Cross-frontier panel (Gróa/Hulda/Regin) on the v0.19.2 web surface, triaged: - FIX (Gróa #1, drift): the turn EventSource `onerror` (raw transport drop) now calls hideThinkingNote() — a drop mid-reasoning no longer leaves the "<Agent> is pondering…" line + its setInterval running (INV-LIFECYCLE). - FIX (Gróa #4 + Hulda #1, convergent drift): openAdminEvents now closes the EventSource + clears state.adminES on `stream_error` (server signalled end) and on a PERMANENT onerror (readyState CLOSED) — native EventSource no longer auto-reconnects into a retry loop; transient CONNECTING drops still reconnect. - TEST (Gróa #2 + Hulda #3): test_routes_registered asserts the 3 new routes; test_state_attached asserts app.state.admin_key (create_app POST-001/002). - TEST (Gróa #3 + Regin #3): AdminEvents stream_error-on-connect-failure test — upstream non-200 -> exactly one `stream_error` frame, then ends (POST-003). - CONTRACT (Hulda #2 + Regin #2, accepted): clarified the Tools inventory renders NAMES only by design (descriptions live in the BifrostState pane); code unchanged. Also lands the web_debug_surface contract as the trail. Accepted-no-op: 403-bifrost / non-404-tools tests (identical code path to the tested 404). Panel found ZERO functional server-side drift; INV-004 escaping confirmed clean across the new panes. 60 web tests pass; JS + ruff clean.

contract_version: "2.1"

module: "ratatoskr.web"
|
||
purpose: "v0.19.2 web debug-surface parity: 3 admin/debug panes (Tools inventory, BifrostState, AdminEvents SSE) proxied server-side with the admin key server-held, plus a reliable PAD-refresh poll and a non-engine reasoning indicator in the transcript."
|
||
target_module: "ratatoskr.web (server.py routes + entrypoint.py + static/index.html)"
|
||
scope: "v0.19.2 web debug-surface parity — bring the browser surface (now the PRIMARY debug surface) to TUI parity. THREE new admin/debug panes proxied server-side + TWO transcript affordances. (1) Tools inventory: GET /api/sessions/{id}/tools proxies owner-scoped get_session_tools into the tools pane (what the LLM HAS at turn-fire), above the live tool events. (2) BifrostState pane: GET /api/sessions/{id}/bifrost proxies admin-scoped get_session_bifrost; the admin key is SERVER-HELD (app.state.admin_key from RATATOSKR_ADMIN_API_KEY), never sent to the browser. (3) AdminEvents pane: GET /api/admin/events is an SSE proxy of stream_admin_events, session-filtered SERVER-side (heartbeats + other-session events dropped), re-emitted under a fixed 'admin_event' name so every dotted type renders with one browser listener. (4) PAD refresh: the persona/affect pane polls a bounded window instead of a single 2s shot that raced the post-turn-async affect.emit. (5) Reasoning indicator: an ephemeral, clearly-non-engine transcript line on `thinking` deltas, cleared when text begins. Direct in-session TDD (the #17/#18 pattern); this contract is authored post-implementation to anchor the heid code review (the client wrappers get_session_tools/get_session_bifrost/stream_admin_events are already contracted in the sessions/sse_client specs — this contract governs the WEB proxy + presenter surface only)."

assumptions:
|

- "The three client wrappers exist and are already contracted: get_session_tools(client, session_id)->dict (owner-scoped, consumer bearer; non-200 -> SessionApiFailed), get_session_bifrost(client, session_id, *, admin_key)->dict (OVERRIDES Authorization with admin_key; non-200 -> SessionApiFailed), stream_admin_events(client, *, admin_key)->AsyncIterator[AdminEvent] (non-200 -> SseConnectFailed; mid-drop -> SseConnectionDropped). The web routes are thin proxies over them; they add NO new upstream semantics."
|
||
- "AdminEvent = {id:int, type:str, timestamp:str|None, data:dict}. data MOST carry session_id (INV-049). type is a dotted namespace (session.*/turn.*/key.*/system.*)."
|
||
- "The web SPA is a single static/index.html served per-request via FileResponse (edits land on browser refresh; server code changes need a restart). Model/tool/admin content is UNTRUSTED text (INV-004) — every render path escapes first (esc() via textContent, or JSON.stringify wrapped in esc())."
|
||
- "The internal-LAN trust model (0.0.0.0, no auth/TLS/CORS) is deliberate operator direction. Admin-scoped DATA becoming LAN-visible is accepted under that model; the admin KEY must nonetheless never cross to the browser."
|
||
- "Tests: respx mocks the upstream endpoints (absolute w.example URLs) driven through the TestClient; the AdminEvents SSE proxy is tested with a finite mocked SSE byte-stream asserting the filter + fixed event name. Live-proven against ratatoskr:sindra on personal :8081."

# v0.19.2 — web debug-surface parity (BifrostState · AdminEvents · Tools · PAD-poll · reasoning)
|
||
|
||
## Context
|
||
|
||
The browser surface is now the operator's PRIMARY debug surface, and it lagged the
|
||
TUI: the TUI gained Tools/BifrostState/AdminEvents panes (v0.18.9–.11) that were never
|
||
ported to the web. This change closes that gap and adds two transcript affordances (a
|
||
reliable PAD refresh + a reasoning indicator). The client wrappers already existed and
|
||
are contracted elsewhere; this contract governs the WEB proxy routes + the SPA presenter
|
||
paths, whose JS render code is not unit-tested — hence the cross-frontier code review.
|
||
|
||
## Review focus (for the heid panel)
|
||
|
||
1. **INV-004 escaping** in every new render path — the un-unit-tested surface; the exact
|
||
class of bug (`renderPersonaPane` fabricating a Tier-1 field) that only a cross-model
|
||
review caught on #18 D2.
|
||
2. **INV-ADMIN-KEY** — confirm the admin key never reaches a response body or the browser.
|
||
3. **AdminEvents SSE proxy** (`_admin_events_endpoint`) — generator/filter/lifecycle: fixed
|
||
event name, server-side filter, `stream_error` on failure, `aclose()` on every path,
|
||
`CancelledError` re-raise on disconnect.
|
||
4. **PAD-poll** stop-condition — does `emitted_at` advancement + the `state.turnId` guard
|
||
correctly stop the poll without racing or leaking timers?
|
||
5. **Reasoning indicator** lifecycle — shown on first `thinking`, removed on first `text`
|
||
or terminal, interval cleared (no leaked `setInterval`), name via `textContent`.
