* test: add csv translator for insert expr
Introduce a dedicated top-level csv translator so fuzz insert expressions can be converted into writer-ready records through a structured path instead of ad-hoc formatting in targets.

* test: add csv dump session utilities
Introduce CSV dump env helpers and a session writer that creates run directories, emits seed metadata, and flushes staged CSV records for fuzz workflows.
Signed-off-by: WenyXu <wenymedia@gmail.com>
* test: bound csv dump buffer with auto flush
Parse readable buffer sizes from env and flush staged CSV records automatically when the in-memory threshold is reached to prevent unbounded growth during long fuzz runs.
Signed-off-by: WenyXu <wenymedia@gmail.com>
* test: flush csv dump before repartition validation
Wire csv dump session into the metric repartition fuzz flow so successful inserts are translated from insert expressions into CSV records during write loops and flushed to disk right before row validation.
Signed-off-by: WenyXu <wenymedia@gmail.com>
* test: keep csv dumps on failure and cleanup on pass
Capture run outcomes in metric repartition fuzz, remove dump directories only after successful validation, and retain dump paths on failures so CI and local investigations can use the same artifacts.

* test: align partial csv records with table headers
Keep append payload compact by storing partial insert-expression columns, then expand to full table-context headers at flush time and fill missing values with empty strings.

* test: capture table-scoped sql traces after execution
Record insert and repartition SQL only after successful execution, include started_at_ms and elapsed_ms in trace comments, and broadcast repartition events into every logical-table trace file for consistent debugging context.
Signed-off-by: WenyXu <wenymedia@gmail.com>
* test: harden sql trace comments and include create sql
Normalize multiline trace comments into valid SQL comment lines and append logical-table CREATE SQL to per-table traces for better timeline reconstruction during repartition debugging.

* test: scaffold writer control channel for barrier flow
Add Barrier/Resume/Stop control skeleton and channel wiring in write_loop to prepare per-repartition validation barriers. Also align SQL dump tests with broadcast SQL payload behavior.
Signed-off-by: WenyXu <wenymedia@gmail.com>
* test: implement writer barrier pause and resume control
Make writer control messages effective by pausing writes on barrier, resuming on resume, and stopping via channel signaling so the next commit can enforce deterministic per-repartition validation boundaries.
Signed-off-by: WenyXu <wenymedia@gmail.com>
* test: validate rows after each repartition barrier
Add per-action barrier/ack synchronization with timeout, run immediate logical-table row validation after each repartition, and resume writer only after validation completes to improve minimal failure localization.
Signed-off-by: WenyXu <wenymedia@gmail.com>
* test: flush dump sessions before per-epoch validation
Extract a shared flush-and-snapshot helper and call it before each immediate row validation so CSV/SQL artifacts are persisted at the same epoch boundary being validated.

* feat/allow-fuzz-input-override:
Add environment override for fuzzing parameters and seed values
- Implement `get_fuzz_override` function to read override values from environment variables for fuzzing parameters.
- Allow overriding `SEED`, `ACTIONS`, `ROWS`, `TABLES`, `COLUMNS`, `INSERTS`, and `PARTITIONS` in various fuzzing targets.
- Introduce new constants `GT_FUZZ_INPUT_MAX_PARTITIONS` and `FUZZ_OVERRIDE_PREFIX`.

* feat/allow-fuzz-input-override: Remove GT_FUZZ_INPUT_MAX_PARTITIONS constant and usage from fuzzing utils and tests
• Deleted the GT_FUZZ_INPUT_MAX_PARTITIONS constant from fuzzing utility functions.
• Updated FuzzInput struct in fuzz_migrate_mito_regions.rs to use a hardcoded range instead of get_gt_fuzz_input_max_partitions for determining the number of partitions.

* feat/allow-fuzz-input-override:
Improve fuzzing documentation with environment variable overrides
Enhanced the fuzzing instructions in the README to include guidance on how to override fuzz input using environment variables, providing an example for better clarity.
