Reconciles the session-surface work (surfaceOp/sourceEventSeqs provenance as the sole derivation path) with master's worktree-subagent series (fork-seed boundary + out-of-process subagent backends). Semantic reconciliations beyond the textual auto-merge: - SQLite SCHEMA_VERSION: both sides bumped 2->3. Merged to a single v3 carrying BOTH column families — master's seed_length on `sessions` and surface's source_event_seqs/surface_op on `events`. writeRow + both INSERT sites bind the full set; the schema doc lists all three added columns as the v2->v3 gap. - agent-loop runStep request: master's `sessionId: session.id` and surface's per-append surfaceOp/sourceEventSeqs coexist (different regions). - Fork seed + surface: a fork seeds the child from the parent's LIVE events, which now carry surfaceOp, so the child's surface rebuilds correctly. Verified end-to-end — the subagent-fork replay recalls the inherited "SAFFRON" codeword through the seeded prefix. - Subagent snapshot fixtures (recorded pre-surface) re-enriched via KEYLESS deterministic replay: only surfaceOp/sourceEventSeqs added onto existing recorded lines (matched by seq), no recorded value changed. Not re-recorded against the live API. Gates: typecheck, test (1112), test:snapshot (14), doc-sync, lint, build, hygiene all green.
support/ — dev/test/example infrastructure
Packages that exist to serve development, testing, and the examples rather than to ship as product API. They are real workspace packages (typed, tested, under the coverage gate), but they carry lower compatibility expectations: they may change or be removed when the development need behind them does, without the deprecation care a product package would warrant.
| Package | Role | ctx key |
|---|---|---|
invariants/ |
Dev-mode event-contract invariants + session-log freeze | (listens on session/*, agent/*) |
ui-stdio/ |
Minimal stdio (readline) UI plugin: renders agent/* events, feeds stdin lines to the agent |
(drives ctx.agents) |
llm-replay/ |
Record/replay adapter: short-circuits llm/stream from a recorded session JSONL (keyless snapshot tests) |
(listens on llm/stream) |
invariants runs only in dev mode (contract checks, not runtime behavior). ui-stdio and llm-replay were extracted from the examples for reuse and to bring them under the per-file coverage gate; they back the demos and the snapshot test tier. A package graduates OUT of support/ into a product group only when it gains documented product consumers.
