…stently (v3.18.1)

When an endpoint is a proxy, all server-filled parameters now forward to
the upstream through one unified path: user claims, IP address, HTTP
Custom Type fields, and resolved-parameter expressions.

Placement mirrors the endpoint's own signature, NOT the HTTP verb:
- a @body_parameter_name param carries the raw request body;
- otherwise RequestParamType decides — QueryString appends to the proxy
  query string, BodyJson merges into the proxy JSON body (typed:
  numbers / booleans / embedded json / strings) when the method carries
  a body.

Additive: the verbatim incoming request is still forwarded; the
automatic params are added on top so the upstream receives the same
parameter set the routine would.

The previous claim/IP-only query append in BuildTargetUrl is removed and
folded into the unified mechanism. Behavior change: claims/IP now follow
RequestParamType (unchanged for GET/QueryString — still query; for
BodyJson endpoints they now go to the body).

Notes: body merge only for JSON content types (multipart/non-JSON
forwarded verbatim); only expanded per-field HTTP-type params forwarded.

Tests cover GET-query, POST-body (typed), param_type-query on POST, and
resolved-param forwarding; existing claim/IP proxy tests pass unchanged.
Full suite green (2288). See changelog/v3.18.1.md.

Also adds a Claude Code skill bundle (.claude/skills/npgsqlrest/) — a usage
guide plus full annotation and configuration references generated from
--annotations/--config — and a README section on installing it.

…er_name by any param name

Two fixes for proxy endpoints that forward auto-filled parameters (v3.18.1),
surfaced by combining @Proxy with an HTTP Custom Type parameter.

- ProxyOptions.MaxForwardedQueryParamLength (default 2048): a server-filled
  value longer than the limit is skipped with a warning instead of being
  percent-encoded into the upstream query string, which overflowed the request
  line (HTTP 414/431 / connection reset). Wired through Builder, ConfigDefaults,
  ConfigSchemaGenerator, ConfigTemplate, and appsettings.json.

- @body_parameter_name now matches case-insensitively and accepts any of a
  parameter's names. For an HTTP Custom Type field expanded from a composite,
  the converted name (responseBody), the expanded signature name
  (_response_body, via the new NpgsqlRestParameter.ExpandedName alias), and the
  shared base name (_response) all resolve. ActualName is unchanged so the
  fields still reassemble into the single composite SQL argument.

Tests: ProxyHttpTypeProbeTest adds converted-name redirect, expanded-name
redirect, and oversized-field-skipped cases. Full suite green (2291).

See changelog/v3.18.2.md. version.txt / npm not bumped yet.

…oints

The TypeScript client generator was broken for any endpoint using
@body_parameter_name:

- It emitted "body: request.<name>?" — the TS optional "?" suffix (added for
  parameters with a default or a custom type) leaked into the runtime property
  name, a syntax error. The query-exclusion key was likewise ["<name>?"], so the
  body parameter was not stripped from the query string. Now the bare converted
  name is used for both the body expression and the exclusion key.

- It emitted a fetch body even for GET, which fetch forbids. A body is now only
  emitted for methods that can carry one (not GET); a GET body parameter (e.g. a
  server-filled HTTP Custom Type field forwarded by a proxy POST) is simply
  excluded from the query and not sent.

- It matched @body_parameter_name only against the converted and actual names,
  so the expanded HTTP-type field name (e.g. _response_body) was ignored — the
  parameter leaked into the query and no body was emitted, even though the server
  resolved it. The generator now also matches the ExpandedName alias, consistent
  with the server-side body-parameter resolution.

Tests: NpgsqlRestTests/TsClientTests/BodyParamGetTests.cs covers a GET endpoint
(converted name) and a POST HTTP-Custom-Type endpoint targeted by the expanded
name _response_body. Full suite green (2293).

See changelog/v3.18.2.md. version.txt / npm not bumped yet.

…arams from generated requests

New opt-in option (default false) on TsClientOptions, HttpFileOptions, and
OpenApiOptions. When enabled, parameters that are filled by the server and
cannot be set by the client are omitted from the generated request shape:
the TypeScript request interface, the .http query string / JSON body, and the
OpenAPI query parameters / request body.

A parameter is omitted when it is automatic AND optional. The shared rule lives
on the core endpoint as RoutineEndpoint.OmitParameterFromGeneratedRequest, built
on RoutineEndpoint.IsAutomaticParameter, so all three generators stay consistent:

- always automatic: HTTP Custom Type fields, resolved-parameter expressions,
  upload-metadata parameters;
- automatic only when the endpoint uses user parameters: IP-address and
  user-claim parameters;
- optional guard: HasDefault or a composite/HTTP-type field, so omission can
  never make a required argument un-sendable.

When every parameter is omitted the request collapses cleanly: a no-argument
TypeScript function, a bare .http URL, and no OpenAPI parameters/requestBody.

Default is false to keep generated output byte-stable on upgrade; each generator
opts in independently. The option is wired through the client config for all
three plugins (binding, ConfigDefaults, schema, template, appsettings.json).

Tests: omission coverage for each generator (TsClientTests/HttpFilesTests/
OpenApiTests OmitAutomaticParamsTests), reusing the tsclient_test.bodyparam_*
HTTP-type fixtures with separate omit-enabled generator configs. Full suite
green (2299).

See changelog/v3.18.2.md. version.txt / npm not bumped yet.

…; unify body-param matching

The HTTP file and OpenAPI generators matched the @body_parameter_name parameter
with a case-sensitive Ordinal comparison against only the converted and actual
names. An HTTP Custom Type field targeted by its expanded name (e.g.
_response_body) was therefore not recognized as the body parameter: it stayed on
the query string instead of being moved into the request body. (The TypeScript
client and the server were already fixed; these two generators had drifted.)

Body-parameter resolution is now a single shared rule, RoutineEndpoint.
IsBodyParameter(param) — case-insensitive, matching the converted, actual, or
expanded per-field name. Every call site routes through it: the proxy forwarder,
the request-handling body branch, and the TypeScript, HTTP file, and OpenAPI
generators. No more re-inlined three-name comparisons to drift.

Tests: HttpFilesTests/BodyParamToBodyTests and OpenApiTests/BodyParamToBodyTests
assert that an expanded-name body parameter is emitted as the request body (not
the query) in both generators. Full suite green (2301).

…malLevels Off

SQL test runner (--test) — WIP, not yet in changelog (still stabilizing):
- Discovers *.test.sql, runs each on its own non-pooled connection, invokes
  endpoints in-process on the test's own connection/transaction, asserts via
  boolean SELECTs / DO blocks / `# @expect-status`. Captures responses into
  per-block pg_temp tables.
- Per-assertion reporting (each boolean SELECT / DO block / expect-status HTTP
  step is one test); console grouped per file, JUnit one <testcase> per assertion.
- Dedicated `NpgsqlRestTest` log channel (configurable TestRunner.LoggerName,
  leveled independently via Log:MinimalLevels): discovery/parsing at Debug,
  queries + HTTP calls at Verbose, notices by severity. Console report stays
  separate.
- Core (additive, inert when unused): NpgsqlRestOptions.AmbientConnectionAccessor
  + connection-selection branch; RoutineInvokeResult.Headers; endpoint
  notice-handler leak fix (named delegate detached in finally);
  NpgsqlRestLogger.LogConnectionNotice ILogger overload.
- 33 parser unit tests (NpgsqlRestTests/TestRunnerTests/ParserTests/).

Shippable in 3.19.0 (changelog/v3.19.0.md):
- SqlFileSource.SkipPattern (default *.test.sql) — exclude files from endpoint
  discovery; included iff matches FilePattern AND not SkipPattern.
- Log:MinimalLevels accepts "Off"/"None"/"Silent" to fully mute a logger
  (minimum level above Fatal); null/omitted still falls back to the default.

Config synced across appsettings.json, ConfigTemplate.cs, ConfigDefaults.cs,
ConfigSchemaGenerator.cs. Full suite green (2334) + 33 parser + 94 config tests.

…angelog

Test database / separate test connection:
- TestRunner.ConnectionName: run tests (endpoint Describe + execution) against
  a named ConnectionStrings entry instead of the app's main connection; not
  opened/validated at startup, so a Setup step can create the database first.
- Per-step ConnectionName on Setup/Teardown Sql/SqlFile steps (e.g. an Admin
  maintenance connection running `create database`); runner issues no DDL of
  its own. Steps now run in the exact order written (dropped Command-first
  grouping). BuildTestRunnerConnectionStrings resolves entries unvalidated.
- {rnd1}..{rnd10} config placeholders: random lowercase tokens (length =
  digit), generated once per run, substituted everywhere {ENV} works — one
  stable name across connection string, create, and drop.

Hardening round (full-feature review):
- `# @expect-status` removed — assert on the response temp table's status
  column instead; HTTP blocks are pure act steps.
- Code generation (HTTP files, TS client, OpenAPI) skipped in --test mode —
  a test run never rewrites generated artifacts.
- login/logout endpoints rejected in test mode with a clear error (inject
  the principal with `# @claim` instead).
- Request matching no endpoint logs a warning (path typo / missing /api
  prefix) — the 404 remains assertable.
- Per-step exception attribution: errors thrown by HTTP steps (e.g. 42P07
  duplicate `# @response` table) report with the block's file:line.

Rename: TestRunner.Verbose -> DetailedReport (detailed console report:
passed ✓ lines, full failing SQL, notices for passing tests) — removes the
collision with the Serilog "Verbose" level in Log:MinimalLevels.

changelog/v3.19.0.md rewritten: SQL test runner documented as the headline
feature with a full user manual (execution model, file anatomy, HTTP-block
syntax, response temp tables, Setup/Teardown, test-database workflow,
reporting, logging, config reference), plus SqlFileSource.SkipPattern and
MinimalLevels "Off".

Config synced across appsettings.json, ConfigTemplate.cs, ConfigDefaults.cs,
ConfigSchemaGenerator.cs. Full suite green (2334); examples 19 + 20 verified
end-to-end (fresh {rnd}-named test DB created, migrated, tested, dropped).

…own/connection

Script reuse — \i / \ir includes (psql syntax, paste semantics):
- `\i path` (cwd-relative) / `\ir path` (relative to the including file) on
  its own line splices the included file's content in place, as if pasted:
  SQL statements, assertions (attributed to the included file), HTTP blocks
  (participate in _response_{n} numbering), and header annotations (a shared
  annotation "profile" attaches with one include line).
- Recognized only between statements (never inside strings/dollar-quotes;
  no statement fragments — use functions/views). Nested, cycle-safe,
  depth-capped. Works in Setup/Teardown SqlFile steps. Errors report the
  included file's name and line. Quoted paths and a trailing ';' accepted;
  other backslash lines pass through to PostgreSQL untouched.

Named steps (TestRunner.Steps):
- name -> step dictionary (same idiom as ConnectionStrings/Profiles);
  Setup/Teardown arrays mix name references and inline step objects;
  unknown name is a configuration error (exit 3). Step logs show
  phase + name + resolved code: `setup step CreateTemplate: create
  database app_template_abc`.

Per-file header annotations (leading -- comments, before the first statement):
- `-- @setup Name [Name ...]`  runs named steps before the file
- `-- @teardown Name [Name ...]` runs after the file — always, best-effort,
  after the file's connection closes (so `drop database ... with (force)`
  works), on the run token (survives per-test timeout)
- `-- @connection Name` runs the file, including its in-process endpoint
  calls, on a named ConnectionStrings entry
- Repeatable; names whitespace- or comma-separated; accumulate and execute
  in written order (teardown not reversed); setup fail-fast, teardown
  best-effort. Together these enable per-test database isolation: clone a
  template, run in the clone, drop it (deterministic sequence ids).

{rnd} indexed instances:
- {rndN_1}..{rndN_9} are independent random tokens per length (all stable
  per run) for when several distinct same-length names are needed.

Changelog updated (paste-model includes, named steps, per-file annotations,
indexed tokens, example 21). Config synced across appsettings.json,
ConfigTemplate.cs, ConfigDefaults.cs, ConfigSchemaGenerator.cs. Full suite
green (2351) incl. 50 parser tests; examples 19/20/21 verified end-to-end
(21: two parallel per-test clones from one template, shared annotation
profile via \ir, Command step with {rnd} substitution).

…ase 3)

Test filtering (TestRunner.Filter):
- Narrow the discovered set: a value without wildcards is a case-insensitive
  substring match against the cwd-relative path (--testrunner:filter=login);
  with wildcards it uses the same glob engine as FilePattern. Setup/Teardown
  still run; zero matches exits 4 (AllowEmpty applies).

Watch mode (--watch / TestRunner.Watch, interactive/dev-only):
- Setup once, run once, then watch the FilePattern base directory recursively
  for *.sql changes (debounced): a changed test file re-runs alone (Filter
  applies); any other changed .sql (an included fixture/profile) re-runs
  everything. Endpoint sources are not watched — restart to rebuild.
- Teardown runs ONCE, on exit: SIGINT and SIGTERM are intercepted via
  PosixSignalRegistration (Console.CancelKeyPress proved unreliable headless;
  plain SIGTERM previously killed the process without teardown, leaking the
  test database). Graceful stop exits 0 — not for CI gating.
- Extracted ExecuteDiscoveredFilesAsync (run core without teardown); RunAsync
  keeps teardown-in-finally for CI mode.

Tags (-- @tag name [name ...] header annotation):
- TestRunner.Tag runs only files carrying at least one listed tag;
  TestRunner.ExcludeTag skips files carrying any (exclude wins). CSV or
  whitespace-separated, case-insensitive, composes with Filter. Tags travel
  through profile includes (as-if-pasted), so e.g. every clone-isolated test
  is automatically tagged slow by its profile.

Endpoint coverage (TestRunner.Coverage / CoverageThreshold):
- After the run: exercised N of M testable endpoints + the list of untested
  ones (kinds the runner rejects — SSE, upload, login/logout, outbound proxy —
  are excluded from the ratio and counted separately). CoverageThreshold
  (0-100, implies Coverage) fails an otherwise-passing run with exit 2 —
  CI gating for "every endpoint has a test". Covered = invoked at least once.

Config synced across appsettings.json, ConfigTemplate.cs, ConfigDefaults.cs,
ConfigSchemaGenerator.cs; --watch whitelisted; --help updated. Changelog
v3.19.0.md updated with all four features. Full suite green (2364) incl. 63
runner unit tests; examples 19/20/21 verified end-to-end (filter modes, watch
rerun-on-change + signal teardown, tag taxonomies incl. profile-carried tags,
coverage report + failing threshold gate).

…med report

Watch mode — endpoint source tree (SqlFileSource):
- When the SQL file source is enabled, watch mode also watches its tree: a
  changed endpoint file triggers an in-process endpoint rebuild (UseNpgsqlRest
  re-reads + re-describes against the test database and atomically swaps the
  endpoint registry; a failed rebuild keeps the previous endpoints) followed
  by a full rerun. The endpoint delta is reported after each rebuild
  (+ METHOD path / - METHOD path "endpoint dropped - check its SQL file"), so
  breaking an endpoint mid-session is visible immediately and fixing it
  recovers - no restart. Watch mode forces SqlFileSource.ErrorMode from Exit
  to Skip (a broken file must not kill the session); non-watch --test keeps
  Exit for CI.

Guaranteed teardown (fixes two database-leak classes):
- From Setup onward, SIGINT (Ctrl+C) and SIGTERM are intercepted and Teardown
  runs SYNCHRONOUSLY in the signal handler - wrappers like `bun run` forward
  Ctrl+C to the process group and kill their children immediately, so the old
  cooperative unwind lost the race and leaked the test database. A second
  signal force-quits. Non-watch --test previously had no handler at all.
- An AppDomain.ProcessExit hook covers hard exits: SqlFileSource
  ErrorMode=Exit's Environment.Exit(1) previously leaked the just-created
  test database; exit code unchanged, Teardown now runs first.
- All paths funnel into a run-once teardown that hands every caller the SAME
  task (a fire-once no-op guard let the process exit mid-DROP).
- An interrupted non-watch run exits 2.

Console report themed to Serilog's Code theme:
- FAIL/ERROR labels render as the byte-identical chip the Code theme uses for
  its ERR/FTL level (red-197 on grey-238); PASS uses the same chip grammar in
  the mirror green-47; line text stays in the terminal's normal color; ALL
  failure text unified on the theme's red-197 foreground (two stragglers used
  16-color ConsoleColor.Red, which renders orange in some themes).
  Out.LineChip renders chips, plain when redirected.

Changelog updated (endpoint watching, teardown guarantees, report theming,
exit codes). Full suite green (2364); verified live: benign endpoint edit ->
rebuild + green, broken endpoint -> dropped-endpoint delta + failing tests,
fix -> recovery; broken-endpoint hard exit -> exit 1 with ZERO leaked
databases; watch SIGTERM -> full teardown, zero leftovers.

AnsiFail is now the full Serilog Code ERR chip style (red-197 on grey-238)
and is the ONLY red in the report — FAIL/ERROR labels and every failure line
(assertion details, messages, failing summary, coverage gate, setup/config
errors) share the exact same escape sequence, so they can never render
differently. AnsiOk is the mirror (green-47 on grey-238) for the PASS label
and the all-green summary. Indentation and blank lines are written outside
the styled block so the grey strip starts at the text.

…-state)

TestRunner.Coverage is now tri-state:
- null (the new default): report the endpoint-coverage summary after FULL
  runs — it costs one line and surfaces untested endpoints passively — but
  stay quiet when the run is narrowed by Filter/Tag (a deliberately partial
  run would just nag about endpoints its subset never touches);
- true: always report, including narrowed runs;
- false: never report.
CoverageThreshold always reports and gates when set, regardless of Coverage
or narrowing — it is an explicit ask for enforcement.

Config synced (appsettings.json, ConfigTemplate.cs, ConfigDefaults.cs,
ConfigSchemaGenerator.cs — incl. previously missing schema descriptions for
Coverage/CoverageThreshold). Changelog updated. Full suite green (2364);
all five behaviors verified live (default-on full run, narrowed suppression,
forced on, forced off, threshold reporting).

SQL file endpoints can use named placeholders instead of positional $1..$N:

    select * from users where email = :email and age > :age;

The placeholder IS the parameter: :email becomes API parameter "email"
through the same NameConverter routine parameters use (:user_id -> userId),
so @param annotations that existed only to NAME positional parameters become
unnecessary. Claim mappings (ParameterNameClaimsMapping, @user_parameters)
hook up by the placeholder's own name with zero annotations.

Mechanics: statements are rewritten to native $N right after parsing —
PostgreSQL never sees :name, so Describe, type inference, and runtime
behavior are identical to positional files. The same name (case-insensitive,
first spelling wins) maps to ONE parameter file-wide, including across
statements in multi-command files. Token-aware rewriter: strings ('', ""),
comments (nested /* */), and dollar-quoted bodies untouched; :: casts, :=
calls, and numeric slice bounds (a[1:3]) never match (variable slice bounds
need a space: a[1 : n]). Mixing $N and :name in one file is rejected
(ErrorMode semantics).

Annotations match named parameters by name: `@param email default null`
works as-is; `@param :email citext` is a Describe type hint; the new
`@param email type is citext` form retypes WITHOUT rename (core
ParameterHandler, delegates to the rename path as rename-to-same-name;
also tolerates a leading ':' on the parameter reference). Typed-annotation
detection for HTTP-client/composite types accepts the named form.

`?` (JDBC style) considered and rejected: ?, ?|, ?& and @? are PostgreSQL's
own jsonb/geometric operators — no rewriter can safely claim `?`; same
reason the PG JDBC driver requires ?? escapes. Documented in the changelog.

Tests: 22 rewriter unit tests + 7 end-to-end endpoint tests (auto-naming,
repeated placeholder from one value, required-param matching, name-matched
defaults, `type is` retype producing an unquoted JSON int, claim mapping by
placeholder name, mixed-style rejection, multi-command cross-statement
sharing). Full suite green (2393). Example 20's login.sql converted to
:email/:password live (docs repo, committed separately). Changelog section
+ plugin README updated.

…onfig changes

--watch is now a two-mode flag: with --test it is the test runner's in-process
watch (unchanged); WITHOUT --test it runs the SERVER under a watch supervisor.

Supervisor/child design (same model as dotnet watch): the process spawns
itself as a child server (marked via NPGSQLREST_WATCH_CHILD; value = the
supervisor PID) and watches the SqlFileSource tree plus the configuration
files. On a debounced change it stops the child gracefully and starts a fresh
one — the child runs the completely normal server pipeline (discovery,
describe, code generation, Kestrel), so dev is production behavior. The one
relaxation: SqlFileSource ErrorMode is forced Exit->Skip in the watch child so
a broken SQL file logs its error and drops only its own endpoint.

Details:
- Edits to files matching SqlFileSource.SkipPattern (test files) do NOT
  restart the server.
- Child crash: the supervisor prints "server exited (code N) — waiting for
  file changes" and revives on the next relevant save (no crash-looping).
- Graceful stop: SIGTERM via libc DllImport on Unix (Process.Kill is SIGKILL);
  hard process-tree kill on Windows (a dev server has no teardown needs).
- Parent watchdog in the child: if the supervisor dies without stopping it
  (SIGKILL, wrapper runners like bun run), the child exits by itself — no
  orphan holding the port.
- Spawn works from the AOT binary (Environment.ProcessPath) and under
  `dotnet NpgsqlRestClient.dll` (dotnet host re-invoked with the dll).
- DOTNET_USE_POLLING_FILE_WATCHER=1 switches to a 1s polling scan for
  environments where file events don't cross the filesystem boundary
  (Docker Desktop bind mounts).
- --watch without --test and without an enabled SqlFileSource exits with a
  clear error (nothing to watch).
- WatchUtils extracts the shared watch primitives (base dir, debounce,
  pattern match); the test runner delegates to it, behavior identical.

Plan B (in-process endpoint hot-swap via a dynamic EndpointDataSource,
target 3.20) is designed in scrap/WATCH_HOT_SWAP_PLAN.md.

Verified live across 12 scenarios: initial serve, add/break/fix endpoint
file (broken file 404s while the rest keeps serving), test-file edit ignored,
config-edit restart, child crash recovery, supervisor SIGKILL -> child
self-exit (no orphans), SIGTERM graceful stop with port freed, polling mode,
nothing-to-watch error, and test mode unaffected. Full suite green (2393).
Changelog: watch documented as a single two-mode feature.

…both flavors

Watch mode now watches ALL endpoint sources in BOTH flavors. Routine-source
endpoints (functions/procedures) have no files to watch, so watch mode polls
the DATABASE — with perfect fidelity: RoutineSource.CreateFingerprintCommand
runs the SAME discovery query the endpoint source uses (same Query property,
same ten configured filter parameters — refactored into a shared command
builder used by Read() too), wrapped in an order-independent server-side hash
(select sum(hashtextextended(q::text,0)) from (<query>) q). If the hash
changes, the discovered endpoints changed — by definition: create/replace/
drop/alter of functions and procedures (function bodies are in the result via
pg_get_functiondef), GRANT/REVOKE, COMMENT ON (annotations), and changes to
the composite types and tables used as parameter/return types. Anything the
discovery query does not read — unrelated tables, temp objects, data — can
never cause a spurious trigger.

- WatchDbPoller (client): polls on a dedicated non-pooled connection, takes
  the actual configured RoutineSource instances from EndpointSources; skips
  cleanly when there are none. Rebaseline() prevents self-triggering.
- Server watch: the child polls and exits with code 64 -> the supervisor
  respawns immediately ("database change detected — restarting"). Supervisor
  loop reworked so the pending change batch survives respawn iterations (no
  competing channel readers). Routines-only projects are now watchable:
  --watch is valid without a SQL file source when polling is active.
- Test watch: the poller feeds a sentinel into the existing change channel ->
  endpoint rebuild + full rerun ("change detected (database)"); the runner
  re-baselines after every rerun so committed fixtures never re-trigger.

Config consolidated into ONE top-level Watch section (TestRunner.Watch
REMOVED — it was the same word with a different type and role):

    "Watch": { "Enabled": false, "DatabasePollingInterval": "2s" }

--watch is the CLI shorthand for Watch:Enabled (--watch:enabled=true also
works); the flavor is picked by --test. Polling accepts "2s"/"500ms"/"1m"/
seconds/hh:mm:ss, 0 disables, and deactivates automatically when
RoutineOptions.Enabled is false. Config synced x4 + schema descriptions.

Tests: WatchDbFingerprintTests proves the hash tracks the discovery result
exactly (create/replace/comment/drop and used-type changes fire; temp objects
and unrelated tables never do; nameSimilarTo filter wiring verified). Full
suite green (2394). Live-verified: function created in psql serving ~2s
later on a routines-only watch; replace -> new body; drop -> 404; alter table
add column reshaping a `returns setof` endpoint ([{"id":1}] ->
[{"id":1,"name":"ada"}]); unrelated table create/drop -> zero restarts;
test-watch database rerun without loops; all four activation paths
(server/test x flag/config). Changelog: watch section finalized.

…debug mirror

Captured responses live in per-connection temp tables that vanish with the
test's rollback and connection close — impossible to examine in a query
editor afterwards, and re-issuing the request from an .http file cannot
reproduce a response that depended on the test's uncommitted transactional
fixtures.

New setting ResponseTempTable.DebugTable (default null = off): when set
(e.g. "_responses_debug"), every captured response is ALSO mirrored into a
PERMANENT table with that name, written on a separate autocommit pooled
connection — immune to rollbacks and connection closes, append-only so
parallel test files cannot collide. The temp-table semantics (assertions,
naming, transactions) are completely unchanged.

ONE table covers the whole run: each HTTP block adds one row with
captured_at, test_file, block (that block's response-table name — Name, a
MultiNamePattern ordinal, or the # @response name), method, path, status,
body, content_type, headers, is_success. Recreated at the start of every
run, so it always holds the LAST run. Enabling it prints a loud warning
(debugging aid — do not enable in CI); mirror inserts are best-effort (a
failure logs a warning, never fails the test). In the fresh-test-database
workflow combine with Keep, or teardown drops the database and mirror.

Note: the naive alternative ("Permanent": true on the response table) was
rejected — parallel tests would collide on one permanent name, and CREATE
TABLE is transactional, so the rollback would erase the table exactly when
it was needed.

Config synced (appsettings.json, ConfigTemplate.cs, ConfigDefaults.cs,
ConfigSchemaGenerator.cs). Full suite green (2394). Live-verified on
example 19: all three block-naming schemes distinguishable in one query,
including the response body of a rolled-back fixture; rerun leaves exactly
the last run's rows. Changelog + docs updated.

…in appsettings.json

The DebugTable comment block was removed from appsettings.json (leaving a
stray whitespace-only line) but ConfigTemplate.cs still carried it, so the
Config_OutputMatchesAppsettingsJson byte-match test failed on CI.
appsettings.json is the source of truth: the stray line is removed and the
template now matches it exactly. The setting stays documented in the JSON
schema description, the changelog, and the docs site.

…s" interval support

Every Setup/Teardown step now has an "Enabled" flag (default true). A
disabled step is simply IGNORED wherever it is referenced — Setup/Teardown
arrays or per-file -- @setup / -- @teardown annotations — skipped with a
debug log line, never an error. Referencing an UNKNOWN name remains a loud
configuration error; Enabled=false is the one sanctioned skip.

The default configuration ships six DISABLED example steps in
TestRunner:Steps showing every step property (Sql, SqlFile, Command,
WorkingDirectory, ConnectionName, Enabled) across the typical scenarios:
CreateTestDatabase / DropTestDatabase ({rnd5}-named database on an "Admin"
connection), ApplySchema (SqlFile), RunMigrationTool (Command +
WorkingDirectory), StartDockerPostgres / StopDockerPostgres. Instead of
typing a step from scratch, copy one, adjust names/paths/connections, and
flip Enabled to true. (Defaults are a copy-from reference visible in
appsettings.json and --config output — not a runtime layer merged into
explicit config files.)

Also from the config-comment review:
- ParseTestTimeout gained "ms" support ("500ms") — the Watch comments and
  changelog already promised it but the parser silently fell back to the
  default (verified: --watch:databasepollinginterval=500ms -> poll 0.5s).
- ResponseTempTable section comment carries a compact one-line DebugTable
  description; FilePattern comment names both test layouts.

Config synced x4 + schema (byte-match green). Full suite green (2394).
Live-verified: disabled-referenced step skipped with debug line + run green;
flipped on via CLI override -> step executes; custom user step names produce
no validation warnings (example 20 clean). Changelog + docs updated.
