`nifstreams` is the classic NIF streaming surface — global `pool`,
`PackedToken`, `next(s)` — that this compiler's IC modules (ast2nif,
deps, modulegraphs, pipelines) are written against. It lived in
`dist/nimony/src/lib` even though nimony's own code is under standing
orders never to import it, so nothing over there ever ran a line of it.
That is how it broke. Nimony's nifcore refactoring unified the token
kinds, and the adapter's `next` started returning `tagLitToken(...)` for
an opener — kind `TagLit`, not the `ParLe` its own header promises
structural scanners. Nothing in nimony noticed. Here, `deps.nim` walks
the import graph by testing exactly `t.kind == ParLe`, and the failure
has no error path: an opener it does not recognise is just an unknown
token, so it skips the subtree and reads on. Every `.deps.nif` still
"parsed"; the graph came out missing most of its edges. `nim c --ic:on`
then scheduled modules ahead of their imports and died on a `.s.bif`
nothing had written yet:
Error: nim m requires precompiled NIF for import: .../streams.nim
(expected: .../str6a47nh.s.bif)
`json`'s rule listed 5 of its 10 dependencies.
So the adapter moves into `compiler/`, where its one consumer lives, its
test runs, and its contract is ours to keep. `next` now emits a real
`ParLe`, with the tag id in the full 28-bit payload rather than
`TagLit`'s 9-bit field and a `tagId` shadowing nifpools' to match:
`globalTags` holds 355 tags before this compiler registers one of its
own dialect, and a 512-tag ceiling is not one this surface can live
under. The `when isMainModule` self-test states the promise; reinstating
`tagLitToken` fails it on the first assertion.
Everything the adapter adapts (nifpools, nifreader, lineinfos) still
comes from `dist/nimony` — only the adapter moved. With it here, the pin
can move to nimony master: `bif.load` there fills a loaded module's
pools with `addOrdered` instead of hashing every entry it just read back
in stored-id order.
Verified: `koch boot -d:release` reaches "executables are equal",
`testament cat ic` is 40/40, and a 67-module `--ic:on` build produces
`.c` files byte-identical to the old pin's. Interleaved on that build,
old pin 8.40/8.39/8.43 s vs new 8.17/8.14/8.14 s.
