The 5-second checkpoint ran in TRUNCATE mode, which waits up to the
5-second busy timeout for every open read while holding the database
lock every batch write needs. It now runs in PASSIVE mode, which never
waits. A WAL file over 64 MiB instead gets one TRUNCATE checkpoint whose
wait for reads is capped at 500 ms and logged; it empties the file once
no read is open, and while reads follow one another with no pause it
can give up every time. A checkpoint that leaves part of the WAL
uncopied returns ErrCheckpointIncomplete, which the maintainer logs as
incomplete instead of completed. The writing connection's
journal_size_limit is 64 MiB.

The test and build stages move from golang:1.24-bookworm, a release
line that no longer gets security fixes, to golang:1.27.2-bookworm,
pinned by digest. The go directive in go.mod moves from 1.24.4 to
1.27.1, the Go in the pinned lint image, so no stage downloads another
toolchain. One test starts its goroutine with sync.WaitGroup.Go, which
the linter asks for once the module targets Go 1.25 or later.

The live route tables lose their random UUID key; the row id the
prefix-length sample draws is declared as the integer key. The prefix
tables are keyed by prefix and keep only first_seen; a batch inserts only
prefixes not stored yet. A route update sets only the columns that
change. Each kept index names the queries using it. Every write goes
through one connection kept for writing, with a 1 GiB page cache; reading
connections get 16 MiB, heap limits rise to 1.5 and 2 GiB (README
"Memory"). Batch writes go in key order. A benchmark run by hand writes
250,000 updates on 5 million routes faster than the feed's 10,000 a
second; a live run follows.

The database maintainer ran Vacuum and Analyze without the database lock
every batch write holds, so on the live feed every incremental vacuum
failed with "database is locked", and an hourly ANALYZE made a batch write
fail and lose its updates. Vacuum, Analyze and Checkpoint now take that
lock, so maintenance and batch writes wait for each other. Analyze runs
PRAGMA optimize with an analysis limit, which analyzes only tables whose
size changed a lot, so it holds the lock briefly however large the file.

A path ending in an AS set, such as [64496, 64497, [64498, 64499]], was
flattened into the sequence, so the route was stored as originated by the
last set member and the peering handler recorded peerings the path does not
show. ASPath now keeps the sequence and a trailing set of several members
apart; Origin() gives the last AS of the sequence, or 0 (no known origin)
for such a set. The handlers use it; peerings come from the sequence only.
The pages show origin 0 as no known origin, and the IP lookup asks no WHOIS
lookup for it. Empty paths are unchanged.

Takes .golangci.yml, .dockerignore, .gitignore, .editorconfig, the
workflow and REPO_POLICIES.md from sneak/prompts 0653579, with this
repository's own entries after the shared content. Lint (golangci-lint
v2.14.0) and test are Dockerfile phases that script/lint and script/test
build alone with a new CACHEBUST value, keeping Go's and golangci-lint's
caches; the image build depends on both. make fmt and make fmt-check also
format the markdown with prettier, pinned in yarn.lock. The agent
guidance moves to AGENTS.md. The Go code is fixed for what the new
configuration finds, and the AS and prefix detail reads now return the
rows' error after their loops.
