Tasks: Self-Printing Schema

Input: Design documents from /specs/002-self-printing-schema/

Prerequisites: plan.md, spec.md

Tests: Required by constitution IV and AGENTS.md (new method → integration test).

Format: [ID] [P?] [Story] Description

Phase 1: Canonical lists in proto (US1+US2 foundation)

• T001 [US1] Add failing test in crates/signaltty-proto/src/lib.rs: ALL slices contain every named constant, no duplicates (write ALL first as empty to watch it fail, or assert on a member before adding the slice)
• T002 [US1] Add method::ALL, event::ALL, code::ALL + method::SERVER_SCHEMA in crates/signaltty-proto/src/lib.rs; cargo test -p signaltty-proto

Phase 2: Server handler (US1)

• T003 [US1] Add h_server_schema + dispatch arm in crates/signaltty-server/src/router.rs built from the ALL slices; cargo test -p signaltty-server

Phase 3: Sync test (US2)

• T004 [US2] Add schema_lists_every_dispatched_method to crates/signaltty-server/tests/integration.rs: call server.schema, probe every method except server.shutdown with {}, assert no UNKNOWN_METHOD; assert key members present. cargo test -p signaltty-server --test integration schema_

Phase 4: CLI + docs (US1)

• T005 [P] [US1] Add Schema variant + match arm in crates/signaltty-cli/src/main.rs (status-command pattern); verify with a live signaltty schema / schema --json run
• T006 [P] [US1] Add server.schema row to the methods table in docs/08-ipc.md

Phase 5: Verification

• T007 Run cargo fmt --check, cargo clippy --workspace --all-targets, cargo test --workspace

Dependencies & Execution Order

• T001 → T002 → T003 → T004 → (T005, T006 in parallel) → T007

Notes

• server.shutdown is listed in the schema but excluded from the probe loop: with {} on an idle store it would stop the fixture server. Its dispatch is covered by existing shutdown tests.
• Probing workspace.create with {} creates one empty workspace in the ephemeral fixture — harmless, assertion is dispatch-only.
• Commit as server: self-printing schema (server.schema + CLI) after T007 (CLI + docs ride along; one concern: the contract).
