Subject: [PATCH 1/8] feat: add TimeEntry CRUD backend (service, controller,
 routes)

Implements the backend for time tracking MVP:
- TimeEntryService: CRUD operations via OpenRegister ObjectService
- TimeEntryController: REST endpoints POST/GET/DELETE /api/time-entries
- Routes registered in appinfo/routes.php
- Validation: duration > 0, date required, taskId must exist
- Owner-only delete enforcement
- Authentication check (403 for unauthenticated users)

-# Admin Settings MVP
+# Time Tracking MVP
 
-**Status**: pr-created
-**Spec reference**: [admin-user-settings](../../specs/admin-user-settings.md)
+**Status**: approved
+**Spec reference**: [time-tracking](../../specs/time-tracking.md)
 **Priority**: MVP
 
 ## Summary
 
-Implement the admin settings page for Planix. This is the first MVP feature that wires up
-the backend settings API with a proper frontend admin page. The user settings dialog is
-deferred to a follow-up change — this change focuses on the admin side only.
+Add basic time tracking to Planix. Users can log time entries against tasks
+and view a simple timesheet. No complex reporting — just CRUD for time entries
+and a per-task time log display.
 
-## Scope
+## Scope (MVP only — 2 tasks)
 
-- Admin settings page under Nextcloud Administration → Planix
-- CnVersionInfoCard as the first section
-- Default columns configuration (editable ordered list)
-- OpenRegister initialization status and trigger button
-- Backend: SettingsController with read/write endpoints via IAppConfig
-- Frontend: AdminRoot.vue with CnVersionInfoCard + CnSettingsSection components
+- Backend: TimeEntry service + controller (CRUD via OpenRegister)
+- Frontend: Time log section on task detail + simple "Log time" form
 
 ## Out of scope
 
-- User settings dialog (NcAppSettingsDialog) — separate change
-- Procest bridge settings — V1, separate change
-- Notification preferences — separate change
+- Timesheet views, burndown charts, CSV export (V1)
+- Timer/stopwatch functionality (V1)
+- Approval workflows (V1)
 
 ## Architecture
 
-- Backend: `SettingsController` exposes `GET /api/settings` and `POST /api/settings`
-- Settings stored via `OCP\IAppConfig` (server-side, admin-only)
-- Frontend: Vue 2 + `@conduction/nextcloud-vue` components
-- No new database tables or OpenRegister entities
-
-## Risks
-
-- CnVersionInfoCard and CnSettingsSection require `@conduction/nextcloud-vue` — verify the
-  dependency is declared in package.json
-- OpenRegister initialization depends on OpenRegister being installed and enabled
+- TimeEntry stored as OpenRegister objects (schema already defined in register)
+- Backend: TimeEntryController with standard CRUD endpoints
+- Frontend: TimeLog.vue component embedded in task detail view

+# Time Tracking Specification
+
+**Status**: idea
+
+**Standards**: Schema.org QuantitativeValue, iCalendar ESTIMATED-DURATION (RFC 7986), OpenProject spentTime model
+**Feature tier**: MVP
+
+**OpenSpec changes:** _(links to openspec/changes/ directories when in-progress or done)_
+
+## Purpose
+
+Time tracking in Planix allows team members to estimate task effort and log actual time spent. This enables project capacity planning, billing, and retrospective analysis. Each task carries an estimate (minutes); actual time is logged as separate TimeEntry objects — multiple per task, one per work session. Users view their logged time in a personal timesheet. Project leads view aggregated time reports (V1). Time tracking is intentionally simple in MVP: manual entry only (no live timer).
+
+## Data Model
+
+See [ARCHITECTURE.md](../../docs/ARCHITECTURE.md) for full TimeEntry entity definition.
+
+**TimeEntry summary**:
+
+| Property | Type | Required | Default |
+|----------|------|----------|---------|

+
+## Requirements
+
+### Requirement: Time Estimate [MVP]
+The system MUST allow users to set a time estimate on a task.
+
+#### Scenario: Set estimate on task
+- GIVEN a user is editing a task detail
+- WHEN the user enters an estimate (e.g., "2h 30m" or "150 minutes")
+- THEN the system MUST store `estimatedDuration` in minutes on the task
+- AND the task card on the kanban board MUST display the estimate (e.g., "2h 30m")
+
+### Requirement: Log Time [MVP]
+The system MUST allow users to log time spent on a task.
+
+#### Scenario: Log a time entry
+- GIVEN a user is viewing a task detail
+- WHEN the user clicks "Log time" and enters duration, date, and optional description
+- THEN the system MUST create a TimeEntry object linked to the task
+- AND the task MUST display the total logged time (sum of all entries)
+- AND the logged time MUST appear in the user's timesheet
+
+#### Scenario: Multiple time entries per task
+- GIVEN a user has already logged 1h on a task on Monday
+- WHEN the user logs another 45 minutes on Tuesday
+- THEN the system MUST create a second TimeEntry for Tuesday
+- AND the task MUST show total logged time of 1h 45m
+
+#### Scenario: Edit a time entry
+- GIVEN a user has a time entry on a task
+- WHEN the user edits the entry's duration or description
+- THEN the system MUST update the entry
+- AND the task's total logged time MUST recalculate immediately
+
+#### Scenario: Delete a time entry
+- GIVEN a user has a time entry
+- WHEN the user deletes it
+- THEN the system MUST remove the entry
+- AND the task's total logged time MUST recalculate
+
+### Requirement: Personal Timesheet [MVP]
+The system MUST provide a timesheet view showing the current user's time entries grouped by date.
+
+#### Scenario: View my timesheet
+- GIVEN a user has logged time on multiple tasks
+- WHEN the user opens the Timesheet view
+- THEN the system MUST show all entries grouped by date (newest first)
+- AND each row MUST show: task title, project, duration, description
+- AND a daily total MUST be shown for each date group
+- AND a weekly total MUST be shown for the current view
+
+#### Scenario: Filter timesheet by date range
+- GIVEN the timesheet is open
+- WHEN the user selects a date range (e.g., "This week" or a custom range)
+- THEN the system MUST filter entries to the selected range
+- AND the total for the range MUST be displayed
+
+## User Stories
+
+- As a developer, I want to log the time I spent on a task so that the team has accurate capacity data
+- As a team member, I want to see my logged time in a weekly timesheet so that I can review my work patterns
+- As a project lead, I want to see estimated vs actual time per task so that I can improve future estimates
+- As a user, I want to add multiple time logs per task so that I can track time across multiple work sessions
+- As a team member, I want to see my total hours for the week so that I can track my workload
+
+## Acceptance Criteria
+
+- [ ] Time estimate can be set on any task (input accepts "1h 30m", "90m", "1.5h" formats)
+- [ ] Estimated duration is stored in minutes and displayed in human-readable format on task card and detail
+- [ ] "Log time" button is accessible from the task detail view
+- [ ] A time entry requires at minimum a duration and a date
+- [ ] Multiple time entries can be added to the same task
+- [ ] Total logged time is computed from all entries and displayed on the task
+- [ ] Logged time vs estimated time shows a progress indicator (e.g., "1h 30m / 3h")
+- [ ] Timesheet view shows all entries by the current user grouped by date
+- [ ] Timesheet shows daily totals and weekly total
+- [ ] Timesheet can be filtered by date range
+- [ ] Users can edit and delete their own time entries
+- [ ] Admins (V1) can view and export all users' time entries per project
+
+## Notes
+
+- Time granularity is minutes (integer). Avoids floating-point precision issues.
+- Timer (start/stop, auto-log) is a V1 feature. MVP is manual entry only.
+- Time export (CSV) is V1. Includes: task title, project, user, date, duration, description.
+- Project-level time report (V1): total estimated vs logged per task, aggregated per project.
+- Team timesheet (V1): admin view of all users' entries, exportable.
+- The `loggedDuration` field on Task is computed at read time (sum of linked TimeEntry objects), not stored.

-# Tasks — Admin Settings MVP
+# Tasks — Time Tracking MVP
 
-## Task 1: Backend — SettingsController admin endpoints
-**spec_ref**: admin-user-settings.md → Requirement: Admin Settings Page
-**files_likely_affected**: lib/Controller/SettingsController.php, appinfo/routes.php
+## Task 1: Backend — TimeEntry CRUD endpoints
+**spec_ref**: time-tracking.md → Requirement: Time Entry Logging
+**files_likely_affected**: lib/Controller/TimeEntryController.php (new), lib/Service/TimeEntryService.php (new), appinfo/routes.php
 **acceptance_criteria**:
-- [x] `GET /api/settings` returns current admin settings as JSON
-- [x] `POST /api/settings` accepts a JSON body and stores values via IAppConfig
-- [x] Settings include: `default_columns` (JSON string), `allow_project_creation` (string)
-- [x] Only admin users can write settings (middleware or annotation check)
-- [x] Returns 403 for non-admin write attempts
+- [ ] `POST /api/time-entries` creates a time entry (taskId, hours, date, description)
+- [ ] `GET /api/time-entries?taskId={id}` lists time entries for a task
+- [ ] `DELETE /api/time-entries/{id}` deletes a time entry (owner only)
+- [ ] Validation: hours > 0, date required, taskId must exist
+- [ ] Returns 403 for non-authenticated users
 
-## Task 2: Backend — SettingsService business logic

-**files_likely_affected**: src/views/settings/AdminRoot.vue, src/views/settings/Settings.vue
-**acceptance_criteria**:
-- [x] Admin settings page renders under Nextcloud Administration → Planix
-- [x] First section is CnVersionInfoCard showing app name and version
-- [x] Page uses CnSettingsSection for each logical group
-- [x] Loads current settings from `GET /api/settings` on mount
-
-## Task 4: Frontend — Default columns editor
-**spec_ref**: admin-user-settings.md → Scenario: Configure default columns
-**files_likely_affected**: src/views/settings/Settings.vue or new component
-**acceptance_criteria**:

-- [x] Admin can add, remove, and reorder column names
-- [x] Changes are saved via `POST /api/settings` on save button click
-- [x] Shows success/error feedback after save
-
-## Task 5: Frontend — OpenRegister initialization section
-**spec_ref**: admin-user-settings.md → Scenario: OpenRegister initialization
-**files_likely_affected**: src/views/settings/Settings.vue or new component
-**acceptance_criteria**:
-- [x] Shows whether the Planix register is initialized (green check / warning)
-- [x] If not initialized, shows "Initialize register" button
-- [x] Button triggers register initialization (calls backend endpoint)
-- [x] Shows loading state during initialization
-- [x] Shows success or error result after completion
+- [ ] TimeLog.vue shows list of time entries for the current task
+- [ ] Each entry shows: date, hours, description, delete button (if owner)
+- [ ] "Log time" form with hours input, date picker, description field
+- [ ] Form validates hours > 0 before submission
+- [ ] Empty state: "No time logged yet" with prompt to log first entry

Subject: [PATCH 3/8] feat: add frontend time log component and task detail
 view

- TimeLog.vue: displays time entries for a task with log form and delete
- TaskDetail.vue: task detail view with breadcrumb, meta, and TimeLog
- timeEntries.js: Pinia store for time entry CRUD via OpenRegister
- Router: added /tasks/:taskId route for task detail

Subject: [PATCH 6/8] fix iteration 1: security hardening and quality fixes
 from code review

- [F-02/CRITICAL] Add @NoCSRFRequired to create(), index(), destroy() so browser
  AJAX calls are not blocked by Nextcloud CSRF protection; add UUID format validation
  in index() and destroy() (return 400 for malformed identifiers)
- [F-01/CRITICAL] Rewrite timeEntries.js store to call TimeEntryController REST
  endpoints via @nextcloud/axios instead of OpenRegister objectStore directly;
  server-side validation, task-existence checks, and owner-only delete are now
  exercised on every request; client no longer sets the user field
- [F-05/SEC-002/WARNING] Add ISO 8601 date format validation and UUID format
  validation for taskId in TimeEntryService::validateTimeEntryData()
- [SEC-001/WARNING] Add project membership guard to listTimeEntries(): fetch the
  parent task, resolve its project, and verify the requesting user is in
  project.members before returning entries (IDOR fix)
- [F-03/WARNING] Fix 16 PHPCS violations in TimeEntryServiceTest.php: add named
  params to all expectException()/expectExceptionMessage() calls, reformat
  multi-line createTimeEntry() call bodies; add tests for new UUID and date
  format validations
- [F-04/WARNING] Add testDestroyReturnsNotFoundWhenEntryDoesNotExist() and
  testDestroyReturnsBadRequestForInvalidUuid() to TimeEntryControllerTest;
  update existing destroy tests to use valid UUID strings
- [F-06/WARNING] Add window.confirm() guard in TimeLog.vue deleteEntry() to
  prevent accidental data loss on mis-click

Subject: [PATCH 7/8] fix iteration 2: close IDOR gaps, fix field name
 mismatch, harden CSRF
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- F-001 (CRITICAL): TimeLog.vue submitEntry — change `task:` to `taskId:` so
  the frontend payload matches the field name expected by
  TimeEntryService::validateTimeEntryData(). Every create call was returning 400.
- F-004 (WARNING): TimeLog.vue submitEntry — gate form reset on `if (entry)`
  so user input is preserved when createEntry() returns null on failure.
- SEC-004 (WARNING): TimeEntryController — remove @NoCSRFRequired from
  create() and destroy(); @nextcloud/axios includes the CSRF token automatically,
  so state-mutating endpoints must enforce CSRF verification.
- SEC-001/F-002/SEC-002 (CRITICAL/WARNING): TimeEntryService — extract
  assertProjectMembership() helper that fails closed: denies when task has no
  project, when the project record is missing, and when the user is not in the
  members array (replaces the old fail-open empty($members) guard).
- F-003/SEC-003 (WARNING): TimeEntryService::createTimeEntry() — call
  assertProjectMembership() before saving, closing the write-side IDOR gap.
