The route-surface-breakdown change is fully implemented (18/18 tasks,
all artifacts done). Archive it via `openspec archive` (CLI 1.6.0):
- Moves the change to openspec/changes/archive/2026-07-13-route-surface-breakdown/
- Promotes its 5 delta requirements into a new capability spec at
openspec/specs/route-surface-breakdown/spec.md (surface/waytype
breakdown from BRouter waytags, async Overpass backfill, live SSE
update, proportion bars, localized labels)
Purpose paragraph filled in (the CLI leaves a TBD placeholder). Both the
spec and archived change pass `openspec validate --strict`.

Builds on the merged A-only proposal. Broadens the capability:
- breakdown now on routes AND activities;
- Path 1 (sync) unchanged: BRouter waytags → breakdown at Planner save;
- Path 2 (async): a `surface-backfill` pg-boss job map-matches geometry to OSM
via Overpass for imports/uploads/older rows, stores the breakdown, and pushes
a `surface_breakdown` SSE event so an open detail page fills in live;
- privacy note: backfill sends geometry to Overpass → route via the proxy /
self-hostable Overpass; documented in the manifest.
Validates with `openspec validate --strict`. Specs only; no code.

Surface + waytype proportion bars on route detail, from the BRouter waytags the
Planner already computes (and currently discards on save). Design records the
data-source decision: persist a compact distance-weighted breakdown for
Planner-created routes (accurate, no external call); Overpass map-matching for
imports/uploads is parked as a future option.
