Append mode: applied ephemerally — original system message restored
before persistence so re-opens see the baked persona. Amend mode:
override stays in place and becomes the new insight row's system
message. Pattern mirrors annotate_system_with_budget.
Adds system_prompt field on both ChatTurnHttpRequest and ChatTurnRequest;
plumbs through chat_turn and chat_turn_stream identically.

Branch B of the multi-library data-model rollout. tagged_photo and
photo_insights now follow the bytes (content_hash), not the path,
matching the policy pinned in CLAUDE.md "Multi-library data model".
Branch A's availability probe and EXIF scoping land first; this
branch builds on top.
Migration (2026-05-01-000000_hash_keyed_derived_data)
Adds nullable content_hash columns to tagged_photo and photo_insights,
with partial indexes on the non-null subset to keep the index small
during the transitional window. The migration backfills from
image_exif:
* tagged_photo joins on rel_path alone (no library_id available);
* photo_insights joins on (library_id, rel_path), unambiguous.
Rows whose image_exif hash isn't known yet stay null and the runtime
reconciliation pass populates them as the hash backlog drains.
Insert-time population
TagDao::tag_file looks up image_exif.content_hash by rel_path before
inserting; the hash is written into the new column.
InsightDao::store_insight does the same scoped to (library_id,
rel_path). Caller-supplied hash on InsertPhotoInsight wins; otherwise
the DAO does the lookup. Both paths fall back to None if the hash
isn't known yet — reconciliation backfills.
Reconciliation (database/reconcile.rs)
Three idempotent passes the watcher runs once per tick after the
per-library backfill loop:
1. tagged_photo NULL hashes → populate from image_exif by rel_path.
2. photo_insights NULL hashes → populate by (library_id, rel_path).
3. photo_insights scalar merge — when multiple is_current rows
share a content_hash, keep the earliest generated_at as
current; demote the rest. Demoted rows keep their data so
/insights/history is unaffected; only the "current" pointer
narrows to one per hash.
No filesystem dependency, so reconcile doesn't need the availability
gate; runs every tick. Logs once when something changed, debug
otherwise.
Tags are set-valued under the policy (union on read, already
DISTINCT in queries), so there is no analogous tag-collapse pass —
duplicate (tag_id, content_hash) rows across libraries are
harmless.
Read paths are unchanged in this branch — lookup_tags_batch's
existing rel_path-via-hash-sibling expansion still produces the
correct merge. A follow-up can simplify reads to use the new column
directly for performance.
Tests: 217 pass (212 pre-existing + 5 new in reconcile covering
NULL-fill, hash-not-yet-known no-op, library scoping on insights,
earliest-wins collapse, idempotency).

Optional integration with the sibling Apollo project's user-defined
Places (name + lat/lon + radius_m + description + category). When
APOLLO_API_BASE_URL is set, the per-photo location resolver folds the
most-specific containing Place into the LLM prompt's location string —
"Home (My house in Cambridge) — near Cambridge, MA" rather than the
city name alone. Smallest-radius wins; Apollo sorts server-side via
/api/places/contains, so the carousel badge in Apollo and the prompt
string here always agree.
Adds an agentic tool `get_personal_place_at(latitude, longitude)` that
the LLM can call during chat continuation. Tool description tells the
model the call returns the user's free-text notes, not just a name.
Deliberately narrow — no enumerate-all variant, lat/lon required.
Unset APOLLO_API_BASE_URL = legacy Nominatim-only path, tool is not
registered. 5 s timeout; all errors degrade silently.
Tests: 5 unit tests for compose_location_string (Apollo only, Nominatim
only, both, both-with-description, neither).

The mobile client's regenerate-after-failure flow sends a discard index
equal to the server's rendered count (its optimistic user bubble for the
failed turn was never persisted). find_raw_cut treated this as out of
range, surfacing as "Chat rewind failed: discard_from_rendered_index out
of range" and blocking the retry.

- Few-shot injection on /insights/generate/agentic: compresses prior
training_messages into trajectory blocks (tool calls + result summaries)
and injects into the system prompt. Hardcoded default ids with optional
request override.
- New fewshot_source_ids column on photo_insights (+ migration) to track
which exemplars influenced a given row, for downstream training-set
filtering. Chat amend rows stamp None with a lineage note.
- Ollama client now remembers which server (primary/fallback) most
recently succeeded and tries it first on the next call, via a shared
Arc<AtomicBool>. Avoids re-404ing the primary on every agent iteration
when the chosen model only lives on the fallback.
- Demote noisy logs: daily_summary "Summary match" lines to debug;
inner chat_with_tools non-2xx body log from error to warn (outer
layer owns the terminal-error signal).
- Drift-guard tests for summarize_tool_result covering the success /
empty / error / unknown shape for every tool.
- Tidy: three pre-existing clippy warnings cleaned up.

- Inject the max-iterations budget into the agentic system prompt for
both insight generation and chat turns. Chat does this per-turn by
appending a note to the replayed system message and restoring it
before persistence so the note doesn't accumulate across turns.
- Stop deleting entity_photo_links at the start of agentic insight
generation. The clear made recall_facts_for_photo always return
empty, wasting a tool call and discarding knowledge from prior runs.
Re-linking the same entity is already an INSERT OR IGNORE no-op.

Add LlmClient::chat_with_tools_stream and SSE endpoint
POST /insights/chat/stream that emits text deltas, tool_call /
tool_result pairs, truncated notice, and a terminal done frame as the
agentic loop runs.
- Ollama: parses NDJSON from /api/chat stream, accumulates content
deltas, emits Done with tool_calls from the final chunk.
- OpenRouter: parses OpenAI-compatible SSE, reassembles tool_call
argument deltas by index, asks for stream_options.include_usage.
- InsightChatService spawns the loop on a tokio task, feeds events
through an mpsc channel, persists training_messages at the end.

load_history now groups preceding tool_call + tool_result scaffolding
under each assistant reply as `tools: [{name, arguments, result}]`.
Result bodies over 2000 chars are truncated for payload size with a
`result_truncated` flag; the full value remains in training_messages.

Rewind: POST /insights/chat/rewind truncates training_messages at a
given rendered index, dropping the target message plus any preceding
tool-call scaffolding. The initial user prompt is protected.
Metrics: log prompt_eval_count/duration and eval_count/duration from
every Ollama chat response, rendered as tokens + ms + tok/s.

Adds POST /insights/chat and GET /insights/chat/history. Replays the
stored agentic conversation through the same backend the insight was
generated with (or a per-turn override), runs a short tool-calling
loop, and persists the extended history in append or amend mode.
Backend switching: same-backend or hybrid->local replay verbatim;
local->hybrid is rejected in v1 (would require on-the-fly vision
description rewrite).
Per-(library, file) async mutex serialises concurrent turns. Soft
context budget drops oldest tool_call+result pairs when the
serialized history exceeds num_ctx - 2048 tokens.
