SOP Checklist

• Comprehensive testing performed: Provisioner unmarshal path tested with invalid JSON.
• Local-postgres E2E run: N/A — pure handler/tooling change, covered by existing tests
• Staging-smoke verified or pending: scheduled post-merge
• Root-cause not symptom: json.Unmarshal and io.ReadAll errors were silently dropped, hiding provisioning failures.
• Five-Axis review walked: correctness / readability / architecture / security / performance
• No backwards-compat shim / dead code added: yes — no shims, only defensive error handling
• Memory/saved-feedback consulted: N/A — new hygiene fix from static analysis

fix(provisioner): check io.ReadAll + json.Unmarshal errors in CP client ... b4a0f8b74d

Start() silently ignored io.ReadAll and json.Unmarshal errors when
reading the control plane provision response. A network hiccup or
malformed CP response would be swallowed, producing a misleading
"unstructured body" error instead of the real read/unmarshal failure.

Stop() also ignored io.ReadAll on the error path. Now surfaces the
read error explicitly so ops can distinguish "CP returned 500" from
"connection dropped mid-body".

fix(provisioner): surface json.Unmarshal error on malformed 201 response ... 156a9623be

CR2 from review #5552: Start() previously logged (or ignored) json.Unmarshal
errors but still treated malformed 201 Created CP provision responses as
success, returning an empty instance_id with nil error.

Change the logic so that on HTTP 201, a json.Unmarshal failure returns an
error instead of proceeding with an empty instance ID. Non-201 paths keep
the existing byte-count fallback behaviour.

Added TestStart_Malformed201SurfacesError covering the malformed-201 case.

Approved — read/unmarshal errors are now surfaced on the CP provisioner paths, with a focused malformed-201 regression test. CI is still pending, but the diff is correctness-only and low risk.
