Add the durable session-persistence capability seam (ADR 0016): an
abstract SessionPersistence service (dsh-session-persistence,
ctx.sessionPersistence) defining create/append/load/list/has/delete/
update over the existing SessionEvent — no parallel persisted type — and
a first implementation (dsh-session-persistence-jsonl): an append-only
JSONL log per session with crash-safe atomic writes, truncation-repair
of a never-committed crash tail, and a read/replay path. SessionMeta
(format version, cwd, lineage) travels out-of-log via session.header.
A shared runPersistenceContract suite holds every backend to the same
append-only / contiguous-seq / lazy-materialization / serializability
semantics.
Config-driven create() now uses a per-run ${id}-session-<uuid> session
id so a fixed name no longer collides with an on-disk log once a durable
backend is loaded; each run is a new session (a demo simplification). The
examples drop their hand-rolled session-jsonl.ts and load the JSONL
backend via cordis.yml; CI smoke-loads it too.
The agent-facing create/resume factory that consumes load() is a
separate seam, deferred to a follow-up; this change stops at the load
primitive and does not reach into the loop.
The doc-sync gates were CI-only, so the AGENTS.md doc-sync promise could be
missed locally until after push. Add a shared `doc-sync` package.json script
(doc-typecheck + verify-event-taxonomy) wired into the lefthook pre-push job,
and point the CI step at the same script — one source of truth per ADR 0007.
Addresses PR review finding.
Two tsx CI gates make doc/code drift fail fast:
- doc-typecheck extracts every fenced ts block from README/docs/package READMEs,
compiles them with tsc --noEmit against a temp project (vendor->lib, harness->src
paths from tsconfig.typecheck.json), and fails on errors. Deliberate sketches opt
out with ```ts ignore-check; the opt-out ratio is reported and capped.
- verify-event-taxonomy asserts the docs/architecture.md taxonomy table names
exactly the events declared in the interface Events blocks. This surfaced three
events the table had been missing (tools/change, llm/adapter-change,
system-prompt/change), now added.
Doc snippets made compilable with stub imports/declares (1 genuine sketch ignored).
Wired into CI after typecheck. API reports (RFC 006 pt 3) deferred. Graduates RFC
006 pts 1-2 -> ADR 0014.
CI failed at Lint with 1519 no-unsafe-* errors on every cross-package
import. Three fresh-checkout issues, invisible locally because lib/
persists between runs:
- Lint ran before Typecheck, but the type-aware ESLint config resolves
vendor packages via their built declarations (tsconfig.typecheck.json
-> vendor/*/lib), which Typecheck emits. Reordered.
- The first-ever tsc -b resolved sibling vendor plugins through their
package.json types (lib/index.d.ts, not yet emitted) — TS2307 until a
second run. The source-level paths map moves from the root
tsconfig.json (dev-only, not inherited by package builds) into
tsconfig.base.json so the whole build graph resolves source-first;
tsconfig.typecheck.json still overrides wholesale to lib resolution.
- Hygiene ran publint (validates packed lib/index.js bundles) before
Build emitted them. Reordered.
Also: checkout/setup-node bumped v4 -> v6 (node20 runners are
force-switched to node24 on 2026-06-16), the Build step name catches up
with tsdown, and AGENTS.md documents the one case where a fresh clone
needs `yarn typecheck` before `yarn lint`.
GitHub Actions on push/PR: immutable install, constraints, lint,
typecheck (src + tests + examples), tests with the per-file 100%
coverage gate, knip + publint, full build, and a demo smoke test that
drives the echo-agent over scripted stdin asserting the tool-call
round-trip and the JSONL session dump — the same commands the local
scripts and git hooks run.
