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.
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.
