Security-sensitive batch, handled main-thread for careful judgment on secret-leak and pepper-bypass paths. Secret leak / pepper bypass: - CD-016 (pepper bypass): InboundApiRepository's GetApiKeyByValueAsync no longer hashes the candidate with the unpeppered ApiKeyHasher.Default — ctor takes a lazy Func<IApiKeyHasher> accessor (lazy so test composition roots without a pepper still bring up the repository), and the DI registration wires sp.GetService<IApiKeyHasher>() so the production peppered hasher matches the stored KeyHash. Regression test asserts positive (peppered roundtrip) AND negative (Default hasher misses the same key — proving the lookup uses the injected hasher). - MgmtSvc-020 (SMTP credential leak): UpdateSmtpConfig/ListSmtpConfigs now project through SmtpConfigPublicShape so the response payload and audit-row afterState never carry the Credentials field — only a HasCredentials bool. The SMTP password / OAuth2 client secret no longer leaves the Admin-only UpdateSmtpConfig boundary the caller already supplied it to. Redaction: - AuditLog-008 (test-fixture under-redact): new SafeDefaultAuditPayloadFilter (stateless singleton) does HTTP header redaction for the always-sensitive defaults (Authorization, X-Api-Key, Cookie, Set-Cookie). FallbackAuditWriter, CentralAuditWriter, and AuditLogIngestActor (both ingest paths) default to it instead of null — composition roots that bypass AddAuditLog can no longer write unredacted auth headers to the audit store. - NotifService-025 (over-mask): CredentialRedactor.Scrub now only masks the last colon-separated component (password / clientSecret) AND only if it's >= 12 chars (typical password heuristic). Short user names like "root" no longer become global redaction tokens that eat unrelated diagnostic text. The full packed string is always masked regardless of length. 3 new negative tests pin the no-over-mask contract. Audit-row correctness / fail-loud: - InboundAPI-025: Program.cs UseWhen predicate now excludes /api/audit, /api/management, /api/centralui, /api/script-analysis AND requires POST — the AuditWriteMiddleware no longer emits spurious ApiInbound rows for audit-log query/export endpoints (write-on-read recursion broken). - ESG-021: ApplyAuth now logs Warning (not silent) on empty AuthConfiguration for apikey/basic, unknown AuthType, and malformed Basic config. AuthConfiguration value NEVER logged. AuthType=none remains silent (documented unauthenticated sentinel). - Security-021: AddSecurity now logs a startup Warning when RequireHttpsCookie=false — an HTTP-only deployment that previously transmitted the cookie-embedded JWT silently in cleartext is now audible in the log. Defensive: - CD-021: SwitchOutPartitionAsync's monthBoundary format string now yyyy-MM-dd HH:mm:ss.fffffff (datetime2(7) precision) so a future sub-second / non-midnight boundary doesn't silently round to the wrong partition. Plus reconciled stale per-module Open-findings counters that had drifted from earlier sessions (AuditLog, CD, ESG, IAPI, MgmtSvc, NotifService, Security). Build clean; all affected test projects green (Host 208, ConfigDB 242, ESG 69, IAPI 151, MgmtSvc 100, NotifService 55, Security 85, AuditLog 247/248 — 1 pre-existing date-sensitive integration test flake on PartitionPurgeTests, unrelated). README regenerated: 46 open (was 54).
Code Reviews
Comprehensive, per-module code reviews of the ScadaLink codebase. Each module (one
buildable project under src/) has its own folder containing a findings.md. This
README is the aggregated index — the single place to see all outstanding work.
Generated by
regen-readme.pyfrom the per-modulefindings.mdfiles. Do not edit by hand — edit the findings files and re-run the script.
How it works
- Reviews are performed one module at a time against a fixed checklist.
- Every finding is recorded in the module's
findings.mdwith a severity and status. - Findings are never deleted — they are closed by changing their status, keeping a full audit trail.
- This README aggregates every pending finding (
Open/In Progress) across all modules.
See REVIEW-PROCESS.md for the full procedure: the review checklist, severity definitions, finding format, and how to mark items resolved.

findings.md (see REVIEW-PROCESS.md §4–§5). Full detail —
description, location, recommendation — lives in the module's findings.md.
