+# Near-Term Report Implementation Roadmap
+
+## Purpose
+
+This roadmap defines the concrete implementation sequence for
+`docs/roadmap/near-term.md`. It is written for an LLM coding agent that will
+implement each stage in order.
+
+This is a future-work roadmap. Until a stage is implemented, non-roadmap docs
+must not describe `near_term` behavior as available.
+
+## Source Feature Roadmap
+
+Use `docs/roadmap/near-term.md` as the authoritative feature roadmap for user
+intent, target behavior, and policy choices. This document is the implementation
+plan. If the target behavior changes, update `near-term.md` first, then update
+this roadmap.

+## Locked Implementation Decisions

+- Add report ID `near_term` and Go constant `report.NearTerm`.
+- Add CLI command `weatherreporter generate near-term`.
+- Do not add `--date`, `--start`, `--end`, or duration flags for this report.
+- Do not add `near_term` to morning or evening batches in the first
+  implementation.
+- Define the valid-period duration with a package-owned constant, initially
+  `6` hours.
+- Resolve the valid period as `[generation_time, generation_time + 6h)` in the
+  effective report timezone.
+- Use prompt ID `weather.near_term_report`.
+- Use artifact group `near-term` and batch output name `near-term.md`.
+- Add comparison strategy constant `CompareRollingWindow = "rolling_window"`.
+- Declare `CompatiblePriorIDs: []report.ID{report.NearTerm}`, but do not emit
+  Recent Changes for `near_term` in the first implementation.
+- Keep state prior lookup returning `nil` for rolling-window reports until a
+  future comparison algorithm is designed.
+- Default module order is:
+  1. `metadata`
+  2. `current_conditions`
+  3. `hourly_forecast`
+  4. `precip_timing`
+  5. `alert_digest`
+  6. `spc_convective_outlooks`
+  7. `area_forecast_discussion`
+  8. `spc_convective_discussion`
+  9. `weather_story`
+- Configure the near-term `area_forecast_discussion` module with only
+  `key_messages` and `short_term` sections.
+- Do not include daily/daypart modules in the default near-term composition.
+- Alert and SPC modules must use existing valid-period overlap behavior.
+- Preserve existing public behavior for all current report types.
+
+## Stage 1: Report Identity And Period Resolution
+
+Goal: add the `near_term` report definition, constants, registry entry, and
+rolling six-hour valid-period resolver.
+
+Files to inspect:
+
+- `internal/report/definition.go`
+- `internal/report/registry.go`
+- `internal/report/period.go`
+- `internal/report/daily_report.go`
+- `internal/report/period_test.go`
+- `internal/state/filesystem.go`
+
+Implementation:
+
+- Add `NearTerm ID = "near_term"` in `internal/report/definition.go`.
+- Add `CompareRollingWindow ComparisonStrategy = "rolling_window"`.
+- Add `internal/report/near_term_report.go`.
+- Define a package-local duration constant in that file, for example:
+
+  ```go
+  const nearTermHours = 6
+  ```
+
+- Add `nearTermDefinition()` returning:
+  - `ID: NearTerm`
+  - `Name: "Near-Term Report"`
+  - `PromptID: "weather.near_term_report"`
+  - `ComparisonStrategy: CompareRollingWindow`
+  - `ArtifactGroup: "near-term"`
+  - `BatchOutputName: "near-term.md"`
+  - `Generated: true`
+  - `CompatiblePriorIDs: []ID{NearTerm}`
+  - `Modules: nearTermModules()`
+  - no `Morning` or `Evening` membership
+  - `resolve: resolveNearTerm`
+- Implement `resolveNearTerm` as generation-time anchored:
+
+  ```go
+  localNow := req.Now.In(req.Location)
+  return timeutil.Period{
+      Start: localNow,
+      End:   localNow.Add(nearTermHours * time.Hour),
+  }, nil
+  ```
+
+- Add `nearTermDefinition()` to `DefaultRegistry()`.
+- Add `NearTerm` to `Registry.All()` in a stable order after
+  `DailyTomorrow` and before `ThreeDay`.
+- Do not change `BatchReports`.
+- Leave `state.FindPriorSnapshot` behavior unchanged for
+  `CompareRollingWindow`; it should return `nil` because it only supports
+  same-date and weekend lookup.
+
+Tests:
+
+- Add report period tests for:
+  - lookup succeeds for `NearTerm`;
+  - `Registry.All()` includes `NearTerm`;
+  - fixed generation time resolves to exactly six hours;
+  - timezone-aware start and end use the effective location;
+  - valid period is not civil-day truncated;
+  - metadata RunID includes `near_term`;
+  - batch membership remains unchanged.
+- Update registry metadata/path tests to include:
+  - artifact group `near-term`;
+  - batch output name `near-term.md`;
+  - generated `true`;
+  - compatible prior IDs `[]ID{NearTerm}`;
+  - comparison strategy `CompareRollingWindow`.
+
+Validation:
+
+```bash
+go test ./internal/report ./internal/state
+```
+
+This stage is small enough for one implementation prompt.
+
+## Stage 2: Module Compatibility And Default Composition
+
+Goal: make existing modules compatible with `near_term` where appropriate and
+declare the default module composition.
+
+Files to inspect:
+
+- `internal/report/near_term_report.go`
+- `internal/briefing/modules.go`
+- `internal/module/module.go`
+- `internal/briefing/modules_test.go`
+- `internal/briefing/base_modules_test.go`
+- `internal/briefing/derived_modules_test.go`
+
+Implementation:
+
+- Add `nearTermModules()` in `internal/report/near_term_report.go`.
+- Use explicit module items in this order:
+  - `module.Metadata`
+  - `module.CurrentConditions`
+  - `module.HourlyForecast`
+  - `module.PrecipTiming`
+  - `module.AlertDigest`
+  - `module.SPCConvectiveOutlooks`
+  - `module.AreaForecastDiscussion` with options:
+
+    ```go
+    module.AreaForecastDiscussionOptions{
+        Sections: []string{"key_messages", "short_term"},
+    }
+    ```
+
+  - `module.SPCConvectiveDiscussion`
+  - `module.WeatherStory`
+- Expand module `SupportedReports` in `internal/briefing/modules.go`:
+  - include `report.NearTerm` in `allReports`;
+  - include `report.NearTerm` for `HourlyForecast`;
+  - do not include `report.NearTerm` for `NarrativeForecast`;
+  - do not include `report.NearTerm` in `daypartReports`;
+  - do not include `report.NearTerm` for `DerivedDailySummary`,
+    `DerivedDaypartSummaries`, `OutdoorWindows`, or `TomorrowPlanning`.
+- Keep `PrecipTiming`, `AlertDigest`, `SPCConvectiveOutlooks`,
+  `AreaForecastDiscussion`, `SPCConvectiveDiscussion`, and `WeatherStory`
+  compatible through `allReports`.
+- Do not add a new module ID in this stage.
+
+Tests:
+
+- Add or update module registry tests proving:
+  - default near-term composition validates;
+  - all default near-term modules have builders;
+  - daily/daypart-only modules reject `report.NearTerm`;
+  - `HourlyForecast` builds for `report.NearTerm`;
+  - AFD options for the near-term default include only key messages and short
+    term.
+- Add a focused AFD module test that near-term options omit long term when the
+  source provides it.
+
+Validation:
+
+```bash
+go test ./internal/report ./internal/briefing ./internal/module
+```
+
+This stage is small enough for one implementation prompt.
+
+## Stage 3: Derived Facts For Rolling Windows
+
+Goal: teach `internal/facts` to build the facts needed by the near-term module
+set without requiring daily summaries or daypart summaries.
+
+Files to inspect:
+
+- `internal/facts/facts.go`
+- `internal/facts/facts_test.go`
+- `internal/forecast`
+- `internal/timeutil`
+- `internal/briefing/modules.go`
+
+Implementation:
+
+- Add `report.NearTerm` handling in `facts.BuildDerived`.
+- For near-term:
+  - populate `ValidPeriodHourlyPeriods` from the resolved six-hour valid
+    period;
+  - populate `ValidPeriodNarrativePeriods` if the existing generic selection
+    already does so, but do not require it for default near-term modules;
+  - build `PrecipTiming` from `ValidPeriodHourlyPeriods`;
+  - select alert overlaps using the near-term valid period;
+  - select SPC outlooks and discussions using the near-term valid period;
+  - do not build or require `DailySummaries`;
+  - do not build or require `DaypartSummaries`;
+  - do not build `StormWindowSummary`.
+- Preserve existing daily, tomorrow, three-day, weekend, and storm derivation.
+- If any existing helper assumes civil-day coverage, keep near-term on the
+  generic valid-period hourly path instead of reusing that helper.
+
+Tests:
+
+- Add facts tests for:
+  - valid-period hourly selection over a rolling six-hour window;
+  - precipitation timing based only on the near-term hourly slice;
+  - alert overlap inclusion/exclusion by near-term period;
+  - SPC outlook inclusion/exclusion by near-term period;
+  - SPC discussion records retained only for retained overlapping SPC days;
+  - no daily/daypart facts required.
+- Add a regression test that an unsupported future report still returns an
+  actionable derivation error.
+
+Validation:
+
+```bash
+go test ./internal/facts ./internal/forecast ./internal/timeutil
+```
+
+This stage is small enough for one implementation prompt.
+
+## Stage 4: App Report Mapping And CLI Command
+
+Goal: add explicit `generate near-term` support while preserving existing CLI
+syntax and app behavior.
+
+Files to inspect:
+
+- `internal/app/app.go`
+- `internal/app/app_test.go`
+- `internal/cli/root.go`
+- `internal/cli/root_test.go`
+- `cmd/weatherreporter/main.go`
+
+Implementation:
+
+- Add app report kind:
+
+  ```go
+  ReportNearTerm ReportKind = "near-term"
+  ```
+
+- Map `ReportNearTerm` to `report.NearTerm` in `reportIDForCommand`.
+- Add `near-term` to CLI generate report parsing.
+- Add help usage line:
+
+  ```text
+  weatherreporter generate near-term [--config PATH] [--units VALUE] [--tz NAME] [--out PATH]
+  ```
+
+- Reuse existing generate command flags:
+  - allow `--config`;
+  - allow `--units`;
+  - allow `--tz`;
+  - allow `--out`;
+  - do not allow or require `--date`;
+  - do not allow or require storm `--start` / `--end`.
+- Ensure the CLI returns an actionable error for unknown report names as today.
+- Do not change batch commands.
+
+Tests:
+
+- Add CLI parser tests for:
+  - `generate near-term`;
+  - `generate near-term --config PATH`;
+  - `generate near-term --units us --tz America/Chicago --out PATH`;
+  - rejected `generate near-term --date YYYY-MM-DD`;
+  - rejected storm-only `--start` / `--end` on near-term if current parser
+    behavior supports this distinction.
+- Add app resolution tests proving `ReportNearTerm` resolves `report.NearTerm`.
+- Update help tests to assert `generate near-term` appears.
+- Existing generate and run command tests must remain unchanged.
+
+Validation:
+
+```bash
+go test ./internal/app ./internal/cli
+go run ./cmd/weatherreporter --help
+```
+
+This stage is small enough for one implementation prompt.
+
+## Stage 5: End-To-End Generation And Artifact Behavior
+
+Goal: prove a near-term report can run through the app workflow and persist the
+expected artifacts.
+
+Files to inspect:
+
+- `internal/app/app_test.go`
+- `internal/state`
+- `internal/promptinput`
+- Weather API fixture server helpers in app tests
+- distributor notification tests if report paths are asserted
+
+Implementation:
+
+- Add an app-level test that generates `ReportNearTerm` with fixture weather
+  data and fake Scriptorium.
+- Assert:
+  - `ReportResult.Metadata.ReportID == report.NearTerm`;
+  - prompt ID is `weather.near_term_report`;
+  - managed report path uses artifact group `near-term`;
+  - data package path uses artifact group `near-term`;
+  - module snapshot contains the near-term module list in order;
+  - data package categories are unchanged;
+  - `hourly_forecast` contains only periods overlapping the six-hour window;
+  - `precip_timing` reflects only the six-hour window;
+  - `alert_digest` and SPC stanzas respect overlap behavior;
+  - AFD includes key messages and short term but not long term;
+  - `recent_changes.items` is empty when no rolling-window comparison exists.
+- Add an app-level case for distributor notification only if existing tests
+  assert report-specific path rendering. The expected distributor templates
+  should work through existing `{artifact_group}`, `{report_id}`,
+  `{valid_start_date}`, and `{valid_start_time}` values without special
+  near-term behavior.
+- Do not add `near_term` to scheduled batch tests.
+
+Tests:
+
+- Add stale-key checks if generated YAML is inspected:
+  - module intervals use `period_begins` / `period_ends`;
+  - top-level metadata keeps canonical `valid_period`.
+- Ensure optional output copy via `--out` continues to use existing app copy
+  behavior for generated reports.
+
+Validation:
+
+```bash
+go test ./internal/app ./internal/state ./internal/promptinput
+```
+
+This stage is small enough for one implementation prompt.
+
+## Stage 6: Config Overrides And Examples
+
+Goal: allow configured module overrides for `near_term` while keeping
+maintained examples valid.
+
+Files to inspect:
+
+- `internal/config/reports.go`
+- `internal/config/config_test.go`
+- `docs/config.md` after implementation
+- `examples/config.yml`
+
+Implementation:
+
+- Add report config key aliases:
+  - `near_term`
+  - `near-term`
+- Map both aliases to `report.NearTerm`.
+- Validate near-term module overrides through the existing module registry.
+- Ensure incompatible modules fail clearly, for example
+  `derived_daily_summary` should not be compatible with `near_term`.
+- Update config tests for:
+  - successful `reports.near_term.deterministic_modules`;
+  - successful `reports.near-term.deterministic_modules`;
+  - duplicate canonical near-term aliases rejected if both are present;
+  - incompatible daily-only module rejected.
+- Update `examples/config.yml` only if it enumerates all report module
+  overrides. If it does not need a near-term override, do not add one just to
+  demonstrate the feature.
+
+Validation:
+
+```bash
+go test ./internal/config ./internal/report ./internal/briefing
+```
+
+This stage is small enough for one implementation prompt.
+
+## Stage 7: Implemented Documentation
+
+Goal: update non-roadmap documentation after the feature exists.
+
+Files to inspect and update:
+
+- `docs/cli.md`
+- `docs/config.md`
+- `docs/operations.md`
+- `docs/internal/report-registry.md`
+- `docs/internal/module.md`
+- `docs/internal/facts.md`
+- `docs/internal/briefing.md`
+- `docs/internal/prompt-input.md`
+- `examples/config.yml`, only if changed in Stage 6
+
+Documentation requirements:
+
+- Describe `generate near-term` in CLI docs after implementation.
+- Document that the first version is explicit generation only and is not part
+  of scheduled batches.
+- Document the six-hour rolling valid period and that the duration is an
+  internal constant, not a config field.
+- Document near-term report identity, artifact group, batch output name, prompt
+  ID, and module composition in internal docs.
+- Document near-term config override keys only if Stage 6 implements them.
+- Keep deferred items under roadmap docs only:
+  - configurable duration;
+  - batch membership;
+  - dedicated `derived_near_term_summary`;
+  - near-term Recent Changes comparison output.
+
+Acceptance criteria:
+
+- Non-roadmap docs describe only implemented behavior.
+- Docs do not imply a duration config field or scheduled batch behavior.
+- Maintained examples load.
+
+Validation:
+
+```bash
+go test ./internal/config
+git diff --check
+```
+
+This stage is small enough for one implementation prompt.
+
+## Stage 8: Final Validation
+
+Goal: run the complete project validation after implementation and docs are
+updated.
+
+Commands:
+
+```bash
+go test ./...
+go run ./cmd/weatherreporter --help
+git diff --check
+```
+
+Manual checks:
+
+- `weatherreporter --help` lists `generate near-term`.
+- No existing command syntax changed.
+- `near_term` is absent from morning and evening batch membership.
+- No non-roadmap docs describe unimplemented deferred near-term work.
+- No config examples include secrets or invalid module IDs.
+- Distributor bundle path rendering remains template-driven and does not need
+  report-specific branching.
+
+This stage is small enough for one implementation prompt.
+
+## Deferred Work
+
+Do not include these in the first implementation:
+
+- user-configurable near-term duration;
+- scheduled near-term batch membership or a new high-frequency batch command;
+- dedicated `derived_near_term_summary`;
+- narrative forecast periods in the default near-term module list;
+- separate AFD section modules;
+- rolling-window Recent Changes comparison output;
+- custom CLI duration flags;
+- distributor-specific behavior for near-term reports.
+
+## Open Questions
+
+None block implementation.
+
+Recommendation: keep the first version explicit and narrow: `generate
+near-term`, six-hour constant, no batch membership, no Recent Changes output.
+This fits the existing registry/module architecture and lets prompt quality be
+tested before adding scheduler or comparison complexity.
+
+Viable alternative: implement rolling-window Recent Changes immediately by
+finding the most recent prior `near_term` report with an overlapping or adjacent
+window. That could be useful later, but it needs a well-defined comparison
+contract and should not block the first report implementation.

+# Near-Term Report Roadmap
+
+## Purpose
+
+This roadmap defines planned work to add a rolling `near_term` report focused
+on the next several hours. The feature is not implemented yet, so this document
+lives under `docs/roadmap/`.
+
+The goal is a frequently generated report that helps readers understand what
+matters in the immediate future: current conditions, hourly evolution,
+precipitation timing, applicable hazards, applicable SPC risk products, and the
+most relevant short-term narrative context.
+
+## Target Behavior
+
+Add a generated report with:
+
+- report ID: `near_term`
+- display name: `Near-Term Report`
+- prompt ID: `weather.near_term_report`
+- artifact group: `near-term`
+- batch output name: `near-term.md`
+- default valid-period length: 6 hours
+- valid period: `[generation_time, generation_time + nearTermHours)`
+
+The report should use a package-owned constant for the valid-period length, for
+example:
+
+```go
+const nearTermHours = 6
+```
+
+Do not make the duration configurable in the first implementation. The constant
+exists so the value can be changed later to 4 or 8 hours without changing
+valid-period logic in multiple places.
+
+## Locked Decisions
+
+- The report ID is `near_term`.
+- The report is rolling and generation-time anchored, not civil-day anchored.
+- The first implementation covers the next 6 hours through a constant.
+- The report should be generated explicitly by CLI command before deciding
+  whether it belongs in scheduled batches.
+- The first implementation should declare `rolling_window` comparison policy
+  but should not emit Recent Changes output for `near_term`.
+- Alert and SPC products should be included only when their valid periods
+  overlap the resolved near-term report period.
+- SPC discussion text should keep the existing categorical-risk threshold rule
+  and should still require overlap with the near-term report period.
+- The AFD stanza should include key messages and short term text by default.
+- Daily-only modules should not be forced into this report.
+
+## Report Definition
+
+Add a report definition under `internal/report`, preferably in a focused
+`near_term_report.go` file.
+
+Definition fields:
+
+- `ID`: `NearTerm`
+- `Name`: `Near-Term Report`
+- `PromptID`: `weather.near_term_report`
+- `ComparisonStrategy`: `rolling_window`
+- `ArtifactGroup`: `near-term`
+- `BatchOutputName`: `near-term.md`
+- `Generated`: `true`
+- `CompatiblePriorIDs`: `[]ID{NearTerm}`
+- `Modules`: near-term module list below
+- `resolve`: rolling near-term resolver
+
+Valid-period resolver:
+
+```go
+func resolveNearTerm(req ResolveRequest) (timeutil.Period, error) {
+    localNow := req.Now.In(req.Location)
+    return timeutil.Period{
+        Start: localNow,
+        End:   localNow.Add(nearTermHours * time.Hour),
+    }, nil
+}
+```
+
+The implementation should use idiomatic package-local constants and avoid
+duplicating duration literals in tests or app code.
+
+## Default Module Composition
+
+Default module order should be:
+
+1. `metadata`
+2. `current_conditions`
+3. `hourly_forecast`
+4. `precip_timing`
+5. `alert_digest`
+6. `spc_convective_outlooks`
+7. `area_forecast_discussion`
+8. `spc_convective_discussion`
+9. `weather_story`
+
+`area_forecast_discussion` should use options equivalent to:
+
+```yaml
+sections:
+  - key_messages
+  - short_term
+```
+
+Do not include these daily/daypart-oriented modules initially:
+
+- `derived_daily_summary`
+- `derived_daypart_summaries`
+- `outdoor_windows`
+- `tomorrow_planning`
+
+If the report needs deterministic summary facts later, add a purpose-built
+module such as `derived_near_term_summary` rather than stretching daily modules
+into a rolling sub-daily context.
+
+## Prompt Package Shape
+
+The existing prompt-input category layout should remain unchanged:
+
+- `applicable_risk_products`
+- `derived_summaries`
+- `narrative_products`
+- `raw_data`
+
+Near-term output is expected to emphasize:
+
+- `current_conditions` and `hourly_forecast` under `raw_data`
+- `precip_timing` under `derived_summaries`
+- `alert_digest` and `spc_convective_outlooks` under
+  `applicable_risk_products`
+- `area_forecast_discussion`, `spc_convective_discussion`, and
+  `weather_story` under `narrative_products`
+
+Module interval fields should use the existing prompt-facing
+`period_begins` / `period_ends` convention.
+
+## Overlap And Filtering Rules
+
+Hourly forecast:
+
+- use only hourly periods overlapping the near-term valid period;
+- preserve hourly period order;
+- do not include the full daily forecast.
+
+Narrative products:
+
+- AFD key messages and short term text may be included because the AFD is an
+  official short-term forecast discussion product;
+- narrative forecast periods are not included by default unless a later prompt
+  test shows they improve near-term output.
+
+Alerts:
+
+- include active alert overlaps only when the alert overlaps the near-term
+  valid period;
+- if alerts were checked successfully and no alerts overlap, emit checked empty
+  alert context through existing module behavior.
+
+SPC outlooks:
+
+- include only retained outlooks whose valid periods overlap the near-term
+  valid period;
+- do not include non-overlapping outlooks even if they are severe;
+- keep current prompt-facing field exclusions for geometry, severity rank,
+  expiration time, and source URL.
+
+SPC discussion:
+
+- include discussion only for SPC days where a retained overlapping categorical
+  outlook has severity rank at least `3`;
+- do not include discussion for low-risk, non-categorical-only, or
+  non-overlapping outlooks.
+
+Weather story:
+
+- include when available under current optional-source behavior;
+- do not require the story valid period to exactly match the near-term period
+  unless later testing shows stale stories are a problem.
+
+## Implementation Stages
+
+### Stage 1: Report Registry
+
+Goal: add the `near_term` report definition and valid-period resolver.
+
+Files to inspect or update:
+
+- `internal/report/definition.go`
+- `internal/report/registry.go`
+- `internal/report/period.go`
+- new `internal/report/near_term_report.go`
+- `internal/report/period_test.go`
+- `docs/internal/report-registry.md` after implementation
+
+Acceptance criteria:
+
+- `report.DefaultRegistry().Lookup(report.NearTerm)` succeeds.
+- `report.Registry.All()` includes the report in a stable order.
+- resolving the report at a fixed generation time produces a half-open
+  six-hour period.
+- report metadata and RunID include `near_term`.
+
+### Stage 2: Module Compatibility And Defaults
+
+Goal: allow existing relevant modules to build for `near_term` and define the
+default near-term composition.
+
+Files to inspect or update:
+
+- `internal/briefing/modules.go`
+- `internal/report/near_term_report.go`
+- `internal/briefing/*_module_test.go`
+- `internal/module/module_test.go`
+
+Acceptance criteria:
+
+- all default near-term modules validate and build from appropriate test facts;
+- daily-only modules remain incompatible unless intentionally expanded;
+- `area_forecast_discussion` defaults to key messages and short term only for
+  this report.
+
+### Stage 3: Derived Facts
+
+Goal: make `internal/facts` derive report-period facts for `near_term`.
+
+Files to inspect or update:
+
+- `internal/facts/facts.go`
+- `internal/facts/facts_test.go`
+- `internal/forecast` selection helpers, if needed
+
+Acceptance criteria:
+
+- valid-period hourly periods are sliced to the six-hour window;
+- precipitation timing is built from that six-hour hourly slice;
+- alert overlaps use the near-term valid period;
+- SPC outlook and discussion derivation use the near-term valid period;
+- no daily summaries or daypart summaries are required for the default
+  near-term module set.
+
+### Stage 4: CLI And App Wiring
+
+Goal: add explicit generation support without changing existing commands.
+
+Files to inspect or update:
+
+- `internal/app`
+- `internal/cli`
+- `cmd/weatherreporter/main.go`
+- `docs/cli.md` after implementation
+
+Expected command:
+
+```bash
+weatherreporter generate near-term [--config PATH] [--units VALUE] [--tz NAME] [--out PATH]
+```
+
+Acceptance criteria:
+
+- command maps to `report.NearTerm`;
+- no `--date`, `--start`, or `--end` flags are added for this report;
+- existing `generate daily`, `generate tomorrow`, `generate three-day`,
+  `generate weekend`, and `generate storm` behavior is unchanged;
+- CLI help lists the new command.
+
+### Stage 5: Prompt Input And State Coverage
+
+Goal: prove the managed module snapshot and data package contain the intended
+near-term stanzas.
+
+Files to inspect or update:
+
+- `internal/app/app_test.go`
+- `internal/promptinput`
+- `internal/state`
+
+Acceptance criteria:
+
+- generated module snapshot includes the near-term default module list in
+  order;
+- data package uses existing categories;
+- alert/SPC stanzas are omitted or checked-empty according to current module
+  behavior and valid-period overlap;
+- report metadata preserves canonical `valid_period`;
+- module interval labels use `period_begins` and `period_ends`.
+
+### Stage 6: Documentation And Examples
+
+Goal: document implemented behavior only after the code exists.
+
+Files to inspect or update after implementation:
+
+- `docs/cli.md`
+- `docs/internal/report-registry.md`
+- `docs/internal/module.md`
+- `docs/internal/facts.md`
+- `docs/internal/briefing.md`
+- `docs/config.md` only if report module overrides need an example update
+- `examples/config.yml` only if it lists report module overrides
+
+Acceptance criteria:
+
+- non-roadmap docs describe `near_term` only after implementation;
+- future or deferred near-term summary modules remain under roadmap docs;
+- examples, if updated, load through existing config tests.
+
+## Test Plan
+
+Focused tests:
+
+```bash
+go test ./internal/report ./internal/briefing ./internal/facts
+go test ./internal/app ./internal/cli ./internal/promptinput
+```
+
+Full validation:
+
+```bash
+go test ./...
+go run ./cmd/weatherreporter --help
+git diff --check
+```
+
+Important coverage:
+
+- six-hour valid-period resolution from a fixed generation time;
+- timezone-aware period start and end;
+- no civil-day truncation;
+- hourly periods selected by overlap with the rolling window;
+- alert overlap filtering;
+- SPC outlook filtering by overlap;
+- SPC discussion filtering by overlap plus categorical severity threshold;
+- AFD key messages and short term included;
+- daily-only modules rejected or absent from default near-term composition;
+- distributor bundle path templates render sensibly for a sub-daily report,
+  especially valid start time variables.
+
+## Deferred Work
+
+Do not include these in the first implementation:
+
+- user-configurable near-term duration;
+- adding `near_term` to scheduled morning or evening batches;
+- a dedicated `derived_near_term_summary` module;
+- narrative forecast periods by default;
+- separate AFD section modules;
+- near-term-specific Recent Changes comparison output;
+- CLI flags for custom near-term duration.
+
+## Open Questions
+
+None block the roadmap.
+
+Recommendation: implement the first version as explicit `generate near-term`
+only, with no scheduled batch membership. That keeps the user-visible behavior
+small while the prompt and generated report are tested.
+
+Viable alternative: add `near_term` to a frequent scheduled batch immediately.
+That may be useful operationally, but it should wait until the report cadence
+and downstream distributor behavior are clear.
