 | Repository | Role |
 |---|---|
 | ToBePlayed-Auth | Users, login, settings, signs JWTs |
 | **ToBePlayed-Core** (this one) | Steam library, backlog, wishlist, stats; verifies JWTs |

 ## Features

 - **Steam sync**: owned games, playtime and achievements through the Steam Web API. Manual sync plus a nightly
-  sync. Resilience4j rate-limits every Steam call and tries the owned games up to three times (never again on a 4xx;
-  the wishlist and the calls a page waits for once); Caffeine caches game counts and player summaries. A sync commits its claim (`RUNNING`, with

+  sync. Resilience4j rate-limits every Steam call (2 per second) and retries only where a repeat is safe: owned games,
+  achievement schema and player achievements up to 3 times (`steamApi`, never on a 4xx); player summary and wishlist
+  once with an empty fallback (`steamApiOnce`); store, release and global-percentage calls not at all. Caffeine caches
+  player summaries (`steamPlayerSummary`), IGDB searches and the landing numbers, not game counts. A sync commits its
+  claim (`RUNNING`, with `sync_started_at`), its writes and its finish apart, and calls Steam and IGDB outside any transaction: a second
  sync sees `RUNNING` and skips, a failed one stores `FAILED`. A run older than `app.library.running-stale-minutes`
  can be taken over; its own finish then changes nothing.
 - **Backlog**: status (`BACKLOG`, `PLAYING`, `FINISHED`, `COMPLETED` = 100 %, `DROPPED`), rating 1–5, notes, priority,
  filters and sorting. "Pile of Shame" summary with a random suggestion of what to play.
- **Picker**: up to 10 backlog games for a time budget (IGDB normal time to beat) and a mood, mixed from four
-  sources, one per slot in turn: a game sharing moods with a random one of the user's 5 most played games (the
-  most shared moods first), the game waiting longest (oldest `firstSeenAt`), and a random one (HIGH priority first,
-  then MEDIUM, then the rest), and a random one of the first 5 games of the user's own backlog order that pass the
-  budget, mood and exclude filters (`NEXT_UP`). A source with nothing left gives its slot to a random game; no game appears twice.
-  Every game carries a `reason` (`source`, plus the anchor game for `SIMILAR` or `firstSeenAt` for `LONGEST`).
+- **Picker**: seven rows of up to 3 backlog games each, for a time budget (IGDB normal time to beat), in this order:
+  `NEXT_UP` (the first games of the user's own backlog order), `SERIES` (next in series: for each of the 6 most played
+  IGDB series the user played, one backlog part, the parts released after the latest played part first), `SIMILAR`
+  ("because you played": for each of the 3 most played games the first backlog game sharing its moods, no game twice),
+  `STUDIO` (for each of the 6 developers of the user's most played games, one backlog game with a credit of that
+  company, developer credits first; publishers are never anchors, so a big publisher adds at most one card),
+  `FRIENDS` (for each followed user with a public profile, one backlog game of the user that the friend finished or
+  played 5 h or more, strongest signal first; a finish and playtime need the `SUMMARY` or `STATUS` profile section (`FINISHED` alone lists only 12
+  games); `DROPPED`, hidden and removed games never count; the friend's current
+  display name, never an id),
+  `LONGEST` (oldest `firstSeenAt`) and `RANDOM` (the mood row: random, HIGH priority first, then MEDIUM, then the
+  rest). The mood filters only the `RANDOM` row; budget and exclude filters apply to every row. A row with no game is
+  left out. A game can show in more than one row. IGDB series (collections) and companies are stored per game
+  (`game_credit`, `game_credit_check`) and refreshed with the other IGDB data; a scheduled backfill
+  (`app.library.credit-backfill-*`) fetches them for existing games, 250 games per 30 s, so the two rows fill up over
+  time after a deploy. Every game carries a `reason` (`source`, plus the anchor game for `SIMILAR`, `seriesName` for
+  `SERIES`, `studioName` for `STUDIO`, `friendName`, `friendFinished` and `friendPlaytimeMinutes` for `FRIENDS` or `firstSeenAt` for `LONGEST`).
  Games already shown can be excluded for a reroll. Moods `STORY`, `COOP`,
  `CHILL`, `ACTION`, `SCARY` come from IGDB genres, themes and game modes; `SPEEDRUN` from speedrun.com.

  a warning, and the next view or sync asks again. Known limit: a dropped sync still answers `202`; the user
  starts it again.

+### PlayStation link
+
+`modules/psn_adapter` calls PlayStation's unofficial API (the public client of the PlayStation app, as the `psn-api`
+project ships it; all values in `app.psn.*`). `PsnAccountService` in `library` holds the use cases:
+
+- **Link** (`POST /api/library/psn-account`): the NPSSO (the user's `npsso` cookie from playstation.com) goes to
+  `/authorize` (the redirect is not followed: `Redirect.NEVER`), the `code` in its `Location` header to `/token`.
+  Only the **refresh token** is stored, in `user_psn_account`, sealed with AES-256-GCM (`SecretBox`, key
+  `APP_PSN_TOKEN_KEY`, base64 of 32 bytes). The NPSSO, the code and the access token are never stored; no log line,
+  answer or `toString` of a token type holds a secret. No key = the feature is off (`enabled: false`); a key of the
+  wrong length stops Core at start. A changed key makes stored links unreadable: the sync skips PlayStation and the user links again.
+- **Expiry**: the refresh token lives about 10 days (`refresh_expires_at`). A refresh that returns the same
+  refresh token keeps the stored expiry; a new one stores its own. The Settings page shows the date. The inbox gets one
+  note `PSN_EXPIRING` when the link ends within `app.psn.expiry-warning-days` (2) and one note `PSN_EXPIRED` when it has
+  ended or PlayStation refuses the refresh token (also an unreadable token). `user_psn_account.expiry_note` keeps what
+  was written, so a note comes once per link; a new link resets it. The library module writes `inbox_note` by SQL, as
+  the follow module does. An ended link makes the sync skip PlayStation until the user pastes a new NPSSO.
+- **Sync**: linking starts a sync (`LibrarySyncService.startAfterLink`). Inside the force-sync cooldown or while a sync runs, one sync per user is scheduled for the end of the cooldown (in memory, lost on restart; the next login sync covers it).
+  After that the PSN step (`PsnSyncStep`) runs in every library sync (login, nightly, manual) after the Steam fetch.
+  One refresh call, then `gamelist/v2` (200 per page, at most 1000 titles). `PsnTitles` cleans the names (no `™`/`®`, no
+  PS4/PS5 suffix) and joins the PS4 and PS5 versions of one `concept.id` into one line (name and platform of the most
+  played version, playtime summed, newest `lastPlayedDateTime`). `user_psn_title` remembers each title by its
+  `psn_key` (`c<conceptId>`, else `t<titleId>`) as `LINKED` (with the library key) or `DISMISSED`:
+  - A **new** title (not in the table, not in an open PSN import) is searched in IGDB. Same name and a version on the
+    line's platform: `ManualGameService.addGame` as `PSN`, no review, an `ADDED` change. The same game under another
+    spelling or platform that the user owns is only linked. Everything else goes to the review: a READY `PSN` import with
+    the matched rows is created, or the rows are appended to the one that waits (`reviewImportId`). The review page is
+    the import page; saving a PSN import links the checked lines and dismisses the unchecked ones for good.
+  - Every `LINKED` or `STEAM_OWNED` title also keeps its own platform, minutes and last played in `user_psn_title` (V44),
+    so the detail shows PlayStation play next to Steam's on a shared row. The Steam row's own playtime stays Steam's.
+  - A `LINKED` title updates its row (`source = PSN`, not removed): playtime, `last_played_at`, `PLAYTIME` changes and the
+    playtime history; `playtime_2weeks` is the sum of the history of the last 14 days. The minutes a title grew since
+    its stored play are booked on its last played day (Berlin), only when its last played moved; a title linked in this
+    run is the start point and books nothing (V49 dropped the old wrong rows). A game the user removed stays
+    `LINKED` and the sync does not add it again; its row stays removed, so the sync skips it until the user restores it:
+    a restore takes the stored title play (`psn_title_play`) and the sync updates the row again. Flyway V46 gave games
+    removed before (soft delete) a removed `PSN` row and turned a `MANUAL` row re-added on a `LINKED` key back to `PSN`. A game also owned on Steam stays one row (the Steam row wins).
+  - The first run of a user (no `user_psn_title` yet) is a baseline like the first Steam sync: its adds are a count in
+    `sync_result.imported_games`, not a list. PSN changes share the `sync_result` of the Steam part, so the banner and the
+    follow digest need no change.
+  - PlayStation and IGDB are called outside the sync transaction; the step catches every error, so PlayStation never
+    fails the Steam part. A user with a PlayStation link and **no Steam ID** syncs too (`user_steam_sync.steam_id` is
+    nullable): the Steam part is skipped, the same result, banner and digest apply.
+  The client cannot start a `PSN` import with its own rows.
+- **Limits**: one limiter `psnApi` for the whole server (1 request / 4 s, taken per HTTP request). Titles bought but
+  never started are not listed by PlayStation. A `PSN` row pays no rewards (no Steam proof), and a merge undo does not
+  move it back. The nightly loop is sequential.
+- **Trophies** (V40, `PsnTrophyStep`, called at the end of `PsnSyncStep.run`, outside the sync transaction, never throws).
+  It reuses the access token of the title part (`FetchResult.Titles` hides it in `toString`). Own tables
+  `psn_trophy_set`, `psn_trophy`, `user_psn_trophy_set`, `user_psn_trophy` and the cache `psn_title_trophy_set`, so the
+  Steam tables and the rewards (Steam only) stay untouched.
+  - **Summary**: 1-2 calls `trophy/v1/users/me/trophyTitles` give every set with defined and earned counts,
+    `trophySetVersion` and `lastUpdatedDateTime`. Hidden (`hiddenFlag`) sets, PS3/Vita-only sets and sets of unknown or
+    DISMISSED titles are not stored. A summary row is saved for every mapped set. **Gains** (`ACHIEVEMENTS` changes) come
+    from the earned total only; the first time a set is stored is a baseline.
+    Only a **complete** summary (sets returned = the API's `totalItemCount`) removes the user's stored sets that are no
+    longer in it (another account was linked); a partial one, after a broken page, removes nothing. Unlink deletes all of
+    the user's trophy rows.
+  - **Mapping**, two paths, the log line `PSN trophies user=… mapped by title id=N by name=M` shows which one worked.
+    (1) Exact: `titles/trophyTitles?npTitleIds=` (5 ids per call) answers title id to set; cached globally, "no set" is
+    asked again after 30 days. Not confirmed against the real service: a 4xx or an empty answer falls through to (2)
+    Name + platform, same account only: the clean name equals that of exactly one linked title and its platform is in the
+    set's platform list. Two games with the same name: the set stays unmapped. The set counts for the merge target of the game.
+  - **Lists only when changed**: the global trophy list when the stored `list_version` differs from `trophySetVersion`;
+    the user's earned list (also gives the rarity) when `list_updated_at` differs from `lastUpdatedDateTime`; a set with
+    0 earned needs no earned call.
+  - **Budget** `app.psn.trophy-calls-per-run` (30, about 2 min at 1 request / 4 s; the sync counts as stale after 5 min)
+    covers title id lookups and lists. Newest sets first; the rest follow in later syncs (the detail page then says the
+    list loads with the next sync). Three errors in a row stop the list calls, the summaries are still saved.
+  - **Presentation**: `perfect()` = platinum or all earned; one entry per set, one per game for the counts (perfect set,
+    else best percent). A hidden trophy that is not earned has no name and no description. Stored image URLs must be `https://`.
+  A sync costs 2 calls (token, titles) plus the summary and the changed lists.
