5-76: LGTM: Comprehensive Rhai pivot with minor formatting issues.The document consistently replaces Lua with Rhai across all layers (runtime stack, gameplay authoring, bindings, tooling). The technical division remains sound.
Minor formatting issue: markdownlint flags missing blank lines around headings at lines 22, 32, 38, and 43. While not critical, fixing these improves markdown standards compliance.
Apply this diff to fix heading spacing:
- `rmg-cli` – CLI utilities --- + ## Rhai (gameplay authoring layer) ### Responsibilities(Repeat pattern for other flagged headings at lines 32, 38, 43)

455-557: Refactor authorization logic for clarity.The RmgStream handler consolidates ownership checks, epoch validation, and broadcast logic in a deeply nested structure spanning 100+ lines. While functionally correct, the cognitive complexity is high.
Consider extracting validation into dedicated functions:
validate_producer_authority(stream, conn_id, rmg_id) -> Result<(), ErrorPayload>validate_frame_sequence(stream, frame) -> Result<(), ErrorPayload>This would:
- Reduce nesting (currently 4-5 levels)
- Make error paths testable in isolation
- Improve readability of the happy path
- Allow reuse if other message types need similar validation
Example extraction:
fn validate_producer_authority( stream: &StreamState, conn_id: u64, rmg_id: RmgId, ) -> Result<(), ErrorPayload> { if let Some(p) = stream.producer { if p != conn_id { return Err(ErrorPayload { code: 403, name: "E_FORBIDDEN_PUBLISH".into(), details: None, message: format!("rmg_id {} is owned by {}", rmg_id, p), }); } } Ok(()) } fn validate_frame_sequence( stream: &mut StreamState, frame: &RmgFrame, ) -> Result<(), ErrorPayload> { match frame { RmgFrame::Snapshot(s) => { stream.last_epoch = Some(s.epoch); stream.last_hash = s.state_hash; stream.latest_snapshot = Some(s.clone()); Ok(()) } RmgFrame::Diff(d) => { let last = stream.last_epoch.ok_or_else(|| ErrorPayload { code: 409, name: "E_RMG_SNAPSHOT_REQUIRED".into(), details: None, message: "send a snapshot before the first diff".into(), })?; if d.from_epoch != last || d.to_epoch != d.from_epoch + 1 { return Err(ErrorPayload { code: 409, name: "E_RMG_EPOCH_GAP".into(), details: None, message: format!( "expected {}->{} but got {}->{}", last, last + 1, d.from_epoch, d.to_epoch ), }); } stream.last_epoch = Some(d.to_epoch); stream.last_hash = d.state_hash; Ok(()) } } }Then the main handler simplifies to:
Message::RmgStream { rmg_id, frame } => { let (subs, pkt) = { let mut h = hub.lock().await; let stream = h.streams.entry(rmg_id).or_default(); // Validate producer if let Err(payload) = validate_producer_authority(stream, conn_id, rmg_id) { let tx = h.conns.get(&conn_id).map(|c| c.tx.clone()); let ts = h.alloc_ts(); if let Some(tx) = tx { let pkt = encode_message(Message::Error(payload.clone()), ts)?; let _ = tx.send(pkt).await; } anyhow::bail!("producer authorization failed"); } // Validate and update sequence if let Err(payload) = validate_frame_sequence(stream, &frame) { let tx = h.conns.get(&conn_id).map(|c| c.tx.clone()); let ts = h.alloc_ts(); if let Some(tx) = tx { let pkt = encode_message(Message::Error(payload.clone()), ts)?; let _ = tx.send(pkt).await; } anyhow::bail!("frame sequence validation failed"); } // Set producer if first publish if stream.producer.is_none() { stream.producer = Some(conn_id); } let subs = stream.subscribers.clone(); let ts = h.alloc_ts(); let pkt = encode_message(Message::RmgStream { rmg_id, frame }, ts)?; (subs, pkt) }; let h = hub.lock().await; for sub in subs { if let Some(conn) = h.conns.get(&sub) { let _ = conn.tx.send(pkt.clone()).await; } } }

#![deny(missing_docs)]enforces comprehensive rustdoc on all public items
20-47: All public structs carry field-level rustdoc as required.
RmgEngine,rmg_node_id,rmg_tx_id,rmg_snapshoteach document intent and invariants. Repr(C) layout is correct for FFI.
49-74: Engine lifecycle functions properly documented with Safety sections.
rmg_engine_newandrmg_engine_freeestablish clear ownership semantics. Null-pointer handling correct (line 68–70 early return on null).
76-119:rmg_engine_spawn_motion_entity: FFI correctness with proper bounds checking.
- Null checks on all three pointers (line 93)
- UTF-8 validation (lines 97–101)
- Output written safely via unsafe dereference (line 116)
- All invariants documented in Safety block
121-189: Transaction and rewrite application functions: proper error handling.
rmg_engine_begin(lines 126–133): Null check + TxId wrapping ✓rmg_engine_apply_motion(lines 140–164): Validates tx.value ≠ 0, applies ApplyResult matching ✓rmg_engine_commit(lines 171–189): Writes snapshot hash via unsafe deref with validation ✓
191-228:rmg_engine_read_motion: Multi-step validation before unsafe access.Checks engine, output pointers, node ID, record existence, payload validity (lines 202–224). Deterministic output order (position, velocity) maintained.
230-245: Helper functions with safety comments; slice construction guarded.
handle_to_node_id(lines 230–237): Null-safe, returns Option.
copy_vec3(lines 239–245): Safety comment documents caller precondition (buffer ≥ 3 elements).
247-325: Test suite: determinism + error-path coverage.
ffi_motion_rewrite_is_deterministic(lines 273–312): Spawns two identical engines, applies motion rule, verifies snapshot hash equality and correct position/velocity reads ✓ffi_apply_no_match_returns_false(lines 316–324): Validates error path with bogus node ID ✓Tests are appropriate for bootstrap phase. Could expand with UTF-8 rejection test (line 98–100) or stale tx ID handling, but current scope is adequate.
Cargo.toml (2)
26-37: Release and bench profiles appropriately configured.
- Release (lines 26–30): LTO enabled, single codegen unit, stripped binaries (optimized for size + link-time optimization)
- Bench (lines 32–37): Derives from release, sets opt-level=3, disables LTO (faster compile), enables debug info (for profiling)
Profiles are sensible for the project scope.
3-20: Workspace members list correctly formatted with proper Cargo.toml manifests.Both new crates are properly defined:
crates/echo-session-ws-gateway: WebSocket-to-Unix-socket bridge (edition 2021, Apache-2.0)specs/spec-000-rewrite: Living spec for Echo/JITOS (edition 2024, Apache-2.0)No Rust source files exist yet in either crate, so SPDX header verification is not applicable at this stage. When .rs files are added, they must include the exact SPDX and copyright headers per coding guideline.
docs/rmg-demo-roadmap.md (2)
37-44: Demo 4 terminology updated from Lua → Rhai; determinism invariant preserved.
- Title (line 37): "Lua Live Coding Loop" → "Rhai Live Coding Loop" ✓
- Goal (lines 39–42): References updated; hot-reload and deterministic equivalence claims remain valid under Rhai ✓
- Determinism via replay (line 43) is architecture-independent; correct for Rhai ✓
71-71: Roadmap table entry aligned with Demo 4 section heading.Line 71: "Demo 4 Lua API" → "Demo 4 Rhai API" matches updated terminology in demo section.
crates/rmg-ffi/README.md (1)
7-7: FFI bindings README correctly advertises Rhai as first-class embedding target.Line 7 now positions C/C++ and Rhai host modules as equal consumers of the C ABI. Change aligns with module-level doc update in src/lib.rs (line 6).
docs/roadmap-mwmr-mini-epic.md (1)
54-54: Phase 3 rule registration example updated to Rhai syntax.Line 54 correctly shows Rhai map syntax:
register_rule{name, match, exec, ?id, ?revision}. Optional fields denoted; engine-computed behavior documented. Consistent with spec-mwmr-concurrency.md.docs/spec-rmg-core.md (2)
97-100: Rhai API surface example: syntax and semantics correct.Lines 98–100 correctly translate Lua table syntax
{entity = id}to Rhai map syntax#{ entity: id }. Function signature and semantic intent unchanged. Consistent with Rhai language specification.
88-106: API surface section covers all three language bindings consistently.
- Rust (lines 89–95): Low-level, direct engine calls ✓
- Rhai (lines 97–100): Scripting-layer binding with map parameters ✓
- TypeScript/WASM (lines 102–105): Async JS bindings ✓
All three preserve determinism semantics and naming conventions. Cross-language consistency maintained.
CONTRIBUTING.md (2)
44-49: LGTM: Clear WASM workflow documentation.The new living specs section provides precise, executable instructions. The bare URL on line 48 is appropriate for a localhost dev server reference—markdownlint's complaint is a false positive in this instructional context.
67-67: Good: Determinism constraint migrated to Rhai.The code style guidance correctly preserves Echo's determinism requirements for the new scripting layer.
crates/rmg-ffi/Cargo.toml (1)
8-8: LGTM: Package description accurately reflects Rhai integration.The updated description correctly distinguishes in-process Rhai hosting from C ABI for external consumers.
docs/phase1-plan.md (1)
14-116: LGTM: Consistent Rhai pivot throughout Phase 1 plan.All Lua references systematically replaced with Rhai across task descriptions, demonstrations, and completion criteria. The terminology is internally consistent and aligns with the broader repository pivot.
docs/spec-networking.md (1)
50-58: LGTM: Rhai syntax is accurate.The converted code examples use correct Rhai syntax:
fnkeyword for function definitions#{ key: value }for object literals::for namespace/module accessthiskeyword for method contextThe API surface documentation accurately reflects Rhai semantics.
README.md (2)
162-162: LGTM - Rhai pivot reflected correctly.The updated comment accurately reflects the scripting runtime pivot from Lua to Rhai, consistent with the decision-log entries and broader PR changes.
310-317: Developer benchmark documentation is clear.The benchmark documentation provides clear commands and references additional README documentation. Well-structured for developer onboarding.
WASM-TASKS.md (1)
6-6: Excellent test-first policy.The explicit "write failing tests first, then implement" policy aligns with best practices and the learnings indicating mandatory tests for runtime changes.
docs/spec-rmg-view-protocol.md (1)
1-73: Outstanding protocol specification.This RMG View Protocol spec is exceptionally well-structured:
- Clear authority model (single producer per RmgId)
- Comprehensive error taxonomy
- Gapless sequencing with hash validation
- Backpressure mechanism via ResyncRequest
- Reusable EIP template pattern
- Open questions section acknowledging unresolved design space
The 8 MiB MAX_PAYLOAD cap provides clear DoS protection. Error codes are specific enough for client debugging.
docs/spec-concurrency-and-authoring.md (1)

Based on coding guidelines.
182-247: Excellent authorization test coverage.The
non_owner_publish_is_rejected_with_errortest properly validates:
- Owner establishes authority via first snapshot
- Non-owner diff is rejected with E_FORBIDDEN_PUBLISH
- Error payload reaches the attacker
- Subscriber does not receive the invalid diff
- HTTP 403 code used appropriately
This test pattern should be replicated for other error codes (E_RMG_SNAPSHOT_REQUIRED, E_RMG_EPOCH_GAP).

- Scripting runtime pivot with clear justification
- RMG authority enforcement with error taxonomy
- CI security audit policy
Each entry follows the Context→Decision→Rationale→Consequence pattern perfectly. This documentation discipline makes the codebase exceptionally maintainable.

Scope classification must distinguish session-level errors from decode failures using error codes.
The current implementation blindly assigns NotifyScope::Local to all protocol errors, ignoring the semantic distinction provided by error codes:
- 3: Decode/wire failures →
Local(correct) - 403 (E_FORBIDDEN_PUBLISH): Session permission denied →
Global(incorrect; currently Local) - 409 (E_RMG_EPOCH_GAP, E_RMG_SNAPSHOT_REQUIRED): Protocol state violations →
Global(incorrect; currently Local)
The ErrorPayload structure provides both code and name fields—semantic markers already in use by the session service to distinguish error origins. The client must respect this distinction when routing notifications.
Implement error classification logic using the error code range or name prefix (e.g., code >= 400 or name.starts_with("E_FORBIDDEN")) to assign the appropriate scope.

axum 0.6 security advisories CVE
💡 Result:
Yes — axum had a known CVE: CVE-2022-3212 (RustSec RUSTSEC-2022-0055). It’s a denial‑of‑service / OOM issue where certain extractors didn’t set a default request-body size limit. Affected versions: axum <= 0.5.15 and 0.6.0-rc.1 (axum-core also affected). Fixes: axum >= 0.5.16 or >= 0.6.0-rc.2 (axum-core patched in 0.2.8 / 0.3.0-rc.2). Patched behavior sets a 2 MB default body limit — upgrade or apply an explicit body limit as a workaround. [1][2]

🌐 Web query:
axum-server 0.5 compatibility axum 0.7
💡 Result:
Short answer: No — use axum-server 0.7.x with axum 0.7.
Why: axum 0.7 introduced hyper 1.0 and other breaking API changes; axum-server published 0.7.x to match (the axum-server crate shows 0.7.x releases and examples using axum 0.7). axum-server 0.5 (older release) predates those changes and is not guaranteed to work with axum 0.7. [1][2]
Sources:
- axum 0.7 announcement (hyper 1.0 / API changes). [1]
- axum-server crate / releases and examples showing axum 0.7 support (use axum-server 0.7.x). [2]
Upgrade both axum and axum-server to compatible versions; axum 0.6 + axum-server 0.5 are severely outdated.
The manifest specifies axum = "0.6" and axum-server = "0.5", both of which are multiple major versions behind current stable (axum 0.8.4, released Apr 2025). Beyond staleness:
-
Security: CVE-2022-3212 (RUSTSEC-2022-0055) is a denial-of-service/OOM vulnerability in axum extractors that affected 0.6.0-rc.1. While patched in later 0.6.x releases, using 0.6 at all leaves you vulnerable to this class of issue.
-
Incompatibility: axum-server 0.5 is incompatible with axum 0.7+ due to breaking changes introduced by hyper 1.0 integration in axum 0.7. Upgrading axum alone while keeping axum-server 0.5 will cause compilation or runtime failures.
Action: Upgrade both together. Use axum-server 0.7.x paired with axum 0.7.x, or axum-server 0.7.x with axum 0.8.x for the latest stability and security posture.

Unbounded accumulator — DoS vector if upstream sends malformed data.
The acc vector grows without limit. If the upstream Unix socket sends data that never completes a valid frame (malicious or buggy), memory consumption is unbounded. An attacker controlling the upstream could exhaust memory.

🧹 Nitpick | 🔵 Trivial
Orphaned #app div — Leptos mounts to <body>, not this element.
The <div id="app"></div> sits here doing absolutely nothing. In lib.rs:44, you call leptos::mount_to_body(...), which renders the component directly into <body>, completely bypassing this div.
Either:
- Remove the orphaned div (it's dead weight), or
- Use
leptos::mount_to(document().get_element_by_id("app").unwrap(), ...)if you want controlled mounting.
If mounting to body is intentional (common pattern), clean up the HTML:

In WASM-TASKS.md around lines 8 to 41 the section headings (## P0 — Bootstrap &
Scaffold, ## P1 — Kernel Bindings & Types, ## P1 — UI MVP (Living Spec), ## P2 —
Certification & Win Condition, ## P2 — Tooling & CI, ## P3 — UX & Resilience, ##

74-78: IN PROGRESS entry lacks actionable next steps and artifact link.Line 78 states "checklist drafted" but does not specify:
- Where the checklist lives (mentioned as "docs/tasks.md" but not hyperlinked or cited with line range).
- What the next step is (refine checklist? identify owners? open sub-issues?).
Update to: "
Status: checklist drafted in docs/tasks.md; next: refine slice owners and set dep order."
481-497: Code Tasks subsection appears TypeScript-focused despite Rust-first PR objective.Lines 481–497 ("Code Tasks (Phase 1 prep)") reference Vitest,
packages/echo-core/test/, and TypeScript-centric tasks. Per the PR description, Echo is pivoting to Rust + WASM + TS. This section should either:
- Clarify that these are legacy TypeScript prototype tasks (to be archived), or
- Add a parallel Rust-focused subsection (e.g., "Rust Code Tasks (Phase 1 prep)") covering rmg-core, FFI, WASM harness, and deterministic tests.
For a living document, this ambiguity could mislead future Codex into deprioritizing Rust work.
509-519: Decision Log is sparse and strategically incomplete.The Decision Log contains only 3 entries over a 2-month project (2025-10-23 to 2025-10-25). Per the document's own guidance (line 16), "major decisions" should be recorded in
docs/decision-log.mdand a concise summary copied here. The table is missing:
- WASM gating and spec-000 scaffold decision (implied by PR, but not in log).
- WS gateway architecture choice (UDS+WS bridge vs. alternatives?).
- Rhai vs. Lua scripting decision (only the pivot is mentioned; no rationale or alternatives considered).
- RMG View Protocol adoption (if major architectural choice).
Either expand this table to capture recent decisions with rationale, or clarify that it is strategic-only (not operational) and reference full entries in
docs/decision-log.md.
544-550: Out-of-order historical notes break chronological readability.Lines 544–550 contain historical notes (dated 2025-11-02) appended after the main document structure. This breaks the mental model: a reader expects either:
- A separate "Recent History" or "Archive" section, or
- All historical entries (2025-11-02 and later) integrated into the main "Today's Intent" and "Decision Log" tables in chronological order.
Currently, a reader scanning the document sees 2025-12-13 at line 38, then jumps backward to 2025-11-02 at line 544, causing confusion.
Proposed fix: Move lines 544–550 into a new "Archive / Recent History" section before "Notes to Future Codex," or integrate them into the main Today's Intent table in reverse chronological order.
25-33: Phase Overview table is clear but lacks estimated timelines.The Phase table (lines 27–32) maps Phases 0–3 with goals and status, but omits:
- Estimated duration (e.g., "Q4 2025", "4 weeks")
- Assigned owners or teams
- Blocking dependencies between phases
For a living document, adding a "Est. Duration" column and optional "Owner" field would prevent timeline drift and clarify resource constraints.
463-479: Backlog is thorough but needs triage severity markers.The Immediate Backlog (lines 463–479) contains ~25 items mixing:
- Core infrastructure (ECS storage, scheduler, branch tree, math module).
- Phase 1 preparation (Rust workspace, FFI, WASM, CLI).
- Future exploration (browser adapters, physics, audio, network).
Without a Priority or P-level column, future Codex cannot quickly identify which items block others or have hard dependencies. Consider adding:
| Item | P-Level | Blocked By | Blocks | |------|---------|-----------|--------| | Scaffold Rust workspace | P0 | — | Port ECS, FFI | | Port ECS archetype storage | P0 | Rust workspace | Implement deterministic PRNG | | …
535-542: "Notes to Future Codex" section is well-intentioned but vague.Lines 535–542 document principles (update docs, test gaps, determinism, GC pins, diagrams, breadcrumbs) but lack:
- Enforcement: How are these checked? (CI gate? weekly audit?)
- Specificity: "Record test coverage gaps as they appear"—where? (test file comments? decision log? GitHub Issues?)
- Measurability: "Keep Echo's spine alive" is motivational but not actionable.
Suggested addition: Link principles to specific files/tools. Example:
- "Record test coverage gaps in
crates/rmg-core/tests/TODO-COVERAGE.md; link from PR summaries."- "Pin GC decisions in code comments (
// GC INVARIANT: …) and cross-reference in decision log."Cargo.toml (1)
3-3: Norust-versionspecified — you're setting contributors up for failure.Multiple child crates use
edition = "2024"which requires Rust 1.85+. The workspace root should declare:[workspace.package] rust-version = "1.85"Without this, Cargo won't warn users on older toolchains until they hit cryptic edition errors. This is basic hygiene for a project using bleeding-edge editions.

11-11: Trailing whitespace on line 11 — still not fixed.This was flagged in a previous review. The trailing space remains. Remove it.
77-81: Markdown formatting issues persist — heading spacing and bare URL.Previously flagged: Line 77 needs a blank line after the heading, and line 79's bare URL should use proper link syntax. These are still present.

8-41: Heading spacing issues — already flagged, still not fixed.Every
## P<N>heading lacks the required blank line before the first list item. This was called out in a previous review with specific line numbers (8, 13, 18, 24, 29, 34, 40). Either fix them or configure your linter to shut up about it — the current state is sloppy.crates/echo-session-ws-gateway/src/main.rs (4)
132-145: No timeout on Unix socket connect — still not addressed.Previously flagged:
UnixStream::connectcan hang indefinitely if the socket exists but the service is unresponsive. A client will wait forever with no feedback. Wrap withtokio::time::timeout.
160-179: Unbounded accumulator remains a DoS vector.Previously flagged: The
accvector at line 165 grows without limit. If upstream sends malformed data that never forms a complete frame, memory consumption is unbounded. Add a cap (e.g., 16 MiB) and return an error when exceeded.
214-224: Ping loop still fires immediately on first tick.Previously flagged:
tokio::time::intervalyields immediately on first.tick().await. The client receives a ping within milliseconds before any real traffic. Skip the initial tick:interval.tick().await; // discard immediate first tick
298-333: Frame length calculation duplicated — DRY violation persists.Previously flagged:
validate_frame(lines 306-309) andtry_extract_frame(lines 324-327) both compute12 + len + 32with identical checked arithmetic. Extract a helper:fn compute_frame_len(payload_len: usize) -> Result<usize> { 12usize .checked_add(payload_len) .and_then(|v| v.checked_add(32)) .ok_or_else(|| anyhow!("frame length overflow")) }Then use it in both functions. This is copy-paste engineering at its finest.

docs/decision-log.md (1)
9-12: ✓ Decision entries are well-structured and clear.Lines 9–12 establish clear architectural decisions (WS gateway, Rhai scripting pivot, RMG authority enforcement) with solid rationale and consequences. Entries are appropriately scoped and reference specific crates/error codes. Format is consistent with the log's table structure.
docs/execution-plan.md (2)
1-22: Excellent operational discipline in document structure and update rhythm.The Operating Rhythm section is clear, actionable, and enforces accountability:
- Pre-work sync (lines 11–14): ensures clean state and alignment.
- During-work logging (lines 15–17): enables async handoff.
- Post-work summary (lines 18–21): future-proofs state.
This is the gold standard for living project documents. Maintain this rigor.
36-36: "Today's Intent" section is well-named and operationally sound.Each entry follows a consistent pattern: date, title, goal, scope, status. This makes it easy for future Codex to scan and prioritize. ✓
specs/spec-000-rewrite/Trunk.toml (1)
1-10: LGTM — Trunk configuration is minimal and correct.The
filehash = truefor cache-busting and explicitwasmfeature activation are appropriate for a living spec scaffold. Nothing to nitpick here, which frankly disappoints me.specs/spec-000-rewrite/Cargo.toml (1)
6-6: Edition 2024 again — you're playing with fire across multiple crates.Same issue as
echo-wasm-abi. Either this is a deliberate project-wide decision (in which case, document it in the workspace root and stop making me repeat myself), or you copy-pasted without thinking. Neither is acceptable without explicit MSRV documentation.README.md (1)
312-318: Benchmark section looks correct and actionable.Clear commands with expected outputs. The
http://localhost:8000URL should arguably be wrapped in angle brackets per markdown conventions, but I'll let it slide since it's in a code block context.WASM-TASKS.md (1)
6-6: Policy statement is excellent — lead with tests, document completions."Write failing tests first, then implement; check off tasks only when tests and docs are updated." This is the correct mindset. If only the markdown formatting matched the discipline.
Cargo.toml (1)
17-21: New workspace members are consistent with PR scope.Adding
echo-wasm-abi,echo-session-ws-gateway,specs/spec-000-rewrite, andecho-wasm-bindingsaligns with the WASM scaffold objectives. The ordering is slightly inconsistent (specs mixed with crates), but that's cosmetic.crates/echo-session-ws-gateway/src/main.rs (2)
1-5: Header and module doc are correct.SPDX header matches the required format exactly. Module documentation is concise and accurate. Nothing to complain about here, much to my dismay.
226-284: Task lifecycle management is now properly handled — previous issue resolved.The introduction of
EndReasonenum withtokio::select!and explicit abort/cleanup addresses the previous concern about backend disconnects leaving the ping loop running and task errors being swallowed. The cleanup sequence at lines 254-268 is correct: abort background tasks, drop the sender, then best-effort flush with timeout before force-cancel.Line 283's
let _ = ping.awaitafter abort is fine — it just consumes theJoinError::Cancelled.specs/spec-000-rewrite/src/spec_content.rs (1)
1-5: Header and implementation are flawless.The SPDX header is exactly compliant with coding guidelines. The copyright line matches character-for-character. The
include_str!macro correctly embedsspec.md(28 lines) at compile time—no path resolution issues, no missing dependencies.This is correct code.

🧹 Nitpick | 🔵 Trivial
Origin check is secure but consider logging rejected origins for debugging.
The logic is correct: if allow_origins is None, all origins pass; otherwise, the Origin header must match exactly. Returning false when the header is missing or malformed is the secure default.
However, consider logging the rejected origin value (if parseable) at debug! level for troubleshooting CORS issues in deployment.

In crates/echo-session-ws-gateway/src/main.rs around lines 286 to 296, the
origin check correctly enforces allowed origins but does not log rejected

Edition 2024 requires Rust 1.85+ — MSRV not documented anywhere.
This crate uses edition = "2024", which was stabilized February 20, 2025 in Rust 1.85.0. Without a documented rust-version field at the package or workspace level, contributors on older toolchains will hit catastrophic compilation failures with error messages that have nothing to do with the actual problem.
Add rust-version = "1.85" to the workspace root Cargo.toml under the [workspace] section, or add it locally to this package's [package] section if intentionally isolating the 2024 edition constraint.

errors — preferably add rust-version = "1.85" under the top-level [workspace] in
the workspace root Cargo.toml, or if you intend to isolate the requirement to
this crate, add rust-version = "1.85" under this package's [package] section in

🧹 Nitpick | 🔵 Trivial
Loose version specifiers — pin to minor versions for reproducibility.
You've declared "1", "3", and "1" which resolve to ^1.0.0, ^3.0.0, and ^1.0.0 respectively. While Cargo's SemVer resolver is generally sane, for a library crate that will be consumed by other workspace members, you're gambling on future minor releases not introducing subtle breaking changes in serialization behavior. At minimum, pin to 1.0 / 3.0 to signal intent.

serde_json deps use loose version specifiers ("1", "3", "1"); replace them with
pinned minor versions (e.g., "1.0" for serde and serde_json, "3.0" for
serde_with) while keeping existing features, then update the lockfile (run cargo

🛠️ Refactor suggestion | 🟠 Major
Public API rustdoc is superficial — missing invariants, usage guidance, and field semantics.
Every public type has a doc comment, but they're bare-minimum descriptions that fail to explain:
-
Invariants: Do node IDs have uniqueness constraints? Can edges reference non-existent nodes? What happens to edges when a node is deleted?
-
Field semantics: Which
SemanticOpvariants useold_valuevsnew_valueinRewrite? ForConnect/Disconnect, what do those fields contain — node IDs, edge metadata, or nothing? -
Usage patterns: No examples showing how to construct valid rewrites or compose these types.
-
Relationships: How does
Rmgrelate toRewrite? Is materialization order-dependent?
Based on learnings, public APIs must explain intent, invariants, and usage. Current docs satisfy only "intent" at a surface level.
🔎 Example enhanced rustdoc
/// Rewrite record (append-only).
///
/// Captures a single semantic operation against the graph along with
/// reversibility data (old/new values). Rewrites form an immutable log
/// that can be replayed to materialize graph state.
///
/// # Field semantics by operation:
/// - `Set`: `old_value` = prior field value (or None), `new_value` = new field value
/// - `AddNode`: both values None (node creation has no prior state)
/// - `DeleteNode`: values may capture tombstone metadata
/// - `Connect`/`Disconnect`: values currently unused (edge operations tracked via target)
///
/// # Example:
/// ```
/// use echo_wasm_abi::{Rewrite, SemanticOp, Value};
///
/// let rw = Rewrite {
/// id: 42,
/// op: SemanticOp::Set,
/// target: "node-1".into(),
/// old_value: Some(Value::Num(10)),
/// new_value: Some(Value::Num(20)),
/// };
/// ```
#[serde_as]
#[derive(Clone, Debug, PartialEq, Serialize, Deserialize)]
pub struct Rewrite {
// ... fields
}Apply similar expansions to Rmg, SemanticOp, and Node/Edge to document their contracts.
Based on learnings, this must be addressed before the API stabilizes.

In crates/echo-wasm-abi/src/lib.rs around lines 10–85, the public rustdocs are
too terse; expand them to state invariants, field semantics, and usage examples
for NodeId/FieldName, Value, Node, Edge, Rmg, SemanticOp, and Rewrite. Specify
invariants (e.g., node ids must be unique within an Rmg, whether edges may
reference missing nodes and what that implies, and edge behavior on node
deletion), document exactly which SemanticOp variants populate Rewrite.old_value
vs Rewrite.new_value (and what those Option<Value> values represent for
Set/AddNode/DeleteNode/Connect/Disconnect), clarify how Rmg is materialized from
a sequence of Rewrites and whether order matters, and add a short code example
for constructing common rewrites (Set, AddNode, Connect). Ensure each public
type/doc includes intended semantics and any guarantees callers can rely on.

💡 Result:
Yes — JsValue::from_serde (and into_serde) in wasm-bindgen is deprecated. Use either the serde-wasm-bindgen crate (recommended) or the extension in gloo-utils (gloo_utils::format::JsValueSerdeExt) instead. [1][2]

serde_wasm_bindgen to_value wasm-bindgen current recommendation
💡 Result:
Short answer: use serde-wasm-bindgen::to_value (or gloo_utils::JsValueSerdeExt) — avoid wasm-bindgen's built-in from_serde/into_serde (they were removed/deprecated because of dependency-cycle/serde_json issues). Use serde-wasm-bindgen::preserve when you need to keep native JS objects (Date, RegExp, etc.). [1][2][3]

💡 Result:
Short answer: Yes — use serde-wasm-bindgen (or gloo_utils for the JSON approach). The wasm-bindgen built-in serde helpers (from_serde / into_serde / serde-serialize feature) are deprecated; the guide and API docs direct you to serde-wasm-bindgen (and gloo_utils::format::JsValueSerdeExt) as the recommended paths. [1][2][3]
Sources:
- wasm-bindgen guide: "Serializing ... with Serde" — recommends serde-wasm-bindgen. [1]
- wasm-bindgen JsValue docs — points to serde-wasm-bindgen / gloo_utils and marks into_serde/from_serde deprecated. [2]
- wasm-bindgen API docs / features — serde-serialize feature deprecated; use serde-wasm-bindgen. [3]
Replace deprecated JsValue::from_serde() with serde_wasm_bindgen::to_value().
Lines 305 and 309 use the deprecated JsValue::from_serde() method. The wasm-bindgen team removed this due to dependency-cycle and serde_json issues. Replace with serde_wasm_bindgen::to_value() (or gloo_utils::format::JsValueSerdeExt as an alternative). This will break in future wasm-bindgen versions.

CRITICAL: Invalid Rust edition will prevent compilation.
Your Cargo.toml declares edition = "2024", which does not exist. Rust supports only 2015, 2018, and 2021. This will cause immediate build failure. Change to edition = "2021".
The Leptos 0.6 CSR configuration is correct, and your Trunk.toml properly gates the wasm-bindgen optional dependency via feature flags. However, none of this matters if the project won't compile.

In specs/spec-000-rewrite/Cargo.toml around lines 18 to 20, the Cargo.toml
specifies an invalid Rust edition ("2024"); update the edition field to a
supported value (change it to "2021") so the project can compile, then run cargo
check to verify the fix.

There was a problem hiding this comment.
🧹 Nitpick | 🔵 Trivial
Win condition section marked "to add" — needs implementation.
The specification explicitly marks this section as incomplete. The win condition is critical for defining success criteria for the interactive demo.
Do you want me to generate a more detailed win condition specification or open a tracking issue for this TODO?

In specs/spec-000-rewrite/spec.md around lines 22-23, the "Win Condition (to
add)" placeholder must be replaced with a concrete specification: define that a
win occurs when the current graph is isomorphic to a predefined target graph
under the allowed node/edge labeling and rewrite semantics (describe exact
matching rules and whether graph isomorphism allows relabeling), require that
the full sequence of applied rewrites be recorded and validated atomically,
specify that upon reaching the target the system emits a canonical completion
hash (define the hash input as canonical serialized graph + ordered rewrite
sequence + optional metadata and the algorithm, e.g., SHA-256), and state any
tie-breaker/partial-match behaviors (e.g., only exact matches count) plus
expected API/events and an example of input->hash mapping for testability.
