+## Current CI reporter-time <10 stabilization + trend summary pass (2026-04-18)
+
+- Worktree: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability`
+- Branch: `codex/web-ci-panel-observability-8s`
+- Goal in this pass:
+  - move required web Playwright lane from the current `~10.2s` watch edge to a safer `<10s` zone by reducing worker tail.
+  - persist and surface **trend comparison** directly in Actions summary (not just one-run snapshots).
+- Changes in this pass:
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/web/e2e/ordinary-user-ci.spec.ts`
+    - `openApp()` now supports `includeRoutingPanel` option.
+    - only one generation lane blocks on routing panel readiness; other lanes measure core shell bootstrap to reduce duplicated panel wait cost and tail latency.
+    - route-entry test still asserts “模型路由观测” visibility to preserve UX/state coverage.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/.github/workflows/ci.yml`
+    - bumped `WEB_PLAYWRIGHT_WORKERS` from `3` to `4` in required `Web test (required)`.
+    - added lightweight trend-cache lifecycle:
+      - restore `web-playwright-trend-*` cache before web test,
+      - pass `WEB_PLAYWRIGHT_TREND_FILE=/tmp/web-ci-trend/playwright-trend.json`,
+      - save trend cache after run.
+    - trend cache scope uses `${{ github.head_ref || github.ref_name }}` so pull_request merge refs reuse branch trend history.
+    - adds timing row for trend-cache restore into the existing CI step duration table.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/web/scripts/run-playwright-ci.mjs`
+    - added trend-state read/write (JSON) support for reporter/app-bootstrap metrics.
+    - computes and publishes trend rows in `$GITHUB_STEP_SUMMARY`:
+      - reporter vs previous run delta,
+      - reporter rolling average,
+      - reporter trend status (under target or watch),
+      - app-bootstrap max vs previous run delta,
+      - app-bootstrap rolling average,
+      - tracked run count.
+- Verification in this pass:
+  - `npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/web test` with CI env + `WEB_PLAYWRIGHT_WORKERS=4` ✅
+    - real Playwright browser run: `4 passed (2.8s)` then repeat `4 passed (3.0s)`.

+## Current high-yield minimal upgrade package (2026-04-18)
+
+- Worktree: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability`
+- Branch: `codex/web-ci-perf-8s-stability`
+- Scope completed in this pass:
+  1. Routing strategy layering by `taskType + contentFormat`.
+  2. Health-probe-driven provider fallback (cooldown skip).
+  3. Observability instrumentation + dashboard/report template.
+- API routing changes:
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/src/common/openrouter.service.ts`
+    - `RoutedChatOptions` now supports `contentFormat: tweet|thread|article|diagram|generic`.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/src/common/model-gateway.service.ts`
+    - candidate pool now factors both `taskType` and `contentFormat`.
+    - low-latency tweet lanes prefer floor models earlier; depth-critical lanes (article/diagram/package) keep high-tier priority.
+    - provider health state tracks recent success/failure samples and cooldown windows.
+    - cooldown providers are skipped when alternatives exist; if all candidates are cooling down, original pool is retained to avoid deadlock.
+    - request-level observability events are appended as NDJSON when `MODEL_GATEWAY_OBSERVABILITY_ENABLED=1`.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/src/common/codex-local.service.ts`
+    - local Codex prompt now carries `contentFormat` hint.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/src/modules/generate/generate.service.ts`
+    - all major `chatWithRouting` callsites now pass `contentFormat` (and `diagram` hint when visual mode is diagram).
+- Regression coverage:
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/test/model-gateway.test.ts`
+    - added tests for format-aware layering and health fallback behavior.
+- Observability/reporting deliverables:
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/scripts/model-routing-dashboard-report.ts`
+    - reads NDJSON routing events and outputs markdown dashboard.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/docs/observability/MODEL-ROUTING-DASHBOARD-TEMPLATE.md`
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/output/reports/observability/MODEL-ROUTING-DASHBOARD-2026-04-18_14-48-28.md` (sample generated report)
+  - root `package.json`: new command `pnpm report:model-routing`.

+
+## Current phase-2 integration (usage/ops observability surfaced in /app) (2026-04-18)
+
+- Worktree: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability`
+- Branch: `codex/web-ci-perf-8s-stability`
+- Goal in this pass: continue “第2阶段” by exposing model-routing health and fallback hotspots in the ordinary-user `/app` flow without breaking local-default pass criteria.
+- Architecture choice in this pass:
+  - Chosen: **reuse existing `/usage/summary` contract** and enrich it with routing-health metadata from `ModelGatewayService`; then render in `/app`.
+  - Not chosen: add a new `/v3/ops` endpoint. Reason: higher contract/migration cost for little user value; `/usage/summary` already powers ops/usage lane and is guarded by auth/workspace context.
+  - Rollback path: remove `/app` usage-summary fetch + panel; existing generation flow remains unchanged.
+- Backend/API lane changes:
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/src/common/model-gateway.service.ts`
+    - added `getRoutingHealthSnapshot()` public accessor.
+    - returns profile + health-probe config + per-provider health summary for ops/usage consumption.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/src/modules/usage/usage.service.ts`
+    - injects `ModelGatewayService`.
+    - exports `buildRoutingFallbackHotspots(...)`.
+    - `summary()` now enriches `modelRouting` with:
+      - `profile`
+      - `healthProbe`
+      - `providerHealth`
+      - `fallbackHotspots`
+    - keeps existing `fallbackRate/avgQualityScore` fields for guidance compatibility.
+  - API semantics unchanged:
+    - route still `GET /usage/summary` under AuthGuard.
+    - permissions and workspace scoping unchanged (`WorkspaceContextService` default workspace resolution).
+    - error envelope remains existing app-level behavior.
+- Regression coverage added/updated:
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/test/usage-routing-observability.test.ts`
+    - validates fallback-hotspot sorting/limit behavior.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/test/model-gateway.test.ts`
+    - validates health snapshot shape for ops/usage panels.
+- Front-end/UX lane changes:
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/web/lib/queries.ts`
+    - adds `fetchUsageSummary()` and typed `UsageSummaryResponse`.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/web/components/v3/operator-app.tsx`
+    - `/app` now loads usage summary as a non-blocking dependency.
+    - adds “模型路由观测” panel:
+      - counters (`totalCalls`, `fallbackRate`, `avgQualityScore`)
+      - provider health probe cards (healthy/cooling-down state)
+      - fallback hotspot list (lane + rate + hit count)
+    - if usage data fails, panel degrades gracefully and does not block generation.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/web/e2e/ordinary-user-ci.spec.ts`
+    - CI mock now serves `/usage/summary`.
+    - adds regression assertion that `/app` renders “模型路由观测”.
+- Verification run in this pass:
+  - `npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/api test -- test/model-gateway.test.ts test/usage-routing-observability.test.ts` ✅ (`244/244`)

+## Current CI performance branch for routing-panel timing observability (2026-04-18)
+
+- Worktree: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability`
+- Branch: `codex/web-ci-panel-observability-8s`
+- Base commit: `4ab70d0` (`feat: surface routing health and fallback hotspots in app`)
+- Goal in this pass:
+  - keep `pnpm --filter @draftorbit/web test` in the required lane stable.
+  - add explicit CI timing visibility for the new `/app` routing-observability panel request path (`/usage/summary`) without changing product behavior.
+- Changes in this pass:
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/web/e2e/ordinary-user-ci.spec.ts`
+    - `openApp()` now emits:
+      - `[ci-perf] app bootstrap (includes /usage/summary panel) completed in <Xs>`
+    - this captures user-visible `/app` bootstrap timing including the new panel readiness.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/web/scripts/run-playwright-ci.mjs`
+    - parses app-bootstrap timing markers from Playwright output.
+    - parses generation-scenario timings and computes count/avg/slowest.
+    - appends these metrics into `$GITHUB_STEP_SUMMARY`:
+      - app bootstrap target/avg/max/status
+      - generation scenario count/avg/slowest
+    - adds `WEB_PLAYWRIGHT_APP_BOOTSTRAP_TARGET_SECONDS` (default `2.5`) as non-blocking watch metric.
+  - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/.github/workflows/ci.yml`
+    - sets `WEB_PLAYWRIGHT_APP_BOOTSTRAP_TARGET_SECONDS: '2.5'` in the required `Web test (required)` job.
+- Performance/verification evidence in this pass:
+  - `npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/web test` ✅
+    - node tests: `23/23`
+    - Playwright: `4 passed (6.0s)` (reporter), harness `6.43s`
+    - app bootstrap markers from logs:
+      - `0.37s`, `0.29s`, `0.32s` (includes `/usage/summary` panel)
+    - generation markers still present for scenario-level hotspot tracking.
+  - `npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/web typecheck` ✅
+  - `NEXT_PUBLIC_API_URL=http://127.0.0.1:4311 npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/web build` ✅
+
+## Current built-in browser UAT-driven iteration pass (2026-04-18)
+
+- Worktree: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability`
+- Branch: `codex/web-ci-perf-8s-stability`
+- Goal in this pass: execute a fresh ordinary-user full-flow acceptance from `/` to `/app` and route gates (`/queue` `/connect` `/pricing`), re-verify X-login entry, and directly fix blockers before local commit (no push).
+- Key runtime used:
+  - API `http://127.0.0.1:4311` with `X_CALLBACK_URL=http://127.0.0.1:3300/auth/callback`, `AUTH_MODE=self_host_no_login`.
+  - Web `http://127.0.0.1:3300` using `next build` + `next start` for stable UAT.
+  - `vendor/baoyu-skills` restored/pinned to `9977ff520c49ea0888d8d43d582973c6e8c1d55a` by `node scripts/ensure-baoyu-skills-runtime.mjs`.
+- Blocker found and fixed in this pass:
+  - Ordinary-user case `diagram-process-prompt` failed closed because tweet quality gate hard-failed `missing_scene` even for explicit diagram-intent prompts.
+  - Fix:
+    - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/src/modules/generate/content-quality-gate.ts`
+      - add diagram-intent detection from `visualPlan` + text/focus cues.
+      - keep tweet scene guard for normal tweet flows, but clear `missing_scene` when diagram intent is explicit.
+    - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/apps/api/test/content-quality-gate.test.ts`
+      - add regression test `buildContentQualityGate allows diagram-intent tweet prompts without missing_scene hard fail`.
+- Browser/UAT evidence captured:
+  - Full ordinary-user sync rerun passed: `7/7` cases.
+    - tracked report: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/output/reports/uat-full/BAOYU-ORDINARY-USER-SYNC-2026-04-18_06-48-53.md`
+    - artifact root: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/output/playwright/ordinary-user-baoyu-sync-2026-04-18_06-48-53/`
+  - Real browser route/CTA pass from `/` to `/app` plus queue/connect/pricing gates:
+    - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/output/playwright/local-full-flow-2026-04-18-14-07-46/full-flow-report.json`
+  - X login entry verification after callback env wiring:
+    - `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/output/playwright/x-login-uat-result-2026-04-18-14-07-09.json`

+    - result: no `Missing required env: X_CALLBACK_URL`; redirect reaches `https://x.com/i/oauth2/authorize...`.
+- Verification commands run in this pass:
+  - `npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/web typecheck` ✅
+  - `npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/web test` ✅ (`23` node tests + `4` Playwright tests, reporter `3.0s`)
+  - `NEXT_PUBLIC_API_URL=http://127.0.0.1:4311 npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/web build` ✅

+  - `npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/api test` ✅ (`237/237`)
+- Safety guard remains unchanged:
+  - no real X post execution;
+  - no real payment execution;
+  - external-key absence continues to fail closed or mark evidence as local-only.
+
+
+## Current Playwright reporter-time stabilization pass (2026-04-17)
+
+- Worktree: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability`
+- Branch: `codex/web-ci-perf-8s-stability`
+- Base: `origin/main` at `90fb21816e7b3df9ce628fbcea390c699729f88f`.
+- Goal: stabilize web Playwright reporter time around the 8s lane with lower run-to-run variance while preserving the required-check contract.
+- Scenario optimization:
+  - `apps/web/e2e/ordinary-user-ci.spec.ts` now keeps the app open per generation-group test and reuses the same page/session across scenarios instead of reopening `/app` every scenario.
+  - Generation scenarios are split into two grouped tests (`tweet/thread` and `article/diagram`) to reduce per-step churn and improve CI worker scheduling.
+  - Retry-only visual recovery + latest-source fail-closed assertions now run in one continuous app session test instead of two separate reopen flows.
+  - Connect/queue/pricing safe-gate checks are folded into the home→app entry test to remove an extra test lifecycle while keeping route coverage.
+  - Mobile CTA test keeps hover/focus/overflow assertions but removes always-on screenshot capture in CI runs to cut avoidable I/O latency.
+  - Added per-scenario timing logs (`[ci-perf] generation scenario ...`) for direct hotspot inspection in Actions logs.
+- CI observability upgrade:
+  - `.github/workflows/ci.yml` now writes a persistent `CI step duration table` into `$GITHUB_STEP_SUMMARY`.
+  - Web Playwright workers are tuned to `3` in CI to improve parallel scheduling while staying below the prior contention seen at higher worker counts.
+  - The table includes wall time + note for `Restore Playwright Chromium cache`, `Install Playwright Chromium`, `Web test (required)`, `Web build`, and cache save behavior.
+  - Added explicit restore/save timing rows (including skipped-on-cache-hit visibility) so long-tail cache behavior is observable across runs.
+

+- baoyu runtime comparison uses real runnable artifacts where available: source capture, markdown normalization, visual prompt/spec files, local SVG assets and baoyu-imagine provider seams.
+- baoyu does not expose a direct tweet/thread/article writer CLI in this pinned runtime; writer quality is judged against the baoyu fixed/adversarial rubric without faking direct baoyu text output.
+- `draftorbit/heuristic`, `openrouter/free`, `ollama/*`, placeholder images and mock images invalidate test_high evidence; `codex-local/*` counts only when explicitly enabled by `CODEX_LOCAL_ALLOW_QUALITY_EVIDENCE=1`.
+
+## Evidence notes
+
+- No real OPENAI_API_KEY/OPENROUTER_API_KEY was available; this run allows Codex OAuth local adapter evidence only because CODEX_LOCAL_ALLOW_QUALITY_EVIDENCE=1 and the adapter smoke must pass.
+- No live search provider was configured; ambiguous latest-fact prompts are expected to fail closed unless the user supplies a URL.

+## Product-relevant baoyu matrix
+
+| baoyu skill | status | DraftOrbit usage | test evidence | gap / remaining reason | repair result |
+| --- | --- | --- | --- | --- | --- |
+| `baoyu-url-to-markdown` | `runtime_integrated` | Clear user-provided URLs are captured as markdown sourceArtifacts before latest/source-required article generation. | `latest-hermes-agent-url-source` requires a ready `sourceArtifacts[].markdownPath` and rejects source-free latest-fact output. | No remaining product gap for explicit URL capture in the ordinary-user UAT scope. | Pinned runtime to audited upstream main and keeps source-ready assertions in the UAT script. |
+| `baoyu-danger-x-to-markdown` | `runtime_integrated` | X/Twitter source URLs are routed through the baoyu source-capture runtime when the user supplies social-source evidence. | Source cases assert fail-closed behavior unless a captured markdown artifact is present; dangerous login/posting actions are not invoked. | Only capture/export is in scope; no reverse-engineered login flow is allowed in DraftOrbit. | Documented as safe source capture only, with latest/source ambiguity blocked for ordinary users. |
+| `baoyu-format-markdown` | `rubric_or_prompt_reference` | Article readability and markdown hygiene are enforced through DraftOrbit result gates and ordinary-user copy assertions. | Article cases reject generic scaffold output, title repetition, method-framework title tone and prompt-wrapper leaks. | Not exposed as a separate user action; used as formatting/rubric parity rather than a standalone CLI button. | Report marks this as rubric parity, not falsely as a direct DraftOrbit runtime call. |
+| `baoyu-imagine` | `runtime_integrated` | Visual plans produce prompt files and app-rendered SVG artifacts with baoyu runtime provenance while avoiding placeholder/mock images. | Tweet/thread/article cases require ready visualAssets, promptPath, template-svg renderer, app-rendered textLayer and no prompt leaks. | External image-provider keys may be absent locally; UAT treats mock/placeholder artifacts as failures for quality evidence. | Pinned runtime and ordinary-user UAT keep the provider/mock distinction explicit. |
+| `baoyu-image-gen` | `rubric_or_prompt_reference` | Deprecated upstream alias is migrated to the `baoyu-imagine` provider seam; DraftOrbit does not call it as an active runtime entry. | Runtime smoke and UAT reports mark `baoyu-image-gen` as deprecated and require `baoyu-imagine` for actual visual generation. | `baoyu-image-gen` is deprecated/migrated to `baoyu-imagine`, so direct invocation would be stale product behavior. | Documented as deprecated alias only; active visual runtime uses `baoyu-imagine` plus local SVG rendering. |
+| `baoyu-image-cards` | `rubric_or_prompt_reference` | Thread generation must produce a ready `cards` asset and responsive gallery evidence for ordinary users. | `thread-product-update` rejects runs missing a ready cards asset or leaking card number labels into visual cues. | The upstream skill is prompt/reference-oriented in this pin, so DraftOrbit validates card deliverables rather than calling a CLI. | Kept a hard UAT assertion for thread cards. |
+| `baoyu-cover-image` | `rubric_or_prompt_reference` | Tweet and article outputs require cover-style visual artifacts with visible ordinary-user gallery state. | Visual UAT requires ready cover assets for article cases and visible “主视觉方向/图文资产” UI copy. | No separate cover-image CLI is invoked from DraftOrbit in this recovery pass. | Report identifies the gap as intentional product-surface consolidation. |
+| `baoyu-infographic` | `rubric_or_prompt_reference` | Article outputs require a summary visual asset: infographic or illustration. | Article cases reject runs without a ready cover plus infographic/illustration asset. | No separate infographic CLI is invoked from the current ordinary-user UI. | Kept artifact-level assertion instead of adding an unplanned feature. |
+| `baoyu-article-illustrator` | `rubric_or_prompt_reference` | Article result previews require a section visual path through illustration or infographic assets. | Article UAT accepts ready illustration/infographic evidence and rejects missing summary/section visuals. | Upstream exposes batch helper scripts, but DraftOrbit keeps article illustration behind its restored visual pipeline. | Documented as parity-through-artifact instead of direct CLI execution. |
+| `baoyu-diagram` | `runtime_integrated` | Diagram intent and explicit diagram mode produce a standalone process/flow SVG asset with local renderer provenance. | Diagram prompts and visualRequest.mode=`diagram` are expected to produce a ready `diagram` asset with SVG metadata and quality-gate coverage. | Raster diagram providers remain optional; default pass uses safe local SVG diagrams rather than external services. | Added diagram to visual planning, renderer, parity matrix and ordinary-user UAT scope. |
+| `baoyu-compress-image` | `safe_gap` | Current DraftOrbit can download generated assets but does not promise a separate compression workflow. | UAT checks “下载全部图文资产” state and leaves large image/provider artifacts local-only. | Compression is a future delivery hardening gap, not a restored active UI feature. | Kept out of runtime; report flags it for a future safe delivery pass. |
+| `baoyu-markdown-to-html` | `runtime_integrated` | Article and export-enabled runs create Markdown and HTML files in the local artifact bundle with download links. | Article visualRequest.exportHtml requires markdown/html export assets and a signed bundle URL in the result preview. | No real CMS publish is performed; HTML is a local safe export package for manual reuse. | Integrated safe Markdown→HTML export artifacts into the visual pipeline and report matrix. |
+| `baoyu-post-to-x` | `blocked_external_action` | DraftOrbit only prepares/queues/manual-confirms publish state; real X posting is blocked unless a safe explicit integration exists. | Tweet/thread UAT requires “连接 X 后才能发布” visibility and never executes a real post. | Real external posting and reverse-engineered login flows are intentionally out of scope for this local audit. | Kept as sandbox/manual publish-prep only and documented in the report matrix. |

+# DraftOrbit × baoyu ordinary-user sync comparison (2026-04-20_04-17-31)
+
+- API: `http://127.0.0.1:4311`
+- Web: `http://127.0.0.1:3300`
+- Evidence root: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability/output/playwright/ordinary-user-baoyu-sync-2026-04-20_04-17-31`
+- baoyu-skills commit: `9977ff520c49`
+- Cases: `7`
+- Pass count: `7/7`
+
+## Comparison policy
+
+- DraftOrbit is tested through the ordinary `/` → `/app` user path, not only direct API calls.
+- baoyu runtime comparison uses real runnable artifacts where available: source capture, markdown normalization, visual prompt/spec files, local SVG assets and baoyu-imagine provider seams.
+- baoyu does not expose a direct tweet/thread/article writer CLI in this pinned runtime; writer quality is judged against the baoyu fixed/adversarial rubric without faking direct baoyu text output.
+- `draftorbit/heuristic`, `openrouter/free`, `ollama/*`, placeholder images and mock images invalidate test_high evidence; `codex-local/*` counts only when explicitly enabled by `CODEX_LOCAL_ALLOW_QUALITY_EVIDENCE=1`.
+
+## Evidence notes
+
+- No real OPENAI_API_KEY/OPENROUTER_API_KEY was available; this run allows Codex OAuth local adapter evidence only because CODEX_LOCAL_ALLOW_QUALITY_EVIDENCE=1 and the adapter smoke must pass.
+- No live search provider was configured; ambiguous latest-fact prompts are expected to fail closed unless the user supplies a URL.

+## Product-relevant baoyu matrix
+
+| baoyu skill | status | DraftOrbit usage | test evidence | gap / remaining reason | repair result |
+| --- | --- | --- | --- | --- | --- |
+| `baoyu-url-to-markdown` | `runtime_integrated` | Clear user-provided URLs are captured as markdown sourceArtifacts before latest/source-required article generation. | `latest-hermes-agent-url-source` requires a ready `sourceArtifacts[].markdownPath` and rejects source-free latest-fact output. | No remaining product gap for explicit URL capture in the ordinary-user UAT scope. | Pinned runtime to audited upstream main and keeps source-ready assertions in the UAT script. |
+| `baoyu-danger-x-to-markdown` | `runtime_integrated` | X/Twitter source URLs are routed through the baoyu source-capture runtime when the user supplies social-source evidence. | Source cases assert fail-closed behavior unless a captured markdown artifact is present; dangerous login/posting actions are not invoked. | Only capture/export is in scope; no reverse-engineered login flow is allowed in DraftOrbit. | Documented as safe source capture only, with latest/source ambiguity blocked for ordinary users. |
+| `baoyu-format-markdown` | `rubric_or_prompt_reference` | Article readability and markdown hygiene are enforced through DraftOrbit result gates and ordinary-user copy assertions. | Article cases reject generic scaffold output, title repetition, method-framework title tone and prompt-wrapper leaks. | Not exposed as a separate user action; used as formatting/rubric parity rather than a standalone CLI button. | Report marks this as rubric parity, not falsely as a direct DraftOrbit runtime call. |
+| `baoyu-imagine` | `runtime_integrated` | Visual plans produce prompt files and app-rendered SVG artifacts with baoyu runtime provenance while avoiding placeholder/mock images. | Tweet/thread/article cases require ready visualAssets, promptPath, template-svg renderer, app-rendered textLayer and no prompt leaks. | External image-provider keys may be absent locally; UAT treats mock/placeholder artifacts as failures for quality evidence. | Pinned runtime and ordinary-user UAT keep the provider/mock distinction explicit. |
+| `baoyu-image-gen` | `rubric_or_prompt_reference` | Deprecated upstream alias is migrated to the `baoyu-imagine` provider seam; DraftOrbit does not call it as an active runtime entry. | Runtime smoke and UAT reports mark `baoyu-image-gen` as deprecated and require `baoyu-imagine` for actual visual generation. | `baoyu-image-gen` is deprecated/migrated to `baoyu-imagine`, so direct invocation would be stale product behavior. | Documented as deprecated alias only; active visual runtime uses `baoyu-imagine` plus local SVG rendering. |
+| `baoyu-image-cards` | `rubric_or_prompt_reference` | Thread generation must produce a ready `cards` asset and responsive gallery evidence for ordinary users. | `thread-product-update` rejects runs missing a ready cards asset or leaking card number labels into visual cues. | The upstream skill is prompt/reference-oriented in this pin, so DraftOrbit validates card deliverables rather than calling a CLI. | Kept a hard UAT assertion for thread cards. |
+| `baoyu-cover-image` | `rubric_or_prompt_reference` | Tweet and article outputs require cover-style visual artifacts with visible ordinary-user gallery state. | Visual UAT requires ready cover assets for article cases and visible “主视觉方向/图文资产” UI copy. | No separate cover-image CLI is invoked from DraftOrbit in this recovery pass. | Report identifies the gap as intentional product-surface consolidation. |
+| `baoyu-infographic` | `rubric_or_prompt_reference` | Article outputs require a summary visual asset: infographic or illustration. | Article cases reject runs without a ready cover plus infographic/illustration asset. | No separate infographic CLI is invoked from the current ordinary-user UI. | Kept artifact-level assertion instead of adding an unplanned feature. |
+| `baoyu-article-illustrator` | `rubric_or_prompt_reference` | Article result previews require a section visual path through illustration or infographic assets. | Article UAT accepts ready illustration/infographic evidence and rejects missing summary/section visuals. | Upstream exposes batch helper scripts, but DraftOrbit keeps article illustration behind its restored visual pipeline. | Documented as parity-through-artifact instead of direct CLI execution. |
+| `baoyu-diagram` | `runtime_integrated` | Diagram intent and explicit diagram mode produce a standalone process/flow SVG asset with local renderer provenance. | Diagram prompts and visualRequest.mode=`diagram` are expected to produce a ready `diagram` asset with SVG metadata and quality-gate coverage. | Raster diagram providers remain optional; default pass uses safe local SVG diagrams rather than external services. | Added diagram to visual planning, renderer, parity matrix and ordinary-user UAT scope. |
+| `baoyu-compress-image` | `safe_gap` | Current DraftOrbit can download generated assets but does not promise a separate compression workflow. | UAT checks “下载全部图文资产” state and leaves large image/provider artifacts local-only. | Compression is a future delivery hardening gap, not a restored active UI feature. | Kept out of runtime; report flags it for a future safe delivery pass. |
+| `baoyu-markdown-to-html` | `runtime_integrated` | Article and export-enabled runs create Markdown and HTML files in the local artifact bundle with download links. | Article visualRequest.exportHtml requires markdown/html export assets and a signed bundle URL in the result preview. | No real CMS publish is performed; HTML is a local safe export package for manual reuse. | Integrated safe Markdown→HTML export artifacts into the visual pipeline and report matrix. |
+| `baoyu-post-to-x` | `blocked_external_action` | DraftOrbit only prepares/queues/manual-confirms publish state; real X posting is blocked unless a safe explicit integration exists. | Tweet/thread UAT requires “连接 X 后才能发布” visibility and never executes a real post. | Real external posting and reverse-engineered login flows are intentionally out of scope for this local audit. | Kept as sandbox/manual publish-prep only and documented in the report matrix. |

+## Session 2026-04-17 03:56:24 PDT — built-in browser + local core flow
+
+### Scope
+- Entry from `/` via **本机快速体验**.
+- Core user paths: generation, export evidence, queue, connect, pricing.
+- Environment: local Web `http://127.0.0.1:3300`, local API `http://127.0.0.1:4311`.
+
+### Step-by-step verification
+
+| Step | Action | Result | Evidence |
+| --- | --- | --- | --- |
+| 1 | Home page keyboard focus to **本机快速体验** and press Enter | ✅ Entered `/app` successfully | Built-in browser snapshot `uid=4_0`, URL `http://127.0.0.1:3300/app`, loader copy `正在加载生成器` |
+| 2 | In `/app`, input minimal prompt and start generation | ✅ Generation pipeline started and progressed | Snapshot shows `runId: 74433cc4...`, stage text advanced through `正在生成草稿` → `正在匹配你的文风` → `正在准备可发布结果` |
+| 3 | Open queue path `/queue?intent=confirm_publish` | ✅ Redirected to `/app?nextAction=confirm_publish` and displayed review gate | Snapshot `uid=17_0`: heading `确认这条内容是否发出`, visible `当前待确认内容`, button `确认发布` |
+| 4 | Open connect path `/connect?intent=connect_x_self` | ✅ Redirected to `/app?nextAction=connect_x_self` and displayed safe connect gate | Snapshot `uid=18_0`: heading `连接 X 账号后再发布会更顺`, button `连接 X 账号` |
+| 5 | Open `/pricing` | ✅ Pricing and billing plans loaded | Snapshot `uid=19_0` + network `GET /v3/billing/plans [200]` |
+| 6 | Export flow evidence (automation supplement) | ✅ Export-related core scenario passed | `pnpm --filter @draftorbit/web test` passed; includes scenario `app generation covers article and diagram visual outputs...` with assertions for `导出 HTML` and bundle/export actions |
+
+### Additional notes
+- Home page X-login path still surfaces environment issue when using X auth CTA:
+  - UI message: `Missing required env: X_CALLBACK_URL`
+  - Network evidence seen in prior home-page check: `GET /auth/x/authorize [500]`
+- This does **not** block local ordinary-user path via **本机快速体验** and `/app` core flow.
+
+### Automated command evidence captured in this session
+
+```bash
+npm_config_cache=/tmp/draftorbit-npm-cache npx pnpm@10.23.0 --filter @draftorbit/web test
+```
+
+Observed result:
+- `4 passed (5.3s)`
+- `Web Playwright CI harness finished in 5.87s`
+- Contains generation + export + queue/connect/pricing coverage in `apps/web/e2e/ordinary-user-ci.spec.ts`.
+
+
+
+## Session 2026-04-17 04:15:46 PDT — X_CALLBACK_URL configured + X 登录入口 UAT (live local)
+
+### Scope
+- Validate X login entry after explicitly providing `X_CALLBACK_URL`.
+- Keep local-first environment and avoid real post/payment actions.
+
+### Runtime configuration used
+- API launch env (local):
+  - `PORT=4311`
+  - `APP_URL=http://127.0.0.1:3300`
+  - `AUTH_MODE=self_host_no_login`
+  - `DATABASE_URL=postgresql://draftorbit:draftorbit@localhost:5433/draftorbit`
+  - `REDIS_URL=redis://localhost:6379`
+  - `JWT_SECRET=dev-local-secret`
+  - `X_CLIENT_ID=local-ci-x-client`
+  - `X_CLIENT_SECRET=local-ci-x-secret`
+  - `X_CALLBACK_URL=http://127.0.0.1:3300/auth/callback`
+- Web launch mode for stable UAT:
+  - `next build` then `next start --hostname 127.0.0.1 --port 3300`
+  - `NEXT_PUBLIC_API_URL=http://127.0.0.1:4311`
+  - `NEXT_PUBLIC_ENABLE_LOCAL_LOGIN=true`
+
+### X 登录入口结果
+
+| Step | Action | Result | Evidence |
+| --- | --- | --- | --- |
+| 1 | API contract probe `GET /auth/x/authorize?intent=connect_x_self` | ✅ 200 JSON returned, no env-missing failure | Response body includes authorize URL with `redirect_uri=http%3A%2F%2F127.0.0.1%3A3300%2Fauth%2Fcallback`; requestId observed |
+| 2 | Real browser UAT: open `/`, click **用 X 登录开始** | ✅ Request succeeded and browser navigated to X OAuth authorize page | `/tmp/x-login-uat-result.json`: `requestStatus: 200`, `requestUrl: http://127.0.0.1:4311/auth/x/authorize`, `finalPageUrl: https://x.com/i/oauth2/authorize...` |
+| 3 | Regression check for previous failure copy | ✅ No `Missing required env: X_CALLBACK_URL` shown | `/tmp/x-login-uat-result.json`: `missingEnvVisible: false` |
+| 4 | Visual evidence | ✅ Screenshot captured during OAuth entry flow | `output/playwright/x-login-entry-uat-2026-04-17.png` (ignored artifact) |
+
+### Notes
+- This pass validates **X 登录入口可拉起** and callback wiring presence in authorize URL.
+- Real X account authorization completion is intentionally out of scope in local safety policy.
+
+## Session 2026-04-18 07:08 PDT — built-in browser full-flow rerun + diagram gate fix
+
+### Scope
+- Worktree: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability`
+- Objective: rerun ordinary-user full flow (`/` → `/app` → generation/export → `/queue`/`/connect`/`/pricing`) and verify X 登录入口 after `X_CALLBACK_URL` wiring, then directly fix blockers.
+- Runtime: API `http://127.0.0.1:4311` (with `X_CALLBACK_URL=http://127.0.0.1:3300/auth/callback`), Web `http://127.0.0.1:3300` (`next build` + `next start`).
+
+### Blocker found and direct fix
+
+| Item | Problem | Direct fix | Regression evidence |
+| --- | --- | --- | --- |
+| Diagram tweet intent in ordinary-user flow | `diagram-process-prompt` was blocked by `missing_scene` quality hard-fail, causing diagram visual asset generation to fail closed even when user explicitly requested a process diagram. | Updated `apps/api/src/modules/generate/content-quality-gate.ts`: detect diagram intent from `visualPlan`/focus/text cues and skip `missing_scene` hard-fail for tweet diagram intent. | Added test in `apps/api/test/content-quality-gate.test.ts`: `buildContentQualityGate allows diagram-intent tweet prompts without missing_scene hard fail`; API suite now passes with this regression covered. |
+
+### Built-in browser / visual verification results
+
+| Step | Action | Result | Evidence |
+| --- | --- | --- | --- |
+| 1 | Click **用 X 登录开始** on `/` | ✅ redirected to X OAuth authorize entry with callback present | `output/playwright/x-login-uat-result-2026-04-18-14-07-09.json` (`finalUrl` is `https://x.com/i/oauth2/authorize...redirect_uri=http%3A%2F%2F127.0.0.1%3A3300%2Fauth%2Fcallback`), screenshot `output/playwright/x-login-entry-uat-2026-04-18-14-07-09.png` |
+| 2 | Browser full-path check from `/` to `/app`, then `/queue` `/connect` `/pricing` | ✅ route entry/redirect/CTA visibility verified | `output/playwright/local-full-flow-2026-04-18-14-07-46/full-flow-report.json` and step screenshots `01-home.png`…`06-pricing.png` |
+| 3 | Ordinary-user full UAT matrix rerun (tweet/thread/article/diagram/URL source/latest fail-closed + route audit + export actions) | ✅ all pass (`7/7` cases, route audit `5/5`) | `output/reports/uat-full/BAOYU-ORDINARY-USER-SYNC-2026-04-18_06-48-53.md`, artifact root `output/playwright/ordinary-user-baoyu-sync-2026-04-18_06-48-53/` |
+
+### Notes
+- This pass keeps safety boundaries unchanged: no real post to X, no real payment execution, no dangerous login automation.
+- X 登录入口 verification only checks **authorize entry availability + callback wiring + no env-missing error**.
+
+## Session 2026-04-18 08:20 PDT — minimal API live smoke (/health + protected route)
+
+### Scope
+- Goal: 增加最小后端 live smoke，闭环验证“健康检查 + 鉴权保护路由”。
+- Environment: local API `http://127.0.0.1:4311`.
+- Policy: read-only smoke only; no schema/data migration; no publish/payment side effects.
+
+### API contract / permissions expectations (pre-check)
+- `GET /health`:
+  - Contract: public health endpoint, returns service liveness/readiness and dependency status.
+- `GET /usage/summary`:
+  - Contract: protected usage summary endpoint (requires `Authorization: Bearer <token>`).
+  - Permission semantics: missing token should return `401 UNAUTHORIZED`; valid token should return `200` workspace-scoped summary.
+
+### Step-by-step live smoke
+
+| Step | Command | Expected | Observed | Result |
+| --- | --- | --- | --- | --- |
+| 1 | `curl -i http://127.0.0.1:4311/health` | 200 + health payload | `HTTP/1.1 200 OK`; body: `{\"ok\":true,\"service\":\"draftorbit-api\",\"live\":true,\"ready\":true,\"dependencies\":{\"db\":true,\"redis\":true}}` | ✅ |
+| 2 | `curl -i http://127.0.0.1:4311/usage/summary` | 401 unauthorized when no token | `HTTP/1.1 401 Unauthorized`; body includes `{\"code\":\"UNAUTHORIZED\",\"message\":\"缺少 Authorization Header\"}` | ✅ |
+| 3 | `curl -X POST /auth/local/session` then `curl -i -H \"Authorization: Bearer <token>\" /usage/summary` | 200 with usage summary | `HTTP/1.1 200 OK`; body includes `workspaceId`, `counters`, `modelRouting` (including `profile`, `healthProbe`, `providerHealth`, `fallbackHotspots`) | ✅ |
+
+### Backend lane evidence summary
+- **API contract:** unchanged; smoke validated existing `/health` + `/usage/summary` behavior.
+- **Error semantics:** unauthorized request returns `401` + `UNAUTHORIZED` envelope (as designed).
+- **Permissions:** protected route correctly blocks missing header and allows valid Bearer token.
+- **Data consistency:** this smoke is read-only for business surfaces (`/health`, `/usage/summary`); only local session issuance used for auth bootstrap.
+- **Observability impact:** request ids observed in each response (`x-request-id`), and usage summary includes routing observability fields.
+
+## Session 2026-04-18 08:23 PDT — frontend visual evidence refresh (docs-only closure)
+
+### Scope
+- Purpose: add one fresh real-browser visual pass to close this audit chain together with the API smoke above.
+- No UI code changes; evidence-only run.
+
+### Visual verification (real browser)
+
+| Item | Check | Result | Evidence |
+| --- | --- | --- | --- |
+| Page load default state | Open `http://127.0.0.1:3300/`, verify title and initial render | ✅ pass | `title=DraftOrbit — 一句话生成可发的 X 内容` |
+| Responsive breakpoints | Capture 375 / 768 / 1024 / 1440 screenshots | ✅ pass | `375.png`, `768.png`, `1024.png`, `1440.png` |
+| Runtime/browser errors | Verify browser error log file | ✅ pass | `errors.txt` is empty |
+
+Artifact root:
+- `/var/folders/vp/w2775f6n3ts10l3gmfvk_p180000gn/T/draftorbit-ui-review.iFgXs3`
+
+State-coverage note:
+- This docs-only pass validates **default render + responsive visual integrity + error-free runtime**.
+- Hover/focus-visible/active/loading/disabled/success interactive state checks were not the target in this closure pass because no UI behavior changed.
+
+## Session 2026-04-20 04:17 PDT — ordinary-user full-flow rerun + API smoke same-session closure
+
+### Scope

+  - `/queue` / `/connect` / `/pricing` route gates
+  - include tweet / thread / article / diagram / URL-source / latest fail-closed paths.
+- In the same pass, append backend/API smoke evidence (`/health` + protected `/usage/summary`) to close frontend/backend audit loop in one session.

+- `GET /health` should stay public and return readiness/dependency status.
+- `GET /usage/summary` should require Bearer token:
+  - no token → `401 UNAUTHORIZED`
+  - valid token → `200` workspace-scoped usage summary.
+
+| Step | Command | Expected | Observed | Result |
+| --- | --- | --- | --- | --- |
+| 1 | `curl http://127.0.0.1:4311/health` | `200` + health payload | `200`; `{\"ok\":true,\"service\":\"draftorbit-api\",\"live\":true,\"ready\":true,\"dependencies\":{\"db\":true,\"redis\":true}}` | ✅ |
+| 2 | `curl http://127.0.0.1:4311/usage/summary` | `401` unauthorized | `401`; `{\"code\":\"UNAUTHORIZED\",\"message\":\"缺少 Authorization Header\"...}` | ✅ |
+| 3 | `POST /auth/local/session` then `GET /usage/summary` with `Authorization: Bearer <token>` | `200` summary | `200`; payload includes `workspaceId`, `counters`, `modelRouting.profile=local_quality`, provider-health and fallback-hotspot aggregates | ✅ |
+
+### Backend lane closure notes
+- **API contract:** unchanged; this pass validates existing endpoints only.
+- **Error semantics:** unauthorized access returns `401` with `UNAUTHORIZED` envelope and requestId.
+- **Permissions:** protected route blocks missing auth and allows valid local session token.
+- **Data consistency:** read-only smoke on summary/health surfaces; no publish/payment side effects executed.
+- **Observability:** summary payload includes routing observability fields (`profile`, health/hotspot aggregates), matching current UI ops panel expectations.

+## Session 2026-04-20 07:08 PDT — full ordinary-user rerun (`/` → `/app` → generation/export/queue/connect/pricing) + same-session API smoke
+
+### Scope
+- User-requested full ordinary-user rerun in the already opened local environment.
+- Journey covered in one pass:
+  - `/` landing entry
+  - `/app` generation flows: tweet / thread / article / diagram / URL-source / latest fail-closed
+  - export actions: markdown/html/bundle download + retry gate
+  - route gates: `/queue?intent=confirm_publish`, `/connect?intent=connect_x_self`, `/pricing`
+- Same-session backend closure: `GET /health` + protected `GET /usage/summary` unauthorized/authorized checks.
+
+### Runtime and recovery actions (same session)
+- Worktree: `/Users/yangshu/.config/superpowers/worktrees/002-draftorbit.io/web-ci-perf-8s-stability`
+- API: `http://127.0.0.1:4311`
+- Web: `http://127.0.0.1:3300`
+- Routing flags for this rerun:
+  - `MODEL_ROUTING_PROFILE=local_quality`
+  - `MODEL_ROUTER_ENABLE_CODEX_LOCAL=1`
+  - `CODEX_LOCAL_ADAPTER_ENABLED=1`
+  - `CODEX_LOCAL_ALLOW_QUALITY_EVIDENCE=1`
+- baoyu runtime pin:
+  - `node scripts/ensure-baoyu-skills-runtime.mjs`
+  - commit: `9977ff520c49ea0888d8d43d582973c6e8c1d55a`
+- Iteration during rerun:
+  - First attempt hit Prisma pool exhaustion due multiple stale `@draftorbit/api dev` watchers from other worktrees.
+  - Cleaned stale API dev stacks and reran with a single API instance in this worktree + `local_quality` profile.
+  - Final rerun passed with full matrix `7/7`.

+
+### Backend/API smoke (same session)
+
+Contract and permission expectations:
+- `GET /health`: public health endpoint; expect `200` + readiness payload.
+- `GET /usage/summary`: protected endpoint; expect `401` when missing token, `200` when authorized.
+
+| Step | Command | Expected | Observed | Result |
+| --- | --- | --- | --- | --- |
+| 1 | `curl /health` | `200` | `200`, `{"ok":true,"live":true,"ready":true,"dependencies":{"db":true,"redis":true}}` | ✅ |
+| 2 | `curl /usage/summary` (no token) | `401` unauthorized | `401`, `{"code":"UNAUTHORIZED","message":"缺少 Authorization Header"...}` | ✅ |
+| 3 | `POST /auth/local/session` then bearer `GET /usage/summary` | `200` summary | `200`, payload includes `workspaceId`, `counters`, `modelRouting` | ✅ |
+
+### Closure notes
+- This pass completed frontend route/state evidence and backend permission semantics in one continuous local session.
+- No real X posting, no real payment execution, and no dangerous login automation were performed.
+
+## Session 2026-04-20 07:22 PDT — realtime home-page screenshot evidence supplement
