Slice-5 (characters + me/capabilities/models) done through the full House Code
Discipline, tags v0.21.16–.18, suite 488 green, live-smoke-proven on :8081/b128,
both heid gates cleared. Current state / in-flight advanced to slice-6 (admin) next;
Recent-decisions index entry + detail file added; substrate at v0.21.18.
persistent-memory.md stays ~333 lines (over the ~300 soft cap): the length is
dominated by the non-archivable Current state / in-flight block plus <30-day July
entries (guarded), so archival can't reach the 250 target — left as-is per the
stop-where-the-guards-stop rule.
Panel (Gróa + Hulda + Regin, source-verified by Heid): adapter/route-map/
ConnectFailed-at-call-sites sound against the declared invariants; 4 real
robustness findings, all in the CLI open-world presenter/probe paths — the
container-type layer BELOW the null/element holes the code-review already fixed.
Fixed (findings 1-3):
- `_format_whoami` (`cli.py`): a non-iterable `scopes`/`allowed_roles` scalar
(`{"scopes": 123}`) made `x or []` yield `123` → `for s in 123` TypeError. New
`_display_seq` helper degrades any non-list (scalar / bare string / null / absent)
to empty; applied to both `scopes` and `allowed_roles`.
- `_characters_probe` (`cli.py`): same class on the model catalog `items` (`{"items":
123}`) — now guards `models` is a Mapping and `items` is a list before iterating.
- `_characters_probe`: the top-level open-world reads `created` / `state` are now
`isinstance(_, Mapping)`-guarded before any `.get` — a non-mapping SDK passthrough
(`created=[...]`) aborts cleanly (exit 20) / renders `pad=None` instead of an
AttributeError.
Accepted (finding 4, documented in contract § slice-5 notes): the `--characters`
probe leaks its transient character on a mid-lifecycle failure. PRE-EXISTING (the
retired probe had the identical linear no-`finally` structure — cutover did not
worsen it), TTL-bounded, one-shot diagnostic; a `try/finally` would swallow a
happy-path delete-failure (delete is both teardown and a tested step). Gróa + Heid
concur accept is defensible.
Dismissed (finding 5): Hulda flagged `sessions.py` dropping `get_me`/etc. as a
caller-contract break — it is the intended DEC-3 no-backwards-compat migration (all
in-repo callers rewired same-diff); Heid labels it intended-surface-change.
Added CLI tests for the three hardened paths (scalar scopes/roles; scalar items +
non-mapping state; non-mapping create abort). Suite 488 green; ruff clean; live
smoke re-run clean (identical happy-path output). Patch bump 0.21.17 → 0.21.18.
Panel: Gróa + Regin returned zero (adapter/route-map/error-map faithful);
Hulda flagged two source-confirmed open-world-presenter crash holes — the same
class the slice-4 bug-hunt found in the agents presenters. Both fixed:
- `_format_whoami` scopes (`cli.py`): `', '.join(me.get('scopes', []))` crashes on
a present-null `scopes` (`.get(k, [])` returns None, not the default) or a
non-string element. Now `', '.join(str(s) for s in (me.get('scopes') or []))` —
matching the `allowed_roles` hardening on the same function. The contract names
`_format_whoami` as the degrade-not-crash exemplar (contract:144-146); the cited
exemplar had an un-hardened line.
- `_characters_probe` model items (`cli.py`): the slice-5 `or []` guarded the
list-level null but not each entry — `[None]` / `["x"]` / `[{"name":123}]` would
raise. Now guards each item is a dict and str-coerces `name` (element-level
completion of the list-level guard).
Hulda #3 (live-smoke not in the reviewed file set) → accept: the smoke WAS run and
is recorded in deab762 + coverage-map (artifact-only review couldn't see it).
Added CLI tests for both hardened paths (present-null/non-string scopes; malformed
model items). Suite 485 green; ruff clean; live smoke re-run clean (identical
happy-path output). Patch bump 0.21.16 → 0.21.17.
Slice-5 of the worldtree-sdk cutover: migrate the remaining consumer READS +
transient-character CRUD off the hand-rolled httpx wrappers onto the
`ratatoskr.wt` adapter over the SDK, and delete the retired path.
Adapter (`wt.py`): add `get_me` / `get_capabilities` / `list_character_models`
/ `create_character` / `get_character_state` / `delete_character` over
`client.me` / `client.capabilities` / `client.models` / `client.characters.*`.
All six are open-world reads/acks returned verbatim; none carries a
discriminated SDK error, so each maps any `ApiError` → the `SessionApiFailed`
default (INV-CUT-2) — exact parity with the retired path. No new Error-map rows.
Decisions (contract § slice-5 notes): `create_character` omits `state` when None
(SDK-idiomatic inline literal, server-equivalent to the retired explicit null);
`delete_character` returns the SDK's open ACK verbatim (`-> Mapping|None`, not
normalized to None).
CLI rewire (`cli.py`): `--whoami` (me + capabilities) and `--characters`
(models → create → state → delete) build a `wt.build_client` over the injected
probe transport and catch `wt.SessionApiFailed` + `ConnectFailed`. Open-world
degrade-not-crash carried (cumulative cutover foot-gun): `_characters_probe`
reads `items` null-safe and extracts `character_id` defensively (clean abort,
no hard-index KeyError); `_format_whoami` widened to `Mapping`.
Deleted the six hand-rolled `sessions.py` wrappers (net -5 mypy no-any-return);
`endpoint_for_plane` + `get_session_bifrost` (slice-6) + the exception classes
stay. Retired the corresponding `test_sessions.py` classes; added the slice-5
adapter tests + a CLI malformed-create-abort test.
LIVE SMOKE (:8081, b128) — INV-CUT-5 / DEC-4 cleared: `--whoami` rendered real
identity + capabilities; `--characters` drove the full lifecycle end-to-end
(char-rp catalog → created char_8c00006e… → PAD read-back → deleted).
Suite 483 green; ruff clean; mypy at the 2 pre-existing baseline errors.
Patch bump 0.21.15 → 0.21.16 (the cutover MINOR is deferred to slice-7, DEC-6).
Panel (Gróa+Hulda+Regin, 5/5/5, no false positives) confirmed two 3/3 crash
sites where open-world dict reads violate the declared "degrade, never crash the
presenter" invariant — the wt adapter tests + the live smoke used full server
dicts, so partial/drifted wire responses were never exercised:
- FIX (tier3.py _run_define/_run_patch): the CLI hard-indexed the open-world
define/patch dicts (`info["agent_id"]` / `["role"]` / `["agent_name"]`), so a
partial 2xx → KeyError escaping main()'s exit matrix as a raw traceback (exit 1);
and `make_description(info.get("system_prompt", ""))` fed None to .splitlines()
on a present-but-null field → AttributeError. Now reads via `_str_field` (absent/
null/non-str → default), degrades role to '?', indexes only a well-formed identity,
and maps a no-usable-agent_id 2xx to [api_failed] exit 20 (controlled, not a crash).
- FIX (web/server.py _agents_endpoint): the upstream dedup hard-indexed each item
(`{a["agent_id"] for a in upstream}` + `_as_dict`), so a malformed item (`[{}]`,
`["str"]`, `{"name":…}`, non-str agent_id) or a non-list envelope → 500 before the
local fallback merged. Now filters to well-formed mappings first; a non-list
upstream degrades to the local-only list.
- FIX (wt.py _error_field_from_body): type-check the parsed `field` is a str (the
exception surface is `field: str | None`, the CLI prints it) — restores the retired
hand-rolled `_extract_error_field` isinstance guard.
Held (triaged, no change): the 429→Tier3QuotaExceeded / bare-404→Tier3AgentNotFound
maps are ungated-by-error_code BY CONTRACT DESIGN (§ Error map route+status rows; the
SDK's ApiError floor drops Retry-After, so retry_after=0 is canonical) — the arms
flagged them spec-free; Heid's source-check confirmed intended. Dual-keying define's
429 for full row consistency is an available tightening (contract amendment), surfaced
not applied. The persona-endpoint SessionApiFailed gap the arms also caught was
already closed in the prior code-review fixup (aed9429).
Suite 475 green (+5).
Panel (Gróa+Hulda+Regin) returned zero adapter / error-map / model→role drift;
three actionable items triaged as genuine adds:
- FIX: `_persona_state_endpoint` now catches `wt.SessionApiFailed` and returns the
`session_api_failed` envelope with the upstream status, for parity with
`_agents_endpoint` / session-create / admin (2/3 arms flagged it; it was the lone
sibling letting an unmatched upstream ApiError escape as a raw 500). Confirmed
NOT a slice-4 regression — the pre-cutover persona endpoint had the same latent
gap — but closed here since the endpoint's error surface is already being hardened
(it gained the ConnectFailed catch this slice).
- TESTS: dual-key NEGATIVE rows — a wrong error_code at the same status defaults to
SessionApiFailed for `define_agent` (403, 422) and `patch_agent` (422); plus the
flat-`field` body-parse shape for `_error_field_from_body` (only the nested
detail.field form was exercised). Closes the assertion-symmetry gap with the
persona route's existing negative test.
- AMEND: contract slice-4 notes document the intentional client-side `":" in
agent_id` PRE on patch/delete (a Tier-3 id is always <user>:<name>, ADR-0019).
Suite 470 green (+5).
Cut ratatoskr's consumer agent-lifecycle routes over to worldtree-sdk
(issue #20 slice-4). Five routes now flow through `ratatoskr.wt` over the
SDK's `client.agents.*`, returning open-world dicts and mapping the SDK's
undiscriminated `ApiError` floor by route+(status,error_code) per INV-CUT-2:
- `list_agents` → `agents.list`
- `get_persona_state`→ `agents.persona_state` (404 persona_not_configured /
404 agent_not_available / 403 auth_scope_denied)
- `define_agent` → `agents.define` (429→Tier3QuotaExceeded(retry_after=0),
403→Tier3UserIdUnsupported, 422 layer_deferred→…)
- `patch_agent` → `agents.patch` (404→Tier3AgentNotFound, 422 field_not_mutable)
- `delete_agent` → `agents.delete` (404→Tier3AgentNotFound; NOT hide-existence)
Rewired call-sites: the `python -m ratatoskr.tier3` CLI (define/patch/delete)
and the web `_agents_endpoint` / `_persona_state_endpoint`, both catching the
SDK's `ConnectFailed` transport-failure normalization. Deleted the hand-rolled
paths: `sessions.list_agents` / `get_persona_state` / `AgentInfo`, and
`tier3.define/patch/delete_agent` / `Tier3AgentInfo` / parse+extract helpers.
model→role fold (scope B): the define/patch response echoes `role` (spec 1.2 /
b128), read off the open-world dict; `LocalAgentEntry.model`→`.role`,
local-index schema v1→2 (old index discarded, no-backwards-compat).
The Tier-3 caller-semantic exceptions move to `sessions.py`: running the CLI
as `__main__` while `wt` imports `ratatoskr.tier3` bound two copies of each
exception class, so a raised `Tier3AgentNotFound` escaped the CLI's `except`
as an uncaught traceback. Homing them in `sessions` (never `__main__`) makes
the class identity single. The live smoke — not the unit tests, which call
`main()` in-process — caught this.
Error-map rows + slice-4 notes added to the cutover contract; coverage-map
re-anchored. LIVE-SMOKE on personal :8081 (b128): define(thoughtful-character)
→ patch → list(6 agents) → persona_state(→PersonaNotConfigured mapped) →
delete → index empty; non-existent-id patch via `-m` → [agent_not_found]
exit 20. Suite 465 green.
The slice-3 heid-bug-hunt panel (3/3) caught a real regression the cutover
introduced, plus a chokepoint-invariant gap:
- ConnectFailed escaped both rewired CLI probes. When --set-persona-pad and
--seed-first-message moved off raw httpx onto the wt adapter, transport failures
changed class: the SDK normalizes any pre-response transport error to
worldtree_sdk.ConnectFailed (request.py), a WorldtreeError (not ApiError), so it
passed the adapter unmapped AND the probes' httpx-only except tuples → an uncaught
traceback instead of the graceful [network_error] exit 21. _amain (slice-2) already
handled it; the probes lagged. Fix: add ConnectFailed to both probe except tuples
(mirrors _amain). Live-verified at a refused host → [network_error] exit 21.
- Finite-PAD enforced only at the CLI, not the adapter chokepoint. wt.set_persona_state
delegated finiteness to the caller (documented), so a direct/non-CLI caller passing
nan/inf got a raw SDK ConfigurationError. Fix: assert finiteness in the adapter
precondition (consistent with its other precondition asserts) so the invariant holds
at the chokepoint in ratatoskr's own terms; the CLI pre-check stays for the friendly
usage error.
Triaged-and-declined (all correct per the panel + Heid's source-check): the deleted
sessions.py exports (intended no-shim cutover, zero un-migrated importers), the
session["session_id"] index (accept-known-risk, matches --new), and Regin's "web
indefinite block" (refuted — the seed is asyncio.wait_for-bounded). The concurrent
heid-code-review panel returned zero drift, no code change.
TDD: 3 RED tests (both probes' ConnectFailed → exit 21; adapter nan/inf/-inf →
AssertionError, never reaches the SDK) → GREEN. Suite 469; ruff clean; mypy no new errors.
Slice-3 of the worldtree-sdk cutover: migrate the session persona-state write,
the #347 authored-history write, and get_session_messages onto ratatoskr.wt, and
route the first-message preset seed through the adapter. Retire the last
hand-rolled sessions.py paths the --seed-first-message probe kept alive
(create_session + SessionInfo, set_persona_state, write_authored_history,
get_session_messages, _bifrost_error_from).
- wt.set_persona_state (SDK PadState) — the CLI passes three finite PAD axes; the
SDK owns the {"pad": {...}} wire (#317). No route-specific error row → the
SessionApiFailed default.
- wt.write_authored_history (SDK write_history) — v1 author=assistant; 404 →
AuthoredHistoryUnavailable (hide-existence; the route is the discriminator,
never the body); every other ApiError → the default. Drops the unused
author/effects/claimed_original_at params (no caller uses them).
- first_message.seed_preset_first_message now takes a WorldtreeClient and routes
through wt.write_authored_history; the best-effort invariants (INV-001..004,
never-raise/never-block/one-write/zero-worldtree-source-import) are unchanged.
Tests drive a fake WorldtreeClient — the wire is the SDK's to prove.
- CLI --set-persona-pad / --seed-first-message + the _amain and web create-path
first-message seeds rewired onto the adapter. --set-persona-pad pre-validates
PAD finiteness (clean usage_error, never a crash on the SDK ConfigurationError).
LIVE-SMOKE on personal :8081 (b128, INV-CUT-5): --seed-first-message → 201
(seq=0, phase=seeded) → read-back verbatim; --set-persona-pad → 204; the --new
create-path preset seed observed routing through the adapter. All slice-3 route
families proven end-to-end through the ratatoskr surface.
docs/coverage-map.md + first_message.contract.md re-anchored onto the adapter;
the slice-2 create/stream/cancel rows re-anchored too (they still named the
deleted sse_client/sessions symbols).
Suite 466 green; mypy no new errors (baseline 22 → 20 in the touched modules);
ruff clean. INV-CUT-1..5 held. Bifrost provider planes untouched.
Slice-2 (sessions/turn) done end-to-end through the House Code Discipline; both heid
gates triaged+fixed. Captures the KEY ADAPTER FACTS foot-guns for slices 3-7 (open-world
dicts, body-derived turn_id, ConnectFailed(0) transport normalization, consumer_key
bound-only, nested-detail error_code parsing) + the two-lens gate value proof. Slice-3
(persona/authored-history) next.
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.
Triaged the heid-code-review panel (Gróa + Hulda substantive, Regin zero=weak).
Adopted (genuine adds):
- cancel_turn + stream_turn gain a defensive `except ApiError -> SessionApiFailed`
default after their discriminated branches. INV-CUT-2 ("every ApiError is mapped;
default SessionApiFailed") now holds STRUCTURALLY on those routes, not by coupling
to the SDK's internal guarantee that it maps them to discriminated types. + tests.
- get_session_tools error-path test (symmetric with messages).
- Contract § Error map amended: added the stream ProtocolError rows
(Malformed*/TurnIdFlip -> ratatoskr same-named), clarified the cancel row (the SDK
RAISES the typed races -> ratatoskr exceptions, only a 200/cancelled=False is a
CancelResult; caller surface stays exception-based per DEC-2), and noted the
ApiError default holds on stream+cancel too.
Rejected (category-5, wrong-grounding) — 2/3 arms flagged create's bound-502 as
"should gate on error_code like list's 422+cursor_invalid". Verified against the SDK
parser (not in the arms' file set): the bound-502 body is
{"error_code":"bifrost_handshake_failed","detail":{"bifrost_error":...}}, and the
SDK's envelope parser PREFERS the nested detail (which lacks error_code), so
ApiError.error_code resolves to "unknown" — gating would REGRESS handshake detection
(the cli/web integration tests caught it). INV-002 also makes the handshake the sole
bound-502 cause. Kept the any-bound-502 mapping; documented WHY in code + contract.
Accepted-as-is: create_session -> Mapping annotation (intentional open-world
passthrough, already documented in the route-map note; category 3).
Suite 493 green; wt.py mypy + ruff clean. Patch.
DEC-4 live smoke PASSED first (personal :8081, b127/b128): create → streamed turn
that rendered (worker_phase/text/text_boundary/done with usage) → SIGINT cancel that
round-tripped to a cancelled terminal. With both CLI + web on the adapter, the
hand-rolled turn-stream family is fully orphaned — deleting it now.
- sse_client.py (714 → 224): removed stream_turn / reconnect_turn /
stream_turn_resilient / cancel_turn + the Event dataclasses (Text/Done/…/Event
union) + CancelResult + the SSE parse helpers (_iter_events / _envelope_for_type /
_parse_sse_id / _eager_failure_fields / _INT_RE). KEPT: the caller-semantic
exceptions (the adapter raises them, DEC-2), SseId, AdminEvent, stream_admin_events
(slice-6 admin surface).
- sessions.py (677 → 608): removed list_sessions + get_session_tools (no surface
users) + SessionPage. KEPT: create_session / get_session_messages (the
--seed-first-message probe still uses them, slice-3) + all exceptions + SessionInfo.
- tests: test_sse_client pruned to TestStreamAdminEvents; test_sessions dropped the
list_sessions + get_session_tools classes. The deleted turn-stream behavior is now
covered by test_wt.py + the CLI/web integration tests + the live smoke.
Suite 490 green (570 − 80 deleted turn-stream tests); ruff clean on all touched
files; no new mypy errors. Patch (internal cleanup; behavior preserved).
The Starlette endpoints (create / stream / cancel / tools / messages) now go through
ratatoskr.wt over the worldtree-sdk; the browser contract is preserved. This is the
last consumer of the hand-rolled turn-stream family — after this, stream_turn* /
cancel_turn are orphaned and get deleted in part 2b-iii (with the live smoke).
- _wt_client wraps a client_factory transport as the adapter's WorldtreeClient
(INV-CUT-1), reading base_url + bearer off the transport (a no-auth test transport
falls back to a placeholder key). The hand-rolled endpoints (persona / agents /
admin / bifrost) keep using the raw transport until their slices.
- _event_to_browser_payload derives the browser payload from the SDK's `raw` (the
wire body) minus the redundant `type`, plus the composite `sse_id` string — the
SAME shape the old dataclasses produced, so the presentation fixture + browser JS
are unchanged; the browser event_type is the wire `type`, not the SDK class name.
- The stream endpoint captures the upstream cancel target from the composite sse_id
(the SDK's top-level turn_id is body-derived, absent on text frames); create reads
the SDK's open create dict; cancel reads CancelResult.cancelled and surfaces a
generic 502 for CancelFailed (the SDK abstracts the upstream cancel HTTP status).
- test_web_presentation_contract builds SDK events via build_event; two cancel tests
adopt the SDK's (status, error_code) race pairs + the 502.
Suite 570 green; web/server.py + presentation test ruff-clean, mypy unchanged
(same pre-existing errors). Patch (internal; browser contract preserved).
The --send turn path (_amain create + _run_turn stream + _cancel_and_log) now goes
through ratatoskr.wt over the worldtree-sdk; external CLI behavior (output, exit
codes) is preserved. No hand-rolled path is deleted yet — web/server.py still uses
them (part 2b-ii), so the deletions + live smoke come after web is rewired.
- _amain builds one WorldtreeClient via wt.build_client over a ratatoskr-owned
transport (INV-CUT-1); create → wt.create_session (reads the SDK's open create
dict); the transport keeps the default bearer so the not-yet-migrated hand-rolled
seed_preset_first_message (slice-3) still authenticates.
- _run_turn drives wt.stream_turn and consumes SDK TurnEvents; the mid-stream cancel
target is parsed from the composite sse_id ("{turn}:{seq}") — the SDK's top-level
turn_id is the body field and is absent on text/thinking frames.
- CliPresenterState.render consumes the SDK TurnEvent union with None-hardening on
the now-optional fields (usage degrades to "(n/a)" rather than crashing).
- The SDK normalizes a pre-response transport failure to ConnectFailed(status=0);
_amain (network → exit 21) and _cancel_and_log (swallow, INV-009) catch it.
- build_client gains max_reconnects (SDK default 5; tests pass 0 to surface drops
immediately). test_cli: SDK-event factories keep the render-test bodies intact;
client constructions wrap in build_client; cancel-race mocks carry the SDK's
(status, error_code) pair.
Suite 570 green; cli.py + wt.py mypy + ruff clean (the pre-existing send_content
arg-type note is unchanged). Patch (internal; external CLI behavior preserved).
Completes the adapter's session/turn surface, still additive and non-breaking (no
surface rewired, no hand-rolled path deleted — the cli/web rewire + deletions +
live smoke are part 2b).
- stream_turn: drives the SDK's resilient stream (auto-resume absorbs the old
reconnect_turn) and yields SDK TurnEvents, re-wrapping the stream's TERMINAL SDK
errors into ratatoskr's caller-semantic exceptions per DEC-2 (SessionRetired →
SessionApiFailed; AgentNotAvailable / TurnLaunchUnavailable / MalformedSse* /
TurnIdFlip → ratatoskr's same-named types; ConnectionDropped → SseConnectionDropped;
ConnectFailed / terminal ResumeError → SseConnectFailed). The presenter keeps
catching ratatoskr types (part 2b aligns the except clauses).
- cancel_turn: returns the SDK CancelResult (a 200 cancelled=False is the benign
late-cancel race, B-CAN-3), mapping the typed cancel races onto ratatoskr's
CancelTurnNotFound / CancelAlreadyCompleted / CancelFailed.
- SseConnectionDropped.last_seen_sse_id widened to SseId | str | None: the SDK's
resume cursor is a raw composite-id str (the cutover's target form); the
hand-rolled path's SseId stays accepted until it is deleted. The one live reader
(stream_turn_resilient) generalizes cleanly — a str cursor is already the id.
Suite 570 green (555 + 15); wt.py + sse_client.py mypy + ruff clean. Patch.
First slice-2 increment: the presenter-independent sessions routes, additive and
non-breaking (no surface rewired, no hand-rolled path deleted yet — the cli/web
rewire + deletions + live smoke land in part 2).
- create_session / list_sessions / get_session_messages / get_session_tools over
WorldtreeClient.sessions.*, each building the request from ratatoskr's domain
params and mapping the SDK's ApiError floor by ROUTE (INV-CUT-2): create 404 →
AgentNotFound, bound 502 → BifrostHandshakeFailed, list 422 cursor_invalid →
InvalidCursor, else the SessionApiFailed default.
- Open-world reads returned VERBATIM (parity-pass posture): the routes return the
SDK's open dicts, not ratatoskr's typed SessionInfo/SessionPage — those typed
result shapes retire when the presenters are rewired to read mappings (adopt the
dep's canonical open-world way, reference-impl doctrine).
- Transitional: wt imports the caller-semantic exceptions + BifrostBinding from the
retiring sessions module (one-way, no cycle); they relocate into the adapter as
their call-sites are rewired.
- Cancel + the resilient turn STREAM are deferred to part 2, where they wire into
the async presenter loop and are validated by the live smoke.
Suite 555 green (541 + 14); mypy strict + ruff clean. Patch (internal, additive).
Slice-1 of the SDK cutover (docs/contracts/worldtree_sdk_cutover.contract.md):
the adapter chokepoint onto worldtree-sdk 1.0.0, unit-tested but not yet wired
to any surface (that is slice-2).
- build_client(base_url, *, api_key, admin_key=None, transport) constructs the
single WorldtreeClient over a ratatoskr-owned injected httpx.AsyncClient.
INV-CUT-1: the SDK is given the transport (_owns_client=False) and never closes
it — proven by a test asserting aclose() leaves ratatoskr's transport open.
- translate_error implements the § Error map DEFAULT: SDK ApiError → the adapter's
SessionApiFailed (carrying the SDK's parsed status/error_code/body); every
discriminated WorldtreeError subclass passes through by identity. Route-specific
rows land at their call-sites in later slices (the route is the discriminator).
- SessionApiFailed gains error_code vs the retiring sessions.py copy (extends it
per the contract error-map row); the two coexist transiently and reconcile in
slice-2 (DEC-4 incremental cutover — nothing wires the adapter this slice, so
they never meet at runtime).
Deletes no hand-rolled path, so DEC-4's live-smoke bar does not apply yet.
Suite 541 green (534 + 7 new); mypy + ruff clean. Patch (internal foundation;
the cutover's minor bump is DEC-6 at slice-7 ship).
Re-snapshot for fresh context. Cutover slice-1 half-landed: worldtree-sdk==1.0.0
integrated + DEC-5 install-verified + committed (29c4fda), suite 534 green; the
ratatoskr.wt adapter (auth/transport split, error-map default) is the next step.
Substrate: unpushed cutover chain (e45640c contract, snapshot, 29c4fda dep) noted;
origin still at b1fbadd. Handoff aimed at the adapter. Index ~19 over soft cap;
archival deferred (guard-protected recents leave little to move — next run.)
Add the worldtree-sdk (Python) 1.0.0 consumer client to core deps + the gitea uv
source (reuses the existing bifrost gitea-index auth). DEC-5 precondition met: uv
resolves + installs it from the registry; WorldtreeClient constructs with an
injected httpx.AsyncClient and _owns_client=False (INV-CUT-1 transport ownership
confirmed live). httpx-sse retained until slice-7 teardown. Full suite 534 green —
the dep is inert until ratatoskr.wt wires it (next).
No version bump (dependency add, no runtime code consumes it yet). Refs #20.
Captures the SDK cutover as the active migration: contract done + heid-reviewed,
DEC-5 registry gate cleared, slice-1 foundation the next step. Plus ephemeral-Echo
(v0.21.2 #19) + reference-consumer parity arc in Recent decisions; tier3 model→role
deferred to slice-4 / worldtree-dev deploy flag. Handoff written for slice-1.
worldtree-sdk v1.0.0 (wtsdk-dev, althing 01KXVF24WQD2T5ZCS49KKFCCMH) ratifies the
same 41-op surface from the identical OpenAPI 2.3.0 (sha 36148179601453a0) this
ledger already tracks — record it as the external parity authority. Ratatoskr is
the parallel Python/httpx reference-consumer (no TS adoption); the forthcoming
worldtree-sdk Python spine is the future consumable, noted as a repin candidate.
Fold in v0.21.2: POST /sessions row now notes ephemeral-Echo config passthrough
(role not model, W-4 cross-validated by the SDK); GET /capabilities row notes the
--whoami allowed_roles/default_role fix + spec v1.1. REST count unchanged (19/41 —
ephemeral is a depth enhancement to an already-covered route).
No version bump (docs-only coverage-ledger update).
create_session could only mint foundational sessions; an ephemeral template
(agent_id="echo") returned 422 ephemeral_requires_config because ratatoskr never
sent the required config block — Echo was uncreatable, surfacing as an opaque
session_api_failed at the CLI. Thread an opaque, role/model-agnostic config
passthrough through the create path so Echo sessions are creatable.
- sessions.py: create_session(config=...) verbatim passthrough (PRE-004 Mapping /
PRE-005 config-xor-bifrost guards); SessionInfo gains kind + config, captured
defensively (.get) on both create and list.
- cli.py: --system-prompt flag builds config={"system_prompt": ...} (validation:
non-empty, requires --new+--agent, xor bifrost); _amain surfaces kind=; the
--whoami renderer now reads allowed_roles/default_role (was reading the dead
allowed_models/default_model) and tolerates a malformed capabilities shape.
- contract #2 amended (Amendment 2026-07-18); Heid-panel contract-reviewed +
diff-scoped bug-hunted (one whoami null-join gap found + fixed).
Canonical grounding: config.role, never config.model (worldtree-dev althing
01KXT976NN91DRBZBPXNZ2BVZR; ADR-0012 role cutover). Verified end-to-end against
the live v0.16.2 target. TDD across create + CLI; full suite green (534).
Closes#19.
Pull Worldtree main's role/model-cutover doc correction (worldtree commit
b4a278c) into the pinned conversation-api-spec: the Echo ephemeral-template
section now documents allowed_roles/default_role, config.role (omitted ->
default_role "echo"), the repurposed model_not_allowed (any non-empty
config.model hard-rejects), and the new role_required error. Frozen OpenAPI
untouched. affect-egress-consumer-reference re-synced in the same pass;
re-pin hashes in .corviduo-canonicals.toml.
Resolves the role<->model drift ratatoskr-dev raised on althing (thread
01KXT976NN91DRBZBPXNZ2BVZR); worldtree-dev cleared the re-sync.
No version bump (vendored-canonical docs sync).
Refresh vendored soong-lab-bundle canonical copies against upstream and
re-pin hashes in .corviduo-canonicals.toml.
- export: open_question B resolved — the 4 role labels map 1:1 to WT
model-role slugs by exact name (assistant/thoughtful-assistant under
the `foundational` grant, character/thoughtful-character under
`character`), so ship.native.role is directly define-valid. Also,
motivational goals/fears are now structured objects (WT #187) with
id/type/salience/description and validate_exportable gates
(description >=20, type in GOAL_TYPES, salience in [0,1]).
- importer: adds _coerce_goal/_coerce_fear totality path (INV-I-6) with
legacy bare-string back-compat and strict re-validate (no silent loss).
No ratatoskr code impact: the motivational Tier-3 layer is schema-deferred
(Phase 2.0 baseline-only) and no goals/fears string-consumers exist. No
version bump (vendored-canonical docs sync, skip-the-bump per SemVer).
Operator ruled: no arbo fork, no SillyTavern-on-Rata; both app products move to
a new repo (template-dev standing up). Rata does NOT fork and reverts to its core
(Worldtree debug surface + Bifrost reference impl + Conversation-API SDK #371
seed/future-consumer). Retires the 2026-07-17 fork-Rata-for-arbo NEXT-MAJOR plan;
resolves the arbo-vs-SDK open question the prior snapshot flagged.
Capture this session's durable state: the "fork Rata for a SillyTavern-style
app?" question resolved to don't-fork — Worldtree owns an official Conversation
API SDK (WT #371), seeded from Rata's client spine; the app is a fresh TS
sibling. New Current-state thread + Recent-decisions entries + a full-arc detail
file; arbo-fork decision preserved with the arbo-vs-SDK priority flagged as an
open operator question. Auto-archived 35 settled 2026-06-14..06-18 entries
(19 Recent, 16 Tried) to archival-memory.md. Handoff refreshed.
Add awaiting_llm_first_token (#201) and affect_update (#204) to issue #1's
Event union and TESTS via a dated amendment. Both events are parsed by
_envelope_for_type and covered in tests/test_sse_client.py, but issue #1's
Output union + full_event_vocab test were frozen at the v0.19.0 baseline's
8-event set — contract-vs-code drift surfaced during the Worldtree #371 SDK
parity-matrix pass. Documentation-only: no code change, no version bump.
Move the consolidated #368 in-flight narrative (diagnosis -> two-channel
investigation -> both scrubs -> marker repro -> enforcement read) out of
persistent-memory.md Current state into the silo-test detail file, leaving
a compact pointer. Index 439 -> 339 lines.
- #368 (user,character) memory silo test DONE + PASSED live (WT b127):
write-side conjunctive {end_user,agent_self} scoping + read-side cross-
character isolation both proven end-to-end; betty (throwaway) deleted,
Sindra intact. Full record in persistent-memory.d/2026-07-18-368-silo-
test-passed.md. Retired the stale "silo test in progress" in-flight blocks.
- Two-tier migration: split 152 over-threshold dated entries into
persistent-memory.d/ detail files, leaving one-line pointers in the index
(startup load ~196KB -> ~53KB; bodies now load on demand).
- Tier-3 stores scrubbed clean (memory 0 / affect 0, provider restarted
empty); persistent-memory + detail file updated to reflect the scrub.
Current state now leads with the (user,character) memory silo test:
store born-fresh, throwaway betty ready, Sindra off-limits, waiting on
WT #368 fix deploy. tier3 CLI fixed (v0.21.1). Handoff written for the
post-clear session.
Live Worldtree b125 changed POST /agents/define: the request field is
now 'role' (a model-role like 'thoughtful-character'), replacing 'model';
the response still echoes it as 'model'. Update define_agent/patch_agent
request bodies + CLI (--model -> --role); response parse + LocalAgentEntry
unchanged. Verified end-to-end against live (delete->define round-trip);
26 tier3 tests green. Full b22->b125 spec-pin bump remains a follow-up.
Re-scrubbed store born-fresh; created throwaway ratatoskr:betty for the
Alice/Betty silo demo (MUST delete after; Sindra off-limits). Found
tier3 CLI drift vs live b125 (/agents/define now needs role not model).
Test runs post WT-fix-deploy: Sindra coffee / Betty tea -> verify silo.
WT folded F1/F2/F3 into contract rev 1.3 (3e3f629) with new tests each;
our read-path conformance cited. Backfill live-verify (synthetic legacy
corpus, pre-flip) queued for when the backfill lands. #368 done from
ratatoskr's side end to end.
Fresh Sindra session promoted the rhodochrosite marker to our store
scoped {end_user}-only (chunk 647aeac6) = pre-fix channel-1 baseline.
WT correction: consumer agents write only to our store (no server-side
chroma); Sindra IS Bifrost-attached unlike foundational Lofn. Decisive
server-side grep still pending. ETA: contract to us today, ship ~7/19.
Operator ruled full memory scrub both sides. Our memory.db wiped to 0
chunks, :8392 restarted born-empty (no backup, direct go); Sindra
pristine-baseline note marked obsolete. Marker repro (rhodochrosite,
fresh Sindra session) queued for after both scrubs confirmed; personal
is b125; current Lofn chunks are the feedback loop, mis-write unproven.
GET /search proves the name was introduced ONLY to Sindra, ZERO to
Lofn (0 user msgs across all Lofn sessions), yet Lofn recites it —
incl. a pre-existing session predating my captures. Cross-agent leak
via WT person-prime (#349), agent-axis-less query. Missing agent-axis
is channel-2's load-bearing fix. Rev 1.2 contract inbound for our read.
Both fresh Lofn turns (direct + combined) recited the name with a
bifrost handshake but ZERO memory-calls to us. Turn-context bleed never
traverses our Tier-3 retrieval; it's WT-internal assembly. Two channels:
Tier-3 semantic recall (our provider, closed by conjunctive scope_any)
+ WT-internal (active turn-context path, WT-side fix). Exhibits pinned to #368.
Operator ruled Option 1; no amnesia cliff (backfill from agent_id
metadata). Confirmed our _scope_subset enforces conjunctive scope_any
(fix rides scope_any alone). Labeled Lofn capture recites the name;
direct-bind turn got it WITHOUT querying our store -> WT-internal read
path also in play. ratatoskr is the enforcement half; contract inbound.
The textual TUI (tui.py) is superseded by the web console (ratatoskr-web)
and is removed per the no-backwards-compat rule. The `ratatoskr` command
stays as a headless client: --send / --whoami / --characters /
--set-persona-pad / --seed-first-message still work; invoking it with no
--send now returns a usage error (rc 10) instead of launching the TUI.
Removed: src/ratatoskr/tui.py, tests/test_tui.py, the textual + textual-dev
deps, and cli.py's run_tui launch path. cli.py's shared exports (USER_AGENT,
ParsedArgs, formatters) stay — web/entrypoint.py and tier3.py depend on them.
BREAKING CHANGE: the interactive `ratatoskr --agent X` TUI is gone; use the
web console (ratatoskr-web) for interactive debugging, or --send for scripted.
Verified: full suite 520 passed; ratatoskr --help exit 0; no-send -> rc 10;
web/provider/tier3 import clean; textual absent from the lockfile.
Each debug pane (#rail-left, #affect-console) gains an independent
collapse control: a chevron button in the pane header folds it to a
22px re-open strip, and #center (flex:1) reflows to fill. State
persists per-pane in localStorage (ratatoskr-left-collapsed /
-right-collapsed), matching the theme/cot-toggle idiom; the right-side
drag-resizer hides with its pane. Collapsing both yields a clean
chat-only surface.
Playwright-verified end-to-end (default-open, collapse-to-strip,
center reflow, independent left/right, reload persistence, re-open).
Operator UX asks on the web console:
- Code blocks now WRAP (`white-space: pre-wrap; overflow-wrap: anywhere`) instead of
overflowing with a horizontal scrollbar — a long unbreakable token wraps in place.
- Per-code-block copy button (hover-revealed, top-right of each `.md-code-wrap`).
- Per-turn copy button (in the live turn-rule; top-right on seeded/historical turns) —
copies the turn's response text; the existing think-inline copy is unchanged.
One delegated click handler on #tw covers both (works across live / historical / think
renders where blocks are injected via innerHTML). `copyText` falls back to a hidden
textarea + execCommand when `navigator.clipboard` is absent (plain-http LAN context),
and buttons flash "✓ copied". Static file served from disk — a browser refresh picks it
up, no :8765 restart. Playwright-verified: code wraps (no x-overflow), both buttons copy
the right text; 90 web tests green.
