Table Schema (two layers: index vs Appendix)

Mission: choose tables that answer reader questions, not pipeline questions.

Do:

• make each table answer one question
• keep tables small enough to fill (two good tables beat one impossible mega-table)

Avoid:

• internal/log-style tables inside the paper
• column labels that only make sense inside this repo

Evidence Steward (fillability)

Mission: refuse schemas that require invented facts.

Do:

• map every column to concrete upstream fields
• reject columns that would force long paragraph cells

Avoid:

• TODO columns
• placeholders ("TBD", "...", "(placeholder)")

Workflow (explicit inputs)

• Use GOAL.md to keep the reader question and scope stable.
• Use outline/outline.yml to align table row units with the paper structure.
• Use outline/subsection_briefs.jsonl to ground table dimensions/axes in the approved structure.
• Use outline/evidence_drafts.jsonl to ensure every planned column is fillable without guessing.

Inputs

• outline/outline.yml
• outline/subsection_briefs.jsonl
• outline/evidence_drafts.jsonl
• Optional: GOAL.md

Output

• outline/table_schema.md

Non-negotiables (schema contract)

• Minimum definitions:
  • Index tables: >=2
  • Appendix tables: >=2
• Every table definition must include:
  • the question it answers
  • the row unit (H3 / benchmark / work / failure mode)
  • columns (with cell style constraints)
  • evidence mapping (which upstream fields fill which columns)
• Cell style: short phrases; avoid paragraph cells.
• Paper voice: Appendix table captions/columns must be publishable (no pipeline jargon).

Recommended defaults (arxiv-survey family)

Index tables (for table-filler -> outline/tables_index.md)

I1) Subsection map (axes + representative works)

• Row unit: H3
• Columns: subsection; axes; representative works
• Evidence sources: subsection_briefs.axes + citations from evidence_drafts

I2) Concrete anchors (benchmarks / numbers / caveats)

• Row unit: H3
• Columns: subsection; anchor facts; representative works
• Evidence sources: anchor_sheet.anchors

Appendix tables (for appendix-table-writer -> outline/tables_appendix.md)

A1) Method/architecture map (representative works)

• Row unit: work/system line
• Columns: work; core idea; loop + interface assumptions; key refs
• Evidence sources: evidence_drafts (comparisons + definitions) + anchor_sheet

A2) Evaluation protocol / benchmark map

• Row unit: benchmark or evaluation setting (fallback: protocol dimension)
• Columns: benchmark/setting; task+metric; key protocol constraints; key refs
• Evidence sources: anchor_sheet + evidence_drafts.evaluation_protocol

Positive / negative examples

Good (publishable question + fillable columns):

• Question: "Which benchmarks anchor evaluation in this area, and what task/metric/constraints do they imply?"
• Columns: Benchmark; Task+metric; Protocol constraints; Key refs
• Evidence mapping: evidence_drafts.evaluation_protocol + anchor_sheet

Bad (internal/pipeline voice):

• Question: "What is evidence readiness + verification needs?"
• Columns: evidence levels, missing fields, TODO checklist

If you want internal diagnostics, put them in an audit report, not in reader-facing tables.

Script (optional bootstrap)

Quick Start

• python .codex/skills/table-schema/scripts/run.py --help
• python .codex/skills/table-schema/scripts/run.py --workspace workspaces/<ws>

All Options

• --workspace <workspace_dir> (required)
• --unit-id <id> (optional; used only for runner bookkeeping)
• --inputs <outline;briefs;packs;goal> (optional; override inputs)
• --outputs <relpath> (optional; defaults to outline/table_schema.md)
• --checkpoint <C#> (optional; ignored by the bootstrapper)

Examples

• Bootstrap a two-layer schema (index + Appendix):

  python .codex/skills/table-schema/scripts/run.py --workspace workspaces/<ws>

• Write to a custom schema path (rare):

  python .codex/skills/table-schema/scripts/run.py --workspace workspaces/<ws> --outputs outline/table_schema.md

Notes:

• Use the script as a starting point, then refine the schema as a paper artifact.
• If a column cannot be filled from evidence packs without guessing, the schema is wrong.
