Implements the fit-parsing-hardening change. The shared converter now:
- splits output into <trkseg>s on timer stop/start events, falling back to
record gaps > 5 min, so downstream moving-time never bridges a pause;
- slices records into per-session windows (multisport → one activity, one
segment per session), single-session behavior unchanged;
- validates records: finite/in-range coordinates required, timestamp
required, non-finite altitude dropped (point kept), prefers
enhanced_altitude;
- returns { gpx, sport }, mapping FIT session sport/sub-sport to a Journal
SportType (first session wins), consumed by the Wahoo importer + webhook
and Garmin importer as a fallback when the provider sends no type.
Tests drive the converter via mocked fit-file-parser output (segmentation,
validation, sport mapping, no-GPS) per the chosen fixtures approach.

Garmin Connect as the third connected-services provider (spec:
garmin-import). The interesting parts:
- Push-first ingestion: Garmin has no list endpoint. The webhook
normalizes ping (callbackURL) and push (inline) notification batches
into events; the slow work (authorized FIT download, FIT→GPX via the
shared converter, activity creation) runs in a garmin-import-activity
pg-boss job so the webhook answers fast. Callback URLs are validated
against Garmin's API host before any fetch (SSRF guard).
- History via backfill requests: /sync/import/garmin is a date-range
requester with honest async progress (no pick list — the concept
doesn't exist in a push model). Ranges chunk to Garmin's 90-day cap;
overlaps are free via sync_imports dedupe. Requests persist in
import_batches via two new nullable columns (range_start/range_end).
- OAuth2 + PKCE on the existing oauth credential kind. Design
correction from apply: the verifier rides a short-lived httpOnly
cookie scoped to the callback path — the state param is visible in
redirect URLs and must never carry it. Manifests opt in via pkce:true.
- Deregistration notifications flip the connection to 'revoked'
(row kept for audit, imports retained, re-connect prompt shown).
- Framework evolutions, all additive: parseWebhook returns
WebhookEvent[] (Garmin batches; Wahoo adapted), manifest gains
configured()/importUrl/pkce, importActivity accepts summary stats
for FIT-less imports, manager gains markRevoked.
- Env-gated: no GARMIN_CLIENT_ID → provider hidden on
/settings/connections. Privacy manifest entry (DE+EN). i18n en+de.
Rollout (§6) stays gated on the Garmin Developer Program application
(submitted 2026-06-07). Fixtures are doc-shaped; the staging soak
swaps in recorded payloads if shapes differ.
Gate: typecheck ✓ lint ✓ unit+integration ✓ e2e 70/72 + both known
flakes green isolated ✓ openspec validate ✓
