-# weatherfeeder API (Wire Contract)
+# Event Wire Contract
 
-This document defines the stable, consumer-facing JSON contract emitted by weatherfeeder sinks.
-
-weatherfeeder emits **events** encoded as JSON. Each event has:
-- an **envelope** (metadata + schema identifier), and
-- a **payload** whose shape is determined by `schema`.
-
-Downstream consumers should:
-1. parse the event envelope,
-2. switch on `schema`, then
-3. decode `payload` into the matching schema.
-
----
-
-## Event envelope
-
-All events are JSON objects with these fields:
-
-| Field | Type | Required | Notes |
-|---|---:|:---:|---|
-| `id` | string | yes | Stable event identifier. Treat as opaque. |
-| `schema` | string | yes | Schema identifier (e.g. `weather.observation.v1`). |
-| `source` | string | yes | Provider/source identifier (stable within configuration). |
-| `effectiveAt` | string (timestamp) | yes | RFC3339Nano timestamp indicating when this event is effective. |
-| `payload` | object | yes | Schema-specific payload (see below). |
-
-### Timestamp format
-
-All timestamps are encoded as JSON strings using Go’s `time.Time` JSON encoding (RFC3339Nano).
-
-Examples:
-- `"2026-01-17T14:27:00Z"`
-- `"2026-01-17T08:27:00-06:00"`
-
----
-
-## Canonical schemas
-
-weatherfeeder emits four canonical domain schemas:
-
-- `weather.observation.v1`
-- `weather.forecast.v1`
-- `weather.forecast_discussion.v1`
-- `weather.alert.v1`
-
-Each payload is described below using the JSON field names as the contract.
-
-### Raw upstream schemas
-
-weatherfeeder sources also emit provider-specific raw schemas before normalization.
-For this feature, the raw source schema is:
-
-- `raw.nws.forecast_discussion.v1`
-  - payload type: string
-  - payload contents: exact fetched HTML response body
-
----
-
-## Shared Conventions
-
-- Timestamps are JSON strings in RFC3339Nano format.
-- Optional fields are omitted when unknown (`omitempty` behavior).
-- Numeric measurements are normalized to metric units:
-  - `*C` = Celsius
-  - `*Kmh` = kilometers/hour
-  - `*Pa` = Pascals
-  - `*Meters` = meters
-  - `*Mm` = millimeters
-  - `*Percent` = percent (0-100)
-- `conditionCode` is a WMO weather interpretation code (`int`).
-  - Unknown/unmappable is `-1`.
-  - Downstream consumers should treat unknown codes as “unknown conditions” rather than failing decoding.
-- For readability and stability, weatherfeeder rounds floating-point values in canonical payloads to
-**4 digits after the decimal** during normalization.

-## Compatibility rules
-
-- Consumers **must** ignore unknown fields.

 # weatherfeeder
 
-weatherfeeder is a small daemon that polls weather observations, forecasts, and alerts from multiple upstream
-providers, normalizes them into a provider-independent format, and emits them to a sink.
+`weatherfeeder` is a config-driven daemon that polls weather providers, normalizes
+provider-specific responses into canonical weather events, and routes those
+events to configured sinks.
 
-Today, the only implemented sink is `stdout`, which prints JSON-encoded events.
+It currently supports NWS observations, alerts, hourly forecasts, narrative
+forecasts, forecast discussions, and weather stories; Open-Meteo observations
+and hourly forecasts; and OpenWeather observations. Implemented sinks are
+stdout, NATS, and Postgres.
 
-## What weatherfeeder emits
+## Quickstart
 
-weatherfeeder emits **feed events** encoded as JSON. Each event includes a schema identifier and a payload.
-Downstream consumers should key off the `schema` value and decode the `payload` accordingly.
+Run the checked-in sample config:
 
-Canonical domain schemas emitted after normalization:
+```sh
+cd cmd/weatherfeeder
+go run .
+```
 
-- `weather.observation.v1` → `WeatherObservation`
-- `weather.forecast.v1` → `WeatherForecastRun`
-- `weather.forecast_discussion.v1` → `WeatherForecastDiscussion`
-- `weather.alert.v1` → `WeatherAlertRun`
+The sample config at `cmd/weatherfeeder/config.yml` is load-tested and can be
+used as a starting point. The executable always reads `config.yml` from its
+current working directory.
 
-For the complete wire contract (event envelope + payload schemas, fields, units, and compatibility rules), see:
+## Documentation
 
-- **API.md**
-
-## Upstream providers (current MVP)
-
-- NWS: observations, hourly forecasts, narrative forecasts, forecast discussions, alerts
-- Open-Meteo: observations, hourly forecasts
-- OpenWeather: observations
-
-## Versioning & compatibility
-
-The JSON field names on canonical payload types are treated as part of the wire contract.
-Additive changes are preferred. Renames/removals require a schema version bump.
-

+# CLI Reference
+
+## Shortest Useful Command
+
+Run `weatherfeeder` from a directory containing `config.yml`:
+
+```sh
+cd cmd/weatherfeeder
+go run .
+```
+
+When using a built binary:
+
+```sh
+./weatherfeeder
+```
+
+## Command Overview
+
+`weatherfeeder` starts a long-running polling daemon. On startup it:
+
+1. reads `config.yml` from the current working directory;
+2. builds configured sources, sinks, and routes;
+3. starts polling sources on their configured intervals;
+4. normalizes and deduplicates events;
+5. dispatches matching events to configured sinks.
+
+The command logs startup, runtime, and shutdown messages to stderr using the Go
+standard logger.
+
+## Flags
+
+There are currently no CLI flags, subcommands, or environment-variable based
+configuration controls.
+
+The config path is fixed at `config.yml` relative to the process current working
+directory. To run with a different config, change the working directory or place
+the desired file at that path.
+
+## Common Workflows
+
+Run the checked-in sample config:
+
+```sh
+cd cmd/weatherfeeder
+go run .
+```
+
+Maintained copyable configs are available under [`examples/`](../examples/).
+
+Build and run a local binary:
+
+```sh
+go build -o weatherfeeder ./cmd/weatherfeeder
+cp cmd/weatherfeeder/config.yml .
+./weatherfeeder
+```
+
+Run in the project container image with a mounted config:
+
+```sh
+docker run --rm -v "$PWD/config.yml:/weatherfeeder/config.yml:ro" weatherfeeder
+```
+
+The Docker image sets `/weatherfeeder` as the working directory, so the mounted
+file must appear at `/weatherfeeder/config.yml`.
+
+## Shutdown
+
+Stop the daemon with `Ctrl-C` or `SIGTERM`. The process uses context-aware
+shutdown for scheduler, dispatcher, processors, sources, and sinks, then logs
+`shutdown complete`.

+# Configuration Reference
+
+## Config File
+
+`weatherfeeder` reads exactly one YAML file named `config.yml` from the current
+working directory. There is no config path flag and no search path.
+
+YAML decoding is strict for config struct fields: misspelled fields such as
+`sources[].drviver` fail startup. Driver-specific `params` maps are validated by
+the source or sink constructor that consumes them.
+
+The top-level file contains:
+
+```yaml
+sources:
+  - name: NWSObservationKSTL
+    mode: poll
+    driver: nws_observation
+    every: 10m
+    kinds: ["observation"]
+    params:
+      url: "https://api.weather.gov/stations/KSTL/observations/latest"
+      user_agent: "Example weatherfeeder operator (ops@example.com)"
+
+sinks:
+  - name: stdout
+    driver: stdout
+    params: {}
+
+routes:
+  - sink: stdout
+    kinds: ["observation"]
+```
+
+`sources` and `sinks` must each contain at least one entry. `routes` is optional.
+When `routes` is omitted, every configured sink receives every event kind.
+Maintained copyable configs are available under [`examples/`](../examples/).
+
+## Production-Oriented Shape
+
+A typical deployment uses multiple polling sources and sends the same canonical
+event stream to a broker or database:
+
+```yaml
+sources:
+  - name: NWSAlertsLocal
+    mode: poll
+    driver: nws_alerts

+
+## Top-Level Fields
+
+| Field | Required | Description |
+|---|:---:|---|
+| `sources` | yes | List of configured input sources. |
+| `sinks` | yes | List of configured output sinks. |
+| `routes` | no | List of sink routing rules. If omitted, all sinks receive all kinds. |
+
+## Source Fields
+
+| Field | Required | Description |
+|---|:---:|---|
+| `name` | yes | Unique source name. Used as the event source identifier. |
+| `driver` | yes | Source driver name. |
+| `mode` | no | `poll`, `stream`, or omitted for auto. Current weatherfeeder drivers are polling drivers. |
+| `every` | yes | Poll interval for current weatherfeeder source drivers. |
+| `kinds` | no | Expected event kinds. If present, startup verifies they match the source driver. |
+| `params` | driver-specific | Driver parameters. Current source drivers require HTTP params. |
+
+Current event kinds are `observation`, `forecast`, `forecast_discussion`,
+`weather_story`, and `alert`.
+
+## Source Drivers
+
+| Driver | Kind | Upstream product |
+|---|---|---|
+| `nws_observation` | `observation` | NWS station latest observation. |
+| `nws_alerts` | `alert` | NWS alerts collection. |
+| `nws_forecast_hourly` | `forecast` | NWS hourly gridpoint forecast. |
+| `nws_forecast_narrative` | `forecast` | NWS narrative gridpoint forecast. |
+| `nws_forecast_discussion` | `forecast_discussion` | NWS forecast discussion HTML product. |
+| `nws_weatherstories` | `weather_story` | NWS office weather stories. |
+| `openmeteo_observation` | `observation` | Open-Meteo current conditions. |
+| `openmeteo_forecast` | `forecast` | Open-Meteo hourly forecast. |
+| `openweather_observation` | `observation` | OpenWeather current weather. |
+
+## HTTP Source Params
+
+All current source drivers use the shared HTTP polling helper.
+
+| Param | Required | Description |
+|---|:---:|---|
+| `url` | yes | Full upstream request URL. `URL` is also accepted by the helper. |
+| `user_agent` | yes | User-Agent sent to the upstream provider. `userAgent` is also accepted by the helper. |
+| `conditional` | no | Boolean. Defaults to `true`; enables ETag and Last-Modified conditional requests. |
+| `http_timeout` | no | Positive duration for the HTTP client timeout. |
+| `http_response_body_limit_bytes` | no | Positive integer response body limit in bytes. |
+
+When `conditional` is enabled and the upstream returns `304 Not Modified`, the
+source emits no events for that poll.
+
+OpenWeather observation URLs must include `units=metric`. Startup fails if the
+URL omits it or sets another unit system.
+
+## Sink Fields
+
+| Field | Required | Description |
+|---|:---:|---|
+| `name` | yes | Unique sink name. Routes refer to this value. |
+| `driver` | yes | Sink driver name. |
+| `params` | driver-specific | Sink parameters. |
+
+## Sink Drivers
+
+### `stdout`
+
+Prints each event as JSON to stdout.
+
+```yaml
+sinks:
+  - name: stdout
+    driver: stdout
+    params: {}
+```
+
+### `nats`
+
+Publishes each event as JSON to a NATS subject.
+
+| Param | Required | Description |
+|---|:---:|---|
+| `url` | yes | NATS server URL, such as `nats://localhost:4222`. |
+| `subject` | yes | Subject to publish events to. |
+
+### `postgres`
+
+Writes supported canonical weather events to Postgres using weatherfeeder's
+registered schema mapping. The table contract is documented in
+[Postgres integration](integrations/postgres.md).
+
+| Param | Required | Description |
+|---|:---:|---|
+| `uri` | yes | PostgreSQL connection URI. |
+| `username` | yes | Database username. |
+| `password` | yes | Database password. |
+| `prune` | no | Retention window. If set, rows older than the window are pruned on each write transaction. |
+
+`prune` accepts Go duration strings such as `72h`, plus day and week suffixes
+such as `3d` and `2w`.
+
+## Routes
+
+Routes connect event kinds to sinks:
+
+```yaml
+routes:
+  - sink: stdout
+    kinds: ["observation", "alert"]
+```
+
+| Field | Required | Description |
+|---|:---:|---|
+| `sink` | yes | Name of a configured sink. |
+| `kinds` | no | Event kinds to send to that sink. Omit or use an empty list to match all kinds. |

+Route `kinds` values are trimmed and lowercased by the dispatcher. Blank entries
+are rejected.
+
+## Duration Formats
+
+Top-level source `every` accepts:
+
+- Go duration strings such as `30s`, `10m`, or `1h`;
+- integer values, interpreted as minutes;
+- numeric strings such as `"15"`, also interpreted as minutes.
+
+HTTP param durations such as `http_timeout` accept Go duration strings. Numeric
+values and numeric strings are interpreted as seconds.
+
+Postgres `prune` must be a string duration.
+
+## Secrets
+
+The config file is read directly from disk and has no built-in secret expansion.
+Keep real credentials out of repository-tracked configs. Use deployment tooling
+to render `config.yml` with the needed secret values before starting the daemon.
+
+## Maintained Examples

+# Event Wire Contract
+
+This document is the canonical JSON contract for events emitted by
+`weatherfeeder` JSON sinks, including stdout and NATS. Postgres stores the same
+event envelope fields in parent table columns; see
+[Postgres integration](postgres.md).
+
+Downstream consumers should read the envelope, switch on `schema`, and decode
+`payload` according to that schema.
+
+## Envelope
+
+Every emitted event is a JSON object with these fields:
+
+| Field | Type | Required | Notes |
+|---|---|:---:|---|
+| `id` | string | yes | Stable event identifier. Treat as opaque. |
+| `kind` | string | yes | Routing kind, such as `observation` or `alert`. |
+| `source` | string | yes | Configured source name. |
+| `emitted_at` | timestamp | yes | When the daemon emitted the event. |
+| `effective_at` | timestamp | no | Timestamp the payload is about, when known. |
+| `schema` | string | no | Schema identifier. Weatherfeeder sources and normalizers set this. |
+| `payload` | object, array, string, or scalar | yes | Schema-specific payload. |
+
+Timestamps are JSON strings using Go `time.Time` JSON encoding, which is
+RFC3339Nano-compatible. Weatherfeeder normalizers use UTC timestamps for
+canonical payloads.
+
+## Kinds And Schemas
+
+Canonical schemas emitted after normalization:
+
+| Kind | Schema | Payload |
+|---|---|---|
+| `observation` | `weather.observation.v1` | `WeatherObservation` |
+| `forecast` | `weather.forecast.v1` | `WeatherForecastRun` |
+| `forecast_discussion` | `weather.forecast_discussion.v1` | `WeatherForecastDiscussion` |
+| `weather_story` | `weather.weather_story.v1` | `WeatherStoryRun` |
+| `alert` | `weather.alert.v1` | `WeatherAlertRun` |
+
+Raw upstream schemas emitted by current sources:
+
+| Kind | Schema | Payload |
+|---|---|---|
+| `observation` | `raw.nws.observation.v1` | NWS observation JSON |
+| `observation` | `raw.openmeteo.current.v1` | Open-Meteo current JSON |
+| `observation` | `raw.openweather.current.v1` | OpenWeather current JSON |
+| `forecast` | `raw.nws.hourly.forecast.v1` | NWS hourly forecast JSON |
+| `forecast` | `raw.nws.narrative.forecast.v1` | NWS narrative forecast JSON |
+| `forecast_discussion` | `raw.nws.forecast_discussion.v1` | NWS forecast discussion HTML string |
+| `weather_story` | `raw.nws.weatherstories.v1` | NWS weather stories JSON |
+| `forecast` | `raw.openmeteo.hourly.forecast.v1` | Open-Meteo hourly forecast JSON |
+| `alert` | `raw.nws.alerts.v1` | NWS alerts JSON |
+
+`standards.SchemaRawOpenWeatherHourlyForecastV1` exists in code, but no current
+registered source emits it.
+
+## Shared Conventions
+
+- Canonical numeric measurements use metric units.
+- Floating-point values in canonical payloads are rounded to 4 digits after the
+  decimal point during normalization.
+- Optional fields use JSON `omitempty`; absent fields should be treated as
+  unknown.
+- `conditionCode` is a WMO weather interpretation code. Unknown observation
+  conditions use `-1`. Forecast period `conditionCode` is optional.
+- Additive fields are compatible within a schema version. Removing, renaming, or
+  changing the meaning of a field requires a new schema identifier.

+# NWS Integration Notes
+
+## Purpose
+
+This document describes the NWS products that `weatherfeeder` currently polls
+and normalizes. It is for developers and operators maintaining NWS source URLs,
+normalizers, fixtures, and tests.
+
+General config syntax belongs in [configuration](../config.md). Emitted JSON
+events are documented in [event wire contract](events.md).
+
+## Implemented Drivers
+
+| Driver | Kind | Raw schema | Canonical schema |
+| --- | --- | --- | --- |
+| `nws_observation` | `observation` | `raw.nws.observation.v1` | `weather.observation.v1` |
+| `nws_alerts` | `alert` | `raw.nws.alerts.v1` | `weather.alert.v1` |
+| `nws_forecast_hourly` | `forecast` | `raw.nws.hourly.forecast.v1` | `weather.forecast.v1` |
+| `nws_forecast_narrative` | `forecast` | `raw.nws.narrative.forecast.v1` | `weather.forecast.v1` |
+| `nws_forecast_discussion` | `forecast_discussion` | `raw.nws.forecast_discussion.v1` | `weather.forecast_discussion.v1` |
+| `nws_weatherstories` | `weather_story` | `raw.nws.weatherstories.v1` | `weather.weather_story.v1` |
+
+## Config Requirements
+
+All NWS drivers require HTTP source params:
+
+- `url`
+- `user_agent`
+
+The shared HTTP helper also accepts `conditional`, `http_timeout`, and
+`http_response_body_limit_bytes`. Conditional requests are enabled by default;
+an upstream `304 Not Modified` response emits no event for that poll.
+
+NWS expects a descriptive `User-Agent`. Do not use anonymous or placeholder
+contact values in production configs.
+
+## Upstream Shapes Used
+
+`nws_observation` expects the latest station observation GeoJSON shape. The
+normalizer uses fields under `properties` such as `stationId`, `stationName`,
+`timestamp`, `textDescription`, measured values, `presentWeather`, and
+`cloudLayers`, plus point geometry for day/night inference.
+
+`nws_alerts` expects an alerts FeatureCollection. The normalizer uses the
+collection `updated` timestamp, `title`, each feature ID, alert classification
+fields, narrative fields, timing fields, sender fields, and references.
+
+`nws_forecast_hourly` and `nws_forecast_narrative` expect gridpoint forecast
+GeoJSON with `properties.generatedAt`, `properties.updateTime`, elevation,
+polygon geometry, and ordered `periods`.
+
+`nws_forecast_discussion` expects an HTML page containing the discussion text in
+a `<pre>` block. The provider helper extracts office identity, product, issue
+time, update time, key messages, and short/long term sections.
+
+`nws_weatherstories` expects a JSON response with a `stories` array. The
+normalizer uses office ID, start/end/update times, title, description, alt text,
+priority, order, and download URL.
+
+## Accept Headers
+
+NWS JSON sources request:
+
+```text
+application/geo+json, application/json
+```
+
+The forecast discussion source requests:
+
+```text
+text/html, application/xhtml+xml
+```
+
+## Effective Time
+
+Source events set `effective_at` from the best metadata available:
+
+- observations: `properties.timestamp`;
+- alerts: collection `updated`, otherwise latest per-alert timestamp;
+- hourly and narrative forecasts: `properties.generatedAt`, otherwise update
+  time;
+- forecast discussions: parsed issue time;
+- weather stories: latest story update time, otherwise latest story start time.
+
+Normalizers use canonical payload time as the normalized event effective time.
+Alerts and weather stories fall back to the incoming event envelope when the
+payload does not provide a better snapshot time.
+
+## Mapping Notes
+
+Observations preserve raw `presentWeather` fragments and infer WMO condition
+codes from METAR phenomena, provider text, and cloud-layer fallback. Sea-level
+pressure is preferred over barometric pressure when present.
+
+Hourly forecasts infer WMO condition codes from `shortForecast` and icon tokens.
+Narrative forecasts preserve text but intentionally leave period condition codes
+unset. Forecast temperatures are converted to Celsius when NWS supplies
+Fahrenheit, and wind speed strings are converted to kilometers per hour.
+
+Alert timing fields are parsed best-effort. Invalid per-alert timestamps are
+left unset rather than failing the whole alert run. Missing alert IDs are
+synthesized from the run snapshot time and array position.
+
+Forecast discussion parsing requires an issue time. Weather story entries require
+start time, end time, and update time.
+
+## Failure Behavior
+
+Constructor validation failures stop daemon startup. Polling failures are
+returned to the scheduler. JSON sources still emit raw payloads when only
+minimal metadata decoding fails. Forecast discussion polling fails if the HTML
+cannot be parsed enough to determine the issue time.

+# Open-Meteo Integration Notes
+
+## Purpose
+
+This document describes the Open-Meteo API usage currently implemented by
+`weatherfeeder`. It is for developers and operators maintaining Open-Meteo
+source URLs, normalizers, fixtures, and tests.
+
+General config syntax belongs in [configuration](../config.md). Emitted JSON
+events are documented in [event wire contract](events.md).
+
+## Implemented Drivers
+
+| Driver | Kind | Raw schema | Canonical schema |
+| --- | --- | --- | --- |
+| `openmeteo_observation` | `observation` | `raw.openmeteo.current.v1` | `weather.observation.v1` |
+| `openmeteo_forecast` | `forecast` | `raw.openmeteo.hourly.forecast.v1` | `weather.forecast.v1` |
+
+## Config Requirements
+
+Both drivers require HTTP source params:
+
+- `url`
+- `user_agent`
+
+The shared HTTP helper also accepts `conditional`, `http_timeout`, and
+`http_response_body_limit_bytes`. Conditional requests are enabled by default;
+an upstream `304 Not Modified` response emits no event for that poll.
+
+## Upstream Shapes Used
+
+`openmeteo_observation` expects a JSON response with top-level location/timezone
+metadata and a `current` object. The normalizer uses:
+
+- `latitude`, `longitude`, `timezone`, `utc_offset_seconds`;
+- `current.time`;
+- current temperature, apparent temperature, relative humidity, weather code,
+  wind speed/direction/gusts, pressure, and `is_day`.
+
+`openmeteo_forecast` expects top-level location/timezone metadata and an
+array-oriented `hourly` object. The normalizer uses:
+
+- `hourly.time`;
+- hourly temperature, apparent temperature, dew point, relative humidity,
+  precipitation probability, precipitation amount, snowfall, weather code,
+  pressure, wind speed/direction/gusts, `is_day`, cloud cover, visibility, and
+  UV index.
+
+Open-Meteo field presence is allowed to vary. Missing optional arrays produce
+nil canonical fields for the affected periods.
+
+## Accept Header
+
+Open-Meteo sources request:
+
+```text
+application/json
+```
+
+## Time Handling
+
+Open-Meteo timestamps often omit an explicit offset. The provider helper parses
+times by using the returned `timezone` or `utc_offset_seconds` when needed.
+
+Observation source events set `effective_at` from `current.time` when it can be
+parsed. Hourly forecast source events prefer `current.time`, then the first
+non-empty `hourly.time` entry.
+
+The hourly forecast normalizer sets canonical `issuedAt` from the incoming event
+`emitted_at` when present, otherwise from the first hourly period start.
+Normalized forecast `effective_at` matches `issuedAt`.
+
+## Mapping Notes
+
+Open-Meteo is not a station feed. Weatherfeeder synthesizes canonical
+station/location IDs from latitude and longitude when both are available.
+
+Open-Meteo weather codes are WMO codes and are treated as authoritative.
+Canonical text is derived from the WMO code and day/night hint.
+
+Wind speed and gust fields are treated as kilometers per hour. Pressure values
+are treated as hPa and converted to Pa. Snowfall values are treated as
+centimeters and converted to millimeters.
+
+Hourly forecast period end time is the next period start. The last period uses
+the previous interval length, or one hour when there is no previous interval.
+
+## Failure Behavior
+
+Constructor validation failures stop daemon startup. Polling failures are
+returned to the scheduler. Metadata decoding failures in sources still allow raw
+payload emission when the HTTP response itself succeeded.
+
+Normalization fails when required time data is missing or invalid, such as an
+empty `hourly.time` array for hourly forecasts.

+# OpenWeather Integration Notes
+
+## Purpose
+
+This document describes the OpenWeather current-weather usage implemented by
+`weatherfeeder`. It is for developers and operators maintaining OpenWeather
+source URLs, normalizers, fixtures, and tests.
+
+General config syntax belongs in [configuration](../config.md). Emitted JSON
+events are documented in [event wire contract](events.md).
+
+## Implemented Driver
+
+| Driver | Kind | Raw schema | Canonical schema |
+| --- | --- | --- | --- |
+| `openweather_observation` | `observation` | `raw.openweather.current.v1` | `weather.observation.v1` |
+
+Only current-weather observation polling is registered for OpenWeather.
+
+## Config Requirements
+
+The driver requires HTTP source params:
+
+- `url`
+- `user_agent`
+
+The shared HTTP helper also accepts `conditional`, `http_timeout`, and
+`http_response_body_limit_bytes`. Conditional requests are enabled by default;
+an upstream `304 Not Modified` response emits no event for that poll.
+
+The configured URL must include:
+
+```text
+units=metric
+```
+
+Startup fails if `units` is omitted or set to another value. Keep OpenWeather
+API keys out of committed configs. Use local config management or deployment
+secrets for the `appid` query parameter.
+
+## Upstream Shape Used
+
+The source emits the full current-weather JSON payload as a raw event. The
+normalizer uses:
+
+- `coord.lat`, `coord.lon`;
+- primary `weather[0]` condition ID, description, and icon;
+- `main.temp`, `main.feels_like`, `main.pressure`, `main.humidity`, and
+  optional `main.sea_level`;
+- `visibility`;
+- `wind.speed`, `wind.deg`, and `wind.gust`;
+- `dt`;
+- `sys.sunrise` and `sys.sunset`;
+- `id` and `name`.
+
+## Accept Header
+
+OpenWeather sources request:
+
+```text
+application/json
+```
+
+## Time Handling
+
+Source events set `effective_at` from `dt` when it is present and positive.
+The normalizer also uses `dt` as the canonical observation timestamp and
+normalized effective time.
+
+## Mapping Notes
+
+Metric units are required so canonical unit conversion is deterministic:
+
+- `main.temp` and `main.feels_like` are treated as Celsius;
+- `wind.speed` and `wind.gust` are treated as meters per second and converted to
+  kilometers per hour;
+- pressure values are treated as hPa and converted to Pa.
+
+The primary condition is `weather[0]`. OpenWeather condition IDs are mapped into
+the canonical WMO code vocabulary. The human text description is preserved from
+the provider description.
+
+Day/night is inferred from the OpenWeather icon suffix when available, otherwise
+from sunrise and sunset bounds.
+
+The station ID uses the OpenWeather city ID when present. If no city ID is
+present, weatherfeeder synthesizes an ID from coordinates. The station name uses
+the provider `name`, falling back to `OpenWeatherMap` when blank.
+
+## Failure Behavior
+
+Constructor validation failures stop daemon startup. Polling also re-checks the
+metric-unit requirement before fetching. HTTP failures are returned to the
+scheduler. Metadata decoding failures in the source still allow raw payload
+emission when the HTTP response itself succeeded.

+# Postgres Integration
+
+This document is the canonical table contract for the optional `postgres` sink.
+It describes the schema created and written by weatherfeeder through feedkit's
+Postgres sink.
+
+Configure the sink as described in [configuration](../config.md#postgres).
+
+## Initialization And Writes
+
+At startup, each configured Postgres sink opens the database and runs
+`CREATE TABLE IF NOT EXISTS` for every weatherfeeder table, followed by
+`CREATE INDEX IF NOT EXISTS` for every configured index.
+
+This initialization creates missing tables and indexes only. It does not alter
+existing tables, migrate column definitions, drop old objects, or backfill data.
+Schema changes require operator-managed database migration.
+
+Events are mapped only for canonical weather schemas:
+
+- `weather.observation.v1`
+- `weather.forecast.v1`
+- `weather.forecast_discussion.v1`
+- `weather.weather_story.v1`
+- `weather.alert.v1`
+
+Unsupported schemas produce no writes for this sink. Mapped events are inserted
+transactionally. Inserts use ordinary `INSERT`; duplicate primary keys fail the
+write.
+

+# Normalizer Internals
+
+## Purpose
+
+Normalizers convert raw provider events into canonical weather events. They are
+weather-domain mapping code and should stay independent of runtime wiring,
+source polling, and sink persistence.
+
+Detailed package conventions live in `internal/normalizers/doc.go`.
+
+## Inputs And Outputs
+
+Inputs are raw feed events whose schemas identify provider payload shape.
+Outputs are canonical feed events using `model` payloads and `weather.*`
+schemas.
+
+Current mappings:
+
+| Raw schema | Canonical schema |
+| --- | --- |
+| `raw.nws.observation.v1` | `weather.observation.v1` |
+| `raw.openmeteo.current.v1` | `weather.observation.v1` |
+| `raw.openweather.current.v1` | `weather.observation.v1` |
+| `raw.nws.hourly.forecast.v1` | `weather.forecast.v1` |
+| `raw.nws.narrative.forecast.v1` | `weather.forecast.v1` |
+| `raw.openmeteo.hourly.forecast.v1` | `weather.forecast.v1` |
+| `raw.nws.forecast_discussion.v1` | `weather.forecast_discussion.v1` |
+| `raw.nws.weatherstories.v1` | `weather.weather_story.v1` |
+| `raw.nws.alerts.v1` | `weather.alert.v1` |
+
+## Boundaries
+
+- Normalizers match by `Event.Schema`.
+- Normalizers decode raw payloads into provider structs.
+- Normalizers map provider data into canonical `model` payloads.
+- Normalizers do not fetch network data, read config, route events, or write
+  sinks.
+- Shared cross-provider behavior belongs in `internal/normalizers/common`.
+- Provider-specific helper logic shared with sources belongs in
+  `internal/providers/<provider>`.
+
+## Config Fields Used
+
+Normalizers do not read config. They operate only on incoming events.
+
+## External Adapters Used
+
+Runtime composition creates feedkit's normalize processor with
+`RequireMatch=false`. Events without a matching normalizer pass through
+unchanged.
+
+Weatherfeeder registers normalizers in a stable order:
+
+1. NWS
+2. Open-Meteo
+3. OpenWeather
+
+The current normalizers avoid ambiguous matches by using schema equality.
+
+## State
+
+Normalizers should be stateless. Shared helpers should be deterministic and free
+of I/O.
+
+## Failure Behavior
+
+Malformed required raw payload data should produce contextual errors from the
+owning normalizer. Successful normalization validates the output event before it
+continues through the pipeline.
+
+`internal/normalizers/common.Finalize` preserves the input event envelope except
+for schema, payload, and effective time. It also rounds canonical float values
+to four digits after the decimal point.

+# Postgres Sink Internals
+
+## Purpose
+
+`internal/sinks/postgres` defines weatherfeeder's canonical-event-to-Postgres
+mapping. It supplies a schema definition and mapper to feedkit's generic
+Postgres sink.
+
+The consumer-facing table contract is
+[`docs/integrations/postgres.md`](../integrations/postgres.md). This document
+describes the internal ownership boundary.
+
+## Inputs And Outputs
+
+Inputs are canonical feed events. The mapper currently handles these schemas:
+
+- `weather.observation.v1`
+- `weather.forecast.v1`
+- `weather.forecast_discussion.v1`
+- `weather.weather_story.v1`
+- `weather.alert.v1`
+
+Outputs are feedkit `PostgresWrite` values for weatherfeeder-owned tables.
+Unsupported schemas produce no writes and no error.
+
+## Boundaries
+
+- Weatherfeeder owns table definitions in `schema.go`.
+- Weatherfeeder owns canonical payload mapping in `map.go`.
+- Feedkit owns database opening, table and index creation, transactions,
+  inserts, context-aware consumption, and prune execution.
+- Postgres mapping consumes canonical events only. It should not understand raw
+  provider schemas.
+
+## Config Fields Used
+
+Weatherfeeder registers the `postgres` sink by passing `PostgresSchema()` to
+feedkit. Feedkit parses sink params:
+
+- `uri`
+- `username`
+- `password`
+- `prune`, optional duration
+
+Weatherfeeder-owned mapper code does not read config directly.
+
+## External Adapters Used
+
+The runtime registers the sink with:
+
+```go
+sinkReg.Register("postgres", fksinks.PostgresFactory(wfpgsink.PostgresSchema()))
+```
+
+Feedkit validates events at the sink boundary, calls the weatherfeeder mapper,
+validates writes against the compiled schema, inserts rows in a transaction, and
+optionally prunes rows older than the configured window.
+
+## State
+
+The mapper is stateless. Durable state is stored in Postgres through feedkit's
+sink implementation.
+
+## Mapping Rules
+
+Parent rows preserve event envelope fields where the table supports them:
+
+- `event_id`
+- `event_kind`
+- `event_source`
+- `event_schema`
+- `event_emitted_at`
+- `event_effective_at`
+
+Child rows use positional indexes to preserve canonical array order:
+
+- `weather_index`
+- `period_index`
+- `message_index`
+- `story_index`
+- `alert_index`
+- `reference_index`
+
+Required canonical fields are validated before writes are returned:
+
+- observations require `timestamp`;
+- forecasts require `issuedAt` and `product`, and each period requires
+  `startTime` and `endTime`;
+- forecast discussions require `issuedAt` and `product`;
+- weather story runs require `asOf`, and each story requires `startTime`,
+  `endTime`, and `updatedAt`;
+- alert runs require `asOf`, and each alert requires `id`.
+
+Nullable canonical values are converted to SQL nulls by mapper helpers.
+Observation present-weather raw values are stored as compact JSON text.
+
+## Failure Behavior
+
+Payload decode failures, missing required fields, invalid compact JSON values,
+or schema/write mismatches return errors to feedkit's sink. Feedkit rolls back
+the transaction when a write fails.
+
+Unsupported canonical schemas are ignored by this mapper so other routed events
+can use different sinks without Postgres-specific failures.
+
+## Tests To Inspect
+
+- `internal/sinks/postgres/schema_test.go`
+- `internal/sinks/postgres/map_test.go`
+- feedkit Postgres sink tests when changing generic sink behavior assumptions
+
+## Invariants
+
+- Persist only canonical schemas.
+- Preserve event envelope fields in parent rows.
+- Preserve array order with child positional indexes.
+- Validate required fields before writing.
+- Keep table-contract docs synchronized with schema and mapper changes.

+# Runtime Internals
+
+## Purpose
+
+`cmd/weatherfeeder` wires the daemon together. It owns process setup and runtime
+composition; provider mapping, source fetching details, and sink persistence
+rules stay in their owning packages.
+
+## Inputs And Outputs
+
+The executable reads `config.yml` from the current working directory through
+feedkit config loading. It builds configured sources, scheduler jobs, sinks, and
+routes, then runs source polling and sink dispatch until shutdown.
+
+Inputs are configured source polls. Outputs are feed events delivered to the
+configured sinks.
+
+## Runtime Flow
+
+The implemented flow is:
+
+1. load `config.yml`;
+2. register weatherfeeder source drivers;
+3. register feedkit built-in sinks and the weatherfeeder Postgres sink;
+4. build source inputs and scheduler jobs;
+5. validate configured expected kinds against source-advertised kinds;
+6. build sinks and compile routes;
+7. run the processor chain `normalize`, then `dedupe`;
+8. run the scheduler and dispatcher concurrently;
+9. shut down on signal or fatal scheduler/dispatcher error.
+
+The in-process event channel is buffered to 256 events. The dedupe processor is
+bounded by `dedupeMaxEntries`, currently 2048.
+
+## Boundaries
+
+- Runtime composition belongs in `cmd/weatherfeeder/main.go`.
+- Source driver behavior belongs under `internal/sources`.
+- Normalizer behavior belongs under `internal/normalizers`.
+- Canonical payloads and schema strings belong in `model` and `standards`.
+- Postgres mapping belongs under `internal/sinks/postgres`.
+
+`cmd/weatherfeeder` should stay thin and should not contain provider parsing,
+canonical mapping, or table-mapping rules.
+
+## Config Fields Used
+
+Runtime wiring consumes the feedkit top-level config sections:
+
+- `sources`: source driver selection, source name, mode, cadence, expected kinds,
+  and driver params;
+- `sinks`: sink driver selection, sink name, and sink params;
+- `routes`: event-kind routing to named sinks.
+
+The executable does not expose CLI flags or config path discovery.
+
+## External Adapters Used
+
+Runtime composition uses feedkit for:
+
+- config loading;
+- source registry and expected-kind validation;
+- scheduler job construction;
+- processor registry and chain execution;
+- normalization and dedupe processors;
+- sink registry and built-in sinks;
+- route compilation and dispatch.
+
+Weatherfeeder registers its own source drivers and its Postgres schema mapper.
+
+## State
+
+Weatherfeeder-owned runtime state is in process:
+
+- event channel contents;
+- the bounded dedupe key set;
+- source instances and their HTTP conditional validators;
+- scheduler and dispatcher goroutines.
+
+There is no weatherfeeder-owned durable scheduler state, checkpoint, replay log,
+or resume marker. Durable persistence is owned by configured external sinks.
+
+## Failure Behavior
+
+Startup failures are fatal and include context such as config index, source name,
+sink name, driver name, or the operation that failed.
+
+At runtime, scheduler and dispatcher errors are sent to a shared error channel.
+Context cancellation and deadline errors are treated as normal shutdown. Any
+other scheduler or dispatcher error is logged as fatal and cancels the process
+context.
+
+The daemon handles `os.Interrupt` and `SIGTERM` with `signal.NotifyContext`.
+After both runtime goroutines return, it logs `shutdown complete`.
+
+## Tests To Inspect
+
+- `cmd/weatherfeeder/main_test.go`
+- source registry tests under `internal/sources`
+- normalizer registration tests under `internal/normalizers`
+- feedkit scheduler, processor, dispatch, and sink tests when changing runtime
+  infrastructure usage
+
+## Invariants
+
+- Keep normalization before dedupe.
+- Keep queue sizes and dedupe bounds explicit.
+- Preserve context-aware shutdown.
+- Keep runtime wiring separate from domain mapping and persistence rules.
+- Keep startup validation failures loud and contextual.

+# Source Internals
+
+## Purpose
+
+Source packages poll upstream weather providers and emit raw feed events. They
+are adapters, not canonical mappers.
+
+Sources should decode only the metadata needed for event identity, effective
+time, and routing policy. Full provider payload interpretation belongs in
+normalizers.
+
+## Inputs And Outputs
+
+Inputs are feedkit `config.SourceConfig` values and upstream HTTP responses.
+Outputs are feed events whose payloads are raw provider JSON and whose schemas
+come from `standards`.
+
+Current drivers:
+
+| Driver | Kind | Raw schema |
+| --- | --- | --- |
+| `nws_observation` | `observation` | `raw.nws.observation.v1` |
+| `nws_alerts` | `alert` | `raw.nws.alerts.v1` |
+| `nws_forecast_hourly` | `forecast` | `raw.nws.hourly.forecast.v1` |
+| `nws_forecast_narrative` | `forecast` | `raw.nws.narrative.forecast.v1` |
+| `nws_forecast_discussion` | `forecast_discussion` | `raw.nws.forecast_discussion.v1` |
+| `nws_weatherstories` | `weather_story` | `raw.nws.weatherstories.v1` |
+| `openmeteo_observation` | `observation` | `raw.openmeteo.current.v1` |
+| `openmeteo_forecast` | `forecast` | `raw.openmeteo.hourly.forecast.v1` |
+| `openweather_observation` | `observation` | `raw.openweather.current.v1` |
+
+## Boundaries
+
+- Source constructors validate source-specific params.
+- Sources use feedkit HTTP helpers for HTTP polling.
+- Sources emit raw events and should not build canonical `model` payloads.
+- Provider helper packages under `internal/providers/<provider>` hold shared
+  parsing and validation helpers.
+- Registration is centralized in `internal/sources/builtins.go`.
+
+## Config Fields Used
+
+All current source drivers use feedkit `HTTPSource`.
+
+Required params:
+
+- `url`
+- `user_agent`
+
+Optional params:
+
+- `conditional`, default `true`;
+- `http_timeout`;
+- `http_response_body_limit_bytes`.
+
+OpenWeather observation sources additionally require the configured URL to use
+metric units. This is enforced by `internal/providers/openweather`.
+
+Source-level `kinds`, when configured, are validated against the source's
+advertised `Kinds()`.
+
+## External Adapters Used
+
+Sources use feedkit's HTTP helper for:
+
+- request construction;
+- `User-Agent` and `Accept` headers;
+- optional conditional GET validators;
+- response body size limits;
+- JSON raw-message fetches.
+
+NWS helpers parse NWS timestamps. Open-Meteo helpers parse provider-local times
+with timezone or UTC-offset data. OpenWeather helpers enforce metric-unit URLs.
+
+## State
+
+HTTP conditional validators are held in each source instance. They are not
+persisted across process restarts.
+
+## Failure Behavior
+
+Constructor failures are returned during startup and stop the daemon. Polling
+failures are returned to the scheduler.
+
+If a source cannot decode minimal metadata from an otherwise successful upstream
+response, it still emits the raw event when possible. The event then falls back
+to default ID/effective-time behavior from feedkit source helpers.
+
+Unchanged conditional responses return no events and no error.
+
+## Tests To Inspect
+
+- `internal/sources/builtins_test.go`
+- provider source tests under `internal/sources/nws`
+- provider source tests under `internal/sources/openmeteo`
+- provider source tests under `internal/sources/openweather`
+- provider helper tests under `internal/providers`
+
+## Invariants
+
+- Emit raw provider schemas from `standards`.
+- Keep provider-to-canonical mapping out of sources.
+- Keep HTTP behavior context-aware.
+- Keep driver registration explicit and stable.
+- Keep source tests independent of live upstream services.

+# Operations
+
+This document describes how to run and observe the `weatherfeeder` daemon in its
+current form. For configuration syntax, see [configuration](config.md). For the
+CLI surface, see [CLI reference](cli.md).
+
+## Normal Workflow
+
+1. Prepare `config.yml` in the process working directory.
+2. Start the daemon with `./weatherfeeder` or `go run .` from
+   `cmd/weatherfeeder`.
+3. Watch stderr logs for startup or runtime errors.
+4. Consume events from the configured sinks.
+5. Stop the process with `Ctrl-C` or `SIGTERM`.
+
+The daemon has no admin subcommands and no runtime reload command. Change the
+config file and restart the process to apply configuration changes.
+
+Maintained copyable configs are available under [`examples/`](../examples/).
+
+## Runtime Lifecycle
+
+On startup, `weatherfeeder`:
+
+1. loads `config.yml` from the current working directory;
+2. registers built-in source drivers;
+3. registers stdout, NATS, and weatherfeeder Postgres sink drivers;
+4. builds sources and validates configured `kinds` against source metadata;
+5. builds sinks and compiles routes;
+6. starts the scheduler and dispatcher;
+7. processes events through normalization, then in-memory dedupe;
+8. routes processed events to configured sinks.
+
+Startup errors are fatal and terminate the process. Runtime poll, pipeline, and
+sink errors are logged and the process continues unless the scheduler or
+dispatcher returns a fatal error.
+
+## Logs
+
+The process uses the Go standard logger with date, time, and microseconds. Logs
+go to stderr.
+
+Common log prefixes:
+
+| Prefix | Meaning |
+|---|---|
+| `config load failed` | `config.yml` could not be read, parsed, or validated. |
+| `build source failed` | A source driver or its params are invalid. |
+| `source expected kinds validation failed` | Configured source `kinds` do not match the source driver. |
+| `build sink failed` | A sink driver or its params are invalid, or a sink could not initialize. |
+| `compile routes failed` | Routes reference invalid sinks or kinds. |
+| `scheduler: poll failed` | A source poll failed; the source will be polled again on its next interval. |
+| `dispatcher: pipeline error` | Normalization or dedupe failed for one event. |
+| `dispatch: sink ... failed consuming event` | A sink failed to consume one event. |
+| `shutdown complete` | Scheduler and dispatcher have exited. |
+
+## Scheduling And Polling
+
+Current weatherfeeder sources are polling sources. Each source uses its
+configured `every` interval. The scheduler applies jitter before the first poll
+and before each interval tick. If no jitter is configured in code, feedkit uses
+`min(every/10, 30s)`, capped at half the interval.
+
+Poll failures are logged and do not stop the daemon. A failed poll emits no
+events for that source until a subsequent poll succeeds.
+
+## Conditional HTTP Fetches
+
+All current sources use feedkit's HTTP polling helper. By default,
+`params.conditional` is `true`, so the helper keeps ETag and Last-Modified
+validators in memory for each source instance.
+
+If the upstream returns `304 Not Modified`, the source emits no events for that
+poll. Validator state is in memory only; restarting the process starts with no
+cached validators.
+
+## Processing And Dedupe
+
+Every event passes through normalization first and dedupe second.
+
+Normalizers match raw source schemas and produce canonical `weather.*.v1`
+payloads. If an event has no matching normalizer, the normalize processor passes
+it through unchanged.
+
+Dedupe keys by event ID and stores a bounded in-memory set of 2048 recent IDs.
+Duplicate IDs are dropped. Dedupe state is not persisted, so a restart starts
+with an empty dedupe set.
+
+## Routing And Sink Fanout
+
+Routes choose sinks by event kind. If `routes` is omitted, every sink receives
+every event kind. If a route omits `kinds`, that route also matches all kinds.
+
+The dispatcher creates one queue and one worker goroutine per sink. The default
+per-sink queue size is 64. `weatherfeeder` does not currently expose config
+fields for sink queue size, enqueue timeout, or consume timeout.
+
+Sink errors are logged per event. A sink failure does not stop other sinks from
+receiving the same event.
+
+## Sink Behavior
+
+### stdout
+
+The stdout sink validates each event and prints one JSON object per line to
+stdout. This is useful for local inspection and log forwarding.
+
+### NATS
+
+The NATS sink connects lazily on the first event, reuses the connection while it
+is open, and publishes each event as JSON to the configured subject. Connection,
+marshal, and publish failures are logged by the dispatch worker.
+
+### Postgres
+
+The Postgres sink opens the database during startup. It creates missing tables
+and indexes with `CREATE TABLE IF NOT EXISTS` and `CREATE INDEX IF NOT EXISTS`.
+It does not modify existing table definitions.
+
+Each mapped canonical event is written in one transaction. If `params.prune` is
+set, the sink deletes rows older than `now - prune` from every weatherfeeder
+table in that same transaction. See the
+[Postgres table contract](integrations/postgres.md).
+
+## State And Recovery
+
+`weatherfeeder` keeps only runtime state in process memory:
+
+- scheduler goroutines and timers;
+- HTTP conditional request validators;
+- event channel buffers;
+- per-sink fanout queues;
+- the dedupe ID set.
+
+Durable state is external sink state: NATS broker state outside this process and
+Postgres tables managed by the configured database.
+
+There is no internal checkpoint, replay log, or resume marker. To recover from a
+process failure, fix the underlying issue and restart the daemon from a working
+directory containing the desired `config.yml`.
+
+## Shutdown
+
+`weatherfeeder` listens for `os.Interrupt` and `SIGTERM`. On shutdown, the
+shared context is canceled. Scheduler jobs stop polling, dispatch workers stop,
+and the process logs `shutdown complete`.
+
+Queued sink work may be dropped when shutdown context cancellation reaches the
+fanout workers. Use external sink durability, such as Postgres or broker
+retention, for durable downstream state.
+
+## Caveats
+
+- There is no health-check endpoint.
+- There is no runtime config reload.
+- There are no built-in metrics.
+- Source conditional request state and dedupe state are reset by restart.
+- Existing Postgres schemas are not migrated automatically.

+# Architecture Policy
+
+## Purpose
+
+This document defines `weatherfeeder`'s development architecture and invariants for maintainers and LLM coding agents. It describes how the implemented system is built and how subsequent changes should preserve its boundaries.
+
+This is an inward-facing policy document. User-facing wire contracts belong in
+[`docs/integrations/events.md`](../integrations/events.md), and roadmap items
+belong under [`docs/roadmap/`](../roadmap/).
+
+## Project Shape
+
+`weatherfeeder` is a config-driven Go daemon that polls upstream weather providers, emits feed events, normalizes provider-specific raw payloads into canonical weather payloads, and routes those events to configured sinks.
+
+The implemented runtime flow is:
+
+1. `cmd/weatherfeeder` loads `config.yml` from the working directory.
+2. Source drivers are built through the source registry.
+3. Feedkit scheduler jobs poll sources and publish raw events onto an in-process event channel.
+4. A pipeline runs normalization, then in-memory dedupe.
+5. The dispatcher routes processed events to configured sinks by event kind.
+6. Sinks consume events independently through feedkit fanout workers.
+
+Canonical payload structs live in `model`. Schema identifiers and cross-provider wire conventions live in `standards`. Source adapters live under `internal/sources`. Normalizers live under `internal/normalizers`. Provider-specific parsing helpers shared by sources and normalizers live under `internal/providers`. Sink-specific persistence mapping lives under `internal/sinks`.
+
+## Core Design Principles
+
+- Hexagonal boundaries: provider APIs, config loading, scheduling, dispatch, and sinks are external mechanisms around the weather domain model and normalization logic.
+- Raw-to-canonical flow: sources should fetch and envelope raw provider payloads; normalizers should own provider-to-canonical mapping.
+- Schema-based routing: normalizers match on event schema, not source name or event kind.
+- Composable registries: source drivers, normalizers, processors, and sinks are assembled explicitly through registries.
+- Bounded concurrency: scheduling and sink fanout are concurrent, but the application should keep queues, goroutine ownership, logging, and cancellation behavior visible.
+- Standard-library-first: use the Go standard library unless a narrow dependency materially improves maintainability or interoperability.
+- Current-behavior docs: outside roadmap files, document only implemented behavior.
+
+## Architectural Boundaries
+
+Core/domain logic:
+
+- `model` defines canonical payload structs and JSON field names.
+- `standards` defines schema strings, versioning conventions, WMO constants, and shared wire policy.
+- Normalizer mapping code is domain logic and should stay independent of CLI setup, filesystem paths, sink details, and runtime orchestration.
+
+Adapters:
+
+- Source adapters under `internal/sources/<provider>` fetch upstream data and produce raw feed events.
+- Sink adapters under `internal/sinks/<sink>` map canonical events to external systems.
+- Provider helper packages under `internal/providers/<provider>` contain pure parsing or provider-specific helper logic shared by sources and normalizers.
+
+Runtime composition:
+
+- `cmd/weatherfeeder/main.go` owns process wiring: config load, registry setup, scheduler jobs, processor chain, dispatcher, signal cancellation, and logging.
+- It should remain thin. Do not move provider mapping or sink persistence rules into `cmd/weatherfeeder`.
+
+Tests and examples:
+
+- The sample `cmd/weatherfeeder/config.yml` is executable test input and is load-tested.
+- Tests should keep exercising package contracts directly rather than relying only on full-daemon execution.
+
+## Modules Or Processing Steps
+
+The implemented processing steps are source polling, normalization, dedupe, and sink dispatch.
+
+Source contract:
+
+- Build from `feedkit/config.SourceConfig`.
+- Validate required driver params inside the source constructor.
+- Advertise emitted event kinds through `Kinds()` when possible.
+- Emit raw schemas from `standards`.
+- Decode only minimal metadata needed for event identity and effective time; leave full provider decoding to normalizers.
+- Respect `context.Context` during network work.
+
+Normalizer contract:
+
+- One normalizer type per normalizer file.
+- Match by `Event.Schema`.
+- Decode raw payloads into provider structs.
+- Map to canonical `model` payloads.
+- Preserve the incoming event envelope except for intentional schema, payload, and effective-time changes.
+- Use shared helpers in `internal/normalizers/common` for cross-provider behavior.
+- Follow the detailed normalizer conventions in `internal/normalizers/doc.go`.
+
+Sink contract:
+
+- Consume canonical schemas, not provider raw schemas.
+- Keep sink mapping isolated from normalizers and sources.
+- Preserve event envelope fields in durable storage where the sink schema supports it.
+- Validate required canonical fields before writing.
+
+## State, Inputs, and Outputs
+
+Inputs are configured source polls. The daemon currently uses feedkit's YAML config model with sources, sinks, and routes.
+
+Outputs are feed events sent to configured sinks. Implemented sink support comes from feedkit built-ins plus weatherfeeder's Postgres schema mapping. The sample config includes stdout and NATS routes; Postgres is configured as an optional commented example.
+
+The daemon's own state is in-process:
+
+- the event channel buffers events during runtime;
+- the dedupe processor stores a bounded in-memory key set;
+- source instances may keep HTTP conditional request state through feedkit HTTP source helpers;
+- scheduler and dispatcher state is not persisted by `weatherfeeder`.
+
+Durable persistence is an external sink concern. The Postgres table contract is
+documented in [`docs/integrations/postgres.md`](../integrations/postgres.md);
+the consumer-facing event contract is documented in
+[`docs/integrations/events.md`](../integrations/events.md).
+
+## Configuration and CLI Boundaries
+
+The implemented executable reads `config.yml` from the current working directory. It does not currently expose CLI flags or config path discovery.
+
+Configuration shape is owned by feedkit's config package:
+
+- `sources` define named source drivers, mode, poll cadence, expected kinds, and driver params.
+- `sinks` define named sink drivers and sink params.
+- `routes` connect event kinds to sinks.
+
+Weatherfeeder-specific config policy belongs in source and sink constructors, registry setup, and tests. Do not spread config parsing through domain model or normalizer packages.
+
+[`docs/config.md`](../config.md) and [`docs/cli.md`](../cli.md) are the
+canonical user/operator references. This policy should stay architectural and
+avoid duplicating those references.
+
+## Errors, Logging, and Diagnostics
+
+`cmd/weatherfeeder` uses the standard library `log` package with timestamps and microseconds.
+
+Startup errors are fatal and include config index, source/sink name, driver name, or operation context where available. Runtime scheduler and dispatcher errors are reported through logs; context cancellation and deadline errors are treated as shutdown conditions.
+
+Normalizers and sink mappers should wrap errors with operation and payload context, for example decode, parse, map, scan, or required-field context. Avoid logging or returning whole upstream payloads by default.
+
+The daemon handles `os.Interrupt` and `SIGTERM` through `signal.NotifyContext`. Sources, sinks, scheduler jobs, dispatcher, and processors should respect `context.Context`.
+
+## Testing Expectations
+
+When changing behavior, inspect or add focused tests in the owning package.
+
+Expected coverage by change type:
+
+- Source drivers: constructor behavior, advertised kinds, poll event schema/kind, effective-time policy, unchanged responses, and malformed metadata handling.
+- Normalizers: schema matching, canonical schema output, key field mapping, effective time, malformed required fields, and wire-shape regressions.
+- Provider helpers: parsing edge cases and fixtures.
+- Runtime wiring: config loading, source registry build, scheduler job creation, processor ordering, pass-through behavior, and dedupe behavior.
+- Postgres sink: schema shape, mapper writes, required-field validation, nullable handling, and compact JSON behavior.
+- Documentation-sensitive examples: keep sample config loadable.
+
+Use local test servers and fixtures rather than real upstream services. Full-package tests should remain fast and deterministic.
+
+## Dependency Policy
+
+Prefer the Go standard library for parsing, HTTP handling, time handling, logging, and tests where reasonable.
+
+Existing broad runtime composition is delegated to `feedkit`, which provides config, sources, scheduler, processors, dispatch, and sinks. Keep weatherfeeder-specific code from depending directly on low-level external clients when feedkit or a small adapter can contain that dependency.
+
+Third-party dependencies should be narrow, justified, and preferably de facto standard for their purpose. YAML parsing through feedkit is an acceptable example. Do not add dependencies for small conveniences, and do not let dependency-specific types leak across package boundaries unless that dependency is the package's explicit contract.
+
+## Documentation Expectations
+
+Documentation must follow [`docs/policy/documentation.md`](documentation.md).
+
+Rules for architecture-related docs:
+
+- Current-behavior docs must describe implemented behavior only.
+- Roadmap or speculative work belongs only under `docs/roadmap/`.
+- Prefer links to canonical docs over repeated reference material.
+- Update docs in the same change when modifying schemas, config behavior, runtime behavior, adapters, or persistence contracts.
+
+## Architectural Invariants
+
+- Keep `cmd/weatherfeeder` as composition code, not domain logic.
+- Keep source fetching separate from normalization.
+- Keep normalizers matched by schema constants from `standards`.
+- Keep canonical payload structs in `model` and treat JSON tags as wire contract.
+- Keep provider-specific helpers under `internal/providers/<provider>` when shared by sources and normalizers.
+- Keep cross-provider normalizer helpers pure and deterministic.
+- Keep sink persistence mapping isolated under `internal/sinks/<sink>`.
+- Preserve explicit registry-based extension points for sources and normalizers.
+- Preserve context-aware shutdown and bounded in-process queues.
+- Avoid broad dependencies without clear architectural value.
+
+## Non-Goals
+
+- `weatherfeeder` is not an HTTP API. API serving belongs to separate consumers such as `weatherapi`.
+- `weatherfeeder` does not own long-term durable state except through configured external sinks.
+- `weatherfeeder` does not provide a general plugin runtime; new built-in providers and sinks are registered in code.
+- Architecture policy is not a CLI, config, or wire-contract reference.

+# Development Policy
+
+## Purpose
+
+This document describes how to change `weatherfeeder` safely. It is for
+maintainers and coding agents working in the repository.
+
+Use this alongside the [architecture policy](architecture.md). User-facing CLI,
+configuration, operations, and wire-contract details belong in their canonical
+docs, not here.
+
+## Repository Layout
+
+- `cmd/weatherfeeder/`: executable wiring, sample `config.yml`, and runtime
+  composition tests.
+- `model/`: canonical weather payload structs. JSON tags are part of the wire
+  contract.
+- `standards/`: schema strings, versioning conventions, WMO constants, and
+  shared wire-format policy.
+- `internal/sources/`: source adapters that poll upstream providers and emit raw
+  feed events.
+- `internal/normalizers/`: raw-to-canonical event transforms.
+- `internal/providers/`: pure provider helper code shared by sources and
+  normalizers.
+- `internal/sinks/postgres/`: weatherfeeder-owned Postgres schema and canonical
+  event mapper.
+- `docs/`: current behavior, policies, integration contracts, and roadmap files.
+- `examples/`: maintained, copyable configuration examples.
+
+## Build And Test
+
+Run the full test suite before committing behavior or documentation changes that
+depend on code behavior:
+
+```sh
+go test ./...
+```
+
+Use narrower commands while iterating:
+
+```sh
+go test ./cmd/weatherfeeder
+go test ./internal/sources/...
+go test ./internal/normalizers/...
+go test ./internal/sinks/postgres
+```
+
+Format Go code before committing:
+
+```sh
+gofmt -w <changed-go-files>
+```
+
+Do not require live upstream weather services, NATS, or Postgres for unit tests.
+Use fixtures, local test servers, and package-level tests.
+
+## Coding Conventions
+
+- Keep `cmd/weatherfeeder` focused on composition: config load, registry setup,
+  scheduler jobs, processor chain, dispatch, signal handling, and logging.
+- Keep source fetching separate from normalizer mapping.
+- Match normalizers by schema constants from `standards`, not source names.
+- Keep provider-specific helper code under `internal/providers/<provider>` when
+  both sources and normalizers use it.
+- Keep cross-provider normalizer helpers pure and deterministic under
+  `internal/normalizers/common`.
+- Keep sink persistence mapping isolated under `internal/sinks/<sink>`.
+- Wrap errors with operation context, but do not include whole upstream payloads
+  in errors or logs by default.
+- Prefer explicit registries and small package-level constructors over hidden
+  global behavior.
+
+## Dependency Policy
+
+Prefer the Go standard library unless a dependency materially improves
+maintainability or interoperability.
+
+`feedkit` owns generic daemon infrastructure for config, HTTP source helpers,
+scheduling, processors, dispatch, and sinks. Weatherfeeder code should contain
+weather-domain behavior and narrow adapter logic rather than duplicating feedkit
+infrastructure.
+
+Do not add broad dependencies for small conveniences. Do not let
+dependency-specific types leak across package boundaries unless that dependency
+is the package contract.
+
+## Adding Config Fields
+
+Generic config shape is owned by feedkit. Weatherfeeder-specific config behavior
+belongs in source or sink constructors, registry setup, and tests.
+
+When adding config behavior:
+
+- validate required params at the adapter boundary;
+- keep secrets in environment variables or placeholders, not committed values;
+- update [configuration docs](../config.md);
+- update maintained examples when the change affects normal operation;
+- add or update config-load tests for example files when practical.
+
+## Adding CLI Flags
+
+The executable currently reads `config.yml` from the current working directory.
+If CLI flags are added:
+
+- keep parsing in `cmd/weatherfeeder`;
+- avoid moving config policy into domain packages;
+- update [CLI docs](../cli.md);
+- update tests that exercise command behavior.
+
+## Adding A Source Driver
+
+Source drivers should fetch upstream data and emit raw events with minimal
+metadata decoding.
+
+Checklist:
+
+- implement the driver under `internal/sources/<provider>`;
+- build from `config.SourceConfig`;
+- validate required params in the constructor;
+- use feedkit HTTP helpers for HTTP polling when applicable;
+- emit raw schema constants from `standards`;
+- advertise emitted kinds through `Kinds()`;
+- decode only metadata needed for event ID and effective time;
+- register the driver in `internal/sources/builtins.go`;
+- add constructor, kind, and polling tests;
+- update config docs and examples when operators need new configuration;
+- add provider integration notes when the provider contract needs maintenance
+  context.
+
+## Adding A Normalizer
+
+Normalizers own provider-to-canonical mapping.
+
+Checklist:
+
+- add one normalizer type per normalizer file;
+- match using `Event.Schema`;
+- decode raw payloads into provider structs;
+- map to canonical `model` payloads;
+- use `internal/normalizers/common.Finalize` so envelope handling and float
+  rounding stay consistent;
+- preserve input envelope fields except schema, payload, and effective time;
+- register through the provider package and `internal/normalizers/builtins.go`;
+- add tests for schema matching, key payload fields, effective time, malformed
+  required data, and output validation.
+
+## Adding Canonical Models Or Schemas
+
+Canonical event changes affect multiple contracts.
+
+Checklist:
+
+- update payload structs in `model`;
+- add or update schema constants in `standards`;
+- update [event wire contract docs](../integrations/events.md);
+- update normalizers that produce the schema;
+- update Postgres mapping if the schema is persisted;
+- add tests for wire shape and mapper behavior.
+
+## Adding Postgres Mapping
+
+Weatherfeeder owns the canonical-event-to-table mapping. Feedkit owns the
+generic Postgres sink mechanics.
+
+Checklist:
+
+- update `internal/sinks/postgres/schema.go`;
+- update `internal/sinks/postgres/map.go`;
+- preserve event envelope columns in parent rows when the table supports them;
+- validate required canonical fields before writing;
+- use positional indexes for child rows that represent arrays;
+- update mapper and schema tests;
+- update [Postgres integration docs](../integrations/postgres.md) when the table
+  contract changes.
+
+## Examples And Documentation
+
+Documentation must follow the [documentation policy](documentation.md).
+
+When behavior changes, update the canonical docs in the same change:
+
+- config shape: `docs/config.md`;
+- CLI behavior: `docs/cli.md`;
+- operations and recovery: `docs/operations.md`;
+- troubleshooting: `docs/troubleshooting.md`;
+- external contracts: `docs/integrations/`;
+- internal component behavior: `docs/internal/`;
+- copyable configs: `examples/`.
+
+Keep roadmap content under `docs/roadmap/`. Current-behavior docs must describe
+implemented behavior only.
+
+## Review Checklist
+
+Before committing:
+
+- run focused tests for changed packages;
+- run `go test ./...` for broad behavior or documentation changes tied to code;
+- verify maintained examples still load when examples or config docs changed;
+- check links in changed docs;
+- search for stale paths, unsupported features, and secret-like values;
+- keep unrelated refactors out of the change.

+# Go Project Documentation Policy
+
+## Purpose
+
+Project documentation must help four audiences:
+
+1. users who need to run the application;
+2. administrators/operators who need to configure and operate it;
+3. developers who need to understand and change it safely;
+4. LLM coding agents that need clear scope, boundaries, and invariants.
+
+Docs should be accurate, concise, task-oriented, and organized by audience. Prefer links to canonical docs over repetition.
+
+## Core Rules
+
+### 1. Keep docs concise
+
+Each document should cover a defined scope and only the essentials for that scope.
+
+Avoid:
+- long background explanations;
+- repeated reference material;
+- implementation detail in user-facing docs;
+- aspirational language outside roadmap docs;
+- verbose examples where one minimal example is clearer.
+
+### 2. Document only implemented behavior outside roadmap files
+
+Unimplemented, planned, aspirational, experimental, or future work may be described only under:
+
+- `docs/roadmap/`
+
+No other documentation file, including `README.md`, should describe code, features, modules, stages, commands, config fields, or behaviors that do not currently exist.
+
+If a feature is partial, non-roadmap docs may describe only the implemented portion and its current boundary.
+
+### 3. Use canonical homes
+
+Each type of information should have one canonical location.
+
+Canonical homes:
+
+- project purpose and quickstart: `README.md`
+- development principles: `docs/policy/architecture.md`
+- configuration reference: `docs/config.md`
+- CLI reference: `docs/cli.md`
+- operations and recovery: `docs/operations.md`
+- troubleshooting: `docs/troubleshooting.md`
+- implemented internals: `docs/internal/`
+- future work: `docs/roadmap/`
+- contributor workflow: `docs/policy/development.md`
+- copyable examples: `examples/`
+
+Other files should summarize briefly and link to the canonical source.
+
+### 4. Keep examples real
+
+Examples should be valid, maintained, and free of secrets.
+
+Where practical:
+- example configs should load successfully;
+- example commands should match real CLI syntax;
+- important examples should be covered by tests.
+
+## Documentation Profiles
+
+All projects require:
+
+- `README.md`
+- `docs/policy/architecture.md`
+
+Additional docs depend on the project.
+
+### Small library
+
+Recommended:
+- `docs/policy/development.md`, if contributor conventions are non-obvious
+
+### Simple CLI
+
+Required:
+- `docs/cli.md`
+
+Recommended:
+- `docs/policy/development.md`
+
+### Config-driven CLI
+
+Required:
+- `docs/cli.md`
+- `docs/config.md`
+
+Recommended:
+- `examples/`
+- `docs/policy/development.md`
+
+### Stateful or operator-facing application

+- `docs/operations.md`
+- `docs/internal/`
+- `docs/policy/development.md`
+
+Recommended:
+- `docs/troubleshooting.md`
+- validated examples under `examples/`
+
+## Required Documents
+
+### README.md
+
+**Audience:** users, administrators, operators
+
+The README is the outward-facing project orientation page.
+
+It should include, in order:
+
+1. concise description;
+2. elevator pitch;
+3. shortest useful command or usage example;
+4. links to targeted docs.
+
+The README should be short. It is not a manual.
+
+The “shortest useful command” means the simplest command that performs the project’s core use case. (It does not mean `app --help`.)
+
+### docs/policy/architecture.md
+
+**Audience:** developers, LLM coding agents
+
+`docs/policy/architecture.md` is required for every project.
+
+It is an inward-facing development policy document. It should describe how the project is intended to be built and changed.
+
+It should include:
+
+- project shape;
+- core design principles;
+- package and boundary philosophy;
+- state/persistence philosophy, if applicable;
+- external integration philosophy, if applicable;
+- error-handling and logging principles;
+- testing expectations;
+- documentation expectations;
+- architectural invariants;
+- explicit non-goals, if useful.
+
+For small projects, this file may be brief. It may simply state that the project is intentionally narrow, monolithic, and dependency-light.
+
+### docs/policy/development.md
+
+**Audience:** developers, LLM coding agents
+
+Required for projects maintained by humans and LLM coding agents.
+
+It should include:
+
+- repository layout;
+- build/test commands;
+- coding conventions;
+- dependency policy;
+- how to add config fields;
+- how to add CLI flags;
+- how to add stages/modules/adapters, if applicable;
+- how to update examples;
+- documentation update expectations.
+
+### docs/config.md
+
+**Audience:** administrators, operators, advanced users
+
+Required for applications with configuration files.
+
+It should include, in order:
+
+1. config file locations and discovery precedence;
+2. minimal working config;
+3. production-oriented config;
+4. full configuration reference;
+5. secrets handling, if applicable;
+6. links to maintained examples.
+
+The full configuration reference should be canonical.
+
+### docs/cli.md
+
+**Audience:** users, administrators, operators
+
+Required for CLI applications.
+
+It should include, in order:
+
+1. shortest useful command;
+2. command overview;
+3. complete flag reference;
+4. common workflows;
+5. diagnostic or recovery commands, if applicable.
+
+Explain when commands are useful, not just their syntax.
+
+### docs/operations.md
+
+**Audience:** administrators, operators
+
+Required for applications that maintain state, support resume behavior, run multiple stages, write durable artifacts, use remote storage, or require recovery procedures.
+
+It should cover:
+
+- normal workflow;
+- filesystem layout;
+- remote storage layout, if applicable;
+- logs and manifests;
+- resume/retry behavior;
+- cleanup behavior;
+- archive/backup behavior;
+- safe recovery procedures;
+- operational caveats.
+
+### docs/troubleshooting.md
+
+**Audience:** administrators, operators
+
+Recommended once recurring failure modes exist.
+
+Each entry should include:
+
+- symptom;
+- likely cause;
+- diagnostic command or inspection step;
+- safe fix;
+- relevant links.
+
+### docs/internal/
+
+**Audience:** developers, LLM coding agents
+
+Required for modular, staged, service-oriented, or orchestration projects.
+
+This directory describes implemented internal components. It is not the roadmap.
+
+Use one file per major component where useful.
+
+Each component doc should include:
+
+1. purpose;
+2. inputs and outputs;
+3. boundaries;
+4. config fields used;
+5. external adapters used;
+6. state or manifest behavior, if applicable;
+7. skip/resume behavior, if applicable;
+8. failure behavior;
+9. tests to inspect before changing;
+10. architectural invariants.
+
+### docs/roadmap/
+
+**Audience:** maintainers, developers, LLM coding agents
+
+This is the only place for planned, future, aspirational, experimental, or unimplemented work.
+
+Roadmap docs should clearly distinguish:
+
+- proposed work;
+- accepted plans;
+- deferred ideas;
+- rejected ideas;
+- implementation prompts or task breakdowns, if useful.
+
+Roadmap docs should not be confused with current behavior.
+
+### docs/integrations/
+
+**Audience:** developers, LLM coding agents
+
+Required for projects that depend on external CLIs, APIs, services, protocols, or file formats where the integration contract is important to maintain.
+
+This directory contains concise, versioned reference notes for external integration contracts. It should document only the parts of the external system that this project actually uses.
+
+Use one file per integration where useful.
+
+## Examples Directory
+
+Projects with non-trivial configuration or workflows should include `examples/`.
+
+Useful examples include:
+
+- minimal working config;
+- production-oriented config;
+- full annotated config;
+- local development config;
+- remote/object-storage config;
+- minimal session/input file.
+
+Examples should be valid, maintained, tested when practical, and linked from relevant docs.
+
+## Security and Privacy
+
+Docs and examples must not include:
+
+- real API keys;
+- tokens;
+- passwords;
+- private keys;
+- private environment dumps;
+- sensitive user data;
+- raw private transcripts;
+- private infrastructure details unless intentionally public.
+
+Document secret-handling mechanisms, not actual secret values.
+
+## Maintenance Rules
+
+When docs change, verify the affected behavior.
+
+Where practical:
+
+- load example config files in tests;
+- test CLI examples or command parser behavior;
+- validate documented flags against real flags;
+- remove stale references;
+- update links after renames;
+- keep roadmap content out of non-roadmap docs.
+
+If documentation and code disagree, fix the documentation and/or open a roadmap item; do not leave aspirational behavior in current-behavior docs.
+
+Documentation is complete only when it matches the current code.
+
+## Documentation Change Checklist
+
+Before merging documentation changes, verify:
+
+- README is concise and orientation-focused.
+- `docs/policy/architecture.md` describes development principles.
+- Future work appears only under `docs/roadmap/`.
+- User-facing docs avoid unnecessary internals.
+- Developer-facing docs preserve boundaries and invariants.
+- Config examples match the schema.
+- CLI examples match real commands and flags.
+- Defaults appear in the canonical config reference.
+- No secrets or private data are included.
+- Links are accurate.

+# Documentation Roadmap
+
+## Purpose
+
+This roadmap defines the work required to bring `weatherfeeder` documentation into compliance with [`docs/policy/documentation.md`](../policy/documentation.md) and the current implementation described by [`docs/policy/architecture.md`](../policy/architecture.md).
+
+This is a planning document only. Implementation stages must update current-behavior documentation so it reflects implemented code, and keep proposed or unimplemented work under `docs/roadmap/`.
+
+## Repository Documentation Inventory
+
+- `README.md`: keep and rewrite. It is the correct project orientation file, but it is stale: it says stdout is the only implemented sink, uses “current MVP” framing, and lacks a shortest useful run command and links to targeted docs.
+- `API.md`: move and rewrite. It currently acts as the event wire contract, but external integration contracts belong under `docs/integrations/`. It is also stale: it omits the emitted `kind` and `emitted_at` envelope fields, documents `effectiveAt` instead of the actual `effective_at` JSON field, lists only some raw schemas, and has duplicate alert `response` rows.
+- `docs/policy/documentation.md`: keep and lightly update only if needed. It is the controlling documentation policy and should not be duplicated elsewhere.
+- `docs/policy/architecture.md`: keep and lightly update after the documentation tree is migrated. Its architecture content is current, but its link to `API.md` should be updated when the wire contract moves to `docs/integrations/events.md`.
+- `docs/roadmap/spc.md`: keep. It is correctly located under roadmap because it describes unimplemented SPC outlook support.
+- `docs/roadmap/documentation.md`: create. This file is the current deliverable.
+- `cmd/weatherfeeder/config.yml`: keep and treat as an executable sample, but do not use it as the only operator-facing config reference. It includes live endpoints and a commented OpenWeather URL with an apparent real API key; future cleanup should remove or replace that secret-like value.
+- `internal/normalizers/doc.go`: keep and lightly update. It contains implemented developer guidance but incorrectly references `internal/standards/schema.go`; the actual package is `standards` at repository root.
+- `internal/normalizers/common/doc.go`: keep and lightly update if needed. It is concise and current.
+- `internal/providers/nws/doc.go`: keep and lightly update if needed. It documents implemented provider-helper boundaries.
+- `internal/providers/openweather/doc.go`: keep and lightly update. It references future forecasts/alerts in a comment; outside roadmap docs this should be rewritten to current behavior only.
+- `standards/doc.go`: keep and lightly update. It incorrectly says `internal/standards/doc.go`; actual path is `standards/doc.go`.
+- `model/doc.go`: keep and lightly update. It says JSON tags are wire contract for “stdout today; others later,” which is stale because NATS and Postgres are implemented.
+- `internal/sinks/postgres/doc.go`: keep and lightly update. It is the authoritative implemented Postgres table contract, but should be linked from `docs/integrations/postgres.md` instead of being the only discoverable operator/developer reference.
+- `examples/`: create new. No examples directory exists. Current example material is embedded in `cmd/weatherfeeder/config.yml` only.
+- `docs/config.md`: create new. Required because `weatherfeeder` is config-driven.
+- `docs/cli.md`: create new. Required because `weatherfeeder` is a command-line executable, even though it currently has no flags.
+- `docs/operations.md`: create new. Required because `weatherfeeder` is an operator-facing daemon with polling, concurrency, external sinks, retention/pruning, and shutdown behavior.
+- `docs/troubleshooting.md`: create new. Recommended and useful because recurring operator failures are visible in constructors and config validation.
+- `docs/policy/development.md`: create new. Required for a modular project maintained by humans and coding agents.
+- `docs/internal/`: create new. Required because the project is modular and staged.
+- `docs/integrations/`: create new. Required because the project depends on external weather APIs, NATS, Postgres, and an emitted event contract.
+
+## Policy Compliance Assessment
+
+Required missing documents:
+
+- `docs/cli.md`
+- `docs/config.md`
+- `docs/operations.md`
+- `docs/internal/`
+- `docs/policy/development.md`
+- `docs/integrations/` entries for important external contracts
+
+Recommended missing documents:
+
+- `docs/troubleshooting.md`
+- `examples/` with maintained config examples
+
+Existing stale or misplaced content:
+
+- `README.md` is not concise enough as a current quickstart and contains stale sink status.
+- `API.md` is in the wrong canonical home for an external integration contract and does not match `feedkit/event.Event` JSON tags.
+- Some package comments include stale path references or future-looking language outside roadmap files.
+- The sample config contains live endpoint examples and an OpenWeather URL with an apparent credential-like `appid` value in a commented block; examples should be secret-free.
+
+Unimplemented, historical, or roadmap-only content outside roadmap:
+
+- README “current MVP” phrasing is development-history framing and should be removed.
+- Comments such as “others later,” “forecasts/alerts later,” and “future expensive steps” should be rewritten or removed unless they describe an implemented boundary.
+- Do not move SPC outlook content out of `docs/roadmap/spc.md` until it is implemented.
+
+Examples needing work:
+
+- There is no `examples/` directory.
+- `cmd/weatherfeeder/config.yml` is load-tested by `cmd/weatherfeeder/main_test.go`, but it is not an ideal copyable public example because it includes local/operator-specific values and a commented API key-like OpenWeather URL.
+- Future examples should be checked with `feedkit/config.Load` or a weatherfeeder-specific test.
+
+Links needing verification:
+
+- Links from `README.md` to `API.md` should be changed to the new canonical event contract path if `API.md` is moved.
+- `docs/policy/architecture.md` links to `../../API.md`; update this after moving the contract.
+- Internal package comments referring to `internal/standards` need correction to `standards`.

+
+## File-by-File Rewrite Guidance
+
+### `README.md`
+
+Cover what the daemon does, the shortest useful command, and where to go next. Use implemented provider and product summaries from source/normalizer registries. Avoid full config tables, full wire schemas, history, “MVP” language, and stale sink limitations. Link to `docs/cli.md`, `docs/config.md`, `docs/operations.md`, `docs/integrations/events.md`, and `docs/policy/development.md`.
+
+Do not carry forward the claim that stdout is the only implemented sink.
+
+### `API.md`
+
+Move its canonical content to `docs/integrations/events.md` and either delete `API.md` or replace it with a short pointer only if backward-compatible repository links are required. The rewritten contract must inspect `../feedkit/event/event.go` before documenting envelope fields. Do not preserve camelCase envelope examples unless the code changes first.
+
+### `docs/config.md`
+
+Use feedkit config structs for generic fields and weatherfeeder source/sink constructors for driver-specific params. Link to examples instead of embedding all large configs. Avoid documenting feedkit stream-only params as actively used by weatherfeeder unless clearly marked as generic feedkit config accepted by the current config model; all current weatherfeeder sources are poll sources.
+
+### `docs/cli.md`
+
+State the current no-flags behavior plainly. Include that `weatherfeeder` expects `config.yml` in the current working directory. Do not document environment variables, subcommands, or alternate config paths unless implemented.
+
+### `docs/operations.md`
+
+Focus on running the daemon and operating sinks. Include signal shutdown, log behavior, conditional HTTP fetches, Postgres table creation, retention pruning, and no internal durable scheduler state. Avoid unsupported recovery commands.
+
+### `docs/troubleshooting.md`
+
+Base entries on actual validation and constructor errors. Link to `docs/config.md` for fixes. Avoid speculative upstream outages beyond generic HTTP/source errors unless tests or code reveal specific behavior.
+
+### `docs/policy/development.md`
+
+Use `docs/policy/architecture.md` as the authority. Give concrete safe-change steps for adding source drivers, normalizers, schemas, Postgres tables, config examples, and docs. Avoid repeating the architecture policy wholesale.
+
+### `docs/internal/*.md`
+
+Create concise component docs. They should guide changes, not become manuals. Each should include tests to inspect before changing. Link to package docs when those are more precise.
+
+### `docs/integrations/*.md`
+
+Document only external contracts actually used by the implementation. Keep provider docs narrow and maintenance-oriented. Do not describe unimplemented SPC support outside `docs/roadmap/spc.md`.
+
+### Package comments
+
+Fix stale path and future-language comments during the documentation migration stage that touches developer docs. Specific likely fixes:
+
+- `model/doc.go`: remove “stdout today; others later.”
+- `standards/doc.go`: correct `internal/standards/doc.go` path.
+- `internal/normalizers/doc.go`: correct `internal/standards/schema.go` path.
+- `internal/providers/openweather/doc.go`: remove “forecasts/alerts later.”
+
+## Examples Plan
+
+No `examples/` directory currently exists. Create one because the project has non-trivial configuration and operator workflows.
+
+Recommended examples:
+
+- `examples/config.minimal.yml`: one public HTTP source, stdout sink, route. Validity check: `config.Load` in a new or existing config/example test. Link from README, config, CLI.
+- `examples/config.nats.yml`: NATS sink publishing example. Validity check: `config.Load`; do not require a live NATS server. Link from config and operations.
+- `examples/config.postgres.yml`: Postgres sink with placeholder credentials and optional `prune`. Validity check: `config.Load`; do not require a live Postgres server. Link from config, operations, Postgres integration docs.
+- `examples/config.full.yml`: optional, only if the team wants one annotated config covering all implemented drivers. Validity check: `config.Load`; must use placeholders for secrets and avoid real OpenWeather API keys. Link from config docs only.
+
+Do not add SPC examples until SPC support is implemented.
+
+## Internal Documentation Plan
+
+### Runtime Pipeline
+
+- Path: `docs/internal/runtime.md`
+- Purpose: explain daemon composition.
+- Inputs and outputs: YAML config in; feed events through scheduler/pipeline/dispatcher to sinks out.
+- Boundaries: composition belongs in `cmd/weatherfeeder`; domain mapping belongs in normalizers/model.
+- Config fields used: sources, sinks, routes, source `every`, mode/kinds, sink params.
+- Adapters used: feedkit scheduler, processors, dispatch, sinks.
+- Failure behavior: fatal startup errors; runtime errors logged and cancel context; interrupt/SIGTERM shutdown.
+- Tests to inspect: `cmd/weatherfeeder/main_test.go`, feedkit scheduler/dispatch tests.
+- Invariants: normalize before dedupe; bounded event channel; context-aware shutdown.
+
+### Sources
+
+- Path: `docs/internal/sources.md`
+- Purpose: document source driver architecture.
+- Inputs and outputs: `config.SourceConfig` and upstream HTTP responses in; raw feed events out.
+- Boundaries: sources fetch and envelope raw payloads; normalizers decode full payloads.
+- Config fields used: name, driver, mode, every, kinds, params URL/user agent/HTTP options.
+- Adapters used: feedkit source registry and HTTP helper.
+- Failure behavior: constructor validation, HTTP errors, unchanged 304 returns no events, some malformed metadata still emits raw events.
+- Tests to inspect: `internal/sources/builtins_test.go`, provider source tests.
+- Invariants: drivers registered in one place; raw schemas from `standards`; no canonical mapping in sources.
+
+### Normalizers
+
+- Path: `docs/internal/normalizers.md`
+- Purpose: document raw-to-canonical mapping architecture.
+- Inputs and outputs: raw events matched by schema in; canonical model payload events out.
+- Boundaries: no HTTP, no sink persistence, no CLI/config behavior.
+- Config fields used: none directly.
+- Adapters used: feedkit normalize processor.
+- Failure behavior: decode/parse/missing required fields return contextual errors; no-match passthrough configured in main.
+- Tests to inspect: `internal/normalizers/builtins_test.go`, provider normalizer tests, `internal/normalizers/common` tests.
+- Invariants: schema matching only, stable registration order, canonical schema constants.
+
+### Postgres Sink Mapping
+
+- Path: `docs/internal/postgres-sink.md`
+- Purpose: document weatherfeeder-specific Postgres mapping internals.
+- Inputs and outputs: canonical events in; feedkit `PostgresWrite` rows out.
+- Boundaries: mapper validates and maps; feedkit owns DB connection, DDL, transactions, pruning.
+- Config fields used: sink `uri`, `username`, `password`, optional `prune` via feedkit.
+- Adapters used: feedkit Postgres sink.
+- Failure behavior: unsupported schemas map to no writes or errors per mapper behavior; required missing fields fail before write.
+- Tests to inspect: `internal/sinks/postgres/map_test.go`, `schema_test.go`, feedkit Postgres tests.
+- Invariants: consume canonical schemas only; preserve envelope columns; keep parent/child order indexes.
+
+## Integration Documentation Plan
+
+### Event Wire Contract
+
+- Path: `docs/integrations/events.md`
+- External system or contract: JSON events emitted to stdout/NATS and represented in Postgres parent envelope columns.
+- Current usage: sinks marshal feedkit events or map canonical events to tables.
+- Version notes: schema identifiers use `raw.*.v1` and `weather.*.v1`; JSON tags are compatibility contract.
+- Document: actual envelope fields, schema list, payload fields, units, optionality, examples.
+- Do not document: weatherapi HTTP endpoints, unimplemented outlooks, or future schemas.
+
+### Postgres
+
+- Path: `docs/integrations/postgres.md`
+- External system or contract: PostgreSQL schema created/written by feedkit Postgres sink using weatherfeeder schema definition.
+- Current usage: optional configured sink; create-if-missing tables and indexes; transactional writes; optional pruning.
+- Version notes: no migration framework is implemented; existing DBs may need manual schema changes when table definitions change.
+- Document: params, table contract, pruning, reconstruction, migration caveats.
+- Do not document: weatherapi query behavior except as a downstream consumer link if needed.
+
+### NWS
+
+- Path: `docs/integrations/nws.md`
+- External system or contract: NWS API and NWS forecast discussion/weather story endpoints used by current drivers.
+- Current usage: observations, alerts, hourly forecast, narrative forecast, forecast discussion, weather stories.
+- Version notes: no explicit upstream API version in code; weatherfeeder pins its own raw schema names.
+- Document: endpoint shapes used, required User-Agent, accept headers, effective time, raw schemas.
+- Do not document: SPC outlooks or unsupported NWS products.
+
+### Open-Meteo
+
+- Path: `docs/integrations/openmeteo.md`
+- External system or contract: Open-Meteo forecast API for current observations and hourly forecasts.
+- Current usage: JSON HTTP source, time parsing from timezone/UTC offset, hourly fields mapped to canonical forecast.
+- Version notes: no explicit upstream API version in code.
+- Document: required URL/user agent params, expected current/hourly response pieces, effective time behavior.
+- Do not document: daily forecast unless implemented.
+
+### OpenWeather
+
+- Path: `docs/integrations/openweather.md`
+- External system or contract: OpenWeather current weather endpoint.
+- Current usage: observation source/normalizer only.
+- Version notes: source requires `units=metric` in URL.
+- Document: metric units requirement, timestamp behavior, mapped fields, secret handling for API key.
+- Do not document: OpenWeather forecasts or alerts.
+
+### NATS
+
+- Path: include in `docs/operations.md` and `docs/config.md`; create `docs/integrations/nats.md` only if NATS-specific maintenance grows.
+- External system or contract: NATS publish subject configured by feedkit sink.
+- Current usage: optional sink publishes each event as JSON.
+- Document: `url`, `subject`, JSON event payload, connection failure behavior.
+- Do not document: subscriptions or server administration beyond this sink contract.
+
+## Recommended Implementation Sequence
+
+### Stage 1: Current-State README, CLI, and Config Docs
+
+- Goal: establish accurate user/operator entry points.
+- Files to create/update/delete/move: rewrite `README.md`; create `docs/cli.md`; create `docs/config.md`.
+- Repository areas to inspect: `cmd/weatherfeeder/main.go`, `cmd/weatherfeeder/config.yml`, `../feedkit/config`, `../feedkit/sources/http.go`, `../feedkit/sinks`, `internal/sources/builtins.go`, source constructors.
+- Acceptance criteria: README concise and current; CLI doc states no flags and cwd `config.yml`; config doc includes complete implemented config reference and no secrets.
+- Suggested validation commands: `go test ./cmd/weatherfeeder`; `rg -n "only implemented sink|current MVP|--config|API.md" README.md docs/cli.md docs/config.md`.
+- Size: small enough for one implementation prompt.
+
+### Stage 2: Event and Postgres Integration Contracts
+
+- Goal: move and correct external contracts.
+- Files to create/update/delete/move: create `docs/integrations/events.md`; create `docs/integrations/postgres.md`; delete or replace `API.md` with a pointer; update links in `README.md` and `docs/policy/architecture.md`.
+- Repository areas to inspect: `../feedkit/event/event.go`, `standards/schema.go`, `model/*.go`, `internal/sinks/postgres/doc.go`, `schema.go`, `map.go`, normalizer tests, sink tests.
+- Acceptance criteria: event envelope field names match code; all current schemas listed; Postgres contract matches schema definition; no duplicate or stale API rows.
+- Suggested validation commands: `go test ./internal/sinks/postgres ./internal/normalizers/...`; `rg -n "effectiveAt|emittedAt|API.md|response \| string.*response" README.md docs API.md`.
+- Size: one implementation prompt if kept focused; split if examples are expanded heavily.
+
+### Stage 3: Operations and Troubleshooting Docs
+
+- Goal: document running and recovering the daemon.
+- Files to create/update/delete/move: create `docs/operations.md`; create `docs/troubleshooting.md`.
+- Repository areas to inspect: `cmd/weatherfeeder/main.go`, `Dockerfile`, feedkit scheduler/dispatch/source/sink implementations, config validation, source/sink constructors.
+- Acceptance criteria: operational docs describe logs, shutdown, scheduling, conditional HTTP, fanout, Postgres create/prune behavior, and common failures without inventing commands.
+- Suggested validation commands: `go test ./cmd/weatherfeeder`; `rg -n "TODO|future|planned|unimplemented" docs/operations.md docs/troubleshooting.md`.
+- Size: small enough for one implementation prompt.
+
+### Stage 4: Examples Directory and Example Validation
+
+- Goal: add maintained copyable configs.
+- Files to create/update/delete/move: create `examples/config.minimal.yml`, `examples/config.nats.yml`, `examples/config.postgres.yml`; optionally create `examples/config.full.yml`; update tests to load examples; update links in README/config/operations.
+- Repository areas to inspect: `cmd/weatherfeeder/config.yml`, `cmd/weatherfeeder/main_test.go`, feedkit config validation, source/sink params.
+- Acceptance criteria: examples contain no secrets, load successfully, and are linked from canonical docs.
+- Suggested validation commands: `go test ./cmd/weatherfeeder`; `rg -n "appid=|password: [^<]|token|secret" examples cmd/weatherfeeder/config.yml docs`.
+- Size: one implementation prompt.
+
+### Stage 5: Developer and Internal Docs
+
+- Goal: document safe change workflow and internal component boundaries.
+- Files to create/update/delete/move: create `docs/policy/development.md`; create `docs/internal/runtime.md`; create `docs/internal/sources.md`; create `docs/internal/normalizers.md`; create `docs/internal/postgres-sink.md`; lightly update package comments with stale paths/future language.
+- Repository areas to inspect: architecture policy, package docs, registries, source/normalizer/sink tests, `go.mod`.
+- Acceptance criteria: docs are inward-facing, concise, and action-oriented; package comments no longer contain stale path or future-support language outside roadmap.
+- Suggested validation commands: `go test ./...`; `rg -n "internal/standards|others later|forecasts/alerts later|future expensive steps" . -g '*.go' -g '*.md'`.
+- Size: likely one implementation prompt, but split package-comment cleanup if code comment edits are considered too broad.
+
+### Stage 6: Provider Integration Notes
+
+- Goal: document external provider contracts actually used by implemented source/normalizer pairs.
+- Files to create/update/delete/move: create `docs/integrations/nws.md`, `docs/integrations/openmeteo.md`, `docs/integrations/openweather.md`; optionally create `docs/integrations/nats.md` only if NATS content should stand alone.
+- Repository areas to inspect: provider source packages, provider normalizer packages, `internal/providers`, provider tests/fixtures.
+- Acceptance criteria: each integration doc is narrow, current, and excludes unimplemented products; NWS doc does not include SPC outlooks except linking to roadmap if needed.
+- Suggested validation commands: `go test ./internal/sources/... ./internal/normalizers/... ./internal/providers/...`; `rg -n "SPC|outlook|daily forecast|OpenWeather forecast|OpenWeather alert" docs/integrations`.
+- Size: one implementation prompt.
+
+### Stage 7: Final Documentation Consistency Pass
+
+- Goal: remove stale references and verify policy compliance.
+- Files to create/update/delete/move: any docs touched in prior stages; remove obsolete root `API.md` if not kept as pointer.
+- Repository areas to inspect: whole documentation tree, package comments, tests.
+- Acceptance criteria: every non-roadmap doc describes implemented behavior only; every doc has clear audience/scope; roadmap content remains only in `docs/roadmap`; links resolve by inspection.
+- Suggested validation commands: `go test ./...`; `find docs -type f -name '*.md' -print | sort`; `rg -n "MVP|only implemented sink|planned|future|later|deprecated|experimental|TODO|API.md|effectiveAt|emittedAt|internal/standards|appid=" README.md docs internal model standards cmd examples`.
+- Size: small enough for one implementation prompt.
+
+## Validation Plan
+
+Automated checks available now:
+
+- `go test ./...` verifies code behavior and existing load-tested sample config.
+- `go test ./cmd/weatherfeeder` verifies `cmd/weatherfeeder/config.yml` loads and sources build scheduler jobs.
+- Focused package tests verify source drivers, normalizers, and Postgres schema/mapping.
+
+Recommended new checks during implementation:
+
+- Add tests that load all `examples/*.yml` with `feedkit/config.Load`.
+- Add or extend tests to ensure documented source drivers in config examples build through `internal/sources.RegisterBuiltins`.
+- Use `rg` checks for stale or prohibited terms: `only implemented sink`, `current MVP`, `future`, `later`, `planned`, `deprecated`, `experimental`, `API.md`, `effectiveAt`, `emittedAt`, `internal/standards`, and secret-like strings such as `appid=`.
+- Manually verify Markdown links because no dedicated Markdown/link checker is currently present.
+- Manually compare `docs/integrations/events.md` against `../feedkit/event/event.go`, `standards/schema.go`, and `model/*.go` before accepting.
+- Manually compare `docs/integrations/postgres.md` against `internal/sinks/postgres/schema.go` before accepting.
+
+No repository-local Markdown formatter, Markdown linter, Makefile, justfile, Taskfile, or `package.json` docs tooling was found during this planning pass.
+
+## Open Questions
+
+No question blocks implementation of this documentation migration. Recommended decisions:
+
+- Move the canonical event contract from `API.md` to `docs/integrations/events.md` to comply with the documentation policy.
+- Replace root `API.md` with a short pointer only if backward-compatible links are considered important; otherwise delete it during the migration.
+- Keep `cmd/weatherfeeder/config.yml` as the executable in-repo sample used by tests, but create public copyable examples under `examples/` and remove secret-like values from examples.

+# SPC Convective Outlook Support Roadmap
+
+## Summary
+
+Add `weatherfeeder` support for Storm Prediction Center convective outlooks as a new canonical outlook domain. The feature should poll SPC GeoJSON outlook products, optionally enrich them with RSS discussion metadata, compute whether the configured forecast point is inside each active outlook polygon, normalize the result into a provider-independent schema, and persist it through existing sinks.
+
+This is a new domain, not an extension of `weather.alert.v1`. SPC outlooks describe probabilistic/categorical risk areas over a validity window; alerts describe active actionable hazard messages.
+
+## Public Contract
+
+Add schema constants:
+
+- Raw schema: `raw.spc.convective_outlook.v1`
+- Canonical schema: `weather.outlook.v1`
+
+Add source driver:
+
+- `spc_convective_outlook`
+
+Add event kind:
+
+- `outlook`
+
+Add canonical model types:
+
+- `model.WeatherOutlookRun`
+- `model.WeatherOutlook`
+
+Recommended canonical run fields:
+
+- `locationId`, `locationName`
+- `latitude`, `longitude`
+- `asOf`
+- `issuedAt`
+- `outlooks`
+
+Recommended canonical outlook fields:
+
+- `id`
+- `provider`
+- `product`
+- `day`
+- `outlookType`
+- `label`
+- `labelText`
+- `severityRank`
+- `validFrom`
+- `validTo`
+- `issuedAt`
+- `expiresAt`
+- `forecaster`
+- `headline`
+- `summary`
+- `discussion`
+- `sourceUrl`
+- `imageUrl`
+- `containsLocation`
+- `geometry`
+
+Contract defaults:
+
+- `product` should be `convective`.
+- `outlookType` should be one of `categorical`, `tornado`, `hail`, `wind`.
+- `day` should be `1`, `2`, or `3` for this first implementation.
+- `containsLocation` is computed against configured forecast coordinates.
+- `geometry` should preserve compact GeoJSON geometry for auditability and future API use.
+
+## Source Scope
+
+The source should fetch a bundle of SPC products in one poll cycle and emit one raw event containing the fetched RSS metadata, GeoJSON products, configured point, and per-product fetch metadata.
+
+Poll these GeoJSON URLs:
+
+- `https://www.spc.noaa.gov/products/outlook/day1otlk_cat.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day1otlk_torn.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day1otlk_hail.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day1otlk_wind.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day2otlk_cat.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day2otlk_torn.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day2otlk_hail.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day2otlk_wind.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day3otlk_cat.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day3otlk_torn.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day3otlk_hail.nolyr.geojson`
+- `https://www.spc.noaa.gov/products/outlook/day3otlk_wind.nolyr.geojson`
+
+Note: the initial candidate list duplicated Day 3 wind and omitted Day 2 wind. Use the corrected 12-product matrix above.
+
+Also poll:
+
+- `https://www.spc.noaa.gov/products/spcacrss.xml`
+
+RSS usage:
+
+- Use RSS as discussion/discovery metadata, not as the geometry source.
+- Preserve item title, link, description text, pubDate, and guid where useful.
+- Extract the narrative outlook text from the RSS item description when practical.
+- Do not attempt to parse polygons from RSS HTML.
+
+Polling cadence:
+
+- Use a default cadence of `30m`, not daily/twice-daily. SPC current outlook files can update several times per day, and a 30-minute poll with HTTP caching is low cost and less likely to miss updates.
+- Rely on ETag/Last-Modified handling from the HTTP source layer where available.
+- Keep the cadence configurable via `every`.
+
+Recommended config shape:
+
+```yaml
+- name: SPCConvectiveOutlookSTL
+  mode: poll
+  kinds: ["outlook"]
+  driver: spc_convective_outlook
+  every: 30m
+  params:
+    latitude: 38.6239
+    longitude: -90.3571
+    location_id: "stl"
+    location_name: "St. Louis, MO"
+    user_agent: "HomeOps (eric@maximumdirect.net)"
+```
+
+The source should own default SPC URLs, with optional params to override the RSS URL and product URLs for tests or future provider changes.
+
+## Implementation Stages
+
+### Stage 1: Raw Source and Schema
+
+- Add schema constants and model placeholders.
+- Add `internal/sources/spc` package.
+- Implement `spc_convective_outlook` as a poll source.
+- Fetch all configured GeoJSON products and RSS during a poll cycle.
+- Emit one raw event with kind `outlook` and schema `raw.spc.convective_outlook.v1`.
+- Use the latest valid `ISSUE_ISO`, RSS `lastBuildDate`, or fetch time for `effectiveAt`, in that order.
+- Preserve partial fetch errors as source errors for the first implementation; do not emit incomplete outlook bundles unless a later explicit degraded-mode policy is added.
+
+Tests:
+
+- source driver builds as a `PollSource`
+- source advertises kind `outlook`
+- source emits one raw bundled event
+- source chooses expected effective time
+- source uses configured location metadata
+- source fails clearly on missing latitude/longitude
+
+### Stage 2: GeoJSON and Spatial Matching
+
+- Add an internal geometry helper package, for example `internal/geo`.
+- Support GeoJSON `Polygon` and `MultiPolygon`.
+- Implement point-in-polygon with ring support:
+  - first ring is the exterior
+  - subsequent rings are holes
+  - boundary counts as inside
+  - GeoJSON coordinate order is `[longitude, latitude]`
+- Use planar ray casting for this operational point-in-polygon check.
+
+Tests:
+
+- point inside polygon
+- point outside polygon
+- point on polygon boundary
+- point inside a hole is outside
+- point inside one multipolygon member is inside
+- longitude/latitude order regression test
+
+### Stage 3: Normalizer and Canonical Mapping
+
+- Add `SPCConvectiveOutlookNormalizer`.
+- Match only `raw.spc.convective_outlook.v1`.
+- Decode the raw source bundle.
+- Map each GeoJSON feature to one `WeatherOutlook`.
+- Preserve SPC feature order within each product, then order products by day and type.
+- Map properties:
+  - `VALID_ISO` -> `validFrom`
+  - `EXPIRE_ISO` -> `validTo` and `expiresAt`
+  - `ISSUE_ISO` -> `issuedAt`
+  - `FORECASTER` -> `forecaster`
+  - `LABEL` -> `label`
+  - `LABEL2` -> `labelText`
+  - `DN` -> `severityRank`
+- Derive:
+  - `day` from product key or URL
+  - `outlookType` from product key or URL
+  - `id` from day, type, label, issuedAt, validFrom, and feature index
+  - `containsLocation` from configured point and GeoJSON geometry
+- Enrich narrative fields from RSS where a matching day/product item can be determined.
+- Set run `asOf` to the latest valid `issuedAt` across features, falling back to RSS `lastBuildDate`, then input event time.
+- Set run `issuedAt` to the latest valid `issuedAt` across features.
+- Set output event `effectiveAt` to run `asOf`.
+
+Tests:
+
+- normalizer routes only raw SPC schema
+- categorical and probabilistic products map expected fields
+- `containsLocation` is true for a known point inside a fixture polygon
+- `containsLocation` is false outside
+- missing optional RSS still permits GeoJSON normalization
+- malformed required GeoJSON timestamps fail with useful context
+- canonical JSON shape does not expose raw-provider-only bundle internals
+
+### Stage 4: Postgres Sink
+
+Add tables:
+
+- `outlook_runs`
+- `outlooks`
+
+Suggested `outlook_runs` columns:
+
+- event envelope columns
+- `location_id`
+- `location_name`
+- `latitude`
+- `longitude`
+- `as_of`
+- `issued_at`
+- `outlook_count`
+
+Suggested `outlooks` columns:
+
+- `run_event_id`
+- `outlook_index`
+- `as_of`
+- `product`
+- `day`
+- `outlook_type`
+- `label`
+- `label_text`
+- `severity_rank`
+- `valid_from`
+- `valid_to`
+- `issued_at`
+- `expires_at`
+- `forecaster`
+- `headline`
+- `summary`
+- `discussion`
+- `source_url`
+- `image_url`
+- `contains_location`
+- `geometry_json`
+
+Suggested indexes:
+
+- `outlook_runs(location_id, as_of)`
+- `outlooks(contains_location, valid_from, valid_to)`
+- `outlooks(day, outlook_type, label)`
+- `outlooks(valid_from, valid_to)`
+
+Mapping rules:
+
+- Store `geometry` as compact GeoJSON text in `geometry_json`.
+- Require run `asOf`.
+- Require outlook `validFrom`, `validTo`, `issuedAt`, `day`, `outlookType`, and `label`.
+- Preserve all outlook polygons, not only polygons containing the configured point.
+
+Tests:
+
+- schema includes outlook tables and indexes
+- mapper writes one run row plus one row per outlook
+- mapper stores compact geometry JSON
+- mapper rejects missing required run/outlook fields
+
+### Stage 5: Config and Documentation
+
+- Update sample config with `SPCConvectiveOutlookSTL`.
+- Add `outlook` to route examples.
+- Update README provider capabilities.
+- Update `API.md` with `weather.outlook.v1`.
+- Update Postgres sink docs with outlook table contract.
+
+Docs should clearly state:
+
+- RSS is used for narrative/discussion metadata.
+- GeoJSON is used for polygons and point matching.
+- `containsLocation` is computed by weatherfeeder at ingestion time.
+- Geometry is stored for downstream audit/display.
+
+### Stage 6: Weatherapi Follow-Up
+
+Do not include weatherapi changes in the first weatherfeeder implementation unless explicitly requested.
+
+Likely future weatherapi endpoints:
+
+- `GET /outlooks/convective`
+- `GET /outlooks/convective/active`
+- `GET /outlooks/convective/location`
+
+Recommended API behavior:
+
+- latest run by default
+- active outlooks filtered by current time and `containsLocation=true`
+- optional filter query params for `day`, `outlookType`, and `containsLocation`
+
+## Open Questions for Implementation
+
+- Whether to include Day 4-8 probabilistic outlooks in a later version. Exclude them from v1.
+- Whether to make partial source bundles acceptable if one product URL fails. Default v1 behavior should fail the poll and retry.
+- Whether to parse detailed discussion text from RSS only, HTML pages, or both. Default v1 should use RSS only.
+- Whether to keep `geometry` in canonical JSON permanently. Default v1 should include it because it preserves source context and enables downstream display.
+
+## Verification Commands
+
+Run focused tests:
+
+```sh
+go test ./internal/sources ./internal/normalizers/... ./internal/sinks/postgres ./model
+```
+
+Run full weatherfeeder tests:
+
+```sh
+go test ./...
+```
+
+## Acceptance Criteria
+
+- A configured SPC source emits raw outlook bundles.
+- Normalization produces `weather.outlook.v1` events.
+- Each outlook indicates whether the configured forecast point is inside its polygon.
+- All current Day 1-3 categorical/tornado/hail/wind products are represented.
+- RSS discussion metadata is preserved where available.
+- Postgres sink persists outlook runs and outlook rows.
+- Sample config and public docs describe the new kind, driver, schema, and storage contract.

+# Troubleshooting
+
+Use this guide with [configuration](config.md) and [operations](operations.md).
+Messages are emitted through the standard logger on stderr.
+
+## `config load failed: ... read "config.yml"`
+
+Symptom: startup exits before building sources or sinks.
+
+Likely cause: the process working directory does not contain `config.yml`, or
+the runtime user cannot read it.
+
+Diagnostic: run `pwd` in the same working directory used by the process, then
+check `ls -l config.yml`.
+
+Safe fix: place the intended config at `./config.yml`, change the working
+directory, or mount the file at `/weatherfeeder/config.yml` when using the
+provided container image.
+
+## `config load failed: ... parse YAML`
+
+Symptom: startup exits with a YAML parse error or an unknown field error.
+
+Likely cause: invalid YAML syntax, multiple YAML documents, or a misspelled
+config struct field.
+
+Diagnostic: inspect the line and field in the error. Feedkit uses strict YAML
+field decoding for config struct fields.
+
+Safe fix: correct the YAML and compare the shape with
+[configuration](config.md). Driver-specific `params` keys are validated by their
+source or sink constructors.
+
+## `config validation failed`
+
+Symptom: startup exits and prints one or more validation messages.
+
+Likely cause: missing `sources` or `sinks`, blank names, duplicate source or sink
+names, invalid `mode`, missing `every` for a polling source with `mode: poll`, or
+a route that references an unknown sink.
+
+Diagnostic: read every bullet under `config validation failed`; the loader sorts
+these messages so multiple issues can be fixed in one edit.
+
+Safe fix: update the top-level config fields as documented in
+[configuration](config.md).
+
+## `unknown source driver`
+
+Symptom: startup exits with `build source failed`.
+
+Likely cause: `sources[].driver` does not match a registered weatherfeeder
+source driver.
+
+Diagnostic: compare the configured driver with the source driver table in
+[configuration](config.md#source-drivers).
+
+Safe fix: correct the driver name. Current drivers include `nws_observation`,
+`nws_alerts`, `nws_forecast_hourly`, `nws_forecast_narrative`,
+`nws_forecast_discussion`, `nws_weatherstories`, `openmeteo_observation`,
+`openmeteo_forecast`, and `openweather_observation`.
+
+## `unknown sink driver`
+
+Symptom: startup exits with `build sink failed`.
+
+Likely cause: `sinks[].driver` is not registered.
+
+Diagnostic: compare the configured driver with the sink driver table in
+[configuration](config.md#sink-drivers).
+
+Safe fix: use `stdout`, `nats`, or `postgres`.
+
+## `source expected kinds validation failed`
+
+Symptom: startup exits after building a source.
+
+Likely cause: `sources[].kinds` declares a kind the source does not emit.
+
+Diagnostic: compare the configured `kinds` list with the source driver kind in
+[configuration](config.md#source-drivers).
+
+Safe fix: remove `kinds` or set it to the kind emitted by that driver.
+
+## `params.url is required` Or `params.user_agent is required`
+
+Symptom: startup exits with `build source failed`.
+
+Likely cause: a source is missing required HTTP params, or the values are blank
+or not strings.
+
+Diagnostic: inspect the named source in the error and check its `params`.
+
+Safe fix: add non-empty `url` and `user_agent` values. See
+[HTTP source params](config.md#http-source-params).
+
+## `url must include units=metric`
+
+Symptom: startup exits for an `openweather_observation` source.
+
+Likely cause: the OpenWeather URL omits `units=metric` or sets another unit
+system.
+
+Diagnostic: inspect the query string in `params.url`.
+
+Safe fix: add `units=metric` to the OpenWeather current-weather URL. Keep API
+keys out of committed configs.
+
+## `source ... sources[].every must be > 0 for polling sources`
+
+Symptom: startup exits while building scheduler jobs.
+
+Likely cause: a current weatherfeeder polling source has no usable `every`
+interval.
+
+Diagnostic: inspect the named `sources[]` entry and check `every`.
+
+Safe fix: set a positive duration such as `1m`, `10m`, or `1h`.
+
+## `build sink failed ... params.url is required`
+
+Symptom: startup exits while building a NATS sink.
+
+Likely cause: the NATS sink is missing `params.url`, or the value is blank or
+not a string.
+
+Diagnostic: inspect the named sink in the error and check its `params`.
+
+Safe fix: set a NATS URL such as `nats://localhost:4222`.
+
+## `build sink failed ... params.subject is required`
+
+Symptom: startup exits while building a NATS sink.
+
+Likely cause: the NATS sink is missing `params.subject`, or the value is blank
+or not a string.
+
+Diagnostic: inspect the named sink in the error and check its `params`.
+
+Safe fix: set a non-empty subject such as `weatherfeeder`.
+
+## `dispatch: sink ... failed consuming event ... NATS sink: connect`
+
+Symptom: the daemon starts, but NATS events are not published.
+
+Likely cause: the NATS server URL is unreachable, the server is not accepting
+connections, or the configured URL is wrong for the runtime network.
+
+Diagnostic: from the same runtime environment, check that the host and port in
+`sinks[].params.url` are reachable.
+
+Safe fix: correct the NATS URL or restore broker connectivity. Other configured
+sinks continue receiving events.
+
+## `postgres sink ... open db`
+
+Symptom: startup exits while building a Postgres sink.
+
+Likely cause: the database URI, username, password, network path, or database
+availability is wrong.
+
+Diagnostic: inspect `sinks[].params.uri`, `username`, and `password`; verify
+that the same runtime environment can reach the database.
+
+Safe fix: correct the credentials or URI, restore database connectivity, then
+restart the daemon.
+
+## `postgres sink ... ensure table` Or `ensure index`
+
+Symptom: startup exits during Postgres initialization.
+
+Likely cause: the database user cannot create required tables or indexes, an
+existing object conflicts with weatherfeeder's expected table contract, or the
+database is unavailable during initialization.
+
+Diagnostic: inspect the named table or index in the error and compare existing
+database objects with the [Postgres table contract](integrations/postgres.md).
+
+Safe fix: grant the needed database privileges, create a compatible schema, or
+perform an operator-managed migration before restarting.
+
+## `postgres sink: insert into ...`
+
+Symptom: the daemon starts, but Postgres writes for some events fail.
+
+Likely cause: a duplicate primary key, incompatible existing table definition,
+database constraint error, or connection failure during a write transaction.
+
+Diagnostic: inspect the table name and database error in the log. Compare the
+table with [Postgres integration](integrations/postgres.md).
+
+Safe fix: repair the database schema or address the duplicate/connection issue.
+Other configured sinks continue receiving events.
+
+## No Events Appear On A Sink
+
+Symptom: the daemon is running but the expected sink receives no events.
+
+Likely cause: the route does not match the event kind, the source has not
+emitted changed content, or the sink is failing per event.
+
+Diagnostic: check `routes`, source `kinds`, and logs for `scheduler: poll
+failed`, `dispatcher: pipeline error`, or `dispatch: sink ... failed consuming
+event`.
+
+Safe fix: correct the route or source configuration. If the source uses
+conditional HTTP and the upstream has not changed, no event is emitted for a
+`304 Not Modified` response; wait for changed upstream content or temporarily
+set `params.conditional: false` for diagnosis.
+
+## `scheduler: poll failed`
+
+Symptom: one source logs poll failures while the daemon keeps running.
+
+Likely cause: upstream HTTP error, bad URL, timeout, response body limit, or
+provider response shape that the source cannot parse.
+
+Diagnostic: inspect the source name in the log and review its HTTP params.
+
+Safe fix: correct the URL, user agent, timeout, or body limit. The next
+scheduled poll will retry.
+
+## `dispatcher: pipeline error`
+
+Symptom: source polling succeeds, but one event is dropped before sinks.
+
+Likely cause: a normalizer could not decode or map the raw payload, or dedupe
+received an invalid event ID.
+
+Diagnostic: inspect the error text and the source/schema that produced the
+event. Review the [event wire contract](integrations/events.md) for expected
+canonical fields.
+
+Safe fix: correct source configuration if it points to the wrong upstream
+product. If the upstream payload changed shape, update the relevant normalizer
+and tests.
