Seed the rewrite: profile, calibration, and repo scaffolding

Ground-up replacement for news_triage, whose signal quality failed because it
had no representation of what its user likes -- three keywords fed to BM25 plus
a two-term substring blocklist.

profile/ holds the taste model as prose and TOML: 11 interest blocks, 3 veto
blocks, 5 importance blocks, each a set of probe sentences to be embedded.

The [scoring] constants are fitted, not guessed. CALIBRATION.md records the
measurements against all 3,885 items in the v0.2 database and 40 real feedback
labels, including two findings that changed the design:

- compare blocks by z-score within block, never raw cosine; raw cosine let
  geopolitics win 78% of items and buried known-liked items at median rank 1246
  of 3885 (293 after normalizing)
- veto needs a margin over the interest signal, not a threshold; a plain 0.55
  cutoff falsely killed "Belgian mayor blocks club from hosting Israeli opponent
  in Europa League", which the old substring blocklist also killed

+# Connor's news profile
+
+The thing the previous system never had. `news_triage` v0.2's entire model of taste was
+three keywords and two blocked substrings; everything else was ranking machinery with
+nothing meaningful to rank. This file is the replacement, and `profile.toml` is its
+machine-readable form.
+
+Written 2026-09-08, from a structured interview plus evidence from 32 real feedback
+clicks in the v0.2 database.
+
+## How this is used
+
+Every `description` and `probe` below is embedded (bge-small-en-v1.5, CPU) into a vector.
+Item relevance is the **max** cosine similarity across probes, never the mean — averaging
+"Middle East geopolitics" with "grid-scale energy storage" produces a vector near neither.
+Feedback then moves these vectors over time (Rocchio); the written text is the cold-start
+seed so the system is useful on day one instead of after 200 clicks.
+
+Vetoes work the same way, as *regions* rather than strings. This is the whole point: the old
+system could not express "sports" as a concept, only as the literal characters `s-p-o-r-t-s`,
+which is why 18 of 32 feedback clicks were Connor hand-rejecting AP baseball recaps that a
+`blocklist = ["sports"]` never matched.
+
+## Interests
+
+Ordered roughly by strength. Weights are multipliers on the similarity score.
+
+1. **Geopolitics and conflict** (1.0) — the strongest and most consistent signal. Middle East
+   above all, plus great-power dynamics: China's expanding global reach, US foreign policy,
+   war and escalation, sanctions, the UN.
+2. **Tech and science policy** (0.9) — AI regulation, platform governance, surveillance and
+   privacy law, research funding. Policy *about* technology.
+3. **Labor, inequality and social policy** (0.9) — the "democratic socialism" of the old
+   config, read properly: unions, strikes, wages, housing, healthcare, education, welfare
+   states.
+4. **Software and systems, deep** (0.9) — Connor runs a self-hosted inference stack and a
+   substantial homelab. Rust and WASM, systems programming, self-hosting, local model
+   inference, and release notes for things he actually runs. **Eligible for push**, not
+   digest-only — this was an explicit choice.
+5. **Urbanism and city planning** (0.8) — transit, zoning, housing density, street design,
+   public space. New in this profile; entirely absent from v0.2.
+6. **Energy, climate and infrastructure** (0.6) — grid buildout, storage, renewables, climate
+   policy. Real but explicitly weaker than the others.
+7. **Global South** (0.6) — Africa, South Asia, Latin America. Not selected in the interview,
+   but three of the fourteen starred items were Uber exiting Nigeria and Uganda, India's grid
+   and storage crunch, and explosions at a Bolivian military base. Carried at a modest weight
+   on that evidence. **Flagged for review** — drop it if it turns out to be noise.
+
+### Geography
+
+- **Cincinnati** — where he lives. Local politics and city stories, at a much lower
+  importance bar than world news.
+- **Louisville / Kentucky** — where he is from. Still wanted, weaker than Cincinnati.
+- **Ohio** — state politics.
+- **US national politics** — federal policy, courts, elections, legislation.
+- **Italy** and **Mexico** — specific standing country interests.
+
+## Vetoes
+
+- **US big-three sports** — professional and college basketball, American football, baseball,
+  and hockey. Game recaps, scores, trades, drafts, salary-cap news, betting lines.
+- **Royal and celebrity gossip** — the British royal family, red carpets, box office,
+  influencer drama.
+- **Horoscopes, listicles, product-roundup content.**
+
+### Explicitly NOT vetoed
+
+Connor is not anti-sport; he is anti *US-big-three-wire-recap*. These stay:
+
+- **Rock climbing, chess, the Olympics, oddball sports** — actively wanted.
+- **Soccer** — he is trying to get into it. Match previews and live threads are noise, but
+  the sport is not blocked as a concept. This is the first thing to loosen if soccer feels
+  under-covered.
+- **Sports governance and politics** — FIFA/UEFA corruption, Olympic host-city displacement,
+  Qatar migrant labour. These read as politics, not sport, and the old blocklist's
+  collisions with them were a bug.
+
+## The importance lane
+
+Independent of interest. This is the "I need to know this even though it isn't my topic"
+channel, and it is half the reason the project exists. Its own small daily budget.
+
+- War and escalation — new military action between states, major escalation in an ongoing
+  conflict, nuclear or WMD events.
+- Mass-casualty events and disasters — earthquakes, major attacks, industrial and transport
+  catastrophes.
+- US federal shocks — constitutional crises, major Supreme Court rulings, shutdowns, sudden
+  sweeping policy moves.
+- Economic breaks — market crashes, bank failures, currency crises, central bank surprises.
+- Major US political events — significant election results, deaths of political figures.
+
+**Vetoes still apply on this lane.** In v0.2 the bypass lane ignored relevance entirely
+(`gate.rs:302`), so a blocklisted item could still fire at priority 5. That must not recur.
+
+## Delivery
+
+- 2–5 pushes per day total, across both lanes. High bar.
+- The daily digest is a **web page**, not a push payload. v0.2 sent a long markdown blob that
+  ntfy turned into a `.md` attachment, which is miserable to read on a phone. The push is
+  three lines and a link.
+- ntfy feedback buttons **must work**. They never have — `NEWS_API_BASE_URL` was unset, so
+  they were silently dropped at boot. That is the entire training signal for everything above.
+
+## Open questions
+
+- Digest hour, and the exact quiet-hours window.
+- Whether the importance lane may ever override quiet hours, and at what score.
+- Whether "Global South" is a real standing interest or an artifact of a small sample.
