EM: remove 260 lines of shelved matching code from intake/router.py

[brooksRoley]

What

Removes all shelved psychometric-matching code from server/app/intake/router.py. Matching was shelved per CLAUDE.md Creative Direction; this dead code was flagged twice in the Running Notes ledger (flag_count: 2, owner: agent).

Deleted: GET /match (~180 lines)

The full user-matching pipeline: Pinecone nearest-user query, match_interactions table reads (both directions), Spotify/Twitter/Strava/Oracle overlap computation, and human-readable match-reason generation. Zero callers since matching was shelved. References find_nearest_users (Pinecone ANN), match_interactions table, and five helper functions below.

Deleted: 5 helper functions (~70 lines)

• _build_match_reason — GPT-style match explanation from psychological coordinates
• _extract_spotify_overlap — genre/artist/audio-feature comparison between two users
• _extract_twitter_overlap — tweet-length and language comparison
• _extract_strava_overlap — shared activity-type intersection
• _extract_oracle_insight — oracle coordinate extraction for match display

Deleted: POST /fitting (~15 lines)

Saved fitting_self / fitting_ideal avatar JSON to vibe_vectors. Part of the shelved fitting-ritual / swipe flow (FittingView, RevealView — also shelved).

Updated: imports

• Removed FittingRequest from .models import (model definition in models.py stays — it's harmless there)
• Removed find_nearest_users from ..vector.service import (query_relevant_journal and upsert_user_vector remain — both used by POST /confess)

Kept: GET /vector and POST /confess

GET /vector returns the current user's own vibe vector (attachment style, defense mechanism, readiness score) — legitimately used by the psychoanalysis pipeline, not matching. Kept.

Verified

• Opened server/app/intake/router.py on main (SHA: 0be6f0fd) today — confirmed GET /match queries find_nearest_users and match_interactions, both dead since matching was shelved.
• POST /fitting writes fitting_self/fitting_ideal columns — shelved fitting ritual, no frontend consumers since PR Remove shelved matching routes and views (/game, /messages) #9.
• No other file in the repo calls GET /intake/match or POST /intake/fitting (all routing was removed with the matching frontend in earlier PRs).

Net change

~260 lines deleted, 0 added. Router goes from ~370 → ~110 lines.

Livelihood stream

Code quality / portfolio signal — dead code creates cognitive overhead for contributors, misleads readers about what the product does, and inflates onboarding cost. Keeps the codebase honest about what's actually shipped.

Superseded by #69, which removes the same shelved /match matching code but preserves POST /fitting. #54 also deleted the fitting endpoint, which would break the fitting ritual (a kept feature — FittingRitualView depends on it).
