Deletes features the owner decided to kill based on prod usage, plus helpers with no callers outside tests. 47 files, +41 / −3810.

Popups except achievements: upload_meme, telegram_channel, github_repo, feedback (+ popups.yml, channel-subscribe check and events)	owner decision; note: this removes the live, rarely firing channel-subscribe popup at meme #5 (~3 sends/30d)	~−380

Dead helpers: 4 in stats/service.py, RedisData/set_redis_key/get_by_key, charge_user, get_latest_chat_messages, UserTg, check_openrouter_key_health, get_source_candidate_vote_counts, TREASURY_USER_ID	grep: callers only in tests (tests now go through get_usable_openrouter_keys / a direct vote select)	~−200
Crosspost n_sub_likes shadow enrichment	not part of v5/v5c/v5f; only its own unit test and an old readout doc used it	−90
Table defs with 0 references: meme_raw_ig (+2 SQL joins), user_channel_membership, channel_lifecycle_event, editorial_posts/_snapshots (+ editorial branch in stats_collector.py, crosspost path untouched), inline_search_*, user_wrapped, chat_agent_usage, friend_challenge_*	grep	−212
Deps: openai (0 imports), pydantic[email] → pydantic (no EmailStr), OPENAI_API_KEY	grep	−4

Kept on purpose:

• All DB tables. No drop migration. Note: alembic revision --autogenerate will now propose dropping the tables whose Table defs were removed, so strip those ops from future autogenerated migrations.
• All TrxType members and PAYOUTS entries, for historical treasury_trx rows.
• The friend_challenge exclusion in meme stats SQL. It does nothing now but is harmless.
• specs/burger-tokenomics.md updated to match.

Tests (local): tests/tgbot tests/crossposting tests/stats tests/storage tests/test_crossposting_meme.py 315 passed; tests/flows tests/test_redaction_audit.py 35 passed. tests/admin fails to collect locally because of an unrelated FastAPI version mismatch in my local env. ruff check and ruff format are clean.
