* 1. Identity verification before any SIGTERM. Browse signals on PID

* stale state file pointing at a reused PID doesn't kill an

* unrelated process.
|

*
|
||||
* 2. Refuse-to-kill on version mismatch with active boards. Browse will
|
||||
* restart on version drift; here in-memory boards would be lost, so
|
||||
* we exit 1 with a user-actionable message instead of silent loss.
|

|

* Spawn uses Node's child_process.spawn with detached: true + stdio
|

|

* 1. Serves the comparison board HTML over HTTP at `/`
|

* 2. Prints feedback JSON to stdout (agent reads it)
|

* 3. Stays alive across regeneration rounds (stateful)

* regenerate / reload cycle via HTTP fetch (the same calls the board JS
|

* makes). Proves what design-shotgun and the rest of the design skills
|

* depend on:
|
||||
*
|
||||
* - $D compare --serve attaches to OR spawns a single shared daemon.
|
||||
* - Two boards published into the same daemon get independent paths
|
||||
* under /boards/<id>/ — no port churn, no second process.
|
||||
* - Submit writes feedback.json into the board's sourceDir with
|
||||
* boardId + publishedAt fields the skill can poll for.
|
||||
* - Regenerate writes feedback-pending.json, flips state to
|
||||
* regenerating, /api/progress reflects it.
|
||||
* - /api/reload swaps HTML in place — second GET returns new content.
|
||||
* - Even with two concurrent boards in flight, feedback for one does
|
||||
* not contaminate the other's sourceDir.
|
||||
*
|
||||
* Browser-driven round-trip (feedback-roundtrip.test.ts) covers the same
|
||||
* flow at the click level for the legacy --no-daemon path; this file is
|
||||
* the daemon-path equivalent.
