The exiftool branch of the date waterfall now pulls raw strings with
group prefixes (one `exiftool -j -q -G1` subprocess per batch, no
`-d %s`) and classifies each candidate:
- zoned strings (own offset / Z) are true instants;
- naive strings from container groups (QuickTime/Track*/Apple) are
UTC-rendered creation_time fields -> true instants (utc_direct).
Running them through the camera wall-clock cascade was the
"videos off by 4-5 hours" bug: it reinterpreted a UTC instant in
the server zone;
- naive strings from photo-EXIF groups are camera wall clocks and run
the offset cascade (OffsetTime* pairing + GPS evidence pulled in
the same exiftool pass).
The legacy date_taken column stays byte-identical to the old
server-local interpretation (reproduced in Rust, DST-aware); the
new-contract date_utc / camera_offset_minutes / date_taken_tz_source
columns carry the true instant.
Manual date edit (POST /image/exif/date) reinterprets the
naive-as-UTC epoch the client sent as a wall clock in the user's
display zone (camera_tz::manual_date_resolution, tz_source =
'manual'), snapshots the pre-override new-contract triple next to the
existing legacy snapshot pair (3 new columns, migration
2026-09-25-000000), and revert restores both pairs.
ADR-0001 records the container-date finding; CLAUDE.md date-pipeline
section updated.
Populate the new-contract date columns at ingest while keeping the
legacy date_taken column byte-identical (ADR-0001):
- camera_tz module: offset cascade (offset tag -> GPS zone -> server
zone) as a pure, testable function; bundled offline TZF geometry for
GPS -> IANA resolution; DST-correct offsets for the capture date;
display-zone helpers (DEFAULT_DISPLAY_TZ, display_zone_for,
display_zone_offset_minutes) for the read-side cutover.
- EXIF branch: kamadak-exif now collects OffsetTime* tags paired with
the winning date tag; resolve_date_taken takes an ExifPrior and
emits (date_utc, camera_offset_minutes, date_taken_tz_source) per
branch: exif -> cascade, exiftool/fs_time -> utc_direct, filename
-> unclassified (pending #116).
- Schema: migration adds image_exif.date_utc /
camera_offset_minutes / date_taken_tz_source and
user_ai_prefs.display_tz (all nullable; down.sql drops them).
- DAO + ingest: backfill_date_taken persists the triple alongside the
legacy pair; watcher, upload, and set_image_gps call sites feed the
cascade.
- Response surface: ExifMetadata and ExifSummary carry the triple so
/image/metadata and /photos/exif expose it (null for unconverted
rows); reel requests mirror display_tz into prefs.
cargo build + clippy clean; 625 lib + 702 bin tests pass (the one
failing doctest in utils.rs is pre-existing at the base commit).
Implement end-to-end nightly pre-generation of memory reels with agentic
scripting that grounds narration in calendar, location, messages, and RAG.
Sections A-E from the plan:
A. Extract produce_reel pipeline core from run_reel_job with
ScripterMode::Fast/Agentic and progress callbacks.
B. Agentic scripter: factor run_readonly_tool_loop from the insight
generator, build read-only tool gate, prompt builder with GPS, and
generate_script_agentic with fallback to fast path.
C. Precomputed reels ledger (SQLite table + DAO), GET /reels/precomputed
handler with validity gate, GET /reels/by-key/{key}/video streaming,
and normalize_library_key helper.
D. Nightly scheduler: spawn_pregen_scheduler with configurable hour,
run_pregen_batch (day/week/month spans), pregen_one with dedup and
disk-check, secs_until_next_run_hour time math.
E. user_ai_prefs passive mirror table + DAO for param capture in
create_reel_handler and replay in the scheduler.
Also fixes resolve_library_param signature to take &[Library] and adds
resolve_library_param_state wrapper for AppState callers.

- Replace impl ToString with impl Display for InsightJobStatus and
InsightGenerationType
- Rename from_str → parse to avoid confusion with std::str::FromStr
- Collapse nested if statements (handlers, insight_chat, insight_generator,
image handlers)
- Use is_multiple_of() instead of manual modulo checks
- Suppress deprecated diesel::dsl::count_distinct (no drop-in replacement
available in current Diesel version)
- Scope MutexGuard in synthesize_merge to drop before await
- Allow dead_code on generate_no_think, enumerate_indexable_files,
total_deleted (intended for future use)
- Allow type_complexity on Diesel query result tuples

New `PhotoSize::XLarge` variant sits between `Large` (2048px) and
`Full` (original). On-demand generated and disk-cached at
`_xlarge/<hash>.jpg`, same waterfall as `Large` (embedded RAW preview
→ ffmpeg → image crate). Sources below 4096px serve at native size.
Reduces decoded bitmap memory from ~192MB (48MP full) to ~64MB for
the mobile viewer's zoom tier.

Adds a third PhotoSize between Thumb (200px) and Full (original). The
viewer placeholder and map callout previously upscaled a 200px thumb
into a full-screen / full-width view, which looked visibly blocky on
3× devices. The new tier is generated on-demand, disk-cached, and
served via the existing /image endpoint.
Storage layout mirrors the Thumb branch's lookup chain:
1. hash-keyed: <thumbs>/_large/<hash[..2]>/<hash>.jpg (shared across
libraries when content_hash is known)
2. library-scoped legacy: <thumbs>/_large/<lib_id>/<rel_path>
Generation pipeline mirrors generate_image_thumbnail:
- RAW: decode the embedded JPEG preview, apply EXIF orientation,
resize to 2048-long-edge, encode JPEG q85
- HEIC/HEIF: ffmpeg with scale + q:v 5 (≈ q85)
- everything else: image crate decode + thumbnail() + JpegEncoder
Never upscales — sources below the 2048 cap re-encode at native size.
Handler offloads decode/resize to web::block to keep the actix worker
free (a 24MP source takes 100–500ms). Writes via tempfile+rename so
concurrent readers can't observe a half-written JPEG. On any
generation failure, falls through to the Full branch (which itself
serves the RAW embedded preview for unrenderable RAW containers).
Video requests for size=large fall back to the existing thumb pipeline
since there's no useful 2048px video tier.

Pure mechanical cleanup of accumulated drift in files outside the
HLS-content-hash branch's main change set. No behavior change.
- `cargo fmt` on every previously-misformatted file
(`ai/insight_generator.rs`, `database/knowledge_dao.rs`,
`faces.rs`, `knowledge.rs`, `libraries.rs`).
- `cargo clippy --fix`:
- `needless_borrow`: `&library` → `library` in `handlers/image.rs`
(two sites in the photo-listing path).
- Manual clippy pass for warnings clippy emits but can't auto-apply:
- `field_reassign_with_default` in `database/reconcile.rs::run` —
consolidated into a struct-literal initializer.
- `needless_range_loop` in `database/knowledge_dao.rs::union_perceptual_tags`
— inner `for b in (a+1)..indices.len() { let ib = indices[b]; ... }`
becomes `for &ib in &indices[a + 1..] { ... }`.
- Doc-list indentation: continuation lines under nested bullets in
`database/mod.rs::get_memories_in_window` and
`database/knowledge_dao.rs::build_entity_graph` realigned to the
list-item content column.
Deliberately not touched (each deserves its own focused commit, with
testing, rather than getting bundled into a sweep):
- 4× `deprecated count_distinct` in `faces.rs` — diesel API migration
to `AggregateExpressionMethods::aggregate_distinct` may shift result
types; needs verification against the existing stats queries.
- `await_holding_lock` in `knowledge.rs:807` — `std::sync::Mutex` held
across `ollama.generate(...).await`. Genuine concurrency bug; fix
requires understanding the surrounding flow before just dropping
the guard.
- 2× `type_complexity` in `database/mod.rs` — cosmetic, would need a
`type` alias and corresponding callers updated.
- Dead `total_deleted` on `library_maintenance::GcStats` and
`file_scan::enumerate_indexable_files` — both are public surface
retained for future use; deletion is a separate decision.
All 707 tests still pass. Release build clean.

main.rs drops from 2935 → 1200 lines, freed for startup wiring +
the watcher. The 16 route handlers move into three domain-grouped
files under src/handlers/:
- handlers/favorites.rs (128 lines): favorites, put_add_favorite,
delete_favorite.
- handlers/video.rs (665 lines): generate_video, stream_video,
get_video_part, get_video_preview, get_preview_status. The 5
pre-existing get_preview_status integration tests move with the
handler (still pass against TestPreviewDao + AppState::test_state).
- handlers/image.rs (1003 lines): get_image (with the
hash/library-scoped/bare-legacy thumb lookup), upload_image,
get_file_metadata, set_image_gps, get_full_exif, set_image_date,
clear_image_date. Helpers (create_circular_thumbnail,
build_metadata_response_for_date_mutation) and request structs
(SetGpsRequest, SetDateRequest, ClearDateRequest, UploadQuery)
travel with them.
main.rs's import block shrinks from ~50 lines to ~22 as everything
HTTP-specific (NamedFile, mp::Multipart, BytesMut, Span, KeyValue,
StreamExt, …) moves with the handlers. The is_video_file wrapper
also goes — remaining callers in watch_files / cleanup use
file_types::is_video_file directly.
cargo test --bin image-api: 325 passing (no regression).
