description: >
  Extend agents/context/check-project-boundary.sh BLOCK message (the same one updated
  in T-1089 for write ops) to mention 'fw termlink dispatch --project /path --prompt
  cat README.md' as the read-only escape pattern. Currently agents must ask the human
  to authorize each cross-project read individually. Origin: G-027. Trigger: cross-session
  ring20-dashboard onboarding incident 2026-04-11 — agent needed to read sibling READMEs
  and had no documented escape.

# T-1096: Boundary hook: surface TermLink dispatch read-only escape route in BLOCK message (G-027)

## Context

<!-- One sentence for small tasks. Link to design docs for substantial ones. -->

## Acceptance Criteria

### Agent
- [x] Write/Edit block message in check-project-boundary.sh mentions
      TermLink dispatch as escape route for cross-project reads
- [x] Block message includes copy-pasteable example command
- [x] Existing tests still pass

## Verification

bash -c 'echo '"'"'{"tool_name":"Write","tool_input":{"file_path":"/opt/other/file.txt"}}'"'"' | PROJECT_ROOT=/opt/999-Agentic-Engineering-Framework bash agents/context/check-project-boundary.sh 2>&1 | grep -q "termlink"'
# The completion gate runs each command — if any exits non-zero, completion is blocked.
