Verified this release-prep against the actual repo — everything checks out. Nice, careful bookkeeping.

Version bump — main is currently 26.6.5 in all three spots (CMakeLists.txt:2, README.md:13, AGENTS.md:171); the diff moves each to 26.7.1. CalVer is consistent (July → month 7, patch 1).

Commit accounting — git rev-list --count v26.6.5..HEAD returns exactly 29, matching the headline. I mapped every referenced PR back to a real merged commit in that range:

• Added (#3899, #3937, #3902, #3936, #3885, #3895, #3898, #3920), Changed (#3958, #3954/#2177, #3897, #3935), and all 13 Fixed entries (#3922, #3926, #3941, #3940, #3942, #3921, #3903, #3892, #3924, #3891, #3890, #3900, #3947) each correspond to an actual commit, and the descriptions match the commit subjects.
• The four omitted PRs (#3931, #3916, #3934, #3929) are genuinely bridge-build-fix / CI / docs commits — correct to leave out.
• 25 changelog'd + 4 omitted = 29. Full reconciliation, no phantom or miscategorized entries.

ROADMAP / README — NVIDIA BNR correctly moved from In flight to Recently shipped; the README GPU-spectrum highlight preserves the existing ~71% figure while adding the 60 fps / 3D notes. [Unreleased] is left empty above the release block, per house style.

One optional, pre-existing nit (not introduced here, and not blocking): AGENTS.md:171 still reads "set in both CMakeLists.txt and README.md" — the version actually lives in three places now (including AGENTS.md itself), which your PR body already acknowledges. Since you're editing that exact line anyway, you could tidy the wording, but it's fine to leave for a separate pass.

Docs-only, no behavior change, and the accounting is airtight. Thanks @ten9876 — LGTM. (Leaving as a comment; the @aethersdr/infrastructure protected-path sign-off you flagged still applies.)
