From 2f5383d230008635e02f03bb5ecd5851547c4ce9 Mon Sep 17 00:00:00 2001 From: Daniel McCoy Stephenson Date: Sat, 29 Aug 2026 02:07:36 -0600 Subject: [PATCH 1/2] Ground Phase 4's Docs score in a real pass and fix two Phase 3 rules MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 4's Docs rubric item named a check that Phase 7 does not perform until three phases later, so the item could only ever be scored from judgment — the thing the rubric's own framing forbids — and a clean Phase 7 sweep left no trace that would distinguish it from a skipped one. The table pass now happens at Phase 4, where the score is taken; Phase 7 becomes a re-check scoped to whatever Phases 5-6 changed, with an explicit instruction to record that it ran. Phase 3's zero-tests rule ended by describing {{TEST_CMD}} as a substitution, which is the one context a generated child skill never has: after substitution it read "fall back to whatever the ./gradlew test substitution names". It now names the executed-test count as the gate, which reads correctly on both sides of substitution. A scan of the rest of the template body found no other sentence referring to a token as a token. Phase 3's scratch-file rule gains a third cleanup form observed to work where a bare rm is blocked: git clean -f on a single untracked path inside the working tree, previewed with git clean -n.

Observed effect: pending — needs N cycles of data. Two more ways the anchor silently weakens at the merge phase: the post-rebase verification ran the test command alone, so a required check covering a linter or static analysis was never part of the signal a force-push committed to (#115); and nothing stated whether a run-level merge pre-authorization could stand in for a Phase 4 UNVERIFIED result (#118). Both are the same failure this finding's PR #54 entry records for CI scope — an anchor that does not cover the changed surface is not an anchor — applied to permission rather than coverage in the second case. - PR #121 (Define the structurally-red-anchor path and require the anchor to have executed tests): shipped 2026-08-16. Observed effect: pending — needs N cycles of data. Extends the same argument as PR #54's "green CI is not verification when CI's scope excludes the changed files" to two further ways an anchor can carry no information: a required job that has *never* succeeded on the base branch (observed on a repo whose CI jobs have failed on empty credentials since February 2026, so every cycle terminated in a hand-off regardless of quality), and a build tool that reports success having executed zero tests (`:test NO-SOURCE` still prints `BUILD SUCCESSFUL`). Both were previously read as ordinary signals — the first as a blocking red, the second as a green — which is unanchored critique wearing an anchor's clothes. - PR #136 (Make the checkout form Phase 4's default Tests-fix revert and gate ladder rung 1): shipped 2026-08-25. Observed effect: pending — needs N cycles of data. Repairs the mechanism PR #54's entry above introduced. The prescribed `git stash push` revert ran against a tree Phase 3 had already committed and Phase 4 had already pushed, so it saved nothing, the check then passed against the still-fixed tree, and the no-op was naturally scored as a false-negative in the *test* — an anchor reporting a verdict it never measured, which is precisely the failure this finding warns about. The checkout form becomes the default because it is correct in the state Phase 4 actually finds, and the revert must now be confirmed to have changed the tree before either half is trusted. Separately, the ladder rung PR #67 added is gated against headless dispatch, where an interrupted session leaves the branch head undoing its own fix and the substitute anchor damages the thing it substitutes for. +- PR #138 (Ground Phase 4's Docs score in a real pass): shipped 2026-08-29. Observed effect: pending — needs N cycles of data. The **Docs** rubric item named a check that Phase 7 did not perform until three phases later, so the only way to score it on time was from judgment — an anchor-shaped item with no anchor behind it, the same defect as PR #121's zero-executed-tests green, relocated from the signal to the schedule. The table pass now runs at Phase 4, where the score is taken, and Phase 7 is reduced to a re-check of whatever the review phases changed. Phase 7 is also required to record that it ran, since a clean sweep that leaves no artifact is indistinguishable from a skipped one — which is the auditability half of the same problem. ---
