Veloce Workbench. Local-first desks in this browser.

Use the online tools. Files stay in the tab — we do not ship a public zip of this pack. Offline VERIFY from two JSON files, wait-graph ghost lock, SHOW BASELINE, OGC cursor-bind, Tachyon ISAM Open analog, latency SLO, hash index, SSTable tombstone, graph walk, Excel → IN clause, CSV doctor, desk hop under Gmail’s 25 MB cap. This is not Workgroup Standard, not Enterprise, and not mixed into Stripe checkout. Engine installers stay on Downloads after you buy or start the 30-day trial.

Open Workbench

certifiedClaim = false. Journal does not replace Raft. PII masker is not HIPAA. TCP 1583 is leftover EXTERNAL. Files chosen here are not sent to veloce.tuce.app.

Offline VERIFY

AWS ended QLDB. Aurora kept the table and dropped the proof. Paste two files. Pass or fail in this tab.

Recomputes a merkle-v0 inclusion path in this tab from two JSON files. Not RFC 6962. Does not fetch a Blob.

License trap meter

The SAM letter is priced in core packs you already forgot. See the floor before procurement answers.

Dated 2026-08-19 SQL Server list. Worksheet, not a quote, not booked ARR.

Systems Desk

Watch p99 move when ρ crosses 0.80. Live DES plus Erlang-C twin. Modeled load, not this tab’s RPS.

Queueing analog in the browser. 15 blueprints, 24 runnable chaos rows, AWS us-east-1 list worksheet. analog ≠ native. Not a Workgroup license.

Wait graph

The session looks idle. The lock is still there. Cancel will not save the ALTER.

Idle-in-xact ACCESS SHARE vs ACCESS EXCLUSIVE FIFO. jumpQueue=false. Cancel of a finished SELECT is a no-op. Terminate drains. analog ≠ native. Not pg_locks.

SHOW BASELINE

The register names what is HAVE and what is leftover before anyone stamps LIVE.

Pack 15 analog leftover. Inventory 94, SHIP empty CRITICAL fails, SHOW GEO LAW / SHOW LEFTOVER, companion PROPOSED. Host kernel stays 2.73.13 W5. Not a Community SKU.

OGC items analog

The next link cannot hop collections. The token stays off the URL.

RFC 7946 dump, no crs. CSV+WKT sibling. v2 cursor TTL 900s + collection bind. SET GEO PACK is a rebuild recipe. analog ≠ native. Not a certified OGC server. RISK-10 OPEN.

Tachyon ISAM Open analog

GetEqual before Open is status 3. That is the teaching, not a drop-in.

Latency report

The p99 you remember is the stall the closed loop threw away.

p50/p90/p99/mean, SLO verdict, error-budget remaining, coordinated-omission closed vs open. k6/Gatling letter leftover EXTERNAL.

Hash index

A hash index is not a B-tree. Range is the wrong question.

Append-only log + offset map + replay. Range queries refuse. analog ≠ native hash.

SSTable

Deletes are records. Compact the wrong way and the row comes back.

Sparse index, Bloom skip (false-negative forbidden), k-way merge, tombstone resurrection fail-closed, pending-compaction-bytes.

Graph walk

The walk already named how many queries one request spent.

Reachability, shortest path, overlapping tenures, queries-per-request. OWL leftover EXTERNAL.

IN-clause packager

Excel gave you 400 emails. The WHERE clause is one click, not an afternoon of quotes.

Escape, unique, lower, 20k cap. Does not run the query.

JSON ↔ CSV flatten

The API gave you nested objects. Finance wants a sheet. Keep the path names.

Dotted keys, array policy, explode, 2 MB cap. Local.

CSV doctor

Excel opened it wrong. We will name the BOM, the semicolon, and the ragged row.

RFC 4180 analog, offline.

Will this attach?

Gmail stopped you at 25 MB. See the MIME math before you split.

Raw MB vs ×4/3 on the wire. Gmail 25 is ~18 raw.

Desk hop

Split the dump. Hash the parts. The other laptop puts them back. We never hold the file.

Path A parts + SHA-256 manifest. Path B WebRTC, public STUN, no TURN. No locker.

Excel serial date

Finance dumps store days since 1899. Decode to ISO in this tab.

Serial → ISO. Local. Not Excel.

See BOM, ragged rows, and quoted newlines before you \copy.

Preflight only. Does not run COPY.

COUNT(*) vs COUNT(col)

The sheet said NULL. The database heard a word. Stop arguing with COUNT.

Per-column why the two counts disagree.

Paste the query. Get it back readable. Leave with the tab bookmarked.

Client-side indent + SHOW verbs. No account.
