docs(code-review): record SMS-feature review findings + reconcile NotificationService doc

Per-module code review of the SMS notifications feature (reviewed at d6ead8ae) following
code-reviews/REVIEW-PROCESS.md. 19 findings across 7 modules — 1 High, 5 Medium, 13 Low:

- ManagementService-024 (High): provider-config updates Admin-gated to match the UI.
- ConfigurationDatabase-025, CentralUI-034/035, ManagementService-025 (Medium): migration
  data-safety guard, type-aware recipient badge, FromNumber-optional (Messaging-Service-only),
  empty-token-clear guard.
- Remaining Low: secret-encryption + diff + dispatch + factory + contract tests, truncation,
  ctor guard, reserved retry-field docs.
- Won't Fix: Transport-015/016 (shared repo-wide import patterns, not SMS-specific),
  Commons-026 (breaking ergonomics-only change). Deferred: ConfigurationDatabase-027 (live-SQL
  migration test).

All findings closed (0 pending). README.md regenerated; Component-NotificationService.md
updated for the FromNumber-optional + reserved-retry-fields outcomes.

#### Re-review 2026-06-19 (commit `d6ead8ae`) — SMS notifications feature
Per-module review of the `ManagementActor` SMS surface: the SMS/SMTP provider-config command gating,
`HandleUpdateSmsConfig`, and the `SmsConfigPublicShape` secret projection. The secret-redaction chain
(`SmsConfigPublicShape` exposes `HasAuthToken` only; the AuthToken never reaches the response or audit
afterState) is correct and tested. One High authorization finding, one Medium secret-clear footgun, one
Low stale comment; all Resolved.
### ManagementService-024 — SMS/SMTP provider-config updates were Designer-gated despite Admin-only UI
| | |
|--|--|
| Severity | High |
| Category | Security |
| Status | Resolved |
| Location | `src/ZB.MOM.WW.ScadaBridge.ManagementService/ManagementActor.cs:189-190` |
**Description**
`UpdateSmsConfigCommand` (and the pre-existing `UpdateSmtpConfigCommand`) were placed in the Designer
arm of `GetRequiredRole`, but both the `/notifications/sms` and `/notifications/smtp` Central UI pages
enforce `RequireAdmin`. This split-brain let a Designer who is blocked in the UI still rotate a
production credential (the Twilio Auth Token / SMTP password) via the CLI / Management API. The design
(D8) specifies SMS config management as Admin-only.
**Recommendation**
Move `UpdateSmsConfigCommand` (and `UpdateSmtpConfigCommand`, whose UI page is also RequireAdmin) to the
Administrator arm so the actor gate matches the UI.
**Resolution**
Resolved 2026-06-19 (commit `cd8e4872`): both update commands moved to the Administrator arm. Locked by
`UpdateSmsConfig_WithDesignerRole_ReturnsUnauthorized` and updated success-case tests (commit `a9393c89`).
### ManagementService-025 — Empty-string `--auth-token` silently clears the stored Twilio token
| | |
|--|--|
| Severity | Medium |
| Category | Security |
| Status | Resolved |
| Location | `src/ZB.MOM.WW.ScadaBridge.ManagementService/ManagementActor.cs:1859` |
**Description**
`HandleUpdateSmsConfig` used `if (cmd.AuthToken is not null)` for preserve-if-omitted. An explicit empty
/ whitespace `--auth-token ""` passes the null check and overwrites the stored token with empty, silently
clearing the credential and 401-ing every subsequent send. A Twilio Auth Token is always required, so an
empty value is never a valid rotation.
**Recommendation**
Guard on `IsNullOrWhiteSpace` so an empty token is treated as omitted (preserve). (SMTP `Credentials`
keeps its null-only guard, since empty may be valid for anonymous SMTP.)
**Resolution**
Resolved 2026-06-19 (commit `cd8e4872`): the guard is now `!string.IsNullOrWhiteSpace(cmd.AuthToken)`.
Locked by `UpdateSmsConfig_WithEmptyAuthToken_PreservesExistingToken` (commit `a9393c89`).
### ManagementService-026 — Stale "Admin-only" comment on `HandleListSmtpConfigs`
| | |
|--|--|
| Severity | Low |
| Category | Documentation & comments |
| Status | Resolved |
| Location | `src/ZB.MOM.WW.ScadaBridge.ManagementService/ManagementActor.cs:1788-1790` |
**Description**
The comment on `HandleListSmtpConfigs` called the `UpdateSmtpConfig` path "Admin-only", which did not
match its (then) Designer gating; the SMS counterpart comment said "Designer-gated". The two were
inconsistent.
**Recommendation**
Make the comments accurate after fixing the gating.
**Resolution**
Resolved 2026-06-19 (commit `cd8e4872`): with both update commands moved to Administrator (MS-024), the
SMTP "Admin-only" comment is now accurate and the SMS list comment was updated to "Admin-only".
