Update HISTORY and bump version

Summary:
With https://github.com/facebook/rocksdb/issues/10087, applications calling `SyncWAL()` or writing with `WriteOptions::sync=true` can suffer
from performance regression. This PR reverts to original behavior of tracking the syncing of closed WALs.
After we revert back to old behavior, recovery, whether kPointInTime or kAbsoluteConsistency, may fail to
detect corruption in synced WALs if the corruption is in the live WAL.

-// Shared PR comment posting utility.
-// Used by both clang-tidy-comment.yml and claude-review-comment.yml.
-//
-// Usage from actions/github-script:
-//   const post = require('./.github/scripts/post-pr-comment.js');
-//   await post({ github, context, core, prNumber, body, marker });
-//
-// Parameters:
-//   github   - octokit instance from actions/github-script
-//   context  - GitHub Actions context
-//   core     - @actions/core for logging
-//   prNumber - PR number to comment on
-//   body     - comment body (markdown string)
-//   marker   - HTML comment marker for dedup (e.g. '<!-- claude-review -->')
-//              If an existing comment with this marker is found, it is updated.
-//              If not found, a new comment is created.
-//   legacyMarkers - optional list of legacy markers that should be migrated by
-//              being considered part of the same comment family.
-//   prunePrefix - optional marker prefix whose older comments should be
-//                 superseded. If obsoleteTitle is set, older comments are
-//                 collapsed instead of deleted.
-//   preserveLatest - optional count of active comments to keep when
-//                    prunePrefix is set.
-//   obsoleteMarker - optional HTML marker used to detect already-obsolete
-//                    comments.
-//   obsoleteTitle - optional heading to use when collapsing superseded
-//                   comments into a details block.

-# RocksDB Code Generation and Review Guidance
-
-This document provides guidance for generating and reviewing code in the RocksDB project, derived from analysis of code review feedback across hundreds of complex merged Pull Requests. Use this as a reference when writing code with AI assistants or conducting code reviews.
-
----
-
-## General Best Practices
-
-### Code Quality and Maintainability
-
-**Clarity and Readability:** Write clear, self-documenting code. Use meaningful variable names, add comments for complex logic, and structure code to minimize cognitive load. Avoid clever tricks that sacrifice readability for marginal performance gains unless absolutely necessary.
-
-**Consistent Style:** Follow existing code style conventions. RocksDB uses `.clang-format` for formatting, specific naming conventions, and structural patterns. Deviations from these patterns are frequently flagged in reviews.
-
-**Error Handling:** Ensure robust error handling throughout the codebase. Use RocksDB's `Status` type consistently, propagate errors appropriately, and avoid silently ignoring failures. Reviewers pay close attention to edge cases and failure modes.
-
-### Testing Philosophy
-
-**Comprehensive Coverage:** Every change should include appropriate test coverage. This includes unit tests for isolated functionality, integration tests for component interactions, and stress tests for concurrency and performance validation. Reviewers will ask for additional tests if coverage is insufficient.
-
-**Edge Cases and Failure Modes:** Tests should explicitly cover edge cases, boundary conditions, and potential failure scenarios. This is especially important for changes affecting core database operations, compaction, or recovery logic.
-
-**Platform-Specific Testing:** RocksDB supports multiple platforms (Linux, Windows, macOS) and compilers (GCC, Clang, MSVC). Changes should be tested across relevant platforms, particularly when touching platform-specific code or using compiler-specific features.
-
-### Performance Considerations
-
-**⚠️ PERFORMANCE IS CRITICAL:** RocksDB is a high-performance storage engine where every CPU cycle and memory access matters. When writing code, always evaluate from a performance perspective. This is not optional—performance-aware coding is a fundamental requirement for all contributions.
-
-**Benchmarking and Profiling:** Performance claims should be backed by empirical evidence. Use RocksDB's benchmarking tools (e.g., `db_bench`) to validate improvements. Reviewers will request benchmark results for changes that could impact performance.
-
-**Memory Allocation:** Minimize dynamic memory allocations, especially in hot paths. Prefer stack allocation over heap allocation. Reuse buffers when possible. Consider using arena allocators or memory pools for frequent small allocations. Every `new`, `malloc`, or container resize has a cost.
-
-**Memory Copy:** Avoid unnecessary memory copies. Use move semantics, `std::string_view`, `Slice`, and pass-by-reference where appropriate. Be aware of implicit copies in STL containers and function returns. Prefer in-place operations over copy-and-modify patterns.
-
-**CPU Cache Efficiency:** Design data structures and access patterns to be cache-friendly. Keep frequently accessed data together (data locality). Prefer sequential memory access over random access. Be mindful of cache line sizes (typically 64 bytes) and avoid false sharing in concurrent code. Consider struct packing and field ordering to improve cache utilization.
-
-**Loop Optimization:** Look for opportunities to collapse nested loops, reduce loop overhead, and minimize branch mispredictions. Hoist invariant computations out of loops. Consider loop unrolling for tight inner loops. Batch operations when possible to amortize per-operation overhead.
-
-**SIMD and Vectorization:** Leverage SIMD instructions (SSE, AVX) for data-parallel operations when appropriate. Structure data to enable auto-vectorization by the compiler. Consider explicit SIMD intrinsics for critical hot paths like checksum computation, encoding/decoding, and bulk data processing.
-
-**Branch Prediction:** Minimize unpredictable branches in hot paths. Use `LIKELY`/`UNLIKELY` macros to hint branch prediction. Consider branchless alternatives for simple conditionals. Order switch cases and if-else chains by frequency.
-
-**Memory and Resource Management:** Be mindful of memory allocations, especially in hot paths. Use RAII patterns, smart pointers, and RocksDB's memory management utilities appropriately.
-
-**Hot Path Analysis:** When deciding how aggressively to optimize code, consider whether it's on a hot path:
-- **Hot path** (executed thousands+ times, e.g., data access, iteration, compaction loops): Performance is paramount. Apply all optimization techniques—loop collapsing, SIMD, cache optimization, pre-allocation, etc. The cost of each operation is multiplied by execution frequency.
-- **Cold path** (executed rarely, e.g., DB open, configuration parsing, error handling): Maintainability and clarity are more important. Prefer readable code over micro-optimizations. Complex optimizations here add maintenance burden with negligible performance benefit.
-- **Warm path** (moderate frequency): Balance both concerns. Use profiling data to guide optimization decisions.
-
-**Avoid Premature Optimization:** While performance is critical, focus on correctness first, then optimize based on profiling data. However, be performance-aware from the start—choosing the right algorithm and data structure upfront is not premature optimization. Use the hot path analysis above to decide how much optimization effort is warranted.
-
-### API Design and Compatibility
-
-**Backwards Compatibility:** RocksDB maintains strong backwards compatibility guarantees. Breaking changes are rare and require extensive justification. When deprecating features, follow the project's deprecation policy (typically spanning multiple releases).
-
-**API Consistency:** New APIs should be consistent with existing patterns. Use similar naming conventions, parameter ordering, and return types. Reviewers will suggest changes to improve consistency with the broader codebase.
-
-**Documentation:** Public APIs must be thoroughly documented. Include usage examples, parameter descriptions, and notes on thread safety, performance characteristics, and compatibility considerations.
-
----
-
-## Component-Specific Guidance
-
-### Database Core (`db`)
-
-The database core handles write-ahead logging (WAL), memtables, compaction, and recovery. This component receives the most scrutiny in code reviews.
-
-**Concurrency and Thread Safety:** Database operations are highly concurrent. Reviewers carefully examine locking strategies, atomic operations, and memory ordering. Document synchronization assumptions clearly. Use appropriate memory ordering semantics (`acquire`/`release` vs. `seq_cst`).
-
-**Compaction Logic:** Changes to compaction are complex and high-risk. Ensure that compaction logic respects configured parameters, handles edge cases (empty databases, single-file compactions), and maintains correctness under concurrent operations.
-
-**Error Propagation:** Database operations can fail in many ways (I/O errors, corruption, resource exhaustion). Ensure that errors are properly propagated, logged, and handled. Avoid assertions in production code paths.
-
-**Testing:** Database core changes require extensive testing, including unit tests, integration tests, and stress tests. Test with various configurations, compaction styles, and concurrent workloads.
-
-### Public Headers (`include`)
-
-Public headers define RocksDB's API surface. Changes here have the highest compatibility impact.
-
-**API Design:** New APIs should be intuitive, consistent with existing patterns, and well-documented. Consider how the API will be used in practice and avoid adding unnecessary complexity.
-
-**Backwards Compatibility:** Breaking changes to public APIs require extensive justification and a deprecation plan. Maintain ABI compatibility for bug fixes and patch releases.
-
-**Documentation:** Every public API must be thoroughly documented with usage examples, parameter descriptions, and notes on thread safety and performance characteristics.
-
-**Deprecation:** When deprecating APIs, follow the project's policy. Mark deprecated APIs clearly, provide migration guidance, and maintain support for at least one major release.
-
-### Internal Utilities (`util`)
-
-Internal utilities provide common functionality used throughout the codebase.
-
-**Code Reuse:** Utilities should be general-purpose and reusable. Avoid duplicating functionality that already exists elsewhere in the codebase.
-
-**Error Handling:** Utility functions should handle errors robustly and propagate them appropriately. Consider edge cases like overflow, underflow, and invalid inputs.
-
-**Testing:** Utility functions should have comprehensive test coverage, including edge cases and failure modes. Consider adding death tests for assertions.
-
-**Performance:** Utilities are often used in hot paths. Ensure that implementations are efficient and avoid unnecessary allocations or copies.
-
-### Table Management (`table`)
-
-Table management handles SST file format, block-based tables, and table readers/writers.
-
-**Block Format and Checksums:** Changes to block format require extreme care. Ensure that checksums are computed and verified correctly. Test with various compression algorithms and block sizes.
-
-**Iterator Correctness:** Table iterators are used throughout the codebase. Ensure that iterator semantics (Seek, Next, Prev) are correct, especially at boundaries and with deletions.
-
-**Caching and Prefetching:** Table readers interact with the block cache and prefetching logic. Ensure that cache keys are unique and that prefetching respects configured limits.
-
-**Performance:** Table operations are performance-critical. Benchmark changes that could impact read or write performance.
-
-### Utilities (`utilities`)
-
-Utilities include optional features like transactions, backup engine, and checkpoint.
-
-**Feature Isolation:** Utilities should be self-contained and not introduce unnecessary dependencies on core database internals.
-
-**Deprecation and Cleanup:** Legacy features are being phased out. When removing deprecated code, ensure that migration paths are documented and that users have sufficient warning.
-
-**Cross-Platform Compatibility:** Utilities often interact with OS-specific APIs. Ensure that code works on all supported platforms.
-
-### Options and Configuration (`options`)
-
-Options define RocksDB's configuration system.
-
-**Type Safety:** Use appropriate types for options (e.g., `uint32_t` for flags, scoped enums for enumerated values).
-
-**Deprecation Policy:** When deprecating options, follow the project's policy. Document the deprecation, provide migration guidance, and maintain support for at least one major release.
-
-**Dynamic Configuration:** Some options can be changed dynamically. Ensure that dynamic changes are thread-safe and take effect correctly.
-
-**Validation:** Validate option values and provide clear error messages for invalid configurations.
-
-### Cache (`cache`)
-
-Cache management is critical for RocksDB's performance.
-
-**Concurrency:** Cache operations are highly concurrent. Ensure that implementations are thread-safe and use appropriate synchronization primitives.
-
-**Performance:** Cache operations are in the hot path. Optimize for low latency and high throughput. Benchmark changes carefully.
-
-**Memory Management:** Cache implementations must manage memory carefully to avoid leaks and excessive allocations.
-
-**Eviction Policies:** Changes to eviction policies should be well-tested and benchmarked to ensure they improve overall performance.

-## Common Review Feedback Patterns
-
-The following patterns emerged as frequent sources of review feedback:
-
-1. **Test Coverage:** Reviewers frequently request additional tests for edge cases, platform-specific behavior, and failure modes. Complex changes require comprehensive test coverage including unit tests, integration tests, and stress tests.
-
-2. **Error Handling:** Ensure proper error propagation using RocksDB's `Status` type. Avoid silent failures and provide clear error messages that include context about what failed and why.
-
-3. **API Design:** New APIs should be consistent with existing patterns. Use descriptive names that follow established conventions. Avoid breaking changes without strong justification and a clear deprecation plan.
-
-4. **Documentation:** Public APIs must be documented with usage examples and notes on thread safety, performance characteristics, and compatibility considerations. Complex internal logic should also be well-commented.
-
-5. **Performance:** Performance-sensitive changes require benchmark results to validate improvements. Use `db_bench` and other profiling tools to measure impact. Avoid premature optimization that adds complexity without measurable benefit.
-
-6. **Concurrency:** Thread safety is critical in RocksDB. Document synchronization assumptions clearly. Use appropriate memory ordering semantics. Consider potential race conditions and deadlocks.
-
-7. **Code Style:** Follow existing conventions for naming, formatting, and structure. Use `.clang-format` for consistent formatting. Prefer scoped enums (`enum class`) over unscoped enums.
-
-8. **Backwards Compatibility:** RocksDB maintains strong compatibility guarantees. Breaking changes require extensive justification. When deprecating features, provide migration guidance and maintain support across multiple releases.
-
-9. **Refactoring:** Reviewers appreciate refactoring that improves code readability and maintainability. Look for opportunities to deduplicate code and simplify complex logic.
-
-10. **Platform Compatibility:** Ensure changes work correctly on all supported platforms (Linux, Windows, macOS) and with all supported compilers (GCC, Clang, MSVC).

-## Important tips
-
-### Build system
-* There are 3 build system. Make, CMake, BUCK(meta internal).
-* When a new .cc file is added, update Makefile, CMakeLists.txt, src.mk, BUCK.
-* Don't manually edit BUCK file, after updating src.mk, run
-    /usr/local/bin/python3 buckifier/buckify_rocksdb.py to update it
-* Use make to build and run the test. CMake and BUCK are not used locally.
-* Use `make dbg` command to build all of the unit test in debug mode.
-* For -j in make command, use the number of CPU cores to decide it.
-
-### Unit Test
-* After all of the unit tests are added, review them and try to extract common
-    reusable utility functions to reduce code duplication due to copy past between
-    unit tests. This should be done every time unit test is updated.
-* Don't use sleep to wait for certain events to happen. This will cause test to
-    be flaky. Instead, use sync point to synchronize thread progress.
-* Cap unit test execution with 60 seconds timeout.
-* When there are multiple unit tests need to be executed, try to use
-    gtest_parallel.py if available. E.g.
-    python3 ${GTEST_PARALLEL}/gtest_parallel.py ./table_test
-* After writing a test, stress-test for flakiness:
-    ```bash
-    COERCE_CONTEXT_SWITCH=1 make {test_binary}
-    ./{test_binary} --gtest_filter="*YourTestName*" --gtest_repeat=5
-    ```
-
-### Unit test dedup guidelines
-* Extract helper functions for repeated patterns such as object
-    construction, round-trip (encode → decode → verify), and common
-    assertion sequences.
-* Use table-driven tests (struct array + loop) when multiple test cases
-    share the same logic but differ only in input/expected data.
-* Prefer randomized tests over exhaustive parameter permutations. Use
-    `Random` from `util/random.h` (not `std::mt19937`). Use a time-based
-    seed with `SCOPED_TRACE("seed=" + std::to_string(seed))` so failures
-    are reproducible.
-* Keep deterministic edge-case tests separate from randomized tests
-    (error paths, boundary conditions, format verification).
-* Methods only used in tests should be private with `friend class` +
-    `TEST_F` fixture wrappers. In wrappers, always fully qualify the
-    target method to avoid infinite recursion.
-
-### Adding new public API
-    Refer to claude_md/add_public_api.md
-
-### Adding new option
-    Refer to claude_md/add_option.md
-
-### Removing deprecated option
-    Refer to claude_md/remove_option.md
-
-### Metrics
-* When adding a new feature, evaluate whether there is opportunity to add
-    metrics. Try to avoid causing performance regression on hot path when adding
-    metrics.
-
-### Stress test
-* When adding a new feature, make sure stress test covers the new option.
-
-### Component docs
-* For component-level design notes and implementation walkthroughs, start with
-    `docs/components/index.md`.
-* Documentation under `docs/components/` is organized by subsystem in
-    `docs/components/<area>/`.
-* Each subsystem directory should have an `index.md` entry point plus focused
-    chapter files for deeper topics.
-
-### DB bench update
-* When adding a performance related feature, support it in db_bench
-
-### Adding release note
-* Release note should be kept short at high level for external user consumption.
-
-### Blog posts (docs/_posts)
-* Blog post authors must be defined in `docs/_data/authors.yml` to be displayed
-
-### Final verification of the change
-* Execute make clean to clean all of the changes.
-* Execute make check to build all of the changes and execute all of the tests.
-    Note that executing all of the tests could take multiple minutes.
-* Run `ASSERT_STATUS_CHECKED=1 make check` to verify all Status objects are
-    properly checked. This catches missing error handling that can lead to
-    silent data corruption.
-
-### Monitoring make check progress
-* Use `make check-progress` to get machine-parseable JSON progress while
-    `make check` is running. This is useful for Claude Code to monitor long
-    builds without timeout issues.
-* Run `make check` in background, then poll progress:
-    ```bash
-    make check &
-    # Poll periodically:
-    make check-progress
-    ```
-* The output shows current phase and progress:
-    ```json
-    {"status":"running","phase":"compiling","completed":300,"total":919,...}
-    {"status":"running","phase":"testing","completed":1500,"total":29962,"failed":0,"percent":5,...}
-    {"status":"completed","phase":"testing","completed":29962,"total":29962,"failed":0,"percent":100,...}
-    ```
-* Phases: `compiling` -> `linking` -> `generating` -> `testing` -> `completed`
-* Key fields: `status`, `phase`, `completed`, `total`, `failed`, `percent`
-* When tests fail, `failed_tests` array shows details (up to 10 failures):
-    ```json
-    {"status":"running",...,"failed":3,"failed_tests":[
-      {"test":"cache_test-CacheTest.Usage","exit_code":1,"signal":0,"output":"...test log..."},
-      {"test":"env_test-EnvTest.Open","exit_code":0,"signal":11,"output":"...Segmentation fault..."}
-    ]}
-    ```
-* `exit_code`: non-zero means test assertion failed
-* `signal`: non-zero means test was killed (e.g., 9=SIGKILL, 6=SIGABRT, 11=SIGSEGV)
-* `output`: last 50 lines of test log including error messages and stack traces
-
-### Executing benchmark using db_bench
-* Since the goal is to measure performance, we need to build a release binary
-    using `make clean && DEBUG_LEVEL=0 make db_bench`. If there is an engine
-    crash due to bug, we need to switch back to debug build. Make sure to run
-    `make clean` before running `make dbg`.
-
-### Formatting code
-* After making change, use `make format-auto` to auto-apply formatting without
-    interactive prompts (Claude Code friendly).

+# RocksDBLite
+
+RocksDBLite is a project focused on mobile use cases, which don't need a lot of fancy things we've built for server workloads and they are very sensitive to binary size. For that reason, we added a compile flag ROCKSDB_LITE that comments out a lot of the nonessential code and keeps the binary lean.
+
+Some examples of the features disabled by ROCKSDB_LITE:
+* compiled-in support for LDB tool
+* No backup engine
+* No support for replication (which we provide in form of TransactionalIterator)
+* No advanced monitoring tools
+* No special-purpose memtables that are highly optimized for specific use cases
+* No Transactions
+
+When adding a new big feature to RocksDB, please add ROCKSDB_LITE compile guard if:
+* Nobody from mobile really needs your feature,
+* Your feature is adding a lot of weight to the binary.
+
+Don't add ROCKSDB_LITE compile guard if:
+* It would introduce a lot of code complexity. Compile guards make code harder to read. It's a trade-off.
+* Your feature is not adding a lot of weight.
+
+If unsure, ask. :)

 //
-// Overall approach (see https://github.com/pdillinger/unique_id for
-// background):
+// Outputs come from bitwise-xor of the constituent pieces, low bits on left:
 //
-// First, we have three "structured" values, up to 64 bits each, that we
-// need to fit, without losses, into 128 bits. In practice, the values will
-// be small enough that they should fit. For example, applications generating
-// large SST files (large offsets) will naturally produce fewer files (small
-// file numbers). But we don't know ahead of time what bounds the values will
-// have.
-//
-// Second, we have unstructured inputs that enable distinct RocksDB processes
-// to pick a random point in space, likely very different from others. Xoring
-// the structured with the unstructured give us a cache key that is
-// structurally distinct between related keys (e.g. same file or same RocksDB
-// process) and distinct with high probability between unrelated keys.
-//
-// The problem of packing three structured values into the space for two is
-// complicated by the fact that we want to derive cache keys from SST unique
-// IDs, which have already combined structured and unstructured inputs in a
-// practically inseparable way. And we want a base cache key that works
-// with an offset of any size. So basically, we need to encode these three
-// structured values, each up to 64 bits, into 128 bits without knowing any
-// of their sizes. The DownwardInvolution() function gives us a mechanism to
-// accomplish this. (See its properties in math.h.) Specifically, for inputs
-// a, b, and c:
-//   lower64 = DownwardInvolution(a) ^ ReverseBits(b);
-//   upper64 = c ^ ReverseBits(a);
-// The 128-bit output is unique assuming there exist some i, j, and k
-// where a < 2**i, b < 2**j, c < 2**k, i <= 64, j <= 64, k <= 64, and
-// i + j + k <= 128. In other words, as long as there exist some bounds
-// that would allow us to pack the bits of a, b, and c into the output
-// if we know the bound, we can generate unique outputs without knowing
-// those bounds. To validate this claim, the inversion function (given
-// the bounds) has been implemented in CacheKeyDecoder in
-// db_block_cache_test.cc.
-//
-// With that in mind, the outputs in terms of the conceptual inputs look
-// like this, using bitwise-xor of the constituent pieces, low bits on left:

-// Some oddities or inconveniences of this layout are due to deriving

-// * Lower 64 of base_session_id occurs in both output words (ok but
-//   weird)
-// * The inclusion of db_id is bad for the conditions under which we
-//   can guarantee uniqueness, but could be useful in some cases with
-//   few small files per process, to make up for db session id only having
-//   ~103 bits of entropy.
+// Based on max_offset, a maximal number of bytes 0..3 is chosen for
+// including from lower bits of file_number in offset_etc64. The choice
+// is encoded in two bits of metadata going into session_etc64, though
+// the common case of 3 bytes is encoded as 0 so that session_etc64
+// is unmodified by file_number concerns in the common case.
 //
-// In fact, if DB ids were not involved, we would be guaranteed unique
-// cache keys for files generated in a single process until total bits for
-// biggest session_id_counter, orig_file_number, and offset_in_file
-// reach 128 bits.
+// There is nothing preventing "file number overflow & meta" from meeting
+// and overlapping with session_id_counter, but reaching such a case requires
+// an intractable combination of large file offsets (thus at least some large
+// files), large file numbers (thus large number of files generated), and
+// large number of session IDs generated in a single process. A trillion each
+// (2**40) of session ids, offsets, and file numbers comes to 120 bits.
+// With two bits of metadata and byte granularity, this is on the verge of
+// overlap, but even in the overlap case, it doesn't seem likely that
+// a file from billions of files or session ids ago will still be live
+// or cached.
 //
-// With the DB id limitation, we only have nice guaranteed unique cache
-// keys for files generated in a single process until biggest
-// session_id_counter and offset_in_file reach combined 64 bits. This
-// is quite good in practice because we can have millions of DB Opens
-// with terabyte size SST files, or billions of DB Opens with gigabyte
-// size SST files.
+// In fact, if our SST files are all < 4TB (see
+// BlockBasedTable::kMaxFileSizeStandardEncoding), then SST files generated
+// in a single process are guaranteed to have unique cache keys, unless/until
+// number session ids * max file number = 2**86, e.g. 1 trillion DB::Open in
+// a single process and 64 trillion files generated. Even at that point, to
+// see a collision we would need a miraculous re-synchronization of session
+// id and file number, along with a live file or stale cache entry from
+// trillions of files ago.

-// One of the considerations in the translation between existing SST unique

-// format_version. If we use a process-wide file counter instead of
-// session counter and file numbers, we only need to combine two 64-bit values
-// instead of three. But we don't want to track unique ID versions in the
-// manifest, so we want to keep the same translation layer between SST unique
-// IDs and base cache keys, even with updated SST unique IDs. If the new
-// unique IDs put the file counter where the orig_file_number was, and
