The handler calls the seam verbatim with `resolveAiConfig({ aiProvider, aiModel, aiMaxTokens, aiEndpoint })` — flag precedence over `.chanrc` is inherited unchanged from `resolveAiConfig`, and the four `builder` entries are byte-identical to `analyze.builder` (asserted with `toEqual`). +- "MockProvider via flags" in the criteria resolves to this established seam idiom (same as analyze/auto tests); AI-path assertions live on the seam, not the handler, to stay hermetic against `loadConfig`'s `findUpSync` from `process.cwd()`. The no-AI path is covered at the real handler with a stdout spy. +- Cost guard before any AI call: the flow reads `.chan/code.md` and short-circuits when a populated Context exists (`hasContextSection && !isContextEmpty`). `writeContextSection` would no-op anyway, but only after paying for the inspection; the skipped call is asserted via `vi.spyOn(MockProvider.prototype, 'invoke')`. +- All-empty detection is done in-memory on `result.parsed` (every field `''`/`[]`): the empty marker section is still written (the re-runnable state per ADR-0001) and a `warn` tells the user a re-run of `chan init` can populate it. +- AI failures are caught inside the seam and logged as `warn('Context generation failed: ')` — `logger.error`/`fatal` set `process.exitCode = 1` and are never used on the AI path, so init always exits successfully.
