Pre-compact cleanup: CHANGELOG + archive

CHANGELOG.md

+# CHANGELOG
+
+## Sprint 1 — 2026-09-06 · the blog comes home
+
+### Added
+- `/blog` content section: unified remark→rehype pipeline in `lib/markdown.ts` (GFM, remark-directive escape-hatch stub for future Hydra/Strudel islands, shiki build-time highlighting via rehype-pretty-code, figure/caption centering), draft:true prod filtering with dev SHOW_DRAFTS, `/blog` index + `/blog/[slug]` SSG routes with generateMetadata/OG, fixture post `hello-world-again` — commits 8513a37, 87e54dd on feat/blog (#blog-1).
+- `yarn post <slug>` / `yarn post:image <slug> <file>` — new-post scaffold + image-drop helpers (#blog-2).
+
+### Changed
+- `content/posts` → `content/blog` (two 2021 entries demoted `draft:true`); `/post/[id]` route removed; remark/remark-html retired for the unified chain (#blog-1).
+- Static export: `output:'export'`, unoptimized images; the two parvagues `revalidate` ISR exports removed — rebuild-on-push replaces ISR (ratified) (#blog-3, 87e54dd).
+- Fixture image codec: 9.3M PNG → 145K 1600px JPEG (original kept in public/images) (#blog-4, 1ebd5f7, 6bc6419).
+
+### Fixed
+- Jest under Yarn PnP: `transformIgnorePatterns` now transforms the ESM-only unified chain (PnP cache zips carry `/node_modules/` segments, so the old exclusion skipped them) (#blog-5, 4ea7f05).
+- e2e smoke route `/post/hello-world` → `/blog/hello-world-again` (#blog-5).
+
+### Infra
+- Repo home = git.nech.pl/pln/www (origin flipped; github demoted to secondary `github` remote); 651M stray pre-hoist `next/` detritus deleted; main reconciled (7b5fdf9).
+- me.nech.pl cutover complete: erable nginx vhost (games/opal pattern), certbot --webroot, TLS enabled, HTTP 301, rsync deploy — HTTPS live, cert to 2026-12-05, renewal via certbot.timer (SRE e30cbc0 + TLS flip).
+
+### Doctrine
+- Blog content ships as neutral fixtures — prose is the owner's via git; no Claude-authored "draft in your voice" scaffolds (see memory `feedback_no-claudespeak-prose`).
+- Builder briefs carry: fixture-final clause, report-don't-fix clause, and the documented zero-test baseline means "No tests found" IS green.
