# Isis Florence-2

## Purpose

Admin lane console for the Florence-2 region codec. The operator submits
pixel-space bounding boxes as JSON; the codec quantizes them into Florence-2
`<loc_N>` location tokens (0–999 grid) and returns the encoded token string plus
the decoded round-trip regions and any quantization error. Reads and encodes via
`/v1/admin/isis/florence2`; admin-scoped and fail-closed.

## Entry points

- Embedded as the "Florence-2 Lane" inside `/studio/isis/comfyui-nodes`
- Sibling quick-action from `/studio/isis/instantid`
- Studio index (`/studio`)
- Direct URL / bookmark (AAA entitlement required)

## Layout regions

`page.tsx` mounts `<ShellLayout active="studio">` (no breadcrumb panel) and three
panels: the workspace, the Route Map, and sibling quick-actions.

- **Header**: shell header
- **Workspace panel** (`data-isis-florence-2-workspace`):
  - `<h1>` (`WorkspaceHeading`) "Isis Florence-2 Workspace"
  - Summary paragraph (`data-isis-florence-2-summary`)
  - **Live Florence-2 Region Codec lane** (`data-frl-lane`, `<h2
    data-frl-heading>Live Florence-2 Region Codec</h2>`): a JSON region form
    (`data-frl-form`) + result (`data-frl-result`)
- **Route Map panel** (`data-isis-florence-2-route-map`): `<h2>Route Map</h2>`
  over the route map (5 entries)
- **Sibling quick-actions panel**: `/studio/isis/instantid`, `/studio`

## States

- [ ] **Loading** — `data-frl-loading`
- [ ] **Unauthorized** — 401/403 admin-scope fail-closed; `data-frl-unauthorized`
- [ ] **Error** — non-OK / malformed; `data-frl-error`
- [ ] **Ready (form)** — region form renders
- [ ] **Result** — `data-frl-result` with `data-frl-tokens`, `data-frl-decoded`,
      decoded `data-frl-region-row` rows, and quantization error
      (`data-frl-max-error` / `data-frl-error-px`); encode failure →
      `data-frl-encode-error`

## Interactions

### Region codec form (`data-frl-form`)

- [ ] **Florence regions (JSON)** (`data-frl-payload`, textarea,
      `aria-label="florence regions json"`)
- [ ] **Encode regions** (`data-frl-submit`, submit) — `POST
      /v1/admin/isis/florence2/encode-regions`

### Route Map

- [ ] **Route-map articles** ×5

### Sibling quick-actions

- [ ] **Open Isis InstantID workspace** → `/studio/isis/instantid`
- [ ] **Back to Studio workspace index** → `/studio`

## Data & contracts

- **Reads**: `GET /v1/admin/isis/florence2` (codec catalog probe)
- **Writes**: `POST /v1/admin/isis/florence2/encode-regions` (quantize regions →
  location tokens, with decode + error)
- **Realtime**: none
- **Caching**: client fetch on mount, `cache: 'no-store'`, `buildBffAuthHeaders()`
- **Auth/role check**: admin-scoped, fail-closed (401/403); route AAA-gated
  (`florence-2` in `AAA_ONLY_STUDIO_ROUTES`)
- **Component sources**:
  - `apps/oshun/web/src/components/studio/StudioIsisFlorence2Workspace.tsx`
  - `apps/oshun/web/src/components/studio/StudioIsisFlorence2RouteMap.ts`

- Studio overview: [`../../studio-overview.md`](../../studio-overview.md)

## Open questions / known gaps

- [ ] No breadcrumb on this route — navigation via sibling quick-actions
- [ ] Summary copy references "dense expert-mode controls"; the only wired control
      is the region codec lane — confirm whether further VL tooling is planned
- [ ] Route-map sub-paths are declared but not yet implemented as separate pages
