…dency OpenCode 1.2+ moved its sessions to a SQLite store at `~/.local/share/opencode/opencode.db`. The previous reader required `better-sqlite3`, whose prebuilt-tarball + node-gyp fallback chain broke `npm install` on Windows and restricted networks, so it was reverted in 0.6.0-beta.4 and the adapter left as a silent no-op. This restores the reader on the zero-dependency read-only SQLite parser that already ships in core (`internal/sqlite-readonly.ts`, unchanged here). No native module, no WASM, no install-time build step, so the regression that caused the revert cannot come back. - name-matched schema validation, so a future OpenCode layout change degrades to a structured warning instead of malformed rows - WAL-consistent snapshots; the database is opened read-only and is byte-identical after a read - `parent_id` child-session merging for `--include-children` - `mem.ts` drops the "reader unavailable" notice, which is false once the reader works; warning presentation stays a CLI concern Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Pull request overview
Restores a functional OpenCode persisted-session reader in @mindfoldhq/trellis-core/mem using the existing zero-dependency read-only SQLite parser, and wires warning propagation + CLI presentation so OpenCode sessions can be listed/searched/extracted again without any native/WASM dependency.
Changes:
- Replaced the degraded OpenCode adapter no-op with a real read-only SQLite-backed implementation (schema validation, WAL snapshot handling, parent/child session metadata, compaction markers).
- Added OpenCode path resolution (
opencodeDataDir/opencodeDbPath) and integrated OpenCode warnings + prepared-store lifecycle into mem orchestration. - Updated CLI to remove the now-false “OpenCode reader unavailable” notice and added/expanded core tests for OpenCode behavior (including
--include-childrenmerging).

part.time_createdis used for ordering but isn’t validated against actual decoded rows. Include it in the row-level schema check so missing/renamed columns don’t silently collapse timestamps to 0.
requireRowColumns(parts, PART_TABLE, ["message_id", "data"]);

Slice A of the #534 resplit, per your landing order. Branched off current
main(64e66369), not off the old branch.What this does
packages/core/src/mem/adapters/opencode.tsonmainis still the 34-line silent no-op left behind by thebetter-sqlite3revert. This restores a real reader on the zero-dependency read-only SQLite parser that already ships in core (internal/sqlite-readonly.ts— unchanged here, and byte-identical between this branch andmain, which is what makes the slice self-contained).No native module, no WASM, no install-time build step, so the install-failure regression that forced the revert cannot return.

You listed the

I left it out, because its premise does not hold onmain: upstream'stemplates/opencode/package.jsonstill declares@opencode-ai/plugin, so the existing docstring is accurate there. The fork's "correction" describes the bare{"type": "module"}template produced by the pre-start-gate work — which you excluded from every slice. Applying it here would make the comment wrong. Say the word and I'll add it.Scope hygiene
