Triaged the heid-bug-hunt panel (Gróa 8 / Hulda 6 / Regin 6; Heid source-checked + refuted 2 Regin FPs). The lens pulled real weight — confirmed bugs the conformance review structurally could not see. Confirmed bugs fixed: - SessionRetired (410) stream-open maps to wt.SessionApiFailed, but neither cli _run_turn nor web gen() caught it → crash / dropped SSE stream. Both presenters now catch it (cli → exit 20; web → labeled `event: error`). (Gróa#2) + cli regression test. - cli forwarded consumer_key unconditionally; an UNBOUND create with the env key set would auth as the Bifrost consumer, not the default bearer. Guarded in the adapter (consumer_key only when bifrost is set). (Gróa#4 + Regin#4) + test. - cli _turn_id_from_sse_id crashed on a None/non-str sse_id (web guarded, cli didn't) → now tolerant. (Gróa#1 + Hulda#2) + test. - _cancel_and_log broadened to `except Exception` — after the code-review's ApiError default, a cancel could raise SessionApiFailed it didn't catch, breaking INV-009 (never-raise). (Gróa#3, Heid-endorsed over Regin's refuted mechanism). Open-world degrade-not-crash (contract posture): render hardened — float duration_ms (_format_duration_safe), non-mapping usage/snapshot guards, unknown event type degrades instead of asserting (Gróa#5/#6 + Hulda#3); web _event_to_browser_payload guards a non-mapping `raw` (Hulda#4); web _wt_client bearer extraction is now case-insensitive + whitespace-robust (Hulda#5 + Regin#5). + render-degrade test. Rejected (verified): Regin#1 (httpx IS caught), Regin#2 (wtsdk IS worldtree_sdk), Regin#3 (sse_client.AgentNotAvailable IS caught by SseConnectFailed) — all FPs; Hulda#1 (deleted funcs "break callers") — grep-verified zero callers pre-deletion. Accepted-known-risk: lenient sse_id parse, CancelFailed status=0, async-gen aclose (pre-existing pattern, not a cutover regression). Suite 497 green; wt/cli/web ruff + wt mypy clean. Patch.
Ratatoskr
A Worldtree Conversation API debug console. 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. The interactive surface is the
web console (ratatoskr-web); a headless --send CLI drives scripted smokes.
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 (Worldtree must be running)
# Interactive web console:
ratatoskr-web --host 0.0.0.0 --port 8765
# Headless CLI (scripted smoke):
ratatoskr --send "hello" --new --agent mimir --api-key "$WORLDTREE_API_KEY"
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 a small, fixed surface:
httpx+httpx-sse(network layer)starlette+uvicorn(the web console; thewebextra)- 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.
