M3's gate as named -- "remaining crud coverage; e2e3/e2e4 green" -- cannot
see this work. e2e3 and e2e4 contain zero positional paths, and the pinned
crud corpus covers `$[<identifier>]` only: no `$[]` case, no bare `$` case
anywhere in it. Both stayed green through a bug that replaced an array with
`{"$[i]": {...}}` and answered ok: 1. So M3 brings its own corpus, built the
way M2.5's was: inputs authored in `sources/`, every expectation recorded
from mongod 8.3.7, run through the shared runner with `--suite-dir`.
51 cases across the three spellings. It stands at 15 pass / 36 fail against
the refusal, which is the intended shape -- `expressions.json` was recorded
at 1 pass / 26 fail before the evaluator and is green now. The 15 that pass
are refusals where this server's code already matches; of the 36, 31 are the
constructs answering "not implemented" and 5 are refusals whose code
differs, four of them arrayFilters validation this server cannot do because
it never parses the option.
Every case records its `outcome`, refusals included. That is deliberate and
it is the whole point of the file: a refusal that left the document mangled
is indistinguishable from a clean one in `expectError` alone, and a mangled
document is what this corpus exists to catch.
What recording it settled, none of it guessable, the first contradicting
what the design review assumed:
- `y.$[i].c.$[i].d`, one identifier reused at two levels, is **accepted**
-- not a duplicate-identifier error
- `$[]` over an empty array is a no-op with modifiedCount 0
- `$[]` over an array with a non-document element is error 28, where every
other path failure here is 2
- a positional segment never creates: a missing or non-array path is an
error, where `$set: {'a.b': 1}` would construct one
- an upsert gets no special case -- it fails for the same reason
- `$` writes only the first matching element, and is refused when the query
never touched the array
- any of the three in first position is refused, as is `$` twice in a path
- `arrayFilters` alongside a replacement is ignored rather than refused
A case needing its own documents reseeds through operations rather than
`initialData`, because the format's `initialData` is per file and the runner
seeds it once per test. That keeps one file per operator instead of one file
per document shape.
crud scorecard unchanged at 204/87, aggregation corpus still 70/0.
