+# OpenSpec Change: barrel-explicit-exports
+
+- **Change ID**: barrel-explicit-exports
+- **Scope**: cross-cutting — every package under `packages/*/`
+- **Status**: PROPOSED
+- **Date**: 2026-05-03
+- **Reference**: `openspec/AGENTS.md` §6a (Barrel exports — explicit named, not `export *`)
+
+## Summary
+
+Replace `export * from "./<feature>.js"` with explicit named re-exports in every per-feature `<feature>/index.ts` barrel across the monorepo. The package-root `src/index.ts` files are out of scope for this change — those keep `export *` for now and may be migrated to `export * as <name> from` namespace exports in a future change (also permitted under §6a). Generated selector indexes (`*.select/index.ts`) are also out of scope, since they are the one place §6a explicitly allows transparent forwarding.
+
+The motivation is direct from §6a: the public API of a feature module must be the contract the barrel declares, not whatever the source file happens to export today. `export *` silently leaks every new symbol added to the source, which (a) defeats reviewability, (b) makes accidental private-helper exposure trivial, and (c) blurs the documented surface area against the actual one. Tree-shaking is unaffected — `"sideEffects": false` rollup/esbuild treat both forms identically.
+
+## Scope
+
+**In:** 536 distinct `<feature>/index.ts` files across 70 packages, totalling ~875 `export *` lines (the remaining ~37 of the 912 total live in package roots / generated selectors / impl files).
+
+**Out:**
+- 21 package-root `src/index.ts` files (deferred to a follow-up change).
+- 14 `*.select/index.ts` generated selector forwarders (allowed by §6a).
+- 11 non-index impl files using `export *` (e.g. `aes-256-gcm.ts` forwarding to its `.select/` directory) — these are forwarder shims for the selector mechanism, not feature barrels.
+- 1 `.d.ts` third-party type stub.
+
+## Why one cross-cutting change instead of one per package
+
+This is a single mechanical rule application, not a design decision per package. The rule is already canonicalised in `openspec/AGENTS.md` §6a; there is nothing to negotiate per package. Splitting into 70 micro-proposals would inflate process overhead without changing what gets shipped or how it is reviewed. The per-package verification gate (§13: `lint typecheck test` + 100% coverage, plus dependent sweep on foundation packages) is preserved — the change is implemented one package at a time, gates run per package, and only after all 70 packages are green is the change archived.
+
+## Behavior change
+
+None. Every symbol that was reachable through `export *` remains reachable, with the same name and same type. Consumers continue to import via `import { X } from "@suaveplan/<pkg>/<feature>/<feature>"` exactly as before. The diff is barrel-internal: the barrel now lists the symbols by name instead of forwarding the whole module.
+
+The one observable difference is what does NOT happen any more — adding a new export to `<feature>.ts` will not auto-leak through the barrel. This is the intended invariant.
+
+## Verification per package
+
+For every package touched:
+
+1. `bunx turbo lint typecheck test --filter=@suaveplan/<pkg>` — green.
+2. `bunx turbo test:coverage --filter=@suaveplan/<pkg>` — 100/100/100/100.
+3. Foundation packages (`error`, `events`, `logger`, `validation`, plus `crypto-utils` since several primitive packages depend on it): also `bunx turbo test --filter=...@suaveplan/<pkg>` to catch dependent regressions.
+4. Banned-pattern scan and missing-`.md` scan re-run to confirm no incidental regressions.
+
+## Impact
+
+### Affected dependents
+
+Cross-cutting; every package in `packages/*/` is affected. Foundation packages enumerate their dependent sets via `bunx turbo ls --filter=...@suaveplan/<pkg>` per the §13 step 10 / §14a contract — those sweeps run per foundation package as it ships. For non-foundation packages, the per-package gate in step 1 above is sufficient (no dependents on a leaf package exist by definition).
+
+### Migration
+
+None for consumers. Internal-only refactor.
+
+## Spec delta
+
+`openspec/specs/monorepo-structure/spec.md` gains a `Barrel export form` requirement that codifies §6a as an enforceable spec scenario (so future packages cannot regress).

+## ADDED Requirements
+
+### Requirement: Barrel export form
+
+Per-feature module barrels (`src/<category>/<feature>/index.ts`) SHALL re-export their module surface using **explicit named re-exports**, not `export * from`. Package-root barrels (`src/index.ts`) MAY use `export * from` or `export * as <name> from` namespace exports until they are migrated under a separate change. Generated selector indexes (paths matching `*.select/index.ts`, plus per-impl-variant forwarders such as `*.native/index.ts` and `*.noble/index.ts` that contain only a single `export *` forwarder line) are exempt because transparent forwarding of the impl surface is the entire purpose of those files.
+
+The reasons match `openspec/AGENTS.md` §6a:
+
+- The barrel is the public contract; `export *` makes the contract whatever the source file happens to declare today.
+- Adding a new private helper to `<feature>.ts` must not auto-leak through the barrel.
+- Type-only re-exports remain clean (`export { type X }` per symbol).
+- Tree-shaking is equivalent under `"sideEffects": false` with rollup or esbuild — there is no bundle-size argument for `export *`.
+
+#### Scenario: Feature-module barrel uses explicit named exports
+
+- **WHEN** `src/<category>/<feature>/index.ts` re-exports the contents of `<feature>.ts`
+- **THEN** the barrel uses `export { Symbol1, type Type1, ... } from "./<feature>.js"`
+- **AND** the barrel does NOT contain a line starting with `export * from "./<feature>` (with or without the `.js` suffix)
+
+#### Scenario: Generated selector index exemption
+
+- **WHEN** `src/<path>/<primitive>.select/index.ts` exists for a per-primitive selector
+- **THEN** that file is permitted to contain `export * from "./<primitive>.select.js"`
+- **AND** its parent directory ends in `.select`
+
+#### Scenario: Namespace re-export at package root is permitted
+
+- **WHEN** `src/index.ts` re-exports a sub-namespace
+- **THEN** it MAY use `export * as <name> from "./<path>.js"` (namespace export)
+
+#### Scenario: Repository scan finds no banned barrel forms
+
+- **WHEN** `grep -rn '^export \* from' packages/ --include='*.ts' | grep -v '/dist/' | grep -v '/src/index.ts:' | grep -v '/.select/' | grep -v 'export \* as'` is run
+- **THEN** no line returned matches a `<feature>/index.ts` path AND every remaining line is in a `*.select/`, `*.native/`, or `*.noble/` forwarder index OR a non-`index.ts` impl file

+# Tasks — barrel-explicit-exports
+
+Per-package gate (§13): `bunx turbo lint typecheck test --filter=@suaveplan/<pkg>` + `bunx turbo test:coverage --filter=@suaveplan/<pkg>` must be green before ticking the package.
+
+Foundation packages additionally require `bunx turbo test --filter=...@suaveplan/<pkg>` (dependent sweep, §13 step 10).
+
+## Foundation layer (dep sweep required)
+
+- [x] `@suaveplan/error` — convert feature barrels; gate; dep sweep (202/204 pass; 2 unrelated to barrel — pre-existing `third-party-elevenlabs` missing `src/index.ts` scaffold)
+- [x] `@suaveplan/events` — convert feature barrels; gate; dep sweep (131/133 pass; same 2 pre-existing `third-party-elevenlabs`)

+- [x] Re-run global `grep -rn "^export \* from" packages/ --include="*.ts" | grep -v /dist/ | grep -v "/src/index.ts:" | grep -v "/.select/" | grep -v "export \* as"` — zero feature-barrel `<feature>/index.ts` matches remain. Remaining lines are 21 package-root `src/index.ts` files (deferred per scope) plus 5 non-index impl files (`types.ts`, `transform.ts`, `pack-iterator.ts`, `ed25519.ts`, third-party `.d.ts` stub) which are out of scope per this change.
+- [ ] Fold `specs/monorepo-structure/spec.md` delta into `openspec/specs/monorepo-structure/spec.md`.
+- [ ] Move `openspec/changes/barrel-explicit-exports/` → `openspec/archive/2026-05-03-barrel-explicit-exports/`.
+
+## Pre-existing failures observed (none caused by this change)
+
+These regressions existed on `genesis` before this change and persist after; flagged here so the next agent does not attribute them to barrel-explicit-exports:
+
+1. `@suaveplan/third-party-elevenlabs` — package has no `src/index.ts`; `vite build` fails with `Could not resolve entry module "src/index.ts"`. Scaffolded incompletely in the prior session.
+2. `@suaveplan/crypto-bin` — package's `build` script invokes `vite` but `vite` is not installed in the package's deps, so it falls through to `/usr/bin/bash: line 1: vite: command not found` (exit 127).
+3. `@suaveplan/crypto-hash` — `src/mac/argon2id-password/argon2id-password.ts:37` has a `pad === 0 ? s : s + …` ternary whose `pad === 0` branch is not exercised by tests; coverage drops to 99.19% (threshold is 100%). Test gap, not a barrel issue.
+4. `@suaveplan/crypto` — `tests/dep-graph.test.ts` asserts the runtime dep set is exactly `[…, "@suaveplan/events", …]` without `@suaveplan/bitpacker-crypto`, but `package.json` includes `@suaveplan/bitpacker-crypto`. Either the assertion needs to be updated to include the new dep or the dep needs to be removed; out of scope here.
