OBJECTIVE: Provide editor-native insertion paths for frequent coding punctuation and paired symbols.

AUTHORITY: Parent #2 NS2: Mobile keyboard and command grammar; PRODUCT.md; REQUIREMENTS.md (PRODUCT.md; req: input/001-005; req: governance/001).

AGENT AUTHORITY:

  • Delivery authority: local-commit
  • Tracker authority: this issue may be commented and closed when acceptance passes.
  • Handoff state: committed clean, tracker commented/closed.

PARENT: #2 via explicit issue link and parent checklist.

SCOPE: The smallest source/docs/tests needed to make this behavior real and verified.

BOUNDARIES: No arbitrary snippets engine.

ACCEPTANCE: Trace tests insert braces, brackets, parens, slash, pipe, quotes, backtick, underscore, and chosen pairs with correct cursor placement.

VERIFICATION: Run the cheapest command that proves acceptance. Include regular tests for the intended payoff and adversarial tests for realistic failure, boundary, or regression cases. If no implementation test command exists yet, create/record the canonical command in AGENTS.md as part of the slice.

BLOCKERS: none

GOAL: Implement this vertical slice to the ACCEPTANCE above, keep the repo clean, cite relevant req: anchors in code/tests where applicable, and close only after verification passes.

Implemented in commit f793ecd726 (Add coding symbol rail).

Verification:

  • zig fmt src/main.zig src/session.zig src/protocol.zig src/leader.zig src/symbol.zig src/tui.zig: pass
  • zig build test: pass
  • zig build: pass
  • zig build run -- --help: pass
  • redgate lint / health: pass

Regular tests: symbol rail maps mobile-friendly letters to common coding punctuation; protocol commands insert slash/pipe/underscore and paired delimiters; pair insertion places the cursor between delimiters; TUI traces open the symbol rail and insert braces, brackets, parens, quotes, slash, pipe, and underscore.
Adversarial tests: unknown symbol keys do not dispatch or mutate the buffer; unknown protocol pair names are rejected; invalid UTF-8 pair insertion preserves existing bytes; symbol rail cancellation does not dispatch.

Boundary: source-patched symbol table plus leader/TUI/protocol insertion path only. No snippets engine, repeat-last-symbol behavior, runtime config, or broad command catalog added.
