Each dropdown view sets its own axis type, and linear views reset the tick mode. - run_suite.sh gives each run one stamp: results/logs/<dataset>-<engine>[-docs<N>]-<stamp>.log and results/<dataset>/<engine>[-docs<N>]-<stamp>.json. Logs are never overwritten; the report checks the newest attempt per run. run.py takes --stamp; --docs=N is refused because the log name needs N.
…e query counts, aligned ladder table - run.py: each sweep setting warms up at the smallest k it measures and skips settings that measure none (an HNSW engine refusing ef < k no longer fails on text datasets, where k is always 100). - run.py: --k above the ground-truth width, unknown --stages and unknown --filters are refused before the build; abbreviated flags are refused (the log name needs the exact --docs); n_queries records the queries actually used. - report.py: section intros state the queries each run measured; the concurrency table uses the union of all engines' levels; the header lists every library version used across runs. - bench_data.py: anything but `fetch <name>` / `prepare <name>` prints the usage instead of preparing. - README: the ramp loop stops when a suite fails or is killed; chroma's serial memory peak includes its sweep reopens.
…stage, tabbed report
Engines now use each library's default index and search settings instead of a
shared M16/efC200 HNSW build. Every sweep starts with the library default ({}),
which is also the operating point for the latency and filter results.
- lancedb: create_index() default (IVF_PQ, refine_factor sweep) plus
lancedb-hnsw (IvfHnswSq defaults, ef sweep), replacing pure HnswSq
- --metric default|ip: library default distance or inner product (cosine for
sqlite-vec); run keys gain -ip; run_suite.sh skips engines whose default is
already inner product and the report reuses their default runs
- k defaults to 1,10,50,100; text datasets use k >= 10 and report recall@k
against the human labels
- searches return each library's default fields; zvec uses Query/queries
instead of the deprecated VectorQuery/vectors
- concurrency ladder, QPS and per-thread connections removed
- report: Charts and Tables tabs with a dataset picker; latency, build and
memory as bar charts with a measure dropdown; dropdowns ordered mean, p50,
p95, p99, p99.9; library default ringed on the tradeoff chart; tables sort on
header click, filter by words and bold the best value per column
- report: every y axis is linear from 0; dropdown views sharing a unit (mean, p50 ... p99.9; memory measures) keep one fixed range, so switching views never moves the axis. The trade-off chart keeps one recall range across k; the scaling chart plots docs linearly from 0. - report: the scaling chart's last point now comes from the full-corpus run of the same metric mode (ip lines previously stopped at the largest --docs run). - watchdog: WATCHDOG_MAX_RSS_GB overrides the 85%-of-RAM RSS cap.
…very chart - The trade-off chart's latency axis is log (latencies span 0.1 ms HNSW to 40+ ms exact scans at 100k), with one fixed range for every statistic and 1-2-5 ticks labelled in full (Plotly's own log ticks label 0.5 and 50 both as "5"). Every other axis stays linear from 0. - Each chart has a short description: what is plotted, which setting, which k, and what the dropdowns switch. The trade-off description notes that only the ringed library-default point matches the latency bars; the other points are the rest of the engine's search-setting sweep.
…recall target) For vector datasets, a bar chart and a table give each engine's latency at the cheapest setting of its sweep that reaches recall@k >= 0.95 and >= 0.99, per k: approximate engines tuned up, exact engines at their only setting, "not reached" when no setting gets there. The bar label names the setting. All views share one fixed linear axis; the chart opens at the largest k.
…F revision af9b886)
…cs on datasets without filters Subset ground truth is computed by a new 'bench_data.py subset-gt' step in its own process and loaded by run.py; computing it in run.py left up to 440 MB of freed temporaries in the footprint baseline, so subset index memory read low or negative. run_suite.sh creates the cache before --docs runs; run.py refuses a missing cache or one older than base.npy, and --docs outside 1..n_base-1. The filter-stage refusal now applies only to datasets with filter ground truth.
…outside the build timer Engine holds the shared adapter parts: metric from METRICS, library imports in __init__ (before the timer and the memory baseline), an untimed open() hook, a no-op set_search for exact engines and temp-dir cleanup in close(). Factories become functools.partial. Moss opens its session in open(): session() does authentication, a cloud index lookup and, for built-in models, model loading (0.7-1.0 s), none of which is index building. run.py records it as open_s. Search and non-Moss build code is unchanged.
… separate unmeasured pass Warm-up queries used to be the first 100 measured queries, which then ran faster in their measured pass (zvec 5-9%, chroma about 6% on cohere-100k). warmup_set() takes the queries after the measured ones when at least 100 exist, else 100 indexed docs (doc vectors or corpus texts); the result records which. Text example results come from their own unmeasured pass after the filter stage.
… one report page each - harness.py: shared load, open, build (timing and memory), warm-up, measured pass and result file; runners suite_defaults.py, suite_tuning.py, suite_filter.py write results/<suite>/<dataset>/ - engines: secondary search knob in engine.extra (LanceDB-HNSW refine_factor) apart from the primary sweep - run_suite.sh takes the suite and skips pairs that do not apply (harness.applies); NO_REPORT=1 skips the page rebuild - report_defaults.py, report_tuning.py (Pareto frontier of the primary knob only, secondary knob per engine), report_filter.py (one card per engine against its own unfiltered pass), report_scaling.py; report.py builds each page in its own process and writes the index - every bar carries its value; readable setting names; moss 1.16.1
…view; exact engines as dotted reference lines on the quality-vs-latency charts; BENCH_RESULTS for building pages from another results dir
…e reference lines overlap on the quality-vs-latency chart zvec's defaults and tuning builds differed by up to 0.0001 recall at k = 50 and 100 on cohere-100k and dbpedia-openai-1m, so it joins Chroma, DuckDB-VSS and LanceDB in the README and tuning-page disclosure. The Recall vs latency description now names exact engines whose mean latencies at a shown k are within 10% (dbpedia-openai-1m inner product: faiss-flat 27.16 ms, moss 26.56 ms at k = 100), since one dotted line hides the other.
…-1m index build The first measured passes after the ~55 s build ran 1.2-2.4x slower than the same setting measured later in the run (k = 10, library default metric: 0.320 ms vs 0.138 ms at ef 16, the default), so its default-settings latency and lowest Pareto point on that dataset are overstated. Documented in the README known behaviors and in the report's latency note.
RESULTS.md: what recall below 1.0 means for an application, key findings (default recall, the recurring cost of tuning, filtered search, in-memory vs on-disk storage, exact-search speed, hybrid text search) and an engine benefits/tradeoffs table. RESULTS-DETAIL.md: setup, per-engine numbers at 1M docs, recall drift with corpus size, persistence and rebuild cost, filtered search, SciFact, and limits. README links both and lists moss 1.16.1 (core 0.30.1).
…ns and max recall in the detail RESULTS.md: plain-language recall, high-level findings without per-engine numbers (tuning as a recurring cost, filtered search trading recall for speed, SciFact as the realistic text test, saving in-memory indexes, index growth), engine benefits/tradeoffs with Moss disk and cloud index storage and FAISS write_index(). RESULTS-DETAIL.md: incremental vs full build times at 10K, 100K, 250K docs and build cost per doc up to 1M, max recall where 0.99 is not reached, wording aligned with the summary. The MiniLM comments describe the non-Moss embedder without naming Moss's model.
Recall is described as the share of a query's best matches by embedding similarity that an engine returns, with a skipped match replaced by a weaker one (not an irrelevant one); approximate vs exact, filters, the SciFact embedding setup and slow exact engines are described without jargon.
…s a use-it-when column and an HNSW explainer The frontier traces were created with showlegend only for the default k, and the k dropdown reused those initial values, so any other k showed no legend. Hidden traces already stay out of the legend, so the per-k showlegend is dropped.
…t-when conditions per engine The use-it-when column names the conditions that make each engine fit a local application (RAM, build and insert cost, latency, corpus size, recall, filters, tuning). FAISS-flat's tradeoff says ids and metadata are the caller's to store, which does not conflict with saving the index.
…flat parity scoped to 1M docs; SI k for thousands
Memory and disk values are bytes / 2**20, so reports, docs and docstrings now say MiB/GiB; README download sizes re-measured with consistent units. RESULTS-DETAIL.md: 1M table at p95 with a tuning marker, search peak memory and N/A for unsaved in-memory indexes; one column per measure in the filter table; full SciFact table; best values bolded; numeric columns centered. RESULTS.md: R for recall in tables, Cohere dataset listed, filter and growth wording made precise.
…he cloud benchmark to benchmarks/cloud The cloud end-to-end latency benchmark (Moss vs Pinecone, Qdrant Cloud and ChromaDB, from main) returns under benchmarks/cloud/. The local benchmark's paths, stop patterns and lint commands now name benchmarks/local/, and its .gitignore also matches symlinked .venv, data and results. A short benchmarks/README.md links both; the root README's reproduce link points at benchmarks/cloud/.
- Equal-recall chart prefers the library default when it reaches the target within 5% of the fastest setting (a tuned row equal to the default, e.g. DuckDB-VSS ef 64 or Chroma ef 100, was shown as tuning). - Report pages fail with MIXED when the newest runs of one dataset differ in --queries or --k, so a smoke run cannot silently replace a full run. - DNFs of moss, zvec and qdrant-local also show in the inner-product view. - Metric note: identical ranking holds for exact search only; approximate indexes can differ in recall by metric (LanceDB IVF-PQ 0.66 l2 vs 0.53 ip). - RSS increase over the build is documented as including the memory-mapped dataset; FAISS-HNSW transient note names which runs the numbers come from. - README: quick start runs both metric modes (moss, qdrant-local and zvec only run with --metric default), Qdrant peak RSS in GiB from the current runs, current LanceDB and FAISS-flat figures, LanceDB nprobes not swept, WATCHDOG_MAX_RSS_GB and NO_REPORT documented.
…er the settings tried Adding a flat index in 100k chunks left freed growth buffers in the process footprint (+1.76 GiB for 400k x 1536, not returned by malloc pressure relief), overstating its index memory; HNSW keeps chunked adds. The results docs now give LanceDB's best recall as best over the settings tried (nprobes was not swept) and note that Moss's session setup is not timed.
Index memory 9.7 -> 5.7 GiB (the data size), build 1.3 -> 0.6 s, p95 at k = 10 25.0 ms (ip) and 47.9 ms (l2). Moss is now stated as within 7% of FAISS-flat at 1M (25.2 vs 23.6 ms mean) instead of matching it, and the limits note the re-run dates.
Every engine adapter loads documents in batches, so FAISS-flat goes back to 100k-row adds for a like-for-like comparison, and the docs return to the numbers of the original runs.
RESULTS.md gets an at-a-glance section (defaults: missed matches, p95 latency and included features; tuned recall vs latency on cohere-100k; SciFact quality vs latency). RESULTS-DETAIL.md places eight charts next to the tables they illustrate. Images are hosted as GitHub attachments; each has alt text with its key numbers.

Make fetch resume a partial download that has a committed checksum.
checksums.json is committed with entries for cohere-100k, dbpedia-openai-1m, hotpotqa-1m and scifact. A new user's first fetch can be interrupted, for example by the watchdog time limit on the 8.87 GiB dbpedia shards. In that case dst exists and key in sums is true. The curl -C - resume is then skipped. sha256(dst) differs from the recorded value, and fetch raises SystemExit("checksum mismatch ..."). Every later fetch fails the same way until the user deletes the file by hand. The module docstring says "resumable", and this path does not resume.
Skip the download only when the existing file matches the recorded digest. Otherwise resume it with curl, then verify it.

Fix the FaissEngine docstring so it matches the filter code.
The class docstring says filters use an IDSelectorBatch that is "built once per filter". _selector builds an IDSelectorBitmap inside each timed query. The README says the same as the code. The README and the code are correct, so update the docstring.

Close the engine in a finally block so failed runs clean up.
eng.close() runs only when measure(run) returns normally. suite_filter.measure raises SystemExit for an unknown --filters tag. Any engine error during a pass also skips close(). In those cases the temp directories of Chroma, LanceDB, zvec and sqlite-vec stay in $TMPDIR. These directories can be several GB at 1M docs. The Moss session also stays open and keeps consuming metered minutes. A finally block does not help when the watchdog sends SIGKILL. It does cover every exception raised in Python.

Replace the named lambdas with documented nested functions.
The rule for benchmarks/local/** requires a docstring on every function, including nested helpers. strip (Line 223) and order (Line 542) are named nested helpers. Each is written as a lambda with # noqa: E731, so neither can have a docstring. Write each one as a def with a one-line docstring. dnf_view (Line 255) repeats the same regex inline. It can call one shared helper instead.

Replace the nested strip and order lambdas with documented def helpers,
preserving their current behavior and regex logic while removing the E731
suppressions. Update dnf_view to reuse the shared strip helper instead of
duplicating the -ip regex inline.

Convert NaN memory values to None before you pass them to bars().
mem_gb() returns math.nan for "search peak" when the run has no peak_footprint_mb["search"]. The "Build and memory" table expects this case and prints "-" (Line 303). The chart does not handle it:
bars()treats onlyNoneas "no bar". A NaN value gets the labelf"{y:.4g}", which renders as "nan".yaxes()filters onlyNone. If the first run's value is NaN,max()returns NaN. The axis range is then[0, nan], because1.05 * nan or 1stays NaN.
Map NaN to None at this call site. With that change, the chart shows a gap, the same as the table.

Include datasets that have only DNF entries, as the other pages do.
The loop iterates sorted(set(runs)) only. Suppose every defaults run of a dataset failed, including the --docs runs. That dataset has no entry in runs, so the page leaves it out. Its --docs DNF lines are then lost without any message. report_defaults.py, report_filter.py and report_tuning.py all iterate set(runs) | {d for d, _, _ in dnfs} and show a "Did not finish" table. Use the same union here and read with runs.get(ds, {}).

Apply the bold rule the same way to zvec at 50k and 75k.
Line 32 says bold includes recall values "within 0.002" of the best. In this row, zvec's 0.998 is bold at 50k docs but not at 75k docs. Both values are 0.002 below 1.000. Bold the 75k value. If the rule is meant to exclude a difference of exactly 0.002, remove the bold from the 50k value instead.

Run subset-gt only for pairs that applies accepts.
The subset-gt loop runs before the harness.applies check. It also runs for every dataset in the list. Two cases fail:
- Text dataset. For example,
./run_suite.sh defaults "cohere-100k scifact" all --docs 25000. The scifact entry has nobase.npy, andbench_data.subset_gtraises "subset-gt applies to vector datasets only". The script then runsexit 1and runs no pairs. The README says such a pair "is skipped with its reason". - Wrong suite.
--docswithtuningorfilterfirst runs the heavy brute-force ground truth.appliesthen skips every pair.
Run the loop only for the defaults suite and only for vector datasets.
