Closes #4231

Summary

  • expose module-aware console output through IPipelineContext.Console
  • split plain text (WriteLine) from Spectre markup (WriteMarkupLine)
  • move IConsoleWriter into ModularPipelines.Logging and make the raw implementation internal
  • update call sites, API baselines, release notes, docs, and focused tests

Validation

  • ModularPipelines.slnx Release build: 0 warnings, 0 errors
  • ConsoleWriterTests: 3/3
  • ModuleLoggerTests: 12/12
  • ContextHierarchyTests: 6/6
  • SecretObfuscatorTests: 3/3
  • PipelineCommandLineTests: 77/77
  • scoped whitespace verification: passed

Full ModularPipelines.Tests.slnf format verification hit the agent 2 GB guard while reporting unrelated existing formatting debt in ScaleTests.cs and ZipCentralDirectory.cs; touched-file whitespace checks pass. The build pipeline was not run per repository agent constraints.

📝 Walkthrough

Walkthrough

This change adds module-aware console output through pipeline contexts, moves IConsoleWriter to ModularPipelines.Logging, replaces LogToConsole with separate plain-text and markup methods, updates renderable buffering and lifecycle propagation, and aligns call sites, tests, release notes, and logging documentation.

Changes

Module-aware console output

Layer / File(s) Summary
Console API and context wiring
src/ModularPipelines/Logging/IConsoleWriter.cs, src/ModularPipelines/Context/*, src/ModularPipelines/PublicAPI.*, docs/docs/how-to/logging.md, RELEASE_NOTES_V4.md, test/ModularPipelines.UnitTests/Context/*
IConsoleWriter moves to ModularPipelines.Logging and defines WriteLine, WriteMarkupLine, and Write. Pipeline and hook contexts expose Console. API baselines and documentation describe the new contract.
Writer and buffered output semantics
src/ModularPipelines/Logging/*, src/ModularPipelines/Console/*, src/ModularPipelines/Engine/SecretObfuscator.cs, test/ModularPipelines.UnitTests/Console/*, test/ModularPipelines.UnitTests/Logging/*
Console output supports plain text, markup, renderables, secret obfuscation, renderable snapshots, and deferred buffer preservation.
Lifecycle propagation and deferred buffers
src/ModularPipelines/Engine/IPipelineSetupExecutor.cs, src/ModularPipelines/Engine/PipelineSetupExecutor.cs, src/ModularPipelines/Engine/Execution/*, test/ModularPipelines.UnitTests/Engine/*
Lifecycle hooks receive an IConsoleWriter. ModuleRunner forwards the writer through lifecycle contexts and preserves ready output when execution is deferred.
Call-site migration and validation
src/ModularPipelines/CommandLine/*, src/ModularPipelines/Engine/DependencyPrinter.cs, src/ModularPipelines.Build/Modules/UnitTests/RunUnitTestModule.cs, src/ModularPipelines/PipelineCli/PipelinePlanPrinter.cs, src/ModularPipelines/PipelineImpl.cs, test/ModularPipelines.UnitTests/CommandLine/*, test/ModularPipelines.UnitTests/Engine/DependencyPrinterTests.cs
Command-line output, dependency printing, and test reporting use WriteLine, WriteMarkupLine, or context.Console. Tests verify method routing and lifecycle writer propagation.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 56346

The PR exposes module-aware console output and changes module lifecycle buffering. Deferred retries may leave output incomplete or show an incorrect completion state, and retained writers may emit late output after completion. The PR should not merge until these lifecycle behaviors are fixed or explicitly accepted by the owner.

Greptile Summary

The PR exposes module-aware console output through pipeline contexts, separates literal and Spectre-markup writes, and adds coordinated buffering and secret masking.

  • Moves IConsoleWriter into the public logging API and updates contexts and call sites.
  • Adds rich-renderable buffering, plain-text report capture, and masking for visible text, links, and control segments.
  • Updates public API baselines, documentation, release notes, and focused tests.

Confidence Score: 3/5

The PR is not yet safe to merge because hyperlink and control-segment masking can emit a registered secret when the configured mask is itself unsafe.

Visible renderable text selects a safe replacement when the configured mask contains a secret, but hyperlink and control metadata use the raw configured mask and are emitted without a later safe masking pass.

Files Needing Attention: src/ModularPipelines/Logging/SecretObfuscatedRenderable.cs and src/ModularPipelines/Engine/SecretObfuscator.cs

Security Review

The unsafe configured-mask fix is incomplete for hyperlink and control-segment metadata. Those branches can reintroduce a registered secret through the configured replacement mask.

Important Files Changed

Filename Overview
src/ModularPipelines/Logging/SecretObfuscatedRenderable.cs Adds comprehensive renderable masking, but link and control payloads bypass safe-mask selection and can reintroduce a registered secret.
src/ModularPipelines/Logging/ConsoleWriter.cs Implements module-aware delegation and masked pipeline fallbacks for literal, markup, and rich output.
src/ModularPipelines/Context/PipelineContext.cs Replaces the unsafe logger cast with an injected console writer, resolving pipeline-level console access.
src/ModularPipelines/Context/ModuleContext.cs Delegates module console output to the module logger with a safe pipeline-writer fallback.
src/ModularPipelines/Logging/ObfuscatedMarkup.cs Preserves markup while masking visible text and delegates rendered metadata masking to the renderable wrapper.
src/ModularPipelines/Console/ModuleOutputBuffer.cs Adds ordered buffering and report capture for rich renderables while preserving newline behavior.
test/ModularPipelines.UnitTests/Console/ConsoleWriterTests.cs Adds broad console and masking regression coverage, but does not combine unsafe masks with link or control metadata.

Code review

Reviewed the diff for PR #4277 against the linked issue (#4231) and the repo's CLAUDE.md.

This is a clean, mechanical API-naming refactor that does exactly what #4231 asked for:

  • IConsoleWriter moved from the root ModularPipelines namespace to ModularPipelines.Logging, and the concrete ConsoleWriter is now internal.
  • LogToConsole(string) split into WriteLine(string) (plain text, escaped) and WriteMarkupLine(string) (Spectre markup) — consistently applied across ModuleLogger<T>, the top-level ConsoleWriter, DependencyPrinter, PipelineCommandHandler, PipelineCommandLineHelp, and the build module.
  • IPipelineContext.Console was added and correctly wired through all three implementers (PipelineContext, ModuleContext, ModuleHookContext), backed by the module-aware/buffered/obfuscated writer rather than the raw singleton — which fixes the actual bug described in the issue (the build module was previously grabbing the unbuffered, unmasked writer via GetService<IConsoleWriter>(); it now uses context.Console).
  • PublicAPI.Shipped.txt / PublicAPI.Unshipped.txt were updated consistently with the namespace move and new member.
  • Docs (logging.md) and RELEASE_NOTES_V4.md were updated, and no stale references to LogToConsole or the old namespace remain outside the "removed" changelog note.
  • Test coverage was added/updated for the new members (ConsoleWriterTests, ContextHierarchyTests, ModuleLoggerTests, SecretObfuscatorTests, PipelineCommandLineTests), including a WriteLine_EscapesMarkup test confirming plain-text output is markup-escaped.

I checked for compile breakage from the interface addition (all IPipelineContext implementations updated; test doubles are Moq-based so they don't need the new member) and found none. I didn't find any bugs or CLAUDE.md violations in the changed code.

No issues found. Checked for bugs and CLAUDE.md compliance.

Code review

Re-reviewed PR #4277 at head ac27960fde2487cbe4d6def7ea3fdcba1203b8db, comparing against the earlier claude[bot] review (CLEAR at 24be0d4b) and the findings other bots raised in between.

Since the last claude[bot] pass:

  • CodeRabbit/Greptile flagged that PipelineContext.Console was doing an invalid cast of Logger to IConsoleWriter. That's now fixed properly — IConsoleWriter is constructor-injected into PipelineContext (src/ModularPipelines/Context/PipelineContext.cs:82, :96) rather than cast from the logger. Good fix.

New issue found in this pass:

  1. Blocking — DependencyPrinter regression: dependency-tree group headers no longer render as markup on local/non-CI runs. src/ModularPipelines/Engine/DependencyPrinter.cs:57 and :65.
    Before this PR, DependencyPrinter routed the fallback writer through _consoleWriter.LogToConsole, which called AnsiConsole.MarkupLine(value) — i.e. it parsed Spectre markup. The refactor split LogToConsole into WriteLine (plain text, AnsiConsole.WriteLine, no markup parsing) and WriteMarkupLine (markup-aware, matches the old behavior) — but the call sites in DependencyPrinter.Print were updated to _consoleWriter.WriteLine instead of _consoleWriter.WriteMarkupLine.
    Concretely: DefaultFormatter.GetStartBlockCommand (used whenever formatter.UsesRawCommands is false, which is the default and applies to local/non-CI runs) returns $"{MarkupFormatter.PlayIcon} {name}", i.e. the literal string "[bold cyan]▶[/] Module Dependencies". Piped through WriteLine, that markup is never parsed, so users will see the raw [bold cyan]▶[/] Module Dependencies text printed instead of a colored play-icon header. This is a real, user-visible regression (with PrintDependencyChains = true, the default), not just a style nit.
    Fix: change both call sites to _consoleWriter.WriteMarkupLine to restore the original rendering.

Non-blocking design suggestion:

  1. src/ModularPipelines/Logging/ConsoleWriter.csWriteLine, WriteMarkupLine, and Write each re-implement the identical ambient-dispatch pattern (if (ModuleLogger.Values.Value is IConsoleWriter moduleConsoleWriter) { moduleConsoleWriter.X(...); return; }). Worth extracting into a small shared helper, e.g. private static bool TryGetModuleConsoleWriter(out IConsoleWriter? writer), and having each method do if (TryGetModuleConsoleWriter(out var w)) { w.X(...); return; }. Three independent copies of the same dispatch logic means a future change to the ambient-lookup behavior (e.g. adding a null check, or a new ambient source) is easy to apply to one method and silently miss the other two, reintroducing subtly inconsistent behavior between plain/markup/renderable output. A single shared helper makes that class of bug structurally impossible.

Everything else — the IConsoleWriter namespace move, IPipelineContext.Console wiring through PipelineContext/ModuleContext/ModuleHookContext, PublicAPI.* updates, docs, and the added test coverage — looks correct and consistent with the stated goal of #4231.

Code review

Nice, focused refactor overall — splitting plain-text vs. markup output (WriteLine/WriteMarkupLine), relocating IConsoleWriter into ModularPipelines.Logging, making the raw implementation internal, and updating the API baselines/tests/docs together is a clean way to land this. I confirmed the LogToConsole migration is complete repo-wide (no leftover references) and the module-scoped obfuscation/escaping tests (ConsoleWriterTests, ModuleLoggerTests) look correct.

Finding: context.Console silently skips secret obfuscation outside an active module — but is now documented as always obfuscating

This PR adds IPipelineContext.Console and documents it, in both the XML doc comment and docs/docs/how-to/logging.md, with an unconditional guarantee:

"Output is buffered with the current module and secrets are obfuscated before rendering."

/// <summary>
/// Gets the module-aware console writer. Output is buffered with the current module
/// and secrets are obfuscated before rendering.
/// </summary>
IConsoleWriter Console { get; }

## Module-aware console output
Use `context.Console` when a module needs plain text or Spectre.Console rendering
instead of structured logging. Its output remains grouped with the module and secrets
are obfuscated before rendering.

That guarantee only holds when a module's AsyncLocal ambient logger (ModuleLogger.Values.Value) is set. PipelineContext.Console is just the raw DI-registered ConsoleWriter singleton, and when no module is ambient, WriteLine/WriteMarkupLine/Write fall straight through to AnsiConsole/System.Console with no call to ISecretObfuscator:

{
public void WriteLine(string value)
{
if (ModuleLogger.Values.Value is IConsoleWriter moduleConsoleWriter)
{
moduleConsoleWriter.WriteLine(value);
return;
}
AnsiConsole.WriteLine(value);
}

This ambient-fallback behavior itself predates this PR (it existed in the old LogToConsole), so it isn't a new bug in that sense. What's new is that this PR turns it into first-class, documented, easily-discoverable API surface — most concretely via IPipelineGlobalHooks.OnPipelineStartAsync/OnPipelineEndAsync, which hand callers an IPipelineContext explicitly before any module has started / after all modules have finished (i.e. guaranteed no ambient module logger):

{
/// <summary>
/// Called before any modules have started.
/// </summary>
/// <param name="context">A pipeline hook context object provided by the pipeline.</param>
/// <returns>A <see cref="Task"/> representing the result of the asynchronous operation.</returns>
Task OnPipelineStartAsync(IPipelineContext context) => Task.CompletedTask;

Concretely: a user implementing IPipelineGlobalHooks.OnPipelineStartAsync(context) and calling context.Console.WriteLine(secretValue) — following the new docs verbatim — will leak the secret to the raw console, contradicting the guarantee this PR itself documents. Previously the raw writer was only reachable via context.GetService<IConsoleWriter>(), which most users wouldn't stumble into; now it's the advertised, "just use context.Console" entry point.

Suggested fix: rather than relying on ambient thread-local detection (which is fragile and easy to bypass from any non-module call site), make obfuscation the default at the ConsoleWriter fallback level too. ISecretObfuscator is already a singleton in the same DI container as IConsoleWriter — inject it into ConsoleWriter and obfuscate in the non-module branches the same way ModuleLogger.WriteLine/WriteMarkupLine already do, instead of only documenting/relying on the module-scoped path. That gives a secure-by-default guarantee that actually matches the new docs, regardless of whether the caller happens to be inside a module.

Code review

Re-reviewed PR #4277 at head 903f806c9d0da13511b08614fe96952836ae3074, comparing against the prior claude[bot] reviews on this PR.

Fixed since the last pass: the invalid (IConsoleWriter) Logger cast in PipelineContext.Console is gone — IConsoleWriter is now constructor-injected directly (src/ModularPipelines/Context/PipelineContext.cs:82, :96), and ModuleContext.Console delegates to _pipelineContext.Console (src/ModularPipelines/Context/ModuleContext.cs:178). Good, targeted fix with a regression test (Console_ReturnsInjectedWriterWithoutResolvingPipelineLogger).

Both previously-flagged BLOCKING issues are still present and unaddressed at this head:

  1. DependencyPrinter regression: dependency-tree group headers no longer render as markup on local/non-CI runs. src/ModularPipelines/Engine/DependencyPrinter.cs:57 and :65 still call _consoleWriter.WriteLine where the old code called _consoleWriter.LogToConsole (which parsed Spectre markup, now equivalent to WriteMarkupLine). DefaultFormatter.GetStartBlockCommand (src/ModularPipelines/Engine/BuildSystemFormatters/DefaultFormatter.cs:15) returns literal markup ("[bold cyan]▶[/] Module Dependencies"), and ConsoleWriter.WriteLine (src/ModularPipelines/Logging/ConsoleWriter.cs:9-18) calls AnsiConsole.WriteLine, which does not parse markup. With PrintDependencyChains = true (the default) on any non-CI build system, users will see the literal [bold cyan]▶[/] Module Dependencies text instead of the colored header. Fix: change both call sites back to _consoleWriter.WriteMarkupLine.

  2. context.Console silently skips secret obfuscation outside an active module, but is documented as always obfuscating. IPipelineContext.Console's XML doc (src/ModularPipelines/Context/IPipelineContext.cs:33-36) and docs/docs/how-to/logging.md unconditionally state "secrets are obfuscated before rendering." That only holds when ModuleLogger.Values.Value (an AsyncLocal) is set, which only happens inside a module's ModuleLoggerScope. PipelineContext.Console is the raw DI-registered ConsoleWriter singleton (src/ModularPipelines/Context/PipelineContext.cs:82), and when no module is ambient — most notably in IPipelineGlobalHooks.OnPipelineStartAsync/OnPipelineEndAsync (src/ModularPipelines/Interfaces/IPipelineGlobalHooks.cs:10-17), which hand callers an IPipelineContext explicitly before any module runs / after all modules finish — WriteLine/WriteMarkupLine/Write fall straight through to AnsiConsole/System.Console with no ISecretObfuscator call (src/ModularPipelines/Logging/ConsoleWriter.cs:9-46). A user following the new docs and calling context.Console.WriteLine(secretValue) from a global hook will leak the secret. Suggested fix (as noted previously): inject ISecretObfuscator into ConsoleWriter and obfuscate in the non-module fallback branches too, so the guarantee holds unconditionally rather than only when a module happens to be ambient.

Non-blocking design suggestion (repeated from prior review, still applicable): ConsoleWriter.WriteLine, WriteMarkupLine, and Write each duplicate the same if (ModuleLogger.Values.Value is IConsoleWriter moduleConsoleWriter) { ...; return; } ambient-dispatch check. Extracting a shared TryGetModuleConsoleWriter helper would prevent a future change to that lookup from being applied inconsistently across the three methods — and would have been the natural place to add the obfuscation fallback from finding 2 above.

Everything else — the IConsoleWriter namespace move, PublicAPI.* updates, and the added test coverage — looks correct and consistent with the stated goal of #4231.

Addressed the blocking review in 1198795: DependencyPrinter now sends local group commands through WriteMarkupLine; ConsoleWriter injects ISecretObfuscator and masks all non-module fallback paths, including renderables; duplicated ambient dispatch was consolidated. Added fallback masking tests for plain/markup/renderable output and a dependency-header routing regression. Validation: core build 0 warnings/errors; ConsoleWriterTests 6/6; DependencyPrinterTests 1/1; diff check clean. @claude please review current head 1198795.

Reran the failed exact-head Claude review job once for 52c38d8; attempt 1 again terminated with is_error:true before posting a verdict. Remaining Pages and CodeQL C# checks are still in progress.

Addressed the BreakdownChart review in 73004e8. BreakdownChart labels and ValueFormatter output are now obfuscated before Spectre measures and lays out tag rows; all chart options and data are preserved in the prepared clone. Regression added. Validation: core Release build succeeded; ConsoleWriterTests 45/45; warning-level analyzers clean. @claude review

Verified the configured-width finding is addressed by ff9f3ad. ModuleLogger now snapshots against the injected effective IAnsiConsole profile and synchronizes its render console to the same width. The 24-column regression passes. Validation: core Release build succeeded; ModuleLoggerTests 14/14; ConsoleWriterTests 45/45; warning-level analyzers clean. @claude review

Claude review check is technically blocked at ff9f3ad after the permitted single rerun (run 33244493233, attempt 2): action returned subtype success with is_error:true and produced no review. All non-Claude checks are green and unresolved review threads are 0. No further automatic retry will be made at this head.

Fixed the Linux CI race in da1879b3c7: ConsoleWriterTests now use unkeyed TUnit [NotInParallel], matching other tests that replace global AnsiConsole.Console. The prior keyed constraint serialized only this class against itself, allowing other Spectre-console tests to overwrite/restore the global console during capture.

Validation:

  • ModularPipelines.UnitTests.csproj Release build: 0 errors (178 existing warnings)
  • ConsoleWriterTests: 45 passed, 0 failed
  • git diff --check: clean
  • Focused format checks only report existing cast-spacing/CA1859 baselines outside the changed line

Claude Code Review failed twice on head 5e60078213ff6458a9b6c28dab30bbf8260d9728 due to an action-level technical failure before review began (is_error:true, num_turns: 1, total_cost_usd: 0, empty modelUsage). No review feedback was produced. Retry allowance exhausted; tracking this as infrastructure failure.

Run: https://github.com/thomhurst/ModularPipelines/actions/runs/33248449823 (attempts 1 and 2)

Ubuntu full-pipeline failure on head 5e60078213 was isolated to unrelated timing test RunHistoryOperationsTimeoutWhenStoreIgnoresCancellation (TimeoutException). The exact test passes locally (1/1, 440 ms). No source overlap with this PR's latest changes; rerunning failed CI job once as transient.
