The origin was 3–8 ms per page, almost all of it per-statement overhead:
an issue page ran two statements per pick (~55 on a 25-article issue) and
every signed-in page wrote its session row back because `take_flash`
called `Session::remove`, which marks the session modified even when the
key is absent.
- `Db::get_articles` loads an issue's articles and their social rows in
two statements; both branches of `web::issue::load` use it. The
single-id and batch queries share one projection via a macro.
- `take_flash` reads before removing, and touches a signed-in session at
most once a day so the inactivity expiry still slides. Anonymous
requests never create a session.
- `Server-Timing: app;dur=<ms>` on every response, outermost layer.
- `reject_early_data`: 425 for a non-safe method that arrived as TLS 0-RTT
data, so nginx `ssl_early_data on` is safe (RFC 8470 §5.2).
- `[profile.release]`: fat LTO, one codegen unit (binary 46 → 29 MB).
Docs: the Cloudflare proxy was retired on 2026-09-05 after measuring
+43 ms per signed-in page from Boston; README reverse-proxy section is
now the direct setup (upstream keepalive, 0-RTT lines) and the CDN
runbook carries a retired-status banner.
Dev seed, app-side: `/` 21 → 5 statements, 3.7 → 1.0 ms; `/feed.xml`
44 → 12, 9.1 → 3.0 ms; session writes per signed-in page 1 → 0.

The first rollout put the cookie bypass rule above the cache rule, as
the runbook said to, and signed-in requests were served the cached
anonymous page. Cloudflare applies the last matching rule for each
setting. Fold the cookie exclusion into the cache rule's expression so
order stops mattering, and explain the symptom in the verify step.

The edge-purge integration was reverted in the previous commit; this
finishes the job. Public pages, the feed and /issues.json now say
`public, max-age=300` for browsers and shared caches alike, the code
comments and README explain why the longer s-maxage plus purge design
was dropped, and the rollout runbook loses its purge step, marks the
HTML cache rule optional, and warns to keep the record DNS-only until
the Universal SSL certificate is active.

The README's nginx snippet had drifted from the box: it was missing http2, the
security-headers include, the gzip block, the keepalive bump and the trusted
certificate. Replace it with what actually runs, then add the two CDN changes.
`set_real_ip_from` for Cloudflare's ranges plus `real_ip_header
CF-Connecting-IP` has to come first, or every request looks like it came from
Cloudflare and the login throttle becomes global. Then `X-Forwarded-For` is
*set* from `$remote_addr` rather than appended to: the throttle keys on the
first entry, so a client-supplied header must never survive into the app.
The ranges are listed for reference but the reader is told to regenerate them
from cloudflare.com/ips-v4 and /ips-v6, with a one-liner that does it.
The gzip comment claimed the stylesheet carries 445 KB of base64 fonts; it has
not since the faces moved back out to their own URLs.
The new runbook covers the order that matters: the DNS move (Free plan means a
full nameserver change, so the rest of the zone has to survive it), the zone
settings that are quietly wrong by default — Browser Cache TTL *raises* the
origin's max-age unless set to "Respect Existing Headers", and Rocket Loader and
Email Obfuscation both inject scripts the site's `script-src 'self'` CSP blocks
— the two cache rules, locking the origin to Cloudflare, wiring the purge token,
and the `cf-cache-status` checks that prove each row of the header matrix.

/static/app.css, app.js and theme.js URLs now carry the first 12 hex digits
of a SHA-256 over the embedded assets, so any CSS or JS change reaches
browsers that cached the previous build without a version bump.

Replaces the hand-written stylesheet with a Tailwind CSS v4 source
(src/web/tailwind.css) whose minified build is committed as
src/web/static/app.css and still embedded with include_str!, so the binary
and the test suite never need Node. package.json pins tailwindcss and
@tailwindcss/cli to 4.3.3 and adds css, css:watch and css:check.
Colours are semantic CSS variables swapped per theme and exposed to Tailwind
through @theme inline, so templates write bg-paper/text-ink/border-rule once
and both themes work. theme.js runs synchronously in <head> to set
data-theme before paint; app.js cycles the toggle system -> light -> dark and
persists the choice. Newsreader is self-hosted and served from
web::static_asset with the same ETag/304 logic as the other assets.
Every reader template is restyled: ears row, centred masthead with its rules,
tracked section labels, the drop cap on The Brief, "Why it's here" with its
accent bar, the segmented rating control, prev/next cards, and the colophon
as a two-column definition grid. Dashboard templates are untouched (step 3).
Also fixes a .block collision with Tailwind's display utility, the SVG
`hidden` property that never toggled the theme icon, and points the dev
seed's profile_path at ./dev so previewing cannot rewrite data/profile.md.

Users page, README and config.example updates, implementation notes, the
rollout runbook, site-layout 404/500 pages, human-readable download sizes,
dark-mode and narrow-screen polish, and a smoke test over every dashboard
route; also removes zdiff3 ancestor markers left by earlier merges.

DeepSeek's content filter rejects a whole request (400 "Content Exists
Risk") when one article trips it, which cost the other articles in the
batch their assessment and retried them every run. New curate/batch.rs
runs both stages through a bisecting runner: a rejected batch is split
until the offending article is isolated, that article is retried once on
the editor provider when it is a different one, and a still-rejected
article is recorded as a provider_rejected assessment row so it is not
retried for assessment_reuse_days. Cache reuse accepts rows from either
configured model. Each stage logs reused/requested/rejected counts, the
curation: line shows rejections when non-zero, explain prints them, and
the llm_assess span reports the deep-set size.

[llm] assigns the bulk and editor roles by name over a [providers.*]
registry (kind = openai | anthropic, per-provider model, effort, daily
ceiling and price table); DeepseekBackend becomes OpenAiCompatibleBackend
(reasoning_effort passthrough), AnthropicBackend builds from the same
ProviderConfig, meters and provider_costs are keyed by provider name.
Gemini 3.8 Flash is declared via Google's OpenAI-compatible endpoint so
switching the editor is one line (or DAILY_EPUB_LLM__EDITOR=gemini for an
A/B dry run). Stale [deepseek]/[anthropic] tables, the top-level
max_daily_usd and the old key env vars fail loudly.
daily-epub config check validates and prints the resolved roles, models,
key presence and paths without opening the database.
docs/runbooks/curation-v2-migration.md walks the server upgrade from v1.
Registry implemented by a Claude agent from an orchestrator brief;
