- Clarify RtcSession/Channel ownership: ChannelId IS the session id;
RtcSession owns both str0m Live + codecs and the Channel. Fixes ambiguity.
- Drop the separate /ice endpoint: non-trickle ICE bundles candidates
into the SDP offer/answer, so the endpoint was redundant. Fixes
contradiction.
- Clarify idle timeout = 'no RTP for 60s' (not 5 min blanket), and that
no per-session tokio task is spawned (pre-paves the wrong pattern
for step 4's dedicated thread).
- 'reflex to police' -> 'reflex to enforce' (terminology: avoid
authoritarian verbs).
Workspace scaffold + spearhead step 1: browser talks WebRTC to the core,
core terminates DTLS-SRTP, decodes Opus to canonical 16-bit PCM @24 kHz mono,
echoes back. Proves the media core + the codec-to-PCM boundary (pre-paves
the tap). Stubs lock the ADR-0002 fused-vertical boundaries for steps
2/5/6.
Drafted in brainstorming session 2026-06-28.
Records the decisions from pressure-testing the four founding docs:
- North-star reframe: the engine for the AI-era contact center, not an
Asterisk-protocol successor (Asterisk's map = checklist, not template)
- Fused per-call vertical + composable horizontal platform (tightens the
three-plane model; removes the control<->media hot-path gRPC hop)
- Rust-native trunk SIP, IP-allowlisted; drops the Kamailio/rtpengine C
shield (reverses ADR-0001, to be formalized as ADR-0003)
- Pillars re-weighted: +data-ownership, spend-control promoted to
constitutive, WASM demoted out of the core story
- Developer-first DX spine (config-as-code, AEL lesson, engine+batteries)
- GUI as pure API client (FreePBX model) + k8s declarative/operational split
- Sequenced thin-slice first proof + capability ladder
For review before applying to README/ARCHITECTURE/PORT_PLAN and writing
ADR-0002 (identity) and ADR-0003 (SIP).

Record the SIP edge decision and align the docs:
- docs/adr/0001-sip-strategy.md: layered strategy (own Rust parser, rent the
interop tail via a Kamailio + rtpengine SBC, grow native core behind the shield);
pjproject FFI explicitly rejected for breaking the memory-safety thesis at the
most exposed seam.
- PORT_PLAN §1 + open decisions: SIP row updated to the decided strategy.
- ARCHITECTURE: "biggest technical risk" now points at ADR-0001.

Establish rutster — a memory-safe, API-first, security-first telephony
platform; spiritual successor to Asterisk for the WebRTC/microservices era.
- README: project framing, design pillars, open decisions
- docs/ARCHITECTURE.md: three-plane (control/media/app) model
- docs/PORT_PLAN.md: every Asterisk subsystem mapped to a disposition
(core / WASM-plugin / service / edge-FFI / dropped / replaced) with rationale
