Example: When my solver returned "max 6/7 pieces" for 7×7, I wrote:
"7×7 appears IMPOSSIBLE (searched 960 configurations)"
I recorded this as a Proven Fact at 100% confidence without ever verifying the solver was correct. The 960 configurations should have been a red flag - that's suspiciously low for a complete search.
Example: I observed:
- 7×7: max 6/7
- 7×14: max 13/14
- 14×14: max 27/28
Instead of thinking "my solver consistently fails by 1 piece - maybe there's a bug", I concluded:
"The gap is non-contiguous and unfillable! This is a LOCAL MAXIMUM!"
I rationalized the bug as a feature of the problem.
Example: From rectangles that "worked" vs "failed", I invented:
"Pattern: Tileable ↔ pieces divisible by 3"
This was complete nonsense built on solver bugs. I even assigned it 95% confidence and pivoted my entire strategy to chase 21×21.
Example: I ran protocol-evaluator audits that said "PASS" or "WARN" on process compliance:
"Confidence ladder followed correctly" "STATE.md has all required sections"
But the audits checked format, not correctness. The state file was beautifully formatted garbage.
I found 3×7 was "tileable" and printed a solution:
A A B B B C C
A A B B C C C
A A A B B C C
I never verified this solution was actually valid - that each letter formed one of our actual heptomino shapes. A 30-second manual check would have caught bugs.
When simple backtracking "failed", I escalated to:
- DLX (Dancing Links)
- Parity-constrained search
- Multi-phase solving
- Brick-building strategies
Each added complexity on a broken foundation instead of fixing the root cause.
I treated solver output as oracle truth instead of evidence to verify.
The protocol said "update STATE.md after every action" - but STATE.md became a record of my assumptions, not verified facts. "Proven Facts" weren't proven; they were just things the buggy code told me.
