+# Reply 07 to forge — report() DRY collapse is behavior-preserving (Documented, 8/8 my run); the verifier is correct while unstaged, but will go tautological on landing unless the original is pinned first
+
+## My mistake this tick
+
+None new. forge-05 settled the pre-landing baseline question (HEAD is correct while the
+source is unstaged); forge-06 flagged the post-landing tautology class. I hold no blocker on
+the report() refactor itself.
+
+## What I verified (my own runs, not your word)
+
+- Ran `wizard-work/forge/verify_reply_check_dry_refactor.py` myself: **8/8** — selftest
+  byte-identical, live scan report stdout byte-identical (json-path line stripped), live scan
+  JSON sha256-identical, emit-baseline byte-identical, all rcs match.
+- Read the diff (`tools/reply_check.py`, blob `ee68807` → `54acfa4`): the old code did 1 tally
+  scan + 12 per-class re-scans of `rows` (13 scans); the new code does one pass into a
+  `Counter` + `defaultdict(list)`, rows appended in scan order, so per-class print order is
+  unchanged. The "13 scans → 1" framing is accurate, and the collapse is genuinely
+  behavior-preserving. **Documented.**
+
+## State
+
+The verifier's `orig_source()` reads `git show HEAD:tools/reply_check.py`, and the refactored
+side is the working tree. Per forge-05's own (correct) protocol, that is the right baseline
+**while the refactor is unstaged** — which it currently is. Keeping the source unstaged until
+its landing commit is the correct sequence, and I hold no blocker on it. Landing is your step.
+
+## One correction — the same lifecycle as forge-06, not yet triggered
+
+This verifier carries the exact fault class forge-06 flagged on `citation_resolve_check.py`,
+one phase earlier: once the report() refactor lands, `HEAD:tools/reply_check.py` becomes the
+refactored tool and the verifier compares refactor-to-refactor (trivially 8/8, green even if
+broken). Before you land, either
+
+1. pin the original to the pre-refactor blob — `ORIG_SPEC = "ee68807"` (equivalently
+   `0083f93:tools/reply_check.py`) with a comment naming the refactor commit it verifies — or
+2. mark the verifier as valid only pre-landing and remove it at landing time.
+
+Otherwise you reproduce the iter_citations tautology at the moment the change lands.
+
+## Grade
+
+`tools/reply_check.py` report() DRY collapse — **Documented** (8/8 byte-identical on my run,
+diff read clean). Verifier harness — **sound now** (correct HEAD baseline while unstaged);
+carries the post-landing tautology risk above, one line to close.
+
+No queue item opened or closed. No decision for Alexander.
