+## v2.35.0 — 2026-10-09
+
+### Added
+
+- **Prusa printers (beta).** Every Prusa running PrusaLink — MK4/MK4S, MK3.9/MK3.9S, Core One, XL (1/2/5 tools), MINI/MINI+, MK3S+ / MK2.5S via Raspberry Pi — with or without MMU, with or without camera. LAN only (Prusa Connect has no public API). First shipped as `v2.35.0-beta.1`.
+  - Transport in main: `prusa:http` (HTTP Digest auth with a cached challenge, optional `X-Api-Key`, tight path allowlist, GET/PUT/DELETE/HEAD, binary for thumbnails/snapshots) + `prusa:probe` (one unauthenticated `GET /api/version`: 401 Digest "Printer API" / PrusaLink server header / version body); `window.prusa` in `preload.js`.
+  - Driver `renderer/printers/prusa/index.js`: 2 s `/api/v1/status` poll (state map incl. `ATTENTION`, nozzle/bed/chamber temps, progress, time left, fans, speed/flow), `/api/v1/job` on a new job + every 10 s (name, thumbnail → data URL, G-code metadata), `/api/v1/info` + `/api/version` once (MMU, serial, camera, firmware); reconnect backoff + re-find (`refind.js`, ARP MAC); auth / old-API / command errors as banners + one toast.
+  - Slots: MMU → 5 bays (one "MMU" board unit), XL → T1…Tn from the model catalog `tools`, else E1; filled from the job's `filament_type` / `extruder_colour` metadata while it runs (PrusaLink reports no loaded filament).
+  - Pause / resume / stop on the side card and the printer board (`controlJob`, hold-to-confirm 1.2 s / 1.5 s).
+  - Camera: Buddy3D over local RTSP (`rtsp://<ip>/live`, ffmpeg → JPEG, `prusa:cam-start-rtsp`) or PrusaLink `/api/v1/cameras/snap` every 2 s; one feed per printer shared by side card, board and camera wall (not in the detached camera window yet).
+  - Add flow: HTTP `/api/version` sweep of the local /24s + extra subnets, or manual `host[:port]`, then PrusaLink password, optional user, optional Buddy3D address. Model catalog `data/printers/prusa_printer_models.json`; placeholder brand mark + model image.
+  - Marked beta: "Beta" tag in the add-printer picker (`meta.beta`), beta notice at the top of the live block.
+- **Elegoo Centauri Carbon 1 (beta) — SDCP v3** as a second Elegoo transport (issue #41): `M99999` discovery on UDP 3000 (`elegoo:sdcp-discover` sweep + `elegoo:sdcp-probe`, in parallel with the CC2's MQTT probe), WebSocket `:3030/websocket` without auth from the renderer (`renderer/printers/elegoo/sdcp.js`): status (Cmd 0 + pushes) → state / progress / layers / time left / temps / fans / speed; attributes (Cmd 1, MAC kept for the IP re-find); camera (Cmd 386 → MJPEG :3031); pause / resume / stop (129 / 131 / 130 — not yet confirmed on firmware 1.4.x). Every exported entry point of `elegoo/index.js` hands over when `printer.protocol === "sdcp"`. CC1 form asks only the IP (`sdcpSchema`, writes `protocol: "sdcp"`); catalog entry "Centauri Carbon (Beta)"; `PROTOCOL.md` §25.
+- **Per-printer settings schemas within a brand**: `schemaFor(printer | prefill)` on the brand + `fixed` values written with the doc; used by the form, the save, the scan multi-select (`scan-pick.js`, required fields asked per candidate) and multi-add (`_printerSchemaFor`, `printerRequiredFields(brand, prefill)`).
+- **Catalogue product card.** A product opened from the Catalogue views gets its own side card (`#productCardPanel`, catalogue mode): illustration, identity + chips, "Already N in your inventory", a **Product sheet** button (opens the full product card beside it; a second press closes it), then a 2 × 2 grid of calls to action — **+ Inventory** (`_catalogCreate`), **+ Wishlist** (list picker), **+ Cart**, **+ Favorite** (✓ states) — then description, print settings, documents and details; no weight bar. ★ / cart / lists use the row "+ Inventory" would create (`catalogRow`), so they land on the same product record as the spools. Picking another product while the card is open slides the new card over a ghost of the old one (`_ghostSwapPanel`, ghost one z-slot under panels at z ≤ 100) and closes a product sheet left on the old product.
+- **Catalogue — nothing found.** A search / filter set with no match shows an empty state with **Create it by hand**, opening the Add-product card (`[data-cv-create]` → `openAddProductPanel`).
+- **Full catalogue data on catalogue spools.** Spools created from the catalogue, converted to TigerTag+ or refreshed from the API store `catalogProduct`: the local `id_catalog.json` entry enriched field by field with what `product/get` adds (description, documents, images, filament block, nozzle / dryer / bed, fan speeds, slicer profiles in `metadata`, brand logo / site, dates); the chip still gets only protocol fields (`_catalogFullRecord`, `_productApiFields`, `_refreshApiData`, `normalizeRow`). Documented in `docs/firestore-schema.md`, the backend `README.md` and the MCP data guide.
+- **Favourite MasterSpools.** A ☆ on every MasterSpool in the container picker (`favorite: true` on `users/{uid}/containerOverrides/{id}`, beside the weight correction — resetting one keeps the other). Favourites get their own group at the top of the picker; a refill with favourites always asks, the picker narrowed to the favourites (any brand) + the brand's own MasterSpools, skipped only when the favourite is the brand's only MasterSpool (`containerIsFavorite`, `_cpToggleFavorite`, `_containerChoice`).
+- **Container picker filters**: Cardboard / Plastic / MasterSpool chips under the search (one at a time, press again for all; reset on open; combined with the search and a narrowed list) — `_cpSetKind`, `CONTAINER_KIND`.
+
+### Changed
+
+- **One product card instead of two** (PR #39 by @Ptitlouis6012, then redesigned): "Product info" and "Product card" merged into one wide card — hero (illustration flush top-left, 236 px with a 20 px colour frame; identity; aspect / weight chips; HEX colour badges; 2-line description), two figures (**In stock** — "N spools" or "stock/minimum" — and **Estimated value**, stock × unit price HT/TTC), buy-link / price buttons, actions (+, list, to-order, ★) in a row beside the ✕ that scrolls with the content, then three tabs kept across re-renders: **Info** (print settings as 2 × 3 tiles; **Product details** — brand linked to its site with a globe, range, material, colour, net weight, product id → catalogue, type, diameter, fan speed; **Stock** — minimum, current, value; **Slicer profiles** — Bambu Studio / Creality Print, when known; note with a 0/500 counter; personal links), **Documents** (documents + video, orange count bubble on the tab) and **Notes** (tags, SKU / EAN, raw JSON in debug). Friend products keep the read-only card. i18n `reorderPanelTitle`, `reorderOpenProductCard` removed.
+- **Container on a new spool** (`_containerChoice`, keyed on `brandId` == `id_brand`): not a refill → the brand's only container silently, several → picker narrowed to the brand's, none → narrowed to the generic ones ("Without MasterSpool" never offered); refill (`info1`) → the brand's only MasterSpool, several → narrowed to them, none → every MasterSpool. The narrowed picker says why and has "Show all"; questions are queued one at a time and only for spools added during the session. Replaces the old fallback to the first generic entry ("Without MasterSpool", 0 g).
+- **Inventory reads like the catalogue** (issue #43): grid cards titled with the product name ("PETG HF - Blue" — the catalogue title for a catalogue spool, else "<series> - <colour>") over "Brand · Material" (`spoolCardTitle`, `spoolCardSub`); the table and grouped spools show the material with its series (`materialWithSeriesAspect`).
+- Elegoo: the Centauri Carbon 2 is named as such everywhere (catalog typo "Centaury" fixed, tutorial), a Centauri found over MQTT is no longer mistaken for another model, the empty scan names the supported models.
+- `docs:check` accepts prerelease versions.
+
+### Fixed
+
+- **Inventory search finds what the catalogue finds** (issue #43): one word-based search shared by the inventory, the Products views and the catalogue — every word must appear among brand, series, product name, material, aspects, colour, note, SKU / EAN, UID, tags, capacity — instead of the whole phrase in one field ("Bambu PETG HF" found nothing). Exact-code shortcut unchanged (`_searchTokens`, `_hayHasAll`, `_rowSearchHay`).
+- **Product card showed "In stock: 0" for a catalogue product you own**, and a minimum / ★ set there landed on another record: the preview was built on a "PRODUCT_" row instead of as the TigerData+ the catalogue creates ("tt:<id>"). Now built on a chipless id, keyed by `_spoolProductKey`; rows synthesised from a product record carry `_productHash` and stock / row lookups match on it. A one-time `_healGhostProducts` merges the ghost records the bug left (flags OR-ed, larger minimum, empty fields filled, tags united) and deletes them.
+- Printer board: dropping a printer group onto another no longer pushes the other printer's widgets down (PR #40 by @Ptitlouis6012; follow-up issue #42) — `_planSettleColumns`.
+
+### i18n
+
+- Added the Prusa set (`printerHintPrusa*`, `printerLblPrusa*`, `printerHelperPrusa*`, `prusa*`), `printerHintElegooSdcpIP`, `elgSdcpCmdRefused`, `betaTag`, `printerBetaNote`, `cpHint*`, `cpShowAll`, `cpFavorites`, `cpFavAdd`, `cpFavRemove`, `cpKindCardboard`, `cpKindPlastic`, `pcCta*`, `pcCatOwned`, `pcOpenSheet`, `det*` (fan, profiles, brand site, …), `sectionDescription`, the `ro*` product-card set, `roPanelSlicer`, `catEmptyTitle`, `catEmptySub`, `catEmptyCta` — 11 locales. Changed `elegooScanEmpty`. Removed `reorderPanelTitle`, `reorderOpenProductCard`.

 # Tiger Studio Manager — Feature Catalogue
 
-Tiger Studio Manager is the Electron desktop companion to the TigerTag ecosystem: a filament-inventory manager built around RFID/NFC-tagged spools ("TigerTag" chips), a fully-digital "TigerData" tier (and its catalogue-identified "TigerData+" rung), live 3D-printer integration across seven brands, physical storage/rack management, a Firebase-backed social layer (friends, shareable wishlists, public profiles), and companion hardware (TD1S color sensor, TigerScale, TigerSpool printer reader, TigerPOD dual-reader stand). This document catalogues every **shipped** feature, grouped by domain, current as of **v2.35.0-beta.1**. Per-version release detail lives in `CHANGELOG.md`; forward-looking / in-progress work lives in `ROADMAP.md`.
