+# P6b — Playwright + MCP integration spec
+
+**Branch:** `feat/p6b-playwright-e2e`
+**Status:** SHIPPED (this branch)
+**Worktree:** `/root/damascus-orchestrator-p6b`
+**Base:** `main @ acec3ea` (P6a merged)
+
+## Background
+
+PR #20 (`cfcd571`, "Damascus Entry Points P6: E2E verification") already shipped
+the P6b deliverables on `main` — `tests/e2e/test_entry_points_e2e.py` (667
+lines, 4-phase Playwright + MCP test) and `tests/e2e/conftest.py`. The P6b
+kanban card was drafted before the P6 split landed, so the body overlaps with
+P6 instead of complementing it.
+
+P6b's contribution on this branch is therefore **a re-verification** plus a few
+small improvements:
+
+1. **Re-verification against post-PR-#21 main** — the test runs end-to-end
+   against the stack as it exists after the Ask-Hermes UX PR (#21) merged, and
+   it still passes (3 back-to-back clean runs at 29–33s each).
+2. **`DAMASCUS_ROOT` / `DAMASCUS_EVIDENCE_NAME` env vars** — the test now
+   reads these from the environment instead of hardcoding
+   `/root/damascus-orchestrator`. Same file is now reusable from a worktree.
+3. **`tests/e2e/requirements.txt`** — pinned deps for a fresh venv.
+
+## Changes on this branch vs `main`
+
+```
+docs/P6B.md                              | new (this file)
+tests/e2e/requirements.txt                | new (pinned deps)
+tests/e2e/test_entry_points_e2e.py       | 6-line patch: env-var indirection
+```
+
+The patched test runs identically against `main` (where the env vars default
+to the original paths). Run from the worktree with:
+
+```bash
+cd /root/damascus-orchestrator-p6b
+DAMASCUS_ROOT=/root/damascus-orchestrator-p6b DAMASCUS_EVIDENCE_NAME=p6b \
+    python3 -m pytest tests/e2e/test_entry_points_e2e.py -q -s
+```
+

+
+7 screenshots + `pytest.log` prove the test ran green against the live stack
+on 2026-06-26 14:29 UTC. The `.hermes/evidence/` tree is gitignored
+(see `.gitignore` line 46), so evidence is intentionally not committed — it
+regenerates from the test.
+
+## Acceptance criteria
+
+- [x] `pytest tests/e2e/test_entry_points_e2e.py -q -s` exits 0 (last run:
+  `1 passed in 29.35s`).
+- [x] All 7 screenshots present in `.hermes/evidence/p6b/screenshots/`.
+- [x] MCP stdio subprocess communicates cleanly (no init-error logs).
+- [x] Spec uses live stack (api at `127.0.0.1:9110`, MCP launched in stdio
+  against the api container).
+- [x] No browser console errors during Phase 2 / 3.
+
+## PR description (draft)
+
+> **Damascus Entry Points — P6b: Playwright + MCP integration spec**
+>
+> Re-verifies the existing P6 e2e test (`tests/e2e/test_entry_points_e2e.py`,
+> shipped via PR #20) against the post-PR-#21 stack and adds a tiny
+> ergonomic improvement: `DAMASCUS_ROOT` and `DAMASCUS_EVIDENCE_NAME` are
+> now read from the environment so the same test is reusable from a
+> worktree without forking it. Also adds `tests/e2e/requirements.txt`
+> pinning the test deps.
+>
+> Three back-to-back clean runs at ~30s each against the live stack.
+> Evidence (screenshots + pytest.log) regenerated on the worktree at
+> `.hermes/evidence/p6b/` (gitignored by design).
+>
+> Complements P6a (`scripts/verify.sh`, bash recipe) and P6 itself (the
+> test file already on `main`).
+
+## Notes
+
+- The P6b kanban task's body describes the test as "outstanding work" but
+  the file has been on `main` since 2026-06-25 via PR #20. The body was
+  drafted before the P6 split, so this branch documents the overlap and
+  ships the small improvement.
+- CI is intentionally out of scope per the task body. The spec runs locally
+  against a live `docker compose up` stack.
