 | Date | Context | Decision | Rationale | Consequence |
 | ---- | ------- | -------- | --------- | ----------- |
-| 2025-12-10 | CI cargo-audit warnings | Keep `cargo audit --deny warnings` green by ignoring RUSTSEC-2024-0436 (paste unmaintained via wgpu/metal) and RUSTSEC-2021-0127 (serde_cbor legacy advisory) in `security-audit.yml`. | Paste is an unmaintained transitive dep of wgpu with no downstream replacement yet; serde_cbor was removed from the codebase but may reappear through cached lockfiles—ignoring prevents CI flakiness while we track upstream updates. | Security audit job passes; advisories remain documented and will surface again once upstreams ship replacements or if serde_cbor re-enters the tree. |
+| 2025-12-10 | CI cargo-audit warnings | Keep `cargo audit --deny warnings` green by ignoring RUSTSEC-2024-0436 (paste unmaintained via wgpu/metal) and RUSTSEC-2021-0127 (serde_cbor legacy advisory) in both `security-audit.yml` and `ci.yml`. | Paste is an unmaintained transitive dep of wgpu with no downstream replacement yet; serde_cbor was removed from the codebase but may reappear through cached lockfiles—ignoring prevents CI flakiness while we track upstream updates. | Security audit jobs now ignore these advisories in both workflows; advisories remain documented and will surface again once upstreams ship replacements or if serde_cbor re-enters the tree. |
 | 2025-12-10 | CI cargo-deny index warnings | Prime crates.io index with `cargo fetch --locked` in the `deny` job before running `cargo-deny` (ci.yml). | `cargo deny` was emitting `warning[index-failure]` when it tried to query yanked status without a local index; warming the index prevents network flakiness from spamming logs and fails early if fetch cannot reach crates.io. | CI is quieter and deterministically fails on real connectivity issues; yank checks now use the warmed cache instead of best-effort network lookups during the deny step. |
+| 2025-12-10 | RMG View Protocol plan | Added `docs/tasks.md` with a checklist to deliver the RMG View Protocol (pub/sub authority, dirty-loop publishing, demo path, tests) and logged intent in execution-plan. | Centralizes the work needed to demo multi-viewer shared RMGs and sets commit-by-slice expectations. | Provides a single progress list; future slices will check off items and keep docs aligned. |
 | 2025-12-10 | CBOR migration + viewer gating | Replaced archived `serde_cbor` with `ciborium` in proto/graph (canonical encoder/decoder with serde_value bridge), marked graph enums `#[non_exhaustive]`, made canonical hashing return `Result`, and aligned egui deps/input handling (pointer & WASDQE gated to View, escape only on keydown, snapshot hash mismatch desyncs). | Keeps wire format on a maintained crate, avoids namespace pollution, and prevents silent desyncs or UI mutation outside the View screen; removes raw pointer aliasing in app_events. | Canonical framing stays deterministic on supported MSRV, oversized ints surface errors, viewer input is safer/debuggable, and CI dependency alignment avoids egui patch skew. |
 | 2025-12-10 | Viewer timing + session buffering | Capture frame `dt` once per frame and reuse for camera/layout/arcball; compute angular velocity using `angle/dt` with epsilon and zero-angle guard; session client now buffers header/payload/checksum across reads, decodes only when a full packet is present, and never drops partial data. | Prior code reset `last_frame` before `elapsed()` uses, producing zero dt and runaway angular velocities; arcball used a bogus constant divisor; poll_message dropped partial headers and over-allocated payloads. | Viewer motion/decay uses correct per-frame delta and stable spin; angular velocity matches actual drag speed; session client keeps stream in sync and surfaces `Ok(None)` only when truly no data. |
 | 2025-12-10 | Config + docs alignment | README points to `ConfigStore` and correct doc path; proto reexports are explicit with serde-renamed `AckStatus::{Ok,Error}`; constellation figure labeled/cross-referenced with anchored legend. | Aligns docs with actual APIs and keeps figure references stable. | Less namespace pollution, accurate docs, and reliable LaTeX figure placement. |

+# RMG View Protocol Tasks
+
+- [ ] Define the “RMG View Protocol” package: channel naming, RmgId + owner identity, publisher-only writes, message pattern (snapshot + diff, gapless epochs, hashes/acks), transport (canonical CBOR, MAX_PAYLOAD, non-blocking).
+- [ ] Generalize as an Echo Interaction Pattern (EIP) template capturing roles, authority, message types, flow styles (req/resp, pub/sub, bidir), reliability/validation hooks for future services.
+- [ ] Enforce authority: session-service rejects non-owner writes on the RMG channel; client surfaces errors.
+- [ ] Dirty-flag sync loop in viewer: mark dirty on mutation, publish snapshot/diff on net tick when dirty, clear on ack; throttle/batch as needed.
+- [ ] Publish/subscribe toggles in UI: enable/disable sending my RMG and receiving per RmgId, preserving epoch/hash continuity when re-enabled.
+- [ ] Session-service wiring: add publish endpoint, validate owner + gapless epochs/hashes, rebroadcast to other subscribers; explicit error codes.
+- [ ] Client wiring: implement publish call + retry/backoff; handle authority/hash errors and resync requests.
+- [ ] Demo path: script/doc for one session-service + two viewers (one publisher, one subscriber) showing shared RMG changes.
+- [ ] Tests: protocol conformance (authority rejection, gapless enforcement, dirty-loop behavior, toggle respect) and integration test with two clients + server loopback.
+- [ ] Docs sync: update execution-plan intents and decision-log entries as slices land.
