780. **`classify_error_kind` arm ordering bug: `"failed to restore session: legacy session is missing workspace binding: ..."` classified as `session_load_failed` instead of `legacy_session_no_workspace_binding`** — dogfooded 2026-05-27 on `364e7909`. The full error message from `resume_session` prepends `"failed to restore session: "` before `"legacy session is missing workspace binding: ..."`. The `contains("failed to restore session")` arm at line 278 matched first, returning `session_load_failed`; the more specific `legacy_session_no_workspace_binding` arm at line 282 was never reached. Same shadowing existed for `no_managed_sessions`. Fix: reordered the three arms — specific cases (`no_managed_sessions`, `legacy_session_no_workspace_binding`) before the generic `session_load_failed` catch-all. Unit test updated to assert corrected discriminants, plus new assertion covering the full prefixed message that exposed the bug. 40 CLI contract tests pass.

781. **`api_http_error` was a single bucket for all HTTP errors; 401 auth and 429 rate-limit returned `hint:null` with no distinction** — dogfooded 2026-05-27 on `d9844cfe`. `classify_error_kind` had a single `api_http_error` arm for all API failures. 401 Unauthorized and 429 rate-limit errors emitted `error_kind:"api_http_error"` + `hint:null`, making it impossible for automation to distinguish auth misconfiguration from transient rate-limiting. Fixes: (1) added `api_auth_error` sub-classifier arm for 401/Unauthorized/authentication_error messages; (2) added `api_rate_limit_error` arm for 429/rate_limit messages; (3) added `fallback_hint_for_error_kind()` that derives a stable hint from the error kind when `split_error_hint` returns `None` (API layer never emits `\n`-delimited hints); (4) main JSON error emission path now calls `fallback_hint_for_error_kind` as fallback. Auth errors now return `api_auth_error` + env-var hint; rate-limit returns `api_rate_limit_error` + retry hint. Unit tests updated. 40 CLI contract tests pass.

782. **`claw acp start` returned `error_kind:"unsupported_acp_invocation"` + `hint:null` — remediation text was on same line** — dogfooded 2026-05-27 on `16c1117a` (pinpoint by Gaebal-gajae). The error message `"unsupported ACP invocation. Use `claw acp`, `claw acp serve`, `claw --acp`, or `claw -acp`."` had no `\n` delimiter, so `split_error_hint` returned `hint:null`. Automation could tell ACP was unsupported but could not read the remediation structurally. Fix: inserted a `\n` before the remediation text: `"unsupported ACP invocation. Use ... claw -acp.\nACP/Zed editor integration is currently a discoverability alias only; ..."`. Integration test `acp_unsupported_invocation_has_hint_782` added. 41 CLI contract tests pass.
