🛠️ Description of Changes

The Tenant facility endpoints now resolve their state-changing operations through an interface the DMRP module replaces with its own implementation when DMRP:Enabled is set, so a facility's scheduled reports are derived from its DMRP reporting plans instead of being chosen by the caller.

No BFF changes, and no new routes. The ADR's BFF Reverse Proxy and Shared Interface section was written when DMRP was expected to be a separately deployed service. It is a class library hosted in-process by Tenant, and api/dmrp/** already proxies to the Tenant cluster, so the reverse-proxy hop it describes has no counterpart in the code. The facility URL surface is identical with the flag on or off; only the behavior behind POST, PUT and DELETE differs.

Backend

  • IFacilityOperations (DMRP) declares the five state-changing facility operations; TenantFacilityOperations (Tenant) is the host's implementation, holding the manager call and the ScheduleService reconciliation lifted out of the controller.
  • DmrpFacilityOperations wraps it when the flag is on: create and update refuse a caller-supplied scheduledReports and derive one from the facility's reporting plans; hard delete removes the facility first and its plans second; soft delete and restore pass through.
  • DbBackedReportingPlanSource reads FacilityReportingPlans joined to MeasureMappings for the period the facility is currently in, read in its own timezone. IReportingPlanSource is the seam the DMRP API client slots into with LEGLINK-698/701.
  • AddDmrpModule gains a type parameter naming the host's implementation, so a host that supplies none fails to compile rather than at startup.
  • FacilityController calls the interface; its validation, sanitization and status codes are unchanged.

Admin UI

  • The facility form required at least one scheduled report, which the API now refuses — no input satisfied both, making facility create and edit impossible with DMRP on. ScheduledReportsValidator takes the flag and drops that rule; the report pickers are replaced by a line saying the schedule is derived; submit sends empty arrays.

Two defects fixed in the measure mappings endpoints

Both were found while documenting these endpoints, and predate this work:

  • Deleting a measure mapping that reporting plans still reference answered 404. The row plainly exists and is readable, so reporting it missing said the opposite of what happened. It now answers 409 with a message naming the reason, checked before the delete is attempted so a refusal changes nothing. Delete-all is refused the same way while any plan exists. A mapping that genuinely does not exist still answers 404.
  • DELETE /api/dmrp/measure-mappings/{id} was the only write endpoint on the controller without [ValidateAntiForgeryOrBearerToken].

Configuration

  • DMRP:Enabled moves from the Tenant section of app-config.yaml to global. It is one decision for the deployment, and unlabeled means every service reads the same answer. The Angular app cannot read App Configuration, so the same decision reaches it via LINK_DMRP_ENABLED on its container. The two must agree — the UI switched on ahead of the services quietly creates facilities that report nothing, while the reverse fails loudly.
  • No migration (no entity changes) and no new config key. DMRP:Enabled is absent from every environment store and defaults to false, so DMRP is currently off everywhere.

Deviations from the ADR, for QA

  1. No BFF changes and no api/dmrp/facility/** routes, as above.
  2. scheduledReports must be sent as empty arrays, not omitted — its arrays are non-nullable, so an absent block fails model binding before the API sees it.
  3. Reporting plans are read from the table, not fetched from the DMRP API. That arrives with LEGLINK-698/701, so until then a facility gets an empty schedule unless its plan rows are seeded first.

🧪 Testing Performed

Full .NET suite green: 2280 passed, 1 skipped, 0 failed. link-cloud.sln builds with 0 errors. ng build clean; validate_app_config_schema.py passes and check_required_config.py reports every required key present in dev, qa and test.

End-to-end against the local docker-compose stack, Tenant with DMRP:Enabled=true, seeding two measure mappings (HOB to monthly, HTCDI to daily) and reporting plans for the current period:

Step Result
Module loads with the flag on DMRP module enabled: True
POST /api/Facility with scheduledReports 400 naming DMRP as the source
POST /api/Facility with empty scheduledReports 201, daily = RPS dQM, monthly = ACH dQM, weekly empty
PUT with a caller-supplied schedule 400
PUT with empty schedule 200, schedule re-derived
softDelete then re-query plans 2 rows kept
restore then re-query plans 2 rows kept
hard DELETE then re-query plans 0 rows; log confirms Deleted 2 reporting plan(s)
Flag off: api/dmrp/** 404
Flag off: caller's scheduledReports 201, honored verbatim
Flag off: full facility lifecycle all 204

That run found and fixed a real defect: the refusal message originally said "resubmit without scheduledReports", which model binding makes impossible. It now names the empty-arrays remedy, verified end to end.

The measure mappings delete fix was verified the same way:

Request Result
DELETE /{id} on a referenced mapping 409 and "referenced by one or more facility reporting plans"
GET /{id} afterwards 200 — the refusal changed nothing
DELETE all while a plan exists 409
DELETE /{id} after clearing the plan 204, then 404 on re-read
DELETE /{id} on a mapping that never existed 404 — still distinct

Measure-definition validation was disabled for the facility run (MeasureConfig__CheckIfMeasureExists=false) via an override file outside the repo, so docker-compose.yml carries no test-only change. Not yet covered: a seeded full-stack run confirming realistic dQM mappings produce a facility Tenant accepts with that validation on.

🧑‍🔬 Unit Testing

  • I have written or updated unit tests to cover my changes
  • Coverage: 57.5%
    • DmrpFacilityOperationsTests — schedule derivation, distinct dQMs when two measures map to one, unmapped measures excluded, reporting period read in the facility's timezone with a UTC fallback for an unusable one, refusal on create and update, an explicitly empty block accepted, delete ordering (facility first, plans second) and plans kept when the inner delete throws.
    • DbBackedReportingPlanSourceTests — SQLite-backed filtering by facility and period, IsReporting=false excluded, unmapped measure returned with no dQM.
    • DmrpModuleExtensionsTests — the module fronts the host's operations when enabled and leaves them alone when disabled.
    • DmrpFacilityOperationsIntegrationTests — the wiring end to end: the module really does front the host, and the schedule comes from rows read out of the database.
    • MeasureMappingsControllerTests — delete refused with 409 while a reporting plan references the mapping (and the mapping still readable afterwards), 204 when nothing references it, 404 when it does not exist.
    • FacilityControllerTests.Facility_lifecycle_keeps_the_scheduled_jobs_in_step — asserts Quartz job presence across create, soft delete, restore and delete. Added because the existing controller tests assert status codes only, and job re-creation was dropped from restore during this work without any test noticing.
    • ScheduledReportsValidator.spec.ts — 5 specs covering both flag states and the parameter default.

📓 Documentation Updated

  • XML documentation on all 15 DMRP controller endpoints (params, response codes, validation rules), which Swagger picks up through the DMRP XML file Tenant already feeds it. The same text is on the matching requests in the Link Admin BFF Postman collection, including the new 409 behavior.
  • app-config.yamlDMRP:Enabled re-catalogued as a global system switch, with the UI/services agreement requirement and its asymmetric failure modes recorded.
  • The DMRP UI flag is temporary and expected to end up permanently on, so it is written to be deleted: every site is marked DMRP feature flag and the removal recipe lives on AppConfig.dmrpEnabled.

Summary by CodeRabbit

  • New Features
    • Added DMRP-based facility scheduling, deriving daily, weekly, and monthly reports from reporting plans.
    • Added a system-wide DMRP feature switch for enabling or disabling plan-driven scheduling.
    • Facility creation, updates, deletion, soft deletion, and restoration now keep schedules and reporting plans synchronized.
  • Bug Fixes
    • Prevented deletion of measure mappings still referenced by reporting plans, returning a conflict response.
    • Unmapped measures are excluded from generated schedules.
  • UI
    • Facility configuration now explains when schedules are controlled by reporting plans and adjusts validation accordingly.
  • Documentation
    • Expanded endpoint documentation and error-response details.

The Tenant facility endpoints now resolve their state-changing operations through
IFacilityOperations, which the DMRP module replaces with its own implementation
when DMRP:Enabled is set. Routes and the BFF reverse proxy are unchanged - only
the behavior behind POST, PUT and DELETE differs.

With DMRP enabled:

- Create and update refuse a caller-supplied scheduledReports block and derive
  the schedule from the facility's reporting plans instead, grouping the mapped
  dQMs by the frequency their measure mapping carries. A measure with no dQM
  mapped is logged and excluded rather than silently dropped.
- Hard delete removes the facility first, then its reporting plans, so plans
  survive a delete the host refuses. Soft delete keeps them, since the facility
  can be restored.
- The reporting period is read in the facility's own timezone, so a facility near
  a month boundary is scheduled against the month it is actually in.

Plans are read from the FacilityReportingPlans table behind IReportingPlanSource.
An implementation that refreshes those rows from the DMRP API takes its place with
LEGLINK-698/701, and nothing consuming the interface changes.

The module takes over the IFacilityOperations registration and delegates to the
host's implementation, which it names through a type parameter, so a host that
does not supply one fails to compile rather than at startup.

Also adds a facility lifecycle test asserting Quartz job presence across create,
soft delete, restore and delete. The existing controller tests assert status codes
only, so scheduling could be dropped from any of those paths unnoticed.
End-to-end testing showed the refusal named something the caller cannot do.
TenantScheduledReportConfig's Daily, Weekly and Monthly are non-nullable, so a
request that leaves scheduledReports out is rejected during model binding with
"The Daily field is required" before the DMRP module runs. Telling the caller to
resubmit without the block sent them to a different 400 with no way forward.

An empty block is what gets through, so the message asks for that instead.

Adds tests pinning both halves of the contract: an explicitly empty block is
accepted rather than treated as a caller-supplied schedule, and the refusal names
the empty-array remedy. Neither is reachable from a unit test of the operations
alone - the binding failure sits above where they call in - so the message could
drift back without the second one.
Both DMRP controllers carried a one-line summary per action and nothing else, so
the parameter ranges, the validation rules and the meaning of each status code
lived only in the code. All fifteen endpoints now carry param and response
documentation, which Swagger picks up through the DMRP XML file the Tenant
service already feeds it. The same text is on the matching requests in the Link
Admin BFF Postman collection.

Behavior that was previously undocumented and is easy to get wrong:

- Reporting plans refuse out-of-range paging rather than clamping it, while
  measure mappings quietly replace it with the default. The two controllers
  disagree, so both now say which they do.
- An empty measure mapping search answers 204, while an empty reporting plan
  search answers 200 with an empty page.
- A measure mapping created without a frequency defaults to Adhoc, which
  schedules nothing.
- Deleting a measure mapping that reporting plans still reference answers 404
  rather than a conflict, because the manager reports a refused delete and a
  missing row as the same failure. Distinguishable only by the message.

Also drops the 404 ProducesResponseType from DeleteAllMeasureMappings, which has
no path that returns one.
With DMRP enabled the Tenant API derives a facility's scheduled reports from its
DMRP reporting plans and refuses a request that supplies its own. The facility
form did the opposite: ScheduledReportsValidator required at least one report, so
no input satisfied both and facility create and edit were impossible. The local
docker stack has been in that state since DMRP__Enabled was set true there; no
deployed environment is affected, because DMRP:Enabled is absent from every store
and defaults to false.

The form now asks the flag what to do:

- ScheduledReportsValidator takes it and drops the "at least one report" rule when
  DMRP is on. Duplicates are still rejected either way.
- The report pickers are replaced by a line saying the schedule is derived.
- Submit sends empty arrays. Editing an existing facility loads its stored
  schedule into the controls, so they are emptied explicitly rather than assumed
  untouched. The block itself is still sent: its arrays are not nullable, so
  omitting it fails model binding before the API sees it.

DMRP:Enabled moves from the Tenant service section of the config catalog to
global. It is one decision for the deployment rather than one service's setting,
and unlabeled means every service reads the same answer. The Angular app cannot
read App Configuration, so the same decision reaches it through the container's
LINK_DMRP_ENABLED. The two must agree, and the failure modes are not symmetric:
the UI switched on ahead of the services quietly creates facilities that report
nothing, while the reverse fails loudly. The catalog and the code both say so.

The flag is temporary and expected to end up permanently on, so it is written to
be deleted: every site is marked "DMRP feature flag", the removal recipe is on
AppConfig.dmrpEnabled, and the validator parameter defaults to the state the flag
settles on, with a test pinning that.
… a not-found

Deleting a measure mapping that facility reporting plans still reference answered
404. The row plainly exists and is readable, so reporting it as missing tells the
caller the opposite of what happened. The manager wrapped every save failure in
ApplicationException, which the controller could only map one way.

The mapping is now asked about before it is deleted: if any reporting plan
references it, the request is refused with 409 and a message naming the reason.
Delete-all is refused the same way while any plan exists, checked before anything
is removed so a refusal deletes nothing rather than part of the table. A mapping
that genuinely does not exist still answers 404.

The check is a query rather than a translated database error because the error is
not stable enough to classify on. Which one the database raises depends on EF's
change tracker: with the dependent untracked the DELETE reaches the database and
the foreign key fires (SQL Server 547, SQLite 787), but with it tracked EF first
tries to sever the relationship by nulling MeasureMappingId, which the NOT NULL
column rejects instead (SQL Server 515, SQLite 1299). Classifying on the code
alone would have behaved differently in a controller request than in a test. The
translation is kept as a backstop for the window between the check and the delete,
now covering all four codes.

Also adds ValidateAntiForgeryOrBearerToken to DeleteMeasureMapping, which was the
only write endpoint on the controller without it.

Both defects were found while documenting these endpoints and were called out then
as belonging to the measure mappings work rather than the DMRP facility
integration.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to e8177

When DMRP is enabled, facility mutations now derive schedules from reporting plans and measure-mapping deletion returns a conflict while plans reference a mapping. The current head is mergeable with owner awareness because invalid facility IDs can still reach delete logic without a guard, bulk deletion is not available through the SDK, and DMRP activation relies on registration order; these are bounded follow-ups rather than demonstrated release-blocking failures.

Log arguments in the two new DMRP files called Sanitize(), the HTML sanitizer.
It strips markup but leaves CR/LF, so a facilityId or measure containing a
newline could still forge log lines. Both values come from request bodies. They
now call SanitizeForLog(), which replaces control characters, matching every
sibling in the module. Five call sites across DbBackedReportingPlanSource and
DmrpFacilityOperations.

The DeleteAllAsync pre-check added earlier refuses while any reporting plan
exists, which turned a leaked row into an unrelated failing test: the three DMRP
integration classes share one SQLite file, run in an unspecified order, and
cleared plans in their constructor only. Cleanup now also runs in Dispose, so a
class cannot leak rows into whichever runs next.

Adds the two tests the new branches were missing:

- DeleteAllMeasureMappings refused with 409 while a reporting plan exists, also
  asserting an unreferenced mapping survives the refusal.
- The facility form with DMRP enabled, covering the case the conditional exists
  for: editing a facility loads its stored schedule into the report controls, so
  submitting an otherwise untouched facility has to send empty arrays rather than
  hand the stored schedule back to an API that refuses it.

Turns DMRP off in the docker stack. FacilitySetupHelper creates facilities with a
schedule of its own, which the refusal rejects, so enabling DMRP there broke the
Backend E2E suite. DMRP:Enabled in appsettings.Docker.json and LINK_DMRP_ENABLED
in docker-compose move to false together - the UI switched on ahead of the
services is the silent failure mode, so they are never flipped separately. The
compose comment records what to set to exercise DMRP locally.
…tion

Hard delete removed the facility, then its reporting plans, with nothing tying
the two together. A failure after the facility row was gone stranded the plans:
nothing ever collected them, they blocked measure mapping deletes, and a facility
later created with the same id silently inherited a previous incarnation's
schedule.

Both persist through the host's database context - the facility repository and
the reporting plan repository resolve the same scoped instance - so one
transaction covers them. The order is unchanged, since the host's delete can
still refuse and plans removed ahead of a refused delete would leave a facility
that reports nothing.

Quartz keeps its own store and cannot enlist, so a rollback leaves the restored
facility without its scheduled jobs. That was the argument against a transaction
here, and it does not hold: ScheduleService.StartAsync rebuilds jobs for every
facility that is not deleted, and DeleteJobsForFacility is idempotent, so the
gap closes on the next restart or delete retry. A stranded reporting plan closes
on nothing.

The rollback is guarded. If it fails it is logged with the facility and the
endpoint that clears its plans, and the original exception is rethrown - the
caller needs to hear about the delete that failed, not the cleanup that failed
afterwards.

Tests cover the transaction protocol in order, rollback without commit when the
plan cleanup throws, and the original exception surviving a failing rollback.

Consider moving IFacilityOperations out of the DMRP assembly.

The Tenant controller and Program.cs now import LantanaGroup.Link.DMRP.Business to resolve the seam that the host itself owns. The dependency direction points from the host to the optional module. Moving IFacilityOperations and ScheduledReportsNotAcceptedException into the shared assembly would let DMRP depend on Tenant contracts instead of the reverse. This is a structural preference, not a defect, so treat it as optional.

Make the registration order requirement explicit.

RemoveAll<IFacilityOperations>() only works if the host registered IFacilityOperations before it called AddDmrpModule. If a future edit moves AddDmrpModule above the host registration in Program.cs, RemoveAll becomes a no-op and the host's later AddScoped<IFacilityOperations, TenantFacilityOperations> wins. DMRP would then be enabled with none of its facility behavior active, and no error would report it.

Two options remove the hazard.

  1. Register the host implementation for IFacilityOperations inside this method, since THostFacilityOperations is already known. The host then does not register the interface at all.
  2. Keep RemoveAll, but assert that at least one IFacilityOperations descriptor existed before removal, and throw otherwise.

Option 1 also removes the duplicate registration in Program.cs line 157.

♻️ Proposed guard for option 2
-            builder.Services.RemoveAll<IFacilityOperations>();
+            if (builder.Services.RemoveAll<IFacilityOperations>() is var services
+                && !services.Any(d => d.ServiceType == typeof(IFacilityOperations)))

+
+            // Fail loudly rather than silently leaving the host implementation in front.
             builder.Services.TryAddScoped<THostFacilityOperations>();

A simpler form is to capture the count before the call:

var hadHostRegistration = builder.Services.Any(d => d.ServiceType == typeof(IFacilityOperations));

if (!hadHostRegistration)
{
    throw new InvalidOperationException(
        "Register the host's IFacilityOperations implementation before calling AddDmrpModule.");

- Around line 112-126: Update
Excludes_an_enrolled_measure_that_has_no_dqm_mapped so the NEWMEASURE entry uses
a reported frequency such as Monthly instead of Frequency.Adhoc, while
preserving its empty DQM value and existing assertions. This ensures exclusion
is validated by the DqmsFor empty-DQM filter rather than by unsupported
frequency.

…is-ordered module registration

- Add unit coverage for MeasureMappingManager's IsStillReferenced backstop, which
  handles the window between the pre-check and the delete. A SQLite foreign key
  failure (787) and a not-null failure (1299) both surface as
  MeasureMappingInUseException, a failure buried two levels deep still does, and an
  unrelated failure does not. SQL Server's 547 and 515 cannot be reached from a
  test: SqlException has no public constructor and is only ever produced by the
  driver.
- Refuse AddDmrpModule when the host has registered neither IFacilityOperations nor
  its implementation type. RemoveAll on a service nobody registered removes nothing
  and reports nothing, so calling the module before the host registered its
  operations left the host's registration appended afterwards and winning the
  resolve: DMRP enabled with none of its facility behavior and no sign of it.
- Give the missing-dQM exclusion test a frequency the schedule has a bucket for, so
  the dQM filter is what excludes the entry rather than the frequency mismatch, and
  cover the adhoc frequency in a test of its own.
- Drop a single-use intermediate list when logging unmapped measures.
…RP is enabled

The automation stack posted a facility's scheduled reports with the facility, which
DMRP refuses, so every Automation.UI scenario run failed at setup with the module
enabled. The Backend E2E suites are thin clients of Automation.UI's run API, so they
failed for the same reason and in the same place.

- Detect DMRP by asking rather than by configuration. A disabled module strips its own
  controllers from the host, so api/dmrp/reporting-plans answers 404 when it is off and
  200 when it is on. An answer that is neither stops the run naming the request that
  failed, rather than guessing and stranding it later.
- With DMRP off, post the schedule with the facility exactly as before. With it on,
  create the facility with an empty schedule, enroll it in a measure mapping per
  measure, then save it again so Tenant derives the schedule from those reporting
  plans. Neither ordering works on its own: the schedule is derived when the facility
  is saved, but a reporting plan is refused for a facility that does not exist yet.
- Map each measure to itself monthly. The run drives the pipeline with the measure's
  own id, so the derived schedule names what the report types name and both paths leave
  the same facility behind. That is what keeps the tenant database validator unchanged.
- Enroll for the following reporting period as well as the current one, so a run that
  crosses midnight on the first of a month does not derive an empty schedule from a
  period nothing was enrolled for.
- Reuse a measure mapping that already exists, including one created concurrently.
  Mappings are shared by every run against a stack, so creating one is a race a run can
  lose without having failed.
- Fix SearchMeasureMappingsAsync, which read the measure-mapping collection route. That
  route only accepts POST, so the call answered 404 - indistinguishable from the module
  being switched off - and it had no consumers to notice. Add the measure, dQM and
  frequency filters the API already supports.
- Correct the DMRP switch comment in docker-compose.yml: the E2E suite no longer forces
  the module off, and appsettings is baked into the tenant image, so changing the flag
  needs a rebuild rather than just recreating the container.

Dispositions for the remaining review-body items, so nothing is left ambiguous.

Taken (503bab0)

  • IsStillReferenced backstop coverage. Added: SQLite foreign-key (787) and not-null (1299) failures both surface as MeasureMappingInUseException, a failure nested two levels deep still does — which is what makes the chain walk load-bearing rather than a plain InnerException check — and an unrelated failure (SQLITE_BUSY) does not. The SQL Server codes the same backstop recognises (547, 515) cannot be reached from a test: SqlException has no public constructor and is only ever produced by the driver. That's recorded in the test's doc comment so the omission reads as deliberate.
  • Registration-order hazard around RemoveAll<IFacilityOperations>(). Guarded. The check accepts either the interface or the host's implementation type being registered, rather than only the interface — DmrpIntegrationTestFixture legitimately supplies the host by concrete type, and a narrower check would have broken it while still not catching anything extra.
  • The intermediate unmapped list. Removed.

Not taking

  • Redundant facility read in TenantFacilityOperations.SoftDeleteAsync. The duplicate read is real, but threading the already-loaded facility through IFacilityOperations would couple the seam to the order the controller happens to do things in, to save one read on a delete. Not a good trade.

Backlog rather than blockers

  • Moving IFacilityOperations out of the DMRP assembly. Valid direction and consistent with DotNet/Shared being the contract layer, but Tenant.csproj already carried a ProjectReference to DMRP.csproj on dev — this PR widened an existing inversion rather than introducing one.
  • A real-host rollback integration test. Checked the assumption it would be guarding: FacilityRepository and the module's EntityRepository<FacilityReportingPlan, TenantDbContext> are both scoped over the same TenantDbContext, so one transaction genuinely does span the host's write and the module's. The design holds by construction; a test would guard a future regression, such as a move to IDbContextFactory, rather than a present gap. Noting it here so the reasoning survives.

The DMRP module's endpoints were the only service surface API Health did not exercise,
so the behaviours added for this story - a conflict when deleting a referenced measure
mapping, a refused facility schedule, no-content on an empty search - sat outside the
suite CI runs.

- Add a DMRP suite covering measure mapping and reporting plan CRUD, their error paths,
  and the one endpoint DMRP changes without owning: a facility that carries its own
  schedule is refused while the module is enabled.
- Ask the Tenant service whether DMRP is registered rather than reading a flag. A
  disabled module strips its own controllers, so its routes answer 404, and the suite
  reports its steps as skipped rather than failing a stack that simply is not running
  DMRP. This keeps the switch in one place instead of adding a copy here.
- Declare no seed requirement. Seeding runs a full pipeline scenario before any suite
  executes, which is a minute or two of waiting that buys this suite nothing and is
  wasted entirely whenever DMRP is switched off. The two fixtures it needs are cheap to
  obtain directly: a dQM MeasureEval already holds, and a facility of its own that it
  removes when it is done. Running the suite drops from about two minutes to one second.
- Stop counting skipped steps against a service on the API Health dashboard. The badge
  showed passed-over-total with skipped steps in the denominator and the same grey as a
  run in progress, so a service whose steps all skipped read as one that was still
  going. Skipped steps now leave the denominator and a fully skipped service says so.
  Steps that never ran stay in it, so pending and skipped no longer look alike.

The description says:
"No BFF changes, and no new routes. The ADR's BFF Reverse Proxy and Shared Interface section was written when DMRP was expected to be a separately deployed service."

But in the ADR I read :
"A new DMRP C# project should be created in the Link Cloud codebase. This is intended to be a project that enables additional functionality on the Tenant service and is not going to be a separately deployed service."

They seem to be contradictory.

@arianamihailescu
DMRP is a new project, and Tenant uses DMRP implementations when DMRP is active. New routes support DMRP-specific items, but the existing routes should work as before. I did have to make a change so that adding a Tenant wouldn't fail with DMRP enabled. I suspect LEGLINK-707 will change this.

…report

The rule predated DMRP and is removed at a reviewer's suggestion on this PR. It also could
not coexist with DMRP: the schedule is derived from a facility's reporting plans and the
Tenant API refuses a facility that supplies its own, so with the rule in force there was no
input the form could produce that the API would accept. The DMRP work routed around it by
making the rule conditional; removing it outright takes the contradiction out at the source.

- ScheduledReportsValidator now checks one thing, that no report is named twice, and no
  longer takes the DMRP flag. Its errors accumulator went with the second rule.
- Drop the noReportsEntered getter and the error it rendered on the facility form.
- Cover a duplicate repeated within a single period, which the spec had not exercised.

The DMRP flag stays in the UI: it still hides the report pickers and submits an empty
schedule, the latter mattering on edit, where the form loads a facility's stored schedule
into the controls and would otherwise send it back to an API that refuses it. Its
retirement recipe loses the step for the validator parameter.

Note this also applies with DMRP disabled, where the form was the only thing preventing a
facility from being saved with no scheduled reports. The API has always allowed it -
ScheduleService treats an empty array as "create no job for this frequency" - so such a
facility can now be created from the UI and will run no scheduled reports.
