# Author visual observations (not human or expert grades)

## draft1 — refused, no full submission
Drawing read: `out/t0_p336d70065d_draft_draft1.png`.
All three through holes and all three level boundaries were retained. The rectangular region's hole and the capsule interior are isolated, and their 2-D checks pass. The top-left hole's enclosure is compact; however, its background connections visibly cross or fold. The circular boss's diamond enclosure was too small between its vertices and cuts into the circular boundary. The left hole's enclosure is locally symmetric but connects to overly broad, poorly oriented wedges. The right outer round is not properly isolated: one intended quad has a straight boundary corner and another nearly collapses. No full submission is justified. Rebuild those transitions; retain the successful level-region structure. Do not chase failed numbers by arbitrary subdivisions.

## draft2 — refused, substantial repair review
Drawing read: `out/t0_p336d70065d_draft_draft2.png`.
The left features are now separately enclosed and the boss has a material core. Hole 2's compact box is symmetric; the upper hole and boss share an enclosure junction because of their proximity. Their local enclosures are visibly skewed by that crowding, but the rings pass 2-D. The background is much more coherent, with no long crossed fans; however, the narrow three-block transition at the right of hole 2 is poor, and the capsule's enclosure was extended too far right, producing a very shallow bottom fan. The rightmost round still has a folded partition. The extra midpoint cuts are a fixed conforming continuation of two hand-chosen triangular transitions, not numerical search; they add noticeable complexity. Revise those three geometric weaknesses. The structural check accepts 64 base blocks and irregularity 22/36; no thin-strip mark is reported, but the visual narrow left transition remains unacceptable to me.

## drafts3–4 — repair observations
Drawings read: `out/t0_p336d70065d_draft_draft3.png` and `out/t0_p336d70065d_draft_draft4.png`.
Draft3 omitted a small right-hand patch; the runner correctly refused entry. Draft4 fills it and no longer reports overlap or material leakage. The capsule enclosure is now appropriately narrow and its upper/lower transitions pass. The left through-hole enclosure became too tight vertically as a numerical compromise, and moving the boss's lower-left corner without a separate west station visibly squeezed its western ring. The upper hole's lower-right transition is also pinched. The right curved patch is locally thin despite the broader background. The 98-block count is visibly more subdivided than desirable; the structure check allows it, but the rule-11 detector marks a 0.45-wide chain carried 6.605 across the part. This is my author observation, not a grade. Revise the actual enclosure topology and the right curve before submitting; adding more cuts alone would not address these defects.

## draft5 → draft6 / candidate rev1 — submit for full checks
Drawings read: `out/t0_p336d70065d_draft_draft5.png` and `out/t0_p336d70065d_draft_draft6.png`.
All three through holes are isolated, the circular boss has a filled core and surrounding ring, and both other level boundaries have matching drawn blocks. Hole 2's enclosure is close to its diameter; its top and bottom clearance is small but the ring has positive shape margins. The upper hole's enclosure meets the boss enclosure at a shared corner, so local symmetry is imperfect there; the supplied feature arrangement has no global mirror symmetry. The capsule and boss interior cores retain useful local symmetry, though conforming background cuts subdivide some sides unequally. No feature has been removed.

The capsule enclosure is now near its width, rather than reaching across the right end. The right round has a coherent transition; draft6 moves one interior junction toward the arc without adding blocks. Broad skewed background blocks remain below the boss and in the left lower round, but their directions follow the sloping outer edge or connect nearby feature boxes. There are no long direct hole-to-outline fans. There are too many small background subdivisions near the boss, and the 0.45-wide rule-11 chain remains a real visual/numerical tradeoff. I do not claim this is an ideal minimal layout. The fixed conforming subdivisions isolate transitions and keep all level interfaces consistent; restructuring them again risks losing a valid submitted candidate in this bounded session.

Decision: submit draft6 as rev1. It passes every 2-D region, minimum corner sine 0.4326; base irregularity 24/36; forecast edge ratio 9/50; at least six sides around a loop. Total blocks 116, including 88 base. The full 3-D and doubled-density results will decide acceptance. These are author observations only.

## rev1 — full-run review, accepted by frozen checks
Drawing read after the full run: `out/t0_p336d70065d_rev1.png`.
The full-run drawing agrees with draft6: all holes and level boundaries remain isolated and material occupancy is correct. The right-round repair is coherent; no new visual defect appears after realization. The densely subdivided boss/background junctions, imperfect local symmetry at the crowded upper hole and boss, and the marked thin-block chain remain as documented above. No human/expert grade is inferred.

Full result: counted true, strict true, stable true, audit true, occupancy true, one mesh component. Minimum SJ is 0.43258322033005236 at nominal density and 0.4325832203300433 at doubled density; volume relative error -0.001519336609417071. These quality results support retaining the feature transitions despite the block-count/strip tradeoff. The brief requires stopping when counted, so no further repair or cosmetic revision is made.
