From 22b0a7ab111f04f0d45d4ed69b5f2078e1b23f1d Mon Sep 17 00:00:00 2001 From: Stefan Steiner Date: Sat, 5 Sep 2026 10:40:03 -0700 Subject: [PATCH 01/22] fix(compile-check): stop false "not registered" errors in rust-analyzer compile_time_validation.rs showed two macro-error diagnostics in the editor -- "type `User` must `#[derive(Table)]` with `#[hyperdb(register)]`" and "table \"users\" is not registered" -- on a struct that plainly carries `#[derive(Table)] #[hyperdb(table = "users", register)]`. cargo check passes both with and without the compile-time feature, so these were editor-only. Registration is a process-global side effect of expanding derive(Table). Under cargo that is safe: rustc expands a crate's macros in one host process, and struct-level derives expand before function-body macros. rust-analyzer's proc-macro-srv is long-lived and expands lazily, out of order, and from cache, so a query_as! can be re-expanded in a process where no derive ever ran. That is why only two of the six macro call sites in the file were flagged -- the others still had valid cached expansions. Validation now distinguishes "this type is not registered" from "no derive has run here yet" by checking whether the registry is entirely empty, and skips rather than reporting an error it has no basis for. Genuine diagnostics are untouched: once anything is registered a miss is still a real miss, verified by injecting both failure modes into the example -- an unregistered struct still errors with StructNotRegistered, and a nonexistent column still errors with the UnknownColumn diagnostic. Also corrects the rustdoc, which asserted that within-file ordering "is not a concern". True for cargo, and precisely the assumption that broke here. One test needed adjusting rather than the fix being wrong. struct_not_registered_error asserted the diagnostic without registering anything first, so it only passed because some other test in the shared process happened to register earlier -- order is nondeterministic under parallel test execution. It now registers deliberately, which is also a more honest statement of what it tests. Verified stable over 10 consecutive runs. Deliberately not unit-testing the empty-registry skip: every test in that binary shares one process-global registry and they run in parallel, so any such test races between the emptiness check and the call under test. A first attempt at one flaked on run 3 of 5. Gates: fmt, clippy -D warnings (workspace and the out-of-workspace crate), doc, and cargo +1.88 all exit 0; compile-check 13 passed, derive tests pass; the example builds and runs; and rust-analyzer now reports no diagnostics on the file. --- hyperdb-api-derive/CHANGELOG.md | 13 +++++++ hyperdb-api-derive/src/lib.rs | 9 ++++- hyperdb-compile-check/src/registry.rs | 15 ++++++++ hyperdb-compile-check/src/validate.rs | 51 ++++++++++++++++++++++----- 4 files changed, 79 insertions(+), 9 deletions(-) diff --git a/hyperdb-api-derive/CHANGELOG.md b/hyperdb-api-derive/CHANGELOG.md index 459f91dd..b05b0a5e 100644 --- a/hyperdb-api-derive/CHANGELOG.md +++ b/hyperdb-api-derive/CHANGELOG.md @@ -7,6 +7,19 @@ and this project adheres to [Semantic Versioning](https://semver.org/). ## [Unreleased] +### Fixed + +- `query_as!` and `query_scalar!` no longer report false "not registered" + errors in rust-analyzer.

Either add one and extend the + list to nine, or state explicitly why it is exempt. + +**Verify:** `cargo test --workspace` count matches whatever the Makefile target +now claims. + +--- + +## Deferred: `hyperdb-api-node` (Tasks 10–13) + +Grouped so the N-API surface lands as one reviewable change. Ordered by weight. + +### Task 10: Guard the `expect()` at the N-API boundary + +`columnar.rs:107` is sound today — the bounds scan directly above makes the +`expect()` unreachable, verified by inspection: `LO..=HI` is inclusive, both +bounds are widening `i32 → i64` casts, and both passes iterate the same `v` +binding under one `&self` borrow with no interior mutability. + +The reason to act anyway: **napi 3.10 does not wrap `#[napi]` bodies in +`catch_unwind`** — no such call exists in its `src/`. A panic here unwinds into +V8's C++ frames, which is undefined behavior, not a JS exception. The +correctness rests entirely on the two passes staying coupled, and nothing +enforces that against a future edit. + +Add a `debug_assert!` in the narrowing pass, or move scan and map into one +function commented as a unit. Also add the missing `# Panics` section — +the workspace denies `missing_panics_doc` and this function has none (verified), +which pulls against commit `d7157c3`, where `protocol/types.rs` was +restructured specifically to avoid an `expect()` for that lint. + +### Task 11: Name the row and column in insert rejection errors + +A caller who buffers a million rows and calls `execute()` currently gets: + +```text +row encoding error: value 70000 does not fit the destination SMALLINT column (valid range -32768..=32767) +``` + +The whole batch fails with no way to locate the offending datum. This blunts +the Task 2.6 fix: the old behavior silently wrote a wrong number, and the new +behavior says a wrong number exists *somewhere* in your data. + +`encode_rows` already has both coordinates — `col_idx` from the `enumerate()` +at `inserter.rs:300`, and the row index one `.enumerate()` away on the `for row +in rows` loop at `:299`. Thread them into the `map_err` at `:305`. + +### Task 12: Add the missing `@throws` to `index.d.ts` write paths + +Both *read* getters were updated (`getInt32` at `:616`, `getInt32Column` at +`:230`). The three *write* paths were not — and by the change's own framing +those are the more serious half, since that is where corruption reached the +`.hyper` file. `RowInserter.addRow`, `addRows`, and `execute` carry no +`@throws`, so a TypeScript consumer gets no signal that a previously-succeeding +insert can now reject. + +Put it on `execute()` — that is where the error actually surfaces, not +`addRow()`. `addColumnar` has the same gap: a value routed through the +`int64Columns` bucket into an `INT` column now goes through `narrow_i32` +(`inserter.rs:392`) and throws, which its doc block at `:433` does not mention. + +### Task 13: Narrow the `cast_precision_loss` allow to its stated reason + +`columnar.rs:4-7` allows `clippy::cast_precision_loss` crate-wide with the +reason *"diagnostic metric output; bounded chunk sizes"*. That reason does not +describe what the annotation actually permits: it also covers +`get_float64_column`'s `x as f64` on an `Int64` column (`:131`) and +`result.rs:310`, which are data-path conversions losing precision above 2^53 on +real user values. + +The behavior is fine and matches `getInt64Column`'s documented caveat. Only the +justification is wrong. Narrow the allow to the specific diagnostic sites, or +widen the reason to name the data-path conversions honestly. + +--- + +## Not in scope: separate investigations + +- **macOS IPC is broken.** `BENCH_TRANSPORT=ipc` fails because `hyperd` never + creates the Unix socket the client dials + (`…/hyper-/domain/hyper`, ENOENT).

From 1cbdd4d61f8f60cfb2cf9fcd7ed8f0f5024d723f Mon Sep 17 00:00:00 2001 From: Stefan Steiner Date: Sat, 5 Sep 2026 11:11:58 -0700 Subject: [PATCH 03/22] fix(grpc)!: report Arrow failures in label lookups instead of a partial map get_table_labels and get_column_labels iterated record batches with `if let Ok(batch) = batch_result`, discarding decode failures. A corrupt batch mid-stream therefore produced a map covering only the batches that happened to decode, which a caller cannot distinguish from "this table defines no labels" -- the worst failure mode for metadata used to render UI. The same `if let` chain swallowed schema mismatches through its `downcast_ref` tuple, skipping the entire batch when a column was not TEXT. The `#[expect(clippy::manual_flatten)]` waivers that documented this as deliberate were removed during the edition-2024 let-chain sweep, which took the recorded intent with them. Reviewing it fresh, silence is not defensible here. Both now propagate. Safe to change: the only callers in the tree are in hyperdb-api-salesforce's example, which already uses unwrap_or_default(), and neither method is surfaced through hyperdb-api. Also fixes a latent panic the old code never guarded. RecordBatch::column(1) panics out of bounds, so a batch projecting one column would have aborted rather than errored; there is now a column-count check. The two functions had byte-identical parsing bodies, so the logic is extracted into parse_label_pairs and the bug is fixed once rather than twice, dropping about 50 lines of duplication. Parsing behavior is unchanged -- JSON displayName extraction, verbatim passthrough for plain descriptions, and NULL-row skipping are preserved, and now have unit tests that build real Arrow IPC streams: a truncated stream and a non-TEXT column must both be errors rather than partial maps, which is exactly what the old code returned. Gates: fmt and clippy -D warnings exit 0; cargo test --workspace is 1573 passed / 0 failed, up 5 from the new tests. --- hyperdb-api-core/CHANGELOG.md | 20 ++ .../src/client/grpc/authenticated_client.rs | 337 ++++++++++++------ 2 files changed, 253 insertions(+), 104 deletions(-) diff --git a/hyperdb-api-core/CHANGELOG.md b/hyperdb-api-core/CHANGELOG.md index cc97b042..14c0a40e 100644 --- a/hyperdb-api-core/CHANGELOG.md +++ b/hyperdb-api-core/CHANGELOG.md @@ -13,6 +13,26 @@ and this project adheres to [Semantic Versioning](https://semver.org/). ## [Unreleased] +### Fixed + +- **`AuthenticatedGrpcClient::get_table_labels` and `get_column_labels` now + report Arrow failures instead of returning a partial map.** Both iterated + record batches with `if let Ok(batch) = batch_result`, so a decode failure + mid-stream was discarded and the caller received a map covering only the + batches that happened to decode — indistinguishable from "this table defines + no labels", which is the worst failure mode for metadata used to render UI. + A schema mismatch was swallowed the same way, by the `downcast_ref` tuple in + the same `if let` chain. + + Both now return `Err`.

That package has not existed since the rename to hyperdb-bootstrap, so the suggestion failed outright: error: package(s) `hyperd-bootstrap` not found in workspace This is the first thing a new user sees when HYPERD_PATH is unset, which makes it the highest annoyance-per-minute defect in the post-RC list. The bootstrap binary's own "no hyperd installed" error had the same problem, suggesting `hyperd-bootstrap download` when the binary is hyperdb-bootstrap. Verified both directions rather than assuming: the old invocation errors as above, and the new one prints the CLI help listing the `download` subcommand. Also corrects the stale name in doc comments across both crates, a root Cargo.toml section comment, and one case that was a wrong *path* rather than just a name -- release.rs pointed at `hyperd-bootstrap/hyperd-version.toml` where the directory is `hyperdb-bootstrap/`. Deliberately left alone: the two User-Agent strings in scrape.rs. They are network-visible identifiers rather than documentation, and that path already carries Akamai bot-protection caveats, so changing them for cosmetic consistency is not worth any behavioral risk.

That claim was Linux-scoped: cfg-gated code is stripped before lints run and the clippy job only ran ubuntu-latest, so every #[cfg(windows)] block went unlinted. One survivor sat in process.rs's Named Pipe branch, where an is_some() guard wrapped an if-let on the same Option -- exactly the shape the sweep removed elsewhere. A Windows contributor running clippy by hand would have hit a hard failure. Adds windows-latest to the clippy job as a matrix. That leg is the one worth paying for: Windows carries a whole distinct Named Pipe transport path. macOS is deliberately left out, since it shares cfg(unix) with the Linux leg, so only #[cfg(target_os = "macos")] blocks remain unlinted -- a much smaller surface. The job comment records that reasoning, replacing the old note that claimed a single runner was enough. The Windows leg mirrors the test job: choco install protoc, per-OS cache keys, and the same ${{ github.workspace }}/.hyperd/current form for HYPERD_PATH, which that job already proves works there. hyperd is needed because --all-features starts an embedded instance in the proc-macro host. Verification of the code fix is CI's, not local: cross-compiling to x86_64-pc-windows-msvc fails here because ring's C build cannot find assert.h for that target, which is a cross-compile environment limit rather than anything about the change. Host fmt and clippy exit 0, and the edit is a mechanical removal of a redundant guard. --- .github/workflows/ci.yml | 28 ++++++++++++++++++++++------ hyperdb-api/src/process.rs | 6 ++---- 2 files changed, 24 insertions(+), 10 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 5b96f156..fda4d1e6 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -63,20 +63,36 @@ jobs: - run: cargo fmt --all --check clippy: - # Clippy lints are platform-independent, so a single runner is enough. - # If a lint ever diverges by target (rare), broaden the matrix. - name: clippy - runs-on: ubuntu-latest + # Most lints are platform-independent, but `cfg`-gated code is stripped + # before lints run, so a single runner leaves every `#[cfg(windows)]` block + # unlinted.

That crate declares its own [workspace] so it can build standalone, which means it cannot inherit the workspace lint tables and instead duplicates them -- and the commit that promoted the levels updated only the root. Nothing caught the drift because cargo clippy --workspace skips this crate entirely, so the "measured zero violations" evidence behind the promotion never covered it. Checked explicitly now: the crate satisfies both at deny with no changes needed, so the promotion is a no-op for its code and purely closes the inconsistency. Also documents why the duplication exists and how to lint the crate, since a forced-duplicate table with no enforcement is exactly what drifted.

Version-pinning does not help against a retagged or compromised release, so the archive's sha256 is now verified before it is unpacked. Upstream publishes no checksum file for protobuf releases, so the digest is computed from the asset and pinned in env: with the refresh command recorded next to it. Verified both directions locally: the pinned digest matches the real asset, and a tampered digest fails the check. The job had no concurrency group, unlike every other workflow in the repo. Since it builds a container and the whole workspace, successive pushes to a PR stacked multi-minute runs. Now serialized per ref, cancelling in-progress runs on pull_request only. Its cargo check --workspace could not see hyperdb-compile-check, which declares its own [workspace] -- yet release.yml publishes that crate. The one gate that proves "builds on Red Hat's system toolchain with no rustup" was therefore skipping a crate enterprise consumers can depend on. Now checked explicitly, matching what the msrv job already does. Also adds the long-missing `help` to the Makefile's .PHONY list, and confirms `make help` still works. Verification of the workflow itself is CI's: `make check-rhel` needs a container runtime that is not currently provisioned here.

It framed edition 2024 as something "a few of our transitive deps (rmcp, rmcp-macros, base64ct, clap_lex)" use. The entire workspace is edition 2024 as of 1.0.0, so the rust-analyzer incompatibility it warns about is now unavoidable rather than incidental. It also told contributors to run `rustup component add rust-analyzer` by hand. rust-toolchain.toml lists rust-analyzer in its components, so rustup provisions it with the toolchain -- commit 091327c claimed to obviate that instruction and the batched docs pass never followed through. The remaining step, pointing the extension at that binary via user settings, is kept because it is still needed and still deliberately uncommitted. Adds a note on the rust-analyzer registry quirk fixed in 22b0a7a, since an editor-only false error on code that cargo accepts is exactly the kind of thing a contributor would otherwise burn time on. --- AGENTS.md | 16 ++++++---------- 1 file changed, 6 insertions(+), 10 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index d6d8c046..1ae77c9d 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -147,25 +147,21 @@ HYPERD_PATH=~/dev/bin/hyperd cargo test -p hyperdb-mcp --test attach_tests ### Editor Setup (VS Code / Windsurf / Cursor) -A few of our transitive deps (`rmcp`, `rmcp-macros`, `base64ct`, `clap_lex`) use `edition = "2024"`.

Validation detects that and skips rather than reporting a false "not registered" error, so the editor should stay quiet on code that `cargo check` accepts. ### Common Commands From b877800b584a1256a6c78e6ea3fd41171d1c5faf Mon Sep 17 00:00:00 2001 From: Stefan Steiner Date: Sat, 5 Sep 2026 11:25:36 -0700 Subject: [PATCH 10/22] docs(bench): publish the 10M Rust table the comparison depends on MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The "Rust vs Node.js — 10M apples-to-apples" table quoted Rust figures at 10M rows, but only the 100M table was published, so not one Rust number in the comparison could be checked against a source. Worse, the 100M table sits directly above it, inviting the reader to assume the comparison came from there. Re-measured the Rust suite at 10M (median of 5 runs, same host and hyperd) and published it, then aligned the comparison rows to those exact medians. All eight Rust figures in the comparison now appear verbatim in the table above it, verified programmatically rather than by eye. Re-measuring corrected a review finding rather than confirming it. The aggregation cell reads ~1 K/s, which the review flagged as wrong on the grounds that the measured value is 199/s. That comparison was itself apples-to-oranges: 199/s is the 100M figure, while at 10M the same workload is 10 rows in 0.007s, or about 1.4 K/s. The cell was right; it was merely unverifiable. Left as-is. Also softens the first takeaway, which led with a x4 number and derived a two-significant-figure "2.4x speedup" from it -- directly contradicting the callout immediately above that warns those rows carry +/-20-61% spread and should be read as order-of-magnitude. --- docs/BENCHMARK_GUIDE.md | 34 +++++++++++++++++++++++++++++----- 1 file changed, 29 insertions(+), 5 deletions(-) diff --git a/docs/BENCHMARK_GUIDE.md b/docs/BENCHMARK_GUIDE.md index 542134f6..3a0f5b92 100644 --- a/docs/BENCHMARK_GUIDE.md +++ b/docs/BENCHMARK_GUIDE.md @@ -176,7 +176,7 @@ block from the suite's stdout. **Headline takeaways (Rust, macOS / M3 Max):** -- **Parallel reads are the standout** — `query.full_scan × 4` reaches **73 M rows/s / 1763 MB/s**, a 2.4× wall-clock speedup over the single-connection sync scan.

That gap produced defects twice in one session: duplicate changelog headings, untagged code fences, and a bulk auto-fix that corrupted 176 fences across 22 files by mistaking closing fences for opening ones. Adds reminder 3 with the invocation, an explanation of why there are three config files (markdownlint-cli2 does not read .markdownlintignore; the editor extension does), and the three traps that have actually bitten. It also warns that a pre-existing backlog exists, so a nonzero count is not automatically yours -- judge against `git show upstream/main:` rather than assuming, or you fix things that were never broken and miss what you introduced. Fixes the 4 of 10 current findings that this branch introduced, all MD024: each changelog already had a `### Fixed` or `### Added` further down the [Unreleased] section, and I appended a second one at the top. Merged into the existing sections, which also restores Keep a Changelog ordering (Changed before Fixed). Content verified intact after the merge. The remaining 6 are pre-existing and verified as such against upstream/main, including the 708-character KvStore line and the two hyperdb-mcp duplicates, which are byte-identical there. Writing the reminder promptly demonstrated the need for it: the first draft added 3 MD007 violations of its own, since AGENTS.md carries two nested-bullet styles and only the flush-left one lints clean. --- AGENTS.md | 38 +++++++++++++++++++++++++++++++++ hyperdb-api-core/CHANGELOG.md | 24 ++++++++++----------- hyperdb-api-derive/CHANGELOG.md | 20 ++++++++--------- hyperdb-api/CHANGELOG.md | 20 ++++++++--------- hyperdb-bootstrap/CHANGELOG.md | 12 +++++------ 5 files changed, 72 insertions(+), 42 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index c2132c2e..018baf76 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -496,3 +496,41 @@ All commit messages **must** follow the format `(): ` — appearing to "run." 2. **Never report a test/build as passing without seeing real output.** Check exit codes.

CI promotes it to an error via `-D warnings`. `HyperProcess::pipe_name` is `#[cfg(windows)]`, and `cfg`-gated code is stripped before lints run, so the ubuntu-only clippy job never compiled it and could not flag it. The newly added `clippy (windows-latest)` matrix leg compiles the Named Pipe transport path for the first time and surfaced it: error: this method could have a `#[must_use]` attribute --> hyperdb-api\src\process.rs:968:12 Annotated to match the neighbouring `#[cfg(unix)]` `socket_directory`, which already pairs the `cfg` attribute with `#[must_use]`. Audited every Windows-gated region in `hyperdb-api/src` (the only crate where the lint is `warn`) for further candidates: this was the sole one. The only other `cfg(windows)`-gated `fn` is `AsyncTransport::connect_named_pipe`, which cannot fire the lint — it is `pub(crate)` (not exported), `async`, and returns `Result`, and both `Future` and `Result` are already `#[must_use]`. Verified on the host: `cargo clippy --workspace --all-targets --all-features -- -D warnings` and `cargo fmt --all -- --check` both exit 0. The Windows target cannot be linted locally (`ring`'s C build cannot locate `assert.h` when cross-compiling to `x86_64-pc-windows-msvc`), so the windows-latest CI leg is the authority here. --- hyperdb-api/src/process.rs | 1 + 1 file changed, 1 insertion(+) diff --git a/hyperdb-api/src/process.rs b/hyperdb-api/src/process.rs index 2abdecd3..a3c1cb88 100644 --- a/hyperdb-api/src/process.rs +++ b/hyperdb-api/src/process.rs @@ -965,6 +965,7 @@ impl HyperProcess { /// /// Returns `None` if the process is using TCP. #[cfg(windows)] + #[must_use] pub fn pipe_name(&self) -> Option<&str> { self.pipe_name.as_deref() } From 6bb8a84b78fb2e706727ff9891fa73b753b55800 Mon Sep 17 00:00:00 2001 From: Stefan Steiner Date: Sat, 5 Sep 2026 12:20:57 -0700 Subject: [PATCH 15/22] fix(mcp): stop underscore-prefixing a parameter Windows actually uses MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Second finding from the new `clippy (windows-latest)` leg. The first one (`must_use_candidate` on `HyperProcess::pipe_name`) aborted compilation of `hyperdb-api`, so every crate downstream of it went unlinted — fixing that let the job reach `hyperdb-mcp` and report: error: used underscore-prefixed binding --> hyperdb-mcp\src\diagnostics.rs:1027:50 = note: `-D clippy::used-underscore-binding` implied by `-D warnings` `resolve_configured_hyperd` takes the configured HYPERD_PATH in both parsed and raw-text form. Only the `#[cfg(windows)]` `.exe` fallback consults the raw text, so off Windows the parameter is genuinely unused and the underscore kept rustc's `unused_variables` quiet. On Windows the underscore is a lie, which is exactly what `used_underscore_binding` detects. Dropping the underscore alone would break the ubuntu and macOS legs with `unused_variables` instead, so the name is now honest and the off-Windows discard is explicit — the same idiom already used at `watcher.rs:769` and `process.rs:998`. `items_after_statements` is `allow` workspace-wide, so the discard may precede the `HYPERD_EXE` consts.

Multi-connection (`× 4`) deltas are withheld per the tracker's methodology — 17–41% spread on this host, and the same workload read +23% at 100M but −20% at 10M in one session, so they carry no signal. The baseline leg was re-measured on the current API rather than taken from the recorded 2026-08-24 row, which was collected at `0.7.x`. It reproduces that row within ~1–5%, which is the evidence that the 0.7.x → 1.0.0-rc.1 API change did not move these numbers and that the delta above is the engine's. Docs - `docs/hyperd-release-benchmarks.md`: one insert row and one query row per engine, both at API `1.0.0-rc.1`. - `docs/BENCHMARK_GUIDE.md`: the macOS provenance now names the new pin, and the single-connection `AsyncArrowInserter` row is restated in both the 100M and 10M tables. The rows that only moved within run-to-run spread are carried forward and labelled as such — re-rolling them would have published a spurious −18% on `query.full_scan × 4`. Because the fastest Rust insert at 10M is now the single-connection async path rather than the `× 4` one, the Rust-vs-Node row flips from "0.9× (Node ahead)" to 1.2×; its Rust figures still appear verbatim in the 10M table above it.

Also fixes a correctness bug, not just a number: AGENTS.md credited `ArrowInserter` with 30M rows/sec, but the suite measures the async `AsyncArrowInserter`. The sync inserters measured 25.5 M rows/s and did not move with this engine, so the name was wrong and the figure now belongs to a different API than the one named. Every remaining claim names the exact API and the connection count it was measured at. Multi-connection (x 4) figures are dropped from prose rather than restated: they carry a 17-41% run-to-run spread on this hardware and read as deltas of both signs at different scales, so they are order-of-magnitude only and now live solely in the guide, which documents that spread. DEVELOPMENT.md's Rust-vs-C++ table is deliberately left unchanged and marked historical instead. The C++ side has not been re-measured, so refreshing only the Rust column would produce a cross-engine comparison that means nothing. --- AGENTS.md | 4 ++-- DEVELOPMENT.md | 48 ++++++++++++++++++++++++++++--------------- README.md | 4 ++-- hyperdb-api/README.md | 10 +++++++-- hyperdb-mcp/README.md | 2 +- 5 files changed, 45 insertions(+), 23 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index 018baf76..644ced28 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -30,7 +30,7 @@ This is a **pure-Rust implementation** of the Hyper database API, using the Post **Key characteristics:** - 100% pure Rust (no FFI, no C dependencies) -- High performance (25M rows/sec inserts, 31M rows/sec queries single-connection; 48M / 73M across 4 connections) +- High performance on a single connection (100M-row benchmark, Apple M3 Max): 68.9M rows/sec inserts via the async `AsyncArrowInserter`, 25.0M rows/sec via the sync `Inserter`, 31.1M rows/sec full-scan queries via the sync path.

Adds a step 5 adjacent to the "edit hyperd-version.toml" step, since the two files must move together: which keys to change and where, that the matrix hashes are the Java-zip sha256s the guard compares directly against the toml's values, that hyperd-slug uses the toml's platform names rather than npm's, and that the commented-out darwin-x64 entry is invisible to the guard but should be kept current so re-enabling those runners does not fail.
