+Daily uses template ID `daily`, generated-text schema ID `daily`, and prompt
+source `internal/reporttemplate/prompts/daily.generated_text.md`.
+
+Daily modules include the Hourly module fields plus:
+
+| Variable | Type | Description |
+| --- | --- | --- |
+| `.Modules.DerivedDailySummary` | *briefing.DerivedDailySummaryModule | Daily summary facts for the forecast date. |
+| `.Modules.DerivedDaypartSummaries` | *map[string]briefing.DerivedDaypartSummaryModule | Raw daypart summary map, when direct keyed access is needed. |
+| `.Modules.Dayparts` | []generatedtext.DailyDaypartContext | Ordered daypart summaries for deterministic template rendering. |
+| `.Modules.DailyPlanning` | *briefing.DailyPlanningModule | Planning facts for the selected local civil day. |
+
+Prefer `.Modules.Dayparts` over ranging through
+`.Modules.DerivedDaypartSummaries`; it follows configured daypart order and
+falls back to sorted keys for any unmatched entries.

+TASK: You are writing structured prose slots for a dated daily weather report.
+
+The calling application will render the final Markdown report. Your job is not to write the full report. Return only a JSON object matching the configured schema.
+
+Use only the supplied `data_package`. Do not invent weather details, times, hazards, probabilities, or impacts that are not supported by the data.
+
+The report focuses on the selected local civil day in `report.valid_period` for the configured location.
+
+Return these fields:
+
+- `summary`: required. 1-2 sentences summarizing the main weather story for the selected day.
+- `forecast_discussion`: required. 1 or more short paragraphs explaining the setup, timing, trend, or uncertainty most relevant to the selected day.
+- `precipitation_timing`: optional. Include only when the deterministic `precip_timing` module contains precipitation windows.
+- `confidence`: optional. Include only if uncertainty, timing spread, or conflicting signals materially affect how the reader should interpret the forecast.
+
+Return JSON only.
+
+# summary
+
+Lead with the most practical local outcome for the selected day. If an active warning is relevant during the report period, lead with the hazard.
+
+Mention the expected temperature character, precipitation risk, wind, visibility, heat, cold, or other hazards only when supported by the data package.
+
+# forecast_discussion
+
+Use deterministic module facts and narrative products to explain the most useful details for the selected day.
+
+Useful context may include:
+
+- timing of condition changes by daypart or hour
+- boundaries, forcing, moisture, instability, or storm mode when supported
+- active alerts or SPC outlooks that apply to the location
+- planning concerns surfaced by `daily_planning`
+- confidence or uncertainty
+
+# precipitation_timing
+
+Use 1-2 sentences to add practical precipitation context only when the data package contains deterministic precipitation windows. Include expected timing, type, intensity, duration, and uncertainty only when those details are supported.
