reproducible evidence log for the 2026-07-21--22 +performance audit.

Rejected candidates remain +here as evidence, but their production changes were rolled back. + +Result labels have six meanings: + +- `accepted`: the measured candidate passed correctness and resource gates. +- `rejected`: the candidate regressed a gate or weakened semantics; production + is unchanged. +- `pending_gate`: evidence is incomplete or a measured resource regression has + not been explicitly authorized; this is not an acceptance decision. +- `pending_representative_gate`: the benchmark population may not represent the + production cost distribution closely enough to authorize a tradeoff. +- `pending_explicit_user_tradeoff`: the representative gate is complete, but a + measured resource regression still needs explicit authorization or rollback. +- `accepted_by_explicit_user_tradeoff`: not Pareto-superior, but the user + explicitly chose the documented resource tradeoff after seeing both costs. + +Heap/RSS figures from in-process Node runs are indicative.

The +isolated representative A/B/C rerun below supersedes that exploratory result: +the compound candidate failed the no-regression gate and is absent from +production. + +## Frontend upload algorithms + +`frontend-upload-algorithms.mjs` isolates three algorithms: queue drain, +aggregate progress, and the proposed >10k whole-file dedup batching. It +alternates A/B order, accumulates tiny cases above timer resolution, forces GC +when available, and validates checksums/progress/protocol counts. + +Run the general harness from the repository root: + + node --expose-gc tools/perf-audit/frontend-upload-algorithms.mjs \ + --warmup 3 \ + --samples 15 \ + --queue-counts 64,256,1024,10000,50000 \ + --progress-cases 1:100,10:500,100:5000,1000:10000,10000:5000 \ + --hash-counts 1000,10000,10001,25000 \ + --output /tmp/oxicloud-frontend-upload.json + +The accepted progress implementation maintains the aggregate sum with +`new_fraction - old_fraction`; restart-to-zero and finalization are covered by +the frontend unit test. The preliminary common run improved every median but +had a noisy one-file p95 regression (2.136 -> 11.240 ms per 1,000-run block, +equivalent to a 2.136 -> 11.240 us/run block average, not a per-event p95), so +it is evidence-only. The +subsequent 41-sample focused gate improved both the normalized one-file median +(0.797 -> 0.289 us/run) and block p95 (14.158 -> 6.338 ms per 1,000 runs, +equivalent to a 14.158 -> 6.338 us/run block average) with identical output. +`progress-common-node26-macos-arm64.json` and +`progress-one-file-repeat-node26-macos-arm64.json` retain both sets of samples. + +### Delta-worker queue memory gate + +The in-process queue microbenchmark favored the cursor but was biased because +`Array.shift()` ran long enough for V8 to collect while the cursor finished +before the next GC. `queue-memory-gate.mjs` therefore runs every sample in a +fresh process, keeps the permanent ordered chunk table alive, and measures +wall time, max RSS, post-GC retained RSS, and heap for prefilled, +producer-ahead, and balanced shapes. + + node --expose-gc tools/perf-audit/queue-memory-gate.mjs \ + --count 100000 \ + --samples 5 \ + --output tools/perf-audit/results/queue-memory-process-node26-macos-arm64.json + +Production uses `cursor-clear-4096`.

The +queue result JSON marks it +`accepted_by_explicit_user_tradeoff` and retains the rejected thresholds, +`splice`, `slice`, no-clear, and array-reset variants. + +### Rejected whole-file dedup batching + +The microbenchmark correctly showed that one >10k request is rejected while +bounded requests recover owned hashes. That is functional evidence, not an +acceptance result: the rejected control returns no hashes and does less work. +The decisive loopback workflow includes every dedup, by-hash, and content +request at production upload concurrency: + + node --expose-gc tools/perf-audit/frontend-dedup-workflow.mjs \ + --samples 3 \ + --bytes-per-file 4096 \ + --output tools/perf-audit/results/frontend-dedup-workflow-node26-macos-arm64.json + +At 10,001 all-miss files, batching was 10.2% slower and increased median peak +heap/RSS. At 50% hits it saved 50.005% of content bytes and was 1.051x faster, +but roughly doubled peak heap and added about 27.9 MiB RSS. Backend SQL for the +two accepted ownership queries is not modeled, making the candidate optimistic. +The feature was rejected and reverted. The four `dedup-*` JSON files remain +labelled evidence-only so their invalid-control speedups cannot be mistaken for +production acceptance. + +## Admin user listing + +The accepted compact response fetches only fields rendered by the table; +full-detail API clients keep the previous shape unless `summary=true` is sent. +It avoids detoasting/transporting avatars and preferences.

Its 117.93x timing is the `psql` query/row-transfer/client-decode +gate, not an end-to-end HTTP claim; it excludes Serde and the service-layer +authorization check. The first index fixture has 500,000 users with 100-way +timestamp ties and checks exact order equivalence, first/deep pages, index +bytes, and 10,000-row insert cost. It is not an acceptance result: the +ties deliberately stress incremental sorting, but they also let PostgreSQL +compress the one-column B-tree into posting lists. Its 3.45 MB size and +0.596 +us per inserted user understated a normal mostly-unique registration workload. + +The decisive component harness includes the full historical SQL/DTO/Serde path +and the candidate's hot Moka flags lookup, system-admin policy check, compact +SQL/DTO, count query, and Serde. It excludes common router/JWT/socket work and +deliberately omits the old handler's intermediate `serde_json::Value` +materialization, making the historical baseline optimistic. It is therefore a +conservative component-path gate rather than a whole HTTP-stack claim. On the +minimal profile, 31 interleaved samples improved median latency 1.296 -> 0.966 +ms (1.341x), JSON fell 43,759 -> 28,726 bytes (-34.35%), and three fresh +processes saved 114,688 bytes (112 KiB) median max RSS. With 512 KiB avatars and +8 KiB preferences, median latency improved 1,141.422 -> 0.966 ms, JSON fell +53,306,743 -> 28,726 bytes (-99.946%), and median max RSS fell by 138,625,024 +bytes (132.20 MiB). Exact rendered fields, ordering, and counts matched. + +The follow-up ran three independent rollback-only transactions, for 15 A/B +samples per shape, with the UUID primary-key index present on both sides. At +500,000 unique timestamps the index was 11,255,808 bytes (3.263x the prior +disclosure), first-page/deep-page reads improved 266.13x/24.21x, and 10,000-row +insert medians imply +0.680 us per user. Ten-user bursts used 4,751,360 bytes, +improved reads 321.57x/18.29x, and added +0.582 us per user. Every initial/final +order and row-count check passed in all three transactions. Because the +representative unique-key disk cost is materially larger than the original +disclosure, the first authorization was invalidated. After seeing the corrected +11,255,808-byte/+0.680-us unique cost and the 4,751,360-byte/+0.582-us burst10 +cost, the user explicitly reauthorized the timestamp-only index. It is therefore +`accepted_by_explicit_user_tradeoff`. + +The later isolated A/B/C gate retained 15 samples per shape. Versus that +accepted narrow index, the compound index regressed the common unique-timestamp +first page 0.186 -> 0.198 ms (+6.45%), enlarged the unique index 11,255,808 -> +20,275,200 bytes (+80.13%), and enlarged the ten-user-burst index 4,751,360 -> +20,324,352 bytes (+327.76%). It did accelerate deep pages 1.63x-2.30x, but burst +insert medians regressed 44.475 -> 48.921 ms per 10,000 rows (+0.445 us/user). +It therefore failed the no-regression gate and was rejected. Raw A/B and A/B/C +samples are in `admin-user-index-representative-postgres18-macos-arm64.json`; +component-path samples are in +`admin-user-listing-e2e-postgres18-macos-arm64.json`. Production keeps one +narrow online `CREATE INDEX CONCURRENTLY` statement. + +## Local blob durability preparation + +`local_sync_grouping.rs` A/Bs only the CPU/allocation preparation around the +unchanged fsync work: moving owned `PathBuf`s into task groups instead of +cloning, and a fixed exact-case prefix bitmap instead of sort/dedup of parent +paths. It checks ordered file-path equivalence plus case-sensitive `af`/`aF` +directory equivalence before timing. + + rustc --edition 2024 -O tools/perf-audit/local_sync_grouping.rs -o /tmp/local-sync-grouping + /tmp/local-sync-grouping + +The zero-path gate caught avoidable candidate setup and led to a production +fast return. In 11 fresh processes, each running 31 alternating samples of +100,000 repetitions, it won 10/11 times; the median of process medians improved +25.607 -> 22.946 ns (1.116x). All measured non-empty sizes from 1 to 100,000 +paths also improved. The bitmap is fixed at 22x22 slots so uppercase and +lowercase directory names remain distinct on case-sensitive filesystems. Raw +process medians are in `backend-audit-macos-arm64.json`. + +## Cached blob bounded ranges + +`CachedBlobBackend` was the only backend treating `end` as inclusive even +though the port, Local, S3, Azure, encrypted, CDC, RAM-cache, and HTTP adapter +paths all use `[start, end)`. It consequently read one surplus byte on every +bounded cold-after-fill or hot-cache range. The production fix changes only the +two cached-file limits to `end.saturating_sub(start)` and adds a cold/hot +regression test, including the empty `[3,3)` range. + +Run the focused semantic test and standalone hot-file A/B: + + cargo test --lib \ + cached_blob_backend::tests::range_end_is_exclusive_on_cold_and_hot_cache_reads + cargo run --release --manifest-path tools/perf-audit/Cargo.toml \ + --bin cached_range_ab + +For 10,000 interleaved `[1,3)` reads, the historical path returned 30,000 +bytes versus the correct 20,000 (-33.333% for this two-byte fixture). Median +latency stayed 8.459 us; p95 improved from 28.292 to 26.917 us (-4.86%). The +cold fill remained exactly one origin GET/six bytes. The fixed Local/cached +length vectors both equal `[1,2,0,4]`; the historical cached vector was +`[2,3,1,4]`. Exact evidence is in +`cached_range_exclusive_2026-07-22.json`. + +## Manifest garbage collection + +`gc_manifest_batch.rs` compares the historical serial update per deleted +manifest with several measured candidates. Production keeps the accepted +hybrid: the dominant empty sweep uses the original simple `DELETE RETURNING`, +one returned manifest uses the original serial update, and batches of two or +more aggregate exact distinct-per-manifest decrements in an owned `HashMap` +before one `UPDATE FROM unnest`. + +The crossover was positive at two manifests. At 500, statements fell 502 -> 3 +and median latency 1,456.096 -> 24.255 ms (60.03x); at 1,000, 1,003 -> 5 and +3,163.190 -> 61.829 ms (51.16x). Five fresh processes measured no RSS change at +two, +720 KiB at 500, and +1,008 KiB at 1,000. The user explicitly accepted +that bounded memory tradeoff, so the result is +`accepted_by_explicit_user_tradeoff`. + +The atomic all-in-one CTE was rejected because an all-live sweep regressed +15.59%-44.84%. Borrowed SQLx binds saved memory but regressed large-batch +latency; sorted/RLE scratch was not Pareto either.

The accepted implementation keeps the exact serial +path through four valid occurrences.

The 262,144-row page used 60,833,792 bytes +(-42.64%) and took 1,928.731 ms (+199.31%, 2.99x). Both candidates therefore +failed the no-latency-regression gate and production remains unchanged.

The +semantic regression rejected the candidate and production was reverted. See +`migration-verify-sampling-postgres18-macos-arm64.json`. + +## Rejected storage candidates + +`rejected_storage_candidates_2026-07-21.json` records two fully rolled-back +experiments. Their Rust files are archived diagnostic source snapshots rather +than registered binaries in the standalone perf Cargo package. + +### Loose-chunk prefilter + +`rejected_delta_loose_hit_probe.rs` counted physical object-store PUTs/bytes for +400 x 256 KiB frames. The browser protocol already negotiates missing hashes, +so all-miss is the normal receive path. A DB prefilter would add queries and up +to 8 MiB request buffering there. More importantly, a metadata row does not +prove the backend object exists: skipping PUT based only on PostgreSQL would +remove the current self-healing overwrite for missing objects. No candidate +showed a Pareto win across miss latency, RAM, remote bytes, and repair semantics. + +### Identical-overwrite refcount CTE + +`rejected_refcount_overwrite_probe.rs` exercised the public write port on +legacy, CDC-manifest, different-hash, delete/GC, missing-file, SQL-error, and +lifecycle-hook fixtures. The proposed CTE fixed unambiguous same-representation +cases, but `storage.files` stores only a hash. When legacy `storage.blobs` and a +new `storage.chunk_manifests` row coexist under that hash, the swap cannot know +which representation owns the displaced reference. It can decrement live CDC +state or preserve a shadowed legacy reference/bytes. Timing samples also had +enough container jitter that no non-regression claim was possible.
