60e05e0815 refactor(currency)!: rename major/minor to base/subunit currency terminology 
Complete terminology migration from confusing "major/minor" to clearer
"base/subunit" currency naming throughout entire codebase, translations,
documentation, tests, and services.

BREAKING CHANGES:

1. **Service API Parameters Renamed**:
   - `get_chartdata`: `minor_currency` → `subunit_currency`
   - `get_apexcharts_yaml`: Updated service_data references from
     `minor_currency: true` to `subunit_currency: true`
   - All automations/scripts using these parameters MUST be updated

2. **Configuration Option Key Changed**:
   - Config entry option: Display mode setting now uses new terminology
   - Internal key: `currency_display_mode` values remain "base"/"subunit"
   - User-facing labels updated in all 5 languages (de, en, nb, nl, sv)

3. **Sensor Entity Key Renamed**:
   - `current_interval_price_major` → `current_interval_price_base`
   - Entity ID changes: `sensor.tibber_home_current_interval_price_major`
     → `sensor.tibber_home_current_interval_price_base`
   - Energy Dashboard configurations MUST update entity references

4. **Function Signatures Changed**:
   - `format_price_unit_major()` → `format_price_unit_base()`
   - `format_price_unit_minor()` → `format_price_unit_subunit()`
   - `get_price_value()`: Parameter `in_euro` deprecated in favor of
     `config_entry` (backward compatible for now)

5. **Translation Keys Renamed**:
   - All language files: Sensor translation key
     `current_interval_price_major` → `current_interval_price_base`
   - Service parameter descriptions updated in all languages
   - Selector options updated: Display mode dropdown values

**Coordinator/Period Calculation**:
- coordinator/periods.py: Added config_entry parameter to
  calculate_periods_with_relaxation() calls (2 locations)

Migration Guide:

1. **Update Service Calls in Automations/Scripts**:
   \`\`\`yaml
   # Before:
   service: tibber_prices.get_chartdata
   data:
     minor_currency: true

   # After:
   service: tibber_prices.get_chartdata
   data:
     subunit_currency: true
   \`\`\`

2. **Update Energy Dashboard Configuration**:
   - Settings → Dashboards → Energy
   - Replace sensor entity:
     `sensor.tibber_home_current_interval_price_major` →
     `sensor.tibber_home_current_interval_price_base`

3. **Review Integration Configuration**:
   - Settings → Devices & Services → Tibber Prices → Configure
   - New "Currency Display Settings" step added
   - Default mode depends on currency (EUR → subunit, Scandinavian → base)

Rationale:

The "major/minor" terminology was confusing and didn't clearly communicate:
- **Major** → Unclear if this means "primary" or "large value"
- **Minor** → Easily confused with "less important" rather than "smaller unit"

New terminology is precise and self-explanatory:
- **Base currency** → Standard ISO currency (€, kr, $, £)
- **Subunit currency** → Fractional unit (ct, øre, ¢, p)

This aligns with:
- International terminology (ISO 4217 standard)
- Banking/financial industry conventions
- User expectations from payment processing systems

Impact: Aligns currency terminology with international standards. Users must
update service calls, automations, and Energy Dashboard configuration after
upgrade.

c2b9908e69 refactor(naming): complete class naming convention alignment 
Renamed 25 public classes + 1 Enum to include TibberPrices prefix
following Home Assistant integration naming standards.

All classes now follow pattern: TibberPrices{SemanticPurpose}
No package hierarchy in names (import path is namespace).

Key changes:
- Coordinator module: DataFetcher, DataTransformer, ListenerManager,
  PeriodCalculator, TimeService (203 usages), CacheData
- Config flow: CannotConnectError, InvalidAuthError
- Entity utils: IconContext
- Sensor calculators: BaseCalculator + 8 subclasses
- Period handlers: 5 NamedTuples (PeriodConfig, PeriodData,
  PeriodStatistics, ThresholdConfig, IntervalCriteria)
- Period handlers: SpikeCandidateContext (dataclass → NamedTuple)
- API: QueryType Enum

Documentation updates:
- AGENTS.md: Added Pyright code generation guidelines
- planning/class-naming-refactoring-plan.md: Complete execution log

Quality metrics:
- 0 Pyright errors (strict type checking)
- 0 Ruff errors (linting + formatting)
- All hassfest checks passed
- 79 files validated

Impact: Aligns with HA Core standards (TibberDataCoordinator pattern).
No user-facing changes - internal refactor only.

625bc222ca refactor(coordinator): centralize time operations through TimeService 
Introduce TimeService as single source of truth for all datetime operations,
replacing direct dt_util calls throughout the codebase. This establishes
consistent time context across update cycles and enables future time-travel
testing capability.

Core changes:
- NEW: coordinator/time_service.py with timezone-aware datetime API
- Coordinator now creates TimeService per update cycle, passes to calculators
- Timer callbacks (#2, #3) inject TimeService into entity update flow
- All sensor calculators receive TimeService via coordinator reference
- Attribute builders accept time parameter for timestamp calculations

Key patterns replaced:
- dt_util.now() → time.now() (single reference time per cycle)
- dt_util.parse_datetime() + as_local() → time.get_interval_time()
- Manual interval arithmetic → time.get_interval_offset_time()
- Manual day boundaries → time.get_day_boundaries()
- round_to_nearest_quarter_hour() → time.round_to_nearest_quarter()

Import cleanup:
- Removed dt_util imports from ~30 files (calculators, attributes, utils)
- Restricted dt_util to 3 modules: time_service.py (operations), api/client.py
  (rate limiting), entity_utils/icons.py (cosmetic updates)
- datetime/timedelta only for TYPE_CHECKING (type hints) or duration arithmetic

Interval resolution abstraction:
- Removed hardcoded MINUTES_PER_INTERVAL constant from 10+ files
- New methods: time.minutes_to_intervals(), time.get_interval_duration()
- Supports future 60-minute resolution (legacy data) via TimeService config

Timezone correctness:
- API timestamps (startsAt) already localized by data transformation
- TimeService operations preserve HA user timezone throughout
- DST transitions handled via get_expected_intervals_for_day() (future use)

Timestamp ordering preserved:
- Attribute builders generate default timestamp (rounded quarter)
- Sensors override when needed (next interval, daily midnight, etc.)
- Platform ensures timestamp stays FIRST in attribute dict

Timer integration:
- Timer #2 (quarter-hour): Creates TimeService, calls _handle_time_sensitive_update(time)
- Timer #3 (30-second): Creates TimeService, calls _handle_minute_update(time)
- Consistent time reference for all entities in same update batch

Time-travel readiness:
- TimeService.with_reference_time() enables time injection (not yet used)
- All calculations use time.now() → easy to simulate past/future states
- Foundation for debugging period calculations with historical data

Impact: Eliminates timestamp drift within update cycles (previously 60+ independent
dt_util.now() calls could differ by milliseconds). Establishes architecture for
time-based testing and debugging features.

4876a2cc29 refactor(entity_utils): extract shared helpers from sensor platform 
Created entity_utils/helpers.py with platform-agnostic utility functions:
- get_price_value(): Price unit conversion (major/minor currency)
- translate_level(): Price level translation
- translate_rating_level(): Rating level translation
- find_rolling_hour_center_index(): Rolling hour window calculations

These functions moved from sensor/helpers.py as they are used by both
sensor and binary_sensor platforms. Remaining sensor/helpers.py now
contains only sensor-specific helpers (aggregate_price_data, etc.).

Updated imports:
- sensor/core.py: Import from entity_utils instead of sensor.helpers
- entity_utils/icons.py: Fixed find_rolling_hour_center_index import
- binary_sensor platforms: Can now use shared helpers

Added clear docstrings explaining:
- entity_utils/helpers.py: Platform-agnostic utilities
- sensor/helpers.py: Sensor-specific aggregation functions

Impact: Better code reuse, clearer responsibility boundaries between
platform-specific and shared utilities.
