Provider-agnostic LLM registry, config check, migration runbook
[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; verified fmt/clippy(-W dead_code)/test green.

`[providers.<name>]` registry (`kind = openai | anthropic`, `base_url`, `model`, `effort`,

client and one ceiling). `LlmClient::for_provider(name, &cfg, ..)` dispatches on `kind`;

`Llms::from_config(&config, prompt, &meters)` builds the roles; `editor_or_bulk()` degrades
|

to bulk when the editor client is missing or its meter is tripped. One `UsageMeter` per

# Runbook — upgrading the server from v1 to curation v2
|
||||
|
||||
**Written:** 2026-09-02, for the `curation-v2` branch (all seven plan steps plus the provider
|
||||
registry). Every command below is meant to be run on the server, as `root` via `sudo`, unless it
|
||||
says otherwise. Expect the whole thing to take about an hour, most of it waiting on the embedding
|
||||
backfill and one dry run.
|
||||
|
||||
What changes for the operator, in one paragraph: the binary is replaced; the SQLite schema gains
|
||||
tables and drops `ratings`, `feed_priors` and `scores` (the migration copies your ratings first);
|
||||
`config.toml` loses a few keys and gains the `[llm]` / `[providers.*]` registry plus a
|
||||
`profile_path`; the env file gains two API keys and renames the DeepSeek one; a hand-maintained
|
||||
`profile.md` is installed next to the OPML; the systemd units are unchanged.
|
||||
|
||||
## 0. Before touching the server
|
||||
|
||||
On the dev box:
|
||||
|
||||
```sh
|
||||
git checkout curation-v2
|
||||
cargo test # expect green
|
||||
cargo build --release # or build on the server, as you do today
|
||||
```
|
||||
|
||||
The crate uses `edition = "2024"` and let-chains, so the server's toolchain must be current
|
||||
(`rustup update stable`). Read `data/profile.md` once; it is the reader profile you will be
|
||||
editing by hand from now on, and the first thing to tune when the paper feels off.
|
||||
|
||||
## 1. Freeze the timer, back everything up
|
||||
|
||||
```sh
|
||||
sudo systemctl stop daily-epub-generate.timer daily-epub-generate.service
|
||||
sudo systemctl stop daily-epub.service # the server also runs migrations on start
|
||||
|
||||
sudo install -d -m0750 -o daily-epub -g daily-epub /var/lib/daily-epub/backup
|
||||
sudo -u daily-epub sqlite3 /var/lib/daily-epub/daily-epub.db \
|
||||
".backup '/var/lib/daily-epub/backup/daily-epub-pre-v2-$(date +%F).db'"
|
||||
sudo cp -a /etc/daily-epub/config.toml /etc/daily-epub/config.toml.v1
|
||||
sudo cp -a /etc/daily-epub/env /etc/daily-epub/env.v1
|
||||
sudo cp -a /usr/local/bin/daily-epub /usr/local/bin/daily-epub.v1
|
||||
```
|
||||
|
||||
`.backup` is the safe way to copy a WAL-mode database; a plain `cp` while anything is open can
|
||||
miss the WAL. The migration is one-way (`ratings` is dropped after being copied), so this backup
|
||||
is the rollback path.
|
||||
|
||||
## 2. Install the new binary
|
||||
|
||||
```sh
|
||||
sudo install -m0755 target/release/daily-epub /usr/local/bin/
|
||||
daily-epub --version
|
||||
daily-epub --help # confirm `config`, `stats`, `explain`, `ratings`, `features` exist
|
||||
```
|
||||
|
||||
Do **not** start any service yet: every subcommand except `config check` opens the database and
|
||||
applies pending migrations, and you want the config right first.
|
||||
|
||||
The units in `systemd/` did not change. If you want to be sure your installed copies match:
|
||||
|
||||
```sh
|
||||
diff systemd/daily-epub-generate.service /etc/systemd/system/daily-epub-generate.service
|
||||
diff systemd/daily-epub.service /etc/systemd/system/daily-epub.service
|
||||
```
|
||||
|
||||
## 3. Edit `config.toml` in place
|
||||
|
||||
Everything you do not mention keeps its documented default, so the edit is small. Open it with
|
||||
`sudo -e /etc/daily-epub/config.toml` and apply this checklist.
|
||||
|
||||
**Remove** (each one now fails loudly at startup, naming its replacement):
|
||||
|
||||
| Old key | Why |
|
||||
|---|---|
|
||||
| `prefilter_keep = …` (top level) | replaced by `curation.ranking.deep_keep` (default 120) |
|
||||
| `max_daily_usd = …` (top level) | now per provider: `providers.deepseek.max_daily_usd` |
|
||||
| the whole `[deepseek]` table | becomes `[providers.deepseek]` + `[llm]` (see below) |
|
||||
| any `[anthropic]` table (only if you added one from an interim build) | becomes `[providers.anthropic]` |
|
||||
|
||||
**Add** near the top, next to `interests_opml`:
|
||||
|
||||
```toml
|
||||
profile_path = "/var/lib/daily-epub/data/profile.md"
|
||||
```
|
||||
|
||||
Use an absolute path. The default is `data/profile.md` *relative to the working directory*, which
|
||||
under the unit is `/var/lib/daily-epub`, so the default would resolve to the same place, but an
|
||||
explicit path survives running one-off commands from another directory. Point
|
||||
`interests_opml` at an absolute path too if it is still relative.
|
||||
|
||||
**Add** the LLM registry. Carry over the `base_url`, `model` and `price_*` values from your old
|
||||
`[deepseek]` table if you had changed them; the values shown are the defaults.
|
||||
|
||||

|
||||
price_output_per_mtok = 3.75 # includes thinking tokens; $7.50 from 2027-01-01

||||

|
||||
|
||||
**Leave alone** `[miniflux]`, `[server]`, `[publish]`, `[xtc]`, `[world]`, `[curation]
|
||||
sections`, `always_include_feeds`, `blocked_domains`. `[voyage]`, `[editorial]`,
|
||||
`[curation.feedback]` and `[curation.ranking]` all have sensible defaults; copy a section from
|
||||
`config.example.toml` only when you want to change a value in it.
|
||||
|
||||
## 4. Edit the env file
|
||||
|
||||
```sh
|
||||
sudo -e /etc/daily-epub/env
|
||||
```
|
||||
|
||||
| Variable | Action |
|
||||
|---|---|
|
||||
| `DAILY_EPUB_DEEPSEEK__API_KEY` | **rename** to `DAILY_EPUB_PROVIDERS__DEEPSEEK__API_KEY` (the old name is rejected at startup so it cannot silently disable the bulk model) |
|
||||
| `DAILY_EPUB_PROVIDERS__ANTHROPIC__API_KEY` | add |
|
||||
| `DAILY_EPUB_VOYAGE__API_KEY` | add |
|
||||
| `DAILY_EPUB_PROVIDERS__GEMINI__API_KEY` | add only if you configured `[providers.gemini]` |
|
||||
| `DAILY_EPUB_MINIFLUX__API_KEY`, `DAILY_EPUB_SERVER__HMAC_SECRET` | unchanged |
|
||||
|
||||
Keep it `0600 daily-epub:daily-epub`. Then set hard spend limits in the DeepSeek, Anthropic and
|
||||
Voyage dashboards: the in-app `max_daily_usd` meters are runaway guards, not accounting.
|
||||
|
||||
## 5. Install the reader profile
|
||||
|
||||
```sh
|
||||
sudo install -d -m0750 -o daily-epub -g daily-epub /var/lib/daily-epub/data
|
||||
sudo install -m0640 -o daily-epub -g daily-epub data/profile.md /var/lib/daily-epub/data/profile.md
|
||||
# if the OPML is not already there:
|
||||
sudo install -m0640 -o daily-epub -g daily-epub data/scour-interests.opml /var/lib/daily-epub/data/
|
||||
```
|
||||
|
||||
If the file is missing the run does not fail; it logs a warning and uses the OPML interests only,
|
||||
which is a much worse prompt. `config check` in the next step tells you whether it was found.
|
||||
|
||||
## 6. Check the config as the service user
|
||||
|
||||
The units run as `daily-epub` with the env file loaded, so check the same way. This helper runs
|
||||
one command in that identity, with the env file and the working directory the unit uses, and no
|
||||
other hardening:
|
||||
|
||||
```sh
|
||||
de() { sudo systemd-run --quiet --wait --pty --collect \
|
||||
--uid=daily-epub --gid=daily-epub \
|
||||
-p WorkingDirectory=/var/lib/daily-epub -p EnvironmentFile=/etc/daily-epub/env \
|
||||
/usr/local/bin/daily-epub --config /etc/daily-epub/config.toml "$@"; }
|
||||
|
||||
de config check
|
||||
```
|
||||
|
||||
Expected: every line is a fact, no line starts with `!`. Fix anything marked `MISSING` (a key
|
||||
name, a path) before continuing. A stale key in the TOML is reported as an error naming its
|
||||
replacement; go back to section 3.
|
||||
|
||||
## 7. Migrate the schema
|
||||
|
||||
```sh
|
||||
de db migrate
|
||||
sudo -u daily-epub sqlite3 /var/lib/daily-epub/daily-epub.db '.tables'
|
||||
# expect rating_events, article_embeddings, interest_embeddings, article_assessments,
|
||||
# candidate_runs; no ratings, feed_priors or scores
|
||||
sudo -u daily-epub sqlite3 /var/lib/daily-epub/daily-epub.db \
|
||||
"select label, count(*) from rating_events group by label;"
|
||||
# your old votes: up → loved, down → not_for_me, source = 'migration'
|
||||
```
|
||||
|
||||
## 8. Warm the embedding cache, then a dry run
|
||||
|
||||
```sh
|
||||
de features backfill --rated-only # the learned set; prints a token estimate first
|
||||
de features backfill --days 30 # recent articles, so day one is not all cache misses
|
||||
de generate --dry-run --out /var/lib/daily-epub/out-check
|
||||
```
|
||||
|
||||
The dry run makes real DeepSeek, Claude and Voyage calls but publishes nothing and writes no
|
||||
`issues` row. Read the printed lineup and the four report lines (`curation:`, `admission:`,
|
||||
`preference:`, `providers:`); the cost should be well under $1. Then read the EPUB it wrote
|
||||
(Calibre or KOReader): The Brief, the `Why it's here` line under each headline, and the new
|
||||
Behind-the-paper chapter before the colophon. Finally:
|
||||
|
||||
```sh
|
||||
de explain --date "$(date +%F)" --near-misses
|
||||
```
|
||||
|
||||
Remove `/var/lib/daily-epub/out-check` when done.
|
||||
|
||||
## 9. Go live
|
||||
|
||||
```sh
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl start daily-epub.service
|
||||
sudo systemctl enable --now daily-epub-generate.timer
|
||||
sudo systemctl list-timers daily-epub-generate.timer
|
||||
```
|
||||
|
||||
If you want today's paper regenerated by the new pipeline now rather than tomorrow at 05:30:
|
||||
`sudo systemctl start daily-epub-generate`. A same-date rerun replaces today's issue and is a
|
||||
new run id in telemetry.
|
||||
|
||||
Afterwards:
|
||||
|
||||
```sh
|
||||
journalctl -u daily-epub-generate -n 60 --no-pager # the four-line info block near the end
|
||||
de stats --days 14
|
||||
```
|
||||
|
||||
## 10. Comparing editors (Claude Opus 5 vs Gemini 3.8 Flash)
|
||||
|
||||
With `[providers.gemini]` and its key in place, an A/B needs no config edit: environment variables
|
||||
override the TOML, so
|
||||
|
||||
```sh
|
||||
sudo systemd-run --quiet --wait --pty --collect --uid=daily-epub --gid=daily-epub \
|
||||
-p WorkingDirectory=/var/lib/daily-epub -p EnvironmentFile=/etc/daily-epub/env \
|
||||
-E DAILY_EPUB_LLM__EDITOR=gemini \
|
||||
/usr/local/bin/daily-epub --config /etc/daily-epub/config.toml \
|
||||
generate --dry-run --date "$(date +%F)" --out /var/lib/daily-epub/out-gemini
|
||||
```
|
||||
|
||||
produces the same date's paper with Gemini as the editor. Triage and deep assessments are cached
|
||||
for three days, so the second run costs only the editor, summaries and the Brief. Compare the two
|
||||
lineups, the `why` lines and the Brief side by side, and the `providers:` cost line. To switch
|
||||
for good, set `editor = "gemini"` in `[llm]` (and `summary_model` stays `editor`, so summaries
|
||||
move with it). The same trick works for the bulk role: `DAILY_EPUB_LLM__BULK=gemini`.
|
||||
|
||||
## Rollback
|
||||
|
||||
```sh
|
||||
sudo systemctl stop daily-epub-generate.timer daily-epub.service
|
||||
sudo install -m0755 /usr/local/bin/daily-epub.v1 /usr/local/bin/daily-epub
|
||||
sudo cp -a /etc/daily-epub/config.toml.v1 /etc/daily-epub/config.toml
|
||||
sudo cp -a /etc/daily-epub/env.v1 /etc/daily-epub/env
|
||||
sudo -u daily-epub cp /var/lib/daily-epub/backup/daily-epub-pre-v2-<date>.db /var/lib/daily-epub/daily-epub.db
|
||||
sudo rm -f /var/lib/daily-epub/daily-epub.db-wal /var/lib/daily-epub/daily-epub.db-shm
|
||||
sudo systemctl start daily-epub.service daily-epub-generate.timer
|
||||
```
|
||||
|
||||
The database restore is required, not optional: the v1 binary expects `ratings`, `feed_priors`
|
||||
and `scores`, which v2's migrations drop.
