We build the working pilot and ramp up your team to take it forward. en-US https://singular-state.com/experiments/encarta-revival-where-ai-written-code-breaks/ https://singular-state.com/experiments/encarta-revival-where-ai-written-code-breaks/ Wed, 09 Sep 2026 00:00:00 +0000 An agent built a Tauri desktop application end to end. The pure logic was correct on the first or second attempt. Every defect that mattered sat at a boundary no headless test can reach. https://singular-state.com/experiments/four-experiments-in-ai-assisted-reconstruction/ https://singular-state.com/experiments/four-experiments-in-ai-assisted-reconstruction/ Wed, 09 Sep 2026 00:00:00 +0000 A scanned NASA specification, a novel, the memory of a product, and a sealed algorithm. What four controlled rebuilds establish about where AI-assisted reconstruction of legacy systems actually fails. https://singular-state.com/experiments/grading-a-reconstruction-against-a-sealed-answer-key/ https://singular-state.com/experiments/grading-a-reconstruction-against-a-sealed-answer-key/ Wed, 09 Sep 2026 00:00:00 +0000 A compressor reconstructed from behaviour alone, graded against an answer key sealed until the work was frozen. The decoder scored 100 percent and the encoder 8.3 percent on the same format. https://singular-state.com/experiments/hal-s-reconstruction-from-a-degraded-spec/ https://singular-state.com/experiments/hal-s-reconstruction-from-a-degraded-spec/ Wed, 09 Sep 2026 00:00:00 +0000 HAL/S runs again: twelve preserved Shuttle-era programs, verified value-for-value against an independent interpreter. The load-bearing human work was refusing a majority vote between OCR engines. https://singular-state.com/articles/accounting-boundary-shapes-architecture/ https://singular-state.com/articles/accounting-boundary-shapes-architecture/ Mon, 07 Sep 2026 00:00:00 +0000 Capitalisation rewards crossing from exploration into development, so the boundary quietly rewards early commitment to a design. An incentive on technical decisions nobody describes as technical. https://singular-state.com/articles/boring-technology-and-the-debt-you-write-down/ https://singular-state.com/articles/boring-technology-and-the-debt-you-write-down/ Mon, 07 Sep 2026 00:00:00 +0000 Familiar means familiar to the receiving team, not old. And the ledger records what the code cannot do, including the debt nobody chose. https://singular-state.com/articles/the-evaluation-harness-is-the-deliverable/ https://singular-state.com/articles/the-evaluation-harness-is-the-deliverable/ Mon, 07 Sep 2026 00:00:00 +0000 The system can be rebuilt; the encoded definition of working cannot. Ship the harness first, and test it by making a deliberately wrong answer fail. https://singular-state.com/articles/throwaway-or-evolutionary/ https://singular-state.com/articles/throwaway-or-evolutionary/ Mon, 07 Sep 2026 00:00:00 +0000 Whether prototype code survives is a decision per component, made in advance, and separate from whether the learning survives. Neither always-rewrite nor demo-implies-retain holds. https://singular-state.com/articles/walking-skeleton-tracer-bullet-strangler-fig/ https://singular-state.com/articles/walking-skeleton-tracer-bullet-strangler-fig/ Mon, 07 Sep 2026 00:00:00 +0000 Three patterns that build a thin end-to-end path before breadth. Two of them overlap and the third is a different kind of thing, because it has to keep an incumbent running alongside.
