feat(design-audit): 8-layer architecture (Layers 1-7 + L8 scaffold)#81
Conversation
…ture src/design/audit/v2/types.ts — comprehensive TypeScript interfaces covering all 8 layers from the RFC (docs/rfc/design-audit-world-class.md): Layer 1 — DimensionScore, RollupScore, ClassifierSignal, EnsembleClassification, DomHeuristics Layer 2 — Patch, PatchTarget, PatchDiff, PatchTest, PatchRollback, DesignFinding (extended with id, dimension, patches, kind) Layer 3 — NovelPatternObservation Layer 4 — PatchApplication, PatchReliability Layer 5 — Pattern, PatternScaffold, PatternFleetEvidence, PatternQuery, PatternMatch Layer 6 — AppliesWhen extended (audience, modality, regulatoryContext, audienceVulnerability), tag enums Layer 7 — EthicsRule, EthicsDetector, EthicsViolation, EthicsCategory Layer 8 — Modality, ModalityInput, SurfaceMeasurements, SurfaceRecord, Evidence, ModalityAdapter Top-level — AuditResult_v2, AuditRuntimeHints Phase 0 is the stable contract that lets Wave 1 + Wave 2 implementation work proceed in parallel without diverging interfaces. Editing this file mid-build is a coordinated change; layers must update in lockstep. Invariants enforced: - Every score is DimensionScore with range + confidence - Every major/critical finding MUST have >=1 Patch - Every patch has both target (what changes) and testThatProves (how we verify) - Every classification carries explicit ensembleConfidence + signalsAgreed - Pattern, ethics, modality types compose via shared AppliesWhen
…Layer 8 scaffold Full implementation of RFC-002: World-Class Design Audit. Primary consumer is coding agents (Claude Code, Codex, OpenCode, Pi); architecture is JSON-first, tool-callable, and self-explaining when uncertain. Layer 1 — Multi-dimensional scoring: ensemble classifier (URL + DOM heuristic + LLM tiebreaker), 5 universal dimensions, per-page-type rollup weights and calibration anchors, AuditResult_v2 shape. Layer 2 — Patch primitives: every major/critical finding ships patches[] with target, diff.before/after, testThatProves, rollback, estimatedDelta. Severity enforcement downgrades major/critical without valid patches to minor. Layer 3 — First-principles fallback: fires when ensembleConfidence < 0.6 or signals disagree; scores against 5 universal product principles only; emits NovelPatternObservation to ~/.bad/novel-patterns/. Layer 4 — Outcome attribution: append-only JSONL store, ack-patch + --post-patch close-the-loop, patchHash cross-tenant grouping, aggregatePatchReliability. Layer 5 — Pattern library (scaffold): types/store/mine/match + CLI query/show. Cold start until ~6 weeks fleet data; mine threshold N≥30, ≥5 tenants, rate≥0.7. Layer 6 — Composable predicates: AppliesWhen extended with audience/modality/ regulatoryContext/audienceVulnerability; 9 new rubric fragments; loader matches on context flags --audience/--modality/--regulatory/--audience-vulnerability. Layer 7 — Domain ethics gate: 4 rule files (medical/kids/finance/legal) with citation-backed rules; hard rollup floor critical→4, major→6; preEthicsScore preserved; --skip-ethics bypass (test-only, logged). Layer 8 — Modality adapters (scaffold): HTML adapter wraps existing Playwright pipeline; iOS/Android throw NotImplementedError; --modality dispatch. +40 new tests across patch-parse, patch-validate, first-principles, attribution. Total: 1393 passing.
… blob, health domain in medical rules Three fixes discovered during smoke testing: 1. ethics/rules/*.yaml were not being copied to dist/ at build time — copy-static-assets.mjs only copied rubric fragments and anchors. Added ethics rules entry so the gate actually loads its rules at runtime. 2. pageTextBlob included the request URL in the content blob, causing false negatives on pattern-absent rules: a URL like medical-no-dosage.html contains "dosage" and suppressed the dosage-warning-required rule. URL is now excluded from the blob; URL-based classification uses the ensemble classifier's own URL heuristic. 3. Medical ethics rules matched domain: [medical, clinical, pharmacy] but the LLM classifies pharmacy-style ecommerce pages as domain "health". Added "health" to the domain list so the rules apply correctly.
…try rollup tests PR #79 added two telemetry-rollup-remote tests that spawn `node --experimental-strip-types ROLLUP_PATH`. That flag is fully supported only on Node 22+; on Node 18 and 20 (both in our CI matrix), Node exits 9 (invalid argument) before the rollup script runs, so the tests assert exit 2 but get exit 9. Replace with `tsx` (added as a devDependency) which works identically across all Node versions. The behavior under test is unchanged: rollup --remote without BAD_TELEMETRY_API / BAD_TELEMETRY_ADMIN_BEARER must exit 2 with a clear stderr message.

Bug 1 — forceReasoning routes through unsupported endpoint src/brain/index.ts:589 set forceReasoning: true for every gpt-5.x model with provider=openai. AI SDK routes those to OpenAI's Responses API (/v1/responses). router.tangle.tools and most OpenAI-compatible proxies only implement /v1/chat/completions — the Responses API call returns 503 / HTML and the SDK throws Invalid JSON response. Bug 2 — env-var assertion fires despite explicit credentials 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 creds, breaking the WebVoyager harness. Fixes Brain.isProxiedOpenAI(providerName) — single predicate for "we're talking to a proxy, downshift to lowest-common-denominator features." Gates BOTH forceReasoning AND createForceNonStreamingFetch(). Skip assertApiKeyForModel when --api-key/--base-url are flag-supplied. tests/brain-proxy.integration.test.ts — real node:http server mimics router behavior (200 on chat-completions, 503 on responses). Asserts requests hit the right endpoint with stream:false. +4 tests. WebVoyager validation (curated-30, gpt-5.4, router.tangle.tools/v1): Before: 0/30 every case fails Invalid JSON response After: 18/30 = 60.0% (12 fails are cost_cap_exceeded, not brain bugs) The 60.0% is curated-30, n=1, single quick run. Per the cost-cap-confound note in .evolve/current.json:gen30r3, bumping the cap to 150k should flip most of the 10 cost_cap failures to pass. Don't update landing page copy until that's verified ≥3 reps. Critical-audit log: .evolve/critical-audit/2026-04-27T08-14-37Z/ Total tests: 1514 (+4 brain-proxy integration). * fix(runner): bump DEFAULT_TOKEN_BUDGET 100k → 300k to match gpt-5.4 verbosity The 100k cap was set in Gen 9 to bound runaway recovery loops (Gen 8.1 death-spirals at 130-173k tokens / $0.25-$0.32 per case). It was calibrated for gpt-5.2-era brain output. gpt-5.4 is materially more verbose per turn — Gen 30 R3 measured cost_cap_exceeded as the dominant WebVoyager failure mode at the old cap. Validation evidence (curated-30, gpt-5.4 via router, Brain.isProxiedOpenAI gate already in place from earlier in this PR): cap 100k: 18/30 (60.0%) 10× cost_cap_exceeded, 2× timeout cap 300k: 26/30 (86.7%) 0× cost_cap_exceeded, 3× timeout, 1× capability The 8.7-percentage-point lift comes entirely from cost-cap-bound runs flipping to pass — every one of those 10 cases was on a successful trajectory and just needed budget. Override paths preserved: - BAD_TOKEN_BUDGET env var still wins per the Gen 30 R3 logic in RunState constructor (operator dial overrides hard-coded defaults). - Per-case Scenario.tokenBudget still wins when set explicitly by callers like benchmark configs. Operators who deliberately want a lower cap (cost-sensitive batch jobs, test fixtures, free-tier validation) can still set BAD_TOKEN_BUDGET=100000 without code changes. * fix(webvoyager): bump curated-30 case timeoutMs 120s → 300s The 120s case timeout was set during the Gen 9 era and dominated the post-cap-fix failure mode (3/4 fails on curated-30 were wall-clock timeouts at 2 min, not capability or budget). Bumping to 5 min closes the timeout surface so capability vs budget vs config can be measured cleanly: cap=300k, timeout=120s: 26/30 = 86.7% (3 timeouts, 0 cost_cap, 1 cap) cap=300k, timeout=300s: 26/30 = 86.7% (0 timeouts, 0 cost_cap, 2 caps, 2 capability/turn-limit) Same headline number; cleaner failure breakdown. The 2 cost_cap fails that surfaced (Amazon, Google Flights at 523k / 1.09M tokens) are runaway loops, not normal operation — bumping the cap further would just burn money. Real fix is loop detection, which runner.ts already has hooks for. Companion file `cases.json` (full 590) is gitignored and regenerates via `webbench:import`; bumping it locally for in-progress full-run validation but the timeout default lives in this curated file.
