Update JDBC removal plan: Steps 9b-10b done, 10c-10d scoped

- Steps 1-9a, 9b-prep: MERGED
- Steps 9b, 9c, 10a, 10b: Open with PRs
- Step 10c: Remove SFSession/SFBaseSession (always null, not replicable)
- Step 10d: Demote JDBC to test scope (27 remaining imports with
  massive dependency chains)

-### Step 9b — Replicate OOB telemetry infrastructure ⬜ TODO
+### Step 9b — Replicate OOB telemetry infrastructure ✅ (PRs #1129, #1130)
 
-Replicate the OOB (out-of-band) telemetry classes that
-`SnowflakeSQLLoggedException` depends on. Verbatim replication — no stubs,
-no logic changes.
+**Done (PR #1129 — prep, MERGED):**
+- `TelemetryThreadPool` (61 lines) — singleton thread pool
+- `SFTimestamp` (20 lines) — UTC timestamp formatter
+- `SnowflakeConnectString` (256 lines) — connection string parser
+- `SnowflakeDriverConstants` — constants from LoginInfoDTO/SnowflakeDriver
 
-**Classes to replicate (~1170 lines total):**
-- `TelemetryThreadPool` (61 lines) — singleton thread pool for async telemetry.
-  No JDBC deps beyond package.
-- `SFTimestamp` (20 lines) — UTC timestamp formatter. No JDBC deps.
-- `SnowflakeConnectString` (256 lines) — connection string parser. Deps:
-  `SFSessionProperty` (already replicated), `SecretDetector` (already
-  replicated), `SFLogger` (already replicated).
-- `TelemetryEvent` (182 lines) — telemetry event builder. Deps:
-  `SFException` (JDBC, kept temporarily), `UUIDUtils` (already replicated),
-  `SFTimestamp` (replicated above), `SecretDetector` (already replicated),
-  `ResourceBundleManager` (already replicated).
-- `TelemetryService` (651 lines) — OOB telemetry singleton. Deps:
-  `SnowflakeConnectString` (replicated above), `SecretDetector` (already
-  replicated), `Stopwatch` (already replicated), `TelemetryThreadPool`
-  (replicated above).
+**Done (PR #1130 — main, Open):**
+- `TelemetryEvent` (182 lines) — telemetry event builder
+- `TelemetryService` (651 lines) — OOB telemetry singleton
+- `version.properties` — resource bundle for driver version
 
-**Also add constants:**
-- `LoginInfoDTO.SF_JDBC_APP_ID` = `"JDBC"` (from snowflake-common)
-- `SnowflakeDriver.implementVersion` = `"3.25.1"` (version string)
+---
+
+### Step 9c — Swap telemetry imports ✅ Open (PR #1131)
+
+**Done:** Mechanical import swaps only:
+- `SnowflakeSQLLoggedException`: swapped 6 of 12 JDBC imports
+  (ObjectMapperFactory, SqlState, TelemetryEvent, TelemetryService,
+  LoginInfoDTO→SnowflakeDriverConstants, SnowflakeDriver→SnowflakeDriverConstants).
+  Kept 6: SFBaseSession, SFSession (parameter types), Telemetry,
+  TelemetryField, TelemetryUtil (interact with session.getTelemetryClient()).
+- `TelemetryClient`: swapped TelemetryThreadPool. Kept 4: HttpUtil,
+  SFSession, SnowflakeConnectionV1, SnowflakeSQLException.
+
+---
 
-**Suggested PR split (~200 lines production code per PR):**
-- PR 1: `TelemetryThreadPool`, `SFTimestamp`, `SnowflakeConnectString`,
-  constants (~340 lines)
-- PR 2: `TelemetryEvent`, `TelemetryService` (~830 lines — single class
-  exceeds 200-line limit, OK per plan rules)
+### Step 10a — Replicate remaining small JDBC classes ✅ Open (PR #1132)
+
+**Done:** Verbatim replication of self-contained classes:
+- `SFException` (127 lines) — exception type
+- `HttpResponseContextDto` (54 lines) — HTTP response context
+- `TimeMeasurement` (53 lines) — epoch microsecond timer
+- `ExecTimeTelemetryData` (199 lines) — execution time telemetry
+- `ThrowingCallable` (9 lines) — functional interface
+- `StorageClientUtil`: added `getEpochTimeInMicroSeconds`

-### Step 9c — Swap telemetry imports in SnowflakeSQLLoggedException + TelemetryClient ⬜ TODO
+### Step 10b — Swap SFException imports ✅ Open (PR #1134)
+
+**Done:** Removed `SFException` JDBC imports from 3 files where the
+replicated `SFException` is now in the same package:
+- `SnowflakeSQLException`, `SnowflakeSQLLoggedException`, `TelemetryEvent`
 
-Mechanical import swaps only — no logic changes, no method removal:
-- `SnowflakeSQLLoggedException`: swap all 12 JDBC telemetry imports to
-  ingest replicated versions (from Step 9b). Full `sendTelemetryData()`
-  body preserved verbatim.
-- `TelemetryClient`: swap `TelemetryThreadPool` to ingest version
-  (from Step 9b). Remaining JDBC imports (`HttpUtil`, `SFSession`,
-  `SnowflakeConnectionV1`, `SnowflakeSQLException`) kept until Step 10.
+`ExecTimeTelemetryData`/`HttpResponseContextDto` in `SnowflakeGCSClient`
+NOT swapped — they interact with JDBC's `RestRequest.executeWithRetries()`.

-### Step 10 — Remove JDBC Dependency ⬜ TODO
+### Step 10c — Remove SFSession/SFBaseSession ⬜ TODO
+
+SFSession/SFBaseSession are always null from ingest callers. Not feasible
+to replicate (1498+1404 lines, 156-class transitive closure = 40K lines).
+Need to remove these parameter types.
+
+---
 
-Remaining JDBC imports after Step 9c (all in `fileTransferAgent/`):
-- `SFSession`/`SFBaseSession` (15 imports) — always null from callers.
-  Need stubs or parameter type changes.
-- `SFException` (2 imports) — used in one `SnowflakeSQLException` constructor
-  (never called) and caught in `parseCommandInGS` (calls JDBC's `SFStatement`).
-- `SnowflakeConnectionV1`, `SnowflakeSQLException` in `TelemetryClient`
-  — session-based code path, never used by ingest.
-- `HttpUtil` in `TelemetryClient` — `executeGeneralRequest` for both
-  session and sessionless paths.
-- GCS HTTP types (4 imports) — `ExecTimeTelemetryData`, `HttpResponseContextDto`,
-  `HttpUtil`, `RestRequest` in `SnowflakeGCSClient`.
+### Step 10d — Demote JDBC to test scope ⬜ TODO
+
+Remaining 27 JDBC imports after Step 10b (all unreplicable due to massive
+dependency chains):
+- `SFSession`/`SFBaseSession` (15) — parameter types, always null
+- `HttpUtil` (2) — GCS client + TelemetryClient
+- `RestRequest` (1) — GCS client
+- `SnowflakeConnectionV1` (1) — TelemetryClient session path
+- `SnowflakeSQLException` (JDBC's, 1) — TelemetryClient
+- `ExecTimeTelemetryData`/`HttpResponseContextDto` (2) — GCS client
+  (replicated but interact with JDBC RestRequest)
+- IB `Telemetry`/`TelemetryField`/`TelemetryUtil` (3) —
+  interact with session.getTelemetryClient()
+- `SFSession` in `SnowflakeSQLLoggedException` (2) — parameter types
 
 Then:
-1. Create `SFSession`/`SFBaseSession` stubs or change parameter types
-2. Replace remaining JDBC HTTP utilities with direct Apache HttpClient
-3. Change `snowflake-jdbc-thin` scope to `test` in `pom.xml`
-4. Remove JDBC shade relocation rules from Maven Shade plugin
-5. Remove `snowflake-jdbc-thin` from `public_pom.xml`
-6. Run full test suite
+1. Demote `snowflake-jdbc-thin` to `test` scope in `pom.xml`
+2. Remove JDBC shade relocation rules from Maven Shade plugin
+3. Remove `snowflake-jdbc-thin` from `public_pom.xml`
+4. Run full test suite
