imports, source IDs, directory names, docs, and configs.

* feat(backend): add LLM-powered feed enhancement
Add enhancement harness that fills feed item slots and
generates synthetic items via OpenRouter.
- LLM client with 30s timeout, reusable SDK instance
- Prompt builder with mini calendar and week overview
- arktype schema validation + JSON Schema for structured output
- Pure merge function with clock injection
- Defensive fallback in feed endpoint on enhancement failure
- Skips LLM call when no unfilled slots or no API key
Co-authored-by: Ona <no-reply@ona.com>
* refactor: move feed enhancement into UserSession
Move enhancement logic from HTTP handler into UserSession so the
transport layer has no knowledge of enhancement. UserSession.feed()
handles refresh, enhancement, and caching in one place.
- UserSession subscribes to engine updates and re-enhances eagerly
- Enhancement cache tracks source identity to prevent stale results
- UserSessionManager accepts config object with optional enhancer
- HTTP handler simplified to just call session.feed()

* test: add schema sync tests for arktype/JSON Schema drift
Validates reference payloads against both the arktype schema
(parseEnhancementResult) and the OpenRouter JSON Schema structure.
Catches field additions/removals or type changes in either schema.

Adds three LLM-fillable slots to every CalDav feed item:
insight, preparation, and crossSource. Slot prompts are
stored in separate .txt files under src/prompts/ with
few-shot examples to steer the LLM away from restating
event details.

The iCal parser returned master VEVENT components with their
original start dates instead of expanding recurrences. Events
from months ago appeared in today's feed.
parseICalEvents now accepts an optional timeRange. When set,
recurring events are expanded via ical.js iterator and only
occurrences overlapping the range are returned. Exception
overrides (RECURRENCE-ID) are applied during expansion.

Add LLM-fillable insight slot to weather-current feed items.
Prompt lives in a separate .txt file for easy iteration.
Also adds interactive CLI script (scripts/query.ts) for
querying WeatherKit with credential caching and JSON output.

Rule-based feed post-processor that reranks items
by time period, day type, and calendar proximity.

Context keys are now tuples instead of strings, inspired by
React Query's query keys. This prevents context collisions
when multiple instances of the same source type are registered.
Sources write to structured keys like
["aris.google-calendar", "nextEvent", { account: "work" }]
and consumers can query by prefix via context.find().

Replace hardcoded "tfl-alert" string with a
TflFeedItemType const object, matching the pattern

* feat: add boost directive to FeedEnhancement
Post-processors can now return a boost map (item ID -> score)
to promote or demote items in the feed ordering. Scores from
multiple processors are summed and clamped to [-1, 1].

Post-processors now receive Context as their 2nd parameter,
allowing them to use contextual data (time, location, etc.)
when producing enhancements.

* feat: add generic CalDAV calendar data source
Add @aris/source-caldav package that fetches calendar events from any
CalDAV server via tsdav + ical.js.
- Supports Basic auth and OAuth via explicit authMethod discriminant
- serverUrl provided at construction time, not hardcoded
- Optional timeZone for correct local day boundaries
- Credentials cleared from memory after client login
- Failed calendar fetches logged, not silently dropped
- Login promise cached with retry on failure

* fix: deduplicate concurrent fetchEvents calls
Co-authored-by: Ona <no-reply@ona.com>
* fix: timezone-aware signals, low-priority cancelled events
- computeSignals uses startOfDay(timeZone) for 'later today' boundary
- Cancelled events get urgency 0.1, excluded from context inProgress/nextEvent

* feat: add post-processor pipeline to FeedEngine
Add FeedPostProcessor type and FeedEnhancement interface.
Post-processors run after item collection on all update
paths (refresh, reactive context, reactive items).
Pipeline is chained — each processor sees items as modified
by the previous one. Enhancement merging handles additional
items, suppression, and grouped items. Throwing processors
are caught and recorded in FeedResult.errors.

* docs: document intentional TItems cast in post-processor merge

* fix: filter stale item IDs from groups after pipeline
Groups accumulated during the pipeline can reference items
that a later processor suppressed. The engine now strips
stale IDs and drops empty groups before returning.

* feat: replace FeedItem.priority with signals
Remove priority field from FeedItem and engine-level sorting.
Add FeedItemSignals with urgency and timeRelevance fields.
Update all source packages to emit signals instead of priority.
Ranking is now the post-processing layer's responsibility.
Urgency values are unchanged from the old priority values.

Add lastFeed() method that returns cached FeedResult within
a configurable TTL (default 5 min). refresh() always fetches
fresh data and updates the cache. Periodic auto-refresh via
recursive setTimeout when engine is started. Reactive updates
reset the timer to avoid redundant fetches.

Add listActions() and executeAction() to FeedSource for write
operations back to external services. Actions use arktype schemas
for input validation via StandardSchemaV1.
- ActionDefinition type with optional input schema
- FeedEngine routes actions with existence and ID validation
- Source IDs use reverse-domain format (aris.location, aris.tfl)
- LocationSource: update-location action with schema validation
- TflSource: set-lines-of-interest action with lineId validation
- No-op implementations for sources without actions

Sources that cannot provide context now return null
instead of omitting the method. The engine checks the
return value rather than method existence.

FeedEngine calls fetchContext then fetchItems with the same
context. Cache events by context.time reference to avoid
duplicate CalDAV round-trips.

Add @aris/source-apple-calendar for fetching iCloud
calendar events via CalDAV using tsdav and ical.js.
- CalendarSource implements FeedSource with fetchItems
and fetchContext for downstream context
- CalendarCredentialProvider interface for token injection
- CalendarDAVClient interface for testability
- iCal parser extracts full event data including
attendees, alarms, organizer, and recurrence
- Priority based on event proximity to current time

Manages per-user TflSource instances with individual line
configuration. Implements FeedSourceProvider so it can be
wired into FeedEngineService.
Adds TflSource.setLines() so line config can be mutated
in place, keeping engine references valid.
Also exports ITflApi from @aris/source-tfl for testability.

Migrates TFL package from old DataSource interface to new FeedSource
interface for use with FeedEngine.
Changes:
- Rename package from @aris/data-source-tfl to @aris/source-tfl
- Replace TflDataSource class with TflSource implementing FeedSource
- Add dependency on @aris/source-location for LocationKey
- Use normalized priority values (0-1) instead of arbitrary numbers
- Update tests for FeedSource interface
- Update README.md with new package name

Introduces FeedEngine that consumes FeedSource instances and manages
the dependency graph for context flow and item collection.
- Validates dependency graph (missing deps, circular references)
- Topologically sorts sources for execution order
- Runs fetchContext() in dependency order, accumulating context
- Runs fetchItems() on all sources with final context
- Supports reactive updates via onContextUpdate/onItemsUpdate
- Graceful error handling (continues after source failures)
Marks DataSource, ContextProvider, ContextBridge, Reconciler, and
FeedController as deprecated in favor of FeedSource + FeedEngine.

Implements FeedSource for WeatherKit API. Depends on location source,
provides weather context for downstream sources, and produces weather
feed items.

Implements FeedSource interface. Accepts external location pushes,
provides context to downstream sources, does not produce feed items.
Supports configurable history size.

Unifies DataSource and ContextProvider into a single interface that
forms a dependency graph. Sources declare dependencies on other sources
and can provide context, feed items, or both.
Deprecates DataSource, ContextProvider, and ContextBridge.
