2026-06-02	feat: persist per-tab token/cache usage across reload	Adam Malczewski
	Persist usage as invisible type:"usage" chunk rows (side channel): - core: add "usage" ChunkType + UsageData; exclude usage rows from getChunksForTab/getTotalChunkCount; add getUsageStatsForTab aggregate (exported from barrel); defensive skip in groupRowsToMessages. - api: agent-manager accumulates per-attempt usageRows and flushes them in the same atomic appendChunks call as the turn's content (discarded on a superseded fallback attempt). GET /tabs enriches rows with usageStats. - frontend: hydrateFromBackend seeds cacheStats from usageStats (reload only; no re-seed on statuses reconnect, so no double-count with live events). Tests: core DB-backed usage persistence/aggregate; api usage-row-per-event + fallback discard; routes GET /tabs usageStats; frontend hydrate seed + no-double-count + live-accumulation-after-seed. 495 -> 509 passing.
2026-05-30	refactor(chunks): append-only chunk log with per-step cache-stable wire	Adam Malczewski
	Replace the message-as-container model with a flat, append-only chunk log. - chunks table (id, tab_id, seq, turn_id, step, role, type, data_json): one row per chunk; tool_call (assistant) and tool_result (tool) are SEPARATE rows linked by callId. Message/turn are derived groupings, not stored. - chunks/transform.ts: DB-free explode (Chunk[] -> rows) / group (rows -> messages), shared by backend and the browser frontend. - Cache fix: toModelMessages segments each turn at tool-batch boundaries into stable [assistant, tool] pairs per step, so earlier steps serialize byte-identically across requests (kills the prompt-cache churn). - agent-manager persists a turn's chunks on seal (once), discarding a failed fallback attempt's partial chunks; rebuilds agent history from the log. - GET /messages windows the log by chunk seq then groups; loadMoreMessages merges a turn split across the window boundary by turnId. - One-shot migration drops the legacy messages table and clears tabs; settings/credentials/keys/usage preserved. Full suite green (317 tests); biome, tsc, and svelte-check clean.
