# V1 Public API Baseline
Status: Captured during Block 11.1.
Starting commit: `775c2ed406f03a73a9b0ca621dea5b4482468616`
Public import:
```dart
import 'package:scheduler_core/scheduler_core.dart';
```
The public library entry point is `lib/scheduler_core.dart`. It exports the
following source files:
- `src/models.dart`
- `src/application_commands.dart`
- `src/application_layer.dart`
- `src/application_management.dart`
- `src/application_recovery.dart`
- `src/backlog.dart`
- `src/child_tasks.dart`
- `src/document_mapping.dart`
- `src/free_slots.dart`
- `src/locked_time.dart`
- `src/occupancy_policy.dart`
- `src/persistence_contract.dart`
- `src/project_statistics.dart`
- `src/quick_capture.dart`
- `src/reminder_policy.dart`
- `src/repositories.dart`
- `src/scheduling_engine.dart`
- `src/task_actions.dart`
- `src/task_lifecycle.dart`
- `src/task_statistics.dart`
- `src/time_contracts.dart`
- `src/today_state.dart`
- `src/timeline_state.dart`
This baseline is used by later chunks to distinguish intentional breaking
changes from accidental API drift.

## Current model baseline
`TaskType` values:
- `flexible`
- `inflexible`
- `critical`
- `locked`
- `surprise`
- `freeSlot`
`TaskStatus` values:
- `planned`
- `active`
- `completed`
- `missed`
- `cancelled`
- `noLongerRelevant`
- `backlog`
Current notable model fields:
- `Task`: `id`, `title`, `projectId`, `type`, `status`, `priority`,
`reward`, `difficulty`, `durationMinutes`, `scheduledStart`, `scheduledEnd`,
`actualStart`, `actualEnd`, `completedAt`, `parentTaskId`, `backlogTags`,
`reminderOverride`, `createdAt`, `updatedAt`, `stats`
- `ProjectProfile`: `id`, `name`, `colorKey`, default priority/reward/
difficulty/reminder profile/duration fields, `archivedAt`
- `ProjectStatistics`: completion count, duration sample counts,
completion-time buckets, pushes-before-completion totals, reward/difficulty
distributions, and reminder-profile observations
- `TimeInterval`: `start`, `end`, optional `label`
- `TaskStatistics`: skip/push/backlog/missed/cancelled/late/locked-hour,
completed-after-shield, and push-before-completion counters. Parent/child
completion patterns are carried as activity metadata.
Known baseline gaps to preserve as explicit later work:
- `TaskStatus` does not include `pushed` or `skipped`; Chunk 11.2 resolves the
status/event distinction.
- `Task` does not yet have an explicit backlog-entered timestamp field.
- Instant ranges still use `DateTime`; locked recurrence dates, wall-clock
rules, clocks, IDs, and timezone resolution are explicit Chunk 11.4
contracts.
## Intentional API Changes After Baseline
Chunk 11.3 intentionally changed the public API:
- Added `DomainValidationCode` and `DomainValidationException`.

constructors.

- Added `SchedulingNotice.issueCode`, `SchedulingNotice.movementCode`,
`SchedulingNotice.conflictCode`, and immutable `SchedulingNotice.parameters`.
- Changed `SchedulingNotice` from a `const` constructor to a runtime constructor
so notice parameters can be defensively copied.
- Added a `SchedulingResult` assertion that each notice uses at most one issue,
movement, or conflict code.
Chunk 13.1 intentionally changed the public API:
- Added `src/task_lifecycle.dart` and exported it from `scheduler_core.dart`.
- Added `TaskTransitionCode`, `TaskActivityCode`, `TaskTransitionOutcomeCode`,

parent/child completion metadata.

result/service, suggestion policy/result types, and configured-default
resolution.

unit-of-work repository contracts for application orchestration.
- Added `OwnerSettings`, `ApplicationOperationRecord`,
`ApplicationSchedulingLoader`, and `InMemoryApplicationUnitOfWork`.
- Added in-memory staged transaction behavior with exactly-once operation
records and rollback on typed failures or persistence failures.
Chunk 14.2 intentionally changed the public API:

`TodayTimelineItem`, `TodayCompactState`, and `TodayPendingNotice`.

- Added `ApplicationUnitOfWork.read` so application queries can access
repositories without creating operation records.
- Added an optional `occurrenceDate` parameter to
`TimelineItemMapper.fromLockedOccurrence` so Today read models can produce
date-stable locked overlay IDs.
- Updated compact next-flexible selection so the current flexible item is not
also returned as `nextFlexibleItem`.
Chunk 14.3 intentionally changed the public API:
- Added `src/application_commands.dart` and exported it from
`scheduler_core.dart`.
- Added `ApplicationCommandCode`, `ApplicationChildTaskDraft`,
`ApplicationCommandReadHint`, `ApplicationCommandResult`, and
`V1ApplicationCommandUseCases`.
- Added atomic V1 commands for quick capture, backlog scheduling, flexible
push/backlog/completion, required task actions, surprise logging, protected
Free Slot create/update/remove, child break-up, and parent/child completion.
- Command results return changed tasks, persisted activities, project aggregate
updates, scheduler notices/changes/overlaps, child ids, and read refresh
hints.
- Application command failures use stable `ApplicationFailureCode` values for
not found, stale revision, no slot, validation, persistence, and duplicate
operation outcomes.

`DocumentMetadata`.

project statistics, locked blocks/overrides, activities, owner settings,
notice acknowledgements, operation records, scheduling snapshots, notices,
changes, overlaps, windows, intervals, civil dates, and wall times.
- Changed top-level document `toDocument` helpers/extensions to require owner
scope and V1 metadata where the domain model does not carry it directly.

fields, and V1 field sets for every persisted repository entity.

`DocumentMigrationEntity`, `DocumentMigrationStatus`,
`DocumentMigrationFailureCode`, `DocumentMigrationNoteCode`,
`DocumentMigrationProvenance`, `DocumentMigrationNote`,
`DocumentMigrationReport`, and `DocumentMigrationResult`.
- Migration results expose `document`, `isSuccess`, and `shouldWrite` so
persistence adapters can dry-run migrations and refuse to overwrite unreadable
source documents.
- Legacy backlog tasks now carry explicit provenance when `backlogEnteredAt` is
approximated from `createdAt`.
Chunk 15.4 intentionally changed the public API:
- Added adapter-neutral repository conflict/paging/record contracts:
`RepositoryFailureCode`, `RepositoryFailure`, `RepositoryMutationResult`,
`RepositoryRecord`, `RepositoryPageRequest`, `RepositoryPage`, and
`BacklogCandidateQuery`.
- Expanded `TaskRepository` with owner, project, parent, backlog-candidate,
local-day/window, record/revision, insert, and compare-and-set save methods.

paged queries, revision records, compare-and-set saves, duplicate insert
failures, archive methods, and date-scoped locked override lookup.
- Expanded application-layer repository interfaces for task activity owner
queries/appends, project statistics/settings revision saves, notice
acknowledgement insert/paging, and idempotent operation lookup/insert.
- In-memory unit-of-work repositories now track owner/revision metadata in the
staged transaction state.
Chunk 15.5 intentionally changed the public API:
- Added V1 collection/index contract types and constants:
`PersistenceCollections`, `PersistenceIndexDirection`,
`PersistenceIndexField`, `PersistenceIndexSpec`, `RepositoryQueryNames`, and
`PersistenceIndexCatalog`.
- Added bounded payload/retention guard surface:
`PersistencePayloadLimits`, `PersistenceGuardResult`, and
`PersistencePayloadGuard`.
- Added repository integrity failure codes for invalid revisions and owner
mismatches.
- Added `V1_BLOCK_16_REPOSITORY_ADAPTER_CHECKLIST.md` for the former document

## Repository contracts
The current repository surface is pure Dart and adapter-backed:
- Core legacy repository fakes remain in `scheduler_core` for existing domain
services and tests.
- The Block 19 repository abstraction lives in `scheduler_persistence`.
- The Block 19 conformance-tested memory adapter lives in
`scheduler_persistence_memory`.
- The Block 20 conformance-tested SQLite adapter lives in
`scheduler_persistence_sqlite`.
- Application transaction behavior is represented by
`InMemoryApplicationUnitOfWork`.
- Application read-query behavior uses `ApplicationUnitOfWork.read`, which
stages repository access without committing operation records.
Future SQLite adapter work must remain behind repository interfaces and must not
import storage APIs into the scheduling core.
