The pipeline

This is the specification the analyses were produced by — the flf-epistack Claude Code skill, published here so the method is auditable without cloning anything. It is the same text the agents actually execute, not a write-up of it.

The pipeline runs as one orchestrator plus per-step child agents. Each step below states what it consumes, what it must write, and the checks that gate it before the next step starts.

1. The skill definition — the entry point: node ontology, folder layout, the rules every step obeys, and the invocation contract.

The ten steps

1. Step 0 — Orchestrate the run
2. Step 1 — Find primary sources
3. Step 2 — Curate sources
4. Step 3 — Extract observations, hypotheses, and arguments from a paper
5. Step 4 — Structure hypotheses
6. Step 5 — Link observations to hypothesis-clusters
7. Step 6 — Assess argument validity
8. Step 7 — Estimate priors
9. Step 8 — Estimate likelihoods per (cluster, observation)
10. Step 9 — Per-cluster review of the analysis
11. Step 10 — Final report answering the main question

The code

The runner and helper scripts live in this folder and are served here as raw source (GitHub renders them more nicely — browse the folder on GitHub):

1. runner/run.py
2. runner/test_run.py
3. scripts/attach_argument_backlinks.py
4. scripts/batch_arguments.py
5. scripts/batch_likelihoods.py
6. scripts/build_correlation_groups.py
7. scripts/check_missing_evidence_links.py
8. scripts/create_node.py
9. scripts/curation_select.py
10. scripts/no_observation_arguments.py

The runner (runner/run.py) is the piece that makes the answer recompute: it extracts the ## Prior and ## Likelihood python blocks from the notes, enforces determinism (arithmetic over named variables only — no imports, randomness, clock or I/O), and composes each cluster’s posterior. runner/test_run.py checks it against the numbers the step 7 and 8 specs publish.

Frozen submission snapshot

This folder is the pipeline as of the FLF submission deadline — kept fixed so the /v1/ URLs stay honest. The living skill, which may change over time, is at .claude/skills/flf-epistack/ in the repo. Wikilinks appearing in the step specs are syntax examples, shown verbatim rather than linked.
