Upload only the consumed feed files; uniform nupkg names

release.py no longer uploads the legacy RELEASES and assets.*.json
manifests — the in-app updater reads only releases.<channel>.json plus
the nupkg it references. The Windows feed nupkg gains its -win channel
marker (vpk omits it for the legacy default channel), so all platforms
are uniformly mediahive-{ver}-{channel}-full.nupkg. The -full suffix is
Velopack's asset type and stays.

+
+## Python 3.14 syntax: unparenthesized `except` is valid
+
+This project targets Python **>= 3.14** (see `requires-python` in
+`pyproject.toml`). Per [PEP 758](https://peps.python.org/pep-0758/) (Final,
+Python 3.14), multiple exception types may be caught **without parentheses**:
+
+```python
+except OSError, ValueError:   # valid Python 3.14+, equivalent to except (OSError, ValueError):
+```
+
+Parentheses are still required when an `as` clause is used:
+`except (OSError, ValueError) as e:`.
+
+Do not "fix" these into tuple form, and do not flag them as Python 2 remnant
+syntax errors — that rule is obsolete training data. Any syntax validation,
+compilation check, or linting of this codebase must run under Python 3.14+
+(e.g. `python -m py_compile` with a 3.14 interpreter); older interpreters
+will report false SyntaxErrors on this and other 3.14-only constructs.

-# Multi-Root Implementation Notes
-
-## Overview
-
-MediaHive now supports multiple independent media roots. Each root is a filesystem directory with its own index, scanner, and WebSocket stream. The frontend merges per-root state into a single reactive view.
-
-## Architecture
-
-### Root Identity
-
-- **Root ID**: friendly root name derived from configured path basename.
-- **Name/ID collision handling**: suffixes `2`, `3`, … are appended to keep each root ID unique.
-- **Path normalization**: lower-case Windows drive letter, strip trailing slashes, forward slashes only (`as_posix()`).
-
-### Per-Root Runtime (`RootContext`)
-
-Each active root gets an isolated `RootContext` managed by the `Supervisor`:
-
-- `root_id`, `root_path` — stable identifiers
-- `IndexStore` — owns snapshot at `<root>/.mediahive/index.json`
-- `RootScanner` — per-root scanning instance (replaced legacy global scanner)
-- `asyncio.Queue` + consumer task — bridges scanner events to WebSocket
-- `status`: `idle` | `loading` | `ready` | `scanning` | `error`
-
-### Supervisor
-
-- Holds `dict[str, RootContext]` keyed by `root_id`.
-- `replace_roots(new_roots)` atomically swaps the active set:
-  1. Validate & canonicalize paths.
-  2. Derive unique friendly `root_id` for each.
-  3. Prepare new `RootContext`s (load snapshots).
-  4. Swap dict atomically.
-  5. Stop removed contexts in background with bounded timeout.
-- Exposes merged read helpers (`merged_index`, `all_statuses`).
-
-### Item IDs
-
-`root_id` is stored separately on each item.
-
-- `Movie.id` uses a slug built from the movie title and year, for example `spider-man-no-way-home-2021`.
-- `Series.id` uses a slug built from the series title, for example `lost`.
-- Legacy snapshot migrations are handled by `scripts/indexmigr.py`, not during app startup.
-
-## API
-
-| Endpoint | Description |
-|----------|-------------|
-| `GET /api/roots` | List all roots (name, path, root_id, status) |
-| `PUT /api/roots` | Atomically replace full root map `{name: path}` |
-| `WS /api/ws/{root_id}` | Per-root WebSocket (init/upsert/remove/task + status/task events) |
-| `GET /api/media/{root_id}/{path:path}` | Serve media file scoped to root |
-| `GET /api/assets/{root_id}/{asset_type}/{asset_path:path}` | Serve `.mediahive/{asset_type}` assets (`movies`, `series`, `people`) |
-| `POST /api/play/{root_id}` | Play file within root |
-| `POST /api/open-folder/{root_id}` | Open folder within root |
-| `GET /api/meta/{root_id}/{meta_key}` | Per-root metadata (for example `playback-state`) |
-| `POST /api/ui/pick-folder` | Native OS folder picker (returns path) |
-
-> **Removed legacy endpoints**: `/api/change-folder`, `/api/index`, `/api/scan`, `/api/status`, `/api/playback/resume-positions`. No backwards compatibility is maintained.
-
-## macOS Startup Safety
-
-The server **must not** touch the filesystem during startup, because macOS may show permission dialogs that block the event loop and prevent the HTTP server from accepting requests.
-
-- `lifespan()` creates a background task (`_activate_all_roots()`) and immediately yields.
-- All filesystem validation (`exists()`, `is_dir()`, `resolve()`) runs in a thread pool via `asyncio.to_thread()`.
-- CLI entry points (`__main__.py`, `winmain.py`, `hivescan/__main__.py`) pass raw paths via the `MEDIAHIVE_ROOTS` environment variable; they do **not** validate paths before starting the server.
-
-## POSIX Path Enforcement
-
-All stored and transmitted paths use forward slashes exclusively:
-
-- `_normalize_path()` always returns POSIX paths.
-- Config stores `p.as_posix()`.
-- URLs use `/` separators.
-- `Path(root_path) / relative_path` works correctly on Windows because `Path` accepts POSIX separators.
-
-## Config Migration
-
-- Old `media_folder` string is auto-migrated to `roots: {basename: path}` on load.
-- `roots` is persisted back to TOML config.
-
-## Scanner
-
-- Legacy global module-level scanner API was removed from `hivescan/scanner.py`.
-- `RootScanner` is the only scanning interface.
-- Each `RootScanner` owns its own `showreel_queue`, `scan_task`, `rescan_worker_task`, and `_seen_mtimes`.
-
-## Frontend
-
-- `useMediaWebSocket.ts` manages one WebSocket per active root.
-- `App.vue` merges per-root `movieMap`/`seriesMap` into a single `mediaIndex`.
-- `Header.vue` provides add/remove root UI via `PUT /api/roots`.
-- Playback URLs are root-qualified (`/api/media/{root_id}/...`).
-- Metadata cache assets use typed root paths (`/api/assets/{root_id}/{asset_type}/...`) rather than exposing `.mediahive` in URLs.

+# Scanner review — findings, fixes, and measured results
+
+Date: 2026-09-03 (review); fixes implemented same day.
+Scope: `mediahive/hivescan/*`, `mediahive/index_store.py`, `mediahive/root_registry.py`,
+`mediahive/models/events.py`
+Method: code review plus instrumented runs of the real `RootScanner` (monkeypatched
+timers around every ffmpeg invocation, HTTP request, and filesystem primitive).
+
+Structure of this document:
+
+- **Section 1** records the findings as measured against the *pre-fix* code
+  (line references are from that revision).
+- **Section 2** describes the fixes that were implemented for each finding.
+- **Section 3** gives before/after measurements.
+- **Appendix A** (blob storage options) is kept for reference only; it was
+  explicitly decided **not** to change the on-disk storage format for now.
+
+Test environment (details omitted intentionally): the media library lives on a
+network-mounted filesystem (SMB/CIFS). Two roots were measured:
+
+- **Subset root**: 163 torrents (121 movies, 40 series entries), stale/empty index.
+- **Full library root**: existing index with 1127 movies, 159 series,
+  1608 episodes, ~2983 video files, ~35k people records.
+
+Environment characteristic that dominates several measurements:
+`stat`/`scandir`/`exists` on the network mount are ~0.1 ms (attribute caching
+works), but **every small file write costs ~0.2 s** (synchronous write-through).
+The scanner writes thousands of small files into `.mediahive/` on that mount.
+
+---
+
+## 1. Findings (pre-fix)
+
+### F1 — Partial rescan replaces whole entries (the "disappearing seasons" bug)
+
+**This is a correctness bug, not a performance issue.**
+
+Chain of events:
+
+1. Discovery mtime-gates per torrent directory/file. Touching one season
+   directory of a series yields a `downloads` list containing *only that
+   season*.
+2. `_process_series` rebuilds the `Series` object from only the items it was
+   given.
+3. `IndexStore.upsert_series` **replaced the entire entry** and broadcast the
+   partial series to all connected clients.
+
+Measured end-to-end on a 5-season series (5 separate season torrents,
+110 episodes):
+
+```
+full scan        -> index entry seasons [1,2,3,4,5] (110 episodes)
+touch season 4   -> rescan 0.2 s, emits ONE upsert: seasons [4] (22 episodes)
+                 -> index entry is now seasons [4] — seasons 1-3,5 gone
+```
+
+The missing seasons returned only when a scan happened to include all seasons
+again — in practice the next **process restart**, because the seen-mtimes map
+(F2) was memory-only and forced a full rediscovery at startup.
+
+Same bug class, other variants:
+
+- **Movies**: a touched version directory dropped the other versions of the
+  same movie from the listing.
+- **TMDb dedupe collapse**: when a partial entry arrived under a *different*
+  item id for an already-known TMDb id, the old **complete** entry was
+  explicitly deleted.
+- **Deletions were never detected**: discovery only ever added to
+  `_seen_mtimes`; nothing emitted removals. A torrent deleted from disk stayed
+  in the index forever.
+
+### F2 — No persistent scan state: every restart was a full reprocess
+
+All scanner state was process memory: `_seen_mtimes`, the ffmpeg probe cache,
+and the episode/playable-file/bluray-probe caches.
+
+Consequences measured:
+
+- **Steady-state rescan within one process: 0.2 s** (subset root, nothing
+  changed) — mtime gating worked fine while the process lived.
+- **Warm-restart scan (fresh process caches, all disk caches warm): 56.5 s**
+  for the same 163 items, of which **52.9 s (94 %) was re-running ffmpeg probes
+  on all 469 video files** (21 s `ffmpeg -i` + 32 s `showinfo` passes on HDR
+  files). TMDb was 100 % disk-cache hits and cost 0.8 s total.
+- Scaled to the full library: every application restart re-probed **~2983
+  files ≈ 6–8 minutes** of sequential ffmpeg, during which the whole index was
+  re-derived and re-upserted item by item (see F4).
+
+### F3 — Preview (showreel) generation: restart storms and infinite retries
+
+- **Every scan that included an item enqueued all of its reel tasks**, whether
+  or not the reels existed. Existence was only checked later by the serial
+  worker. A full scan of the subset root enqueued **467** tasks; the full
+  library would enqueue ~2700.
+- **Nothing was persisted about the queue.** A restart before the queue drained
+  started everything over.
+- **Failures were never recorded.** In the drain test, 3 of 18 movies failed
+  deterministically (DoVi profile 7 titles require `libplacebo` tonemapping,
+  which fails on GPU-less machines; one file has a matroska demux error). The
+  same files were retried on every subsequent drain — ~1.5 s of probing plus
+  crop detection plus an error task broadcast to every client, **forever**.
+- The reel-existence check required **all five** reels; short videos
+  legitimately produce fewer, so they were treated as "missing" and re-queued
+  on every scan, generating nothing new each time.
+- Measured generation pace with software AV1 encoding: ~16–28 s per movie
+  (5 clips), ~4–5 s per episode clip.
+- The reel worker rebroadcast **whole items** built from stale scan data,
+  clobbering newer store state.
+
+### F4 — Degraded operation while a full scan is in progress
+
+- Items were re-upserted one by one as processed; combined with F1, any
+  partial rescan interleaved with normal use made listings lose data until the
+  next restart.
+- The showreel worker broadcast an **error task for every permanent failure on
+  every scan** (F3), producing user-visible noise.
+- The index snapshot was rewritten every 5 s while dirty; with 1286+ items
+  that is a ~7.5 MB serialize + write per flush, continuously, for the
+  duration of a scan.
+- `upsert_*` rebuilt the TMDb-id lookup maps on **every** upsert — O(n²) per
+  scan. Measured negligible; fixed anyway as part of the merge work.
+
+### F5 — Cold-scan cost was serialized small-file I/O, not TMDb
+
+Cold scan of the subset root: **975 s for 163 items**.
+
+| Time | Share | Where |
+|---|---|---|
+| 763 s | 78 % | `download_cast_profile`: 3494 cast images, strictly serialized; ≈0.22 s each ≈ 0.19 s network-mount write + 0.03 s HTTP |
+| ~100 s | 10 % | ffmpeg probes (469 files, incl. 83 HDR `showinfo` passes) |
+| 73 s | 7 % | TMDb API layer: 217 uncached requests (27 s HTTP) **plus ~41 s writing per-request cache JSON files** to the network mount |
+| ~75 s | 8 % | covers / backdrops / season posters (same small-write cost) |
+| 0.3 s | — | filesystem discovery walk |
+
+Notes:
+
+- The TMDb disk cache itself is fine: once warm it serves 282 requests in
+  0.8 s. Cache *reads* need no optimization.
+- The full cast of every title was downloaded sequentially, one tiny file per
+  person (the full library has ~35k people records). Re-runs are cheap
+  (exists-check), so this was a cold-scan-only cost — but it made the first
+  scan of a new root take ~8× longer than everything else combined.
+
+### F6 — Measured as noise (not worth effort)
+
+- The 30-second rescan loop's tree walk: 3.5–6 s per pass over the full
+  library (~1900 directories). Continuous but light.
+- `get_directory_size` per torrent: 0.1 s total in the scan.
+- TMDb disk-cache reads: sub-second per scan.
+- `trigger_scan` was dead code — nothing called it.
+- `_seen_mtimes` was updated *before* processing; a cancelled/failed scan
+  permanently lost that update until the next restart.
+- The in-process probe cache was keyed by path only; a replaced file kept
+  stale probe data until restart.
+
+---
+
+## 2. Implemented fixes
+
+All proposals P1–P5 from the review were implemented, keeping the existing
+on-disk format unchanged (no blob storage — see Appendix A).
+
+### F1 → merge-semantics upserts + deletion sync
+
+- The `Upsert` event now carries `scanned: list[str]` — the media-root-relative
+  torrent paths whose content was (re)scanned to build the item
+  (`mediahive/models/events.py`; `_process_movies`/`_process_series` yield it).
+- `IndexStore.upsert_movie/upsert_series` (`mediahive/index_store.py`) merge a
+  partial rebuild into the existing entry instead of replacing it:
+  file entries belonging to scanned torrents are replaced, everything else is
+  preserved, episodes/seasons emptied by the merge are dropped, same-episode
+  multi-release files are unioned, and non-None scalar fields from the fresh
+  scan win. The store broadcasts only when the merged result actually changed.
+- The TMDb dedupe collapse now folds duplicates through the same merge (the
+  complete entry's scalars win), so a partial candidate can no longer delete a
+  complete entry; the reverse TMDb-id map is fixed up incrementally instead of
+  rebuilding both maps per upsert (also F4/P5).
+- **Deletion sync**: discovery collects the full set of candidate torrent
+  paths; after a fully completed scan the scanner emits a new `Sync` event and
+  `IndexStore.sync_torrent_paths` drops file entries whose torrent path is
+  gone, cascading to empty episodes/seasons/items with proper removals.
+
+### F2 → persisted scan state and probe cache
+
+Three small JSON files under `.mediahive/` per root, loaded at scanner start
+and written atomically (tmp + rename) **only when changed**:
+
+- `scan-state.json`: relpath → mtime. A restart over an unchanged library now
+  discovers "0 new items" and finishes in walk time. Mtimes are committed
+  **after** the scan completes successfully (fixes the pre-commit nit from F6):
+  a cancelled/failed scan retries its items.
+- `probe-cache.json`: path → {mtime, size, probe fields} for every probed
+  file, **failures included**. Keying by mtime+size makes it self-invalidating
+  when a file is replaced (also fixes the stale-probe nit from F6). Non-plain
+  paths (bluray:/concat: URIs) fail `stat` and stay memory-cached only.
+- `reel-state.json`: see F3 below.
+
+### F3 → reel-state persistence, backoff, and queue gating
+
+- `reel-state.json` records, per media folder (movies) or per episode
+  (`folder#SxxEyy`), the video's mtime+size, status (`done`/`failed`),
+  attempt count, and last-attempt timestamp.
+- `_reel_needed` gates both scan-time queueing and the worker:
+  `done` entries are skipped; `failed` entries back off exponentially
+  (6 h → 12 h → … capped at 1 week); entries with no record fall back to a
+  cheap on-disk existence check, and existing reels are silently recorded as
+  `done` so future scans take the cheap path. This ends both the infinite
+  retries of unreadable files and the re-queueing of short videos.
+- The worker no longer rebroadcasts whole (stale) items: it sends narrow
+  `MovieShowreel` / `EpisodeReel` events, and the store updates only the reel
+  fields of the current entry (`set_movie_showreel` / `set_episode_reel`).
+- Reel state is persisted at scan finalize, on scanner `stop()`, and as soon
+  as the reel queue drains (a crash between scans no longer loses records).
+
+### F5 → bounded parallelism for downloads and TMDb fetches
+
+- Cast-profile downloads: `asyncio.gather` with a semaphore of 8.
+- TMDb title lookups (movies and series) are prefetched in parallel
+  (semaphore of 4) before the grouping loops, which then read the per-call
+  caches.
+- Season-detail fetches are prefetched in parallel (semaphore of 4) before the
+  season loop.
+- Per-item cover/backdrop/poster logic is unchanged (exists-check-fast when
+  warm).
+
+### Housekeeping (P5)
+
+- Dead `trigger_scan` removed (`is_scanning` kept).
+- TMDb-id index bookkeeping is incremental (see F1 above).
+- `_rebuild_tmdb_indexes` remains only for snapshot load and dedupe.
+
+---
+
+## 3. Measured results
+
+Subset root (163 items, 121 movies / 40 series entries, 469 video files),
+same network mount:
+
+| Scenario | Before | After |
+|---|---|---|
+| Touch one season of a 5-season series | other 4 seasons vanish until next full scan | 0.3 s rescan, one partial upsert (`scanned=[S04]`), store keeps all 5 seasons |
+| Steady rescan, nothing changed (same process) | 0.2 s | 0.2 s, 0 upserts, no writes |
+| Warm restart, unchanged library (fresh process) | 56.5 s (94 % ffmpeg re-probes) + 467 reel tasks queued | **0.2 s, 0 upserts, reel queue 0** |
+| First scan with warm TMDb cache but no probe cache | 56.5 s | 51.6 s once — writes `probe-cache.json` (469 records, 207 KB); subsequent runs skip all probing |
+| Permanently unreadable files (3 DoVi/libplacebo movies) | retried on every scan and every startup, error broadcast each time | recorded as failed once, skipped within backoff |
+| Cold scan, nothing cached | 975 s | not re-measured end-to-end; the dominant terms are now 8-way parallel (cast images: 3494 downloads measured at 3.7 s when warm) |
+| Deleted torrent | stayed in index forever | removed on the next completed scan via `Sync` |
+
+Unit-level checks (synthetic `IndexStore` + scanner state, no filesystem
+library involved): partial upsert preserves untouched seasons and replaces
+rescanned torrent files; multi-release episode union; sync removal cascades;
+single-episode reel updates; probe-cache save/load roundtrip; reel backoff
+math; reel-state persistence roundtrip across scanner instances.
+
+---
+
+## Appendix A — Blob storage options: scan-time vs runtime concerns
+
+**Status: reference only — not implemented.** The current on-disk format
+(one file per artifact) was deliberately kept. This appendix stays as
+documentation of the options if write amplification or file counts ever
+become an operational issue.
+
+The two concerns have opposite constraints, so they should be decided
+separately:
+
+- **Scan-time data** is written and read only by the scanner. Nothing in the
+  server serves it. Storage format is therefore a pure implementation detail
+  and can be changed freely.
+- **Runtime data** is delivered to the frontend as plain files via
+  `/api/assets/{root}/{movies|series|people}/{path}` (covers, posters,
+  backdrops, person photos) and `/api/media/{root}/{path}` (media files), with
+  etag/range streaming. Anything that replaces files here must keep an HTTP
+  serving story working.
+
+### A.1 Artifact inventory (measured)
+
+| Artifact | Class | Avg size | Count (full library) | Total | Written |
+|---|---|---|---|---|---|
+| TMDb response cache JSON | scan-time | 25 KB (median 9 KB) | ~8,500 | ~215 MB | on every uncached API request |
+| Probe results / scan state / reel state | scan-time | ~0.5 KB/record | ~3,000 records | ~1.5 MB | per processed file |
+| Person photos | runtime | 11.4 KB | ~22,500 | ~262 MB | once per person |
+| `cover.jpg` / season posters | runtime | ~77 KB | ~2,100 | ~164 MB | once per title/season |
+| `backdrop.jpg` | runtime | ~147 KB | ~1,460 | ~220 MB | once per title |
+| Reel clips (WebM/AV1) | runtime | ~450 KB | ~8,700 | ~4.0 GB | once per title/episode |
+| `index.json` snapshot | both | 7.5 MB | 1 | 7.5 MB | debounced, only when dirty |
+
+Reference point for the write-amplification math: on the network mount one
+small-file write costs ~0.2 s, while a single 7.5 MB sequential write costs
+the same ~0.2 s (~40 MB/s). So ~31,000 tiny files ≈ 1.7 hours of serialized
+write time, versus ~6 s for the same bytes as one bulk dump.
+
+### A.2 Scan-time blob store (TMDb cache, probe cache, scan state)
+
+Nothing here is served, so the only requirement is fast lookup + cheap
+persistence. Two workable shapes:
+
+- **RAM map + debounced atomic dump.** Plain dicts keyed by request hash /
+  file path, dumped as one binary file (length-prefixed msgspec or JSON blob,
+  optionally zstd-compressed) with tmp-write + rename, on the same
+  dirty-flag + debounce discipline `index.json` already uses. Effects: the
+  ~8,500 individual cache writes collapse into a handful of bulk flushes;
+  warm lookups become dict hits with zero filesystem calls. TMDb JSON
+  compresses ~10× (215 MB → ~20–25 MB), so a full dump is a sub-second write.
+  Caveat: holding all responses parsed in RAM costs ~200 MB for the full
+  library; storing raw response *bytes* and parsing lazily, or capping to
+  entries referenced by known index items, keeps this modest.
+- **SQLite (stdlib, WAL mode).** One database file, incremental commits, crash
+  safety without full dumps, and kernel page cache instead of explicit RAM
+  management. Better fit if the cache is allowed to grow unbounded, at the
+  price of slightly more code.
+
+Either way, keep the existing cache *semantics* unchanged: cache HTTP-level
+failures, never cache network errors. With persisted scan state in place the
+TMDb cache becomes write-rarely (new items only), which further lowers the
+value of elaborate engineering here — the simple dump is likely enough.
+
+### A.3 Runtime-served artifacts
+
+- **Reels, covers, backdrops, season posters: keep as files.** They are few
+  per title, tens-to-hundreds of KB, written exactly once, and benefit from
+  the existing etag/range file serving. No write-amplification problem.
+- **Person photos** (~22.5k files × 11.4 KB) are the one runtime class where
+  tiny files hurt at scan time. Three options, in increasing invasiveness:
+  1. **Keep files, fix only the scan-time behavior** — bounded-parallel
+     downloads, optionally capped to top-N billed cast. Zero changes to
+     serving; the cold-scan cost drops ~8× but the file count stays.
+     *(This is the option currently implemented.)*
+  2. **Blob db + serve from the db.** Person photos move into the same store
+     as above; the assets handler gains one branch for the `people` asset
+     type that streams bytes from the db instead of the filesystem.
+     Eliminates all 22.5k tiny files. If full RAM residency (262 MB) is
+     undesirable, use SQLite and let the page cache handle it.
+  3. **Hybrid lazy materialization.** The db is authoritative at scan time
+     (no tiny writes during scans); the assets handler writes the photo to the
+     conventional path on first request and serves it as a file thereafter.
+     Serving logic and URLs stay unchanged; disk usage appears only for
+     people actually viewed.
+
+Note that `index.json` itself is already the right shape: one atomic 7.5 MB
+file, rewritten only when dirty. The goal for everything else is simply to
+reach the same shape per concern.
+
+### A.4 Recommendation (if revisited)
+
+| Concern | Recommended treatment |
+|---|---|
+| TMDb response cache | RAM map + debounced single-file dump (SQLite if growth matters) |
+| Probe cache, seen-mtimes, reel-failure records | same dump mechanism, separate small files *(currently: three small JSON files, written only when dirty)* |
+| Person photos | option 1 now (parallel + lazy fetching); option 2 or 3 if file count becomes an operational issue |
+| Covers, posters, backdrops, reels | unchanged — plain files |
+| `index.json` | unchanged |
