Consumer side of Worldtree's #347 authored-history-write (the SillyTavern
first-message primitive), shipped via direct in-session TDD:
- write_authored_history (POST /sessions/{id}/history): v1 author=assistant,
effects=none, per-session idempotency; body server-pinned (AuthoredWriteRequest
extra=forbid) so null effects/claimed_original_at are omitted; 200 replay /
201 fresh both return the AuthoredTurnResponse dict.
- AuthoredHistoryUnavailable: the hide-existence 404 (feature-absent / ungranted
/ session-absent, indistinguishable by design — INV-347-1) raised DISTINCT from
SessionApiFailed so callers branch feature-absent and never capability-probe.
- get_session_messages (GET /sessions/{id}/messages): un-deferred as the seed
read-back — confirms a seed renders as a normal role=assistant turn
(model-invisible provenance).
- --seed-first-message probe: create session -> seed -> read-back; a 404 reports
a benign feature-absent result (exit 0), never a capability-probe.
Contract #2 amended (2 FNs, validated OK). 19 new tests (12 wrapper + 7 cli),
suite 601 green. Coverage-map re-converged: REST 19/41 (the #347 route + the
messages read-back close the one gap the 2.3.0 re-vendor opened).
Live-proof pending the session.history.write grant (requested infra-ops).
v1 coverage-audit remediation P-1: vendor the authoritative machine-
readable artifacts and pin them for drift-checking, advancing the spec
pin from v0.35.16 (f1b59f8) to v1.0.0b2 (5810a26).
- Vendor docs/conversation-api-openapi.json (OpenAPI 2.2.0, 40 path-
groups) + docs/conversation-api-sse-events.schema.json (11 events).
- Pin all three Conversation-API artifacts in .corviduo-canonicals.toml:
OpenAPI + SSE schema as strict drift gates (canonical_drift.py), the
prose markdown as tolerate_drift reference. Drift check green (10/10).
- pyproject: worldtree-spec-rev -> 5810a26, worldtree-version -> v1.0.0b2
(was stale at v0.29.0), pinned-on -> 2026-06-30.
- SPEC-PIN.md: current-pin table + history row + vendored-artifacts list.
- coverage-map.md: P-1 marked remediated; the map now audits a frozen,
diffable target.
The prose markdown is byte-identical to v0.35.16 (last WT edit
2026-05-31); the b2 surface lives only in the OpenAPI. No client-
facing code change (the b2 409/503 + unified error envelope were
already consumed in v0.18.3/.4) -> pin-only, no version bump.
First coverage map — every Worldtree v1-FROZEN I/O point x ratatoskr
status. Anchored on WT's frozen machine-readable artifacts (OpenAPI
2.2.0 = 40 REST path-groups + SSE schema = 11 events + bifrost wire
v0.6), not the stale vendored prose markdown.
- SSE 11/11 and Bifrost provider planes 8/8 covered + live-proven;
client REST 7/40 live, 11 in-scope frontier, 22 excluded-by-design.
- Scope mandate A (operator): v1 done = every frozen point classified
(covered-or-excluded-with-rationale), zero unaccounted; not a
feature-complete client.
- Finding P-1: vendored prose markdown is byte-identical to live WT
but frozen at v0.35.16-era content; b2's surface lives in the
OpenAPI 2.2.0 + SSE-schema JSON we don't vendor. Pin-remediation
pending operator nod.
No version bump (docs-only).
