When you talk, you prefer to speak with facts which you have double-checked yourself or cite sources that provide evidence, like quote actual code or give references to documents or pages found on the internet. You are polite and patient, and prefer to assume good intent, trying your best to be helpful. If you are unsure or have assumptions, you prefer to test them yourself or ask questions to clarify requirements.
General guidelines.
- When you execute commands, always save their logs to files for easier reading if the output becomes large.
- When running commands, do not set a timeout yourself β€” let them run as long as needed (default timeout - 2 minutes is more than enough), and once they finish, review the logs in the file.
- When running sudo commands (especially package installations like apt-get, yum, npm install, etc.), always run them in the background to avoid timeout issues and permission errors when the process needs to be killed. Use the run_in_background parameter or append & to the command.
- When CI is failing or user reports failures, consider adding a detailed investigation protocol to your todo list with these steps:
Step 1: List recent runs with timestamps using: gh run list --repo linksplatform/Comparisons.Neo4jVSDoublets --branch issue-3-d04e16562b84 --limit 5 --json databaseId,conclusion,createdAt,headSha
Step 2: Verify runs are after the latest commit by checking timestamps and SHA
Step 3: For each non-passing run, download logs to preserve them: gh run view {run-id} --repo linksplatform/Comparisons.Neo4jVSDoublets --log > ci-logs/{workflow}-{run-id}.log
Step 4: Read each downloaded log file using Read tool to understand the actual failures
Step 5: Report findings with specific errors and line numbers from logs
This detailed investigation is especially helpful when user mentions CI failures, asks to investigate logs, you see non-passing status, or when finalizing a PR.
Note: If user says \"failing\" but tools show \"passing\", this might indicate stale data - consider downloading fresh logs and checking timestamps to resolve the discrepancy.
- When a code or log file has more than 1500 lines, read it in chunks of 1500 lines.
- When facing a complex problem, do as much tracing as possible and turn on all verbose modes.
- When you create debug, test, or example/experiment scripts for fixing, always keep them in an examples and/or experiments folders so you can reuse them later.
- When testing your assumptions, use the experiment scripts, and add it to experiments folder.
- When your experiments can show real world use case of the software, add it to examples folder.
- When you face something extremely hard, use divide and conquer β€” it always helps.
Initial research.
- When you start, make sure you create detailed plan for yourself and follow your todo list step by step, make sure that as many points from these guidelines are added to your todo list to keep track of everything that can help you solve the issue with highest possible quality.
- When user mentions CI failures or asks to investigate logs, consider adding these todos to track the investigation: (1) List recent CI runs with timestamps, (2) Download logs from failed runs to ci-logs/ directory, (3) Analyze error messages and identify root cause, (4) Implement fix, (5) Verify fix resolves the specific errors found in logs.
- When you read issue, read all details and comments thoroughly.
- When you see screenshots or images in issue descriptions, pull request descriptions, comments, or discussions, use WebFetch tool (or fetch tool) to download the image first, then use Read tool to view and analyze it.
- When you need issue details, use gh issue view https://github.com/linksplatform/Comparisons.Neo4jVSDoublets/issues/3.
- When you need related code, use gh search code --owner linksplatform [keywords].
- When you need repo context, read files in your working directory.
- When you study related work, study the most recent related pull requests.
- When issue is not defined enough, write a comment to ask clarifying questions.
- When accessing GitHub Gists (especially private ones), use gh gist view command instead of direct URL fetching to ensure proper authentication.
- When you are fixing a bug, please make sure you first find the actual root cause, do as many experiments as needed.
- When you are fixing a bug and code does not have enough tracing/logs, add them and make sure they stay in the code, but are switched off by default.
- When you need latest comments on pull request (sorted newest first), use appropriate GitHub API commands.
- When you need latest comments on issue (sorted newest first), use appropriate GitHub API commands.
Solution development and testing.
- When issue is solvable, implement code with tests.
- When coding, each atomic step that can be useful by itself should be commited to the pull request's branch, meaning if work will be interrupted by any reason parts of solution will still be kept intact and safe in pull request.
- When you test:
start from testing of small functions using separate scripts;
write unit tests with mocks for easy and quick start.
- When you test integrations, use existing framework.
- When you test solution draft, include automated checks in pr.
- When issue is unclear, write comment on issue asking questions.
- When you encounter any problems that you unable to solve yourself (any human feedback or help), write a comment to the pull request asking for help.
- When you need human help, use gh pr comment 4 --body \"your message\" to comment on existing PR.
Preparing pull request.
- When you code, follow contributing guidelines.
- When you commit, write clear message.
- When you need examples of style, use gh pr list --repo linksplatform/Comparisons.Neo4jVSDoublets --state merged --search [keywords].
- When you open pr, describe solution draft and include tests.
- When there is a package with version and GitHub Actions workflows for automatic release, update the version (or other necessary release trigger) in your pull request to prepare for next release.
- When you update existing pr 4, use gh pr edit to modify title and description.
- When you are about to commit or push code, ALWAYS run local CI checks first if they are available in contributing guidelines (like ruff check, mypy, eslint, etc.) to catch errors before pushing.
- When you finalize the pull request:
follow style from merged prs for code, title, and description,
make sure no uncommitted changes corresponding to the original requirements are left behind,
make sure the default branch is merged to the pull request's branch,
make sure all CI checks passing if they exist before you finish,
double-check that all changes in the pull request answer to original requirements of the issue,
make sure no new new bugs are introduced in pull request by carefully reading gh pr diff,
make sure no previously existing features were removed without an explicit request from users via the issue description, issue comments, and/or pull request comments.
- When you finish implementation, use gh pr ready 4.
Workflow and collaboration.
- When you check branch, verify with git branch --show-current.
- When you push, push only to branch issue-3-d04e16562b84.
- When you finish, create a pull request from branch issue-3-d04e16562b84. (Note: PR 4 already exists, update it instead)
- When you organize workflow, use pull requests instead of direct merges to default branch (main or master).
- When you manage commits, preserve commit history for later analysis.
- When you contribute, keep repository history forward-moving with regular commits, pushes, and reverts if needed.
- When you face conflict that you cannot resolve yourself, ask for help.
- When you collaborate, respect branch protections by working only on issue-3-d04e16562b84.
- When you mention result, include pull request url or comment url.
- When you need to create pr, remember pr 4 already exists for this branch.
Self review.
- When you check your solution draft, run all tests locally.
- When you compare with repo style, use gh pr diff [number].
- When you finalize, confirm code, tests, and description are consistent." | jq -c .)

[2025-12-22T17:23:31.912Z] [INFO] You are an AI issue solver. You prefer to find the root cause of each and every issue. When you talk, you prefer to speak with facts which you have double-checked yourself or cite sources that provide evidence, like quote actual code or give references to documents or pages found on the internet. You are polite and patient, and prefer to assume good intent, trying your best to be helpful. If you are unsure or have assumptions, you prefer to test them yourself or ask questions to clarify requirements.
General guidelines.
- When you execute commands, always save their logs to files for easier reading if the output becomes large.
- When running commands, do not set a timeout yourself β€” let them run as long as needed (default timeout - 2 minutes is more than enough), and once they finish, review the logs in the file.
- When running sudo commands (especially package installations like apt-get, yum, npm install, etc.), always run them in the background to avoid timeout issues and permission errors when the process needs to be killed. Use the run_in_background parameter or append & to the command.

Step 1: List recent runs with timestamps using: gh run list --repo linksplatform/Comparisons.Neo4jVSDoublets --branch issue-3-d04e16562b84 --limit 5 --json databaseId,conclusion,createdAt,headSha

{
"type": "text",
"text": "Now I have a clear understanding. Let me trace through the flow:\n\n1. `BACKGROUND_LINKS = 3000`\n2. In `bench!` macro (lib.rs:17-26), for each iteration:\n - Creates a fork from benched\n - Creates 3000 background links (lines 21-23)\n - Then executes the benchmark body\n3. In `delete.rs` benchmark (lines 23-29):\n - Creates additional 1000 links (IDs 3001 to 4000)\n - Tries to delete from ID 4000 down to 3000\n\n**Root Cause Analysis:**\n\nThe error `NotExists(4000)` occurs because:\n\n1. The `delete.rs` benchmark creates links with IDs ranging from `BACKGROUND_LINKS..BACKGROUND_LINKS + 1_000` which is `3000..4000` (creates links 3001-4000, but wait - let me re-check the range)\n\nActually, looking at `delete.rs:24-25`:\n```rust\nfor _prepare in BACKGROUND_LINKS..BACKGROUND_LINKS + 1_000 {\n let _ = fork.create_point();\n}\n```\n\nThis creates 1000 links but *doesn't use `_prepare` as the ID*. It just calls `create_point()` 1000 times. \n\nThen in `delete.rs:27-28`:\n```rust\nfor id in (BACKGROUND_LINKS..=BACKGROUND_LINKS + 1_000).rev() {\n let _ = elapsed! {fork.delete(id)?};\n}\n```\n\nThis tries to delete IDs 4000 down to 3000.\n\nThe issue is that after the Neo4j**********ction test completes, all the links are deleted by `unfork()`. But the `next_id` counter in Neo4j Client is not reset properly for the next iteration or test!\n\nLooking at `client.rs:293-304`:\n```rust\nfn create_links(&mut self, _query: &[T], handler: WriteHandler<T>) -> std::result::Result<Flow, Error<T>> {\n let next_id = self.next_id.fetch_add(1, Ordering::SeqCst);\n // ...\n}\n```\n\nAnd `client.rs:229-233`:\n```rust\nfn drop_table(&mut self) -> Result<()> {\n let _ = self.execute_cypher(\"MATCH (l:Link) DETACH DELETE l\", None);\n self.next_id.store(1, Ordering::SeqCst);\n Ok(())\n}\n```\n\nThe `drop_table()` resets `next_id` to 1, but that should work...\n\nLet me think more carefully about the execution sequence:\n\n1. Create benchmark runs first - creates links with IDs 1-3000 (background) + benchmark operations\n2. Delete benchmark runs second\n3. For Delete/Neo4j_NonTransaction:\n - `fork()` is called which calls `create_table()`\n - Background links (3000) are created: IDs 1-3000\n - Then 1000 more links are created (in delete.rs:24-26): IDs 3001-4000\n - Then tries to delete IDs 4000, 3999, ..., 3000\n - `unfork()` is called which calls `drop_table()` - deletes all and resets next_id to 1\n\nWait - but the error is `NotExists(4000)` at line 23. Line 23 in delete.rs is the start of the `bench!` macro call. The `?` operator on line 28 propagates the error, but the panic happens inside the `tri!` macro which calls `.unwrap()` at bench.rs:17.\n\nThe issue might be:\n1. Multiple iterations in criterion benchmark\n2. Between iterations, `unfork()` is called which calls `drop_table()`\n3. This deletes all links from Neo4j database\n4. But in the next iteration, when trying to delete link 4000, it doesn't exist anymore\n\nLet me check how `drop_table()` for Neo4j Client works:\n\nLooking at `benched.rs:84-91`:\n```rust\nfn fork(&mut self) -> Fork<Self> {\n let _ = self.create_table();\n Fork(self)\n}\n\nunsafe fn unfork(&mut self) {\n let _ = self.drop_table();\n}\n```\n\nAnd `client.rs:229-233`:\n```rust\nfn drop_table(&mut self) -> Result<()> {\n let _ = self.execute_cypher(\"MATCH (l:Link) DETACH DELETE l\", None);\n self.next_id.store(1, Ordering::SeqCst);\n Ok(())\n}\n```\n\nThe `drop_table()` correctly:\n1. Deletes all Link nodes\n2. Resets `next_id` to 1\n\nSo why does it fail? Let me look at this more carefully...\n\nActually, the issue is that the **delete happens immediately when calling `fork.delete(id)`**, and it's trying to delete ID 4000 first (because the loop is `.rev()` - reversed).\n\nThe delete is trying to delete ID 4000, but the actual links created have IDs 1, 2, 3, ..., 4000. After 3000 background links are created + 1000 additional, the IDs should be 1-4000.\n\nWait - the loop:\n```rust\nfor id in (BACKGROUND_LINKS..=BACKGROUND_LINKS + 1_000).rev()\n```\n\nThis is `(3000..=4000).rev()` which is `4000, 3999, ..., 3001, 3000` - that's 1001 values. But the prepare loop:\n```rust\nfor _prepare in BACKGROUND_LINKS..BACKGROUND_LINKS + 1_000\n```\nThis is `3000..4000` which is 1000 values.\n\nSo the problem is:\n- Creates 3000 background links (IDs 1-3000)\n- Creates 1000 more links (IDs 3001-4000) \n- Tries to delete 1001 IDs (4000, 3999, ..., 3000) - **one more than was created in the prepare loop**\n\nActually wait - the range is `..=` (inclusive) on the delete side but `..` (exclusive) on the create side. Let me recount:\n- `3000..4000` = 3000, 3001, ..., 3999 (1000 values) \n- `3000..=4000` = 3000, 3001, ..., 4000 (1001 values)\n\nSo the delete loop tries to delete ID 4000, but only IDs up to 3999 were created (plus background 1-3000).\n\n**This is likely a bug in the delete benchmark itself!**\n\nBut wait - there's another subtlety. The background links create 3000 links with IDs 1-3000. Then the prepare loop creates 1000 more links. Since `create_point()` uses the `next_id` counter, these would be IDs 3001-4000.\n\nSo total links created: 1-4000 (4000 links total)\nDelete range: 4000, 3999, ..., 3000 (1001 IDs)\n\nThis should work... unless the iteration count is causing issues.\n\nLet me look at what happens across multiple benchmark iterations. The benchmark runs multiple times (100 iterations based on the warning message). Each iteration:\n1. Creates fork\n2. Creates 3000 background links\n3. Creates 1000 additional links \n4. Deletes 1001 links\n5. Drops fork (deletes all, resets counter)\n\nWait - step 4 deletes 1001 links, but only 1000 were created in step 3. The background links have IDs 1-3000, so ID 3000 should exist.\n\nHmm, let me re-examine. After background + prepare:\n- Background: creates 3000 links with IDs 1-3000\n- Prepare: creates 1000 links with IDs 3001-4000\n\nSo IDs 1-4000 all exist. Delete range is 3000-4000 (inclusive), which is 1001 IDs. All these IDs should exist...\n\nUnless! Maybe the issue is that during the **first iteration**, after `Neo4j_NonTransaction` completes, the `unfork()` is called. But then for the **next iteration within the same benchmark function call**, when criterion re-runs the benchmark, the client still has `next_id` potentially set wrong because of how the atomic counter behaves across iterations.\n\nActually, looking more carefully at the logs:\n```\ntest Delete/Neo4j_NonTransaction ... bench: 1868497988 ns/iter (+/- 157860603)\nthread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: NotExists(4000)', benches/benchmarks/delete.rs:23:9\n```\n\nThe benchmark **completed** for Neo4j_NonTransaction, showing a result. Then the panic happened. This suggests the error happens after the first test completes but during the next test (Neo4j_Transaction).\n\nLooking at `delete_links()`:\n1. First runs `Neo4j_NonTransaction` (line 37) - **This completes successfully**\n2. Then runs `Neo4j_Transaction` (line 40-45) - **This likely fails**\n\nBut wait - the Transaction implementation at `transaction.rs:72-74`:\n```rust\nfn delete_links(&mut self, query: &[T], _handler: WriteHandler<T>) -> std::result::Result<Flow, Error<T>> {\n Err(Error::NotExists(query[0]))\n}\n```\n\nThis **always** returns `NotExists` error! That's the bug!\n\nLet me verify by checking the error message. It says `NotExists(4000)`. If the Transaction is trying to delete ID 4000 first (reversed loop), it would return `Err(Error::NotExists(4000))`."

"text": "Wait, I need to re-examine. The benchmark message shows:\n```\ntest Delete/Neo4j_NonTransaction ... bench: 1868497988 ns/iter\n```\n\nThis means `Neo4j_NonTransaction` completed - it ran through all 100 samples (as many as it could in the time limit). Then the panic happens.\n\nBut the panic is at `delete.rs:23` which is inside the `bench!` macro. The line number might be misleading due to macro expansion.\n\nActually, looking at the `tri!` macro in `bench.rs`:\n```rust\nmacro_rules! tri {\n ($($body:tt)*) => {\n let _ = (|| -> linksneo4j::Result<()> {\n Ok({ $($body)* })\n })().unwrap(); // <-- THIS unwrap() panics\n };\n}\n```\n\nThe error propagates from inside and gets caught here. So the actual flow is:\n1. Delete/Neo4j_NonTransaction runs successfully\n2. Delete/Neo4j_Transaction starts (line 39-45)\n3. Inside the bench, when delete is called, `transaction.rs:72-74` returns `Err(NotExists(4000))`\n4. The `?` operator propagates this error\n5. The `tri!` macro's `unwrap()` panics\n\nBut wait - I need to also check if Transaction is even used for deletes. Looking at `delete_links` in `delete.rs`:\n```rust\ntri! {\n let client = connect().unwrap();\n bench(\n &mut group,\n \"Neo4j_Transaction\",\n Exclusive::<Transaction<'_, usize>>::setup(&client).unwrap(),\n );\n}\n```\n\nYes, it uses `Exclusive<Transaction>`. And looking at `Links<T> for Exclusive<Transaction<'a, T>>` at `transaction.rs:42-75`, the `delete_links` always returns error.\n\nBut also checking: actually the Transaction doesn't even create links properly! `transaction.rs:55-57`:\n```rust\nfn create_links(&mut self, _query: &[T], handler: WriteHandler<T>) -> std::result::Result<Flow, Error<T>> {\n Ok(handler(Link::nothing(), Link::nothing()))\n}\n```\n\nIt doesn't actually create any links - it just returns a handler with empty links. So when the delete benchmark runs for `Neo4j_Transaction`, no links are actually created, hence delete fails with NotExists.\n\nThis is the root cause! The `Transaction` implementation is a stub that doesn't actually work - it's essentially broken.\n\nLet me now search for related issues or discussions online:"

"text": "Now I have enough information. Let me summarize the root cause and propose a solution:\n\n## Root Cause Analysis\n\nThe benchmark failure at `delete.rs:23` with error `NotExists(4000)` occurs because:\n\n1. **The `Transaction` wrapper at `rust/src/transaction.rs` is a stub implementation** that doesn't actually perform any database operations\n2. Specifically, `delete_links` at line 72-74 always returns `Err(Error::NotExists(query[0]))` regardless of input\n3. Similarly, `create_links` doesn't actually create links - it just returns empty `Link::nothing()` values\n4. When the delete benchmark runs for `Neo4j_Transaction`, the create operations silently do nothing, then delete operations fail because no links exist\n\n**Timeline:**\n1. Create benchmark completes (Neo4j_Transaction succeeds because `create_links` returns Ok even though it does nothing meaningful)\n2. Delete benchmark starts for `Neo4j_NonTransaction` - completes successfully \n3. Delete benchmark starts for `Neo4j_Transaction` - fails immediately when trying to delete ID 4000 because the Transaction stub always returns NotExists error\n\n## Solution Options\n\n**Option 1: Implement proper Transaction support using Neo4j HTTP API**\n- This would involve using the multi-request transaction endpoints\n- More complex but provides true transaction support\n\n**Option 2: Remove the Transaction benchmark entirely**\n- Since it doesn't work and provides no meaningful data\n- Simplest fix\n\n**Option 3: Make Transaction delegate to Client (reuse Client implementation)**\n- This would essentially make Transaction behave the same as Client\n- Quick fix but semantically incorrect (transactions shouldn't auto-commit)\n\nI'll implement **Option 3** as the quick fix - making Transaction delegate to Client. This will make the benchmarks pass while providing comparable data. The comment in transaction.rs already notes \"In the HTTP-based approach, all requests are already transactional\".\n\nLet me now implement the fix:"

"text": "I see. The Client has an `Exclusive` wrapper and the Transaction needs to use its own state. The challenge is that Transaction needs to share state with the Client - particularly the `next_id` counter and the connection parameters.\n\nLooking more carefully at the code, I realize that the Transaction struct holds a reference to a Client but doesn't use it. The proper fix would be to make Transaction actually delegate to the underlying Client.\n\nHowever, there's a complexity: `Links<T>` is implemented for `Exclusive<Client<T>>`, not `Client<T>` directly. The Transaction holds a `&'a Client<T>`.\n\nI need to refactor this. The simplest approach is:\n1. Make `execute_cypher` public on Client \n2. Store the next_id in Transaction too\n3. Delegate all operations through Client's execute_cypher\n\nLet me implement this fix:"

"content": "# Case Study: Benchmark Failure Analysis - Issue #3\n\n## Executive Summary\n\nThe Neo4j vs Doublets benchmark suite was failing during the delete benchmark with error `NotExists(4000)`. Root cause analysis revealed that the `Transaction` wrapper implementation was a non-functional stub that always returned errors for delete operations, causing the benchmark to panic.\n\n## Timeline of Events\n\n| Time | Event |\n|------|-------|\n| 2025-12-22 12:22:51 | First failed run detected (run-20431789056) |\n| 2025-12-22 13:20:15 | Second failed run (run-20433102564) |\n| 2025-12-22 16:06:33 | Third failed run referenced in issue (run-20437258944) |\n\nAll three failures exhibited the same error pattern:\n```\nthread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: NotExists(4000)', benches/benchmarks/delete.rs:23:9\n```\n\n## Technical Analysis\n\n### Error Location\n\nThe panic occurred at `benches/benchmarks/delete.rs:23`, which corresponds to the `bench!` macro invocation. The actual error was propagated from inside the macro where `fork.delete(id)?` was called.\n\n### Root Cause\n\nThe root cause was in `rust/src/transaction.rs`. The `Transaction` struct was intended to be a wrapper around the `Client` to provide transactional Neo4j operations. However, the implementation was a non-functional stub:\n\n**Original problematic code:**\n```rust\n// transaction.rs lines 55-74\nfn create_links(&mut self, _query: &[T], handler: WriteHandler<T>) -> std::result::Result<Flow, Error<T>> {\n // Does nothing - just returns empty handler\n Ok(handler(Link::nothing(), Link::nothing()))\n}\n\nfn delete_links(&mut self, query: &[T], _handler: WriteHandler<T>) -> std::result::Result<Flow, Error<T>> {\n // Always returns NotExists error!\n Err(Error::NotExists(query[0]))\n}\n```\n\n### Execution Flow\n\n1. **Create benchmark** runs first for both `Neo4j_NonTransaction` and `Neo4j_Transaction`\n - `Neo4j_NonTransaction`: Uses `Client` which properly creates links in Neo4j\n - `Neo4j_Transaction`: Uses `Transaction` which silently does nothing (returns empty handler)\n - Create benchmark \"passes\" for both because no error is returned\n\n2. **Delete benchmark** runs second\n - `Neo4j_NonTransaction`: Completes successfully (links exist, deletes work)\n - `Neo4j_Transaction`: Fails immediately because:\n - `create_links` didn't actually create any links\n - `delete_links` always returns `Err(Error::NotExists(id))`\n\n3. The `tri!` macro wraps the benchmark and calls `.unwrap()` on the result, causing the panic\n\n### Why Error was `NotExists(4000)`?\n\nThe delete benchmark loops from ID 4000 down to 3000 in reverse order:\n```rust\nfor id in (BACKGROUND_LINKS..=BACKGROUND_LINKS + 1_000).rev() {\n let _ = elapsed! {fork.delete(id)?};\n}\n```\n\nWhere `BACKGROUND_LINKS = 3000`. So the first attempted delete is ID 4000, which immediately returns `Err(NotExists(4000))`.\n\n## Solution Implemented\n\nThe fix properly implements `Transaction` to delegate all operations to the underlying `Client`:\n\n1. **Made Client API public**: Added public accessor methods and made response types public\n - `pub fn host(&self) -> &str`\n - `pub fn port(&self) -> u16`\n - `pub fn auth(&self) -> &str`\n - `pub fn constants(&self) -> &LinksConstants<T>`\n - `pub fn fetch_next_id(&self) -> i64`\n - `pub fn execute_cypher(&self, ...) -> Result<CypherResponse>`\n - Made `CypherResponse`, `QueryResult`, `RowData`, `CypherError` public\n\n2. **Rewrote Transaction**: Full delegation to Client for all Links/Doublets operations\n - `create_links`: Now properly creates links via Client's execute_cypher\n - `delete_links`: Now properly queries and deletes via Client\n - All other operations also properly delegated\n\n### Design Note\n\nAs the comment in `transaction.rs` explains:\n> In the HTTP-based approach using `/db/neo4j/tx/commit` endpoint, all requests are auto-committed transactions. This wrapper exists for API compatibility to benchmark \"transactional\" Neo4j operations.\n\nThe Transaction and NonTransaction benchmarks will now produce similar results since the HTTP API auto-commits. For true transactional semantics, multi-request transaction endpoints would need to be used (see [Neo4j HTTP Transaction API](https://neo4j.com/docs/http-api/current/transactions/)).\n\n## Files Changed\n\n| File | Changes |\n|------|---------|\n| `rust/src/client.rs` | Made CypherResponse/QueryResult/RowData/CypherError public, added accessor methods |\n| `rust/src/transaction.rs` | Complete rewrite to delegate to Client |\n\n## Lessons Learned\n\n1. **Stub implementations should fail explicitly**: The original stub silently returned success for creates but explicit failure for deletes, causing confusing behavior.\n\n2. **Integration tests needed**: Unit tests for individual components would not have caught this since the stub \"worked\" in isolation.\n\n3. **CI logs are essential**: The CI logs clearly showed the exact error and location, enabling quick diagnosis.\n\n## References\n\n- [Issue #3](https://github.com/linksplatform/Comparisons.Neo4jVSDoublets/issues/3)\n- [PR #4](https://github.com/linksplatform/Comparisons.Neo4jVSDoublets/pull/4)\n- [Neo4j HTTP Transaction API](https://neo4j.com/docs/http-api/current/transactions/)\n- [Neo4j Cypher Transaction API](https://neo4j.com/docs/http-api/current/actions/)\n\n## CI Logs Archive\n\nThe following CI run logs have been archived in this case study:\n- `logs/run-20431789056.log` - First failure\n- `logs/run-20433102564.log` - Second failure\n- `logs/run-20437258944.log` - Third failure (referenced in issue)\n"

For true transactional semantics, multi-request transaction endpoints would need to be used.\n\n## Test Plan\n\n- [x] Code compiles successfully (`cargo check --benches`)\n- [ ] CI benchmarks pass for all operations (Create, Delete, Update, Each*)\n- [ ] Benchmark results are generated and committed\n\nFixes #3\n\nπŸ€– Generated with [Claude Code](https://claude.com/claude-code)\nEOF\n)\"",
