Self-pull fix:

FetchWorkspaceChannelContext in manager.go silently dropped two error paths:

1. rows.Next() returning false due to an iteration error (not just no rows) — now logged via rows.Err().
2. rows.Scan failing — now logged before returning empty string.

Both paths preserve the existing fail-soft behavior (return "" so cron prompts proceed without Slack ambient context).

Self-pull fix: `FetchWorkspaceChannelContext` in `manager.go` silently dropped two error paths: 1. `rows.Next()` returning false due to an iteration error (not just no rows) — now logged via `rows.Err()`. 2. `rows.Scan` failing — now logged before returning empty string. Both paths preserve the existing fail-soft behavior (return `""` so cron prompts proceed without Slack ambient context).

fix(channels,messagestore): log json.Unmarshal errors instead of silently dropping them ... e179485a0e

Four production sites were ignoring json.Unmarshal return values:

- channels.go List+Webhook: corrupt JSON rows would produce empty config/allowed_users without any signal.

- manager.go FetchWorkspaceChannelContext: empty config would fall through to DecryptSensitiveFields failure, masking the root cause.

- messagestore extractFilesFromResponse: _ = json.Unmarshal discarded parse errors on the probe wrapper.

All four now log the error at the point of failure so operators can spot data-corruption or schema-drift incidents.

fix(channels,messagestore): preserve previous flow after logging json.Unmarshal errors ... 212842bc3f

Addresses review feedback on PR #1899: the stated scope is observability/
no behavior change, but the initial diff changed control flow on unmarshal
failures (continue/return instead of proceeding with zero values).

This revision keeps the error logging but restores the previous flow so
that List/Webhook proceed with nil config/allowedUsers and
FetchWorkspaceChannelContext proceeds to DecryptSensitiveFields, exactly
as the bare `_ = json.Unmarshal` did before.

fix(channels): add rows.Err() and scan error logging in FetchWorkspaceChannelContext ... 62cbf57cb2

The FetchWorkspaceChannelContext function in manager.go was silently
dropping two error paths:

1. When rows.Next() returned false due to an iteration error (not just
   no rows), we returned "" without logging the underlying DB error.

2. When rows.Scan failed, we returned "" without logging what went
   wrong, making channel-context debugging harder.

This change adds log.Printf for both paths while preserving the
existing fail-soft behavior (return empty string so cron prompts
proceed without Slack ambient context).

LGTM — rows.Err and scan failures are now logged while preserving the existing fail-soft return path, and the unmarshal logging preserves prior continuation behavior.

PM 2nd-approve per direct CTO request. Standard Go database/sql error-handling idiom: rows.Err() after rows.Next(), named error var on rows.Scan, plus error logging. Fail-soft behavior preserved (still returns empty string on errors).
