Every write now uses one connection taken from the pool when the
database opens, under the database lock. Its 1 GiB page cache keeps
the pages the route writes touch from one batch to the next. A reading
connection's cache is emptied whenever another connection has written,
so the 9 reading connections drop to 16 MiB each. The soft and hard
heap limits rise to 1.5 and 2 GiB, above the caches; README "Memory"
adds up the new budget. Vacuum, Analyze and Checkpoint check their
context after the lock, which the kept connection does not. Batch
writes sort their rows by peer, then prefix. The benchmark also times
the largest prefix handler batch, 250,000 updates.

The live route tables lose their random UUID key: the row id, which the
prefix-length sample draws, is now declared as the integer key. The prefix
tables are keyed by the prefix, without the UUID or the duplicate index.
A route update sets only the columns that change, so SQLite no longer
rewrites the mask length indexes on every update, nor the origin index
while the origin AS stays the same. Each kept index names the queries
that use it. BenchmarkPrefixBatchOnFiveMillionRoutes, run by hand, times
one 25,000-update batch on 5 million routes.
Model: opus-5-5
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.
