- Defer provider runtime factory loading until workflow execution
- Keep macro resolution on the same lazy runtime path
- Avoid eager provider module startup in tool registry and parity flows

- Share a lightweight provider runtime mock across tool and parity tests
- Keep synthetic provider performance crawls on the inline path for deterministic timing
- Add narrow branch coverage for bootstrap fallback omission and selector fallback handling

- add canvas manager, document store, relay protocol, and CLI/tool surfaces
- wire extension canvas transport and remote manager support
- cover canvas runtime, relay, and help surfaces with focused tests

- remove dead provider fallback branches after reason normalization
- add targeted provider and launch regression coverage for the final gap
- keep the repo gate at 97 percent branch coverage without behavior drift

- update README, architecture, CLI, and troubleshooting references for canvas
- sync agent guidance and best-practices skill docs with the new relay channel
- refresh surface inventories and status semantics to match implementation

- add the real canvas editor surface and shared extension session coordination
- switch canvas documents and feedback flows to the typed live-sync runtime
- harden verification with canvas regressions and full green repo gates

- add a shared palette contract for canvas design surfaces
- switch the extension stage and export renderer to white defaults

Co-authored-by: Codex <noreply@openai.com>

- assert export surfaces emit the shared white-surface tokens
- assert the extension stage uses the same design-surface palette

- add canvas code-sync managers and TSX import/export helpers
- expand extension, relay, CLI, and tool flows for canvas and annotation parity
- keep preview, session routing, and target forwarding aligned across modes

Co-authored-by: Codex <noreply@openai.com>

- add regression coverage for code sync, runtime preview, and target forwarding
- lock relay, annotation, and extension flows against the new canvas surfaces
- keep CLI and inventory assertions aligned with the public command surface

Co-authored-by: Codex <noreply@openai.com>

- align README, AGENTS, and docs with the current CLI, tool, and canvas surfaces
- refresh opendevbrowser best-practices assets and validation guidance
- remove stale design and cutover plans that no longer reflect the repo baseline

- delete the obsolete canvas parity audit document from the design-canvas branch
- keep the untracked competitive implementation spec out of scope for this PR
