Bring the interception-seams branch onto current master (via A→B). The substantive reconciliation is master's compaction `agent/pre-step` serial seam meeting C's interception seams: - types.ts: keep BOTH master's `agent/pre-step` AND C's new interception events (`agent/prompt-submit`, `agent/session-start`, `agent/turn-continuation`→ `ContinuationDecision`); drop the turn-mirror declarations (removed on A). - loop.ts: the merged per-turn order is `turn/start` → per queued msg `agent/prompt-submit` (rewrite/inject/block) → (fully-blocked ⇒ zero-step `rejected`) → per step: drain steering → assemble system prompt → `agent/pre-step` (compaction, OUTSIDE the step) → `step/start` → single `deriveMessages()` → model → tools/pre-execute·dispatch·post-execute. No turn-mirror emits; `closeTurn()` is the A-simplified single-call form. - Docs (architecture, core.md, agent/agent-loop READMEs, catalog) reconciled to show C's interception seams alongside `agent/pre-step`, no turn/step mirrors. - rfc/README: dropped the stale `proposed/` compaction row (master moved that RFC to implemented/); kept C's new `pre-tool-input-rewrite` proposed row. - interception.spec.ts: migrated its two `agent/turn-end` reason collectors to the `turn/end` session event, and ADDED a cross-test proving a `prompt-submit` rewrite + additionalContext is VISIBLE to an `agent/pre-step` listener on the same turn — pinning the merged seam ordering (compaction sees the post-prompt-submit surface, not stale history).
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) |
subagent-mock/ |
Scripted SubagentProvider for deterministic seam/tool tests |
(registers on ctx.subagents) |
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. subagent-mock exercises the real ctx.subagents load path without a model or child agent. A package graduates OUT of support/ into a product group only when it gains documented product consumers.
