TranscriptScrollPin is a pure value type (starts pinned; update(distanceFromBottom:) unpins past Layout.autoscrollPinThreshold, inclusive at the boundary; re-pins on return to 0; stays pinned on negative/overscroll distance). TranscriptView wires it via a PreferenceKey carrying the bottom anchor's frame in a named coordinate space attached to the ScrollView, feeding (anchorMinY - viewport height) into pin.update(distanceFromBottom:); scrollIfPinned now guards on pin.isPinned instead of the previously never-mutated pinnedToBottom constant.

CollectionLoadState.failed now carries the server's own message, plus showsError and showsPlaceholder(itemCount:) helpers so views stop hand-rolling `state != .loaded` skeleton checks. A failed load is deliberately excluded from showsPlaceholder — the bug was a failure rendering identically to an endless loading skeleton. New CollectionErrorState view (icon + verbatim server message + Retry), mirroring StartupFailureView's existing "this failed, here is why, retry" shape at inline/per-collection scale. Wired into every consumer: task/run sections in ActivityView, the conversations list and checkpoints in SessionsView, providers/models tabs in SettingsView, and the provider and model lists in ModelSettingsView (which also gained a per-collection failed(message) instead of a bare failure marker). ProjectSession's eight `= .failed` assignments now carry error.localizedDescription; the existing statusMessage toast write is unchanged, so ProjectSessionActivityTests still pass unmodified in intent.

Two angles distinct from the behavioral tests already covering CollectionLoadState's own logic and ProjectSession's per-collection messages: - Per-file wiring: the existing module-wide reachability check is satisfied the moment any one view wires CollectionErrorState in, so a revert that drops the wiring from five of the six U2 consumers while leaving it in the sixth would pass silently. A new test pins ActivityView, SessionsView, SettingsView, and ModelSettingsView individually, each for both `CollectionErrorState(` and `.showsError`. - A different integration point: ModelSettingsModel holds its own CollectionLoadState via client.modelSettings(), never exercised by the ProjectSession-driven tests (which cover client.models()/providers()/ conversations()). Catches a revert of ModelSettingsView.swift's `.failed(error.localizedDescription)` back to a bare `.failed`. Kept the new ModelSettingsModel test inside the existing `.serialized` ProjectSessionLoadStateTests suite rather than a suite of its own: both share LoadStateStubProtocol's single global handler, and a separate suite running concurrently with this one raced it (observed one flaky failure before the merge; stable across 3 repeated full-suite runs after).

Implementation for tests added in 784bb195. RunSession.cancel/approve/deny/answer now await the server call inside a do/catch, matching the pattern steer() already used correctly: a HarnessError sets connectionError to its message, a transport error sets it to localizedDescription. A failed cancel resets cancelRequested to false so the operator's next press retries the cooperative request rather than escalating to a local force-kill. answer(_:) validates completeness against pendingQuestions via the new AskUserAnswers.isComplete and clears pendingQuestions only after answerInput returns successfully -- a rejected answer leaves the prompt on screen. New AskUserAnswers.isComplete(prompt:answers:) replaces `answers.count < prompt.questions.count`, which counted a field cleared back to "" (or left whitespace-only) as answered. Shared by RunSession's guard and AskUserView's Send-button `disabled` predicate in ChatView.swift so both read the same rule. Only whitespace reformatting (swift-format) applied to the red-committed RunControlAckTests.swift; no assertions changed.

Confirmed against the pre-fix source at 8f2e4121: RunSession.swift there still contains `try? await client.cancel/approve/deny/answerInput`, and ChatView.swift there still contains `answers.count < prompt.questions.count`. Two angles distinct from the behavioral tests already covering the runtime behavior: - RunControlAckTests exercises each of cancel/approve/deny/answer through a live stub, proving the *behavior* is fixed, but a partial revert of one call site back to `try?` would only be caught if that specific method's test happened to still be run against the reverted code -- this pins the absence of the bug shape across the whole file in one assertion. - AskUserAnswersTests pins the predicate's own logic in isolation but does not prove AskUserView's Send button still calls it; a revert that reintroduces `answers.count < prompt.questions.count` while leaving AskUserAnswers.swift untouched (and its own tests passing) would slip through that suite alone.

ProjectSession.swift: adds `RewindRefusal` (point + server message) and `rewindRefusal` observable state, cleared at the start of every `rewind` call (including its own retry) so a stale refusal from a prior point can never bleed into a new one. `rewind`'s catch now branches on `HarnessError.code == "rewind_refused"` (KTD-6 -- the code is the stable contract, not the HTTP status it happens to arrive with) and records the refusal instead of collapsing it into `statusMessage` prose; every other `HarnessError` still lands in `statusMessage` as before. `dismissRewindRefusal()` clears a refusal with no server call, for the confirmation's Cancel path. SessionsView.swift: `CheckpointsView` retires the stale #951 finding-9 NOTE and presents a second `DestructiveConfirmation` (U5's shared component) keyed off `project.rewindRefusal` -- worded distinctly from the ordinary restore alert (names the file-changed-outside-the-harness fact, quotes the server's message, confirm label "Restore Anyway") and calls `rewind(to:refusal.point, force: true)` only from that branch. Declining calls `dismissRewindRefusal()`; nothing is ever auto-retried with force. Also fixes a reentrant-lock deadlock in the new test file's stub: a handler that calls `RewindStub.bodies(matching:)` to count prior attempts was being invoked while `startLoading()` still held the same non-reentrant `NSLock`. Test runner output (all passing): ✔ Test "a rewind_refused refusal is captured structurally, matched on HarnessError.code -- core regression" passed ✔ Test "a generic failure sets statusMessage and offers no force path" passed ✔ Test "confirming the refusal sends force:true, and the refusal clears once the forced call succeeds" passed ✔ Test "a second refusal on the forced call sets rewindRefusal again rather than looping or clearing silently" passed ✔ Test "a successful rewind reports the restore counts with no refusal -- existing behaviour, pinned" passed ✔ Test "SessionsView wires force: true only inside the refusal-confirmation branch, and the stale NOTE is gone" passed ✔ Test run with 232 tests in 48 suites passed after 24.561 seconds. (226 at the U5 baseline; +6 here.) swift build and swift format lint --strict --recursive Sources Tests both clean. Behavioral tests covered: R7 (rewind_refused surfaced structurally, distinct force confirmation, never auto-retried).

PromptHistory (new, Sources/GoCodeUI/PromptHistory.swift) is a pure value type: entries + an optional cursor + a stashed pre-recall draft. recallPrevious(currentDraft:) starts navigation only from an empty draft (stashing it), walks backwards with no wraparound past the oldest entry, and -- once already navigating -- declines instead of overwriting an edit that has diverged from the entry last recalled (KTD-7's caret-awareness approximation, since TextSelection/caret binding is a macOS 15 API and this package floors at .macOS(.v14)). recallNext() walks forward and restores the exact stashed draft past the newest entry, then declines. record(_:) always resets navigation. RunSession replaces `promptHistory: [String]` with a `PromptHistory`, records on submit(), and exposes recallPreviousPrompt() / recallNextPrompt() (Bool return: whether something was recalled) plus noteManualDraftEdit() so a manual edit after a recall clears navigation rather than letting the next arrow press silently replace it. ChatView's Composer wires .onKeyPress(.upArrow/.downArrow) on the draft field, returning .handled only when the session actually recalled something so the field's own multi-line navigation still works otherwise, and calls noteManualDraftEdit() from the existing onChange(of: run.draft) for any change the recall handlers did not themselves cause -- closing the #927/#998 gap where recallPreviousPrompt had no production call site. Test runner output (all passing): Test run with 10 tests in 1 suite passed after 0.002 seconds. (PromptHistory cursor navigation) Full suite: 245 tests in 49 suites passed (up from the 235-test baseline). swift build clean. swift format lint --strict --recursive Sources Tests clean. Behavioral tests covered: all 9 PromptHistoryTests scenarios from the plan's U7 section plus the mandated reachability check.

SessionsView.swift: conversation rows are now a Button wrapping ConversationRow (.buttonStyle(.plain) keeps the look), replacing .onTapGesture, with an .accessibilityLabel naming title, message count, and pinned state. The context menu is unchanged. - SettingsView.swift: ModelsTab rows are likewise a Button with an .accessibilityLabel naming the model id, provider, and selection state, replacing .onTapGesture { project.selectedModel = model.id }. - ModelSettingsView.swift: - ModelSettingsModel.load(clearingStatus: Bool = true) replaces load(). The .task initial load keeps the default (clears any stale status); fetch/setExposed/setAllVisible/saveProvider/delete now call load(clearingStatus: false) on both success and failure so the message they just set survives the reload they trigger instead of being erased by it. - The exposure Toggle gains .accessibilityLabel("Show \(modelID) in the picker") alongside its existing .labelsHidden() + .help(...). - Provider "Remove" now calls a new confirmRemove(_:) that presents a DestructiveConfirmation (from U5) stating that removal drops the provider's exposed models, instead of calling model.delete immediately from the button action.

F1b: a success answer must only clear pendingQuestions when it is still the very prompt that was answered (a newer prompt assigned mid-flight must survive). F2: a second cancel() press while the first cooperative cancel is still in flight must not escalate to a local force-stop. F3: a cancel Task that resolves after reset() must not write a stale connectionError for the abandoned run. F4: deleteConversation must refuse up front for its own busy conversation -- the DELETE must never reach the server. F5: fork/undo must re-check busyness after their server call, before applying rebind/reload, so a run started mid-flight is not clobbered. F6: openConversation must refuse while a run is active. F7: PromptHistory.recallPrevious must decline (nil) rather than repeat a same-value no-op at the oldest entry -- a same-value draft reassignment never fires SwiftUI's onChange, which left the composer's isRecallingHistory flag stuck and misattributed the next real edit. F8: the transcript's scroll pin must ignore geometry updates while its own scrollTo animation is in flight (and before a real viewport height is known), or it self-unpins from the very scroll it triggered. Test runner output (expected: all new tests failing meaningfully, zero regressions in the 262-test baseline): ✘ Suite "PromptHistory cursor navigation" failed with 1 issue. ✘ Suite "Transcript feature reachability" failed with 5 issues. ✘ Suite "ProjectSession lifecycle guard" failed with 6 issues. ✘ Suite "RunSession control acknowledgements" failed with 4 issues. Test run with 273 tests in 52 suites failed after 4.784 seconds with 16 issues. (16 issues == 4 RunControlAckTests + 6 ProjectSessionLifecycleGuardTests + 1 PromptHistoryTests + 5 TranscriptFeatureReachabilityTests -- exactly and only the 11 new tests; every one of the 262 baseline tests still passes.) Sample failures, each meaningful (not an import/compile error): - PromptHistoryTests.swift:134: recallPrevious(currentDraft: "a") returned "a" instead of declining with nil. - RunControlAckTests.swift:351: session.transcript.runState became .cancelled during an in-flight cooperative cancel. - RunControlAckTests.swift:407: a stale connectionError ("cancel rejected") was written after reset(). - RunControlAckTests.swift:489/576: a second answer() sent a duplicate POST, and pendingQuestions was cleared to nil instead of surviving as call_2. - ProjectSessionLifecycleGuardTests.swift:268/296-298/380/426: the DELETE/messages/undo-reload calls reached the server, and fork/openConversation applied their result, while a run was busy. - TranscriptFeatureReachabilityTests.swift:104-105/143-150: ChatView.swift does not yet contain the answerInFlight-gated Send button or the isAutoScrolling guard (these two are source-scan tests, matching this file's existing pattern for view-layer state not otherwise assertable through a headless test on this stack). These tests will pass after the implementation in the next commit. --- .../ProjectSessionLifecycleGuardTests.swift | 189 ++++++++++- .../GoCodeUITests/PromptHistoryTests.swift | 24 ++ .../GoCodeUITests/RunControlAckTests.swift | 304 ++++++++++++++++++ .../TranscriptFeatureReachabilityTests.swift | 48 +++ 4 files changed, 557 insertions(+), 8 deletions(-) diff --git a/macapp/Tests/GoCodeUITests/ProjectSessionLifecycleGuardTests.swift b/macapp/Tests/GoCodeUITests/ProjectSessionLifecycleGuardTests.swift index 7087a0c1..d25f5269 100644 --- a/macapp/Tests/GoCodeUITests/ProjectSessionLifecycleGuardTests.swift +++ b/macapp/Tests/GoCodeUITests/ProjectSessionLifecycleGuardTests.swift @@ -235,14 +235,15 @@ struct ProjectSessionLifecycleGuardTests { project.run?.reset() } - /// `deleteConversation`'s own call to `newConversation()` (`:349`) only - /// fires when the deleted conversation is the one currently open.

RunSession.swift: - answer() gains an answerInFlight guard (cleared via defer on every exit path) so a second call while the first is in flight is a no-op; a success only clears pendingQuestions when it is still the prompt this call answered (compared by callID), so a newer question assigned mid-flight survives. - cancel() replaces the cancelRequested bool (set true synchronously, before the request resolved) with an explicit CancelState (.idle/ .requesting/.requested) state machine, so a second press only escalates once the server has actually acknowledged the first cooperative cancel. - cancel()'s and answer()'s Tasks capture their runID and guard every connectionError/pendingQuestions/cancelState write on currentRunID still matching it, so a Task that resolves after reset() cannot write stale state into a new run/conversation. reset() now also resets cancelState and answerInFlight directly, since the guard above only stops a stale Task from overwriting NEW state -- it does not clear old state itself. ProjectSession.swift: - deleteConversation refuses up front (distinct message) when the target conversation is the current, busy one -- the DELETE no longer reaches the server before the local refusal, unlike before when the delete happened and only the internal newConversation() call refused. - fork/undo re-check busyness after their server call, before applying rebind/reload, so a run started on the same conversation while the request was in flight is not clobbered. - openConversation gains the same refuseIfBusy guard as newConversation/ fork/undo. PromptHistory.swift: - recallPrevious declines (nil) instead of repeating a same-value no-op when already at the oldest entry and the draft already shows it. A same-value reassignment never fires SwiftUI's onChange, which left the composer's isRecallingHistory flag stuck and misattributed the next real edit. ChatView.swift / DesignSystem/Motion.swift: - TranscriptView gains an isAutoScrolling flag, set for the duration of scrollIfPinned's scrollTo animation (Motion.autoscrollDuration, replacing the prior 0.12 literal). pin.update is skipped while that flag is set or before scrollViewportHeight reports a real value, so the pin can no longer self-unpin from its own programmatic scroll. TranscriptScrollPin itself is untouched -- it stays a pure decision. - AskUserView takes answerInFlight and disables Send while it is true. Test runner output (expected: all passing): ✔ Suite "PromptHistory cursor navigation" passed ✔ Suite "Transcript feature reachability" passed ✔ Suite "ProjectSession lifecycle guard" passed ✔ Suite "RunSession control acknowledgements" passed Test run with 273 tests in 52 suites passed after 11.334 seconds. swift format lint --strict --recursive Sources Tests: clean.

The defect is purely that `RunSession` wraps them in `try?`. Fix: `await` the call inside the existing `Task`, catch `HarnessError`, and publish the message on a `RunSession`-owned observable. Reuse the existing `connectionError` slot — it is already rendered by `InlineRunStatus` (`ChatView.swift:716`) and by definition means "the last thing this session asked the server for did not work". *Rejected:* a new per-control error enum and a new banner — one more surface for the same information. + +**KTD-2 — `CollectionLoadState.failed` gains an associated message.** +`statusMessage` is a single last-writer-wins slot shared by 8 collections (`ProjectSession.swift:205-300`), so an inline error next to a failed list cannot truthfully name *that* list's failure by reading it. Change `case failed` → `case failed(String)` and add `showsError` / `showsPlaceholder(itemCount:)` helpers alongside the existing `showsEmptyState(itemCount:)` so views stop hand-rolling `state != .loaded && items.isEmpty`. This is the widest diff in the plan (six files) and is why U2 runs early — a fail-fast placement. *Rejected:* a parallel `failureMessage` dictionary keyed by collection — two things to keep in sync, and nothing stops them diverging. + +**KTD-3 — Retry is a closure supplied by the view, not a registry.** +Each load state already pairs one-to-one with a `refresh*` method. `CollectionErrorState(message:retry:)` takes `{ Task { await project.refreshConversations() } }`. No mapping table, no protocol. + +**KTD-4 — One shared destructive-confirmation presentation, built once in U5 and reused by U6 and U8.** +The app already uses `.alert` with a `Binding` derived from an optional item (`SessionsView.swift:184-200`) — that shape is the pattern, extracted into one `DestructiveConfirmation` component so delete, undo, rewind, force-rewind, and provider-remove read identically and cannot drift apart in wording severity. + +**KTD-5 — Delete/undo previews are derived client-side. There is no server dry-run.** +Verified: `POST /v1/conversations/{id}/undo` mutates and *then* reports `removed_from_step` / `remaining_messages` (`internal/server/http_conversations.go:588-616`); `handleDeleteConversation` has no preview mode (`:831`). So a pre-action preview must be composed from data the app already holds: `ConversationInfo.displayTitle` + `messageCount` for delete, and the last `.userPrompt` item in `run.transcript.items` for undo. Server changes stay out of scope. + +**KTD-6 — Match `rewind_refused` on `HarnessError.code`, not the HTTP status.** +The server passes a computed status to `writeError(w, code, "rewind_refused", …)` (`internal/server/http_conversations.go:370`), so the code string is the stable part of the contract. `ProjectSession.rewind` returns a typed outcome and records `rewindRefusal` (point id + server message) instead of stringifying into `statusMessage`. + +**KTD-7 — Prompt-history cursor is a pure value type; "cursor-aware" is approximated by draft state, not caret position.** +`PromptHistory` (entries + cursor index + a stashed pre-recall draft) is a plain struct, unit-testable without a view. The literal reading of #998 — "cursor-aware", i.e. only recall when the text caret is on the first/last line — is **not implementable on this package's platform floor**: `Package.swift` pins `.macOS(.v14)`, and a SwiftUI `TextField`/`TextEditor` selection binding (`TextSelection`) is a macOS 15 API. Approximation: Up recalls only when the draft is empty or unchanged from the current recall; otherwise it declines and lets the field handle the key normally. See Assumptions and the deviation note. + +**KTD-8 — Autoscroll pinning is a pure model fed by geometry, not a view-local `Bool`.** +`TranscriptScrollPin` (threshold + `mutating func update(distanceFromBottom:)` + `isPinned`) is unit-testable; the view supplies the distance via a `GeometryReader` on the existing bottom anchor read in a named coordinate space. `.onScrollGeometryChange` / `.onScrollPhaseChange` are macOS 15 APIs and are unavailable here; `scrollPosition(id:)` reports the leading visible item, which is the wrong end of the scroll view for this decision. + +**KTD-9 — Guards live in `ProjectSession`, not at each call site.** +`newConversation` has four callers (`SessionsView.swift:17`, `ChatView.swift:901`, `ConversationChrome.swift:32`, and `ProjectSession.deleteConversation` itself at `:349`); `fork` and `undo` each have three (`ChatView.swift:343/351`, `ConversationChrome.swift:34/35`, `SettingsView.swift:197/198`).

The epic's logical dependency chain (U3 → U4 → U5 → U6) is preserved, and U2 — the widest diff — is front-loaded so a bad shape fails fast.

In `TranscriptView`, wrap the existing bottom anchor (`ChatView.swift:103`) in a `GeometryReader` and read its frame in a `.coordinateSpace(name:)` attached to the `ScrollView`; feed `scrollViewHeight - anchorMinY` into `pin.update(distanceFromBottom:)`. +3. `scrollIfPinned` (`:127`) now guards on `pin.isPinned`. A programmatic `scrollTo` re-enters the geometry callback with distance ≈ 0, which re-pins — correct and self-consistent. +4. Keep the existing `withAnimation` and both `onChange` triggers unchanged. + +**Patterns to follow.** `LoadingPlaceholder` (a small view whose behaviour is driven by injected values); token-first measurements per `DesignTokenTests`; `MarkdownBlock` as the precedent for "the logic is a value type, the view just renders it". + +**Test scenarios** (`macapp/Tests/GoCodeUITests/TranscriptScrollPinTests.swift`): +- *Happy:* a new pin is pinned; `update(distanceFromBottom: 0)` keeps it pinned; `scrollIfPinned` therefore fires. +- *Core regression:* `update(distanceFromBottom: threshold + 1)` → `isPinned == false`.

Mirrors `StartupFailureView` (`AppShell.swift:245-268`), which is already the app's "this failed, here is the reason, try again" shape. +3. `ProjectSession` failure branches become `.failed(error.localizedDescription)`. Keep the existing `statusMessage` write — it is the cross-cutting toast and is asserted by `ProjectSessionActivityTests`; U2 must not regress those two tests. +4.

Replace each `try? await client.…` with an awaited call in a do/catch that sets `connectionError` from `HarnessError.message` (or `localizedDescription` for transport errors) — the same catch shape `steer()` already uses correctly at `RunSession.swift:158-166`. `steer` is the in-repo reference implementation; the other four are the outliers. +2. `answer(_:)`: validate first (step 3), then `await client.answerInput`, and clear `pendingQuestions` **only after** it returns. On failure keep the prompt on screen and set `connectionError`. +3. `AskUserAnswers.isComplete(prompt:answers:)` — every question id present with a non-blank trimmed value. Used by both `RunSession.answer`'s guard (root cause: covers any future caller) and `AskUserView`'s `disabled` (so the button reflects the same rule).

Fails today because `load()` nils it. + - *Error:* fetch fails → `status` contains the provider's verbatim reason **and** survives the subsequent `load()`. + - *Happy:* the initial `.task` load with no prior status → `status == nil`, `loadState == .loaded` (the clearing path is still correct where it is wanted). + - *Edge:* `setExposed` failing → its error message survives the reload. + - *Edge:* `load(clearingStatus: true)` after a stale error → status cleared, so an error cannot become permanent. +- `AccessibilityReachabilityTests.swift` (source-scan, the pattern from `TranscriptFeatureReachabilityTests`): + - `SessionsView.swift` no longer contains `.onTapGesture` on a conversation row, and the row carries an `.accessibilityLabel`. + - `SettingsView.swift` no longer contains `.onTapGesture { project.selectedModel = model.id }`. + - `ModelSettingsView.swift` contains `.accessibilityLabel(` within the exposure-toggle region and no bare immediate `Task { await model.delete(` outside a confirmation. + - Guard against regression breadth: assert `Sources/GoCodeUI` contains no `.onTapGesture` on any row that also carries `.contentShape(.rect)` — the exact shape of this defect, so a third instance cannot be introduced. + +**Execution note.** Strict TDD: feedback tests red first; the reachability assertions are written red against current source and go green with the view edits. + +**Verification.** `swift build`, `swift test`, `swift format lint --strict --recursive Sources Tests`, plus a VoiceOver + keyboard-only smoke on the Sessions list and the Models settings pane. + +--- + +## Scope Boundaries + +**In scope.** The eight units above, entirely within `macapp/Sources/GoCodeUI`, `macapp/Sources/GoCodeUI/DesignSystem`, and `macapp/Tests/GoCodeUITests`. + +**Out of scope.** +- **`ProjectSession` re-architecture.** It stays one observable owning phase, collections, and actions. In particular the missing `HarnessClient` injection seam (noted at `ProjectSessionActivityTests.swift:9-13`) is *not* introduced here, even though it would make U2/U4/U6 tests cleaner than a globally registered `URLProtocol`. +- **Visual restyling.** No token values change except the one new autoscroll threshold in U1. No colour, type, or spacing revisions. +- **Server / API redesign.** No Go changes. Two contract gaps were checked and found *not* to require server work: run-control acknowledgements already throw structurally (KTD-1), and `rewind_refused` is already a distinct error code (KTD-6). The one genuine absence — a dry-run preview for undo/delete — is worked around client-side (KTD-5) rather than met with a new endpoint. +- **`HarnessKit` changes.** None required. `HarnessClient.undo` still discards the server's `removed_from_step` / `remaining_messages` response body; surfacing it would be a `HarnessKit` change and is deferred. + +**Deferred to follow-up work.** +- D1: True caret-position-aware history navigation (needs an `NSTextView` bridge or a macOS 15 platform floor). See KTD-7. +- D2: Decoding the undo response so the *post-action* confirmation can report the server's real counts instead of only a pre-action client-derived preview. +- D3: A `HarnessClient` injection seam on `ProjectSession`, replacing the global `URLProtocol` registration in session tests. +- D4: `.disabled(...)` polish on the six lifecycle call sites, so a guarded action looks unavailable before it is pressed (U4 makes it *safe*; this would make it *obvious*). + +--- + +## Risks + +| ID | Risk | Mitigation | +|---|---|---| +| K1 | U2's `failed(String)` change breaks compilation in six view files and both existing load-state tests at once. | It runs early and alone; `ProjectSessionActivityTests` and `CollectionLoadStateTests` are the tripwires. Its diff is mechanical after the enum lands. | +| K2 | U1's geometry feedback loop could oscillate — a programmatic `scrollTo` re-pins, which triggers another scroll. | The pin is a threshold predicate, not an animation trigger; `scrollIfPinned` already only fires on item-id / length change, not on geometry change. Assert boundary and overscroll cases explicitly. | +| K3 | Alert presentation, `.onKeyPress`, and VoiceOver traits cannot be asserted headlessly on this test stack. | Testable logic is extracted into value types; wiring is pinned by source-scan reachability tests; a manual smoke is a required gate (see Verification Contract), not optional. | +| K4 | Source-scan reachability tests are brittle — a refactor that renames a symbol fails a test that is not describing a real regression. | Follow the existing precedent (`TranscriptFeatureReachabilityTests:31-38`): scan the whole module for a behaviour's presence rather than pinning a file/line. | +| K5 | U3 changes interrupt semantics; getting `cancelRequested` wrong turns a failed cooperative cancel into a surprise force-kill. | Explicit test: a failed first cancel leaves the second press cooperative. | +| K6 | Confirmations added to delete/undo/rewind/remove could become fatigue-inducing and get click-through-ed. | Confirmations are added only to the four genuinely destructive actions; the force-rewind wording is deliberately distinct from the ordinary rewind wording so the second one still reads as more severe. | +| K7 | Eight sequential slices on one fast-moving `main` (see `CLAUDE.md` merge discipline) risk a conflict-heavy long-lived branch. | One PR per unit, merged promptly; each unit is independently green. | + +--- + +## Assumptions + +Headless-mode calls made without asking, each recorded so they can be overridden: + +1. **A1 — Serial execution, not parallel.** Every unit shares at least one file with another (`ChatView.swift` across U1/U3/U7; `ProjectSession.swift` across U2/U4/U5/U6; `SessionsView.swift` across U2/U5/U6/U8), so the plan orders them rather than fanning them out. The epic's logical constraint (U3→U4→U5→U6) is preserved inside that order. +2. **A2 — U8 depends on U5.** The epic lists slice 8 as independent, but slice 8's provider-`Remove` item is a destructive confirmation and would otherwise need its own competing presentation. See the deviation note below. +3. **A3 — "Cursor-aware" (#998) is approximated by draft state, not caret position.** Justified by the `.macOS(.v14)` platform floor in `macapp/Package.swift`. See the deviation note. +4. **A4 — Undo/delete previews are client-derived and explicitly say when a count is unknown.** No fabricated numbers; no new server endpoint (KTD-5). +5. **A5 — `connectionError` is the acknowledgement-failure slot** rather than a new observable, because `InlineRunStatus` already renders it (KTD-1). +6. **A6 — `CollectionErrorState` shows the server's message verbatim**, consistent with `ModelSettingsView.swift:62-66`'s stated reasoning, rather than a summarised house style. +7. **A7 — One PR per unit.** Matches this repo's merge discipline; the epic's eight child issues map one-to-one to the eight units. +8. **A8 — The `.failed(String)` message is `error.localizedDescription`** (which for `HarnessError` is its `message`, via the `LocalizedError` conformance at `HarnessClient.swift:17-19`), so no extra unwrapping is needed at the 8 assignment sites. + +--- + +## Verification Contract + +**Per unit, in order, all run from `macapp/`:** + +1. `swift build` — clean. +2. `swift test` — green. Baseline for comparison: **177 tests passed, 0 failures at `8f2e412`** — this figure comes from the epic briefing (prior investigation) and was **not re-run while writing this plan**; re-establish it before U1 so later counts are comparable. +3. `swift format lint --strict --recursive Sources Tests` — clean. This is exactly the `format` job in `.github/workflows/macapp.yml:83`. +4. Test count must strictly increase per unit (every unit adds tests), and no previously passing test may be deleted to make a unit pass. + +**After the automated gates, per unit, against the real app and a real daemon** (`macapp/scripts/live-test.sh` builds `harnessd`; `HARNESS_TEST_BASE_URL` also enables the live suites): + +| Unit | Manual smoke | +|---|---| +| U1 | Start a long run, scroll up mid-stream, confirm the view stays put; scroll back to the bottom, confirm autoscroll resumes. | +| U2 | Kill `harnessd` mid-session, open Sessions / Activity / Models, confirm an inline error with a reason and a working Retry — not skeletons. | +| U3 | Deny an approval with the daemon stopped; confirm the failure is visible and the approval bar does not falsely clear. | +| U4 | Start a run, then attempt New / Fork / Undo; confirm each refuses with an explanation and nothing changes. | +| U5 | Delete a conversation and undo a turn; confirm each names what will be lost, and Cancel really cancels. | +| U6 | Edit a checkpointed file outside the app, attempt a restore; confirm the refusal is explained and the distinct "Restore Anyway" path works. | +| U7 | Press Up/Down in the composer with history present, then with a half-typed draft; confirm the draft is never clobbered. | +| U8 | Navigate the Sessions list and the Models pane by keyboard only, then with VoiceOver; confirm rows are reachable and named and that "Fetched N models" stays on screen. | + +Both CI jobs (`build-test` hermetic and `live-harnessd`) must be green before merge; re-run known-flaky checks rather than merging red. + +--- + +## Definition of Done + +- All eight units merged, each as its own PR closing its child issue (#992–#999), with #991 closed last. +- Every requirement R1–R11 has at least one test that fails if the behaviour regresses, and each unit's "core regression" test was demonstrably red before its implementation commit. +- `swift build`, `swift test`, and `swift format lint --strict --recursive Sources Tests` green on `main` after the final merge; test count strictly above the 177 baseline. +- The manual smoke table above is executed against a real `harnessd`, including the VoiceOver and keyboard-only pass for U8. +- Stale in-code notes retired: the `rewind_refused` NOTE at `SessionsView.swift:144-152` is deleted (U6), and `recallPreviousPrompt` has a production call site (U7). +- Deferred items D1–D4 are filed as follow-up issues rather than left in this document as the only record. +- `docs/logs/long-term-thinking-log.md` updated with the durable intent and success criteria for this epic, per `CLAUDE.md`. + +### Deviations from the epic text (reported, not suppressed) + +1. **#998's "cursor-aware" cannot be implemented literally on this platform floor.** `macapp/Package.swift:6` pins `.macOS(.v14)`. A SwiftUI text-selection/caret binding (`TextSelection`) is a macOS 15 API, so no supported way exists to read the caret from a SwiftUI `TextField` here. *Provenance: the platform floor is verified in the manifest; the API-availability claim is from my own knowledge of the SwiftUI release timeline and was not re-checked against the installed SDK in this session.* The plan therefore approximates the intent (never clobber an in-progress draft) via draft state, and defers true caret-awareness as D1. If literal caret-awareness is required, the cost is an `NSViewRepresentable` `NSTextView` composer — a much larger change than #998 implies. +2. **#999 (slice 8) is not independent of #996 (slice 5).** The epic's own rationale for ordering 5→6 is a shared destructive-confirmation presentation; slice 8's immediate provider `Remove` (`ModelSettingsView.swift:291-295`) is the same kind of action and needs the same component, so U8 is ordered after U5. Keeping it "independent" would mean either a second, competing confirmation implementation or leaving provider removal unconfirmed. +3. **File overlap makes the epic's "slices 1, 2, 7, 8 independent" true logically but not operationally.** U1, U3, and U7 all edit `ChatView.swift`; U2, U4, U5, and U6 all edit `ProjectSession.swift`. They are ordered serially for that reason (A1), not because of a hidden logical dependency. diff --git a/docs/residual-review-findings/feat-macapp-gui-hardening.md b/docs/residual-review-findings/feat-macapp-gui-hardening.md new file mode 100644 index 00000000..94a59cda --- /dev/null +++ b/docs/residual-review-findings/feat-macapp-gui-hardening.md @@ -0,0 +1,48 @@ +# Residual review findings — feat/macapp-gui-hardening (epic #991) + +Plan: `docs/plans/2026-07-30-001-feat-macapp-gui-hardening-plan.md` + +## Adversarial review summary + +An adversarial review pass ran across 4 dimensions (correctness, concurrency/races, safety-guard +completeness, accessibility) against the branch's 8 implemented slices.

Existing runs, pending-input, conversation, catalog, and rewind endpoints are consumed without wire changes. +- CLI commands, tools, wire formats, or integrations affected: None; TUI and web code are unchanged. +- Error states / validation changes: stale async completions are ignored; controls become single-flight; steering restores an unmodified draft after failure; stale collection data stays visible with a refresh failure. + +## Persistence and Compatibility + +- Schemas, migrations, caches, generated data, or ownership changes: None. +- Backward/forward compatibility and versioning: Client-only state ownership; compatible with the current harnessd API. +- Partial rollout and mixed-version behavior: A repaired app remains compatible with current harnessd.
