Context

The PR re-takes the vendored entitlement-key reader from upstream tag 6.1.0.

• Why: the drift check fails on develop. Every file still matches the pinned tag 5.1.1, and the only problem is that upstream has released 5.2.0, 6.0.0 and 6.1.0 since.
• What changed (in hyperformula/src/license/handsontable-license-key-parser/):
  • README.md: upstream's file at 6.1.0. It is the only file in upstream's vendor/entitlement-key-reader/ that changed between 5.1.1 and 6.1.0.
  • upstream.json: the pin names tag 6.1.0 and its commit.
  • PROVENANCE.md: the table names the new tag.
• Result: the copy is upstream's directory at 6.1.0, byte for byte, with the one declared TypeScript 4.0 cast. The reader code is unchanged, so HyperFormula reads every key as before.

Upstream's 6.0.0 major release changes the key generator (prose templates, record fields, default schema), not the reader or the payload format.

How did you test your changes?

• node hyperformula/script/check-license-key-parser-drift.js: 13 files ok, exit 0. With one byte added to README.md, it reports the difference and exits 1.
• Full Jest suite with the develop branch of hyperformula-tests, unchanged: 520 of 520 suites pass; 6742 tests pass, 3 skipped. No paired tests branch: no reader code changed.

Compatibility with Excel and Google Sheets

Not applicable.

Public API changes

None.

Out of scope and follow-ups

• The license test fixtures in hyperformula-tests were minted with license-key 5.1.1. They read the same with this reader, but their header says 5.1.1 is the version HyperFormula vendors.
• The fixture README says to drop the token stand-ins and remint once the generator accepts fun:* and feat:* tokens. The 6.x generator accepts them. Reminting is a separate change.

Types of changes

• Breaking change (existing functionality no longer works as before) – agreed with the maintainers
• New feature or improvement (a non-breaking change that adds functionality)
• Bug fix (a non-breaking change that fixes an issue)
• Additional language file, or a change to an existing language file (translations)
• Change to the documentation

Note

Low Risk
Documentation and upstream pin only; reader implementation unchanged, so license validation behavior should be identical.

Overview
Re-syncs the vendored entitlement-key reader with upstream license-key tag 6.1.0 so the drift check passes again (newer tags existed while the pin still pointed at 5.1.1).

Pin and provenance: upstream.json and PROVENANCE.md now record tag 6.1.0, commit 824cfd4bc, and taken_on 2026-10-25. The single allowed local divergence in extractKeyData.ts (TypeScript 4.0 cast) is unchanged.

Docs only: README.md is brought in from upstream 6.1.0—the only file that differed between 5.1.1 and 6.1.0 in that directory. Updates include HyperFormula fun: / feat: capability examples instead of legacy functions_* / spreadsheet, guidance that hasCapability is exact-match and that HyperFormula expands fun:all, feat:all, and group tokens in its own registry, and a revised license-key CLI fixture command listing spec Example 1 tokens.

Runtime: No .ts reader changes; key parsing behavior is intended to stay the same.
