🛠 Asset Tracker
High-value, serialized gear — laptops, VFLs, OTDRs/testers, drills. Sign items out to a person for full accountability.
📊 Reports
Printable hand-offs, count sheets, labels, and exports.
📝 Foreman hand-off
One-pager for shift change: snapshot, open Requests, who has what signed out, today's activity — with checkboxes and pencil-edit space.
📋 Count sheets
One page per bay/level with system quantities, blank Counted boxes, and write-in rows. For a single shelf, use 🖨 Sheets inside that shelf.
🏷 Shelf labels
Barcode labels for shelves and bays — entire layout, a row, one shelf, or custom.
✍ Signed-out accountability
Everything currently out, grouped by tech — material and high-value assets, with return checkboxes.
📋 Simple report
One line per item with its total count — no separate line per shelf. The shelves it sits on are listed on the same row.
📦 Stock by location
Full on-hand listing grouped by shelf cell — the master picture of the laydown.
📤 Sign-out / pull sheets
Shelf contents with scannable barcodes plus blank “Taken to” and “By who” columns. Pull against it, then scan the codes back in to sign material out.
📥 Inventory & receiving
Everything on hand with its exact shelf location, plus everything received in the last 14 days with quantities and SOs.
🛠 Asset roster
All tracked high-value gear with status, holder, and due-back dates.
📊 Custom report builder
Filter by location, SO, category, manufacturer, or assignee and build exactly the report you need.
📁 Export reports folder (OneDrive)
Pick a folder and it writes 7 Excel files — daily activity, inventory, in stock, assets, Requests, stock by location, sign-outs. Share the folder on OneDrive so PMs and foremen can view them. Re-run anytime to refresh. (Chrome/Edge desktop.)
Keep the folder fresh on its own — re-writes the files on a timer while the app is open.
🔗 Part-number map
Your part-number map is the local link between shop numbers and your real product data. Run the one-time migration to stamp shop numbers and link inventory; export the map to share it; import a map someone sent you.
🔄 Device sync (shared file)
Pick one shared JSON file (put it on OneDrive and share it). Every device reads & writes it as the source of truth — changes merge both ways in the background, local storage stays your fast cache. Last edit wins per record; deletes propagate. The big catalog is left out by default so it stays quick.

❓ How to Format Your Request File
Your file or paste needs at minimum an item name/description and a quantity. Everything else helps but is optional. The app will try to auto-detect columns — put a header row at the top for best results.

💡 Tips: Copy directly from Excel — tabs are detected automatically. Column order doesn't matter as long as you have a header row. The app will highlight what it detected and show a preview before importing.

📁 Shared folder — sync across PCs
Share one database between computers: pick a folder that every PC opens (inside OneDrive or Dropbox). Everything lives in one file (silo-database.json) that merges in the background with deletes propagating; this replaces Supabase as the source of truth. Chrome/Edge on desktop only — iPad & the watch can’t pick a folder.

Not signed in
Your hankelsner.tech login is your SILO identity — it stamps every change in the chain of custody and decides what you can do. Manage the account (or switch user) from the bar at the top of the page.
🔗 Chain of custody
— events
Each event is SHA-256-linked to the one before it. Verify recomputes the chain; the root hash stands for the entire log — the tamper-evident custody record the server will trust.
🩺 Diagnostics
Scans for mismatches, duplicates, orphans, and accountability gaps. Self-heal corrects safe issues (types, whitespace, missing ids) automatically; risky ones are listed here with a one-tap fix.
Tap “scan now” to check your data.
⚙ Configuration Variables
Direct control over app internals. Also settable from the console via set <var> <value>.
More variables are available in the console — type set to list them.
📊 Click Telemetry
Most-used controls, ranked. Use this to place frequent actions within thumb reach.
🔌 External Command API
Drive the app from outside via a URL parameter — useful for handheld scanners that open links. …/laydown-ims.html?cmd=find:8220788 …?cmd=goto:inventory · …?cmd=add:8220788:5:D1-A
Colons become spaces. Any console command works. Open the console and type help for the full command set.
☁ Cloud backup — push clean configuration
Upload the entire database from this device to the cloud — inventory, history, requests, catalog, sales orders, asset tags, and the layout — and replace whatever is in the cloud. Other devices then pull this copy. This never runs automatically (so normal syncing can't overwrite anyone); use it only from the device that holds the correct, complete data.
Requires being signed in to your hankelsner.tech account with write access. Tip: export a JSON backup first.

universal barcode lookup
When enabled, a 🔍 "look up online" option appears on unknown barcodes. Auto-fills description & manufacturer so you can link it to a Part #. Most construction parts won't be in consumer databases — best for commercial/retail items.

Excel: multi-sheet workbook (Inventory, By Product, By SO, Catalog) — share via email or upload to Google Drive / OneDrive to collaborate live.

Tip: keep the file closed in Excel while working — reopen it to see the latest. Best on Chrome/Edge.

What this does: Creates product records in the catalog. Variant mode is useful when multiple vendors supply the same PN with different specs.
Two ways to bulk-attach part numbers to a SO:
Optionally add a tab + quantity after each PN. Descriptions are looked up from your product catalog automatically.
First paste your table in the Parts → Catalog tab and click "detect columns". Then come back here to attach those rows to a SO.

Define which part numbers are inside this box/bundle. When you scan this product during receiving, the bundle panel will offer to expand it into individual items.
