"""Phase 50 E2E (Playwright): save & view chat history.
TODO.md L5 (owner 2026-08-29): "Need a way to save and view chat
history in a new page, then return to that history with a click"
Run in isolation (DB must be up: ``podman compose up -d db``):
uv run pytest tests/e2e/test_chat_history.py -v --no-cov
The owner-locked loop under test (A10 extension, 2026-08-29):
* **Save** — on the chat page, admin-only (the pill ships hidden and
whoami reveals it): the current conversation POSTs to ``/api/chats``
(auto-title = the first question, whitespace-collapsed, 120-char cap)
and links to the created row; a re-Save PUTs the SAME row (upsert);
"New chat" unlinks, so the next Save creates again;
* **History** — ``/history.html`` lists the saved chats in a full-width
table (Title | Messages | Updated | Actions); the Title cell IS the
Open link (``/?chat=<id>`` — "return to that history with a click"),
and Delete is the inline two-step confirm (owner-locked: no native
confirm dialog — a real ``window.confirm`` would hang Playwright, so
the inline pair appearing is itself pinned);
* **Open** — ``/?chat=<id>`` (valid uuid + admin) boots into the saved
conversation through the SAME restore path as the phase-14 local
session (pixel-identical), links it, and a subsequent Save updates
that row; a deleted/unknown id degrades to the local restore with the
error banner;
* **Anonymous** — no Save button, no History nav link, the History page
shows the gated state WITHOUT ever fetching ``/api/chats`` (the router
403s them — pinned via the request log), and the API 403s.
DB isolation: the shared e2e Postgres keeps ``saved_chats`` rows across
suites, so every test here uses a DISTINCTIVE question text (its
auto-title is therefore unique), never asserts on absolute row counts,
and deletes the rows it creates in a ``finally`` (admin cookie). The KB
tables are truncated + re-seeded the house way (deterministic mock
embeddings); ``saved_chats`` is never touched by the reset.
