Pass 4 (claude-opus-4-8) scoped-diff verification of gpt-5.5's pass-3 patches
(07a1b7c, 3aa8011, 6cea6b0). No plan-file changes: all three held up and pass 4
found no new plan issues.
New findings this pass: 0 (BLOCKER 0, GAP 0, SIMPLIFY 0, QUESTION 0).
Verification results (grounded in generated artifacts / installed tools):
- 07a1b7c piStatusInstall (original-plan defect, patched pass 3): CORRECT. Test
#1a passes against the materialized helper; the fixtures fail against the old
inline ln -sfn on the regular-file/directory/custom-symlink cases (principle
11). ln -sfnT refuses to overwrite a real directory, so it cannot write inside
one. A synthetic writeText closure eval confirms the pass-1 transitive-
realization subtlety did not reappear (piext/claudesh extracted from the helper
files exist on disk; the extension/statusline paths are absent from .data yet
realized in its closure). Non-fatal under the shared set -eu -o pipefail.
Proportionate - kept, not simplified (fixtures load-bearing; same factoring
rationale as claudeStatusMerge; a bare ln -sfnT would still silently clobber
operator state).
- 3aa8011 Codex exclusion (original-plan defect, patched pass 3): CORRECT against
the realized codex 0.142.5 source. All 26 StatusLineItem variants are built-in
and EnumString-parsed; no Custom/Text/Command/Exec/Script variant; unknown ids
are warned-and-ignored via parse_items_with_invalids / status_surfaces.rs.
Plan's item list matches. No custom-text or external-command hook exists.
- 6cea6b0 warnEcho visibility (introduced by pass-2 ba7d476's || true wording,
patched pass 3): CORRECT. warnEcho is defined in the sourced home-manager.sh and
in scope for the agentVmStatus snippet; ${helper} || warnEcho is non-fatal and
continues activation; the check greps enforce non-fatal+warn and fail on
regression to fatal or || true. Corrected visibility wording is accurate.
- Non-fatal ordering rationale re-verified against the current allod-dev DAG
(faithful topoSort replay): agentVmStatus sorts to the front of the
post-writeBoundary group; installPackages and syncPrBranchProtection sort after
it, so non-fatality (not ordering) is the required containment.
SIMPLIFY sweep: considered deleting/inlining the piStatusInstall helper (weighed
its store artifact + fixtures against principle 15) and re-checked the
claudeStatusMerge/claudeStatusLine split and the .statusLine linkage assertion.
Cut nothing: each helper's factoring is required by its behavioral test, and the
never-clobber charter needs piStatusInstall's guards (not just ln -sfnT). No
residual ceremony found.
Stop conditions: not yet met. Pass 4 is the first clean pass (no BLOCKER, no
original-plan GAP); pass 3 was not clean. One more clean pass meets condition 2.
Next pass 5: fresh full convergence pass, prefer claude-sonnet (not
claude-opus-4-8).
Model: claude-opus-4-8
