PLAN — Bike-Tinder

Status: Build phase — Phase 1 complete (2026-11-10); Phase 2 not yet started. Phases are gated: each lands, is verified, then the next begins. Glenn's standing rule applies — "pause" stops all spend immediately.

v1 goal

A single-source, single-user, tailnet-only Tinder-style PWA on the Rotarran: nightly-updated catalog, swipe deck (Like / Nope / Maybe), full editable list, taste-ranked ordering.

Phase 0 — Planning

• Engineering consultation (Torres) → memo
• Design docs in this repo: SOURCES, DESIGN, DATA-MODEL, RANKING, UI-SPEC
• Glenn's calls (2026-11-10): v1 source = Kijiji · deck = show all, taste-ranked · new-bike feed = in-app badge only
• Repo housekeeping (2026-11-10): branches dev/main/release · dedicated bike-tinder-import cron (parked for deploy) · stack-owned Tailscale sidecar in the deploy plan
• Build gate opened — Glenn green-lit (2026-11-10)
• Exit criteria: docs merged to main (done 2026-11-10); source decision recorded in SOURCES.md.

Phase 1 — Data spine

Status: complete (2026-11-10). Built by Torres on dev (5bf180c..19e46cd), independently re-verified by Alex (fresh-DB import x2, deck CLI, 8/8 selfcheck), merged to main (d890dcd). Live result: 640 rows → 560 active + 80 dup; deck top = Indian Scout family (91) then Vulcan 900 Classic (73).

(Build work lands on dev; verified milestones merge to main; deploys track release.)

• DB schema + migrations (SQLite)
• Importer: source catalog → upsert into DB (new / changed / gone states)
• Cold-start scoring wired (existing rubric logic)
• Proof: CLI query shows a ranked, deduped queue from the real live catalog
• Exit criteria: importer runs clean twice in a row (done — idempotent); counts reconcile against the source (done — 560+0+80=640); no schema surprises (done).

Carried into Phase 2 from P1 findings:

• Dedupe pairing refinement — multi-unit dealer groups (BMW G 310 R, 2 groups) over-merge under the v1 collapse-to-one rule; min(ns,nb) pairing → 77 dup, keeps sibling rows visible. Revisit before launch.
• Image backfill is priority — only ~20/640 rows carry an image in the state; the DESIGN bootstrap backfill is essential for the deck.
• Dealer-blast mitigation + Stage 1.5 swipe boost matter immediately — only ~67/560 active rows are family-scored; the rest sort below.

Phase 2 — The swipe app (core)

Status: in build (Torres, 2026-11-10) on dev. Contract frozen: UI-SPEC.md v2 + reference/mockup-001-fidelity.html (Variant A "Pure", approved by Glenn; 5-deep live stack, no-lock commit, dossier sheet). Image backfill underway at freeze (hunt motorcycle-hunt-img.py, 620 listings) + app-side mirror (app/imgfetch.py).

• 2–3 UI mock variants → Glenn picked Variant A "Pure" (approved 2026-11-10 after two fix rounds)
• API (deck cursor, swipe upsert/clear, list + filters, stats, media, import) + PWA frontend (faithful mockup port: stack engine, drag, Like / Nope / Maybe, dossier, empty/undo) — no match overlay (removed by Glenn's call)
• Full list view with inline edit; basic filters (decision + sort + search)
• Proof: runs locally on :9453; exercised on Glenn's phone over the tailnet
• Exit criteria: Glenn can swipe a real deck on his phone and edit results in the list.

Phase 3 — Personalization

• Swipe history → nightly retrain of explainable ranking
• Trends panel ("you lean: …"); "because you liked X" chips
• Deck ordering by learned taste with cold-start guardrails
• Exit criteria: after ~30 swipes, deck order visibly reflects taste; explainability shown in UI.

Phase 4 — Deploy + automate

• Podman compose stack at /var/mnt/DATA/podman-stacks/bike-tinder/ + systemd unit (Delegate=yes) + in-stack Tailscale sidecar serving https://biketinder.tailf35a34.ts.net; PWA install on Glenn's phone
• Enable the new bike-tinder-import Hermes cron (08:30 daily, post-hunt; script-only, zero LLM; parked until deploy); DB backup routine
• Runbook in DESIGN.md; announce + handover note
• Exit criteria: survives a reboot; refreshes overnight unattended; installable and used from the phone.

Non-goals (v1)

• Multi-user accounts, social features, comments
• Additional sources (v2+); Facebook (never — manual by Glenn)
• Notifications beyond what already exists (Conduit is the house channel)
• Buying workflow (contact/inspection tracking) — possible v2

Open decisions

• v1 source — resolved 2026-11-10: Kijiji (see docs/SOURCES.md)
• Mockup direction — Glenn picks at Phase 2 start
