P2 of the logging plan (the README recipe landed with the code change):
- `docker-compose.yml.example`: one `x-logging` anchor applied to all three
services. json-file grows without limit by default, so a long-running bot
and the proxy in front of it fill the disk; capped at 10m × 3 files.
- The startup `config:` line now reports what the process actually resolved —
the state DB path (a mistyped `DATA_DIR` or a surprising CWD was invisible
until it bit), both TTLs, the caption-quote setting (`off` rather than a bare
`0`) and whether a proxy is configured. The proxy URL is never printed (it
may embed credentials) and admin ids — chat identifiers — stay at `debug`.
Verified: `docker compose config -q` accepts the file, and a scripted fake-API
run shows `caption quote off` / `link cache TTL 3600s` under overrides,
`proxy=yes` with no credential in any line, and the ids at `debug` only.
The DB file was hardcoded to CWD-relative data/task_queue.db — a footgun
for systemd/cron deployments and a confusing startup failure when the
data/ dir did not exist (SQLite never creates parent dirs).
db_path() now reads DATA_DIR (default data, CWD-relative, unchanged for
local runs and the docker-compose ./data mount) and creates the
directory automatically. README/README.en.md env tables and AGENTS.md
document the new variable.
