Status: experimental draft — storage-only, mirror of PR #648 (triathlon model storage).

What changed

• lib/data/hyrox_plan.dart — pure-Dart frozen plan, versioned JSON (v: 1); wrong-typed fields parse to null without throwing; validate() returns a human-readable problem or null. Presets: hyrox (fixed 8 stations), hyrox_doubles, hyrox_training / custom (free-form).
• lib/data/hyrox_store.dart — hyrox_session + hyrox_segment tables at schema rung 61 (60 is claimed by feat(triathlon): model and storage foundation #648; 59 by db: reunite rows stranded under a dead device_id (schema 59) #537). Same invariants as feat(triathlon): model and storage foundation #648: finalized = immutable (every write throws HyroxWriteError); started segments form a prefix, max one open segment, monotonic boundaries, no overlaps; gaps are PAUSES (totalSec vs movingSec/pauseSec). Same ops: create (armed only, no history), startSegment, transitionSegment, finishSegment, adjustBoundary (stamps manual both sides), adjustStart (only while nothing ended & no workout linked), removeBoundary (refuses workout-linked / started tail), linkWorkout (null-check fromRow, refuses dupes, verifies row count), finalize (finished, or abandoned/DNF with exactly one open cut segment and null duration; never-started → refused), applyOfflineBoundariesInTx (one transaction, rejects trailing/impossible boundaries).
• lib/state/hyrox_reconciler.dart — same burst rule as feat(triathlon): model and storage foundation #648: ≥3 double-taps (event 14) within 6 s, anchored on the FIRST tap (chained 0/6/12 s does NOT count); ±120 s clock-drift tolerance on read only; per-station minimum-duration floors; ignores sessions neither armed nor active; never touches finalized.
• lib/data/db.dart + lib/data/recent_slice.dart — migration rung oldV < 61, day delete/export with segment-overlap selection (OPEN segments of FINALIZED sessions bounded by COALESCE(session.end_ts, session.start_ts); live sessions keep open-overlap), ids read before delete, day delete cascades linked workouts (workout_route/split, session_sensor, strength_set, sessions) in the same txn, IN (...) chunked via _sqlVarChunks, restore protects discarded and compares updated_at, salvage + recent_slice registration.
• test/hyrox_model_storage_test.dart — model validation, lifecycle, timeline (prefix/overlap/pause), DNF finalize, cross-midnight delete/export, restore round-trip, reconciler bursts/floors/idempotence, adjustStart/removeBoundary/linkWorkout refusal paths.

Design decisions

• One segment per round (decided once, documented in hyrox_plan.dart): kind hyrox_round with round_index 1..8 and a station field (skierg, sled_push, sled_pull, burpee_broad_jump, rowing, farmers_carry, sandbag_lunges, wall_balls). The interleaved 1 km runs are NOT separate segments; round 8's segment runs to the finish line and includes the final 1 km run. The 16-segment run↔station alternative was rejected to keep exactly eight tap boundaries for eight rounds.
• No per-segment environment field: HYROX is an indoor arena event end to end, so needsGps is always false (unlike triathlon).
• Planned targets are plans, never measurements: per-round planned_distance_m / planned_reps / planned_cal (skierg & rowing: 1000 m or 50 cal, configurable) + optional goal_sec; distance_m requires distance_source.
• Rung 61, not 60: verified on main that 58 is current and no triathlon tables exist there; 60 belongs to feat(triathlon): model and storage foundation #648.
• kAlgoVersion unchanged; no existing derived analytics altered. All SQL uses bound params only.

Deferred (explicitly out of scope, like #648)

• No UI, no haptics, no live-tap wiring. The reconciler is implemented and tested but has no production caller yet — wiring it into the sync path is a follow-up PR.

Verification performed vs pending

Performed locally (sandbox has no Flutter SDK):

• Every new SQL statement executed against the real DDL extracted from hyrox_store.dart in SQLite (python3 sqlite3): closed, open, live open-overlap, cross-midnight, finalized-DNF (correctly does NOT match later days), day-delete + linked-workout cascade, and the store CRUD statement shapes — all pass.
• A Python mirror of the reconciler burst/floor rules over the test scenarios (burst anchoring, chained 0/6/12 rejection, floors, idempotence) — passes.
• Brace/paren balance and structure checks over all touched files; kAlgoVersion confirmed untouched.

CI (fork PR, branch feat/hyrox-model-storage):

• flutter analyze passes (two analyzer rounds fixed: declaration order, type promotion, fatal info-lints).
• Full flutter test --concurrency=1 suite: first run exposed 2 failures in the new day-export tests (missing PathProviderPlatform fake — fixed in bf556cfe); re-run in progress at time of writing.
  Pending: final green CI run on the test job.

Known open items

• Reconciler production caller (follow-up PR).
• Retention of band_events through a multi-hour race is unmeasured on hardware.
• Clock domain: strap RTC vs phone clock (±120 s read tolerance on read only).
• Interrupted-restore behavior for hyrox rows follows the existing salvage path; dedicated tests are in the suite.

Reviewer's Guide

This draft establishes HYROX model and storage foundations at schema rung 61: immutable, versioned round plans are persisted in transactional session/segment tables, integrated with database migration and backup flows, and reconstructed from validated band tap bursts, with extensive invariant and lifecycle tests. Review the timeline/state-machine rules, cross-midnight row selection and restore protection, and the explicit absence of a production reconciler caller; final full CI is still pending.

Explanation

The title "Feat/hyrox model storage" names the main change. The PR adds HYROX plan model, session and segment storage, and offline reconciliation support in lib/data and lib/state. It is short and identifies the primary feature. It uses a branch-style prefix ("Feat/"), which is a minor style issue and does not affect relevance.

Minor · Security & Privacy · Quick win

Make the HYROX day window match a DNF cut segment on the day it starts.

The comments at Lines 11169-11174 and Lines 10956-10957 say that a race belongs to a day when one of its segments starts that day. The open-segment branch does not follow that rule for a finalized race. It requires COALESCE(s.end_ts, s.start_ts, 0) > endSec. For an abandoned (DNF) race, session.end_ts is the end of the last closed segment. That value is at or before the open cut segment's start.

Trigger: a DNF race crosses midnight, and the cut segment starts after midnight. When the user deletes the second day, the cut segment matches no branch. The closed segments end on the previous day, the session starts on the previous day, and the open branch fails the > endSec test. The race stays on disk after a privacy delete. exportDaysDb leaves out the same race from that day's export. The same predicate is duplicated at Lines 10961-10970.

Fix: also match any segment whose start_ts is inside the window. Put the predicate in one shared constant so the export and delete paths cannot drift apart.

🔒️ Proposed fix (apply to both copies, or extract one constant)

             'UNION SELECT session_id FROM hyrox_segment '
             'WHERE start_ts IS NOT NULL AND start_ts < ? '
-            'AND ( (end_ts IS NOT NULL AND end_ts > ?) '
+            'AND ( start_ts >= ? '
+            '   OR (end_ts IS NOT NULL AND end_ts > ?) '
             '   OR (end_ts IS NULL AND start_ts < ? '

Update the argument lists to [startSec, endSec, endSec, startSec, startSec, endSec, endSec].

Update the HYROX day-window predicate used by exportDaysDb and the delete path
so an open segment matches when its start_ts falls within the window, including
for finalized DNF races. Put the predicate in one shared constant so both paths

Major · Data Integrity & Integration · Heavy lift

Protect imported segment rows when the parent session row is skipped.

The restore loop skips an imported hyrox_session row when the local row has an equal or newer updated_at (isHyroxProtected(id, row)). For hyrox_segment rows, the code calls isHyroxProtected(sessionId, null). With row == null, the function returns true only for locally discarded races. As a result, a skipped parent never protects its segments.

Trigger: the user restores an older backup over a race that exists locally and has newer boundaries, or that is already finalized. The local hyrox_session row is kept. INSERT OR REPLACE then overwrites every hyrox_segment row with the older boundaries. The parent's start_ts, end_ts, status and finalized_at then disagree with its segments. For a finalized race, this rewrites a record that HyroxDb treats as immutable. The comment at Line 11837 says segments follow their parent's verdict, and the code does not do that.

Fix: record each session id that the merge skips, and check that set for segment rows. hyrox_session is merged before hyrox_segment in _restoreTables, so the set is complete before the segment pass starts. Also protect the segments when the backup carries segments for a local race but has no session row for it.

🐛 Proposed fix

                 if (t == 'hyrox_session' &&
                     isHyroxProtected('${row['id']}', row)) {
+                  skippedHyrox.add('${row['id']}');
                   continue; // locally discarded, or newer than the snapshot
                 }
                 if (t == 'hyrox_segment' &&
-                    isHyroxProtected('${row['session_id']}', null)) {
+                    (isHyroxProtected('${row['session_id']}', null) ||
+                        skippedHyrox.contains('${row['session_id']}'))) {
                   continue;
                 }

Minor · Functional Correctness · Quick win

Refuse to merge into the final segment of a finished session, or reset its status.

removeBoundary does not recompute status. Consider a session with status finished where idx + 1 is the final segment. The merge closes segment idx at the final end and clears the final segment. The session stays finished, but its last segment is now unstarted, and no write can progress the race:

• finishSegment needs exactly one open segment, and there is none.
• transitionSegment needs an open current segment.
• finalize for finished rejects the unstarted last segment.

The only exit is to relabel the race as abandoned with updateSession, which records a finished race as a DNF.

Fix: reject the merge when right is the last segment and right.endTs != null. As an alternative, define a state for this case and pass an explicit status to _recomputeSessionBounds.

🐛 Proposed guard

       if (left.workoutId != null || right.workoutId != null) {
         throw HyroxWriteError(
           'a segment is linked to a workout — unlink it before removing the boundary',
         );
       }
+      if (right.idx == segs.length - 1 && right.endTs != null) {
+        throw HyroxWriteError(

HYROX follow-up PRs (stacked on this PR's branch feat/hyrox-model-storage)

This storage PR (#663, mirrored as fork PR BucciMobile#11) is the base of a
stacked follow-up chain in the fork — each PR's base is the previous one, so they land
in order once this one is merged:

Fork PR	Branch	Scope
edge-copy#12	feat/hyrox-reconciler-caller	Offline reconciler wired into the sync path (AppState._onDataStored): rebuilds the active session's round boundaries from stored band taps after every durable persist. Idempotent, finalized/discarded never touched.
edge-copy#13	feat/hyrox-live-taps	Live tracking while connected: double-tap bursts (event 14, >=3 taps in 6 s anchored on the first, chained 0/6/12 s rejected, per-station floors) close rounds in real time via startSegment/transitionSegment/finishSegment, stamped gesture. Live path only, never the headless drain.
edge-copy#14	feat/hyrox-workout-banking	Every closed round is banked as a sessions row and linked (workout_id), so zones/splits/analytics and Apple Health export (existing sessions path) see each round. Idempotent; day-delete cascade already covered here.
edge-copy#15	feat/hyrox-ui	First UI: arm presets, live round list with total/moving/pause, per-round post-hoc corrections (adjustBoundary/removeBoundary/adjustStart), DNF/discard/save. Entry: Activity tab → HYROX card; route /hyrox.

Deliberately deferred: haptics/vibration feedback on the band (lowest priority), and a
full time-picker for boundary corrections (screen currently offers −60 s move + merge).

Verification: storage branch CI is green (flutter analyze + full flutter test);
CodeRabbit findings on #663 (DNF cross-midnight day window, restore protection of skipped
parents' segments, removeBoundary into closed final segment) are fixed in 848298a3.
Follow-up branches carry per-step sqflite_ffi tests; their CI runs on the fork.

Note: PRs #12–#15 need a rebase onto main once #663 merges (they are stacked on the
feature branch, not on main).

Review comments at @lib/data/db.dart:
- Line 12314: The restore guard treats every parent with finalized_at as
protected before checking whether its segments are complete, preventing
interrupted restores from resuming. Update the restore logic around the
r['status'] condition so finalized protection applies only after segment
completeness is confirmed, while discarded protection remains unconditional;
alternatively, restore each parent and its segments atomically.
- Line 12389: Update the query around the `r['status'] == 'discarded'` check to
include `finalized_at` and protect complete finalized triathlons regardless of
the imported timestamp. Preserve the existing recovery path for incomplete
restores.
- Line 11546: Update the open-cut-segment overlap predicate so abandoned races
are treated as terminal rather than live indefinitely, while preserving the
existing behavior for active races. Apply the same terminal-state bound to the
export predicate so both queries exclude abandoned races from later-day overlap
results.

Review comments at @lib/data/hyrox_plan.dart:
- Around line 272-275: Update the calorie-target validation in validate() to
reject any non-null plannedCal when _isFixedRacePreset(preset) is true, while
preserving the existing positive-value check for plans where calorie targets are
allowed.

Review comments at @lib/data/hyrox_store.dart:
- Line 1157: Update the writable-status validation around the `writable`
allowlist in the Hyrox store so note-only updates to an already-finished session
are accepted without changing its finished status; allow `finished` only when
the persisted status is already `finished`, or otherwise separate note updates
from lifecycle transitions. Apply the same correction to the corresponding
validation in the Triathlon store.
- Line 848: When updating the moved boundary via right.copyWith, preserve the
original tap cluster as consumed so reconciliation cannot reuse it after an
earlier timestamp leaves it above the new floor; apply the same correction in
the corresponding triathlon boundary-move path without bypassing existing
safeguards.

Review comments at @lib/data/triathlon_plan.dart:
- Line 196: Update the t1 and t2 TriSegmentPlan constructors in race() to pass
through the corresponding values from goalSec, preserving null when a transition
goal is absent.

Review comments at @lib/data/triathlon_store.dart:
- Line 410: Update HyroxDb.create’s corresponding validation in the triathlon
creation flow to reject a session.preset that differs from the frozen plan’s

Do not treat abandoned triathlons as indefinitely live.

An abandoned, unfinalized race can retain an open cut segment. TriathlonDb.updateSession permits this state (lib/data/triathlon_store.dart, Line 967). This condition treats that race as overlapping every later day.

Deleting an unrelated later day therefore deletes the older race and its linked workouts. Add a terminal-state bound instead of treating every non-finalized status as live. Correct the export predicate at Line 11260 as well.

Update the open-cut-segment overlap predicate so abandoned races are treated as terminal rather than live indefinitely, while preserving the existing behavior for active races. Apply the same terminal-state bound to the export predicate so both queries exclude abandoned races from later-day overlap results.

Allow an interrupted finalized-race restore to resume.

Restore commits hyrox_session before hyrox_segment. If the process stops between those passes, the local parent has finalized_at but lacks its segments. On retry, this condition protects the parent before the completeness check runs. The segment guard then skips every imported segment, so repeating the restore cannot repair the race.

Apply finalized protection only after confirming segment completeness, or restore each parent and its segments atomically. Keep discarded protection unconditional.

Protect complete finalized triathlons from newer snapshots.

A complete local finalized race enters triLastEdit, but not protectedTriathlons. If another phone supplies a newer unfinalized snapshot, restore replaces the parent and its segments. This clears finalized_at and replaces an immutable record.

TriathlonDb._requireWritable explicitly refuses changes to finalized races (lib/data/triathlon_store.dart, Line 1237). Include finalized_at in this query and protect complete finalized races regardless of the imported timestamp. Preserve recovery for incomplete restores.

Reject calorie targets in fixed-race plans.

A hyrox or hyrox_doubles plan with canonical stations and round indices can set plannedCal: 50 and still pass validate(). This contradicts the documented restriction that calorie targets are available only for free-form training plans. Reject non-null plannedCal when _isFixedRacePreset(preset) is true.

Exclude the original tap cluster when moving its boundary earlier.

In a two-round training session, suppose a cluster at 1300 opened round 2. Moving that boundary to 1200 leaves the original cluster above the new reconciliation floor. Its 100-second elapsed time passes the training floor, so reconciliation uses the same cluster again and finishes round 2 at 1300.

Preserve the original cluster as consumed when correcting its timestamp. The same failure exists in lib/data/triathlon_store.dart, Line 751, when the moved boundary leaves enough time to pass the next segment’s floor.

Check planned segment count before finishing or finalizing a race.

finishSegment detects the final segment from the number of stored rows. If restore leaves a session with fewer rows than its plan, the last stored row can pass as the final segment. Example: a five-segment plan with rows 0 through 3 stored. Closing row 3 passes the check at lib/data/triathlon_store.dart:638, and the session is marked finished. finalize then freezes it, and its timeline check (_validateTimeline) receives only the stored rows and cannot detect the missing segment.

Restore can produce this row set. A cut-off restore can leave a parent with only some of its segments (lib/data/db.dart:12359-12365). Until a later import repairs it, nothing blocks finishing or finalizing that session.

Compare the stored segment rows with the frozen plan before accepting either operation. Reject the session if the rows do not match the plan's segment count and indices.

Keep a removed boundary excluded from reconciliation.

Suppose a tap cluster at 1400 closes a swim that started at 1000. Removing that boundary reopens the swim and clears its successor. The next reconciliation reads the same taps, passes the 300-second swim floor, and restores the removed boundary.

Persist the removed cluster as excluded and honor that exclusion during triathlon reconciliation. Clearing the segment timestamps alone does not preserve the correction.

Exclude the accepted cluster, not only its first event.

For an accepted cluster [1600, 1602, 1604, 1606], removeBoundary stores the anchor 1600 as excluded. This filter leaves [1602, 1604, 1606]. Those three taps still pass the gate, so reconciliation restores the removed boundary at 1602.

Keep the original cluster grouping and reject the entire excluded cluster before deriving boundaries. Removing only the anchor works for exactly three taps but fails for longer bursts.

Read and derive the timeline inside the apply transaction.

A swim starting at 1000 permits a derived boundary at 1320. If adjustStart commits a correction to 1310 before this method starts its apply transaction, the store still accepts that boundary: its checks require only matching kinds and nondecreasing timestamps. The result is a 10-second swim despite the 300-second gate.

Read the session, read the taps, derive the boundaries, and apply them in one transaction. The later segment reread does not revalidate the original decision.

Slide past rejected taps before discarding a valid burst.

For eligible taps [1000, 1006, 1007, 1008], this loop creates [1000, 1006] and [1007, 1008]. Both clusters are rejected. However, [1006, 1007, 1008] satisfies the three-tap/six-second gate.

When a candidate window has insufficient taps, advance its start instead of permanently consuming the whole candidate. Apply the same correction to lib/state/hyrox_reconciler.dart, Line 215 through Line 221.
