jcoffey-dev 088677643f Close search's active-tenant write-routing gap with a polled allowlist
search/src/consumer.rs's write-routing (built last pass) had no active-
tenant check at all: IndexRegistry.resolve() would open-or-create an
index directory for any syntactically-valid tenant_id, active or not --
unlike ClickHouse's chwriter.Registry (an active-tenants-only snapshot
built at enterprise-ingest startup) or the read side (gated by
searchclient.TenantChecker, a direct rbacstore query). search is AGPL
core with no Postgres access and no enterprise/ import allowed, so it
needed a network boundary instead -- the same shape ingest's
TenantResolver already uses against enterprise-auth, just Rust calling
Go instead of Go calling Go.

New GET /internal/active-tenants endpoint on enterprise-auth
(rbacstore.ListActiveTenantIDs + authhandler.handleActiveTenants),
gated on a RoleService Bearer credential -- server-to-server auth, the
same shape alerting presents to api, minted via the already-generic
enterprise-auth -mint-service-token search. search/src/tenants.rs's
ActiveTenantTracker polls it every 60s, blocking startup on the first
fetch succeeding (fail-closed cold start -- a control-plane outage at
boot must not silently accept every tenant_id) and keeping the last-
known-good set on any later refresh failure (a transient blip shouldn't
stop every tenant's indexing, only prevent the allowlist from growing/
shrinking until connectivity resumes). consumer.rs refuses any tagged
record whose tenant isn't in the polled set, before ever calling
resolve() -- IndexRegistry itself stays policy-free, matching the same
mechanism/policy split clickhousewriter.Writer vs. chwriter.Registry
already draws on the ClickHouse side.

Off unless ENTERPRISE_AUTH_URL/ENTERPRISE_AUTH_SERVICE_TOKEN are both
set (search/src/config.rs rejects exactly one being set) -- every
existing deployment is unaffected.

Verified with real HTTP round trips in this environment: tenants.rs's
tests exercise real reqwest requests (actual Authorization: Bearer
header, actual JSON parsing) against a hand-rolled dependency-free TCP
test server, including both fail-closed paths (rejected first fetch,
unreachable server). authhandler's new tests cover the credential-kind
distinction this endpoint exists to enforce -- a real human session,
even for a genuine Owner, must not satisfy a check meant for a service
identity.

One asymmetry remains, disclosed rather than fixed: chwriter.Registry's
snapshot still never refreshes (stale until enterprise-ingest restarts),
while ActiveTenantTracker's 60s poll gives Tantivy a materially tighter
staleness window. Neither is a live per-write check -- that would mean
a database/HTTP round trip per record, a throughput cost neither
implementation accepts -- so both have some staleness window by design;
the gap between the two windows is what's disclosed, not a claim either
is fully live.

jcoffey-dev bdd42e06f6 Build per-tenant Tantivy write-routing, closing the last ingest write gap
search/src/consumer.rs now resolves each record's tenant_id Kafka header
through the same IndexRegistry the read side (search/src/registry.rs +
enterprise/internal/searchclient) already used, and writes into that
tenant's own index instead of always the default one. The periodic
Tantivy commit now commits every tenant index that's actually seen a
write (IndexRegistry::commit_all), not just the default index.

Unlike ClickHouse, this needed no "second binary": Tantivy has no grant
system to gate a commercially-licensed credential behind, so
IndexRegistry already lived directly in this AGPL-core search binary --
there was never an import-boundary reason to split the write side into
an enterprise/ binary the way chwriter/enterprise-ingest was for
ClickHouse. Read and write simply share one registry.

Because Tantivy is an embedded library, this is genuinely verified in
this environment, not just written: registry.rs's
commit_all_commits_default_and_every_opened_tenant_index writes into the
default index plus two tenant indices, confirms nothing is searchable
pre-commit, then confirms all three are post-commit. consumer.rs's
tenant_id_from_headers is factored out as a small pure helper (mirroring
ingest/consumer.tenantIDFromHeaders) with its own unit tests, plus a
guard test against the "tenant_id" header-key literal drifting from the
Go side's -- the same guard-test pattern ingest/cmd/ingest already used
for its own two Go copies of the constant, now mirrored a third time
across the language boundary.

One gap is disclosed, not fixed, by this change: unlike chwriter.Registry
(an active-tenants-only snapshot built at enterprise-ingest startup, so
an unrecognized tenant_id is refused outright) and unlike the read side
(gated by searchclient.TenantChecker), this consumer's registry.resolve()
call has no active-tenant check at all -- search has no Postgres access
to check tenant status against. A still-valid-but-should-be-revoked
ingest credential can cause an index directory to be created for a
tenant that's no longer active. Narrow blast radius (an orphan, isolated,
empty index, not cross-tenant leakage, and only reachable with a real
signed credential), but real -- see registry.rs's doc comment on
resolve(). Closing it fully would mean giving search some way to learn
which tenants are active without an enterprise/ import, which isn't
designed yet.

This closes the last of Phase 4's ingest write-routing gaps (ClickHouse
was closed last commit). The one remaining gap in the whole phase is now
the tenant-picker frontend page, deliberately deferred earlier in this
phase as out of scope for this environment.

jcoffey-dev ba2276aa1a Phase 4: real Tantivy per-tenant isolation (search/src/registry.rs, enterprise/internal/searchclient)
Closes the last named "isolation mechanism" gap: search.proto gains a
tenant_id field on SearchRequest; search/src/registry.rs's IndexRegistry
resolves it to an on-demand-opened, per-tenant Tantivy index (empty
tenant_id keeps today's single default index, so this is purely
additive); enterprise/internal/searchclient sets that field from the
authenticated request identity in ctx, mirroring chrunner's exact
fail-closed "never a parameter" shape. Wired into enterprise-api in
place of the shared api/searchclient.

Unlike the ClickHouse pieces from the previous two commits, this one is
genuinely verified end to end in this environment: Tantivy is an
embedded library, not a networked service, so both the Rust index
registry (cargo test, cargo clippy --all-targets -- -D warnings, both
clean) and the Go client (a real in-process gRPC server) could actually
run. registry.rs's tenant_index_is_isolated_from_default_and_other_tenants
seeds three real indices with the same term and confirms a tenant-scoped
search returns only that tenant's document -- item 3 of the isolation
design doc's verification plan, closed for real, not just written.

With both ClickHouse and Tantivy isolation now built, the single largest
remaining gap is no longer a missing mechanism: it's that nothing forces
or flags whether a deployment actually runs enterprise-api instead of
plain api, and that ingest itself has no tenant concept for either
storage engine (every record still lands in the one shared database/
index no matter what -- undesigned, not just unbuilt). Updated the
threat model, architecture doc, CLAUDE.md, and both READMEs accordingly.

jcoffey-dev cd8aa290ca Phase 1: Windows log collection + full-text search
Extends the agent, ingest, storage, api, and web with Windows Event
Log/ETW sourcing and Tantivy-backed free-text search, per the approved
Phase 1 plan.

- CLAUDE.md: materialized on disk (never existed as a file before) with
  a new Phase 1 "done looks like" section.
- agent: Windows Event Log (EvtSubscribe) and ETW sources, Windows
  service wrapper (install/uninstall/run-service), both feature- and
  target_os-gated so Linux builds/tests/clippy stay unaffected. Also
  fixed two pre-existing Phase 0 clippy gaps (dead-code on
  default-features-only builds, a type-inference edge case) found while
  testing every feature combination properly for the first time.
  UNVERIFIED on real Windows -- no Windows toolchain existed anywhere in
  the build environment; flagged prominently in three places.
- proto/ingest: new record_id field, assigned once server-side in
  ingest's gRPC front end so ClickHouse and Tantivy agree on the same ID
  for the same record.
- storage: record_id column + bloom filter index, verified against a
  live ClickHouse.
- search: new service, Tantivy index, rskafka consumer as an independent
  second consumer group on the same Redpanda topic ingest already reads.
- api/web: new /search endpoint and page, sharing the query page's
  result-table shape and component.
- hack/windows-fixture: sends realistic Windows-shaped data straight to
  ingest, so the pipeline's handling of it is verifiable without a
  Windows host.

Verified end-to-end on the live docker-compose stack: the same record_id
comes back from both /query and /search for the same log line, including
for windows-fixture's synthetic Windows Event Log data. Real bugs found
and fixed along the way: api/Dockerfile missing proto/ in its build
context, search's logs being completely silent (RUST_LOG gap), and
search/target/ missing from .gitignore/.dockerignore.
