Summary

Adds the filtered per-space indicator alias over .threat-intel-indicators. The alias enforces space_id and precision ioc_tier filters so Indicator Match rules do not rely on query-time discipline alone.

Scope review follow-up

Preserves the corrected .threat-intel-indicators namespace (not .kibana-threat-intel-indicators).

Product boundary

The alias narrows what a reader sees. It does not grant read access by itself. threatIntelSupplyEnabled stays off until direct-index cross-space isolation is hardened.

…ant them

The doc comment presented the filtered alias as making an index safe for an Indicator
Match rule to point at. That holds for the two things the alias filters, space and
tier, and says nothing about the third thing standing between a rule and the data.

An Indicator Match rule reads its threat index as the rule's own API key, which
inherits the author's Elasticsearch roles rather than their Kibana feature privileges
(`create_threat_signals.ts` uses `asCurrentUser` plus `openPointInTime`). Nothing in
this plugin grants an index privilege on the indicator index or its aliases, so a rule
pointed at one fails for every non-superuser until an operator grants `read` by hand.

That is a gap in the pipeline rather than a property of the alias, and the alias is
where an operator meets it, so it is documented here. Whether it stays a documented
manual grant or becomes a feature-privilege change is a product decision, not one to
settle in a comment.

…space

can grant its per-space aliases to Detection Engine rules. This updates the alias module
to match, and rewrites the access note to say where the grant now comes from rather than
describing it as an unfilled gap.

The test derives the index name from the constant instead of hardcoding it, so it follows
any future change. One property is pinned separately: the alias must stay outside
`.kibana`. That is what makes the grant possible, and nothing else in the suite would
catch a name drifting back.

@elasticmachine merge upstream

aliasFilterMatches compared only the first space_id and ioc_tier terms clauses and
never asserted the clause count, so a stored filter with a third terms clause or a
duplicate space_id was reported as matching and never repaired. It now requires
exactly the two recognized terms clauses, classified independently so an empty or
duplicate clause cannot be chosen ahead of the real one.

…og API (#287204)

## Summary

Adds LLM enrichment services and Threat Intelligence HTTP routes,
including the fixed-catalog source list and enable/disable API. Manual
report creation and provenance URLs go through the shared HTTP/HTTPS
normalizer.

Also wires the routes, inference features, and one-time bootstrap into
`plugin.ts`, gated by `threatIntelSupplyEnabled`. This wiring is
interim: it exists so the enrichment eval suite (see Evaluation below)
has routes to call ahead of the full pipeline wiring. `#287207` replaces
it with a proper `wiring.ts` module; that PR's description has a rebase
note covering the `plugin.ts` conflict resolution.

#287479 came first in the merge train and is already on `main`. The
numbered series (#287197#287207) stacks on top in dependency order.
#287199 (content parsing) was closed; IOC extraction ships its own
section-header classifier.

## Scope review follow-up

- Shared `normalizeProvenanceUrl` helper (HTTP/HTTPS only, strips
credentials, bounded length).
- Source create/delete routes removed. Updates may change only
`enabled`.
- Lists and mutations reject catalog IDs outside the approved set.
- Ensures the per-space indicator alias on `list_sources` (idempotent).

## Evaluation

A `@kbn/evals` suite exercises all four enrichment stages against the
BlackHat demo pack article text, posting each input directly to the
internal route and scoring the structured response. It runs as a tracked
baseline (scores recorded, no build-failing thresholds yet). Latest full
run, EIS Claude Sonnet 4.6 as model and judge, 1 repetition, 20
examples:

| Stage | Evaluator | Score |
|---|---|---|
| assess_relevance | IsIntelligenceMatch | 1.00 |
| assess_relevance | RelevanceShapeValid | 1.00 |
| classify_severity | SeverityExactMatch | 0.83 |
| classify_severity | SeverityWithinOneLevel | 1.00 |
| enrich_taxonomy | CategoryRecall | 0.80 |
| enrich_taxonomy | RegionRecall | 1.00 |
| extract_diamond | DiamondNoIocLeak | 1.00 |
| extract_diamond | DiamondSignalCount | 1.00 |
| extract_diamond | criteria (LLM judge, majority vote) | 1.00 |

The suite ships in #289345, a separate eval-only PR that stacks on this
one (it needs the routes and the flag-gated wiring added here). The four
deterministic routes are covered separately by Scout API tests in
#289343. Any prompt or calibration fix the evals surface lands by
amending this PR, not the eval PR.

## Summary

Wires Threat Intelligence behind `threatIntelSupplyEnabled`: bootstrap,
managed workflow installation, promote/scrub tasks, and route
registration. Promote mirrors extracted IOCs into
`.threat-intel-indicators` for Indicator Match rules.

#287479 came first in the merge train and is already on `main`. The
numbered series (#287197#287205) is merged; #287206 and #287207 now sit
directly on `main`. #287199 (content parsing) was closed; IOC extraction
ships its own section-header classifier.

## Scope review follow-up

- Installs the managed workflows with the right space topology:
`attribute_alerts_to_reports` installs per space (it queries
`.alerts-security.alerts-*` and writes per-space hit totals, so a global
install would clobber every space's totals onto one shared doc), while
`ingest_threat_feeds` and `enrich_threat_report` install once globally.
Alert analysis and threat intel share a single `ready()` call so neither
install set is dropped, and spaces created after boot are reconciled on
the promote task. All three ship `enabled: false`, and enrich routes its
HTTP calls through a fixed space (`default`) instead of the install-time
`workflow.spaceId` (which is `'*'` globally).
- Ensures the default-space indicator alias on start.
- Chunks promotion bulk writes and treats HTTP 408/500 as retryable bulk
failures.
- Sanitizes provenance and extracted IOC reference URLs during
promotion.
- Documents direct-index cross-space isolation as the blocker to
enabling the feature.

## Bootstrap fix folded in from #289343

`seed_default_sources.ts` sorted the legacy-source disable scan on
`_id`, which Elasticsearch rejects with `illegal_argument_exception:
Fielddata access on the _id field is disallowed` unless
`indices.id_field_data.enabled` is set, so it failed bootstrap on a
stock cluster. Found this while getting #289343's Scout suite green and
moved the fix here since this PR is the one wiring up bootstrap and
already needs `security-threat-hunting` review, so it isn't adding a
reviewer #289343 wouldn't otherwise need.

## Product boundary

`threatIntelSupplyEnabled` defaults to false. Do not enable until
direct-index cross-space isolation is hardened or the administrator
trust model is explicitly accepted.

## To test

```
node scripts/jest --config x-pack/solutions/security/plugins/security_solution/server/threat_intel/jest.config.js wiring.test.ts tasks/promote_threat_indicators.test.ts
