 <!-- AC:END -->

 ## Implementation Plan

 <!-- SECTION:PLAN:BEGIN -->
-1. Add OpenRouter provider setup through Vercel AI SDK.
-2. Define Zod schemas for internal findings, audit summary, email draft, subject, call script, follow-up, and quality review.
-3. Build model-profile configuration for fast classification, multimodal analysis, and German copy generation.
-4. Combine lead, crawl, screenshot, PageSpeed, and selected skills into prompt inputs.
-5. Persist all prompts, model responses, normalized findings, final texts, and generation errors in Convex.
+1. Worker A: add OpenRouter/Vercel AI SDK dependencies, provider config, model profiles, and schema helpers with RED/GREEN tests.
+2. Worker B: add Convex schema and persistence contracts for structured LLM generations with RED/GREEN source/type tests.
+3. Worker C: add evidence/prompt input builder combining lead, crawl, screenshots, PageSpeed, and local skills with RED/GREEN tests.
+4. Worker D: add Node audit-generation action queue/process flow with screenshots, AI SDK structured outputs, audit/outreach persistence, and failure recording with RED/GREEN tests.
+5. Worker E: add German copy quality guard tests/helpers for Ich-Form, no scores, no prices, no generic KI-Slop, and observation-plus-suggestion style.
+6. Orchestrator: review worker patches, resolve integration gaps through Spark follow-up workers, run full verification, and check acceptance criteria without marking Done.

+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+2026-06-05: Started TASK-11 implementation on branch codex-task-11-openrouter-audit-pipeline using subagent-driven and test-driven workflow. Existing TASK-25 worktree changes were present and will not be reverted or touched unless required.
+
+Wave 1 dispatched with gpt-5.3-codex-spark: Worker A owns AI SDK/OpenRouter dependencies, model profiles, and Zod schemas; Worker B owns Convex auditGenerations schema/persistence; Worker C owns pure audit evidence builder; Worker E owns German customer-copy guard. Orchestrator remains integration/review only and is not hand-coding feature patches.
+
+Implemented Worker-E German copy guard slice in pure deterministic helpers (lib/ai/german-copy-guard.ts) plus TDD tests (tests/german-copy-guard.test.ts). Added issue coverage for language quality, Ich-Form, score/page-speed artifacts, Preise, KI-Slop, anklagende Sprache, technische Artefakte, Beobachtung+Vorschlag. Keinen Fremdscope verändert.
+
+Wave 1 review complete. Spec/code-quality reviewers found expected blocker: auditGenerationAction is not implemented yet and queue currently uses a temporary any reference. Follow-up scope: Worker D will add Node action, typed scheduler reference, screenshot multimodal handoff, AI SDK calls, audit/outreach persistence, and prompt/response size/sanitization guards. Worker F will harden German short-text detection, document model override env vars, and remove generated JS artifacts.
+
+Wave 2 dispatched with gpt-5.3-codex-spark: Worker D owns auditGenerationAction, typed scheduler reference, multimodal screenshot handoff, AI SDK structured stages, audit/outreach persistence, and prompt/response persistence hardening. Worker F owns German short-text guard hardening, OpenRouter override env docs, and removal of generated JS artifacts. Orchestrator remains review/verification only.
+
+Final review before closure: spec reviewer passed all five TASK-11 acceptance criteria, but code-quality reviewer found P1 risks in auditGenerationAction error handling and lead status patching, plus P2 hardening around UTF-8 byte capping/secret redaction. Worker H dispatched with gpt-5.3-codex-spark to address those findings before acceptance criteria are checked.
+
+Implementation complete pending user confirmation. Built OpenRouter/Vercel AI SDK audit-generation pipeline with model profiles, Zod structured outputs, evidence builder, multimodal screenshot handoff, Convex auditGenerations persistence with prompt/response/model metadata, German copy guard, audit/outreach upserts, guarded lead status transition, action-level failure handling, UTF-8 byte-safe truncation, env-secret redaction, and model-profile driven generation parameters. Verification passed: pnpm test (235/235); pnpm exec tsc -p tsconfig.json --pretty false; pnpm lint (0 errors, existing BetterAuth generated warnings only); pnpm exec convex codegen --dry-run --typecheck enable; pnpm build. Final Spark review found no blocking/important issues; residual P3: PageSpeed evidence freshness on re-runs may need future runtime coverage.

+## Final Summary

+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Implemented the OpenRouter/Vercel AI SDK audit-generation pipeline end to end: model profiles, Zod structured outputs, Convex audit generation persistence, evidence builder, multimodal screenshots, German copy guard, audit/outreach draft persistence, guarded lead transition, and hardening for failure handling/secret redaction. Verified with pnpm test, TypeScript, lint, Convex codegen/typecheck, build, and final Spark review.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Website enrichment actions can be killed by Convex with a transient invalid environment error before the JS catch block runs, leaving runs without normal failure finalization or PageSpeed queueing. Add an internal action runtime budget so long browser/bootstrap/crawl work fails inside the action before the platform aborts it.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Website enrichment has an action-level runtime budget below the Convex runtime abort window
+- [x] #2 Long Chromium bootstrap, browser launch, crawl, link checks, and screenshots are bounded by remaining action time
+- [x] #3 When the runtime budget is exceeded, the existing catch path finalizes the enrichment run and queues PageSpeed for the lead
+- [x] #4 Regression tests cover the runtime budget guard and full verification passes
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add RED source regression for action runtime budget and bounded browser/crawl steps
+2. Implement minimal runtime budget helper in websiteEnrichmentAction
+3. Run tests/type/lint and deploy Convex dev
+4. Record findings and leave task open pending manual retest
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+2026-06-05: Investigation found latest website_enrichment run was manually set to failed, but Convex logs show the underlying action ended with "Transient error while executing action" and environment "invalid" before app-level catch/finalization ran. This explains missing finishedAt/errorSummary/PageSpeed follow-up.
+
+2026-06-05: Implemented action-level budget guard (default 120s, TASK8_ACTION_BUDGET_MS override) around Playwright import, Chromium executable resolution, AL2023 library preparation, browser launch/context creation, page crawls, internal link checks, and desktop/mobile screenshots so long work rejects inside the action catch path before Convex invalidates the runtime. Verified with targeted website-enrichment action tests, full pnpm test, TypeScript, lint, and Convex dev typecheck/deploy.

+- [x] #2 outreach_ready patch is guarded by terminal contact status
+- [x] #3 truncateWithMarker is byte-safe and source tests cover byte behavior

+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add source-level regression tests for P1/P2/P3 points
+2. Implement action-level robust failure handling and guarded lead status transition
+3. Fix byte-aware truncation and shared sanitization paths in action/persistence
+4. Rework model-profile driven generation config and multimodal gating
+5. Add deterministic outreach upsert behavior and run full checks
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Verified as TASK-11 final hardening follow-up. Fixed action-level catch/failure finish, terminal-status guard for outreach_ready, UTF-8 byte-safe truncation, env-backed secret redaction, model-profile params/supportsImages usage, and deterministic outreach upsert for explicit empty values. Verification passed with TASK-11 final checks; task remains In Progress pending user confirmation.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Shipped final audit-generation hardening: catch-all post-start failure handling, terminal lead-status guard, byte-safe truncation, env-backed secret redaction, model-profile driven parameters/supportsImages, and deterministic outreach upsert behavior. Verified together with TASK-11 final checks.
