Setline

Setline is a native iPhone workout player. Follow an authored programme, record actual sets, control rest, and compare progress with targets you set. Active workouts run and save on the device without waiting for a network request.

The app lives in ios/. The public landing, privacy and support pages are owned by the shared ios-landings factory (PRODUCT=setline), at setline.significanthobbies.com. This repository has no separate landing source or product-specific backend.

Using it

Start with Today or an authored workout. Complete sets in programme order and record what happened. Skips, extra sets and Do later are explicit session changes; they do not silently rewrite the programme. Completed workouts appear in history, and You contains progress and periodic benchmark check-ins.

The app includes the owner-authored dated 12-week programme, custom workout creation and duplication, one bounded 1–16 week custom programme, structured set targets, partial/drop segments, set and rest timing, and a movement catalogue. Load recommendations require an explicit choice and affect only the session.

Keep a versioned JSON export as a backup. It includes workout state, templates, and the custom programme; import previews the replacement before applying it. Private iCloud continuity is implemented, but two-device convergence remains unverified on hardware. Optional Significant Hobbies Hub sync shares completed session summaries after local writes. Neither is required to run a workout.

In Settings, approve existing history for the displayed Hub account before its first sync. That approval persists locally; another account cannot upload those workouts or take over waiting changes. Workouts received through iCloud retain their recorded Hub owner. Finish an active workout before approving history.

Hub downloads commit locally before their sync cursor advances. Native workout details are preserved when their summary returns from the Hub. Newly imported summaries are labelled explicitly, carry no invented set data, and are not uploaded again as new workouts. Untagged legacy records remain preserved when a summary has the same ID. These guarantees are covered by synthetic native tests; they do not establish physical signed-in convergence.

Current installation evidence

Version 1.0.0 build 10 from exact source af7071d passed CI 34334618829, then signed Release and strict/deep signature verification. It installed on the owner's connected iPhone on 9 September 2026 as a same-bundle update, with no uninstall/reset. The app was not launched and account sync/recovery was not run. Both this artifact and the previous c4f9616 signed app are retained locally. Installation receipt. Physical workout use, real account continuity, iCloud convergence and public availability remain unqualified in issue 77.

Local development and checks

pnpm install --frozen-lockfile
pnpm check                     # repository contracts and code health
pnpm quality:native            # generate, simulator tests, Release build, coverage

For native-only iteration, ios/scripts/check.sh also accepts SETLINE_SIMULATOR_DESTINATION for an available iPhone simulator. Marketing changes belong in ../ios-landings/products/setline/, following that repository's instructions.

Retained work

Physical iPhone use, real iCloud convergence, and signed-in Hub continuity need qualification. Apple Health, Apple Watch, CrossFit session formats, range-of-motion assessments and on-device workout generation remain planned. Coaching and social features are outside the current workout execution scope.

Source, product planning and GitHub Issues live in this repository. The private Fleet catalog records evidence and release limits without owning this app.

Missing Hub summary recovery (9 September 2026)

The decoder now accepts the Hub contract’s date-only and fractional-second occurredOn values. A native coordinator regression reproduced the previous loss: the cursor advanced while a valid summary never reached saved history.

In Settings, Recover missing Hub summaries checks the approved account’s history through PersonalSyncKit 629d8e7, including equal versions already acknowledged by an older app. Existing local workouts and summaries are kept; a removal during the request is not undone. Active workouts defer the operation. Recovery cannot recreate set details that were never part of the Hub summary.

All pages must arrive and the local document must be saved before replay cursor bookkeeping. Failed saves, interrupted pagination and cancellation remain retryable. The shared limit is 100 pages of at most 500 changes, with no partial history acknowledged. This action is opt-in and does not reset a live cursor. Actual signed-in recovery, physical workout use and two-device iCloud convergence remain in issue 77. Build 10 from recovery source c4f9616 was installed on 9 September; installation did not qualify a physical workout or signed-in recovery. General quality passes with existing limits unchanged. Its development-only ESLint dependency now resolves js-yaml 4.3.2, clearing the newly published high advisory without adding a runtime dependency.

The final local XcodeBuildMCP gate passed 232 tests (17 UI), with the existing iCloud-credential test skipped. Production coverage is 80.6953% (11,675/14,468 lines), above the unchanged 80.60% floor.

Unsigned Release compilation also passed through XcodeBuildMCP on stable Xcode 26.6.

Actual caller isolation proof (9 September 2026)

Two additional tests invoke AppModel.approveHubAccount, account restoration and syncWithPlatform with memory-only synthetic identities and an isolated URL session. Switching from A to B during a held response preserves A's queue and document, rejects its downloaded summary/cursor, and records no successful sync. Starting a workout and recording a set while a pull is held remains fully local; the released response cannot commit history, cursor or success during that workout. After an offline finish and reopen, explicit recovery preserves the native set segments and imports exactly one tagged Hub summary. No new product defect was reproduced by these scenarios.

The shared 31f6b4e pin adds an explicit composition initializer for isolated testing; default production connection behavior is unchanged. Installed build 10 from c4f9616 remains unchanged. Real account/provider handoff, physical workouts, iCloud convergence and public distribution remain in issue 77.

General quality passes. The full native suite passes 234 tests (17 UI), with the existing iCloud-credential test skipped. Production coverage is 81.2483% (11,755/14,468 lines), above the unchanged 80.60% floor. Unsigned Release compilation also passes on stable Xcode 26.6.

Workout interruption and detailed history (9 September 2026)

An actual isolated simulator workout now proves recording, adjusted rest, termination/relaunch, resume, finish and a second reopen with exact set values and authored/performed order. This exposed and fixed a display-only off-by-one: performed positions were stored correctly as one-based but displayed with another increment. Existing saves need no migration.

The DEBUG-only UUID fixture persists across relaunch without using owner data, cloud, account clients or notifications. It refuses malformed paths/reset modes, never reseeds an existing file, and cleans only its own directory/defaults. Five focused UI/fixture tests pass. The before/after receipt retains the real failed screenshot, saved values and corrected reopened history. Physical workouts, real account recovery, iCloud convergence and distribution remain in issue 77; installed build 10/source c4f9616 was not changed.

The full required native gate passes 239 tests (18 UI), with the existing credential test skipped; unsigned Release passes and coverage is 81.4891% (11,842/14,532), above the unchanged 80.60% floor. General quality also passes.
