So the one route that exists *specifically* to re-verify a password before a privileged action was the one route emitting nothing.\\n\\nThe emit logic moved out of `IdentityProvider` into a shared `AuthSecurityEventLogger` injected into both, rather than being duplicated. `IssueAsync` now fires `LoginFailed` on all three unsuccessful branches and `AccountLockedOut` off the previously-discarded bool.\\n\\nBoth invariants preserved and tested: `LoginFailed` carries no user id or email on any branch (no identity-existence oracle in telemetry), and `AccountLockedOut` fires exactly once on the threshold-crossing attempt.

A hardcoded list would have been the same bug waiting for the next route.\\n\\nThe client-errors exclusion is deliberate and preserved with its rationale: #217 guards log-pipeline volume, not a credential, so its rejections stay plain 429s.

The three P1s turned out to be one theme: the new security-event coverage stopped at `/auth/login` and `/auth/refresh` and missed `/auth/step-up` and `/auth/change-password` — the *privileged* password-checking routes. Fixed at the root by keying the rate-limit event off the attached policy rather than a path list, so it can't drift again as routes are added.\\n\\nThe connection-string one was the sharpest: the pattern didn't merely mishandle quoted values, it failed to match them at all, so the whole credential reached the sink.

Both nest a quantifier inside a quantifier, and while both happen to be unambiguous, that is a judgement call I am not willing to put on the path of caller-controlled free text from the anonymous `/client-errors` endpoint (#217), where getting it wrong is a CPU DoS rather than a cosmetic bug. The code scan is one forward pass with a cursor that never moves backwards — provably O(n), with no backtracking to reason about at all. It also buys a property no regex alternative had: an **unterminated** quoted value now fails CLOSED (redacts to end of string) instead of simply not matching and passing the tail through.\\n\\nSame inputs after the fix:\\n\\n```\\nHost=db;Password=\\\"alpha\\\"\\\"omega;tail\\\"; -> Host=db;Password=[REDACTED];\\nHost=db;Password='alpha''omega;tail'; -> Host=db;Password=[REDACTED];\\nHost=db;Pwd=\\\"a\\\"\\\"b;c\\\";Pooling=true -> Host=db;Pwd=[REDACTED];Pooling=true\\nHost=db;Password=\\\"unterminated secret -> Host=db;Password=[REDACTED]\\n```\\n\\n**False-positive guards re-verified**, since this file has corrupted Serilog's own `{SourceContext}` once before: `A_guid_and_a_dotted_namespace_are_untouched_by_the_widened_connection_string_pattern`, `A_three_segment_dotted_namespace_is_not_mistaken_for_a_jwt`, and `Guid_valued_properties_are_never_altered_by_the_phone_number_pattern` (200 random GUIDs) all still pass — with no `password=`/`pwd=` prefix the scanner never engages at all.\\n\\n**Tests + mutation check.** New `A_doubled_quote_inside_a_quoted_credential_does_not_end_the_redaction` (4 cases: `\\\"`/`'` × `Password`/`Pwd`) asserts the whole value is gone with nothing trailing, plus `An_unterminated_quoted_credential_is_redacted_to_the_end_of_the_string`.

You are right that the PR overclaimed: the enricher had zero references to `logEvent.Exception`, so every `logger.LogError(ex, ...)` — including the `Auth.RefreshRevocationFailed` event this PR itself added, and Npgsql exceptions whose messages routinely carry the connection string — reached the sinks unredacted.\\n\\n**Options considered, and why the sink wrapper won.**\\n\\n- *Redact at the throw/log sites* — rejected. Unenforceable: nothing stops the next `LogError(ex, ...)`, and the exceptions that matter most (Npgsql's) are thrown by code we don't own.\\n- *`ITextFormatter`* — rejected. It only protects sinks configured to use that formatter. Our Console sink is configured with `outputTemplate`, not `formatter`, and any DI-registered sink (`ReadFrom.Services`) would be untouched. It is a partial control that reads like a total one.\\n- *`ILogEventFilter`* — not viable. `IsEnabled(LogEvent)` returns a bool; it can mutate properties but cannot substitute the event, which is the same wall the enricher hits.\\n- *Wrapping `ILogEventSink`* — chosen. A sink is the only pipeline element that receives an event and decides what the *next* element sees.\\n\\n`ExceptionRedactingSink` rebuilds the `LogEvent` around a `RedactedException` stand-in whose `ToString()` (the `{Exception}` output token, and Compact JSON's `@x`) and `Message` carry the redacted text. When redaction changes nothing the original instance is forwarded, so an ordinary exception keeps its real CLR type, stack trace and inner-exception chain.\\n\\n**A wrapper is only a control if no sink can be registered beside it**, so `RedactingLoggerPipeline` builds the logger in two stages:\\n\\n- **stage 1** — the logger callers hold. Owns only the settings that must be evaluated where an event is *created* (`MinimumLevel`, per-source `Override`, `Destructure`), and has exactly **one** sink: the wrapper. There is no supported way to attach another sink to it.\\n- **stage 2** — a sub-logger holding **every** sink from **both** sources the app supports: `Serilog:WriteTo` in configuration (how `appsettings.json` declares Console) and `ILogEventSink` registrations in DI (`ReadFrom.Services`, the #214 tap). Plus the configured enrichers and *then* the property redactor, in that order, so log-context properties are still redacted. `MinimumLevel.Verbose()` is applied after the configuration is read, because a sub-logger re-checks a forwarded event against its own flat level and does **not** re-apply the override map — without it, an event a `MinimumLevel:Override` deliberately enabled would be silently dropped.\\n\\nConsequence: a sink added later, by an operator through config or by a future component through DI, is covered automatically.\\n\\n**What is NOT covered — stated explicitly rather than implied**, and now written into `docs/security/log-redaction-policy.md`:\\n\\n1. A component logging through a Serilog logger it constructed **itself** rather than obtaining from this host's DI container. Nothing in this repo does that today; a future addition that did would bypass the pipeline entirely.\\n2. The **OpenTelemetry** exporter path (`Otlp:*`) carries traces and metrics, not Serilog log events. Exception detail recorded on an *activity/span* by the ASP.NET Core or EF Core instrumentation does not pass through this pipeline and is not redacted by it.\\n3. The pre-existing residual gap: a value baked into a message by C# string interpolation rather than a template hole.\\n\\n**Tests — deliberately not a helper-function test**, which is exactly the shape that would have passed while this gap stayed open. `RedactingLoggerPipelineTests` builds the pipeline the way the host builds it and asserts an exception carrying a runtime-generated credential arrives redacted at (a) a sink **declared in `Serilog:WriteTo`** and instantiated by Serilog.Settings.Configuration — the same mechanism `appsettings.json` uses for Console, the test never hands the pipeline a sink instance — and (b) a DI-registered sink. Plus: an innocuous exception arrives as the *same instance*; `MinimumLevel` still governs `IsEnabled` on the logger callers hold; a per-source override still reaches the sinks; property redaction still applies to both sinks.\\n\\n**Mutation-checked, each reverted and restored:**\\n\\n| mutation | result |\\n|---|---|\\n| sink forwards `logEvent.Exception` unchanged | 2 failed (config-declared **and** DI sink) |\\n| always substitute, never pass the original through | 1 failed (`An_exception_with_nothing_sensitive_reaches_the_sink_completely_unaltered`) |\\n| drop stage 2's `MinimumLevel.Verbose()` | 1 failed (`A_per_source_minimum_level_override_still_reaches_the_sinks`) |\\n| stage 1 stops reading level settings | 2 failed (both level tests) |\\n| drop the property redactor from stage 2 | 1 failed (`Property_redaction_still_applies_on_the_way_to_every_sink`) |\\n\\nNo survivors.

Verified independently before changing anything: the owner lookup at `IdentityProvider.cs:508-511` sat outside every `try`, and `RevokeByHashAsync` was the only thing wrapped — so a read failure meant the bulk update never ran *and* nothing was logged. Proven by fault injection, not by reading: arming an interceptor on the `SELECT ... refresh_tokens` produced zero `Auth.RefreshRevocationFailed` events while the call still threw.\\n\\n**Fix.** One boundary now spans the whole sequence — owner lookup, step-up grant record (#308/#336), bulk update — and the update *inside* it is the raw statement (`RevokeByHashCoreAsync`), never a second `RunRevocationAsync` wrapper, so a failing update still emits **exactly one** event rather than two. `RunRevocationAsync` gained a `Func` overload because the owner is only known once the lookup this boundary now covers has succeeded; the three call sites that do know it up front keep the `Guid?` overload unchanged.

The regex now matches only the KEY; the value's extent is parsed in code following ADO.NET's quoting rules.

Not abandoned, and no further work is being done on it for now.\\n\\nWhere it stands, for whoever picks it up:\\n\\n- All 8 codex findings across two rounds are addressed at `94a4b88`; **1163 tests green** (283 domain + 114 application + 766 integration), build 0 warnings / 0 errors, every fix mutation-checked.\\n- CI is green except **CodeQL**, whose 3 alerts are all in `LogRedactionTests.cs` — the lines that deliberately log a generated secret to prove the redactor strips it (`Guid.NewGuid()` values, in-memory sink). Nothing was renamed or suppressed to make them go away; that call belongs to the maintainer. `used_in_tests` is the fitting dismissal reason if wanted.\\n\\n**The reason a slower look is warranted.** This PR started as \\\"redact logs, emit security events\\\" and is now **+2337 lines across 21 files**, because round-2's exception-redaction finding could not be fixed inside an enricher — `LogEvent.Exception` is get-only and an `ILogEventEnricher` cannot replace it. Closing it properly required a two-stage logger pipeline (`RedactingLoggerPipeline`): stage 1 holds level/override settings and exactly one sink; stage 2 owns every configured and DI-registered sink. That is a change to how *every* log line in the app is dispatched, arriving inside a PR nominally about redaction. It is well covered — six mutation axes including per-source overrides — but it deserves review on its own terms, and splitting the pipeline restructure into its own PR is a reasonable option.\\n\\n**Two limits that narrow the \\\"process-wide redaction\\\" claim**, both written into `docs/security/log-redaction-policy.md` rather than glossed:\\n\\n1. **OTLP is not covered.** Traces and metrics never pass through the Serilog pipeline, so exception detail recorded on a *span* by the ASP.NET Core / EF Core instrumentation is unredacted. For a deployment exporting traces, that is the more likely destination than the console sink.\\n2. A component constructing its own Serilog logger instead of taking one from DI would bypass the pipeline. Nothing does this today; nothing enforces it either.\\n\\nAlso worth carrying forward: #273's issue text asks for sink selection, retention, access control and a cost budget. Those are deliberately **out of scope here** per the host-agnostic boundary and belong to the deployment/ops repo — so #273 should not be auto-closed by this PR.\\n\",\"path\":null,\"side\":null,\"line\":null}{\"type\":\"pull_request_comment\",\"body\":\"Cross-posting from #405 (`feat(obs): emit compact JSON logs to stdout in Production`, #404), which is green and ready to merge and interacts with this PR. **Correcting my own note on #273 first: the interaction is smaller than I implied there, but the part that remains is worth a test here.**\\n\\n## What does NOT break\\n\\nI warned on #273 that `LogRedactionTests` should be re-run against the JSON formatter. Having read it, that was overstated — the enricher rewrites the **LogEvent property** (`ScalarOf(e, \\\"Password\\\") == \\\"[REDACTED]\\\"`), not rendered output, so it sits upstream of any formatter and is format-agnostic by construction. #405 swaps the Production formatter and changes nothing about that. Both PRs compose: enricher redacts, then the formatter serializes whatever survived.\\n\\n## What changes, and it is not nothing\\n\\n#405 changes the **blast radius of a redaction miss**, not the mechanism.\\n\\nBefore it, Production rendered `[{Timestamp} {Level}] [{TraceId}:{SpanId}] {Message:lj}{Exception}` and **silently dropped every property the template did not name**. So a property this enricher does not cover was invisible anyway — the template was an accidental second layer. After #405, compact JSON serializes **every** property, so this enricher's coverage becomes the only thing between a property and the collector.\\n\\nConcretely for the `/client-errors` case this PR fixes: `Stack` and `ComponentStack` are deliberately **not** in `ForbiddenPropertyNames` (the file's own comment at the top says as much for Message/Route/Stack), so they rely entirely on the six content patterns. Walking those against what a browser stack actually contains — URLs with query strings:\\n\\n| shape in a stack URL | caught by |\\n|---|---|\\n| `?password=hunter2` | ✅ `ConnectionStringCredentialKeyPattern` — `\\\\b(password\\\\|pwd)\\\\s*=\\\\s*` matches a query key too |\\n| `?token=eyJhbGci…` | ✅ `JwtPattern` — Cluckwork access tokens are JWTs, so they start `eyJ` |\\n| `https://user:pass@host/…` | ✅ `UriCredentialPattern` |\\n| `?api_key=`, `?access_token=`, `?code=…`, `?sig=…` | ❌ none — not an email, not `eyJ`, no literal `Bearer `, not `password=`, not userinfo, not a phone |\\n\\nThat last row is the gap #405 makes reachable. It was unreachable before only because the template dropped the property. Worth at least one regression test with an opaque query-string credential, and possibly a generic `[?&](token\\\\|api[_-]?key\\\\|access_token\\\\|auth\\\\|sig\\\\|code)=` key pattern beside the existing `password|pwd` one — the key name is the reliable signal when the value has no recognisable shape.\\n\\nVolume is the other half: ~16 KB of anonymous, caller-chosen text per accepted report now reaches stdout, where before roughly 2.5 KB of sanitized prose did.\\n\\n## Sequencing\\n\\nThe two PRs share exactly one file — `tests/Cluckwork.Api.IntegrationTests/ClientErrorReportTests.cs` — where #405 only rewrites a comment its own change made false (the old text claimed the stacks \\\"ride as structured properties the console line never shows\\\", which stops being true under JSON). Trivial conflict whichever way round.\\n\\nIf #405 merges first, the exposure is live until this lands, which is the main argument for taking this out of draft. There is no production deployment yet (#244 is the pre-go-live audit), so nothing is shipping these logs to a real collector today — but that is a fact about timing, not a property of the code.\",\"path\":null,\"side\":null,\"line\":null}{\"type\":\"pull_request_comment\",\"body\":\"#### ⚠️ GitGuardian has uncovered 1 secret following the scan of your pull request.\\n\\nPlease consider investigating the findings and remediating the incidents.

🛠 Guidelines to remediate hardcoded secrets

\\n
\\n\\n1. Understand the implications of revoking this secret by investigating where it is used in your code.\\n2. Replace and store your secret safely. [Learn here](https://blog.gitguardian.com/secrets-api-management?utm_source=product&utm_medium=GitHub_checks&utm_campaign=check_run_comment) the best practices.\\n3. Revoke and [rotate this secret](https://docs.gitguardian.com/secrets-detection/secrets-detection-engine/detectors/generics/generic_password#revoke-the-secret?utm_source=product&utm_medium=GitHub_checks&utm_campaign=check_run_comment).\\n4. If possible, [rewrite git history](https://blog.gitguardian.com/rewriting-git-history-cheatsheet?utm_source=product&utm_medium=GitHub_checks&utm_campaign=check_run_comment). Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.\\n\\nTo avoid such incidents in the future consider\\n\\n- following these [best practices](https://blog.gitguardian.com/secrets-api-management/?utm_source=product&utm_medium=GitHub_checks&utm_campaign=check_run_comment) for managing and storing secrets including API keys and other credentials\\n- install [secret detection on pre-commit](https://docs.gitguardian.com/ggshield-docs/integrations/git-hooks/pre-commit?utm_source=product&utm_medium=GitHub_checks&utm_campaign=check_run_comment) to catch secret before it leaves your machine and ease remediation.\\n\\n\\n
