Firecrown likelihood for the tomographic ξ± layout + CAMB↔CCL cross-check #248
Description
Row 5 of the PRD #241 §7 table — the theory engine the blinding box (PR 6) will call.
Scope:
- minimal firecrown likelihood for our tomographic ξ± layout: consumes the analysis SACC file;
build_likelihood()+compute_theory_vector()is the whole surface Smokescreen uses; N-bin generic - fiducial cosmology + model configuration (halofit version, IA model, neutrino treatment) as one named, clearly-configurable default set — the PRD §5 open question changes config values, not code
- CAMB↔CCL cross-check test: same cosmology, same n(z), ξ± compared on our θ grid against a stated tolerance, σ8-vs-A_s amplitude convention settled inside the test
Not in scope: Smokescreen wiring, secret handling, blinded-COSEBIs derivation (PR 6).

Retired by the Smokescreen-fork replan (#241): sp_validation no longer installs firecrown — blinding calls the fork's theory-backend protocol with direct-CCL callables (#252, which also carries the CAMB↔CCL cross-check). Detached from #241 so the progress bar tracks live work only.
