+# Entry Enrichment — Design Spec
+
+**Date:** 2026-06-21
+**Status:** Approved
+
+## Overview
+
+Enrich all real trip journal entries with `location_city`, `location_country`, `lat`, `lng`, `weather_temp_c`, and `weather_desc` using an in-chat review workflow. One Markdown review doc per trip; Claude infers values, user corrects, Claude applies to YAML.
+
+---
+
+## Scope
+
+### What this covers
+
+- Filling in `location_city` and `location_country` where blank
+- Geocoding to `lat`/`lng` for all entries with a city
+- Approximate seasonal `weather_temp_c` and `weather_desc` for each entry date + location
+- Three real trips: `central-asia-2023`, `us-canada-mex-2024`, `italy-2025`
+
+### What this does not cover
+
+- Adding new journal entries (content creation)
+- Adding GPX tracks to central-asia or us-canada-mex
+- Historical weather API lookups (values are seasonal approximations, not exact)
+
+---
+
+## Review Document Format
+
+One file per trip at `docs/enrichment/{trip-slug}.md`.
+
+### Table columns
+
+| Column | Source | Notes |
+|---|---|---|
+| Entry | folder name | e.g. `2023-09-05-pixelfed-8.entry` |
+| Date | `date` frontmatter | `YYYY-MM-DD` |
+| Title | `title` frontmatter | Read-only reference |
+| City | inferred from title+body | Edit to correct |
+| Country | inferred from title+body | Edit to correct |
+| Lat | extracted from Map Link | Do not edit directly; update Map Link instead |
+| Lng | extracted from Map Link | Do not edit directly; update Map Link instead |
+| Map Link | OSM link `https://www.openstreetmap.org/#map=15/{lat}/{lng}` | Replace with corrected OSM or Google Maps link |
+| Temp °C | seasonal approximation | Edit directly if wrong |
+| Weather | seasonal approximation | Edit directly if wrong (e.g. `sunny`, `cloudy`, `rainy`) |
+
+### Coordinate extraction rules
+
+When reading back a reviewed doc, extract lat/lng from Map Link using these URL patterns:
+
+- **OSM:** `openstreetmap.org/#map={zoom}/{lat}/{lng}` → use the two numbers after `#map=N/`
+- **Google Maps:** `maps.google.com/.../@{lat},{lng},{zoom}z` or `maps.app.goo.gl/...` (follow redirect, then parse)
+
+If a cell has no Map Link (blank city), lat/lng are left empty.
+
+---
+
+## Inference Rules
+
+1. Read `title` first — most locations are explicit ("Poutine and French Echoes in Old Montreal").
+2. Fall back to body text if title is ambiguous.
+3. If neither title nor body reveals a location, leave City/Country blank and note it for manual fill.
+4. City = the specific city or town; Country = the country.
+
+---
+
+## Weather Approximation
+
+Fill `weather_temp_c` with a single integer (the approximate daytime high in °C for that city + month). Fill `weather_desc` with one word: `sunny`, `cloudy`, `partly cloudy`, `rainy`, `cold`, or `hot`. Based on known climate patterns — not historical API data.
+
+---
+
+## Application Step
+
+After user approves a reviewed doc, Claude:
+
+1. Re-reads the table row by row
+2. Extracts coordinates from Map Link (or leaves blank if no link)
+3. Updates the corresponding `entry.md` frontmatter fields in-place
+4. Reports a summary of changes made
+
+No scripts are written — changes are applied directly via Edit tool.
+
+---
+
+## Order of Execution
+
+1. `central-asia-2023` — 22 entries (generate doc → review → apply)
+2. `us-canada-mex-2024` — 12 entries (generate doc → review → apply)
+3. `italy-2025` — 2 entries (generate doc → review → apply)
