- Never-nester: early returns over deep nesting
- Don't throw; model failures as values (One function (e.g., raise_public) maps error union to existing public exception contracts via exhaustive match + assert_never)
- No mutation; don't reassign variables, global or local. Instead of mutable lists and dicts, prefer tuples, frozen dataclasses (with slots=True), `MappingProxyType`, etc.
- Annotate every variable with `: Final` (LIT010). Unpacking and walrus targets cannot carry the annotation, so they are implicitly final. Don't rebind them.

parameter (``socket_timeout`` included), which silently emptied this allowlist and
dropped the socket timeouts from url-configured connections. ``inspect.unwrap``

``/indexes/``. The matcher is substring-based, so an index name may
itself contain a read fragment (an index named ``analyze*`` puts

recreate instead of racing to kill each other's fresh engine. We pass
`force_recreate` so the reconnect skips its `SELECT 1` liveness probe:
the connection is healthy here, it is the prepared statements on it
that are stale, so a passing probe would otherwise skip the recreate
and leave the retry to hit the same error. We then retry the identical
query exactly once.
The retry reuses the original query byte-for-byte. Mutating the SQL
(e.g. injecting a unique comment) would defeat PostgreSQL's plan cache,
forcing a fresh plan on every request and pegging the database CPU.
If the reconnect is skipped because a recent reconnect is still within
its cooldown, the retry runs against the same connection and may fail
again; the get_data backoff decorator re-runs the lookup and a later
attempt reconnects once the cooldown elapses.
The reconnect cooldown must not gate the engine this query itself saw
as stale, or a migration landing within the cooldown of an earlier
reconnect leaves auth failing until it elapses. The engine observed
before the query names it, so the reconnect bypasses the cooldown only
while that same engine is still the live one.
It is observed from `read_db`, not `writer_db`: `query_first` is a
top-level read, so with a read replica configured it runs on the reader
and it is the reader's prepared statements that went stale. Naming the
writer here would let an unrelated writer reconnect re-arm the cooldown
while the reader stayed poisoned.

Whether the reconnect cooldown should still gate this caller.
The cooldown collapses a burst of callers onto one recreate, so it
keeps gating a caller whose named engine has already been replaced:
that recreate is the one it was waiting for. While that engine is still
the live one the damage is still being served, so deferring to an
unrelated reconnect's cooldown would leave it broken until the cooldown
elapses.
A named engine always describes the one that served the failing read
(see `_query_first_with_cached_plan_fallback`), so it is compared
against `read_db`, identity included: `read_db` can resolve to a
different wrapper than it did at observation time.
The waiver is withdrawn once a repair of this same engine has been
tried and failed. A failed recreate leaves the generation where it was,
so without this every queued caller would still see its own engine live
and run its own full recreate serially instead of collapsing onto one
attempt, which is what the cooldown is for. The record is scoped to the
engine rather than to a global failure count: an unrelated reconnect
failing somewhere else says nothing about whether this engine can be
repaired, and gating on it would suppress the recovery this method
exists to allow.
The record is never cleared, and does not need to be. Generations are
monotonic per wrapper, so once the engine is repaired every later
caller names a higher one and the entry can never match again. And this
method is only ever the first half of the gate: the cooldown window
itself still expires, so an engine that can never be repaired degrades
to the plain cooldown rather than being suppressed forever.
