StefanandClaude Sonnet 5 c730ef6049 Pin vendored TinyMCE at 6.8.6 (ADR 0013)

6.8.6 is the last MIT-licensed release; 7.0+ requires a commercial
license. Documents the constraint and syncs it across CLAUDE.md,
CODEX.md, and copilot-instructions.md per the instruction-sync rule.

0013 — TinyMCE pinned to 6.8.6

Context

TinyMCE releases from 7.0 onward are licensed under a proprietary/commercial license (with a source-available "open core" carve-out that no longer covers the full feature set previously used). TinyMCE 6.8.6 is the last release published under the plain MIT license. The active app vendors TinyMCE directly under Fuchs/wwwroot/lib/tinymce/ (currently 6.8.6) rather than via a package manager that enforces license terms automatically. A second, older vendor drop lives at Fuchs/Scripts/tinymce/ (currently 6.3.1) used only by the legacy Intranet_Legacy VB.NET app — it is not required to match the active app's version, only to stay under the same ceiling.

Decision

TinyMCE must never be upgraded beyond 6.8.6, in either vendored copy. Any change that touches Fuchs/wwwroot/lib/tinymce/ must keep version in its package.json at 6.8.6 or lower. Do not pull in a newer TinyMCE release, plugin, or skin — including via npm/bower/composer metadata files bundled in the vendor folder — even to pick up a bug fix or new plugin.

Consequences

Security/bug fixes for TinyMCE past 6.8.6 will not be available; any such issue must be worked around locally (patch the vendored copy) rather than by upgrading.
New TinyMCE features/plugins released in 7.x+ are off-limits unless the project separately decides to accept the commercial license (a decision that would supersede this one).
The two vendored copies do not need to share the same version, but neither may exceed 6.8.6.

Alternatives considered

Upgrade to latest TinyMCE and accept the commercial license terms — rejected: no budget/approval for a commercial license, and the project has no other proprietary runtime dependencies of this kind.
Switch to a different MIT-licensed rich text editor — rejected for now as out of scope; would require rewriting the existing draft-editing integration (see Fuchs/Docs/Concepts/live-draft-editing.md). Can be revisited later.
