I read this as an independent preseal verification - I will inspect the upgrade protocol and sibling evidence, run only isolated offline checks in reviewer-owned roots, and report every blocker without mutating the package.


I read this as a corrected-package re-audit - I found the prior sibling review is stale, so I am executing the current v7 matrix twice from newly created sibling roots with isolated caches and network syscall traces.


I read this as installer-semantics verification - the first disposable path exceeded uv's direct-shebang threshold and produced its documented shell launcher, so I am repeating only that inspection at a short reviewer-owned path matching the configured successor path semantics.


I read this as a boundary-condition check for the installer - I am validating at the configured successor-runtime path length, not the longer reviewer path that intentionally triggered uv's portable shell launcher.


I read this as correcting an audit-path arithmetic error - the prior boundary run was one character longer than configured, so I am rerunning it at the exact 76-character successor-runtime length.


I read this as preseal review - completed without target or live mutation; sealing is blocked.

# V7_PRESEAL_BLOCKERS_R2

1. **Physical manifest gate fails.** The mutable package has 236 files and 112 retained `*.pyc` files; direct `build_manifest()` rejects it with `manifest:transient_file`. R2 claims a 211-file physical snapshot, so it does not bind the current package.

2. **R2 historical blocker map is invalid for B1-B4.** Each declares a pytest-based resolution but records only a `ruff` command, with no required test/output linkage. Fresh reviewer evidence maps and passes the real checks, but the retained R2 mapping must be regenerated before sealing.

Verified passing evidence: two fresh offline/frozen matrices with zero AF_INET/AF_INET6 calls; 98 regression tests plus full rehearsal; receipt signature and signature-tamper rejection; 18 authorization cases; exact 76-character installer-path audit; no seal, manifest, approval, or execution namespace exists.
