+A test double, not an agent. It ignores the prompt text, performs the
+`tick-checkbox` behavior from tests/harness/fake-executor on task 1.1, and prints
+its passdown.result/v1 payload as the last line of stdout. It reads the
+attempt ID from `PASSDOWN_ATTEMPT`, which the host must export (dispatch
+step 6). Launch it from the attempt location, in a new process group, with
+stdin closed.

+You are a delegated worker for attempt pd-20260926T173842Z-0c67dcab.
+
+## Task reference
+
+Plan: docs/plan.md
+Task ID: 1.1
+Exact ref: docs/plan.md#1.1
+
+## Task
+
+- [ ] 1.1 Add the greeting [dispatch: fake]
+  - Paths: src/
+  - Done criteria: src/hello.txt says hello
+  - Verification: `grep -q hello src/hello.txt`
+
+## Authority
+
+You are a delegated worker. Implement only task docs/plan.md#1.1. Do not edit the plan file: no checkbox changes, no `Dispatched:` lines, no edits to done criteria or verification. Report your outcome, changed paths and verification evidence; the host decides whether the task is complete.
+
+## Environment
+
+If a command fails because of sandbox, permission, or network restrictions, STOP and report the error verbatim. Do not work around it (no HOME redirects, no local caches, no config or project-file edits).
+
+## Depth
+
+Do not dispatch this work, or any part of it, to another external agent CLI. Your provider's own native subagents are your provider's business.
+
+## Result
+
+End with one JSON object matching `passdown.result/v1` for attempt pd-20260926T173842Z-0c67dcab as your final output. If the task is ambiguous, do not guess and do not write: return `needs_input` with your question. If a command is denied by sandbox, permission or network rules, stop and return `blocked` with the error verbatim.
+
+The schema for `passdown.result/v1` is:
+
+{
