics:** every batch and service A/A calibration is a null result
|
|
(0 false positives); every injected-5% regression is detected (≥95%).
|
|
The service load generator is coordinated-omission-correct and its
|
|
injection test resolves a known 5% latency regression 10/10.
|
|
|
|
## Verification run
|
|
|
|
`cargo test --workspace` (all green), `clippy -D warnings` (clean),
|
|
`cargo fmt --check` (clean). Every case-study and CLAUDE.md figure
|
|
re-checked against `results/ledger.sqlite` and the calibrated bench —
|
|
consistent, with the compound tokei figure stated as an approximation
|
|
(CIs don't multiply) and p99 service latency explicitly not claimed.
|
|
|
|
## Standing (not defects)
|
|
|
|
- `phase2-comrak-010` remains `accepted` in the ledger by design — the
|
|
ledger is append-only and records what happened; the overturn lives in
|
|
the case study and is now enforced by the report generator too.
|
|
- `phase0-comrak-002` (mimalloc) is `needs-human-review`, awaiting a ruling
|
|
(see `results/rulings/`).
