Program::of and Program::emit_reading of modules.rs into modules.nika (Part #125)Score: self-hosting lane, bootstrap lane 1 (docs/bootstrap.md). Plan row M3b of docs/selfhosting-plan.md, Large files 3 (draft 100 %, prerequisite M3a built in 1890fc9). S=2, C~3-5 M (comparable: M3a, P4b). Runs after MF (manifest.rs); different files, both add to the index lowered.rs, so serial.

The driver converts this before you start (.draft.nika, .notes, .rs): start from it. Ranges at 06eaea6; if git log shows a later change to modules.rs (MF should not touch it), re-grep fn of( and pub fn emit_reading(. The draft keeps method shape and Rust names (m3a: --prefix was not applied to functions; P5a kept 6 of 104 lines by keeping methods): the target is free functions modules_program_of and modules_emit_reading over a host; keep the bodies, redo signatures and calls.
If crates/nikaia-compiler/src exists, R0 (#921) has run: read crates/nikaia-std/src/tools as crates/nikaia-compiler/src, nikaia_std::tools:: as nikaia_compiler::.

Nikaia modules_emit_reading(host, packages: ref Vec[String?], shown: ref Vec[String], sources: ref Vec[String]) -> String throws holds the trust decision (keyed packages by last :: segment, both barrier rules), the header lines, the loop skipping dependency units, and the abort table.\n placement).project.rs, main.rs, parser/mod.rs, it tests map_ledger, map_seeds, map_trust, package_graph, dependency_ledger, result_source, examples, modules, accepted_compiles, accepted_sweep.crates/rs2nika/** (converter lane, uncommitted convert/nikaia.*), contracts/*, check/*, emit/* (lane 2), manifest.rs/manifest.nika (MF), docs/briefs/* other than your report.target/fast/nikaia to your scratch dir before a long test run; right before it, git status --short the lowered files (another session may rewrite them: m3a lost a round).it filters modules package map_ trust dependency result_source examples; nikaia test --project tests/compiler; lower-std fixpoint. --lib modules:: has no tests.modules_program_of, modules_emit_reading into modules.nika with doc comments; Program::of and Program::emit_reading forward. lower-std: only lowered/modules.rs (and the index if a name is new) changes.

Found: is only for a defect outside your change (it cuts the batch); a process event such as another session resetting or rewriting your files is no Found:, it goes under Needs: (m3a 2026-10-28); a converter draft that came out wrong is no Found:, it is one of the costliest edits under Rs2nika:, which the converter lane reads (e12-4b 2026-10-27); how you solved your own step goes into the commit message. Deviation: is only a step of the brief built otherwise than written or not built (a choice the brief left to you, such as keep what X needs and say so, is no deviation: it goes into the commit message; nor is building two steps in one commit when every step is built, e12-3a 2026-10-27, nor a step another commit on develop already built, shown by your test failing with that commit’s change reverted, b889 2026-10-27: name the commit in Body:, nor re-keying an allow-list entry (KNOWN) whose hash changed for the same program and the same reason, b-fixforward-sweep2 2026-10-28: say so in Body:); how you verified (e.g. a test not run against the unfixed compiler) goes under Tests:.
