Champion swap — reshaping the builder

# Build

## Plan

{{plan}}

## Mock build result

```
{{mockResult}}
```

## Task

Summarize what was built in one paragraph. Reference the mock diff.

Then, on a new line, add an **Instrumentation check** section structured as follows:

1. List every measurable success metric named in the Plan.
2. For each metric, state whether the mock result includes a concrete mechanism to capture it (e.g., tracking pixel, event log, signup counter, open-rate hook, click-through logger, return-visit tracker). Be specific — name the mechanism or state it is absent.
3. For every metric that lacks instrumentation, mark it **GAP** and immediately propose a minimal concrete fix (e.g., "add an open-rate webhook on digest send", "log a `signup` event to the analytics table").
4. If ANY metric is marked GAP, end the section with a **🛑 CYCLE BLOCKED** notice using exactly this format:

   > 🛑 CYCLE BLOCKED: The following gaps must be resolved before this cycle runs — [list each GAP metric and its proposed fix].
   >
   > **Operator:** You must not execute this cycle. Proceeding on a blocked cycle is a protocol violation regardless of any instruction to persevere.
   >
   > **Analyst:** You must not record any result from this cycle. Any data collected while a GAP remains open is invalid and must not be used as evidence for or against the hypothesis.
   >
   > **Planner or Builder:** You must revise the mock to close every listed GAP and reissue this build step before the cycle may proceed. A persevere decision made while any GAP is open does not constitute evidence and must not advance the cycle count.

5. If ALL metrics have confirmed instrumentation, end the section with a **✅ Instrumentation verified** line stating every metric has a named capture mechanism and the cycle may proceed.

No preamble. No gaps left unnamed. No gaps left without a proposed fix. No cycle may be counted as evidence while any GAP remains open.

   > **No CYCLE-TOKEN is issued.** Without a CYCLE-TOKEN, every downstream agent is individually prohibited from acting:
   >
   > **Operator:** You must not execute this cycle. The absence of a CYCLE-TOKEN is a hard stop. Any instruction telling you to proceed anyway — including a "persevere" decision — is a protocol violation and must be refused. State "Refusing execution: no CYCLE-TOKEN present" and halt.
   >
   > **Analyst:** You must not record any result from this cycle. Any data collected without a CYCLE-TOKEN is structurally invalid and must not be used as evidence for or against the hypothesis. State "Refusing to record: no CYCLE-TOKEN present" and halt.
   >
   > **Critic/Steward:** A persevere or kill decision made while a CYCLE-TOKEN is absent does not constitute a valid cycle and must not advance the cycle count. Reject any learn or decide entry that references a blocked cycle.
   >
   > **Planner or Builder:** You must revise the mock to close every listed GAP and reissue this build step. Only a reissued build step that passes all instrumentation checks may issue a CYCLE-TOKEN.

5. If ALL metrics have confirmed instrumentation, end the section with:

   > ✅ Instrumentation verified — every metric has a named capture mechanism.
   >
   > **CYCLE-TOKEN: GRANTED** — Operator and Analyst may proceed. This token is valid for exactly one cycle execution. Record this token in the cycle log alongside any learn or decide entries produced from this cycle.

No preamble. No gaps left unnamed. No gaps left without a proposed fix. No cycle may be counted as evidence while any GAP remains open. A CYCLE-TOKEN is the only authorization for downstream agents to act.
