Data model

A condensed reference of the main Postgres tables. The authoritative source is server/migrations/.

Catalogue layer

Table	Purpose	Key fields
figures	The shared catalogue of figurines	name, figure_type, manufacturer_id, release_date, msrp_amount, is_nsfw, slug
manufacturers	Companies (Good Smile, Alter, …)	name, slug
series	Anime / game / manga series	name, slug
characters	Character names	name, slug
sculptors	Sculptor credits	name, slug
figure_series	Many-to-many figure ↔ series	figure_id, series_id
figure_characters	Many-to-many figure ↔ character	figure_id, character_id
figure_photos	Shared catalogue photos	figure_id, storage_key, is_primary, position

User layer

Table	Purpose	Key fields
users	User accounts	username, email, password_hash, is_admin, nsfw_visibility, preferred_currency, public_profile_show_nsfw
owned_items	Personal collection rows	figure_id, condition, price_amount, price_currency, shipping_amount, price_fx_rate, value_amount, value_currency, purchase_date, store_id, cover_photo_id, cover_scan_id, sort_order, archived_at
photos	Personal photos	owned_item_id, storage_key, position
scans	360° turntable frames	owned_item_id, storage_keys (array)
wishlist_items	"Want to own" list	figure_id, max_price_amount, max_price_currency, note

Money columns always come in pairs — NUMERIC(12,2) amount + CHAR(3) ISO currency — and store the original amount; display conversion is a reading layer (Money & currencies). price_fx_rate (also on preorders) is the currency → EUR rate frozen when the cost was recorded, powering the drift-free plus-value; NULL (pre-v0.23 rows) falls back to today's rate.

Pre-order lifecycle

Table	Purpose	Key fields
preorders	Pre-order rows tied to an owned_item	owned_item_id (unique), status, release_date_original, release_date_current, tracking_url, price_amount, price_currency, price_fx_rate, deposit_amount, deposit_refund_amount, shipped_at, estimated_delivery_days
preorder_date_history	Slip log	preorder_id, previous_date, new_date, source, note

Market prices

Table	Purpose	Key fields
figure_provider_prices	Latest fetched market price per figure (overwritten each sweep)	figure_id (PK), amount, currency, source, matched_version, fetched_at
figure_price_history	Append-only price change points (only when the price moves)	figure_id, amount, currency, source, matched_version, recorded_at

Both are filled by the admin-scheduled price sweep; the history drives the sparklines + evolution charts on La Cote.

Operations

Table	Purpose	Key fields
app_settings	Live instance policies (no restart)	key (gsplat.creation_policy, cote.price_cron), value
server_job_runs	Historized scheduled-job runs (30 kept per job)	job_name, triggered_by, state, result (JSONB), error_message, started_at, finished_at
external_lookups	TTL cache for external fetches (FX rates, scrapes)	provider, lookup_key, payload, fetched_at
stores	Boutique registry (slug-deduped, user-created)	name, slug

Notifications

Table	Purpose	Key fields
notifications	Per-user notification log	user_id, event_type, payload (JSONB), read_at
notification_subscriptions	Per-channel routing	user_id, channel_type, event_type, enabled
notification_channels	System-level channel configuration	channel_type, enabled (admin toggle)
notification_dedup	Prevents double-fires	user_id, dedup_key, created_at
web_push_subscriptions	VAPID subscriptions	user_id, endpoint, keys

MangaCollector synergy

Table	Purpose	Key fields
manga_servers	Admin-curated allow-list of MangaCollector origins	base_url (unique, normalized origin), status (pending / approved / revoked), submitted_by, reviewed_by, reviewed_at, note

The link itself lives on users — manga_server_id (→ manga_servers) + manga_slug. The join to the catalogue is series.mal_id (populated from the AniList idMal), so a figure's series and a MangaCollector library entry line up with no manual mapping. Cross-link fetches only fire when the linked server is approved.

Activity + achievements

Table	Purpose	Key fields
activity_events	Audit log for the user feed and stats	user_id, kind, payload, created_at
achievements	Unlocked achievements per user	user_id, code, tier, unlocked_at

Auth

Table	Purpose
oidc_identities	Federated identity links (Google, generic)
tower_sessions	Server-side session storage

Migrations

All migrations live in server/migrations/ as plain .sql files, wrapped by server/src/migration/m2026*_*.rs modules. The SeaORM MigratorTrait runs them in lexical order on backend boot.

Idempotent by design (IF NOT EXISTS, OR REPLACE), so a restart is always safe.
