# v3 tickets

One file per feature, in the shape that worked for v2: Goal · Context · Design ·
Implementation · Acceptance criteria · Tests · Risks · Out of scope. Written before
implementing, so the risks are on paper before they are walked into.

Menu, not a commitment. Nothing here is scheduled.

**Everything in v3 is buildable with no server.** Group rides, accounts and paid cloud
backup are v4 — see [../BACKLOG.md](../BACKLOG.md).

> **Before starting anything:** [../port/REAL-RIDE-CHECKLIST.md](../port/REAL-RIDE-CHECKLIST.md).
> The port has never recorded a real ride, and item I3 may still force a change of GPS
> engine — which would land underneath several of these tickets.

**V3-08/V3-09 are deferred, on request**, pending V3-17 (self-hosted OSRM). See V3-17's
own note on why that also puts them in tension with this document's v3/v4 boundary —
unresolved by design, not an oversight.

## Three that carry more weight than their size suggests

**V3-01** ships the port's **first real migration**. The destructive fallback is gone, so
getting `addColumn` plus a v1-database test right matters more than the feature does —
V3-07 and V3-09 both add migrations behind it.

**V3-08** forces a routing-engine decision with ongoing cost and vendor implications.
Behind a `RoutingService` interface, mirroring what `LocationSource` did for GPS. The
direction is decided (self-hosted OSRM); V3-17 does the actual standing-up, and V3-08 is
deferred until it exists.

**V3-13** is not code. It answers the three questions that have been open since v2, and
**V3-15 may close unbuilt** as a result — a legitimate and probably likely outcome.

## Suggested order, if starting cold

1. **V3-01** — proves the migration path while the stakes are low, and unblocks V3-08/14
2. **V3-02 + V3-03** — small, self-contained, gives V3-01 a home
3. **V3-04** — the most visible change, and the gateway to four other tickets
4. **V3-07** — entirely independent; useful on its own before the routing decision
5. **V3-13** — as soon as there is a ride to measure

V3-12 is a good filler at any point. V3-16 should wait until the screens stop moving.
