📝 WalkthroughWalkthroughThis pull request adds TiCI (TiDB Cloud Index), a full-text search subsystem. It changes the parser grammar, DDL for FULLTEXT and HYBRID indexes, a TiCI RPC client and cloud writer, lightning and ingest wiring, distsql and executor scan paths, a new expression fulltext query engine, planner routing and statistics, KV and store shard caching, table codec changes, session variables, and integration tests. It also hardens the GCS storage client to force HTTP/1.1. ChangesTiCI Full-Text Search Integration

reserve_port writes the diagnostic message to stdout, so callers capture a multi-line port value.
Line 255 prints the "in use" message to stdout. Line 257 prints the candidate to stdout. Callers read stdout with command substitution, for example MINIO_PORT=$(reserve_port "minio" "$MINIO_PORT") on line 271 and port=$(reserve_port "auto" "$start") on line 237.
When the requested port is busy, the caller receives both lines. MINIO_PORT then becomes minio port 9000 is in use; using 9001 followed by 9001. Every downstream use breaks, including MINIO_ENDPOINT, the S3 sink URI, and the reserve_port arithmetic in alloc_port (NEXT_PORT=$((port + 1))).
Send the message to stderr.

Keep the TiCI writer interface nil for tables without TiCI indexes, and cover the initializer regression. Review the four added FTS builtins and update the registry snapshot without relaxing null-reject proofs. Remove an extra test blank line and normalize go.sum through tidy. Signed-off-by: AilinKid <314806019@qq.com>
Restore inline Hybrid metadata and option validation, reject non-KV indexes for foreign keys, and exclude TiCI indexes from remote checksum requests. Validate stable local MATCH literals during planning and preserve each existing index's analyzer settings when adding partitions. Restore the missing Hybrid DDL job statistics settings. Add regression coverage for metadata identity, malformed literals on empty inputs, foreign-key index selection, partitioned checksum requests, and partition analyzer settings including jobs without session variables.

Persist custom stopwords with the FULLTEXT index.
ParserConfig replaces only scalar settings. buildTiCIFulltextParserInfo then reads custom stopwords from the partition-add job and its current stopword table. If that setting or table content changes after index creation, new partitions use a different analyzer than existing partitions. This can produce partition-dependent search results and changed retry group keys.
Store an immutable stopword snapshot with the index metadata, or reject partition addition for indexes that use custom stopwords until the original analyzer can be reproduced.

Inherit TiDB dependency replacements when compiling standalone plugins, using temporary module files to preserve the plugin checkout. Cover the missing API failure and nested plugin directories with an offline build test. Keep the release vector-index errors for DROP and MODIFY COLUMN while retaining the TiCI guards. Update the legacy FULLTEXT-ignore SQL fixture to check failed DDL rollback without a TiCI service. Prepare subscription checkpoints before starting the idle timer, and avoid an Eventually callback racing deferred subscriber cleanup. Signed-off-by: AilinKid <314806019@qq.com>

Use the source FTS index type value for CREATE and ALTER FULLTEXT without renumbering existing release index types. Preserve local analyzer configuration snapshots and verify both serialized TiCI requests and published metadata. Validated focused DDL/local MATCH tests, parser model tests, make lint, and 34 SQL statements against real TiCI. The old binary reproduces Unsupported index type: 1. Local TiCI requires CDC date-separator=none; full parser target remains blocked by pre-existing parser.y formatting.

What problem does this PR solve?
Issue Number: ref #68703
Provide a release-8.5 draft PR for building and validating the FTS/TiCI stack ported onto TiDB v8.5.8. This branch selectively backports the required
release-fts-202602functionality and adds the agreed local FTS evaluation alternative.What changed and how does it work?

Keep this PR in draft for coordinated development image builds. The TiCI meta/worker version, PD compatibility and deployed TiCDC version must be fixed before claiming full-stack readiness.
Check List
Tests:
Focused Go/Bazel checks were run throughout the backports. The final local-alternative validation passed 20 test items, followed by 12 local-MATCH regression items for the HAVING test addition. A fresh standalone server was built from
f0e89cd9a43f9715f8f94502969e4feb7ee846c4using the committed release etcd compatibility helper.Companion mysql-test cases were recorded and verified against this binary. The pre-existing blacklisted
information_schema_csfixture drift is documented in the companion PR. These checks do not establish full MySQL FTS parity or real TiCI service end-to-end compatibility. No full-suite or cross-component E2E run is claimed.Documentation / behavior:
