Crate ocserve_core 

ocserve-core: session domain — event bus, IDs, permission rendezvous, sync prompt runner with the tool loop.

Wire-invisible internals adopt v2 engineering where the plan says so (PLAN §11): durable event seq, bounded ring, crash-recoverable claims land with M3 milestones.

Re-exports

pub use event::EventBus;

pub use permission::PermissionGate;

Modules

compact

Compaction-lite (W3): port of v1 buildPrompt + serialize from packages/core/src/session/compaction.ts + session/compaction.ts (source-derived; no live-mutation probe needed for prompt text).

compaction

M6 compaction engine (COMPACTION.md §2.3/§2.4): create + process.

event

Event bus: byte- AND count-bounded ring with cursor receivers.

ids

Upstream-shaped resource IDs: <prefix>_<26 chars> where the first 10 hex chars encode ms-timestamp LE (matches observed msg_0fa1e3f770014jHIfQNh0Lhiu3).

loop_guard

Loop intelligence (DIFFERENTIATION.md D1 / P1b).

permission

Permission rendezvous: ask → permission.asked event → await reply via POST /permission/{id}/reply (oc-remote contract: reply = once|always|reject). Bounded wait (300s) → deny (fail-closed, never hang a session).

prompt

Sync prompt runner: POST /session/{id}/message semantics (captured live, testdata/m2/session_fixture.json + prompt_response.json + tool_fixture).

question

Question rendezvous — port of upstream Question service (opencode/src/question/index.ts): pending map, question.asked/replied/ rejected events, reply/reject resolution. Bounded: wait cap replaces upstream’s infinite Deferred await (AGENTS §2.3 — divergence documented in the runner: timeout resolves as a reject).

revert

Session revert / unrevert engine (SNAPSHOT.md §2, upstream session/revert.ts + session/summary.ts @ v1.18.31).

sift_boundary

Sift at the provider boundary (DIFFERENTIATION.md §4 / P1c).

snapshot

Snapshot engine (SNAPSHOT.md §2) — a faithful port of upstream’s shadow-git mechanism (packages/opencode/src/snapshot/index.ts @ v1.18.31).

spec

The frozen OpenAPI contract, embedded at compile time.

system_prompt

Model-facing system-prompt composition (v1 parity, K-CAPDIFF).

wire

Typed wire requests for the prompt family — the field-contract layer.

zen

Zen free-tier request shaping (bench/zen-probe/FINDINGS: P5/P6/P7/P8).
