CI would have run `make _package-archive` against a missing `tools/dist/archive.sh`. Renamed to `tools/packaging/` rather than negating the ignore rule. These are source, not build output, and nothing named `dist` in the tree can be trusted to survive; the new name also says what the scripts do. Also removes src/editors/vscode/test-fixtures/workspace/.editorconfig, which promoted CS0219 to an error across the shared TestFixtures project. Refactor.cs carries an unused local on purpose — it is the fixture the CS0219 quick-fix test refactors — so the fixture build failed, and with it every VS Code chunk at pretest plus the five sidecar tests that build the same workspace. Nothing referenced the file: it set severities no test asserts on, and the quick-fix test gets CS0219 from the compiler regardless.

The two halves of a test id disagreed. `parseFullyQualifiedTestList` strips an adapter's appended unique ID when it builds the tree, so the id is the bare `Ns.Class.Method`. `toTestResult` built `fullyQualifiedName` straight from `TestMethod/@className` + `@name`, and xunit.runner.visualstudio 2.2.0 stamps that attribute with the unique ID — so the report keyed on a name no tree item carries and no outcome could be attributed back (issue #232). A theory made it worse: each row carries a DIFFERENT unique ID, so the rows never collapsed onto the single id they share — which is exactly what `worse()` and OUTCOME_SEVERITY in test-execution.ts already assume when they judge a data-driven test by its worst row. Stripped with the same rule at the one boundary where a TRX name becomes an id. `displayName` keeps the decoration: it is a label, not a key.

The gesture handed control back while the debugger was still coming up, so the whole `debug-tests` chunk failed: no `configurationDone` in the handshake, no breakpoint bound, no stop, and every later test timed out behind the wedged run. The router now settles on ARMED rather than on "configuration was requested": netcoredbg has ANSWERED `configurationDone` — it answers ~80ms later and finishes the attach as it does — and every breakpoint it accepted has bound. A VSTEST host attached under `VSTEST_HOST_DEBUG` has not loaded the test assembly yet, so every breakpoint in the user's own test starts out `verified: false` and binds later by a `breakpoint` event ([DEBUG-FEATURES-BREAKPOINTS-VERIFY]); reporting "attached" before that is issue #233's Debug press that ends in silence. Also fixes Run/Debug Test at the cursor, which invoked the workbench commands `testing.runTests`/`testing.debugTests`. Neither exists, so the lens gesture died with "command not found" and ran nothing; it now presses the extension's own registered profile, the same entry point the Testing view uses. The multi-select expectation asserted breakpoints come back in the order they were armed. VS Code's debug model sorts them by uri then line (`sortAndDeDup`) before sending, and DAP requires the response array to correspond to the request array, so the adapter answers ascending — the expected array is corrected to the order the workbench provably sends, with all three breakpoints still required to bind.

That third directory read as a third project's report. [TEST-COVERAGE] says 'one Cobertura report per test project, each in its own RUN-ID FOLDER one level down', so the helper now filters on the report, which is also the stronger claim: it counts reports findCoberturaFiles can actually load rather than folders that merely exist. The layout is now asserted in full - TRX files, run-id folders, and the attachments folder named for its TRX, which must hold no report one level down. The Debug profile's isDefault assertion could not hold: isDefault is scoped to a KIND, and VS Code writes it back to true on the only profile of a kind so that kind's button has something to press. Asserting false on Debug asserted that the Debug button does nothing. What the play button actually obeys - the Run kind's default - is pinned instead, along with the three kinds being three distinct profiles. Claim 4 of the suite's own header, that coverlet.collector omits the TEST assembly (IncludeTestAssembly is false), had no test. It has one now: every file named across both reports is the library's, neither test source appears, and the library's lines really were measured so the exclusion is not just an empty report.

The tree documents and implements the opposite, naming this exact case: 'deterministic for C# namespaces and dotted F# modules alike (Fs.Xunit.Fixtures.adds two numbers -> Fs.Xunit / Fixtures / adds two numbers)'. That is also what the CLR does - an F# module compiles to a type, so Fs.Debug.Fixtures IS the type Fixtures in namespace Fs.Debug - and it matches the Assembly -> Namespace -> Class -> Test hierarchy the spec and test-tree.ts both describe. The assertions now pin the class row by type name, the namespace row above it, and that the two rejoin to the module the fixture declares. One correction, two chunks: this was the only debug-tests failure and one of six in testexplorer-cancellation. A cancelled dotnet tree on Windows also reports itself now. taskkill was spawned, unref'd and its exit code and stderr discarded, while the POSIX branch reports every signal it fails to deliver - so a kill that never happened looked exactly like one that worked, which is why a surviving testhost writing results for a stopped run left nothing in the log to explain it.

Also formats the debug e2e files thickened in the previous rounds.

Builds real C# and F# console projects. | -| `rundebug-commands` | Both | The run/debug user gestures at the VSIX level: F5 and Ctrl/Cmd+F5 through workbench.action.debug.start / .run, sharplsp.runProgram and sharplsp.debugProgram against built projects, and single-file targets — C# file-based apps, .fsx scripts and the .csx/.fs refusals.

Its own chunk: the suite builds a dedicated F# xUnit fixture whose two long-running tests deliberately sleep, so it is both slow and the most likely place in the matrix to hang — isolating it keeps a hang from taking the rest of the Test Explorer surface with it. | -| `testexplorer-coverage` | Both | The Run-with-Coverage profile against a TWO-test-project solution over one library, each project exercising a DIFFERENT function of it: one Cobertura report per test project, every one parsed and attached, a freshly emptied `.sharplsp-coverage` between runs, partial coverage for the functions nothing called, and the plain Run profile collecting nothing. Its own chunk because every test is a full `dotnet test --collect` round trip.

Its own chunk because it builds and runs a real C#/F# solution before it can look at a lens at all.

Suites are enumerated rather than globbed so a NEW F# suite fails the chunk guard and forces a deliberate placement. | +| `debug` | Both | Getting a program to START, and nothing about what happens once it has: the F5 / no-launch.json resolve contract, launchSettings.json + .run.json profile parsing, the netcoredbg adapter factory, manifest conformance for the debugger, breakpoint, task-definition, command and menu contributions, the [SCRIPT-CONE] launch-target walk with MSBuild output resolution, and the F5 / Ctrl+F5 / sharplsp.runProgram gestures over real projects, C# file-based apps and .fsx scripts. | +| `debug-breakpoints` | Both | Where a live session STOPS, and why. Breakpoints as a user sets them (F9 through the editor, binding and verification, mid-session add/remove/disable, function breakpoints, conditions, hit counts, logpoints); stepping F10/F11/Shift+F11 asserted line by line and frame by frame, Just My Code, run to cursor, stepping off the end of a method and of the program, and the physical/async call stack; and the exception filters — break-on-all catching a handled throw, unhandled-only ignoring one, the info panel and the inner-exception chain. Implements [DEBUG-FEATURES-BREAKPOINTS], [DEBUG-FEATURES-STEPPING], [DEBUG-FEATURES-STACK] and [DEBUG-FEATURES-EXCEPTIONS]. | +| `debug-inspection` | Both | What the debuggee SHOWS while it is paused, plus the two gestures that change a running process. Variables and Watch (locals, arguments, this, statics, collection/array/nullable expansion, hover/watch/REPL evaluation across the T1 and T2 tiers, setVariable changing what the program does next, and [DebuggerDisplay] rendering); F# debugging at full density, never a reduced echo of the C# suites (F9 in an F# editor, stepping through F# functions, discriminated unions/records/tuples/options rendered in F# syntax, task {} logical stacks); and Hot Reload plus attach by pid and by name. Implements [DEBUG-FEATURES-VARIABLES], [DEBUG-FSHARP-UNIONS], [DEBUG-FSHARP-STEPPING], [DEBUG-FSHARP-PDB], [DEBUG-FEATURES-HOT-RELOAD] and the [DEBUG-FEATURES-LAUNCH] attach rows. | +| `debug-tests` | Both | The session and the protocol around it, and the hardest consumer of both. The DAP 1.71.0 handshake and the whole [DEBUG-PROTOCOL-CAPABILITIES] table in both directions, stopAtEntry, args/env/cwd, run-without-debugging, restart, pause and stop, debuggee output routing, and two simultaneous sessions multiplexed by session id — then debugging a TEST through the Test Explorer Debug profile, which re-attaches to successive test hosts inside one session. Grouped because a test-debugging failure is a session-lifecycle failure. Implements [DEBUG-FEATURES-TESTS]. | +| `testexplorer` | Both | The Test Explorer a user READS: discovery, the reactive tree, Windows path handling, TRX/console result parsing, the fully-qualified name reader (adapter decoration stripped, NUnit case names untouched), the testing lens actions, the STATUS half of [TEST-STATUS-LENS] observed as a real CodeLens above a real test method, and the Run-with-Coverage profile against a two-test-project solution over one library — one Cobertura report per test project, every one parsed and attached, a freshly emptied `.sharplsp-coverage` between runs, and the plain Run profile collecting nothing. Implements [TEST-STATUS-LENS] and [TEST-COVERAGE]. | +| `testexplorer-frameworks` | Both | The Test Explorer RUNNING things, over the widest fixture surface in the matrix: the framework matrix (xUnit, NUnit and MSTest in both C# and F#, per-test outcome attribution from TRX, run/debug/coverage profiles, and the pinned 2.2.0 VSTest adapter that decorates the names it reports), and Stop terminating the whole `dotnet test` process TREE across every gesture that starts a run. Kept apart from `testexplorer` because between them they restore and build eight test projects, and because the sleeping-fixture cancellation suite is the likeliest place in the matrix to hang — a hang here must not take the Test Explorer's read surface with it. | +| `workspace` | Both | The IDE surface that is not a language service: activation, configuration, bundled binary/sidecar resolution, client lifecycle and restart, and the cross-cutting command workflows; the Solution Explorer tree with its reactive sort/state signals, tooltips, reveal, full context-menu surface and project-dependency watcher; scaffolding and the NuGet surface down to real .csproj dependency edits; and profiling end to end (dotnet-trace sessions, live counters, memory dumps, .nettrace conversion, profiler webviews) plus FSI and build-output filtering. | +| `realrepo` | Ubuntu only | Cold-loading the three pinned real-world repositories — serilog/serilog, FluentValidation and FsToolkit.ErrorHandling: clone, restore, then drive the LSP over third-party code the fixtures cannot imitate. Linux-only — the Windows gate proves the feature surface, not third-party repo ingestion, and a Windows clone+restore would double the matrix's slowest job for no new signal. | Invariants: +- **A chunk is a GROUP, and the matrix stays readable.** Each platform leg MUST fan out over roughly **6-10** jobs, never one job per feature area. Every job repeats the same multi-minute preamble — `setup-dotnet`, the extension's `node_modules`, three artifact downloads and the VS Code host cache — so a matrix of one-area jobs pays that fixed cost once per area, and at 26 Windows + 29 Ubuntu jobs it spent more runner time on preamble than on tests while producing a check list too long to read. Areas are grouped by what they exercise, so a red job still names a coherent surface. The counter-pressure is wall clock: a chunk projected past **~15 minutes** on either platform MUST be split, and a chunk that HANGS must not be able to take an unrelated surface down with it — which is why `testexplorer-frameworks` (the sleeping-fixture cancellation suite) stays out of `testexplorer`. - **One declaration.** Chunk membership lives in `src/editors/vscode/test-chunks.json` and is read by `tools/vsix/vsix-test-chunks.mjs` (`files ` → `MOCHA_FILES` globs, `matrix` → the CI job matrix, `check` → the completeness guard). It MUST NOT be duplicated into CI YAML. - **Nothing escapes.** `make _lint-vsix` runs `vsix-test-chunks.mjs check`, which fails if any `*.test.ts` suite is claimed by no chunk or by more than one. A new suite is therefore gated on Windows by default; opting out requires an explicit entry under `excluded` with a written reason. - **Selection is by file, not by title.** The inner mocha runner selects suites via the `MOCHA_FILES` glob list. Title-regex selection (`MOCHA_GREP`) is a local debugging aid only — it silently drops tests when a suite is renamed. A glob matching zero compiled suites is a hard error, so a mistyped chunk fails instead of reporting a green run of nothing. diff --git a/src/editors/vscode/src/test/suite/diagnostics.test.ts b/src/editors/vscode/src/test/suite/diagnostics.test.ts index 9da3802d..693fdd00 100644 --- a/src/editors/vscode/src/test/suite/diagnostics.test.ts +++ b/src/editors/vscode/src/test/suite/diagnostics.test.ts @@ -7,6 +7,7 @@ import { openSharpLspPanel, replaceDocumentContent, setupLspTestSuite, + settleForScreenshot, takeScreenshot, teardownLspTestSuite, waitForDiagnostics, @@ -125,7 +126,7 @@ suite('Diagnostics / Problems Panel', () => { } // Open Problems panel so diagnostics are visible in the screenshot. await vscode.commands.executeCommand('workbench.actions.view.problems'); - await new Promise((r) => setTimeout(r, 1000)); + await settleForScreenshot(1000); await openSharpLspPanel(); await takeScreenshot('vscode-diagnostics-page.png'); }); diff --git a/src/editors/vscode/src/test/suite/extension.test.ts b/src/editors/vscode/src/test/suite/extension.test.ts index 160bae74..a0bcdff1 100644 --- a/src/editors/vscode/src/test/suite/extension.test.ts +++ b/src/editors/vscode/src/test/suite/extension.test.ts @@ -6,11 +6,12 @@ import { openCSharpFile, openSharpLspPanel, setupLspTestSuite, + settleForScreenshot, takeScreenshot, teardownLspTestSuite, waitForDocumentSymbols, } from './test-helpers'; -import { ACTIVATION_MS, COMMAND_MS, LSP_RESPONSE_MS } from './test-timeouts'; +import { ACTIVATION_MS, COMMAND_MS, LSP_RESPONSE_MS, SETTLE_MS } from './test-timeouts'; suite('Extension Activation & Configuration', () => { let tmpDir: string; @@ -89,14 +90,24 @@ suite('Extension Activation & Configuration', () => { // ── Configuration ──────────────────────────────────────────── test('sharplsp.lspPath setting is contributed', async function () { - this.timeout(COMMAND_MS); + // The ASSERTIONS here are instant - `config.inspect` reads a contribution + // point out of the extension manifest - and on CI so is the rest: the + // documentation screenshot and its render settle are both no-ops unless + // SHARPLSP_SCREENSHOTS is set, leaving one command round trip. + // + // The budget has to cover the SCREENSHOT run as well, though, and there the + // workbench must paint the filtered Settings list before the capture is worth + // anything.

A type from any of them RESOLVES, the compiler reports nothing, and the add-import lightbulb has no diagnostic to fix. That made exactly five of the ten syntactic positions [SHARPLSP-FEATURES-REFACTORING] requires unexercisable, and the split is exact: the five failing rows name List<> (System.Collections.Generic), EventArgs and Obsolete (System), Select (System.Linq) and File (System.IO); the five passing ones name Stopwatch, Regex, Encoding, CultureInfo and StringBuilder, whose namespaces the SDK does not import globally. The generated obj/.../TestFixtures.GlobalUsings.g.cs lists the seven directives verbatim. The property is declared in the PropertyGroup that already exists to override inherited settings for fixtures. No fixture source depended on the global usings - both `Obsolete` uses are written `System.Obsolete` - and `dotnet build` over the fixture solution stays at 0 errors. Local: 9 of the 11 `lsp` chunk failures go green, including all five add-import rows. 2. src/editors/vscode/src/dap-router.ts The router forwarded EVERY `terminated` and `exited` the adapter sent. DAP permits an adapter to announce the end more than once and netcoredbg does: once when the debuggee exits, again when the client disconnects in reply - and a Test Explorer debug run is an attach, so every one of them ended twice. The router already owned this invariant for the terminations it synthesizes itself, but the flag was never consulted on the child's own repeats, and the synthesized path never recorded that it had announced. Both paths now go through one `endsSessionOnce` guard, and `launch`, `attach` and `onRestart` re-arm it so a respawned session can still announce its own end. CI run 33862379765 shows six debug-tests failures asserting exactly this, each with actual 2 and expected 1. Local: "an F# backtick test whose FQN contains SPACES debugs and breaks in its body" now passes. 3. src/sharplsp/src/diagnostics.rs The single client-publish choke point emitted no trace at all, so what the editor was being told had to be inferred from the editor. It now logs the URI, the count and the diagnostic codes - which is how defect 1 above was separated from a stale-publication theory that turned out to be wrong.

The recovery for that race then escalated to `safeResumePause`: a real DAP `continue` followed by a `pause`, up to three times, on the process the user is debugging. An adapter that runs the user's program to make one of its own reads succeed leaves the program running underneath them - which is the reported shape exactly. The next `stepOver` reaches netcoredbg while the process is live and comes back `Failed command 'next' : 0x80004005`, a bound breakpoint no longer sits on the line it was set on, and every repause injects a `stopped` event nobody asked for. A refused read is now handed to VS Code as the error it is, and the recovery keeps only its PASSIVE half: re-probe `threads`, then read again. A thread parked in native runtime code stays frameless, and `stackFrames: []` is the honest answer for it. Local: "attaching by pid pauses the live process and exposes its state" goes from a 25s mocha timeout to a 3.3s pass. 2. src/editors/vscode/src/dap-fsharp-conditions.ts (new), dap-router.ts A breakpoint `condition` reached netcoredbg exactly as the user typed it, in every language, and netcoredbg's expression evaluator is C#-only. The F# equality `index = 2` is not a comparison to it, so the condition never selected a pass and the breakpoint behaved as an unconditional one - the debuggee stopped on the FIRST hit. The identical C# suite is green only because `index == 2` is already the adapter's dialect. Conditions on F# sources are now rewritten into that dialect - `=` to `==` and `<>` to `!=` - by a literal-aware scan, never a pattern match, so an operator inside a string literal is left alone and `==`/`!=`/`<=`/`>=`/`=>` are not doubled. The rewrite happens before the replayer records the message, so a replayed configuration re-arms the same translated breakpoint. [DEBUG-FEATURES-BREAKPOINTS-CONTRIBUTION] rule 3 calls this asymmetry non-conforming. Local: the F# conditional-breakpoint test goes from `'1' !== '2'` to green, with the C# suite unchanged. 3. src/editors/vscode/src/attach-target.ts `positiveInteger` read a pid with `Number.parseInt`, which stops at the first non-digit, so '12abc' became 12. `isProcessAlive` deliberately treats EPERM as alive - a system-owned pid is a legitimate target - so a mistyped or truncated pid RESOLVED, and the debugger attached to an unrelated system process. That is the hazard the file's own header warns about. A pid spelling is now digits only, checked by round-tripping through the same parser. 4. src/editors/vscode/src/dap-attach.ts The `0x80070057` retry ladder summed to 30.5s and was shared by `attach` and `evaluate`. No response reaches VS Code until the ladder is exhausted, so an attach that hit the very race the retry exists to absorb could not finish inside any caller's ceiling, and it missed [DEBUG-PERFORMANCE] "Attach to running process | <3s" tenfold - DEBUGGING-PLAN 4.3 states the policy as three retries at 500ms. The ladder is now per command and inside that budget, and `EMPTY_STACK_REFETCH_MS` drops from 15s to the same 3s attach budget. Local verification, whole suites: debug-fsharp-stepping + debug-attach + debug-breakpoint-conditions = 15 passing, 0 failing.

A launch carrying `console: "externalTerminal"` therefore failed the gate in the router, was forwarded to netcoredbg verbatim, and no `runInTerminal` reverse request was ever issued - the debuggee quietly took the adapter-hosted row instead of the one the configuration named, which is the silent substitution [DEBUG-FEATURES-LAUNCH-OUTPUT] exists to forbid. Opening the gate alone would not have been enough either: `startTerminalLaunch()` hardcoded `kind: 'integrated'`, so an external launch would still have asked for the wrong kind of terminal. The console attribute now SELECTS the DAP terminal kind through one table, so the routing table has one encoding rather than a literal in a predicate and another in the request it builds. Local: the whole `debug-output-routing` suite is 7 passing, 0 failing - "externalTerminal asks the client for an EXTERNAL terminal" among them, with the integratedTerminal and internalConsole rows and the exclusivity assertion unchanged.

Every refusal leaving the router now carries one, applied at the single emit choke point so there is one rule rather than a special case per command. Local: "setVariable accepts what it can write and refuses what it cannot" goes green. 2. src/editors/vscode/src/attach-target.ts `matchesProcessName` took the file name of each command-line token with `path.basename`, which only knows the HOST's separator. A .NET app launched as `"C:\dotnet.exe" "C:\a b\StepTarget.dll"` therefore matched on Windows and NOT on Linux, where the whole backslash path came back as one "file name" - so attaching by `processName` silently found nothing on one platform and worked on the other. A command line is text from another process, not a host path, and can carry either separator wherever it is read. Local: "the attach resolver decides every configuration shape the schema admits" goes green; the CI failure was Linux-only, which is exactly the shape a host-separator assumption produces. Still open in this chunk, diagnosed with the captured payload rather than fixed: `numbers[999]` comes back as `success: true` with `result: "{System.ArgumentOutOfRangeException}"` — the throw presented as the value. Refusing on that rendering alone would also refuse a watch on a genuine exception variable in a catch block, which is a real regression for users, so it needs a discriminator (an index-bounds check) rather than a rendering test.

That is why exactly the three T2 expressions whose RECEIVER is a string failed while `box.Value`, `box.Describe()` and `numbers.Contains(20)` passed. [DEBUG-FEATURES-VARIABLES] marks T2 "Method calls on locals" as Works for Phase 4, so the gap is the router's to close. The refusal now falls back to answering from the receiver's own rendering, under the governing rule dap-cast.ts already states: emulate only what is EXACTLY derivable from what the adapter rendered. The members served are pure functions of the characters - Length, ToUpper/ToLower, Trim, Contains, StartsWith, EndsWith, IndexOf and their siblings - so the answer is the value the debuggee would compute. Anything else returns undefined and netcoredbg's own refusal reaches the user unchanged. The receiver is found by SCANNING for the last top-level dot, not by matching a pattern: literals are skipped whole and bracket depth is tracked, so `f("a.b").Length` splits outside the literal and `xs[i.j].Length` outside the brackets. `skipLiteral` is exported from dap-emulate rather than copied. 2. src/editors/vscode/src/dap-evaluate.ts An out-of-range indexer is answered SUCCESSFULLY by netcoredbg, with the thrown exception rendered where the value belongs: [dap<-] evaluate ok=true {"result":"{System.ArgumentOutOfRangeException}"} so the Watch panel showed a wrong answer the user would act on, and the request reported success. The discriminator is the careful part. Refusing on that rendering ALONE would also refuse a watch on a genuine exception variable in a catch block, which is a real regression for someone mid-debug. So the rendering is only a cheap pre-filter - it costs no round trip on the overwhelmingly common in-range read - and the refusal itself is decided by an exact bounds check against the receiver's own `Count`/`Length`. A `List<Exception>` indexed in range still answers with its element.

It is the one fold in a file that the DEVELOPER authored — the only place the source itself says "these lines belong together" — and nothing emitted it. A `#region` pairs with a later `#endregion`, which is a span over SIBLINGS rather than a property of one node, so the walk that folds single nodes could never see it. Pairing is done with a stack, so nested regions close innermost-first, and an unclosed `#region` folds nothing: the user is mid-edit and a fold running to the end of the file would collapse the rest of their work. The fold ends ON the `#endregion` line. The directive node runs to the start of the next row, so its end row is one line past the text the user sees. 2. The `using` header never folded either. Each directive is one line and the walk drops every single-line node, so the block of them — exactly what LSP 3.17's `imports` kind exists to collapse — had no range. One fold is now emitted per RUN of adjacent directives, so a blank line or a statement ends the run and a second `using` block below a namespace folds as its own header instead of being swallowed into the first. 3. Every declaration was tagged `FoldingRangeKind.Region`. LSP 3.17 defines three kinds, and `region` names a range the user marked out with `#region` — not every brace pair. Tagging classes and methods `region` meant "collapse the region" collapsed the enclosing class, and left an editor with no way to tell a real region from a class body. A structural fold now carries NO kind, which is what every other server does; comments keep `comment` and the using header gets `imports`. Local: `returns folding ranges for using directives` and `returns folding ranges for region directives` both go green, F# syntax folding is unchanged (4 passing), and all 306 Rust tests pass.

That guard is open for the WHOLE respawn window: `respawn()` signals the old child and only swaps `this.child` inside that child's `exit` handler, so for up to the second before SIGKILL escalation — longer while a paused debuggee lingers — every frame written is silently lost. The frame most likely to be written in that window is `disconnect`. The router forwards it and answers nothing itself, so losing it leaves VS Code with no `disconnect` response and no `terminated`: the session stays live in the workbench until VS Code force-stops it. A session the user cannot close. The window is not rare. Every terminal-hosted launch respawns — `onTerminalResponse` re-spawns the adapter with `--attach <pid>` — and `debug.ts` gives every configuration the real F5 resolver builds `console: 'integratedTerminal'`, so the whole `run-debug-commands` suite goes through it. That suite's teardown, which awaits `stopAnyDebugSession()`, is the one that intermittently times out; on run 33871000054 it failed on Ubuntu and passed on Windows for the same commit. Frames are now held and flushed onto the replacement once it is ready, after `onReady` so the replayed handshake still reaches the new adapter first and the client's own frames follow it in order. Local: run-debug-commands + debug-adapter-e2e (the restart path this changes) + debug-multisession = 9 passing, 1 failing, and the one failure is the pre-existing multi-session case this does not claim to fix — there `vscode.debug.stopDebugging(first)` puts no `disconnect` on the wire at all, so there is no frame to lose.

Only the comment half was implemented: the guard tested `node.kind() == "comment"` and nothing else, so hovering blank space paid the full trip and could pop a tooltip over nothing. Whitespace is read off the tree rather than the text, so the check stays a pure syntax lookup: the smallest node containing a point INSIDE a token is that token, a leaf, while a point BETWEEN tokens resolves to the enclosing construct, which has children. `has_no_symbol_at_position` is the two together, and the handler is renamed to say what it now decides. Local: the blank line in HoverReject.cs is now refused. The suite's other "blank" position is line 5, which is `namespace HoverReject` — column 0 there is the `namespace` keyword, not whitespace — so that assertion still fails; making it pass would mean suppressing hovers on keywords, which is a different rule than the spec states and would put the `var` inferred-type hover at risk. All 306 Rust tests pass, hover.test.js is otherwise green (27 passing).

Tracing a hit-count breakpoint I read "2 stops in, 0 forwarded" and nearly concluded the emulator swallows every stop; the truth, once `fire` was traced, is 2 in and 1 out — it swallows the first and forwards the second, exactly as specified. The two exits now share `emitOutbound`, so the refusal-reason rule applies to a synthesized response as well as a forwarded one, and there is one door out rather than two that had drifted apart. Also widens the DAP payload budget to one named constant.

Seven handlers declared the parameter as `ExplorerNode` and read through it immediately, so every one of them threw `Cannot read properties of undefined` the moment a user found it in the palette; the type was a promise the caller could not keep. Each signature now admits the absence. The three project-file commands share one `projectPathOf` resolver rather than repeating the same guard, which is also what keeps the warning single instead of a cascade, and the four symbol commands say what to do instead of failing silently. `sharplsp.nuget.addFromExplorer` also wore `%cmd.nuget.add%`, so the palette listed "SharpLsp: Add NuGet Package" twice with nothing to tell the two apart — and they differ: one asks which project, the other uses the row the user right-clicked.

The anchor range is now bound once and read from the local. The second fix is the reason the whole `lsp` chunk collapses after the SIGKILL recovery test. `ErrorAction.Shutdown` is TERMINAL in vscode-languageclient: `handleConnectionError` calls `stop()`, the client's state becomes `Stopped`, and `handleConnectionClosed` then returns early forever — so `closed()`, the only thing that ever answers `CloseAction.Restart`, is never reached. Escalating at four errors therefore SPENT the restart budget without ever using it: once the server died, the burst of `ERR_STREAM_DESTROYED` writes on the dead transport tripped the counter and the language client stopped for the life of the window. Every later suite saw `State.Stopped`, and a user's only way back was reloading VS Code.

Visual Studio renders that as a submenu. LSP has no submenus, so the resolver flattens the tree — but it kept the children and DISCARDED the parent, so Ctrl-. offered three fragments beginning with "and" and "into" that say nothing about what they do or to what. Worse, the titles were also the deduplication key. Roslyn offers the same three variants a second time under `Introduce parameter for all occurrences of 'seed * 2'`, and with the parent dropped those collided with the first three and were discarded: half of Roslyn's variants for this refactoring were unreachable from the lightbulb entirely. Each flattened child now carries its ancestry. Measured against the real sidecar on the `RefactorCore` fixture, a caret on `seed * 2` went from three orphan fragments to all six variants, each a sentence about the edit it makes.

A routine shutdown therefore started announcing itself as a death, and the `debug` suite lost `run-debug-commands` to a ten-second wait. The defect underneath is narrower and stays fixed. A REQUEST that cannot reach the adapter got no response at all, so the workbench waited on it forever — and the frame it is most likely to send into that window is `disconnect`, which the router forwards and answers nothing itself, leaving a session in the debug toolbar that the user cannot close. Such a frame is now answered locally. `disconnect` succeeds, because an adapter that is gone IS the disconnected state; anything else fails, which is what a request to a dead process deserves and what lets VS Code surface it rather than hang. Events and responses still drop silently — nothing is waiting on them.

The host filled it with the caller's own declaration range instead, so every navigation from the call hierarchy landed on the calling method's NAME rather than on the call — and the shape had nowhere to put a second site, so a caller that calls the callee twice could only ever be reported once. Both engines knew the answer and threw it away. Roslyn hands back `SymbolCallerInfo.Locations` for incoming and the invocation node itself for outgoing; FCS has the range of every symbol use. The F# side went further and deduplicated CALLERS, so `quadruple`, which calls `double` twice, arrived as one entry carrying no sites at all. The sidecars now send the sites alongside the item, over a call-specific wire record — `prepare` and type hierarchy still answer with a bare item, and the MessagePack encoding is positional, so they could not share one shape. A call that reports no site still lists once at the declaration, so an engine that cannot supply ranges degrades to the old behaviour rather than dropping out of the tree. C# outgoing calls also merge: two invocations of one method were two identical rows that expand to identical children, where LSP wants one row with two ranges. `incomingCalls` / `outgoingCalls` keep their item-returning signatures and become one-line projections of the site-carrying versions, so there is still exactly one implementation of each walk. Measured on the `fsharp` fixture: `double` now reports `quadruple` with two sites, both covering the identifier, and `answer` with one. 30 Rust call/type-hierarchy tests and 67 sidecar hierarchy tests pass.

A selection over an invocation's method name lands inside the identifier, not inside the invocation — so, measured against Roslyn 5.3 on the `InlineMethodTarget` fixture, `Inline 'Doubled(int value)'` is offered for a caret on `Doubled`, and for a selection over `Doubled(seed)`, and withheld for a selection over `Doubled` alone. Double-clicking a word before pressing Ctrl-. is the most ordinary gesture there is, and it took refactorings away. Visual Studio asks Roslyn about the selection AND the caret; so does this now. The selection goes first, so where both answer, the user's own selection is what survives the existing duplicate check. A caret costs nothing extra — there is no second span to ask about. Measured on the same span the suite uses: the lightbulb gains `Inline 'Doubled(int value)'`, its "Inline and keep" variant, and the two Wrapping refactorings, none of which a selection could reach before.

A hung server is exactly when a user reaches for Restart, so `client.restart` now stops with a real budget and starts a fresh server whether or not the old one bowed out in time. The host no longer makes them wait either: `shutdown` is answered on a fast-path thread ahead of the dispatch loop, which LSP 3.17 permits — the answer need not wait for work already in flight. DISTRIBUTION-SPEC rule 6 and the tier-1 bullet in SHARPLSP-SPEC now state both contracts. The remaining changes correct assertions that asserted the wrong thing: - manifest: resolve `%key%` through package.nls.json the way VS Code does, exclude the `<view>.focus`/`.open` commands the HOST registers for every contributed view, and accept a fixture setting pinned to its own default. - symbols: VS Code serialises `DocumentSymbol` without `children`, so every `JSON.stringify(symbols).includes(name)` check walked a tree it could not see. They flatten it now. - hover: line 5 of HoverReject.cs is the `namespace` keyword, not blank. - inlay hints: `var total` earns a Type hint on the call line; the parameter assertions filter to parameter-shaped hints and the Type hint is asserted as the only other kind allowed there. - selection ranges: VS Code merges its own word-part provider into the chain, so the identifier is a level of the chain rather than the innermost one. - refactoring: Encapsulate field resolves as `refactor.rewrite`, which is what the resolver assigns and what the kind's own doc lists. - coverage: run-id folder names are joined through the results directory, and an assembly-root run reports every project because a run is ONE `dotnet test` for the whole selection ([TEST-RUN-TRX]) — one report carries executed lines, the rest are empty. Plain and Debug runs are asserted to leave the directory as the Coverage run left it, not to empty it. - lens status: the C# project declares its tests in TWO files, so lenses are gathered from both. - cancellation: three blocks asserted that unselected long tests had run. They assert the opposite now, against a pre-run baseline. - test debugging ATTACHES to the waiting test host (DEBUGGING-SPEC:664), so the group suite asserts `attach`, never `launch`. - call stack: a console app's managed stack bottoms out at `Main`, so "distinguishable from runtime frames" is the walk reaching Main with no user frame marked subtle. - exceptions: the filter suite reads the recorded request and translates it with the shipped `filterOptionsFrom`, instead of inspecting the local object it sent. An unhandled throw breaks whatever the filters say — there is nothing after it to continue to — and [DEBUG-FEATURES-EXCEPTIONS] now says so. - F# quick fixes: the FCS cold start is paid once in `suiteSetup`, not charged to the first scenario's ceiling.

Those titles are what users read and what callers address, and it cost nine passing assertions in the `lsp` chunk — my regression, and the reason that chunk went from 10 failures to 19. Roslyn writes nested children in two shapes and the difference shows in the first character. `Inline and keep '...'`, `Introduce local constant for '...'`, `Convert to binary` are sentences. `and update call sites directly`, `into extracted method to invoke at call sites`, `into new overload` are continuations of the PARENT's sentence and say nothing alone — which is the orphan-fragment menu the original commit set out to fix. Only continuations are joined now, and with a space, so the result reads as the one sentence Roslyn wrote: `Introduce parameter for '1 + 2' and update call sites directly`. That still keeps the "for all occurrences" group reachable. Its three children are continuations too, so they take their own parent's prefix and no longer collide with the first group's under the duplicate check — which is how half of Roslyn's variants had been disappearing before e5e7111. Measured on the real sidecar: the self-contained titles are back verbatim, both introduce-parameter groups are present, and nothing stutters.

That fixed the real gap — a selection over an invocation's method name could not reach `Inline 'Doubled(int value)'` — but it also pulled in actions for whatever sub-expression the caret happens to land inside. Selecting `1 + 2` began offering `Introduce constant for '1'`, `Introduce local constant for '1'` and six `Introduce parameter for '1'` variants beside the ones for `'1 + 2'`. The user selected an expression; the menu should be about that expression. The caret is now a per-provider FALLBACK, asked only where the provider had nothing to say about the selection. Inline method still appears, because that provider genuinely answers nothing for a selection over the identifier alone, and introduce-constant no longer widens, because it answered. Measured on the fixture: the constant case drops from 26 offered actions to 17, every one removed being about a sub-expression that was not selected, while `Inline 'Double(int value)'` and `Inline and keep 'Double(int value)'` both remain for a selection over `Double(3)`. Warm Ctrl-. holds at ~20 ms, and every provider that answers the selection is now asked once rather than twice.

It only ever learned that line from the `setBreakpoints` RESPONSE, and every breakpoint of a test-host attach is answered before the test assembly is loaded, so the response carries no line and the index keeps the line the user typed. The real bind arrives later as a `breakpoint` event ([DEBUG-FEATURES-BREAKPOINTS-VERIFY]) that nothing fed back, so a stop on the bound line missed the index, was judged unknown, and was forwarded — with the hit count the user typed silently ignored. A hit count of 2 on a two-row [Theory] stopped on row one. `rebind` re-keys the entry to the line the adapter announced and carries the visit count across with it; the router calls it from the `breakpoint` branch, beside `noteBreakpointBind` and in the same child id space `record` uses. Two assertions were asserting the wrong thing: - `assertBoundAtLines` compared bound lines in the order the CALLER armed them. DAP answers `setBreakpoints` in the order of the request, and the request is the workbench's own breakpoint list, which it keeps sorted by line — so an adapter returning [9, 16] for a test that armed 16 then 9 was right and the assertion was wrong. It compares the set now, which is the real claim: every armed line came back bound to itself and none drifted to a neighbour. - test-explorer-cancellation contradicted itself twice. Both tests run the FAST test alone, then demanded every long test's marker on disk — markers only a run of the long tests can write. The recovery test now requires the marker directory to be EMPTY after the fast-only run, which is the real proof the queue rebuilt the filter instead of replaying the cancelled selection, and a fifth interaction runs the whole fixture uncancelled so every original assertion — markers complete, long tests finished, outcomes real — is kept where it is true. The late-Stop test snapshots the marker directory as the finished run left it and requires it unchanged, which is what "changes nothing" means.

One test was asserted the slow way, one asserted the wrong thing: - hover.test.ts `resolveTreeItem uses LSP hover` walked every symbol node of the whole solution — several hundred — and paid two sidecar round trips per node one after another, plus a workbench open/close of the model for every hover on a closed file. That is 36s on Linux and past the 45s sweep budget on Windows, where a hover measures ~80ms rather than ~25ms. Every per-symbol claim is kept; the walk now opens each file once, as the user's own files are, and resolves the tooltips concurrently. One tautology went: `includes(name) || includes('```')` asserted straight after `includes('```')` proved nothing. - debug-test-debugging-e2e `helper reached FROM the test` compared `trace()` output — `Method@line` labels — with the bare method name, so it could never hold. Linux never reached it because Step Over fails first. It now requires the test frame on the stack AT the call it is waiting on, which is the frame a user clicks to see why the helper ran.

The action was in the list under `(int count, string label)` the whole time, so the poll timed out on a title that could not appear. New sidecar test GenerateConstructorFromMembersTests drives the real provider through WorkspaceManager and pins BOTH shapes: a two-field selection offers `Target(int count, string label)`, a caret on the type name offers the parameterless `Target()`. That is where the title came from. - lsp-refactor-spec-gaps inline requeried the ORIGINAL range after the declaration above the call was deleted, so the position translated off the end of the shifted document and the sidecar answered null, not an array. It now requeries the line the call moved to and asserts the action is GONE, an inlined call being nothing left to inline. - tree-config-e2e demanded the fixture's `logging.level` restore to `info`, but the committed fixture pins NOTHING at workspace scope now (a pin there hides every user-scope write behind it), so the value to restore is "removed", not "info". It asserts the override lands at workspace scope, then that the key is unset again and the getter reads the manifest default. - extension-manifest-kit tolerated a workspace pin equal to the default; the fixture pins nothing, so the true claim is the strict one: unset at workspace scope, full stop.

The trace says where it went: 40.375 stopped {threadId: 23024, allThreadsStopped: true} 40.382 stackTrace {threadId: 23024, levels: 20} 40.384 netcoredbg answers it 40.519 next {threadId: 8404} <- a ".NET Long Running Task" thread 40.531 the router finally emits the stackTrace response 40.531 next -> "Failed command 'next' : 0x80004005" netcoredbg is right to refuse: 8404 never stopped. VS Code sent it because `workbench.action.debug.stepOver` steps `viewModel.focusedThread`, and the workbench focuses the stopped thread only once `fetchCallStack()` resolves; before it does, the command falls back to the first thread in the list. Two things were spending that time, and neither could produce an answer: - `recoverChain` evaluated `Task.s_currentActiveTasks` on every stop. That registry only exists once `s_asyncDebuggingEnabled` is set, and only a LAUNCH gets the entry stop that sets it -- an attach never arms it, so the walk could only ever read `null`, at a measured 113ms per stop. `StackDelivery` now remembers whether arming succeeded and skips the walk when it did not. Launch sessions are unchanged: both async-stack suites (`debug-callstack-e2e`, `debug-fsharp-inspection-e2e`) drive `startDebuggee`, which launches, so they still arm and still walk. - `asyncThreadStacks` fetched up to sixteen other threads' FULL stacks one after another. A test host parks a dozen runtime and thread-pool threads; that was 147ms of round trips for a stitch candidate set that is discarded unless exactly one thread qualifies. The probes are issued together now -- same threads, same data, same order, 7ms. The client's `stackTrace` now lands in 20ms and the step reaches the thread that actually stopped. Also: `[dap=>]` logged only headers, so the trace answered "what came back" but not "what did we send" -- which is the whole reason the router keeps one. It carries the outbound body now, under the same payload budget as the other two directions. That is what made the above diagnosable at all.

This branch does not: fe4b146 cut every tier, roughly in half, and never amended the spec. FAST_MS 1s->500ms COMMAND_MS 5s->1s SETTINGS_WRITE_MS 30s->12s LSP_RESPONSE_MS 15s->10s DEBUG_SESSION_MS 45s->20s DEBUG_TEST_MS 50s->25s PROCESS_START_MS 30s->15s DOTNET_CLI_MS 120s->60s LSP_SWEEP_MS 60s->45s SERVER_RESTART_MS 120s->60s ACTIVATION_MS 60s->20s SIDECAR_COLD_MS 90s->45s FIXTURE_BUILD_MS 240s->180s REAL_REPO_MS 600s->480s REAL_REPO_WARMUP_MS 480s->360s WHOLE_RUN_MS 20min->15min Measured on a Windows `debug-tests` shard, MOCHA_FILES over the multisession, groups and debugging suites: eleven failures at the cut ceilings, four at the published ones. The seven that came back are not slow tests -- they finish in 10-12s. `debugging the NAMESPACE row leaves the OTHER namespace alone` 11966ms, `debugging the CLASS row breaks in every test the class contains` 10047ms, `an F# debug run leaves the tree and the spaced ids exactly as they were` 11506ms, `a MULTI-SELECT of two classes debugs both, and nothing else` 12441ms. That last one is why the Windows leg also reported `ONE selection is ONE session; started 2`. Mocha's timeout does not cancel the test body: the timed-out test's `debugRun` was still in flight when teardown ran and the next test's `setup()` installed a fresh `DebugSessionRecorder`, so the leaked `startDebugging` resolved into the new recorder. A cascade, not a second bug. Two comments went back with the values they were rewritten to justify (COMMAND_MS's "one second, and that is the whole budget", SETTINGS_WRITE_MS's). Everything fe4b146 added that is still true is kept -- the "ONE initialization per suite" preamble, and SETTLE_MS, which is new on this branch and is now in the spec's table too so the two agree in both directions. No assertion is touched, no test is skipped, nothing is suppressed.

So `liveOurs` -- documented as "Live session objects of the SharpLsp debug type" -- meant every session ever started. `debug-multisession-e2e.test.ts:309` stops the FIRST of two sessions and polls `liveOurs.map(l => l.id)` until it no longer contains `first.id`. That could never hold, so the test spent DEBUG_SESSION_MS and failed with both ids as its last observed value -- which is exactly what CI reported. It also made the assertion after it vacuous: `liveOurs.some(l => l.id === second.id)`, "ending the first session must not take the second down with it", was true of an array nothing is ever removed from. Both are real claims now. The recorder drops a session when the workbench says it terminated.

A debug run was on that queue too. Under `VSTEST_HOST_DEBUG` its `dotnet test` does not exit until the user has finished debugging, so the queue was held for as long as a breakpoint was held -- and for that whole time the Test Explorer could not discover anything and no other run could start. Pressing Refresh in the Testing view while paused simply hung. Measured, from a Windows trace of `debug-test-fsharp-e2e`: 13:19:46.077 Loading solution into state: DebugTestTargetFsSln.slnx 13:19:46.914 Symbols loaded ... 39 seconds of nothing ... 13:20:26.055 Test debug: the run ended with 1 result(s) 13:20:28.738 Test discovery: 1 item(s) from 1 target(s) The sweep did not fail and was not slow. It waited for the debuggee, then took 2.7 seconds. The run now holds the queue for the BUILD and releases it once a host is waiting and its attach has settled -- strictly after the race the queue exists to prevent, since a host that is waiting has already been built. A run that dies before any host waits releases it the same way, through the same race. Two tests come back with it, both of which read the tree after their last breakpoint stop and had been waiting on a debuggee that was never going to exit: `an F# [<Theory>] breaks once per row, each with its own arguments` (22.7s) and `debugging the ASSEMBLY root debugs every namespace under it, in one session` (14.6s). Both need the restored DEBUG_TEST_MS as well; neither fits the ceiling this branch had cut it to. Spec: [TEST-RUN-TRX], [DEBUG-FEATURES-TESTS].

The test also required that the second hit be the second `[InlineData]` in DECLARATION order, which xUnit does not guarantee. `DefaultTestCaseOrderer` sorts a class's cases by a hash of the test case's unique id, so the order is stable per method and arbitrary between methods. This very fixture proves it. The C# `Adds_Rows` and the F# `adds rows` declare the same two rows in the same order, run under the same runner, in the same push -- and the C# theory executes (10, 20, 30) first while the F# one executes (1, 2, 3) first. The C# `[Theory] stops ONCE PER ROW` test beside this one already knows: it sorts before comparing. From the wire, the emulation is exactly right: 31.367 stopped "breakpoint" first execution 31.372 [router] continue ok=true swallowed, count 1 of 2 31.382 stopped "breakpoint" second execution 31.386 [=>] stopped ... hitBreakpointIds:[1000001] the ONE stop the user sees Nothing about the product changes here, and nothing is weakened. "Only one stop happened" is what proves a hit was skipped, and the test already asserts it at the end. What replaces the declaration-order assertion claims MORE than it did: the three locals must form ONE COHERENT ROW of the theory, so a frame answering `left` from one row and `expected` from the other -- a debugger showing a state that never existed -- now fails where it used to pass.

The earlier fix took the client's `stackTrace` from 149ms to 20ms, which is enough to win that race on one platform and not the other. 20ms of nothing is still 20ms. The workbench focuses the stopped thread only once `fetchCallStack()` resolves. Until it does there is no focused thread, and `workbench.action.debug.stepOver` falls back to `getAllThreads()[0]` — a thread that never stopped, which netcoredbg then refuses. So the response has to be immediate, not merely fast. It can be. Without the async-task registry — which only a LAUNCH arms, so never in a test-host attach — `recoverChain` has nothing to read, and a tail CONTINUES a chain, so with no chain recovered there is nothing to continue either. The rebuild's whole output is the frames the adapter already returned, bought with a full re-fetch and a queue hop. An unarmed session now answers from those frames directly, in the same tick netcoredbg answered in. Two changes, both statements about what the reconstruction can produce rather than about speed: - `deliver` rebuilds only when the registry is armed AND the response carries state-machine frames. Unarmed, the enriched frames ARE the answer. - `assemble` stitches a tail only onto a chain that was actually recovered and cut. Splicing another thread's frames onto a stack with no chain would invent a caller the debuggee never had — wrong regardless of what it costs. Launch sessions are untouched: both async-stack suites (`debug-callstack-e2e`, `debug-fsharp-inspection-e2e`) drive `startDebuggee`, which launches, arms at the entry stop, and still walks the heap exactly as before.

That is wrong, and `stitchedTail`'s own documentation says why: "a stop can freeze the debuggee while an awaiter is mid-suspension: its box exists but its continuation is not yet hooked, and the awaiting methods are still PHYSICAL frames on the thread that is suspending them". An empty chain with a tail on another thread is not the degenerate case — it is the case the stitch was written for. It cost four green jobs. `debug-breakpoints` and `debug-inspection` went red on both platforms, and locally: an F# task {} chain reports the logical await stack [DEBUG-FEATURES-STACK-ASYNC] applies to F# `task {}` verbatim ... The awaiting frame must be injected. Frames: FsStepTarget.Program.leafTask() One frame, because the awaiting frame lives on the suspending thread and only the stitch goes and gets it. Reverted to the line that was green, verbatim. The other half of 0b27c29 stands and is untouched: an UNARMED session still answers `stackTrace` straight from the adapter's frames, which is what the Linux stepping race needs, and no armed session reaches that branch.

Making the client's `stackTrace` synchronous for an attach did not win the Linux race: `VS Code / debug-tests` still reports the 'workbench.action.debug.stepOver' gesture must not reject: Failed command 'next' : 0x80004005 while the same job passes on Windows. The wire says why, and it is not timing at heart. The stop is on thread 23024; VS Code sends `next {"threadId": 8404}` -- a ".NET Long Running Task" that never stopped. `workbench.action.debug. stepOver` steps `viewModel.focusedThread`, and the workbench focuses the stopped thread only once `fetchCallStack()` has resolved; before that there is no focused thread and the command falls back to `getAllThreads()[0]`. In a test host that is a runtime or thread-pool thread. netcoredbg keeps ONE current thread and refuses every other, so the user's F10 surfaces as a raw HRESULT. Shortening the window made Windows win it. It cannot make the window zero: the workbench's focus is its own asynchronous step, and any user quick enough on F10 loses the same way against any adapter that only steps its current thread. So the refusal is rescued instead. The router already remembers what the adapter announced; a step that comes back refused with `0x80004005` or `0x80131309` is re-issued against that thread and the retry answers the client's original sequence number. Rescued, never pre-empted. A step the adapter performs is forwarded untouched, so a user who deliberately selected a different stopped thread is unaffected -- which a blanket retarget could not promise. E_FAIL means no step happened, so re-issuing cannot double-step. It is the same shape as the `0x80070057` attach retry that already lives next door. Implements [DEBUG-ADAPTER-GAPS] for the [DEBUG-FEATURES-STEPPING] rows.
