 - Prefer links or pointers to canonical sources over copied lists.
 - Avoid project trees, architecture maps, generated inventories, current file sizes, issue lists, TODO inventories, and other snapshots that will rot.
 - Stable commands: `cargo run -p hemx-xtask -- test`, `cargo run -p hemx-xtask -- html-examples-smoke`, `cargo check --workspace`, `redgate health --strict`. Use the xtask runner for full verification so jobs are capped from local CPU and memory; use the html_examples smoke for focused repo-owned browser verification of the HTML pattern gallery, no-reload dynamic interactions, and no `/tmp` scripts. Keep fast crate tests, focused browser smoke, and full xtask authority distinct; the full path should stay within a documented 10 minute local timeout or be split into deterministic shards under the same wrapper. req: test/004 req: test/006 req: test/012 req: test/013 req: test/014 req: test/015 req: test/016

 - Run the workout product exemplar with `cargo run -p hemx-xtask -- workout dev` and open `http://127.0.0.1:3028`; set `HEMX_WORKOUT_ADDR=127.0.0.1:3030` if the default port is busy. Its durable visual direction and recovery expectations live in `examples/workout/DESIGN.md`. req: examples/008
 - Use the same Workout command surface for tests, production build, and mobile release: `cargo run -p hemx-xtask -- workout test`, `cargo run -p hemx-xtask -- workout build`, `HEMX_WORKOUT_ORIGIN=https://workout.example.com cargo run -p hemx-xtask -- workout mobile-release`, and `HEMX_WORKOUT_ORIGIN=https://workout.example.com cargo run -p hemx-xtask -- workout mobile-verify`; Android/iOS SDKs, store submission targets, and signing remain external blockers, not repo-owned secrets, and do not imply a broad `hemx-mobile` framework. req: examples/006 req: examples/011 req: examples/013
 - hemx core stays small: effects, typed ids, registries, and wire schema only; keep features in core only when they fit typed resources plus the closed EffectBatch op set, and treat DOM details as runtime lowering. Workspace crates stay separated, stable-Rust-compatible, and free of kitchen-sink boundaries; new primitives must delete special cases. Public identifiers should flow through typed wrappers over internal `ResourceId`/`ResourceRef`, not special-case opcodes. Wire output lowers symbolic authoring names to compact metadata and postcard/form-encoded envelopes, not JSON. ABI/schema versions and build fingerprints must guard runtime/server compatibility. v0 scope is the checked hypermedia core plus page/runtime/wire/diagnostic/test/axum proof, not optional sync/wasm/query/auth/router breadth. req: v0_scope/001 req: v0_scope/002 req: v0_scope/005 req: laws/001 req: invariant/001 req: invariant/005 req: typed_id/001 req: typed_id/003 req: effect_algebra/001 req: effect_algebra/006 req: wire/001 req: wire/002 req: wire/003 req: wire/004 req: wire/005 req: wire/006 req: abi/001 req: abi/002 req: abi/003 req: abi/004 req: abi/005 req: misc/001 req: misc/002 req: misc/003 req: misc/004 req: misc/005 req: misc/006 req: misc/007 req: misc/008 req: misc/009 req: misc/010
