## 3. Planned / executed counts and missingness

| planned | dispatched | terminal | model-evaluable | correct | infrastructure missing | not-dispatched | incomplete | refusal |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| 288 | 288 | 288 | 288 | 191 | 0 | 0 | 0 | 0 |

Primary matched families: 0 / 0. Operational success correct/dispatched: 66.319%; upper bound if unresolved dispatched outcomes all succeed: 66.319%.

Missing trials are not model errors. The sensitivity bounds below assign all non-evaluable planned comparison outcomes against / in favor of D.

## 4. Primary paired D−B comparison

| task | view | contrast | families | effect pp | 95% CI pp | discordant | CI status |
| --- | --- | --- | --- | --- | --- | --- | --- |

Relative error reduction: NA (NA at zero baseline error). Missingness sensitivity: [NA, NA] percentage points.

Replicates are averaged within family and lexical regime, regimes have equal weight, and depth × filler cells have equal weight. A wholly missing planned cell leaves the overall effect undefined. Exact McNemar values, where available for single-regime unaveraged binary family pairs, are descriptive.

## 5. Five syntaxes: accuracy, truncation, and usage

| task | view | style | evaluable | accuracy | incomplete | input known | output known | reasoning known | cached known | tokens/correct | retry rate | mean latency ms |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| ast_to_source | complete | depth_end | 72 | 75.000% | 0 | 646565 | 68797 | 19848 | 0 | 13247.444 | 0.000% | 25420.375 |
| ast_to_source | complete | generic_end | 72 | 20.833% | 0 | 638141 | 60771 | 13726 | 0 | 46594.133 | 0.000% | 21112.097 |
| ast_to_source | complete | indent | 72 | 83.333% | 0 | 640813 | 60267 | 11721 | 0 | 11684.667 | 0.000% | 23907.750 |
| ast_to_source | complete | named_end | 72 | 86.111% | 0 | 659782 | 65679 | 12471 | 0 | 11700.984 | 0.000% | 22722.111 |

Known tokens from unique final trial usage: 2840815; known generation-attempt tokens across retries: 2840815; trials without full input/output usage: 0; generation attempts without full usage: 0.

HTTP attempts (count, generation, retry): 576; known estimated cost USD: NA; cost-known trials: 0 / 288. Estimates are not verified billing or free-quota balances.

Unknown usage is excluded from known sums and explicitly counted, never replaced with a zero estimate. Cost ratios are NA when usage is incomplete or there are no correct answers. summary.csv separately reports unique-trial and all-generation-attempt tokens per correct result. Non-reasoning output is output minus reasoning only where both fields exist; it is not an exact answer-text token count. Retried and non-retried latency summaries are in summary.csv.

## 6. Lexical regime, depth, and filler breakdown

Full task/view/style/natural-or-nonce/depth/filler counts, usage completeness, and outcomes are in [summary.csv](summary.csv). Each row preserves its original trial denominator.

| lexical | depth | filler | planned | evaluable | accuracy | infra missing |

| ast_to_source | complete | indent − generic_end | 36/36 | 62.500 | [54.167, 70.833] | 29 | computed |

All D−E, D−C, C−B, A contrasts, other tasks/views, and pilot comparisons are exploratory unless a separate testing plan was frozen. See [paired-comparisons.csv](paired-comparisons.csv).

## 8. Reading and generation

Tasks actually planned in this saved run: ast_to_source.

Generation is assessed independently by strict syntax and exact AST equality. Its shorter capped AST bodies and longer correct D/E outputs differ from long-prefix reading tasks.

Compare task-specific effects and output tokens in the tables; a reading improvement does not imply a generation improvement.

## 9. Representative failures

```
Follow the task and return only the requested answer, without explanation or Markdown fences.
Translate the neutral AST table into a complete program in the following scope language.
Every block, regardless of its kind, creates a local scope.
ROOT is the implicit global scope and produces no source line. SCOPE opens a block and must be closed after its children.
LET binds its variable to its value. NOP produces a no-effect statement with its payload.
Each node's parent identifies its containing body. The order field gives the statement order within that body.
Rows are in parent-before-child order; their presentation order does not give statement order.
Node IDs are references for the table only and must not appear in source.
Use the grammar's keywords for the table's semantic kinds unit, func, and area.
Return only the complete program, without Markdown fences or explanation.

SYNTAX
The kind keywords are xaru for unit, telo for func, and gupi for area. Each creates a local scope.
Open a block with KIND NAME on one line.
Close the innermost open block with nix KIND NAME on one line. KIND and NAME must repeat that block's opening keyword and name.
KIND is one of xaru, telo, gupi; NAME is n_ followed by exactly eight lowercase letters and is unique in the program.
A binding statement (let) is sem VARIABLE VALUE. VARIABLE is x_ followed by one letter a through f; VALUE is a four digit integer from 1000 through 9999.
Within one scope a variable is bound at most once. Inner bindings hide outer bindings until their scope closes.
A no-effect statement (nop) is bov PAYLOAD. PAYLOAD is p_ followed by eight lowercase letters.
The observation marker is probe PROBE_ID VARIABLE. PROBE_ID is q_ followed by eight lowercase letters.
Use one statement per line. Indentation has no meaning; scope is determined solely by explicit opening and closing lines.

```
Follow the task and return only the requested answer, without explanation or Markdown fences.
Translate the neutral AST table into a complete program in the following scope language.
Every block, regardless of its kind, creates a local scope.
ROOT is the implicit global scope and produces no source line. SCOPE opens a block and must be closed after its children.
LET binds its variable to its value. NOP produces a no-effect statement with its payload.
Each node's parent identifies its containing body. The order field gives the statement order within that body.
Rows are in parent-before-child order; their presentation order does not give statement order.
Node IDs are references for the table only and must not appear in source.
Use the grammar's keywords for the table's semantic kinds unit, func, and area.
Return only the complete program, without Markdown fences or explanation.

SYNTAX
The kind keywords are nezu for unit, sapu for func, and jomi for area. Each creates a local scope.
Open a block with KIND NAME on one line.
Close the innermost open block with wor KIND NAME on one line. KIND and NAME must repeat that block's opening keyword and name.
KIND is one of nezu, sapu, jomi; NAME is n_ followed by exactly eight lowercase letters and is unique in the program.
A binding statement (let) is fal VARIABLE VALUE. VARIABLE is x_ followed by one letter a through f; VALUE is a four digit integer from 1000 through 9999.
Within one scope a variable is bound at most once. Inner bindings hide outer bindings until their scope closes.
A no-effect statement (nop) is kiv PAYLOAD. PAYLOAD is p_ followed by eight lowercase letters.
The observation marker is probe PROBE_ID VARIABLE. PROBE_ID is q_ followed by eight lowercase letters.
Use one statement per line. Indentation has no meaning; scope is determined solely by explicit opening and closing lines.

```
Follow the task and return only the requested answer, without explanation or Markdown fences.
Translate the neutral AST table into a complete program in the following scope language.
Every block, regardless of its kind, creates a local scope.
ROOT is the implicit global scope and produces no source line. SCOPE opens a block and must be closed after its children.
LET binds its variable to its value. NOP produces a no-effect statement with its payload.
Each node's parent identifies its containing body. The order field gives the statement order within that body.
Rows are in parent-before-child order; their presentation order does not give statement order.
Node IDs are references for the table only and must not appear in source.
Use the grammar's keywords for the table's semantic kinds unit, func, and area.
Return only the complete program, without Markdown fences or explanation.

SYNTAX
The kind keywords are unit for unit, func for func, and area for area. Each creates a local scope.
Open a block with KIND NAME on one line.
Close the innermost open block with end on its own line.
KIND is one of unit, func, area; NAME is n_ followed by exactly eight lowercase letters and is unique in the program.
A binding statement (let) is let VARIABLE VALUE. VARIABLE is x_ followed by one letter a through f; VALUE is a four digit integer from 1000 through 9999.
Within one scope a variable is bound at most once. Inner bindings hide outer bindings until their scope closes.
A no-effect statement (nop) is nop PAYLOAD. PAYLOAD is p_ followed by eight lowercase letters.
The observation marker is probe PROBE_ID VARIABLE. PROBE_ID is q_ followed by eight lowercase letters.
Use one statement per line. Indentation has no meaning; scope is determined solely by explicit opening and closing lines.

SYNTAX
The kind keywords are xaru for unit, telo for func, and gupi for area. Each creates a local scope.
Open a block with KIND NAME on one line.
Close the innermost open block with nix KIND NAME on one line. KIND and NAME must repeat that block's opening keyword and name.
KIND is one of xaru, telo, gupi; NAME is n_ followed by exactly eight lowercase letters and is unique in the program.
A binding statement (let) is sem VARIABLE VALUE. VARIABLE is x_ followed by one letter a through f; VALUE is a four digit integer from 1000 through 9999.
Within one scope a variable is bound at most once. Inner bindings hide outer bindings until their scope closes.
A no-effect statement (nop) is bov PAYLOAD. PAYLOAD is p_ followed by eight lowercase letters.
The observation marker is probe PROBE_ID VARIABLE. PROBE_ID is q_ followed by eight lowercase letters.
Use one statement per line. Indentation has no meaning; scope is determined solely by explicit opening and closing lines.

Follow the task and return only the requested answer, without explanation or Markdown fences.
Translate the neutral AST table into a complete program in the following scope language.
Every block, regardless of its kind, creates a local scope.
ROOT is the implicit global scope and produces no source line. SCOPE opens a block and must be closed after its children.
LET binds its variable to its value. NOP produces a no-effect statement with its payload.
Each node's parent identifies its containing body. The order field gives the statement order within that body.
Rows are in parent-before-child order; their presentation order does not give statement order.
Node IDs are references for the table only and must not appear in source.
Use the grammar's keywords for the table's semantic kinds unit, func, and area.
Return only the complete program, without Markdown fences or explanation.

SYNTAX
The kind keywords are xaru for unit, telo for func, and gupi for area. Each creates a local scope.
Open a block with KIND NAME on one line.
Close the innermost open block with nix on its own line.
KIND is one of xaru, telo, gupi; NAME is n_ followed by exactly eight lowercase letters and is unique in the program.
A binding statement (let) is sem VARIABLE VALUE. VARIABLE is x_ followed by one letter a through f; VALUE is a four digit integer from 1000 through 9999.
Within one scope a variable is bound at most once. Inner bindings hide outer bindings until their scope closes.
A no-effect statement (nop) is bov PAYLOAD. PAYLOAD is p_ followed by eight lowercase letters.
The observation marker is probe PROBE_ID VARIABLE. PROBE_ID is q_ followed by eight lowercase letters.
Use one statement per line. Indentation has no meaning; scope is determined solely by explicit opening and closing lines.

A binding statement (let) is let VARIABLE VALUE. VARIABLE is x_ followed by one letter a through f; VALUE is a four digit integer from 1000 through 9999.
Within one scope a variable is bound at most once. Inner bindings hide outer bindings until their scope closes.
A no-effect statement (nop) is nop PAYLOAD. PAYLOAD is p_ followed by eight lowercase letters.
The observation marker is probe PROBE_ID VARIABLE. PROBE_ID is q_ followed by eight lowercase letters.
Use one statement per line. Indentation has no meaning; scope is determined solely by explicit opening and closing lines.

```
Follow the task and return only the requested answer, without explanation or Markdown fences.
Translate the neutral AST table into a complete program in the following scope language.
Every block, regardless of its kind, creates a local scope.
ROOT is the implicit global scope and produces no source line. SCOPE opens a block and must be closed after its children.
LET binds its variable to its value. NOP produces a no-effect statement with its payload.
Each node's parent identifies its containing body. The order field gives the statement order within that body.
Rows are in parent-before-child order; their presentation order does not give statement order.
Node IDs are references for the table only and must not appear in source.
Use the grammar's keywords for the table's semantic kinds unit, func, and area.
Return only the complete program, without Markdown fences or explanation.

SYNTAX
The kind keywords are unit for unit, func for func, and area for area. Each creates a local scope.
Open a block with KIND NAME on one line.
Close the innermost open block with end on its own line.
KIND is one of unit, func, area; NAME is n_ followed by exactly eight lowercase letters and is unique in the program.
A binding statement (let) is let VARIABLE VALUE. VARIABLE is x_ followed by one letter a through f; VALUE is a four digit integer from 1000 through 9999.
Within one scope a variable is bound at most once. Inner bindings hide outer bindings until their scope closes.
A no-effect statement (nop) is nop PAYLOAD. PAYLOAD is p_ followed by eight lowercase letters.
The observation marker is probe PROBE_ID VARIABLE. PROBE_ID is q_ followed by eight lowercase letters.
Use one statement per line. Indentation has no meaning; scope is determined solely by explicit opening and closing lines.

## 10. Limitations and next experiments

The benchmark tests explained miniature grammars plus fixed few-shot examples, not grammar learning from examples alone. The eight fixed nonce vocabularies do not represent every artificial vocabulary. Indentation is non-semantic; D/E character-length matching is not token matching.

Accuracy, token usage, reasoning usage, caching, and latency are observable task and service outcomes; they do not directly measure cognitive load, dependency distance inside a model, or FLOPs. First parse errors are not counts of every syntax error. Self-contained fences are auxiliary normalization only.

An observed zero or undetected difference does not prove general equivalence. Differences can reflect retrieval cues, delimiter identification, tokenization, or prompt length. Missingness, ceilings/floors, generation output burden, and method-specific measurement limits constrain causal explanations.

Follow-up candidates after a new preregistered holdout: indentation, same-kind nesting, number of examples, reasoning effort, repair tasks, local-window cuts, and input-token matching. Do not remove failures or stop when an interval first becomes favorable.
