# Audit Log #23 — M4 Remaining Boundary Emission Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers-extended-cc:subagent-driven-development (bundled cadence).

**Goal:** Close every remaining script-trust-boundary emission gap: sync DB writes/reads via Database.Connection().Execute*/ExecuteReader, Notification Outbox central dispatcher attempts + terminal, site-side Notify.Send submission, and Inbound API middleware. Audit-write failure NEVER aborts the user-facing action across all five new code paths.

**Vocabulary (M3 reality-locked):**
- `AuditKind.DbWrite` (Channel=DbOutbound) for both Execute and ExecuteReader; `Extra` carries `{"op":"write"|"read","rowsAffected":N|"rowsReturned":N}`.
- `AuditKind.NotifyDeliver` for each Notification Outbox attempt; `AuditStatus.Attempted` on attempts, `AuditStatus.Delivered|Failed|Parked|Discarded` on terminal.
- `AuditKind.NotifySend` for site-emit at Notify.Send; `AuditStatus.Submitted`.
- `AuditKind.InboundRequest` for happy-path inbound; `AuditStatus.Delivered`. `AuditKind.InboundAuthFailure` for 401; `AuditStatus.Failed`.
- `AuditStatus.Failed` replaces "PermanentFailure" / "TransientFailure" terminal wording throughout.

**Bundles:**
- Bundle A — DB sync emissions (T1, T2)
- Bundle B — NotificationOutbox central emissions (T3, T4, T5)
- Bundle C — Site Notify.Send emission (T6)
- Bundle D — Inbound API audit middleware (T7, T8)
- Bundle E — Integration tests (T9, T10, T11, T12)
- Final cross-bundle review + merge

Each task follows the M2 Bundle F / M3 Bundle E emission pattern: capture timing, build AuditEvent with provenance, write via try/catch that swallows + logs, never propagate audit failure to the user-facing action. Mirror M2's ScriptRuntimeContext wrapper pattern where the emission is script-context-aware.

Integration tests go in `tests/ScadaLink.AuditLog.Tests/Integration/` (component-level per M2 Bundle H + M3 Bundle G — the existing IntegrationTests factory disables Akka).
