SDK 0.6.1 README banner and plain-text guideline — 2026-10-30

CC supplied the public Cloudinary URL for the approved SDK banner. The README
now embeds that exact image once above its version heading, with alt text
PyCForge SDK and display width 640. All previously approved prose and examples
are byte-identical after the new image prefix.

PyCForge-SDK-README-Guidelines.txt is the canonical plain-text instruction file.
It records the exact image URL, markup, placement, prose requirements, human/AI
use, engine-supplied updates, version checks and release preservation rules.
AGENTS.md points to it; MANIFEST.in includes it in source distributions.
The previous Markdown guideline is retained as supporting editorial context.

The distribution checker was aligned with the new banner-first README: it
matches the package version rather than hardcoding the old SDK 0.6.0 version,
checks the exact approved image prefix and URL inventory, requires the guideline,
and compares UTF-8 README payload bytes without email charset reinterpretation.
Existing payload, RECORD, dependency, entry-point and preservation checks remain.

The public image returned HTTP 200 with image/png content and decodes correctly
at 2172 x 724. Visual review confirms the approved original code-bracket logo.
Strict Markdown rendering keeps the image above the heading at width 640 with
no warnings. The rendered header was visually reviewed. Detailed image and
markup checks are retained in evidence/readme_banner_2026_10_30.

The previously verified command/Python examples are unchanged and were not
rerun for the image-only change. Application code, engine logic and import
semantics are unchanged. Final archive checks and new hashes are recorded in
the separate handoff report. No publication was performed; CC alone publishes.
