Address the PR #202 review (approve-with-comments). The only actionable
non-blocking item was the test-coverage suggestion: the source switch in
AiChatService.handle from findRecent(chatId, ws, 50) to findAllByChat(chatId,
ws) was not pinned by a test. handle() is a streaming method the project marks
as not unit-testable, so cover the behavioral guarantee it now relies on at the
repo/integration level — seed a chat of 60 messages and assert the default
findAllByChat (exactly how handle calls it) returns the FULL transcript in
chronological order, including the first turn the old 50-window would have
dropped.
Also document the behavior change under CHANGELOG [Unreleased] -> Changed.
The two stability items (token-budget trim before streamText; O(N) history
rebuild per turn) are deferred: the reviewer flagged both as non-blocking
conscious trade-offs aligned with the PR's stated goal, and the trim is a
larger architecture change out of scope for this follow-up.

The per-turn model conversation was rebuilt via findRecent(chatId, ws, 50),
a sliding window that dropped the beginning of any chat longer than ~50 stored
rows. Switch streamChat to the existing findAllByChat, which loads the full
non-deleted transcript chronologically with a 5000-row memory-safety backstop
(keeps the newest rows + logs a warning on overflow) — a safety net, not a
conversational limit. Remove the now-unused findRecent method and update the
comments/log text that referenced it (findAllByChat now feeds both the Markdown
export and the model history).
