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.
Ratatoskr
A Worldtree Conversation API debug TUI. Runs up and down Worldtree's API surface — sessions, turns, persona, tools, admin events, Bifrost state — carrying messages between layers. Like the squirrel.
The product is the observability surface; chat is the input mechanism. Devs run Ratatoskr against a local Worldtree to watch a turn flow through every layer of the system, side-by-side, in one terminal.
Status
v0 scaffold. Design locked; implementation hasn't started. The dev team owns the implementation pass.
Read in this order
docs/design-brief.md— the locked design. Read this first. Every architectural decision is recorded with its rationale, the alternatives considered, and (where relevant) the operator's lock-in moment.docs/SPEC-PIN.md— what Worldtree spec version Ratatoskr is built against, where the vendored snapshot lives, and how to bump the pin.docs/conversation-api-spec.md— the vendored Worldtree spec snapshot. Read this to understand the API surface Ratatoskr consumes. Do not import anything from a Worldtree checkout — the boundary is the spec, not the code. Seedocs/design-brief.md§2.CLAUDE.md— Claude Code conventions for this repo (mostly inherited from the Corviduo template).persistent-memory.md— durable intent across context resets. Update as decisions and state evolve.
Quickstart
# 1. Environment
uv venv && source .venv/bin/activate
uv pip install -e ".[dev]"
# 2. Verify the spec pin
cat docs/SPEC-PIN.md # documented Worldtree SHA + bump procedure
# 3. Tests (none yet; scaffold only)
uv run pytest
# 4. Run against a local Worldtree (once implementation lands)
# Worldtree must be running: python -m core.conversation_api

What this repo is NOT
- NOT a polished consumer for Worldtree's end-users — that's the web app.
- NOT a Worldtree admin tool — admin CLI is separate (
sessions_cli.pylives in Worldtree). - NOT a featuretracking shadow of the web app — when the Conversation API surface grows, Ratatoskr does not necessarily grow with it.
- NOT a remote-Worldtree debug client — file-tail surfaces (persona log, server log) assume local-dev posture.
The full negative-clause list lives in docs/design-brief.md §6.
Boundary rule
Ratatoskr depends on three things only:
httpx+httpx-sse(network layer)textual(TUI framework)- Worldtree's published Conversation API spec at the pinned SHA
Hard rule: no imports from a Worldtree checkout. No core.* imports,
no from worldtree.*, no shared models, no submodule of Worldtree. The
spec is the entire surface. Boundary smoke test at tests/test_no_worldtree_imports.py
enforces this in CI.
Version-skew strategy
The dev team is decoupled from Worldtree's dev team. To detect drift when Worldtree changes the API:
- Spec-version pin in
pyproject.toml(worldtree-spec-rev). Bump explicitly; bumps are a tracked action. - Recorded-SSE snapshot tests at
tests/snapshots/. Captured against a live Worldtree; replayed in CI. Re-record after every pin bump. - Conformance smoke test — boots Worldtree via Docker compose in CI, runs a one-turn happy path. Catches integration-level drift.
See docs/SPEC-PIN.md for the bump procedure.
Consumer-side discoveries
If you find a spec gap, ambiguity, or missing-but-needed endpoint while working on Ratatoskr: route the discovery back to worldtree-dev via althing rather than via PR on Worldtree directly. The separate-team boundary is intentional and helps catch spec gaps that an in-tree consumer would paper over.
