deploy-hub.yml builds deploy/hub/Dockerfile on the appserver runner, writes
.env from repo secrets and starts docker-compose.prod.yml (external
PostgreSQL, /data bind-mounted), then polls /health.
ci.yml used runs-on: docker, which no runner has, so jobs never started.
Build/tests and the MSI now run inside the SDK image via deploy/ci/Dockerfile,
because the host-mode runner ignores container: and has no apt-get.

installer/SQLInsight.wxs (WiX 3 syntax) builds on Linux with wixl
(installer/build-msi.sh) and in Forgejo CI on every v* tag. Agent and Web
are installed self-contained as Windows services under virtual service
accounts (or a gMSA), with a settings page in the wizard or MSI
properties for silent installs; the values go to sqlinsight.ini, read
after appsettings.json. The data folder is locked to SYSTEM,
Administrators and the agent account, the event log source is
registered, the web port is opened in the firewall, and the automatic
update task is an optional feature. Upgrades happen in place, keep
edited settings and the chosen features; uninstall keeps the settings.
msi-tables.py writes what wixl lacks (component and feature conditions,
Permanent/NeverOverwrite, vital services, REG_EXPAND_SZ) and
verify-msi.py checks the result (sequencing, deferred actions, ASCII
only). test-msi-wine.sh runs install, upgrade and uninstall under Wine.
Installations made with the MSI get new versions as MSI packages run by
the update task, so Windows Installer stays in charge of the files.
The example instance is removed from the shipped appsettings.json, and
the CLI writes UTF-8 to the console.

The hub records when an instance changes build and works out which
findings went away within three days of an update and which were still
there a week later (version rules excluded). Staff see every effect in
the portal; effects seen at three or more customers, resolved more
often than not, are served to licensed agents as anonymous counts
(rule, major version, build, CU, customers, instances). The agent
fetches them every six hours and the web UI shows them on matching
findings: 'at 3 customers this went away after updating to CU21'.
Data processing documentation covers the aggregation.

Rules can now be data: a JSON file with one read-only SELECT where every
row is a finding, with {column} templates, server or per-database scope,
minimum version, sensitive columns and references. Community rules live
in rules/community (reviewed via pull request), ship with every build
and with the signed rule pack; local rules are read from the agent's
data folder every five minutes. Queries are checked for anything that
could write, run with the least-privilege login, and a missing
permission makes the rule not measurable rather than failing. The
rule engine picks up catalog changes without a restart. Authors get
'rules validate' and 'rules test --instance'. Four example community
rules (sa active, orphaned database owners, default trace off,
untrusted foreign keys).

A PDF report for management and auditors (PDFsharp/MigraDoc, MIT, with
the Inter font embedded): key figures, a plain-language summary,
compliance controls backed by rules (met, not met, not measured),
instances and the critical and high findings. Downloadable from the
web UI (/rapporter) and mailed monthly by the agent with the PDF
attached, once per month, across daylight saving changes.

Hub: nightly retention of resolved findings, the submission log and
silent instances; delete-customer erases a customer's data and blocks
its licenses; persistent data protection keys and trusted reverse
proxies. Docker image and compose file with PostgreSQL. The agent
refuses to send the license to a non-https hub. Documentation for the
hub, for data processing (GDPR basis for a data processing agreement)
and the README roadmap for phase 3.

Rule packs (support dates and newest CU per release) are published in a
signed feed and hot-loaded without a restart; the verified pack is
reloaded at startup. New versions are announced (Notify) or downloaded
and staged by the unprivileged agent (Automatic), and installed by a
privileged apply-update task that re-verifies signature and hash in an
admin-only folder, keeps appsettings/web.config, health-checks the
services and rolls back on failure. Stable and preview channels,
manifest expiry and rollback protection, https or folder/share feeds
for offline sites. Vendor tool gains rulepack and publish; the Hub can
serve the feed; the web UI gets a System page with update, rule pack,
license and exactly what is sent to the Hub.

- ASP.NET Core API POST /api/v1/findings with EF Core (Npgsql, snake_case)
and a generated initial migration
- The hub is the authority on licenses: verifies the signature itself,
rejects invalid (401), community/expired past grace (403), revoked
(403, re-checked under the lock) and over the instance limit (403)
- Full-state reconciliation per instance: new findings inserted, existing
updated, missing ones resolved, rule states upserted; idempotent by
submission id; late older submissions are recorded but not applied
- Serialized per customer with a PostgreSQL advisory lock (found by a
concurrency test: parallel first submissions raced on the license row)
- Size and schema validation; tests on real PostgreSQL, including the full
path agent → queue → hub → PostgreSQL with evidence redaction

- Evidence can be marked sensitive (query text, logins, hosts, programs,
job error messages); rules mark it. Sensitive values and the server
name are sent as [udeladt] unless the customer allows them.
- Full-state submission contract (all active findings and rule outcomes
per instance), idempotent by submission id
- Local outbound queue in the repository (migration 0002): newest state
per instance only, exponential backoff up to an hour, permanent
rejections (bad license, bad request) are given up, sent items purged
- Hub status (license state, last sent, last error) for the web UI
- Sync runs only with a valid license (or in grace); monitoring never
depends on it

- SQLInsight.Licensing: ECDSA P-256 signed documents (SQLI1.payload.sig),
licenses with plan, expiry, instance count and key id for rotation;
30-day grace; invalid or missing licenses are states, never errors,
and never stop monitoring (a license only adds hub sync and support)
- Trusted public keys are embedded; the source ships with none, so a
published key can never mint licenses. The vendor adds its own.
- tools/SQLInsight.LicenseTool: keygen, issue, verify
- *.private.pem ignored by git

newest engine with all capabilities; new SelfManagedInfrastructure
capability so backup, CHECKDB, files, tempdb, memory, patch level and
lifecycle rules report 'handled by Azure' instead of false findings
- Microsoft Entra ID login (managed identity, service principal, default
credential chain) via SqlConnection.AccessTokenCallback
- Least-privilege script recognizes Managed Instance; deadlock collector
falls back to the ring buffer when event files cannot be read
- Web UI shows the right release for Managed Instance
- README and installation docs: notifications and Managed Instance

unreachable/recovered transitions, with links to the web UI
- Channels: e-mail (MailKit, HTML-encoded), Microsoft Teams Workflows
webhook (Adaptive Card), generic JSON webhook signed with HMAC-SHA256
- Per-channel minimum severity (outages always sent), one message per
batch, hourly cap per channel; a failing channel never stops monitoring

Baselines per hour of the week (with neighbouring hours) from four weeks
of hourly aggregates, computed in C# (independent of DATEFIRST) and
refreshed by the agent each hour. SQLI-ANOM-001 compares current load
with what is normal at this time: CPU far above normal, batch requests
far above or collapsed (application down?), page life expectancy
collapse. Not measurable until enough history exists.

queues, commit times) and rules: SQLI-AG-001 unhealthy/disconnected
replica or suspended data movement (scripts HADR RESUME), SQLI-AG-002
secondary behind (estimated data loss and redo time)
- SQL Agent collector using only granted msdb tables (no EXECUTE on msdb
functions): SQLI-JOB-001 failed job with the failing step's message
(backup/CHECKDB jobs are High), SQLI-JOB-002 SQL Agent not running
- Integration tests create a real availability group (CLUSTER_TYPE NONE)
and a failing job in the test container (HADR and Agent enabled)

Collector (every 6 h, metadata and DMVs only, no scans): index inventory
with usage and forwarded fetches, missing-index suggestions, statistics
modifications via sysindexes.rowmodctr (needs only metadata visibility).
Rules:
- SQLI-IDX-001 missing index, evaluated against existing indexes:
extends an index with the same keys instead of adding one; notes on
write-heavy tables, many indexes, wide includes, short uptime
- SQLI-IDX-002 unused index (needs 7 days of uptime; suggests DISABLE)
- SQLI-IDX-003 duplicate or covered index (filters, uniqueness respected)
- SQLI-IDX-004 heap with forwarded records
- SQLI-STAT-001 stale statistics, SQLI-STAT-002 auto statistics off
Column lists use U+E000 as separator: FOR XML cannot serialize NCHAR(1).

Collector takes the 50 heaviest statements (CPU, last 24 h), fetches
statement plans as text (dm_exec_query_plan returns NULL for deeply
nested plans) and analyzes them in C#. Rules:
- SQLI-PLAN-001 implicit conversion preventing an index seek
- SQLI-PLAN-002 join without predicate (deliberate CROSS JOIN excluded)
- SQLI-PLAN-003 non-inlined scalar UDF in a heavy statement
- SQLI-PLAN-004 spills to tempdb, SQLI-PLAN-005 oversized memory grants
(2016 SP2+ / 2017 CU3+ columns, new capability)
Verified against real plans in SQL Server.

Collector reads the 100 heaviest queries per Query Store database, split
into the last 24 hours and the week before. Rules:
- SQLI-QS-001 plan regression: new plan >= 2x slower than the best plan
from the week before and >= 60 s extra per day; scripts the force
- SQLI-QS-002 forced plan that fails (e.g. NO_INDEX); scripts the unforce
- SQLI-QS-003 parameter sensitivity: very different plans or volatile
durations; suggests PSP optimization / Query Store hints on 2022+
Also: backups taken in the same second a database was created count.

- ASP.NET Core Blazor static SSR: overview with KPI tiles, instance page
(findings, CPU/batch/PLE trends, top waits, file latency, blocking,
deadlocks with .xdl download, not-measurable rules, resolved), finding
detail with explanation, evidence, fix script and references
- Light-first design (sidebar, cards, self-hosted Inter, teal accent),
optional dark theme via toggle; strict CSP, no inline styles
- Windows authentication (Negotiate/IIS) with optional group restriction;
refuses to run without authentication outside Development
- Hosting: IIS (in-process ASP.NET Core Module), Windows service with
Kestrel, or systemd; web reads the repository with db_datareader only
- docs/installation.md for repository, permissions, agent and web
- Fix: CPU used by other processes is not derived on Linux (SystemIdle is
unreliable there); deadlocks are not re-reported or stored twice after
an agent restart; Dapper sends datetime2 so time comparisons are exact

Each instance runs its due collectors over one hardened connection per
cycle, keeps previous results for deltas, evaluates all rules and stores
findings, rule states and time series. Instances run in parallel with a
limit; a slow or failing instance never delays the others. The
repository is migrated at startup with retry, and maintenance runs hourly.

- Versioned, embedded migrations serialized with sp_getapplock so the agent
and web UI can both migrate at startup
- Findings tracked per rule and subject: first seen, last seen, resolved;
a rule that could not run never resolves its findings
- Time series (waits, file I/O, CPU, counters), blocking chains and
deadlock graphs; idempotent inserts (timestamps truncated to match
datetime2(0)), hourly aggregation and batched retention deletes
- Read API for the web UI; integration tests against SQL Server

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.

All mainstream and extended support end dates checked against Microsoft
sources. SQL Server 2025 added (mainstream ends 2031-01-06, extended
