  Reuse _SearchBar instead of re-implementing it inline.
  The search field built here duplicates _SearchBar (Lines 177-227) but loses the clear-button affordance and drifts the styling. Hoist _SearchBar (or a shared component) and reuse it in both screens to keep behavior consistent and eliminate the copy.

  Health Connect color diverges from session_details_sheet.dart.
  This file declares _hcColor = Color(0xFF00BFA5), but session_details_sheet.dart line 11 declares _hcColor = Color(0xFF4ECDC4) — both labelled "Health Connect" but rendered in different teals across screens. Centralize this in AppColors (and remove both private constants) so the brand color stays consistent across the profile and history surfaces.

  ⚠️ Potential issue | 🟠 Major | 🏗️ Heavy lift
  Volume strings hardcode "kg" — breaks for non-metric users.
  SessionCard (line 145) and RecentSessionTile (lines 261-263) build the volume label with a literal ' kg'/'kg'. This bypasses SettingsProvider.unitLabel / formatWeight, so users on imperial units see the wrong unit and unconverted weight on every history list and dashboard recent-tile. Same anti-pattern as exercise_details_sheet.dart line 197.
  Either add an optional unitLabel/formatVolume parameter on these cards (passed by callers that already have access to SettingsProvider), or accept a precomputed volumeLabel string and let the caller format it.

  ⚠️ Potential issue | 🟡 Minor | ⚡ Quick win
  Regex-based value parsing is fragile.
  Stripping [^0-9.] to obtain numericValue and [0-9.] to obtain the suffix breaks for several plausible inputs the dashboard already produces:

  • "1.5k" → numeric 1.5, animates 0 → 1.5 instead of 0 → 1500, so the counter is meaningless for kilo-suffixed values.
  • "1,000" (locale-formatted) → numeric 1000, suffix ",", displayed as "1000,".
  • "-5" or "$100" → minus/dollar sign survives in the suffix in the wrong position.
    Prefer accepting an explicit double? animatedValue and String displaySuffix from the caller (it already knows the raw number), and falling back to plain Text(value) when no animated value is provided.

  Avoid hex literal; promote _hcColor to AppColors.
  AppColors's own header states "Never use hex literals in widget files — always reference AppColors or AppTheme aliases." profile_sections.dart defines _hcColor = Color(0xFF00BFA5) for the same Health Connect feature, and this file uses 0xFF4ECDC4 — two different brand colors for the same concept. Centralize this in AppColors (e.g., static const healthConnect = Color(0xFF00BFA5)) and reference it from both files.

  Hex literal violates this file's own contract; also missing const.
  selectedColor: Color(0x4D6C5CE7) is a hardcoded primary color with an alpha — exactly the pattern the AppColors header tells callers to avoid.

  🧩 Analysis chain

  🌐 Web query: `In Dart, does `int.clamp(min, max)` return `int` or `num`, and does it need `.toInt()` before passing it to a `ValueChanged` callback?` 💡 Result: `int.clamp(min, max)` is typed as returning `num` (not `int`). The `num` base signature is `num clamp(num lowerLimit, num upperLimit)` [1], and `int`’s `clamp` return type is shown as `→ num` as well [2]. Because the static type is `num`, if you pass the result to a `ValueChanged` callback, you generally need to convert it to `int` (e.g., `onChanged(value.clamp(… , …).toInt())`). The `.toInt()` is required whenever the callback parameter is statically `int`, since `num` is not assignable to `int`. Note: there is discussion that the runtime returns an `int` when all arguments are `int`s, but the static signature historically remained `num clamp(num, num)` [3]. So for type safety, use `.toInt()` when the receiving API expects `int`. Citations:

  Keep the AI dependency abstract at the provider boundary.
  Providing GeminiAiService directly here makes downstream UI import the concrete backend just to observe AI state. Expose an interface- or manager-typed dependency from the composition root instead, so backend swaps stay localized and screens remain on the intended layer. Based on learnings: "All service interfaces must be defined in lib/services/interfaces/ and implemented by concrete services" and "New features should follow the pattern: Model → Interface → Storage → Manager → Provider → Screen → Tests".

rest with a brief reason, keep changes minimal, and validate.

Inline comments:
In `@docs/superpowers/specs/2026-06-11-sleep-hr-chart-design.md`:
- Line 120: The markdown linting violations in the spec file need to be fixed at
two locations. At line 120, add the language identifier `text` to the opening
code fence (change ``` to ```text) and ensure proper blank-line separation
before and after the fenced code block. At line 162, add a blank line before the
opening ```dart fence to provide proper separation between the preceding text
and the fenced code block. These changes will resolve the markdownlint warnings
for missing language specifiers and improper fence spacing.

In `@workout-logger/android/app/build.gradle.kts`:
- Around line 63-68: The release build signing configuration currently falls
back to the debug key when the release keystore is missing, which can silently
produce incorrectly-signed production artifacts. Remove the fallback logic that
assigns signingConfigs.getByName("debug") when releaseConfig.storeFile is null.
Instead, explicitly throw an error or fail the build when the release signing
configuration is not properly set up, ensuring that release artifacts are never
accidentally signed with the debug key in CI or release pipelines.

In `@workout-logger/lib/main.dart`:
- Around line 193-195: The fire-and-forget calls to ReadinessManager.refresh()
lack error handling, which can cause unhandled Flutter errors if the async
operation fails. At workout-logger/lib/main.dart#L193-195, modify the
readiness.refresh() call to attach .catchError(...) and log any failure so
startup remains non-blocking. At
workout-logger/lib/screens/profile_screen.dart#L177-179, similarly attach
.catchError(...) inside the unawaited(...) call that wraps readiness.refresh()
before showing the success snack, ensuring any async errors are caught and
logged without blocking the UI.

In `@workout-logger/lib/models/models.dart`:
- Around line 1091-1098: The hasStages getter only checks for lightMinutes,
deepMinutes, and remMinutes, but does not account for cases where Health Connect
returns a stage timeline containing only awake intervals. This causes the
minutes getter to incorrectly fall back to the raw session span calculation,
overstating actual sleep time. Modify the hasStages getter to also check for
awakeMinutes or whether stageTimeline is not empty, so that stage data including
only awake minutes is properly recognized as staged data and the minutes getter
uses the accurate stage-based calculation instead of falling back to the raw
span.

In `@workout-logger/lib/models/sleep_hr_models.dart`:
- Around line 72-79: The SleepHrSnapshot constructor at lines 72-79 and a
similar constructor at lines 148-155 are storing mutable List inputs directly
(segments, stageStats, and buckets respectively) without defensive copying. This
allows callers to mutate these lists after construction, violating immutability
expectations. At each constructor location, defensively copy each list field by
wrapping it with List.from() or using the spread operator to create a new list
instance. This ensures that external mutations to the original list cannot
affect the model's internal state, and all modifications must go through
copyWith() as per coding guidelines.

In `@workout-logger/lib/models/workout_hr_models.dart`:
- Around line 68-92: The WorkoutHrAnalysis class exposes mutable List references
for curve, rests, and exercises fields, allowing callers to mutate them directly
after construction which bypasses controlled updates. To fix this, wrap each of
these three list fields with List.unmodifiable() in the constructor to enforce
immutability boundaries. Additionally, implement a copyWith() method on the
WorkoutHrAnalysis class that accepts optional parameters for all fields (start,
end, avgBpm, peakBpm, minBpm, curve, rests, exercises, and hasRestAnalysis) and
returns a new WorkoutHrAnalysis instance with the provided values or the
existing ones if not provided, ensuring all model mutations go through this
controlled method rather than direct mutation.

In `@workout-logger/lib/screens/sleep_detail_screen.dart`:
- Around line 126-142: The `_ist()` method hardcodes the IST timezone offset
(UTC+05:30) which causes incorrect sleep times for users outside that timezone.
Replace the hardcoded duration conversion in the `_ist()` method with
`dt.toLocal()` to use the device's actual local timezone. Additionally, update
the display text in the build method to remove the hardcoded "IST" label since
the time is now shown in device-local time rather than a fixed timezone.

Outside diff comments:
In @.github/workflows/release.yml:
- Around line 40-43: Add a test execution step to the release workflow that runs
the Flutter test suite before any APK publishing occurs. After the "Install
dependencies" step at lines 40-43, insert a step to execute flutter test and
configure it to fail the workflow if tests do not pass. Apply the same test
execution gate at the other affected locations in the workflow (lines 122-130
and 151-172) to ensure tests run and pass before any release artifacts are
published, preventing regressions from being shipped.

In `@workout-logger/lib/models/models.dart`:
- Around line 978-990: Wrap the mutable list fields with List.unmodifiable(...)
to enforce immutability at model boundaries. In QuestionSpec.fromJson, wrap the
options list assignment with List.unmodifiable() to prevent external mutation of
the model state. Apply the same pattern to AnswerSpec.selected,
PendingQuestions.questions, and SleepPeriod.stageTimeline in their respective
constructors and fromJson factory methods, ensuring all list fields are made
unmodifiable when assigned from external input to comply with the guideline that
all model mutations must go through copyWith().

In `@workout-logger/lib/screens/ai_program_generator_screen.dart`:
- Around line 480-490: The Text widget displaying phase.name is positioned
before a Spacer in a Row, which allows the AI-generated name to overflow when it
is long. Wrap the Text widget containing phase.name in an Expanded or Flexible
widget to constrain its width, and add overflow: TextOverflow.ellipsis to the
TextStyle to ensure long names are truncated with an ellipsis rather than
overflowing the layout.

In `@workout-logger/lib/screens/home_screen.dart`:
- Around line 118-122: The condition in the WorkoutFlowScreen navigation is
incorrectly using OR logic between the started flag and the resume conflict
action. When resuming an active workout, a new routine was not started, so
pushing WorkoutFlowScreen with the tapped routine will display the wrong
routine. Fix this by changing the condition to only push the WorkoutFlowScreen
when a new workout was actually started (when started is true), and remove
StartWorkoutConflictAction.resume from the OR condition, since resuming should
not navigate to a new workout screen with the tapped routine.
- Around line 1235-1241: The catch block in the weekly insights generation
try-catch statement silently ignores network and API errors by doing nothing.
Replace the empty catch block that catches the exception with code that displays
an error message to the user, such as a SnackBar or inline error message. Check
the mounted state before showing the error to ensure the widget is still in the
tree, and provide a clear user-facing error message so they understand that the
generation failed and can retry if needed.

In `@workout-logger/lib/screens/profile_screen.dart`:
- Around line 211-214: The condition checking the share result status in the
profile_screen.dart file incorrectly treats ShareResultStatus.dismissed as a
success case. When a user dismisses the share dialog, no backup is actually
created, so showing "Backup exported successfully!" is misleading. Refactor the
if statement to only show the success message when the result status equals
ShareResultStatus.success. For the ShareResultStatus.dismissed case, handle it
separately with a distinct message (e.g., indicating the user cancelled the
backup operation) to accurately communicate what happened to the user.

In `@workout-logger/lib/screens/widgets/exercise_details_sheet.dart`:
- Around line 213-234: The success trend banner is displayed whenever
growthModel has a sufficient r2 value, but it does not validate that the slope
is positive. This causes negative slopes to display with a green "trending up"
icon and confusing messages like "+-5.0 lb volume/week". Add an additional
condition to check that growthModel.slope is greater than 0 in the conditional
that guards the Container widget with the success styling,
Icon(Icons.trending_up_rounded), and the Text showing the slope calculation.
This ensures the success banner only appears for positive growth trends, not
negative ones.```
