KERF & KEEP - CUSTOMER STARTER PACK
Prepared 2026-11-05; scoped native validation reconciled 2026-11-06 UTC.
This pack records synthetic samples and bounded evidence; browser/publication
certification is separate from these CSV and historical PDF records.

START HERE
Open index.html for the quick-start, downloads and troubleshooting.
The three pairs of CSVs use synthetic bundled example dimensions and finite
quantities. Back up existing work, then use a separate empty library for the
exercise. Sample dimensions are not instructions for a real cabinet or proof
that a piece of material exists, is sound, or is suitable for use.

WHAT IS INCLUDED
- csv/: parts and stock rows for the cabinet, inch-fraction and mixed-offcut
  fixtures. Measurements carry explicit unit suffixes. The native row format
  does not preserve original row IDs, saved plans, inventory history or settings.
- fixture-provenance.json: exact source hashes, row/quantity expectations,
  original row mappings and the settings that CSV cannot transport.
- native-csv-validation-cases.json: an 18-case plan, partially executed by the
  actual 12-group macOS run described below; remaining assertions stay explicit.
- samples/pdf/: six unchanged synthetic historical PDFs, in A4 and US Letter.
- sample-output-manifest.json: per-PDF hashes, original run provenance and limits.
- samples/provenance/: unchanged historical ledger and separate repeat-shop
  fixtures from which the PDF smoke case was constructed.
- package-inventory.json: file hashes and package scope.

KEEP THESE DISTINCTIONS
The six CSV files passed actual macOS NativeCSV read, preview, apply, export,
re-preview and re-apply checks against the original bundled fixture values.
Importing stock changes this job, not an existing recorded inventory library.
That library boundary remains source-derived; the run used disposable Project
values and did not execute a workspace library or UI. Append creates fresh identities
and does not merge quantities. Repeated imports can duplicate demand or stock
inputs. Review the preview, finite quantities and units before applying.

Save/autosave maintain the local working workspace. Back up workspace explicitly
exports a portable native copy; imported source files are not edited by local
autosave. CSV and PDF do not replace a native workspace backup. Earlier local
recovery/library copies and exported/provider copies are separate retained data.

The PDFs do not show solved outputs for these three CSV fixtures. They are
genuine retained R3 synthetic partial-plan test output from a separate hand-
derived repeat-shop case. The software commit is not a physical cut or customer
job. Their report date was deliberately fixed to 1970-01-01 by the test helper;
actual historical generation/check time is recorded in the manifest.

WHAT WAS CHECKED HERE
Actual macOS NativeCSV through the typed JavaScriptCore bridge passed 12 named
groups on 2026-11-06 at 01:10:29 UTC. Six groups compared exact dimensions,
quantities, material, thickness, grain, rotation, notes and stock kind with the
original fixtures, including export/re-import and explicit suffixes under the
opposite fallback unit. Selected controls covered wrong unsuffixed units,
whole-apply rejection of a partially invalid preview, unsupported id headers,
repeated append, and binding clearing on returned Project values. The full
18-case plan was not completed; literal allocated IDs and every diagnostic
location were not asserted. This was not a new 42-check bridge run.

The receipt is workspace evidence, not an included customer-pack member.

Original preparation also checked source alignment, package links and hashes.
Six PDF hashes and byte counts matched the retained historical ledger; PDF bytes
remain unchanged. The CSV run adds no iOS/native GUI, AppState/library persistence,
solver result, new PDF/printing or physical-stock evidence. Browser usability
and public download delivery are separate evidence, not certified by these
native row-exchange and historical PDF records.

No new price, availability, sales, support-response or future-delivery promise
is added by this pack. Root retains publication and release decisions.
