`S.set(item)` and `S.map(key, value)` are instance schemas (class `Set` / `Map`) that validate every item, key and value, so `S.minSize`/`S.maxSize`/ `S.size` are discoverable on them rather than reachable only through `S.instance` (IDEAS.md's first form-data bullet). Neither is JSON, so each also decodes from and encodes to its array wire form, the `S.date`/`S.uint8Array` shape: the decoder takes an array-typed source and the encoder answers an array target, so `S.array(item).with(S.to, S.set(item))` and its reverse both convert item by item. A failing Set item is located by its position (iteration follows insertion order) and a failing Map entry by its key. An async item accumulates into an array that `Promise.all` resolves into the container. Also drops `isAsync`/`hasTransform` in `copySchema`: they answer for one schema's decode direction, and the reverse getter copies, so `S.isAsync(schema)` used to make `S.isAsync(S.reverse(schema))` answer for the direction it never compiled — `specs/array-async.yaml` is the general regression (the set/map async specs hit it first). This generalizes the `delete mut.isAsync` that `S.transform` was doing for itself. Metrics: the two new exports cost 13.3 KB (`set`) and 13.3 KB (`map`) standalone; every other export moves by at most 9 bytes either way (98 shrink, 20 grow), and `pnpm spec check --perf` reports no significant change. Union fuzz is clean against HEAD. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HAvCFP11agzodUPYXtnGqf
`@schema type t = Set.t<string>` and `@schema type t = Map.t<string, int>` now emit `S.set(S.string)` and `S.map(S.string, S.int)`, alongside the `array`/`list`/`dict` cases they sit with. `Map.t` is the first built-in with two type parameters, so its arm has to precede the generic `Ldot` fallbacks that reject a second one; `Stdlib.`-qualified spellings are matched too, as the surface parsetree the ppx sees is whatever the source wrote.

`copySchema` runs on every `.with(…)`, and a `delete` there costs the fresh object its hidden class — the PR's perf run measured ~90% on schema creation across 95 targets. The reverse getter is the copy that actually inverts the direction those two caches answer for, and it runs once per schema and caches, so the drop belongs there. `S.transform` keeps doing its own. Also pins two behaviors the review asked about: - A codec on the item can make two distinct values encode alike, and then the container holds one of them — a Set collapses, a Map keeps the last entry. That is what a Set and a Map are (`["a", "a"]` in codec-array-set.yaml collapses with no codec in sight), so the specs pin it rather than the encoder rejecting it. - map-async now makes the *key* async too, which is its own path in the entry loop. It exposed a FIXME the spec now carries: a rejected async key reports no path, where a rejected async value — and a rejected sync key — report `["<key>"]`.

- **A union over two Maps silently dropped a member.** `items` means "the tuple slots of an array" to everything that pattern-matches a schema — union dispatch reads `properties || items` — so a Map whose key/value sat there looked like one 2-tuple case: `S.union([S.map(_, S.literal(1)), S.map(_, S.literal(2))])` compiled member 1 only and rejected `2`. The entry now hangs off `additionalItems` as an entry-tuple schema, where an array's item lives and where `reverse` already inverts it. Every source — wire array, Map, narrowed unknown — now describes its entries through the same field, which is what lets the three branches share one read. - **A size bound was checked against the rebuilt output, not the input.** `S.set(codec).with(S.minSize, 2)` rejected a valid 2-item Set whose items encoded alike. The pass-through source is now refined even with no checks of its own, as arrayDecoder does: an input-side check (a bound, reversed) only emits before the loop when the val it attaches to has a `prev`. - **Any array decoded to a Map.** `S.array(S.number).with(S.to, S.map(…))` compiled and read `undefined` out of every item at runtime; it is now an `unsupported_decode` at creation, like every other illegal conversion. - **A recursive item lost its error path.** The raise count is now sampled before the item parse, as arrayDecoder samples it: a recursive reference embeds its operation while the body is *built*, so a count read afterwards saw a pure body and skipped the path-prepending wrap. - **A rejected async Map key reported no path.** It hands its promise to `Promise.all` unwrapped, where the merge's own wrap only ever reaches the val it merges. Deletes the FIXME map-async.yaml carried. Also: an array source that needs no per-item work now rebuilds with `new Set(i)` / `new Map(i)` instead of an emitted `for…of` + `.add` loop, and set.ts drops an all-unknown early-out the generic path already covered (identical goldens either way). Metrics: generated code shrinks on every array↔container codec — the decode op of codec-array-set and codec-array-map 58 → 22 chars, codec-set-array 67 → 22, and −11% to −17% on their parse ops — against +12% and +16% on map-async's parse and decode for the key `.catch`. Bundle: `map` +123 bytes, `set` +8, every other export flat or smaller (`array` −2). `spec check --perf` reports no significant change, and the union fuzz is clean against origin/main on two seeds. New regressions: union2-map-literal, codec-set-date-minSize, map-minSize, codec-array-map-unsupported, set-recursive.

`S.isAsync(S.string)` — a probe of a *shared singleton*, from anywhere in a program — made every later `S.string.with(S.to, asyncSchema)` answer `false`, because `copySchema`'s `Object.assign` carried the cached `isAsync` onto the derived schema. A caller who trusts that answer reaches for `S.parser` and gets `invalid_operation` thrown at the async transform. `isAsync` and `hasTransform` are caches of one schema's decode direction, not part of what a schema describes, so they now get the treatment `r` and the operation cache already get: written non-enumerable, which is what keeps `Object.assign` from seeing them. That fixes every derivation at once — `.with(S.to, …)`, `.with(S.refine, …)`, `updateOutput`, and the reverse getter — and lets the two special cases that were patching this one derivation at a time go away (the deletes in the reverse getter from 70e51d3, and `S.transform`'s own `delete mut.isAsync`). Not `delete` in `copySchema`: that is the hidden-class deopt this PR already measured at ~90% on schema creation. Not an `= undefined` either — an always-present enumerable key is exactly what base.ts's enumerability note warns about. The regression is a test file rather than a spec: it needs two calls in a particular order (probe, then derive), where a spec's goldens are computed once per schema, and the schema that answered wrong never had a probe of its own. Metrics: +12 bytes on the median export (max +26, `json`), the cost of `defineProperty` over a plain store at each of the four write sites. Bought against a wrong answer that picks the wrong operation — DX over bundle size, per CLAUDE.md's priority order.

— | unchanged locally; CI-run only |
Measuring 5e44f72 against 0f8efe1 isolates it: the literal-* pair is unchanged between them, so those two moved when S.set/S.map first entered the bundle, not when the fixes landed.
What it is not: no code path either commit touches is reachable from S.literal("x") or S.instance(Set).with(S.minSize, 2). I tested the one mechanism that could act at a distance — the factories minting new hidden-class transition chains, which is what baseSchema's comment protects — by reordering the field writes in setFactory/mapFactory/entryFactory to match arrayFactory and date. It moved nothing (+63/+62/+40 after), so that hypothesis is out and I reverted the churn.
What is left is bundle growth shifting V8's decisions around the very cheapest measured operations — schema creation of a literal is a new plus a few stores, so a fixed sub-nanosecond shift reads as a large ratio. Consistent with that: membership is unstable across runs (record/array in CI, not locally), and every run and create+compile target — the ones that reflect actual parse/encode work — is unchanged, including all of S.set/S.map's own.
Flagging rather than fixing: I could not attribute it to a line, and the job is advisory by design. If you would rather the feature not carry it at all, the lever is bundle size — set is 13.3 KB and map 13.4 KB standalone — but that is a different change from this PR.

The `isAsync`/`hasTransform` leak needed two calls in a particular order, and landed on a different schema than the one probed — neither of which a spec can express, since it fixes one schema and computes its goldens once. CONTRIBUTING.md is where that kind of gap goes rather than reaching into `packages/spec`.

The membership is stable, the magnitudes are not, and a docs-only commit moves them as much as a source one. So these percentages measure the branch's bundle against main's, not the commit they are attached to — the per-commit attribution I tried to give earlier was reading more into them than they carry. The one delta that did survive commit-to-commit measurement is instance-set · create+compile +6.3% for the two defineProperty calls, which is real and bounded by compilation.
Everything that measures parse/encode work — every run and create+compile target, including all of S.set/S.map's own — is unchanged.

Three conflicts, all in code #356 (`S.to` custom codecs) redesigned: - `parse.ts` / `modifiers.ts` / `base.ts` / `advanced/recursive.ts` — resolved to main. My 985e676 made `isAsync`/`hasTransform` non-enumerable so no copy could inherit them; main has since deleted `S.isAsync` outright, and the spec harness now learns a direction's asyncness by *building* the op rather than probing a schema. That removes the reader whose wrong answer was the whole symptom, and main patches what remains where it can actually change — `to` drops both caches when a custom slot is attached, and `unionIsTransparent` skips them when counting fields. Keeping my mechanism on top would make both of those dead, for +12 bytes on every export and `instance-set · create+compile +6.3%`, to fix something no longer observable. `tests/directionCache_test.ts` goes with it: it probes an API that doesn't exist any more. The mechanism is in this PR's history at 985e676 if the stronger guarantee is ever wanted. - `specs/bundleSize.yaml` — regenerated. The `CONTRIBUTING.md` note about the harness gap goes too. Its subject was the ordered probe that leaked the cache, and neither the probe nor the leak survives #356 — a suggestion whose repro no longer exists is a claim nothing holds honest. `S.asyncDecoderAssert` is gone with #356, so the three async specs move to `S.to(…, { decode: { async }, encode: "auto" })`. Their encode side is now genuinely identity, which is what the goldens say. The async Map *key* path this PR fixed survives the port: a rejected key still reports `["<key>"]`. Verified on the merge: 4699 tests, 331 specs, a clean ReScript rebuild of all 104 modules (the `set`/`map` externals still compile), no `*.res.mjs` drift, and union fuzz clean against origin/main. Bundle 32167 → 33227 for the two new exports; no other export moves more than 5 bytes.

… catalog) Two conflicts, plus a port of set/map onto what #394's refactor established: - `builder.ts` — both sides appended after `B_nextConst`: kept `B_iterScope` (unchanged; `B_dynamicScope` and the canonical Val shape survive as-is) alongside main's new `B_readOnce`/`B_computed`. - `bundleSize.yaml` — regenerated. `set.ts`/`map.ts` now spell tag/val flags as bit literals — the refactor removed the named consts per the CLAUDE.md rule, and every symbol the two modules actually lean on (`B_mergeWithPathPrepend`, `B_asyncVal`, `B_markOutput`, `arrayFactory`, `arrayDecoder`, `_notVarBeforeValidation`) survives unchanged. The content axis (#394) never reaches an instance schema: a jsonString carrier chained through the wire form (`jsonString → array → set`) round-trips both directions. #393 also turned the union fuzzer into a cataloged compiled-vs-reference diagnostic, and its new test requires every export classified — `set` and `map` join as `wrap` members (`S.set(inner)` / `S.map(S.string, inner)`), so the fuzzer now generates them as union cases. On seed 1 no acceptance, reasons or exception-kind diff involves either: the count deltas against main's own run (which is red on this diagnostic by design) are the RNG stream shifting, and the one foreign-exception diff is `S.list`'s `.hd` walk on a non-list, present five times in main's run too. Goldens: map's ops pick up main's `!Number.isNaN(x)` → `x===x` codegen win (−1% to −4.5% chars). Verified: 5127 tests, 373 specs, clean ReScript rebuild of all 104 modules, no export but the two new ones moves more than 5 bytes (total 34016 → 35042).

One conflict, `bundleSize.yaml`, regenerated. The substantive port is #405: error paths are arrays now, and map.ts's async-key prepend had hand-inlined the old string form — the exact drift that copying a codegen shape invites. The prepend body is now `B_pathPrependCode`, shared by `B_mergeWithPathPrepend` and the one place that has to attach it to a promise the merge never reaches. Set indices arrive as numbers (`t[1]`, path `["t", 1]`), Map keys as what they were. Also rebuilt the previous merge commit: a `git stash` mid-merge had dropped MERGE_HEAD, so it had landed as a single-parent squash of main's four commits. Same tree, two parents now — otherwise every later merge would re-conflict on those files. Verified: 5340 tests, spec gate clean, ReScript rebuild of all 104 modules, union fuzz with no diff involving set or map. Bundle total 35453 → 36500; only the two new exports move.

A path holds strings and numbers, so an entry keyed by anything else (an object, a Date — every encode of a Map<Date, …>) is now located by its insertion position, as a Set item is; an array source counts by position too, matching the errors of its own validation loop. The counted loop moves into B_forOf, shared with set.ts. An array converts to a Map only when its item is exactly a `[key, value]` pair: `new Map` ignored a 3-tuple's third slot, then the reverse direction failed to compile. An async entry is one `Promise.all` chained after the value, so the merge's own catch names where either half failed and the prepend helper goes back to being inline in B_mergeWithPathPrepend; that returns every container export the bytes the helper cost. B_mergeWithCatch treats an append that turns out empty like no append, so a counted loop with nothing to count stays dead.

`S.set(asyncItem).with(S.minSize, 2)` bounded the promise: the decoder's refine ran on the val it returned, and parse's own `.then` continuation only wraps what follows. B_markOutput now puts the checks in a `.then` of their own when the val is async — which also fixes `S.array(asyncItem).with(S.minLength, 2)`, broken the same way.

… checks B_markOutput's async branch carried the checks on a B_refine it threw away, which had relinked `val.v` to it on the way; a copy carries them without touching `val`. The Map entry tuple goes back to the `sr` every tuple gets — flipping it changed no generated code. Comment wording and the docs' location rule now say what the code does, including that a key failing its own string check is reported as the key it is.

Implementation Details
Both schemas follow the container pattern established by
array:new Set(i)/new Map(i)rather than an emitted loopPromise.all(), then converted to the target typeS.tofor seamless codec compositionadditionalItems, neveritems— that field means "the tuple slots of an array" to union dispatch anddeepStrict, and a Map whose key/value sat there made two Map members of a union look like one caseFollow-up commits
Review of the first two commits turned up six defects, each fixed with a regression spec or test:
Maps silently dropped a member (theitemsissue above) —union2-map-literal.yamlS.set(codec).with(S.minSize, 2)rejected a valid 2-item Set —codec-set-date-minSize.yamlMap, failing at runtime instead of at creation —codec-array-map-unsupported.yamlset-recursive.yamlMapkey reported no path —map-async.yamlisAsync/hasTransformwere inherited throughcopySchema, soS.isAsync(S.string)made every laterS.string.with(S.to, asyncSchema)answerfalseand send the caller to a throwingS.parser—tests/directionCache_test.tsMetrics
Bundle:
set13.3 KB andmap13.4 KB standalone; total 31649 → 32728 bytes, of which +12 on the median export comes from the direction-cache fix. Generated code shrinks on every array↔container codec (the decode op ofcodec-array-set/codec-array-map58 → 22 chars).spec check --perfreports one attributable change,instance-set · create+compile +6.3%, for twodefinePropertycalls per compiled operation. The largercreatenumbers in the perf comments are not per-commit — a docs-only commit reproduces them; see this comment. Union fuzz is clean againstorigin/mainon two seeds.https://claude.ai/code/session_01HAvCFP11agzodUPYXtnGqf
