Codemod split: generate per-entry files and an index for spec conversions/registry.ts with a deterministic script

domain:devx#1 · os-support-ai · session_01WGufzgBDcBNVmSmo7VFHpj

Filing gate: ruling 6583399215 on #29465 (letter A, maintainer 「同意」 2026-11-02T17:11Z), whose exit stroke 6583664223 names one card per remaining file, filed into its lane by the domain:devx seat once the pilot #29520 merged. It merged as PR #29598 (d46b1ff23f, 2026-11-03T16:26Z). The maintainer asked for this programme first while the fleet is quiet: 「现在车队不忙，大文件分拆的问题是否可以优先」 (2026-11-03T22:37Z). ⛔ Not a claim. No grade: triage sets it and routes it.

Ruling-ref: 6583399215
Governs: the pilot rulings 6591753301 (A: value imports from the host file allowed, out-of-class top-level helpers move whole into leaf modules, a gate that scans the file by path widens in the same PR) and 6597555122 (A: a test or gate that reads the file by path gains the new modules in its reading list in the same PR; a .d.ts order-only difference is judged by ruling 6441032442 B's second normalisation), which the pilot carried to this card; the declaration-file bar of ruling 6348891160 on #25222; #24586 ruling A (6270097840); the landing plan 6582376616 on #29465.

Reader who acts: a domain:spec seat (the file is packages/spec), dispatching one dev.

What to build

A deterministic codemod for packages/spec/src/conversions/registry.ts (16,019 lines on main c92b8872). It is a table, not a class: the conversion entries ahead of CONVERSIONS_BY_MAJOR (line 15987) and ALL_CONVERSIONS (16016). Per ruling 6583399215 it splits into per-entry files plus a generated index, as Split migrations/registry.ts's two append tables into per-entry files (registry half of #6957's ruling) #7297 did for the migrations registry. The exported names, their order in CONVERSIONS_BY_MAJOR and ALL_CONVERSIONS, and every entry's text stay as they are.
The script's own proofs: byte-identity of every moved entry, the declaration bar of ruling 6348891160 judged by 6441032442's second normalisation, determinism, the arrays' contents and order equal at base and head (ALL_CONVERSIONS mapped to ids), and every gate, census or test that reads registry.ts by path widened in the same PR (retired-after.census.* and the authorable-surface and D3 gates are the first to check).
Type-check and the spec suite including test:repo at the base counts.

How it lands (landing plan 6582376616)

Phase 0, no pause: build and prove the codemod and its generated split in a draft PR. Nothing else on the file stops.
Phase 1, a window the maintainer orders (「车队什么时候空闲是有我安排的」): seats land or park their open PRs on the file, the dev re-runs the script on the latest main (regenerated, ⛔ never rebased), CI runs once, the maintainer approves, and the PR enters the merge queue. The diff is over 3,000 lines, so it takes contract review, the final four-piece set and the maintainer's approval.
⛔ The generated split is never hand-edited to pass. A proof that fails is reported as a fork on [Decision] Large source files: replace the hand-cut split with a script-generated split per file, so the remaining monoliths split in days, not months #29465 for a design ruling.

Done when

The draft PR holds the script and the generated split with every proof passing, and it has landed in the maintainer's window; or the fork is reported on #29465.

Re-measure: git show origin/main:packages/spec/src/conversions/registry.ts | wc -l; git log --since='7 days ago' --oneline origin/main -- packages/spec/src/conversions/registry.ts | wc -l.

Dedupe (open and closed): codemod, split in:title, 拆分, large file, 29465. Hits: #29465, #29520, #24586, #25467, #25522, #25521. None is a per-file codemod card for this file. New.

File surface: scripts/codemod-split-conversions-registry.mjs (or beside the pilot's script), packages/spec/src/conversions/registry.ts → per-entry files plus a generated index, every gate, census or test that reads registry.ts by path (widened in the same PR, per ruling 6597555122), the script's proof tests.
Container & model: L, mode:thread, model: TIER_DEFAULT, effort: high (the pilot #29520's tier)

Thread-read: 6583664223
Premise: holds. registry.ts is 16,019 lines at origin/main c92b8872 (3 commits in 7 days). The pilot #29520 landed as PR #29598 (d46b1ff23f, 16:26Z today). The domain:devx seat filed this card into the spec lane per exit stroke 6583664223.
Dispatch basis: the maintainer's 「现在车队不忙，大文件分拆的问题是否可以优先」 (2026-11-03T22:37Z) raises this programme ahead of the p1/p2-only rule while the fleet is quiet. Triage's first touch (grade) is still owed and is not pre-empted: this claim sets no priority:*.
Scope: Phase 0 of landing plan 6582376616 only, a draft PR with the codemod, the generated split and every proof. Phase 1 (regenerate on the latest main, land) waits for a window the maintainer orders; the PR is over 3,000 lines, so it needs the maintainer's approval.
Serial constraints cleared: none in flight on registry.ts from this seat; Phase 0 pauses nothing.

Landed: PR #29993 merged at merge commit d79eecfe. conversions/registry.ts is now split into per-entry modules by the codemod, under the maintainer's approval and freeze window. The card closes by Fixes, and the seat removes pm:dispatched.

Carried: the base-vs-base .d.ts build nondeterminism on main, measured during review, goes to a follow-up card. #29994 already covers the skill text and the MAJOR_18_CONVERSIONS docblock.
