v2.11.3 — Twin-spool repair finished: the two chips of a spool now agree on remaining weight + container weight (repair master = most-recently-updated chip; flag twinFix.v5, re-runs once), so the stock value is consistent and matches a friend's view. Mis-linked pairs (two different products glued by the timestamp auto-linker) are now UN-linked, and the auto-linker guards on product identity so it stops re-merging them. Rack comparison made idempotent (canonical slot key) — no more repair ping-pong.

Detail panel: "Ranger auto" now updates the Emplacement section IN PLACE (surgical swap of just that section — no full rebuild, so the panel keeps its scroll + media, no jump-to-top). Emplacement card restyled: icon-only auto-store button (larger 3-star "AI" sparkle, hover lights up the whole card via :has()), and a short one-word not-stored label ("Unracked"/"Non rangée"/…) across 9 locales.

+## v2.11.3 — 2026-07-15
+
+### Changed
+
+- **Twin-spool repair — source of truth is now the most-recently-updated chip.** The one-shot reconciliation (`reconcileTwinFields`) previously took whichever chip the inventory *displayed* (the smaller-UID one `deduplicateTwins` keeps) as authoritative. It now picks the chip with the greater `updatedAt` — the one you touched last (a fresh weigh-in, a just-set container) — so a conflict resolves to your latest intent even when the displayed chip held a stale value; ties fall back to the displayed chip for determinism. `updatedAt` parsing handles a live Firestore `Timestamp`, the serialized `{seconds}` / `{_seconds}` forms and a raw epoch — `renderer/inventory.js`.
+- **Twin repair now guards on product identity and breaks bad links.** A pair is force-synced only when both chips share the same `_spoolGroupKey` (`id_product` for Tiger Tag+, brand/material/colour/aspect for maker). Two chips that are genuinely *different* products were mis-linked (see the auto-linker fix below); the pass now clears `twin_tag_uid` on both docs so they become independent spools again — timestamp-neutral, counted as `unlinked` and shown in the Debug repair line. This stops one spool's fields overwriting an unrelated one's, and un-merges two different products that were shown (and valued) as one — `renderer/inventory.js`.
+- **Spool detail panel — storage-location card redesigned.** The auto-store control is now an icon-only button: a larger (16 px) sparkle with an `aria-label` (no text label, no hover title), a clear hover state (soft-primary background + border, icon turns primary and scales up), and — via `:has()` — hovering it lights up the whole location card (border, fill, label, box icon) so it is obvious what the action will fill. The not-stored status is a one-word label ("Unracked" / "Non rangée" / …) instead of "Pas rangée dans un rack". `icon_sparkle.svg` was redrawn from a magic-wand-plus-sparkles into a filled **3-star "AI" glyph** (also used by the rack autofill menu item) — `renderer/inventory.js`, `renderer/css/10-settings.css`, `assets/svg/icons/icon_sparkle.svg`.
+
+### Fixed
+
+- **The two chips of a twin spool now agree on remaining weight and container weight.** The repair mirrored image / container-id / rack / tags / note between twins but never the **weight**, so one physical spool's two chips could report different grams (e.g. 194 g vs 1000 g) — making the stock value swing with whichever chip was displayed, and diverge between your view and a friend's. Weight (`weight_available`) and container weight are now aligned to the freshest chip (timestamp-neutral); the container field compares `container_weight`, not just `container_id`, so a weight-only drift is repaired. Repair flag bumped to `tigertag.twinFix.v5.*` so every account re-runs the pass once — `renderer/inventory.js` (`reconcileTwinFields`, `_TWIN_FIELDS`).
+- **The twin auto-linker no longer merges two different products.** `autoLinkTwinsByTimestamp` paired chips by `id_tigertag` + chip-timestamp proximity (≤ 2 s) alone, so two unrelated spools programmed seconds apart at the factory were glued into one twin — and re-glued on every snapshot, undoing the repair's unlink. It now also requires an identical `_spoolGroupKey`. This is the root cause of the mis-linked pairs the repair breaks — `renderer/inventory.js`.
+- **The twin repair is now idempotent on the rack slot.** The rack field compared both the modern `rack` object and the legacy flat `rack_id`, but the copy only ever wrote the object, so a pair with mixed shapes never converged and the repair rewrote it on every pass (the "docs filled" count ping-ponging on repeated Debug runs). Comparison now uses a canonical slot key (`_twinRackSlot`) tolerant of both shapes — `renderer/inventory.js`.
+- **The detail panel reflects an auto-store immediately, and surgically.** Clicking "Ranger auto" wrote only the `rack` field (no timestamp), which `_rowSignature` ignores, so the "Emplacement" section did not repaint until the panel was reopened; forcing a full rebuild instead reset the panel scroll (a visible jump to the top) and reloaded the image/video. The structural signature is now split into a core (everything except the slot) and a location signature, so a location-only change swaps just the `.panel-storage-loc` node and re-wires it (`_patchDetailLocation` / `_wireStorageLoc`), leaving scroll and media intact — `renderer/inventory.js`.

 ## Added
 
 ## Changed
-- **Twin-field repair now resolves conflicts, not just gaps — the DISPLAYED spool wins.** The v2.11.1 one-shot repair filled a twin's hollow chip but left genuine conflicts (both chips carrying a *different* container or custom image, set on each before mirroring existed) untouched. Real friend data showed 8 such pairs (7 container, 1 image), some with different container *weights* → the displayed net weight depended on which chip the UI happened to show. The reconciler now treats the twin the inventory actually displays (the one `deduplicateTwins` keeps — chosen before the sort, so independent of the user's sort column) as the source of truth: its per-spool fields overwrite the other chip's, resolving conflicts to exactly what the user sees; a hollow displayed chip is still filled from its twin. Flag bumped to `tigertag.twinFix.v2.*` so accounts that already ran the fill-gaps pass get one more pass to settle conflicts; still timestamp-neutral (never writes the chip `timestamp` or `updatedAt`) — `renderer/inventory.js` (`reconcileTwinFields`).
+
+## Changed
+- Twin-tag reconciliation source of truth is now the **most-recently-updated chip** (`max updatedAt`), not the displayed/smaller-UID spool — the master is evolutive, following whichever chip you touched last (fresh weigh-in, just-set container…). On a tie it falls back to the displayed spool for determinism. This fixes conflicts where the displayed chip held a stale value that the old rule would have wrongly kept. `updatedAt` parsing handles a live Firestore Timestamp, the serialized `{seconds}`/`{_seconds}` forms and a raw epoch. — `reconcileTwinFields`, `renderer/inventory.js`
+- Twin reconciliation now guards on **same product identity** and **breaks bad links**: a pair is force-synced only when both chips share the same `_spoolGroupKey` (id_product for Tag+, brand/material/colour/aspect for maker). A pair whose two chips are *different* products was mis-linked — the pass now clears `twin_tag_uid` on both docs so they become independent spools again (timestamp-neutral), counted as `unlinked` and surfaced in the Debug repair line. This prevents one spool's fields from overwriting an unrelated one's, and fixes two genuinely-different products being shown (and valued) as one — `reconcileTwinFields`, `renderer/inventory.js`
+
+## Changed
+- Detail panel "Emplacement": the **auto-store button is now icon-only** — a larger (16 px) sparkle icon with `aria-label` (no text label, no title), and a clear hover state (soft primary background + border, icon turns primary and scales up) so it's obvious the cursor is on it; hovering the button also **lights up the whole location card** (border + fill + label + box icon in primary, via `:has()`) so the user sees what the action will fill. The not-stored status is a short one-word label ("Unracked" / "Non rangée" / …) instead of the long "Pas rangée dans un rack" phrase — `renderer/inventory.js`, `renderer/css/10-settings.css`
+- `icon_sparkle.svg` redrawn as a filled **3-star "AI" sparkle** (was a magic-wand + sparkles) — the conventional AI-action glyph; shared by the detail-panel auto-store button and the rack autofill menu item — `assets/svg/icons/icon_sparkle.svg`
 
 ## Fixed
+- Detail panel now reflects an **auto-store** ("Ranger auto") immediately **and surgically**: the location section is patched in place, never a full rebuild. `refreshOpenDetail`'s early-return was gated on `_rowSignature` alone (which omits the rack slot), so an auto-store — writing only `rack`, no timestamp — never repainted the "Emplacement" section until reopened; a naive fix rebuilt the whole panel, which reset the scroll (a visible "jump to top") and reloaded the image/video. Now the structural signature is split into a core (everything except the slot) + a location signature: a location-only change swaps just the `.panel-storage-loc` node and re-wires it (`_patchDetailLocation` / `_wireStorageLoc`, mirroring the toolbox surgical pattern), keeping scroll + media intact — `renderer/inventory.js`
+- Twin auto-linker (`autoLinkTwinsByTimestamp`) no longer pairs two chips that are **different products**: it linked by `id_tigertag` + chip-timestamp proximity (≤2 s) alone, so two unrelated spools programmed seconds apart got merged into one twin (and re-merged on every snapshot, undoing the reconciler's unlink). It now also requires an identical `_spoolGroupKey` — the root cause of the mis-linked pairs — `renderer/inventory.js`
+- Twin reconciliation is now **idempotent on rack**: the field compared the `rack` object AND the legacy flat `rack_id`, but `copy` only ever wrote the object — so a pair with mixed rack shapes never converged and the repair re-wrote it on every pass (visible as the "docs filled" count ping-ponging on repeated Repair clicks). Comparison now uses a canonical slot key (`_twinRackSlot`) tolerant of both shapes — `renderer/inventory.js`
+- Twin-tag spools now keep their **remaining weight** and **container weight** in sync between the two chips — the repair pass (`reconcileTwinFields` / `_TWIN_FIELDS`) previously mirrored box/picture/rack/tags/note but not weight, so the two chips of one physical spool could report different grams (e.g. 194 g vs 1000 g). This made the stock value swing depending on which chip was displayed, and diverge between own-view and friend-view. Now the two docs align to the freshest chip's weight (timestamp-neutral); the container field also compares `container_weight` (not just `container_id`) so a weight-only drift is repaired. Repair flag bumped `twinFix.v2 → v3` so accounts re-run the pass once — `renderer/inventory.js`

+# Tiger Studio Manager v2.11.3
+
+The final round of twin-tag spool cleanup, plus a tidier auto-store.
+
+## Fixed
+
+- The two linked NFC tags of one spool now always agree on the **remaining weight** (and the box), so the stock value reads the same whichever tag the app happens to show — and matches what a friend sees on your inventory.
+- Two genuinely **different** spools that had been wrongly linked together as one are now separated back into two, each with its own details and value.
+- Clicking **Auto-store** now updates the spool's location on the spot, without the details panel jumping back to the top.
+
+## Changed
+
+- The **Auto-store** button in a spool's details is now a clear sparkle icon that lights up — along with the whole location card — when you hover it, so you can see exactly where the spool will go. The "not stored" label is shorter and reads cleanly in every language.
