"""saved_chats: owner-saved chat conversations
|
|
|
|
Revision ID: 0008
|
|
Revises: 0007
|
|
Create Date: 2026-08-29
|
|
|
|
Phase 50 (save-and-view-chat-history story, A13 — one additive,
|
|
reversible table, no other schema change):
|
|
|
|
* ``saved_chats`` — one row per conversation the owner explicitly
|
|
Saves (the A10 extension, owner permission 2026-08-29):
|
|
``/api/chat`` stays stateless and nothing is stored about a
|
|
conversation that was not saved. ``title`` (the API-side auto-title —
|
|
first question) is plain String(500) so a future rename needs no
|
|
migration; ``messages`` is JSONB holding the exact ``bor.chat.v1``
|
|
localStorage record shape (phase 14) so a saved chat restores
|
|
pixel-identical through the existing ``renderStoredMessage`` path;
|
|
``created_at``/``updated_at`` are stamped server-side (``updated_at``
|
|
additionally bumps on every row update via the ORM ``onupdate``).
|
|
No share-related columns — phase 51 adds ``share_token`` in ``0009``.
