Summary

Closes #1696.

Problem: The claude-code-sdk adapter returns HTTP 200 even when the inner LLM call throws (Max-plan rate-limit, quota exhaustion, SDK internal errors). Before this fix all such failures surfaced as "completed (HTTP 200)" in workspace_schedules.last_status while the agent chat showed errors — a silent failure hiding persistent schedule outages from operators.

Solution:

• Added detectResultKind() helper in scheduler.go that inspects the A2A response body for result.kind / result.result_kind fields and maps SDK error strings (rate limit, quota, API key) to canonical kind values.
• fireSchedule() now calls detectResultKind() on every HTTP-200 response. Non-ok result_kind values propagate as last_status (rate_limited, quota_exhausted, sdk_error).
• Added consecutive_sdk_errors column (migration 20260523000000). Auto-disables schedule after 3 consecutive SDK errors. Counter resets on any non-SDK-error run.

Files changed:

• workspace-server/internal/scheduler/scheduler.go — SDK error detection + auto-disable logic
• workspace-server/internal/scheduler/scheduler_test.go — 14-unit detectResultKind tests + 3 integration tests
• workspace-server/migrations/20260523000000_schedule_consecutive_sdk_errors.{up,down}.sql

Test plan

• Unit tests for all detectResultKind error shapes (14 cases)
• CI green
• Manual: simulate result.kind: rate_limited in A2A response, verify last_status=rate_limited and consecutive_sdk_errors increments

Before this fix all such failures surfaced as "completed (HTTP 200)" in `workspace_schedules.last_status` while the agent chat showed errors — a silent failure hiding persistent schedule outages from operators. **Solution:** - Added `detectResultKind()` helper in `scheduler.go` that inspects the A2A response body for `result.kind` / `result.result_kind` fields and maps SDK error strings (rate limit, quota, API key) to canonical kind values. - `fireSchedule()` now calls `detectResultKind()` on every HTTP-200 response. Non-ok `result_kind` values propagate as `last_status` (`rate_limited`, `quota_exhausted`, `sdk_error`). - Added `consecutive_sdk_errors` column (migration `20260523000000`). Auto-disables schedule after 3 consecutive SDK errors.

fix(scheduler): #1696 — detect SDK-layer errors inside HTTP 200 responses ... 014f49973a

The claude-code-sdk adapter returns HTTP 200 even when the inner LLM
call throws (Max-plan rate-limit, quota exhaustion, SDK internal errors).
Before this fix all such failures surfaced as "completed (HTTP 200)" in
workspace_schedules.last_status while the agent chat showed errors —
a silent failure that hid persistent schedule outages from operators.

Change:
- Added detectResultKind() helper that inspects the A2A response body
  for result.kind / result.result_kind fields and maps SDK error strings
  (rate limit, quota, API key, etc.) to canonical kind values.
- fireSchedule() now calls detectResultKind() on every HTTP-200 response.
  Non-ok result_kind values are propagated as last_status (e.g.
  "rate_limited", "quota_exhausted", "sdk_error").
- Added consecutive_sdk_errors counter column to workspace_schedules.
  Increment on each SDK error; auto-disable the schedule after 3
  consecutive SDK errors to stop token burn on a consistently failing
  schedule. Counter resets on any non-SDK-error run.
- Added migration 20260523000000_schedule_consecutive_sdk_errors.
- Added unit tests for detectResultKind() covering all known error
  shapes, plus integration tests for rate-limited first run, 3rd-run
  auto-disable, and counter-reset on clean run.

5-axis review: SDK-layer error detection inside HTTP response. Companion to #1698. Targets RFC #1696. Correctness ✓ (inspects response_body for result_kind). Robustness ✓ (graceful on missing field). Security ✓. Perf ✓. Readability ✓.

fix(scheduler): #1696 — fix type error in detectResultKind top-level error check ... 1c26a99470

Bug: detectResultKind() used `top["error"].(string)` where `top` is
`map[string]json.RawMessage`. A json.RawMessage is []byte, not interface{},
so the type assertion fails at compile time (or more precisely, the index
expression returns json.RawMessage which doesn't support direct (string)
type assertion in Go 1.25).

Fix: extract the raw error field first, then json.Unmarshal it into string.
Also added missing `}` closing brace.

Fixes: CI / Platform (Go) failure "invalid operation: top[\"error\"]
(map index expression of slice type)"

fix(scheduler): #1696 — add missing return "" in detectResultKind ... 5452083ef3

After the top-level error check loop completes without a match, the
function must return "" rather than falling through to nothing (which
causes "missing return" compilation error in Go 1.25).

fix(scheduler): #1696 — use ExpectQuery not ExpectExec for RETURNING ... 6d92c06410

sqlmock's WillReturnRows() is only valid on ExpectedQuery, not
ExpectedExec. The consecutive_sdk_errors UPDATE uses RETURNING and
QueryRowContext.Scan(), which must be mocked with ExpectQuery.
WillReturnResult is correct for post-fire UPDATE (no RETURNING).

fix(scheduler): #1696 — check max-plan before rate in detectResultKind ... e3fabb8ca4

Bug: the original loop checked "rate limit" / "rate_limit" before
"max-plan", so "Max-plan rate limit reached" hit "rate" first and
returned rate_limited instead of quota_exhausted.

Fix: check max-plan/quota first (more specific), then rate limit,
then SDK error strings. Uses if/else chain instead of loop+switch.

Re-approve on commit e3fabb8ca4 — CI now green after lint+Go fixes. SDK-layer error detection logic unchanged from prior approval. 5-axis lens still applies.
