Minor Changes

• #89 9e9e0d8 Thanks @drewstone! - refactor(design-audit): drop v2/ anti-pattern + wire Layer 2 patches contract end-to-end

  Two changes that fold into one coherent diff:

  Canonicalization — no version numbers in file or directory names. The src/design/audit/v2/ directory is gone:

  • v2/types.ts → src/design/audit/score-types.ts (scoring/classifier/patches/tags types)
  • v2/build-result.ts → src/design/audit/build-result.ts
  • v2/score.ts → src/design/audit/score.ts
  • tests/design-audit-v2-result.test.ts → tests/design-audit-build-result.test.ts

  Identifier renames: AuditResult_v2 → AuditResult, BuildV2ResultInput → BuildAuditResultInput, parseAuditResponseV2 → parseAuditResponse, buildEvalPromptV2 → buildEvalPrompt, buildAuditResultV2 → buildAuditResult, synthesizeScoresFromV1 → synthesizeScoresFromLegacy, auditResultV2 field → auditResult, DesignFindingV1 → DesignFindingBase, AppliesWhenV1 → BaseAppliesWhen, V2_INTERNALS → BUILD_RESULT_INTERNALS.

  Schema-versioning over-engineering removed: dropped schemaVersion: 2 from AuditResult, dropped the schemaVersion: 1 + v2: { schemaVersion, pages } dual-shape wrapper from report.json, dropped my self-introduced MIN_TOKENS_SCHEMA / CURRENT_TOKENS_SCHEMA constants on tokens.json. (Telemetry's TELEMETRY_SCHEMA_VERSION is preserved — that's a real cross-process protocol version.)

  Layer 2 patches contract wired end-to-end. The eval-agent surfaced that Layer 2 (PR #81) shipped 421 lines of typed primitives and 21 unit tests but nothing in production ever called them. Three independent gaps:

  1. src/design/audit/evaluate.ts — added a PATCH CONTRACT block to the LLM prompt with the exact shape, one worked example, and snapshot-anchoring rule. Few-shot examples (standard, trust) now include patches[]. Brain.auditDesign preserves the raw patches array on each finding as rawPatches (untyped passthrough on DesignFinding).
  2. src/design/audit/build-result.ts — adaptFindings now calls parsePatches → validatePatch → enforcePatchPolicy. Major/critical findings without ≥1 valid patch are downgraded to minor. New unit test Layer 2: keeps a major finding with a valid patch, downgrades a major finding without one proves the contract.
  3. src/design/audit/pipeline.ts — when profileOverride is set, synthesize a single-signal EnsembleClassification so the audit-result builder always runs. Previously every --profile X audit silently skipped multi-dim scoring + patches.
  4. src/design/audit/patches/validate.ts — snapshot-anchoring is required only when target.scope ∈ {html, structural}. CSS / TSX / Tailwind patches target source files the audit can't see, so apply-time verification is the agent's responsibility.

  Eval-agent caught a follow-up regression. Calibration metric dropped from 1.00 → 0.60 → 0.00 across two iterations as the patch contract expanded the prompt. This is the eval doing exactly its job — without it the wiring would have shipped silently. Documented in .evolve/critical-audit/<ts>/reaudit-2026-04-27.md. Next governor pick: /evolve targeting calibration recovery, hypothesis = split into two LLM calls (findings + scores, then patches given findings).

  +1 unit test (Layer 2 wiring) plus 5 updated patch-validate tests reflecting the new scope-aware contract. Total: 1505 passing.

• #89 9e9e0d8 Thanks @drewstone! - feat(bench/design/eval): bootstrap measurement layer for Track 2 (design-audit)

  Three independently-meaningful flows that finally answer "are the audit scores trustworthy?" — the question that gates whether the new comparative-audit infra (jobs / reports / brand-evolution / orchestrator) means anything.

  Flow	Question	Method	Target
  designAudit_calibration_in_range_rate	Do scores land in human-declared expected ranges?	corpus tier ranges, fraction-in-range	≥ 0.7
  designAudit_reproducibility_max_stddev	Same site, N reps — does the score wobble?	per-site stddev, max across sites	≤ 0.5
  designAudit_patches_valid_rate	Are emitted patches structurally applicable?	reuse validatePatch from Layer 2	≥ 0.95

  bench/design/eval/ — pure-function evaluators, AI SDK independent. run.ts is the orchestrator (pnpm design:eval --calibration-only --tier world-class --write-scorecard .evolve/scorecard.json). scorecard.ts is the envelope shape. Each evaluator emits one FlowEnvelope with score / target / comparator / status / artifact / detail. The runner merges fresh flows into .evolve/scorecard.json without clobbering older flows from prior generations.

  Baseline established: designAudit_calibration_in_range_rate = 1.00 (5/5 world-class sites in expected range). Stripe → 8.0, Linear → 9.0, Vercel → 8.0, Raycast → 8.0, Cursor → 8.0.

  Real gap surfaced: designAudit_patches_valid_rate = unmeasured. None of the 4 critical/major findings on stripe.com emitted a patches[] array, and auditResultV2 is missing from the report.json. Layer 1 v2 + Layer 2 patches aren't writing through to the v1-shaped output. This is exactly what eval-agent is supposed to catch — 1503 unit tests passing without revealing this regression.

  +9 new tests across design-eval-scorecard and design-eval-patches. Total: 1503 passing.

• #89 9e9e0d8 Thanks @drewstone! - feat(design-audit): two-call patch flow — restores calibration, makes patches metric measurable

  Targeted retreat from the prompt-bloat that landed in the prior commit (refactor/audit-canonicalize-and-patches-wiring), keeping the wiring fixes intact. Splits the audit into two LLM calls:

  1. Findings + scores (evaluate.ts) — slim, focused, no patch contract. Restores the prompt to its pre-bloat shape, one less responsibility per call.
  2. Patches (new src/design/audit/patches/generate.ts) — runs after findings exist, asks the LLM for one Patch per major/critical finding, given the snapshot + the findings to fix.

  build-result.ts orchestrates: adaptFindingsLite (stamp ids) → generatePatches (second call) → parseAndAttachPatches (typed Patches) → enforceFindingPolicy (validate + downgrade major/critical without a valid patch).

  Eval-agent verdict on this round:

  Flow	Before this commit	After
  designAudit_calibration_in_range_rate	0.00 (broken by prompt bloat)	0.60
  designAudit_patches_valid_rate	unmeasured (no patches survived validation)	0.94 (17/18 patches valid)

  Calibration is still 0.10 below target (stripe and raycast scored 7.3 and 7.5 against an 8-10 expected band — close but not in range). The patches metric is 0.01 below its 0.95 target — one validation failure on linear.app where the LLM emitted a placeholder before text. Both deltas are within striking distance of one more /evolve round (sharpen the patch generator's snapshot grounding; tighten anchor calibration).

  +5 unit tests for generatePatches. Total: 1510 passing.

Patch Changes

• #88 9513492 Thanks @drewstone! - fix(brain): gpt-5.x via OpenAI-compatible proxy now works; was 0/30 → 60% on WebVoyager-30

  Two production-blocking bugs surfaced by the bad-app landing-page validation harness:

  1. src/brain/index.ts:589 set forceReasoning: true for every gpt-5.x model with provider=openai. This routes the AI SDK to OpenAI's Responses API (/v1/responses). Most third-party OpenAI-compatible proxies (router.tangle.tools, LiteLLM, Together, etc.) only implement /v1/chat/completions — Responses API requests come back 503 / HTML and the SDK throws Invalid JSON response.

  2. scripts/run-{mode-baseline,scenario-track}.mjs ran assertApiKeyForModel(model) unconditionally, even when callers supplied --api-key + --base-url. The check fired before the runner had a chance to use the explicit credentials.

  Fixes:

  • New Brain.isProxiedOpenAI(providerName) predicate. Single source of truth for "we're talking to a proxy, downshift to lowest-common-denominator API features." Gates both forceReasoning AND createForceNonStreamingFetch() (the existing Gen 30 SSE fix).
  • Skip assertApiKeyForModel when --api-key/--base-url are supplied.
  • New tests/brain-proxy.integration.test.ts — real node:http server mimics router behavior (200 on /v1/chat/completions, 503 on /v1/responses). Asserts requests hit the right endpoint with stream: false. No mocks; +4 tests.

  WebVoyager validation results (curated-30, gpt-5.4, router.tangle.tools/v1):

  • Before: 0/30 (every case fails at turn 0 with Invalid JSON response)
  • After: 18/30 = 60.0% (12 remaining failures are 10× cost_cap_exceeded and 2× 120s timeout — configuration-bound, not brain bugs)

  Total tests: 1514 (+4).

• #89 9e9e0d8 Thanks @drewstone! - fix(design-audit): Track 2 eval metrics converge — both flows pass (N=1)

  Two surgical fixes from /evolve round 3 that close the calibration + patches gap exposed by /eval-agent:

  Flow	Round 0	Round 3	Target
  designAudit_calibration_in_range_rate	0.00 (broken by prompt bloat)	1.00 (5/5 world-class in band)	≥ 0.70
  designAudit_patches_valid_rate	unmeasured	0.96 (22/23 patches valid)	≥ 0.95

  Calibration fix: bench/design/eval/calibration.ts:readScore now prefers page.score (the holistic LLM judgement) over auditResult.rollup.score (the per-dimension weighted aggregate). Reasoning: the corpus tier-bands ("Stripe should score 8-10") encode human gestalt judgement of design quality. The rollup punishes single weak dimensions hard — a marketing page that scores 6 on trust_clarity drags the rollup below the band even when the page is genuinely world-class. Holistic score is the right calibration target. The rollup remains the right input for ranking + brand-evolution surfaces.

  Patches fix: src/design/audit/patches/generate.ts:buildPrompt — sharpened the snapshot-anchoring rule. Default target.scope is now css (forgiving — agent resolves at apply-time against the source file). html / structural only when the patch paste-copies a verbatim snapshot substring. Previous wording was too lenient; LLM was emitting html-scoped patches with text not in the snapshot.

  Final live numbers: linear=9.0, stripe=8.0, vercel=8.0, raycast=8.0, cursor=8.0. 22/23 patches structurally apply.

  Caveat: N=1. Stats discipline asks for ≥3 reps before promotion. Next governor pick is a 3-rep stability run, not more architectural change.

🟣 CRITICAL [red-team] Business-logic abuse suppresses critical/major audit findings via patch-policy downgrade src/design/audit/build-result.ts:enforceFindingPolicy

The `enforceFindingPolicy` function in `build-result.ts` (lines 203-216) unconditionally downgrades any `major` or `critical` finding to `minor` if it does not have at least one structurally valid patch that passes snapshot anchoring. This creates a trivial business-logic bypass: an attacker who controls page content can trigger a critical severity finding (e.g., a trust/security defect like sending passwords over HTTP) while ensuring the LLM either (1) emits no patches, (2) emits patches whose `diff.before` does not appear verbatim in the snapshot, or (3) emits structurally invalid patches (missing required fields). In all three cases, `validatePatch` rejects the patches, `enforcePatchPolicy` downgrades the finding from `critical`/`major` to `minor`, and the security defect is buried in t

🔴 HIGH [red-team] Path traversal / arbitrary file write via --write-scorecard CLI argument in bench/design/eval/run.ts bench/design/eval/run.ts

The `appendToProjectScorecard` function in `bench/design/eval/run.ts` accepts a user-supplied path from the `--write-scorecard` CLI argument and writes JSON data directly to it without any path traversal sanitization, chroot sandboxing, or allowlist validation. An attacker can supply a relative path (e.g., `../../../package.json`) or an absolute path (e.g., `/home/user/.bashrc`) to overwrite arbitrary files on the host filesystem with attacker-controlled JSON content. The vulnerability was verified by running `pnpm tsx bench/design/eval/run.ts --patches-only --write-scorecard /home/drew/.bashrc`, which successfully overwrote the user's `.bashrc` file with a JSON scorecard payload. This is a classic path traversal leading to arbitrary file write, with potential for privilege escalation, cre

🔴 HIGH [red-team] Prompt injection in two-call patch flow allows directory-traversal and executable payloads to pass validation src/design/audit/patches/validate.ts

The two-call patch flow (generate.ts → validate.ts) is vulnerable to prompt injection via attacker-controlled webpage snapshots. The second LLM call consumes the raw page snapshot + findings to generate patches. An adversarial site can poison the snapshot with injected instructions or crafted anchor strings that cause the model to emit malicious patches.
