The plan review caught three mistakes that would have gone red in the
tests rather than in the implementation. Column counts: COLUMNS is the
insert field list and excludes the database-filled created_at, so a
stale table has 23 physical columns and a current one 25, not 22 and 24.
Warning capture: the library logs through loguru, which never reaches
caplog, so that assertion would have passed forever without seeing a
single line. And the stale-table-under-least-privilege fixture is
least_privilege_pre_tenant_dsn -- the other one builds a complete table
and never reaches the missing-column path at all.
Three more: make lint rewrites files, so verification uses make check;
the recorder signature change now ships with its only call site instead
of leaving a TypeError between two commits; and the backfill statements
the library runs are not the ones it prints -- the library probes first
to dodge the exclusive lock, while a script handed to a DBA has to carry
IF NOT EXISTS or it cannot be run twice.
On the cap side, all three clients build their emitter inside __init__,
so a required parameter there would strand anyone constructing a client
directly. The emitter stays required, the clients take a defaulted one.
Twelve tasks across the two plans, each with the files it touches, the
evidence it has to produce, and the command that proves it. #13 goes
first: both branches edit config.py and client.py, and #12's
partitioning template leans on the schema SQL helper and the untargeted
conflict clause that #13 introduces.
Writing the cap plan surfaced a trap worth its own guard. digest_messages
appends the very same dict when a message's content is not a list, so
the telemetry copy, the caller's messages and the cache key all share
one object -- capping in place would poison the caller's request and the
cache key at once, silently. Two red-line tests now pin that down, and
the plan asks for an in-place version to be written and run first, to
prove the tests actually catch it.
