Built from the schema files in the SQL Server 2022 container and read as the
least-privilege agent login: detection and discovery, 'ikke målbar' with the
exact GRANT and measuring after it (no customer table readable, no data
changed), the shipped grant/revoke scripts, AX 2012 history by RECID read
once, a locked AX table skipped within seconds, the SQL Scripts run as-is,
repository retention and read-back, and the web pages and API v1.

CollectorContext carries the instance's DatabaseSelection; the database,
index, Query Store and community-rule collectors skip databases that are not
chosen (system databases always run). DatabaseDiscovery lists every database
with state, size, recovery model, compatibility level and access, and
recognises Dynamics AX with the same signature as the AX rules, through
three-part names only (2000 and 2005+ variants). PermissionCheck reports which
rights from grant-least-privilege.sql the login has (HAS_PERMS_BY_NAME,
version-aware; not possible on 2000).

Collectors (SQL Server 2000+, version-specific SQL, least privilege):
server, configuration, trace flags, databases (settings, backups in UTC,
CHECKDB, VLFs, Query Store, files, tempdb), suspect pages, plan cache,
wait stats and file I/O as deltas with restart/clear detection,
performance counters, CPU from the scheduler monitor ring buffer,
blocking (sleeping head blockers with open transactions), and deadlocks
from system_health continuing from the last file offset.
Rules: configuration (memory, MAXDOP per Microsoft NUMA guidance, cost
threshold, ad hoc bloat, risky options, pending changes), databases
(state, settings, backups, log backups, CHECKDB, suspect pages, VLFs,
autogrowth, max size, Query Store, tempdb), waits (THREADPOOL, signal
waits, locks, I/O, WRITELOG, parallelism, PAGELATCH), I/O latency, CPU,
memory grants, blocking and deadlocks. Missing data makes a rule not
measurable with the collector's reason.
Integration tests run every collector as the least-privilege login and
reproduce real blocking and a real deadlock; green on 2017 and 2022.
