 The Feb 2025 consumer-keyed layout (`lecture-python-intro/{static,dynamic,scripts}/`) was flattened into this tree on 2026-07-16, while nothing referenced the repo.
 
-**That freedom is now spent.** The restructure was free only because zero lectures pointed here; as soon as the first repoint merges (PLAN Phase 8), every move or rename in `lectures/` is a breaking change for a live lecture build. From that point on, treat published filenames as an API: corrections in place, new vintages under new names, and check `consumers` before touching anything.
+**That freedom is now spent — the repo is live.** The first repoint merged on 2026-07-17 (P1: `msy_fishery` in lecture-python-intro reads `lectures/lingcod_msy_recovery.csv` from `raw/main`), so every move or rename in `lectures/` is a breaking change for a live lecture build. Treat published filenames as an API: corrections in place, new vintages under new names, and check `consumers` before touching anything. Enforced by the `protect-main` ruleset (PRs only, no force-push, and the `consumed-files` check is **required** — a PR that breaks a consumed file cannot merge).

 - [x] Branch protection on `main`: PRs required (no direct pushes; zero approvals so a solo maintainer can still merge), force-pushes and deletion blocked. Once a lecture repoints, `raw/main` is a production URL and an accidental force-push is a lecture outage (ruleset added 2026-07-17)

 The first end-to-end deployment: one dataset per hosting pattern, each the hardest representative of its class, carried through the full chain — layout, manifest, integrity check, publish, lecture repoint. Validates the convention empirically before anything is written into a standard. Sequence P1 → P2 → P3 → P4, each a small PR set (data repo + consuming lecture repos).

Tests: single-PR green build under `-nW`, Colab-unchanged download, catalog metadata for an author-assembled file. **Complete 2026-07-17** — data half #12, repoint QuantEcon/lecture-python-intro#792 (lecture build green in the single repoint PR); served URL verified byte-identical to the manifest `sha256`; Colab holds by construction (the lecture now reads a public URL, where the old relative path was exactly what broke downloaded notebooks); metadata findings recorded in meta#338. **The repo is live from this merge** — the pyodide/CORS check below remains open
 - [ ] **P2 — cross-series shared static**: the `pandas_panel` trio (`realwage.csv`, `countries.csv`, `employ.csv`), consumed by programming **and** python.myst. Tests: flat namespace with two consuming series, one data PR updating two lecture repos; retires 5 of the 8 legacy-repo references as a side effect
 - [ ] **P3 — external-repo static with LFS**: the `heavy_tails` set (Forbes ×2, cities ×2) plus the SCF pair from `high_dim_data`. Tests: served URL makes the raw-vs-media LFS trap invisible, Pages handles LFS objects (`lfs: true`), builders (`webscrape_forbes.ipynb`, `generating_mini.md`) migrate alongside their data
 - [ ] **P4 — dynamic snapshot twin**: `UNRATE`, consumed today by 4 lectures across 3 repos via 2 access methods. Tests: the full dynamic template — manifest, four-stage builder, refresh-as-PR, canary catching an induced failure — plus the documented live-call ↔ snapshot switch mechanism
