+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## What this repo is
+
+A pnpm workspace holding two independently published CLIs plus the pyinfra
+deployment units one of them runs:
+
+| Path              | Package             | Binary   | Role                                                     |
+| ----------------- | ------------------- | -------- | -------------------------------------------------------- |
+| `packages/nopy`   | `@bitsquare/nopy`   | `nopy`   | interactive pyinfra script management and execution      |
+| `packages/keyman` | `@bitsquare/keyman` | `keyman` | SSH key management, shelling out to `age` / `ssh-keygen` |
+| `cubes/`          | —                   | —        | the deployment units `nopy` runs (not published)         |
+
+The root package is private; only `packages/*` ship. The two packages do not
+depend on each other.
+
+## Commands
+
+```sh
+pnpm install                 # also installs the git hooks via simple-git-hooks
+pnpm run build               # tsc --build across both packages (project references)
+pnpm run typecheck           # tsc --build --noEmit
+pnpm run lint                # biome check .          (lint:fix / lint:ci variants)
+pnpm test                    # vitest run, both packages
+pnpm run test:coverage       # vitest with the coverage gate
+pnpm run coverage:summary    # renders the last coverage run as a Markdown table
+```
+
+Single package / single test:
+
+```sh
+pnpm --filter @bitsquare/nopy run test tests/config.test.ts     # one file
+pnpm --filter @bitsquare/nopy run test -t "merges configs"      # by test name
+pnpm --filter @bitsquare/nopy run test:watch
+pnpm --filter @bitsquare/nopy run nopy                          # run the CLI from source via tsx
+pnpm --filter @bitsquare/keyman run keyman
+```
+
+`typescript` is the 7.x native compiler, so `tsc` *is* the fast one — there is no
+separate `tsgo` binary.
+
+## Verification gate
+
+`lint:ci` → `typecheck` → `test:coverage` is one gate, run in three places: the
+`pre-push` hook, `ci.yml` (non-`main`), and `publish-snapshot.yml` (`main`).
+`pre-commit` runs Biome with fixes on staged files only. Bypass with
+`SKIP_SIMPLE_GIT_HOOKS=1`; re-install after editing the hook config with
+`pnpm exec simple-git-hooks`.
+
+Coverage thresholds live in each package's `vitest.config.ts` (85 % branches and
+functions, 80 % lines and statements), not in a CI flag — they fail identically
+locally and on the runner. Barrel files (`src/index.ts`, `src/cubes/index.ts`,
+`src/nopy.cubes.ts`) and the Commander argv wiring (`src/*.cli.ts`) are excluded;
+adding logic to those files means moving it somewhere covered.
+
+Both packages set `pool: 'forks'` because tests use `process.chdir()` — most
+loader/config tests build a throwaway tree under `os.tmpdir()` and chdir into it,
+since discovery is driven entirely by the working directory.
+
+## nopy architecture
+
+One pass per invocation, `nopy.main.ts` orchestrating:
+
+1. **`nopy.config.ts`** — `loadConfig()` walks up from `process.cwd()` collecting
+   every `.nopyrc.json` plus `~/.nopyrc.json`, then merges them root-first.
+   Per-property strategy comes from the child's `resolution` block (`merge` is
+   the default: arrays concatenate and dedupe, objects deep-merge; `override`
+   replaces). Only properties listed in `PATH_PROPERTIES` (`cubeDirs`) get
+   relative paths resolved against their own config file's directory. **Throws**
+   if no config file exists anywhere — which is why `nopy.cli.ts` calls it lazily
+   inside the action, so `--help`/`--version` work outside a project.
+2. **`cubes/loader.ts`** — `findCubeDirectories()` unions `config.cubeDirs` with
+   every ancestor directory holding a `.npcubes` marker, then scans each
+   recursively (skipping dotted dirs and `node_modules`). A directory is a cube
+   when it holds both a manifest (`manifest.mjs` or `*.manifest.mjs`) and a
+   deploy script (`deploy.py` or `*.deploy.py`); manifests are loaded by dynamic
+   `import()`. Cube id = `manifest.id` → a `[id]` prefix in `manifest.name` →
+   the directory basename. Ids are flat and need not mirror the path
+   (`cubes/network/tailscale` declares `net:tailscale`). Duplicate ids and bad
+   manifests become entries in `errors`, which aborts the run.
+3. **`nopy.workflow.ts`** — picks interactive, file-replay, or history-replay and
+   normalises all three into a `WorkflowResult`. Replays never re-prompt except
+   for passwords (never persisted) and a missing host.
+4. **`cubes/dependencies.ts` → `BuildContext.resolveCube()`** — the core.
+   Recursive, per (cube, host): assign params and schema defaults → collect
+   variables (prompt, or read them back from the session on replay) → run
+   `before` hooks → resolve `manifest.dependencies(vars)` (dynamic: it receives
+   the *collected* variables) → emit the deploy call → run `after` hooks. There
+   is no separate topological sort; ordering falls out of the recursion, and a
+   `${cubeId}:${host}` set makes emission idempotent. Hooks get a `HookContext`
+   whose `exec(id, vars)` re-enters `resolveCube`, so a hook can pull in a cube
+   that is not a declared dependency.
+5. **`nopy.executor.ts`** — runs the built `pyinfra <host> -y --data K=V ... --chdir <cubeDir> <script>`
+   commands through execa with inherited stdio, sequentially, stopping at the
+   first failure unless `continueOnError`.
+
+### Variables
+
+`Variables` (`nopy.common.ts`) keeps three per-cube scopes plus one global bag.
+`get(id)` merges them lowest-to-highest: `global` (from config `env`) →
+`defaults` (Zod `.default()`, and recorded session values on replay) → `prompts`
+(what the user typed) → `params` (values passed by a dependency spec or hook).
+Every schema key is guaranteed present on the pyinfra side; pyinfra parses
+`--data` values itself, so `"true"` arrives as a bool and numeric strings as ints.
+
+### Cube contract
+
+A cube directory holds `manifest.mjs` + `deploy.py`; anything else in it is
+ignored by the loader but reachable from the script, which runs with the cube
+directory as its cwd. Manifests are ESM, import `cubes.Manifest` from
+`@bitsquare/nopy`, and declare `id`, `name`, a Zod `schema` (each field
+`.describe()`d — the description is the prompt label — and `.default()`ed), plus
+optional `dependencies`/`before`/`after`.
+
+**Gotcha:** those manifests resolve `@bitsquare/nopy` through ordinary Node
+resolution from the manifest's own directory. Nothing in this repo links the
+package into `cubes/` or `packages/nopy/cubes/`, so loading them fails with
+`ERR_MODULE_NOT_FOUND` until you link it (`pnpm --filter @bitsquare/nopy run
+link:local`, then `npm link @bitsquare/nopy` where you run from).
+
+## keyman architecture
+
+Much smaller: `keyman.cli.ts` (argv, plus a `--print-config` escape hatch) →
+`keyman.main.ts`, an inquirer menu loop dispatching to one module per operation
+(`list`/`copy`/`generate`/`encrypt`/`decrypt`). `keyman.config.ts` mirrors nopy's
+upward-traversal + `resolution` merge for `.keymanrc.json`, but validates the
+result with Zod and falls back to defaults instead of throwing. `VAULT_ROOT` in
+the environment beats the config file. Encryption shells out to `age` /
+`age-keygen` / `ssh-keygen`, which must be on `PATH`.
+
+## Releasing
+
+Tag-driven, one package at a time; see `README.PUBLISH.md`.
+
+- Push to `main` → `publish-snapshot.yml` publishes both packages to the Gitea
+  registry as `<version>-main.<run>.g<sha>` under the `main` dist-tag. The
+  version is set on the runner with `npm pkg set` and never committed.
+- `git tag <dir>-v<version>` (e.g. `nopy-v1.2.0` — the directory under
+  `packages/`, not the npm name) → `release.yml` publishes to Gitea *and* npmjs.
+  The tag chooses the package, `package.json` supplies the version, and the run
+  fails if they disagree. A prerelease version goes out as `next`, otherwise
+  `latest`.
+
+So: bump `packages/<pkg>/package.json`, land it on `main`, then tag that commit.
+
+## Known drift
+
+`logConfigToFlags()` is exported and tested but nothing feeds its output into the
+built pyinfra command, so `log.verbosity` / `log.debug` in `.nopyrc.json`
+currently have no effect. Treat `docs/REFACTORING.md` as a plan, not a record.

+# Documentation audit
+
+Every claim in the repository's Markdown was checked against the source it
+describes. Findings are grouped by *kind of divergence*, because the fix differs:
+a phantom feature needs a decision (build it or delete the docs), a wrong claim
+needs an edit, a gap needs prose.
+
+Severity is about what it costs a reader:
+
+- **🔴 broken** — following the documentation produces a wrong result or a crash.
+- **🟠 misleading** — the documentation states something the code does not do.
+- **🟡 gap** — the code does something real that no document mentions.
+
+Verified against the working tree at commit `fcc1817`. Line numbers are from that
+state.
+
+Findings closed since are marked **✅ … fixed** and keep their original text as
+the record of what was wrong. So far: §1.1 (`--use-defaults`), §2.2
+(`getDefaults()`), half of §2.1 (precedence), and one bullet of §6.4.

+
+## 1. Documented features that do not exist
+
+These are the same class of problem as the `--parallel` flag that was removed
+earlier: documented in detail, absent from the source.
+
+### 1.1 ✅ `-D, --use-defaults` does nothing — **fixed**
+
+> **Resolved.** The flag is now implemented; see `docs/REFACTORING.md` item 5.
+> `BuildContext.resolveCube` skips the prompts, `env` in `.nopyrc.json` outranks
+> the schema default so a non-interactive run can be configured, and a cube with
+> a variable nothing can fill aborts the run by name instead of deploying it
+> blank. The finding below is kept as the record of what was wrong.
+
+| | |
+|---|---|
+| **Docs say** | `README.md:291` "Install with defaults (no prompts for customization)"; `docs/API.md:39` "Skip variable prompts, use defaults"; `nopy.cli.ts:54` "Run cubes with default values without prompts" |
+| **Code does** | Nothing. |
+
+The option is threaded through four layers and then dropped. `nopy.cli.ts:95` →
+`nopy.main.ts:125` → `nopy.main.ts:174` → `BuildContext.options.useDefaults`
+(`cubes/dependencies.ts:35`), where it is **never read**. The only branch that
+skips prompting is `isSessionReplay` (`cubes/dependencies.ts:62`).
+`runInteractiveWorkflow` destructures only `useAuthKey` and ignores its
+`useDefaults` too (`nopy.workflow.ts:50`).
+
+Every documented `-D` invocation — including
+`nopy install -D --save-session automated-deployment.nopysession.json`
+(`README.md:226`), which is presented as the way to do an unattended run —
+prompts for every variable of every cube.
+
+```
+$ grep -rn "useDefaults" packages/nopy/src/
+nopy.workflow.ts:19    useDefaults?: boolean;      # declared
+nopy.main.ts:94        useDefaults?: boolean;      # declared
+nopy.main.ts:125       useDefaults = false,        # defaulted
+nopy.main.ts:158       { useDefaults, useAuthKey },# passed
+nopy.main.ts:174       useDefaults,                # passed
+nopy.cli.ts:95         useDefaults: options...     # passed
+cubes/dependencies.ts:35  useDefaults?: boolean;   # declared — and that is all
+```
+
+### 1.2 🔴 `-j, --json` produces no output on success
+
+| | |
+|---|---|
+| **Docs say** | `README.md:18` "**JSON output** for CI/CD integration"; `README.md:360-367` "Machine-readable JSON output for scripting and CI/CD integration"; `docs/API.md:573` |
+| **Code does** | Emits JSON **only** on failure. |
+
+`jsonOutput` reaches three places in `nopy.main.ts` (140, 150, 219) and none of
+them prints a result. It suppresses the config banner, prints
+`{success: false, errors}` when cube *loading* fails, and suppresses progress
+lines. The success path at `nopy.main.ts:226-236` returns the `NopyResult` object
+to the caller, and `nopy.cli.ts:107-110` inspects `result.success` without
+printing it.
+
+A CI job running `nopy install --json` gets pyinfra's inherited stdio and nothing
+machine-readable. The exit code is the only usable signal.
+
+Related: `--dry-run --json` prints the **text** plan, not JSON.
+`executeDeployCalls` calls `outputExecutionPlan(calls)` without the `asJson`
+argument (`nopy.executor.ts:172`), even though the function supports it
+(`nopy.executor.ts:110`).
+
+### 1.3 🟠 `log.verbosity` and `log.debug` have no effect
+
+Pre-existing known drift, recorded in `CLAUDE.md`, but the README still presents
+it as a working feature — two tables, a recommendation paragraph, and a slot in
+the config example (`README.md:127-130`, `143-163`).
+
+`logConfigToFlags()` (`nopy.config.ts:352`) is exported and has 8 unit tests, but
+nothing calls it. `buildDeployCall` (`cubes/dependencies.ts:105-124`) constructs
+the pyinfra argv without consulting `config.log` at all.
+
+This is live in the repo's own config: `packages/nopy/.nopyrc.json` sets
+`"verbosity": "trace", "debug": true` and gets neither.
+
+### 1.4 🟠 Manifest `env` property
+
+`README.md:14` lists "**Default values** with optional customization via manifest
+`env`". `env` was removed from `Manifest` — see `docs/REFACTORING.md` item 3, and
+the current interface at `cubes/types.ts:43-56`, which has `id`, `name`,
+`schema`, `dependencies`, `before`, `after` and nothing else.
+
+### 1.5 🟠 Topological sorting
+
+`README.md:11` ("Dependency resolution with **topological sorting**"),
+`README.md:25` ("Topologically sorts cubes based on dependencies") and
+`README.md:381` ("because cubes are topologically sorted") describe an algorithm
+that does not exist.
+
+There is no sort. `BuildContext.resolveCube` recurses depth-first and pushes each
+cube after its dependencies, with a `${cubeId}:${host}` set for idempotence
+(`cubes/dependencies.ts:43-100`, `105-143`). The ordering is a side effect of the
+recursion order.
+
+This matters beyond vocabulary: a topological sort detects cycles, and this does
+not. Two cubes that depend on each other recurse until the stack overflows —
+`resolvedCubes` is only consulted in `buildDeployCall`, which runs *after* the
+recursive call. `docs/API.md:160` still promises `Error` "if ... circular
+dependency detected".
+
+---
+
+## 2. Documented behaviour that differs from the code
+
+### 2.1 🟡 Variable precedence is wrong in both directions — **partly fixed**
+
+> **Half resolved.** `env` now outranks the Zod defaults, as documented — this
+> was a prerequisite for `--use-defaults` being configurable at all. The second
+> pair was deliberately left: dependency/hook params still outrank prompts. In
+> practice they do not compete, because `VariableAssignment` leaves out any key
+> a dependency already supplied, so the operator is never asked about it. The
+> README now describes that rather than the old claim.
+
+`README.md:107-113` stated:
+
+> **Priority order (lowest to highest):**
+> 1. Zod schema `.default()` values
+> 2. Global `env` from `.nopyrc.json`
+> 3. Accumulated variables from dependencies
+> 4. User prompts / session replay
+
+`Variables.get()` (`nopy.common.ts:33-39`) does:
+
+```typescript
+return {
+  ...this.global,             // 1. config env        (lowest)
+  ...this.defaults[id],       // 2. Zod defaults
+  ...this.prompts[id],        // 3. what the user typed
+  ...this.params[id],         // 4. dependency / hook  (highest)
+};
+```
+
+Two pairs are inverted, and both have consequences:
+
+- **Zod defaults beat `env`, not the other way round.** So `README.md:114` —
+  "allowing users to override them globally via `.nopyrc.json`" — is backwards.
+  Setting `"env": {"UPDATE": false}` cannot override a cube declaring
+  `.default(true)`; the `env` value is only visible for keys the schema does not
+  define. This is why `KEY_DIR` works in `packages/nopy/.nopyrc.json` (no cube
+  declares it) and why anything else would not.
+- **Dependency/hook parameters beat user prompts.** A value passed as
+  `[['user:add', {USER: 'deploy'}]]` silently overrides what the operator just
+  typed at the form. The docs promise the opposite.
+
+### 2.2 ✅ "Every key ... is guaranteed to be present on `host.data`" — not when a field lacks `.default()` — **fixed**
+
+> **Resolved.** `getDefaults()` falls back to a per-field read, so one required
+> field no longer wipes out the rest; `VariableAssignment` prompts for every
+> schema key rather than only the defaulted ones; and `--use-defaults` refuses
+> to deploy a cube whose required key nothing supplied. Verified against all 22
+> cubes in `cubes/`: 19 build a complete `-D` run, the 3 below abort by name.
+
+`README.md:99` states it outright; `README.md:105` claims defaults ensure "every
+cube has a predictable starting state".
+
+`Cube.getDefaults()` (`cubes/types.ts:106-112`) is:
+
+```typescript
+try {
+  return this.manifest.schema.parse({});
+} catch {
+  return {} as z.infer<Schema>;
+}
+```
+
+One field without a `.default()` makes `parse({})` throw, and the `catch`
+discards the defaults of **every other field in the cube**. `VariableAssignment`
+then iterates over that empty object and returns before prompting
+(`nopy.prompts.ts:175-181`), so the user is never asked. The cube deploys with no
+`--data` flags at all and every `host.data.X` is `None`.
+
+Three cubes in this repo are in that state today:
+
+| Cube | Field(s) without `.default()` | Result |
+|---|---|---|
+| `net:wifi:connection` | `SSID`, `PASSWORD` | no prompt, no `--data`, all 4 vars lost |
+| `service:autostart` | `APP` | no prompt, no `--data`, all 3 vars lost |
+| `user:edit` | `USER` | no prompt, no `--data`, all 4 vars lost |
+
+The failure is silent — no error, no warning, just a pyinfra run with an empty
+data set.
+
+### 2.3 🔴 `.describe()` before `.default()` loses the prompt label
+
+`CLAUDE.md` and the cube contract state that each schema field is `.describe()`d
+and "the description is the prompt label". `nopy.prompts.ts:184-185` reads it as:
+
+```typescript
+const zodType = schema[key];
+const description = zodType?.description || key;
+```
+
+In zod 4, `.default()` returns a `ZodDefault` **wrapper** that does not inherit
+`.description` from the type it wraps. Ordering therefore decides whether the
+label survives:
+
+```
+z.boolean().describe('Update package cache').default(false)   →  description undefined
+z.boolean().default(false).describe('Update package cache')   →  description preserved
+```
+
+The README's own manifest example (`README.md:67-68`) uses the losing order, so
+anyone copying it gets bare `UPDATE` / `PACKAGES` keys as prompt labels instead
+of the sentences they wrote. `docs/API.md:610` happens to use the working order —
+the two documents disagree, and neither mentions that it matters.
+
+15 of the 22 cubes in `cubes/` are affected; among them
+`net:tailscale` (all 4 fields), `runtime:nodevm` (all 4), `user:add` (all 4),
+`ssh:keygen` (all 4) and `admin:locale` (all 4).
+
+### 2.4 🟠 Session files claim `version` and `timestamp` fields
+
+`README.md:179-181` shows a session with `"version": "1.0.0"` and
+`"timestamp": "2025-10-13T10:30:00Z"`, and `docs/SESSION_FORMAT.md:305-306`
+declares both **required** in the `NopySession` interface. Every MJS example in
+that file sets them.
+
+`NopySession` (`nopy.session.ts:44-55`) has neither. `createSession`
+(`nopy.session.ts:183-197`) does not add them, `saveSession` writes the object
+verbatim (`nopy.session.ts:68-79`), and `loadSession`'s validation
+(`nopy.session.ts:146-155`) checks only `cubes`, `hosts` and `auth`. The
+repository's own `packages/nopy/example.nopysession.json` omits both — it does
+not match the format its own documentation prescribes.
+
+Consequence: a `version` field implies a compatibility check that does not exist.
+Nothing reads it, so an incompatible old session fails later and more obscurely
+than a version check would.
+
+### 2.5 🟠 Session filename convention does not match `listSessions()`
+
+The READMEs consistently use `*.nopysession.json` (`README.md:223`, `330`, `338`;
+`docs/DOCKER.md:54`; the shipped `example.nopysession.json`).
+`docs/SESSION_FORMAT.md` consistently uses `*.session.json` / `*.session.mjs`.
+
+`listSessions()` (`nopy.session.ts:173`) matches only the second form:
+
+```typescript
+.filter((file) => file.endsWith('.session.json') || file.endsWith('.session.mjs'))
+```
+
+`"my-deployment.nopysession.json"` does not end in `".session.json"`, so the
+file naming the README recommends is invisible to the function documented at
+`docs/API.md:430`. `loadSession` is unaffected (it switches on `.json`/`.mjs`),
+so this only bites the listing API.
+
+### 2.6 🟠 `docs/DOCKER.md` container name contradicts the file it points at
+
+`docs/DOCKER.md:35` and `:45`:
+
+> We explicitly name it `nopy-test-container` because the
+> `example.nopysession.json` is configured to target this specific container name.
+
+`packages/nopy/example.nopysession.json` targets `@docker/nopy-test-ubuntu` —
+the *image* tag from the build step, not the container name. Following the guide
+exactly produces a pyinfra run against a container that does not exist.
+
+(`packages/nopy/.nopyrc.json` does list `@docker/nopy-test-container` in `hosts`,
+so the guide was probably written against the config rather than the session.)
+
+### 2.7 🟠 `docs/HOOKS.md` — hook parameters are not validated
+
+`docs/HOOKS.md:48` describes the hook's second argument as "The final,
+**validated** variables for the current cube".
+
+`cubes/dependencies.ts:71` passes `this.variables.get(cubeId)` — a plain merge of
+the four scopes. `schema.parse()` is called in exactly one place,
+`Cube.getDefaults()` on an empty object, to extract defaults. Values from
+prompts, `env`, dependencies and hooks are never validated against the schema at
+any point in the pipeline. `coerceValue` (`nopy.prompts.ts:145-159`) type-coerces
+prompt input, which is not the same as validation and does not apply to the other
+three scopes.
+
+### 2.8 🟠 `docs/HOOKS.md` — dependencies can pass variables too
+
+The comparison table at `docs/HOOKS.md:83` says variable passing is
+"Inherited from env" for dependencies versus "Explicitly passed via `exec()`" for
+hooks, presenting explicit parameters as a hook-only capability.
+
+`DependencySpec` is `string | [id, variables?]` (`cubes/types.ts:23`) and
+`cubes/dependencies.ts:86-88` unpacks the tuple and forwards it into the same
+`params` scope that `exec()` writes to. The two mechanisms are identical in this
+respect; per §2.1 both outrank user prompts.
+
+### 2.9 🟠 nopy README installation section describes the wrong package manager
+
+`README.md:248-279` says "This package is part of a **yarn** workspace monorepo",
+then gives `yarn install`, `yarn workspace @bitsquare/nopy build`,
+`yarn workspace @bitsquare/nopy nopy`, and `yarn nopy`.
+
+The repo is a **pnpm** workspace: `packageManager: "pnpm@11.17.0"` in the root
+manifest, `pnpm-workspace.yaml`, a `pnpm-lock.yaml`, and every other document
+(root `README.md`, `README.PUBLISH.md`, `CLAUDE.md`) uses pnpm. There is no
+`yarn.lock`.
+
+The section is also the wrong content for the file. `README.md` is one of three
+files shipped in the npm tarball (`files: ["dist", "README.md", "LICENSE"]`), so
+this is what a reader sees on npmjs.com — build-from-monorepo instructions
+instead of `npm install -g @bitsquare/nopy`, which is what the root README and
+`README.PUBLISH.md:314` correctly tell people to run.
+
+### 2.10 🟠 keyman README: two operations missing, one operation invented
+
+`packages/keyman/README.md:90-96` lists four menu entries: List, Encrypt,
+Decrypt, Quit. The menu (`keyman.main.ts:54-61`) has six:
+
+```
+📋 List keys      📝 Copy public key      🆕 Generate key
+🔒 Encrypt keys   🔓 Decrypt keys         ❌ Quit
+```
+
+`Copy public key` and `Generate key` are undocumented — the latter being the only
+way to create a key inside the tool, which is why the Quick Start
+(`packages/keyman/README.md:33`) tells the user to shell out to `ssh-keygen`
+manually.
+
+Conversely `packages/keyman/README.md:11` advertises "🔄 Support for key
+rotation". There is no rotation anywhere: `grep -rn "rotat" packages/keyman/src/`
+returns nothing.
+
+`packages/keyman/README.md:93` also says encrypt takes keys "from `vault/tmp/`".
+`encryptKeys` (`keyman.encrypt.ts:12-22`) unions `~/.ssh` and `vault/tmp`, and
+offers both in the checkbox.
+
+### 2.11 🟡 Root README understates the coverage gate
+
+Root `README.md:57-58` describes "a hard **85 % branch** floor". Both
+`vitest.config.ts` files set four thresholds: branches 85, functions 85, lines
+80, statements 80. `README.PUBLISH.md:135` and `CLAUDE.md` both state all four —
+the root README is the odd one out, and it is the file a new contributor reads
+first.
+
+### 2.12 🟡 `docs/DOCKER.md` relative link is broken
+
+`docs/DOCKER.md:8` links `[README.md](./README.md)`, which resolves to
+`packages/nopy/docs/README.md` — nonexistent. It should be `../README.md`.
+
+---
+
+## 3. `docs/API.md` — systematic drift
+
+`docs/API.md` documents an earlier architecture. It is not a matter of
+individual stale lines: the two central type definitions, one whole module, and
+two of the documented functions describe code that no longer exists. Anyone
+building against this file writes code that will not compile.
+
+Recommendation: regenerate rather than patch.
+
+### 3.1 🔴 Functions that do not exist
+
+| Documented | Reality |
+|---|---|
+| `resolveDependencies(cubes, selectedCubeNames)` (`API.md:142-160`) | No such export. Resolution is `BuildContext.resolveCube` and returns nothing — it accumulates into `deployCalls`. |
+| `buildDeployCalls(cubeNames, hosts, context)` (`API.md:286-313`) | No such export. The entire "Builder Module" section, and its `BuildResult` interface, describes code replaced by `BuildContext` (`docs/REFACTORING.md` item 2). Still listed in the table of contents at `API.md:12`. |
+
+### 3.2 🔴 `Cube<Schema>` — wrong shape entirely
+
+`API.md:75-84` documents an interface with `key`, `dependencies: string[]`,
+`schema`, `defaults()`, `before`, `after`.
+
+`Cube` (`cubes/types.ts:88-113`) is a **class**: constructor `(manifest, dir,
+deployScript)`, getters `id` and `name`, method `getDefaults()`. Everything else
+lives behind `.manifest`. Not one documented member name is correct — `key` is
+`id`, `defaults()` is `getDefaults()`, and `dependencies`/`schema`/`before`/
+`after` are on `cube.manifest`, not on `cube`.
+
+### 3.3 🔴 `Manifest<Schema>` — wrong shape
+
+`API.md:92-100` documents `key`, `dependencies: string[]`, `defaults: () => ...`.
+
+`Manifest` (`cubes/types.ts:43-56`) has `id` (not `key`), no `defaults` member at
+all, and `dependencies` is a **function of the collected variables**:
+
+```typescript
+dependencies?: (variables: z.infer<Schema>) => DependencySpec[];
+```
+
+That signature change is the headline of `docs/REFACTORING.md` item 2. The
+`API.md` example at `:171` does use the function form, so the file contradicts
+itself two paragraphs apart. Both `Cube` and `Manifest` are additionally shown
+as generic over `z.AnyZodObject`, which zod 4 removed; the codebase defines
+`AnyObjectSchema` for exactly this reason (`cubes/types.ts:13`).
+
+### 3.4 🟠 Incorrect signatures and examples
+
+| Location | Documented | Actual |
+|---|---|---|
+| `API.md:486-492` | `saveConfig(data, local?)`, example passes `false` | `saveConfig(data, configPath?: string)` (`nopy.config.ts:323`). Passing `false` writes nothing useful. |
+| `API.md:481-484` | Search order `./nopyrc.json` then `~/.nopyrc.json` | Filename is `.nopyrc.json` (leading dot). Home is applied **first** (lowest priority, `nopy.config.ts:117-120`), all ancestors are collected and merged root-first, and the function **throws** when none is found (`nopy.config.ts:285-289`). The `resolution` merge strategy is not mentioned. |
+| `API.md:534-540` | `VariableAssignment(cube, env)` returning vars | `VariableAssignment(cube, variables: Variables)` returns `Promise<void>` and mutates the `Variables` instance (`nopy.prompts.ts:167`). The example's return value is always `undefined`. |
+| `API.md:321-331` | `runWorkflow(sessionPath, cubes, config, options?)` | Takes a fifth parameter `replaySession?: NopySession` (`nopy.workflow.ts:206-212`) — the entire history-replay path. |
+| `API.md:337-344` | `WorkflowResult.cubesWithDependencies` | Field is `selectedCubes` (`nopy.workflow.ts:31`). |
+| `API.md:202-209` | `DeployCall.dependencies: string[]` | `DependencySpec[]` (`nopy.executor.ts:27`) — and always `[]` in practice (`cubes/dependencies.ts:132`). |
+| `API.md:452-457` | `NopyConfig` with 4 fields | Missing `history` and `execution` (`nopy.config.ts:68-81`). |
+| `API.md:37-45` | 7 `NopyOptions` parameters | Missing `printOnly`, `replaySession`, `saveToHistory` (`nopy.main.ts:93-104`). |
+| `API.md:169-175` | `cubes.Manifest` example | Omits `id`, the field that determines the cube's identity. |
+
+### 3.5 🟡 Exported and undocumented
+
+Public API in `src/index.ts` with no `API.md` entry: the entire history module
+(`addToHistory`, `listHistory`, `getLastSession`, `getSessionById`,
+`clearHistory`, `removeFromHistory`, `loadHistory`, `saveHistory`,
+`getHistoryPath`, `formatHistoryList`, `HISTORY_FILE`, `DEFAULT_HISTORY_SIZE`,
+plus `HistoryEntry` / `SessionHistory`), `BuildContext`,
+`runSessionReplayWorkflow`, `getConfigPaths`, `findCubeDirectories`, `getCube`,
+`filterInternalVariables`, `separateEnvAndCubeVariables`.
+
+The CLI cheat-sheet (`API.md:554-578`) omits `-R`, `-H`, `-P`, `--no-history`,
+and the `history` / `clear-history` commands.
+
+`ManifestFactory` (`cubes/factories.ts:28`) is marked `@deprecated` but is not
+re-exported from `cubes/index.ts`, so it is unreachable dead code.
+
+---
+
+## 4. Undocumented behaviour
+
+### 4.1 🔴 Cubes in this repo cannot be loaded
+
+`CLAUDE.md` records the `@bitsquare/nopy` linking gotcha; the package README does
+not mention it at all, and the gotcha is incomplete.
+
+Cube manifests are loaded by dynamic `import()` from their own directory
+(`cubes/loader.ts:75`), so they resolve their imports through ordinary Node
+resolution from `cubes/…`. Nothing in the tree provides either dependency:
+
+```
+node_modules/@bitsquare/          → absent
+packages/nopy/node_modules/@bitsquare/ → absent
+cubes/node_modules/               → absent
+```
+
+`@bitsquare/nopy` is the documented half. **`zod` is the other half** — 20 of 22
+manifests `import { z } from 'zod'`, and that fails independently of the nopy
+link. Verified by loading every manifest with a resolver hook: with only
+`@bitsquare/nopy` mapped, 20 of 22 fail `ERR_MODULE_NOT_FOUND: zod`.
+
+Because `loadCubes` turns each failure into an `errors` entry and `nopy.main.ts:147-152`
+aborts when `errors.length > 0`, a fresh clone cannot run a single cube. Neither
+README mentions a setup step.
+
+### 4.2 🟠 The SSH password is printed in plaintext
+
+Not stated in any document, and it sits directly against the security notes at
+`README.md:217` and `:325` (which are narrowly about *storage*, and are correct
+as far as they go).
+
+`buildDeployCall` embeds the password in the command string
+(`cubes/dependencies.ts:112-113`):
+
+```typescript
+parts.push(`--user ${this.auth.username} --password ${this.auth.password}`);
+```
+
+That string is then:
+
+1. logged at debug level — `log.debug(\`Command: ${commandStr}\`)`
+   (`nopy.executor.ts:76`) — and the `nopy` logger is configured with
+   `lowestLevel: 'debug'` (`nopy.main.ts:41-44`), so it **prints to the console
+   on every deployment**;
+2. printed unmasked by `--dry-run` — `outputExecutionPlan` masks values whose key
+   contains "password" in the `--data` section (`nopy.executor.ts:134`) but prints
+   `call.command.join(' ')` verbatim one line earlier (`nopy.executor.ts:127`);
+3. passed through `execa({shell: true})` (`nopy.executor.ts:79`), making it
+   visible in the process list and, without quoting, vulnerable to shell
+   metacharacters in the password.
+
+### 4.3 🟠 History and session files record only prompted values
+
+`README.md:414` says an entry records "the variable values that were answered at
+the prompts" — accurate, but the consequence is not drawn out.
+`buildDeployCall` records `this.variables.get(cubeId, 'prompts')`
+(`cubes/dependencies.ts:138`) — the prompts scope alone. Values that came from a
+dependency spec, a hook's `exec()`, `env`, or a schema default are **not** in the
+entry.
+
+Combined with §2.1 (dependency params outrank prompts) this means a replay can
+legitimately produce a different command than the run it replays, if the
+dependency graph resolved differently.
+
+### 4.4 🟡 `-P, --print-only` is undocumented
+
+Implemented (`nopy.cli.ts:61`, `nopy.main.ts:202-213`), listed in the CLI's own
+help examples (`nopy.cli.ts:38`), and absent from `README.md` and `docs/API.md`.
+It prints the built pyinfra commands grouped by cube and exits.
+
+Worth documenting alongside `--dry-run`, since the difference is not obvious:
+`--print-only` returns a `NopyResult` with `successful: 0` and skips execution
+entirely, while `--dry-run` goes through the executor.
+
+### 4.5 🟡 `--save-session` is ignored during a replay
+
+`nopy.main.ts:191` guards with `saveSessionPath && !workflow.isReplay`, so
+`nopy install -R -s out.json` writes nothing and says nothing. The
+"Recording a Session" section (`README.md:219-227`) does not mention it.
+
+### 4.6 🟡 `.npcubes` is documented but unused in this repo
+
+`README.md:43` shows a `cubes/.npcubes` marker in the layout diagram and
+`README.md:244` documents the mechanism. `find . -name .npcubes` returns nothing
+— discovery here runs entirely off `cubeDirs` in `.nopyrc.json`. The feature
+exists in `findCubeDirectories` (`cubes/loader.ts:26-30`); the diagram just shows
+a file that no reader will find if they go looking.
+
+### 4.7 🟡 `ssh:keyman` depends on a global `env` value
+
+`cubes/ssh/keyman/deploy.py` reads `host.data.get('KEY_DIR')`, which no manifest
+declares — it comes from `env` in `.nopyrc.json`. This works (§2.1: `env` is
+visible for keys the schema does not define) and it is the only cube relying on
+the mechanism, but nothing documents the coupling. Anyone running that cube from
+a project without `KEY_DIR` in their config gets `None`.
+
+---
+
+## 5. Cube documentation
+
+Two cubes have **no README at all**: `cubes/admin/hostname` and `cubes/git/clone`
+(20 of 22 have one).
+
+### 5.1 🔴 `cubes/service/autostart/README.md` documents a different cube
+
+The file is titled **"TypeStack Install Cube"** and describes cloning a git
+repository, `yarn install`, `yarn build`, `docker compose up -d`, and PM2 process
+management. The manifest (`service:autostart`, "Manage systemd service
+autostart") does none of that — it has three fields and calls `systemd.service`.
+
+| README documents | In the schema? |
+|---|---|
+| `USER` | ❌ |
+| `REPO` | ❌ |
+| `ENV` | ❌ |
+| `NODE_PATH` | ❌ |
+| `APP` | ✅ |
+| `AUTOSTART` | ✅ |
+| — | `SERVICE_NAME` (undocumented) |
+
+Every "Requirements" entry (Git, Yarn, Docker, PM2, NVM, SSH keys) is inapplicable.
+It reads as a leftover from a cube that was split or renamed.
+
+### 5.2 🟠 `cubes/network/wifi/access-point/README.md` — four wrong parameters
+
+| README | Manifest |
+|---|---|
+| `NETWORK_DEVICE` (default `wlan0`) | does not exist |
+| `CHANNEL` | does not exist — **but `deploy.py` reads it** (see §6.3) |
+| `IP_ADDRESS` (default `192.168.50.1`) | field is `AP_IP`, default `192.168.4.1` |
+| `CONNECTION_NAME` default `net:wifi:ap` | default is `pi-point` |
+| SSID / PASSWORD listed as "Required" | both have defaults (`PiPoint` / `1223334444`) |
+
+Both worked examples set keys that will be ignored.
+
+### 5.3 🟠 Two cubes claim to have no parameters
+
+| Cube | README says | Schema has |
+|---|---|---|
+| `cubes/runtime/docker` | "This cube currently has no configurable parameters." | `DISTRO` (`ubuntu` \| `debian`) |
+| `cubes/runtime/nodevm` | "This cube currently has no configurable parameters." | `VERSION`, `USER`, `ALIAS`, `GLOBAL_PACKAGES` |
+
+`nodevm`'s README also describes installing "the latest LTS via the official
+NodeSource setup script", while the manifest is named "Install nvm and nodejs
+with global packages" and takes an explicit `VERSION`.
+
+(`admin/cockpit` and `armor/fail2ban` make the same claim and are correct — both
+have empty schemas.)
+
+### 5.4 🟡 Cube id conventions are inconsistent
+
+- `cubes/caddy/base` declares `id: 'caddy'` while its sibling declares
+  `caddy:spa`. Every other nested cube uses the `group:name` form.
+- `net:wifi:connection` sets `name: 'network:wifi:connection - Connect to a WiFi
+  network'` and `user:edit` sets `name: 'user:edit - Modify an existing user
+  account'` — the id is baked into the display name. Since the picker renders
+  `${cube.id} - ${cube.name}` (`nopy.prompts.ts:43`), these show as
+  `net:wifi:connection - network:wifi:connection - Connect to a WiFi network`.
+  `README.md:54` documents `[id]`-in-name as a *fallback* for a missing `id`
+  field, not as a prefix to carry alongside one.
+
+---
+
+## 6. Defects found while verifying
+
+Not documentation issues, but found while checking the docs and worth recording.
+
+### 6.1 🔴 `cubes/service/autostart/deploy.py` cannot run
+
+```python
+from pyinfra.operations import systemd     # `server` is never imported
+from pyinfra import host
+
+APP = host.data.APP                        # AUTOSTART and SERVICE_NAME never read
+
+if AUTOSTART:                              # NameError
+    ...
+    server.shell(...)                      # NameError, in the else branch
+```
+
+`AUTOSTART` and `SERVICE_NAME` are declared in the manifest and never pulled off
+`host.data`; `server` is used but not imported. The script raises `NameError` on
+the `if`. Per §2.2 this cube also gets no `--data` at all, so it fails twice over.
+
+### 6.2 🔴 `-H <id>` and `--no-history` share one destination
+
+Both options write to `options.history` (`nopy.cli.ts:57` and `:64`). Verified
+with Commander:
+
+```
+argv=[]                             -> {}                        # undefined → saves
+argv=["--no-history"]               -> {"history":false}         # correct
+argv=["-H","abc123"]                -> {"history":"abc123"}      # correct
+argv=["-H","abc123","--no-history"] -> {"history":false}         # id destroyed
+```
+
+In the last case the `-H` argument is silently discarded and nopy falls through
+to a full interactive run instead of replaying. `saveToHistory: options.history
+!== false` (`nopy.cli.ts:104`) works only because the two meanings happen not to
+collide in the common cases.
+
+### 6.3 🟠 `access-point/deploy.py` reads an undeclared variable
+
+`host.data.get('CHANNEL')` — no manifest declares `CHANNEL`, so it is always
+`None`. The README documents it as a supported optional parameter (§5.2). One of
+the three has to give.
+
+### 6.4 🟡 Debug output left in the shipped code
+
+- ~~`nopy.common.ts:22` — `console.log('Assigning', artefactId, scope, values)`
+  fires on every variable assignment, printing values to the console. Combined
+  with §4.2 this is a second path by which secrets reach stdout.~~ **Removed**
+  alongside the `--use-defaults` work; it would have made an unattended run
+  unreadable. The two other paths in §4.2 are untouched.
+- `keyman.encrypt.ts:19-20` — `console.log(tmpKeys); console.log(sshKeys);`
+  before the prompt.
+
+### 6.5 🟡 No cycle detection
+
+Covered under §1.5. `docs/API.md:160` documents the error; there is no code that
+raises it. Mutually dependent cubes recurse until the stack overflows.
+
+---
+
+## 7. Checked and accurate
+
+Recording what was verified and found correct, so a future pass need not redo it.
+
+- **`README.PUBLISH.md`** — checked against `.gitea/workflows/*.yml` and both
+  manifests. Workflow triggers, the `files` array, dist-tag rules, the snapshot
+  version format, `upload-artifact@v3`, `cache@v4`, the `npm pack --dry-run`
+  step, `retention-days: 7`, and all four coverage thresholds are right. The
+  only file that states the coverage gate completely.
+- **Root `README.md`** — pnpm/corepack, Node ≥ 22 with `.nvmrc` pinning 24, the
+  script table, and both git hooks match the root `package.json`. Only the
+  coverage line is incomplete (§2.11).
+- **`CLAUDE.md`** — accurate throughout, including the `logConfigToFlags` drift
+  note and the resolution/merge description. Two additions worth making: `zod` is
+  missing from the cube-linking gotcha (§4.1), and `-D` being a no-op (§1.1)
+  belongs under "Known drift".
+- **`README.md` history section** (`:392-429`) — the recording rules, the
+  fail-then-`-R` flow, replay-does-not-re-record, the four suppression cases, the
+  `defaults`-layer replay semantics, and the `Cube not found` failure mode all
+  check out against `nopy.history.ts`, `nopy.main.ts:195-200` and
+  `cubes/dependencies.ts:62-69`.
+- **`README.md` continue-on-error section** (`:369-390`) — fail-fast, no
+  rollback, skipped-cubes-absent-from-results, exit code 1, and CLI-over-config
+  precedence match `nopy.executor.ts:180-193` and `nopy.cli.ts:67-68`.
+- **`README.md` cube layout and discovery** — the directory-pair rule, recursive
+  scan, dotted/`node_modules` skipping, the prefixed `*.manifest.mjs` fallback,
+  and the three-step id resolution match `cubes/loader.ts` exactly.
+- **pyinfra `--data` type coercion** (`README.md:101`) — correct.
+- **keyman config** — priority (`VAULT_ROOT` > file > defaults), the four default
+  values, and the vault layout match `keyman.config.ts` and `keyman.encrypt.ts`.
+
+---
+
+## Suggested order of attack
+
+**1 — ~~Decide on the three phantom features.~~ Two left.** §1.1 (`-D`) is
+**done** — implemented, tested, and verified against every cube in `cubes/`.
+That closed §2.2 and half of §2.1 with it, since neither could be left standing
+under a run that never prompts. §1.2 (`--json`) and §1.3 (`log.*`) are still
+"documented, wired up, never read": each is a small implementation or a small
+deletion, but neither can stay documented as working.
+
+**4 — Decide the `.describe()`/`.default()` ordering (§2.3).** Either read
+through the `ZodDefault` wrapper in `nopy.prompts.ts`, or fix the ordering in all
+14 manifests and the README example. The first is one line and cannot regress.
+
+**5 — Regenerate `docs/API.md` (§3).** Too far gone to patch: two core types,
+one whole module, and two functions describe code that no longer exists.
+
+**6 — Cube docs (§5) and the two missing READMEs.** `service/autostart` is the
+worst — its README belongs to a different cube, and its `deploy.py` does not run
+at all (§6.1).
+
+**7 — Secrets on stdout (§4.2, §6.4).** The `console.log` in `Variables.assign`
+is gone. Still open: mask the password in the executor's debug line and in the
+dry-run plan, and pass `--user`/`--password` as argv rather than interpolating
+into a shell string.

 Nopy wraps pyinfra with structure, validation, and an interactive experience for managing complex infrastructure deployments. It organizes deployments into self-contained "cubes" with dependency management, schema validation, and lifecycle hooks.

+## Features
+
+- **Dependency resolution** with topological sorting
+- **Before/after hooks** for multi-cube orchestration
+- **SSH key or password authentication**
+- **Default values** with optional customization via manifest `env`
+- **Schema validation** using Zod
+- **Recursive cube directory discovery**
+- **Dry-run mode** for previewing deployments
+- **JSON output** for CI/CD integration
+- **Session history** with replay capability
+
+## Workflow
+
+1. **Load cubes** - Discovers and validates cubes from configured directories
+2. **Interactive prompts** - Select cubes, target host, and authentication method
+3. **Dependency resolution** - Topologically sorts cubes based on dependencies
+4. **Variable assignment** - Validates and collects configuration with schema validation
+5. **Execute hooks** - Runs before/after hooks for orchestration
+6. **Deploy** - Sequentially executes pyinfra commands

 ## Core Concepts

 ### Cubes

-Self-contained deployment units consisting of:
+A cube is a **directory** containing two files:

- **Python deployment script**: `<cube-name>.deploy.py`
- **JavaScript manifest**: `<cube-name>.manifest.mjs` defining schema, dependencies, defaults, and hooks
- **Configuration variables**: Validated with Zod schemas
+- **JavaScript manifest**: `manifest.mjs` defining schema, dependencies, defaults, and hooks
+- **Python deployment script**: `deploy.py`, a plain pyinfra script
+
+Configuration variables are declared in the manifest and validated with Zod schemas before the deployment script runs.
+
+```
+cubes/
+├── .npcubes
+└── apt/
+    └── install/
+        ├── manifest.mjs
+        └── deploy.py
+```
+
+Any directory holding both files is treated as a cube, so cubes can be nested as deeply as you like to group them by topic. Discovery is recursive; directories starting with `.` and `node_modules` are skipped. Additional files in the cube directory (a `README.md`, config templates, and so on) are ignored by the loader and can be referenced from the deploy script — the script runs with its cube directory as the working directory.
+
+The prefixed forms `<cube-name>.manifest.mjs` and `<cube-name>.deploy.py` are also still recognized, but plain `manifest.mjs` / `deploy.py` is the current convention.
+
+A cube's identity comes from the manifest's `id` field (see below). If `id` is omitted, nopy falls back to an `[id]` prefix in the manifest `name`, and finally to the directory's own name. Note that the id does not have to mirror the folder path — `cubes/network/tailscale` declares `id: 'net:tailscale'`.

 #### Cube Manifest

 import { z } from 'zod'

 ```

+#### Deployment Script
+
+The matching `deploy.py` is a plain pyinfra script. Nopy passes each schema variable to pyinfra as `--data KEY=value`, so they are available on `host.data`:
+
+```python
+from pyinfra import host
+from pyinfra.operations import apt
+
+UPDATE = host.data.UPDATE
+PACKAGES = str(host.data.PACKAGES).split(' ')
+
+apt.packages(
+    name='Install essential packages',
+    packages=['ca-certificates', 'gnupg', 'lsb-release'],
+    update=UPDATE,
+    _sudo=True,
+)
+
+apt.packages(
+    name='Install custom packages',
+    packages=[p.strip() for p in PACKAGES if p],
+    update=UPDATE,
+    _sudo=True,
+)
+```
+
+Every key defined in the manifest `schema` is guaranteed to be present on `host.data` — either from the Zod `.default()`, from `.nopyrc.json`, from a dependency, or from a user prompt.
+
+**Value types**: pyinfra parses `--data` values before your script sees them. `"true"` / `"false"` become booleans, numeric strings become `int`, valid JSON becomes the parsed structure, and everything else stays a string. This is why `UPDATE` can be handed straight to pyinfra's `update=` argument, while `PACKAGES` is wrapped in `str(...)` before splitting.
+
 #### Variable Defaults

 Variable defaults are defined directly in the Zod schema using `.default()`. This ensures that every cube has a predictable starting state and provides type-safe default values.

+The recording happens before the deploy commands run, so a **failed** deployment is recorded too — `-R` is the quick way to retry one after fixing the cause. Replaying a session with `-R` or `-H` does not itself create a new entry, so repeating never pushes the original run out of the list.

-**View deployment history**:
+**Default behaviour (fail-fast)**: without this flag, nopy stops at the first cube that fails. Cubes are deployed sequentially in dependency order, so the failing cube's output is the last thing you see — every cube still queued behind it is skipped entirely and is never attempted.
+
+This is deliberate: because cubes are topologically sorted, a cube that fails is often a dependency of the ones after it, and continuing would deploy them onto a half-configured host.
+
+Two consequences worth knowing:
+
+- **Cubes that already succeeded are not rolled back.** The host is left in a partial state — the cubes before the failure are applied, the rest are not. Fix the cause and re-run; well-written cubes are idempotent, so re-applying the earlier ones is normally harmless.
+- **Skipped cubes are not reported as failed.** They are simply absent from the results, so a summary of "3 successful, 1 failed" out of 6 cubes means the remaining 2 were never run.
+
+Either way, the command exits with code `1` if any cube failed, which is what CI picks up. Use `--continue-on-error` when your cubes are genuinely independent and you would rather collect every failure in one run than stop at the first.
+
+The default can be flipped for a project by setting `execution.continueOnError` in `.nopyrc.json`; the CLI flag takes precedence over it.

+History is what makes [Repeat last run](#basic-commands) work, but it holds more than just the last deployment: every recorded run stays replayable until newer runs push it out. `nopy history` (alias `nopy h`) lists them newest first, with `→` marking the entry that `-R` would replay:

+```
+
+Each entry records the selected cubes together with the variable values that were answered at the prompts, the target hosts, the authentication method, and the username — never the password. Pass an ID to `-H` to run that exact combination again:
+
+```bash
+nopy install -H mdk0zzp8b71cq
+```
+
+A replay is non-interactive: cube selection, host, and variable values all come from the entry, so nopy runs straight through without asking anything. The two exceptions are password authentication, which always re-prompts, and an entry with no recorded host, which falls back to the host picker.
+
+Two things are worth knowing before relying on an older entry:
+
+- **Recorded values are applied as defaults, not as a frozen snapshot.** If a cube's schema has gained a variable since the run was recorded, the replay neither prompts for it nor fails — the new variable quietly takes its Zod `.default()`. Global `env` values are likewise read from the *current* `.nopyrc.json` rather than from the entry.
+- **A replay fails if a cube no longer exists.** Renaming or deleting a cube id makes every history entry that referenced it unreplayable: nopy logs `Cube from session not found` and then aborts with `Cube not found: <id>`.
+
+The history lives in `.nopy.history.json` in the working directory and uses the same structure as a session file, so trimming the array by hand is a perfectly good way to prune it. It does contain the variable values that were entered, which is why it is listed in this repository's `.gitignore` — treat it like any other file holding deployment configuration. A corrupt or unreadable history file is treated as empty rather than raising an error, which looks exactly like a project that has never been deployed from.
+
+For a run you want to keep indefinitely, don't rely on history — it rotates. Use `--save-session` to write it to a file you control (see [Session Recording and Replay](#session-recording-and-replay)).

+# Cube bundles as npm packages
+
+Status: **Phase 0 has landed; Phases 1–6 are still a plan, not a record.**
+
+Distributing cubes as npm packages so a project can `pnpm add @acme/cubes-net`
+and have its cubes show up in `nopy` alongside local ones.
+
+## Goals
+
+- A cube bundle is an ordinary npm package, publishable to npmjs or Gitea
+  through the existing release lanes.
+- A consuming project opts into a bundle explicitly, by name, in `.nopyrc.json`.
+- Existing manifests, dependency specs (`dependencies: () => ['apt:essentials']`)
+  and stored session history keep working untouched.
+- The in-repo `cubes/` tree becomes the first published bundle, proving the path.
+
+## Non-goals
+
+- Automatic discovery of bundles from the dependency tree. Cubes run privileged
+  deploy scripts against real hosts; a transitive dependency contributing one
+  silently is a supply-chain hole. Opt-in per package, always.
+- Namespacing or id rewriting. Ids stay flat and global (see *Decisions*).
+- Version compatibility checks between a bundle and the `nopy` running it.
+  Noted as a risk, deferred.
+
+## Decisions
+
+| Question | Decision |
+| --- | --- |
+| Duplicate cube ids across sources | **Hard error.** No precedence, no shadowing. Mitigation is a good error message, not a fallback. |
+| Id format | Unchanged, flat. The id is the session key (`dependencies.ts:135`); changing it breaks `--repeat-last` and `--history`. |
+| Discovery | Explicit `cubePackages` list in `.nopyrc.json`. |
+| Migrate in-repo `cubes/` | Yes — `packages/cubes-core`, as the proof of concept. |
+| Split an authoring package (`@bitsquare/nopy-cube`) | **Yes.** Bundles take a regular dependency on it; `@bitsquare/nopy` re-exports it for backwards compatibility. See *Phase 4*. |
+
+## Current state
+
+What already works, unchanged:
+
+- `--chdir <cubeDir>` (`nopy.executor.ts`) means a `deploy.py` under
+  `node_modules` runs fine; pyinfra only needs the path.
+- `scanDirectory` skips `node_modules` when *descending* (`loader.ts:101`), not
+  for the root it is handed. So `"cubeDirs": ["./node_modules/@acme/cubes-net/cubes"]`
+  works today. That is the escape hatch until this lands, and it stays working
+  afterwards.
+
+What blocks a clean story:
+
+1. **Manifest imports.** `manifest.mjs` does `import { cubes } from '@bitsquare/nopy'`,
+   resolved by ordinary Node resolution from the manifest's own directory. From
+   inside `node_modules/@acme/cubes-net/`, that resolves upward into the
+   consumer's `node_modules` — fine if the consumer installed `@bitsquare/nopy`,
+   `ERR_MODULE_NOT_FOUND` if `nopy` is only installed globally. Same gotcha
+   CLAUDE.md already documents for the local `cubes/` tree.
+2. **No way to name a package** in config, only paths.
+3. **Recursively scanning `node_modules` is not a workaround.** pnpm symlinks
+   direct deps, and `readdir(withFileTypes)` reports a symlink as
+   `isSymbolicLink()`, not `isDirectory()` — the scan would skip every package.
+   Package roots must be resolved explicitly.
+
+## Phase 0 — fixes that land first — **done**
+
+Independent of packaging, and the duplicate-id work depends on them.
+
+**0.1 `scanDirectory` drops subtrees on duplicates.** `loader.ts:84-87` pushed
+the error and `return`ed, which exited before the recursive descent at line 100.
+Cubes nested below a duplicate never got scanned, so the error report was
+incomplete: you fix one collision, re-run, find the next.
+
+**0.2 Duplicate detection is order-dependent.** `loadCubes()` ran `Promise.all`
+over folders into a shared `cubes` object, so which source was "first" and which
+was "the duplicate" varied run to run.
+
+Both are one restructure. Scanning and id resolution are now separate passes:
+each root fills its own `ScanResult`, the lists are concatenated in root order
+(`Promise.all` preserves input order regardless of completion order), and a
+grouping pass builds `cubes` and the errors. `scanDirectory` no longer decides
+anything about ids, so it always descends. Directory entries are sorted, and a
+directory reachable from two roots is deduped by path — one cube seen twice is
+not a collision, which it used to be reported as.
+
+**0.3 `apt:essentials` is already declared twice.** `cubes/apt/essentials`
+declares it via `id`; `packages/nopy/cubes/apt/essentials` declared it via an
+`[apt:essentials]` prefix in `name`. `cubeDirs` merges root-first, so running
+`nopy` from `packages/nopy` collected both and aborted. Confirmed against the
+real trees before the rename:
+
+```
+Duplicate cube id 'apt:essentials' from 2 sources:
+  /…/ansiblingz/cubes/apt/essentials
+  /…/ansiblingz/packages/nopy/cubes/apt/essentials
+Rename one of them, or remove a source from .nopyrc.json.
+```
+
+The three `packages/nopy/cubes` fixtures are now `[test:apt-essentials]`,
+`[test:apt-all]` and `[test:apt-more]`; all 25 cubes load with no errors. Their
+`dependencies` were stale too — they named `apt/more` and `apt/essentials`,
+which are not ids anything declares — so they now point at the renamed ids.
+
+**0.4 `coerceValue` breaks if zod is ever duplicated.** `nopy.prompts.ts:147-154`
+discriminated with `instanceof z.ZodDefault`, `z.ZodBoolean`, `z.ZodNumber` and
+friends — checks against the *running CLI's* zod instance. The moment a bundle
+resolves its own copy of zod (entirely possible once manifests arrive from
+`node_modules`; see Phase 4), every check returns false and `coerceValue` falls
+through to the raw string, silently. Booleans stop being booleans.
+
+`defaultValueOf` in `cubes/types.ts` had the same breakage, reached whenever a
+schema has one field without a `.default()` — `getDefaults()` tries
+`safeParse({})` first, which is instance-agnostic, and only then drops to the
+per-field read.
+
+Both now discriminate on `def.type`, a plain string that holds across instances,
+via two exported helpers (`zodKind`, `zodInner`). Verified on the installed zod
+4.4.3:
+
+```
+z.boolean().default(false).def.type        → 'default'
+z.boolean().default(false).def.innerType   → { def: { type: 'boolean' } }
+z.number().def.type                        → 'number'
+```
+
+`tests/helpers/foreign-zod.ts` rebuilds a schema as plain objects carrying zod's
+`def` but not its prototype — structurally what a second copy of zod produces,
+and `instanceof`-blind, so neither call site can regress.
+
+Worth noting for Phase 4: zod 4 exposes `def.defaultValue` as a getter that
+already invokes a lazily declared default, so the `typeof === 'function'` branch
+in `defaultValueOf` is now dead. It is kept as insurance against that changing.
+
+## Phase 1 — the bundle contract
+
+A cube bundle is an npm package with a `nopy` field:
+
+```json
+{
+  "name": "@acme/cubes-net",
+  "version": "1.0.0",
+  "type": "module",
+  "nopy": { "cubes": ["./cubes"] },
+  "files": ["cubes", "README.md", "LICENSE"],
+  "keywords": ["nopy", "nopy-cubes", "pyinfra"],
+  "dependencies": {
+    "@bitsquare/nopy-cube": "^1.0.0",
+    "zod": "^4.4.3"
+  },
+  "publishConfig": { "access": "public" }
+}
+```
+
+Rules:
+
+- `nopy.cubes` — directories relative to the package root, scanned exactly like
+  `cubeDirs` entries. Required; a package listed in `cubePackages` without a
+  `nopy` field is an error, not a silent skip. Listing it means the user expects
+  cubes from it.
+- Both dependencies are **regular dependencies, not peers**, and both are
+  load-bearing: a manifest imports `Manifest` from `@bitsquare/nopy-cube` and `z`
+  from `zod`. `@bitsquare/nopy-cube` peer-depends on zod, so the bundle's copy is
+  the one everybody uses — see Phase 4.
+- The package needs no `exports` entry for this to work — resolution reads
+  `package.json` off disk (Phase 2), so the `exports` map is irrelevant.
+- **A bundle's directory is read-only at runtime.** Under pnpm, `node_modules`
+  content is hardlinked into the global store; a cube writing next to its own
+  `deploy.py` corrupts that store for every project on the machine. Cubes must
+  write to `/tmp` or the remote host, never their own dir.
+- A bundle must not ship a `.nopyrc.json`. Config discovery walks up from
+  `process.cwd()`, never from cube directories, so it would never be read.
+
+## Phase 2 — resolution
+
+### Config surface
+
+```json
+{
+  "cubePackages": ["@acme/cubes-net", "@acme/cubes-caddy"]
+}
+```
+
+Merges through the existing `resolution` machinery for free — arrays concat and
+dedupe — so a parent config supplies the org baseline and a child adds to it.
+
+**Resolution origin.** A package must be resolved from *the directory of the
+config file that declared it*, not from `process.cwd()`. Otherwise a bundle
+listed in `~/.nopyrc.json` cannot resolve unless every project happens to depend
+on it. This is the same problem `PATH_PROPERTIES` solves for `cubeDirs`, but the
+output is a tagged reference rather than a rewritten string:
+
+```ts
+export interface CubePackageRef {
+  spec: string;   // '@acme/cubes-net'
+  from: string;   // dirname of the .nopyrc.json that declared it
+}
+```
+
+So the file format and the loaded format diverge for this one key:
+
+```ts
+interface NopyConfigFile extends Omit<Partial<NopyConfig>, 'cubePackages'> {
+  cubePackages?: string[];
+  resolution?: ResolutionConfig;
+}
+
+interface NopyConfig {
+  cubePackages: CubePackageRef[];
+  // ...
+}
+```
+
+`resolveConfigPaths()` performs the `string → CubePackageRef` conversion, next to
+where it resolves `PATH_PROPERTIES`. Two consequences to handle:
+
+- `mergeValue`'s array dedupe only fires when every element is a primitive
+  (`config.ts:142`), so refs fall through to plain concat. Dedupe by `spec` in
+  the resolver instead.
+- Dedupe is **last-wins**: merge order is root-first, so the last occurrence is
+  the most specific config, and its `from` is the right resolution origin.
+
+### Resolver
+
+New file `packages/nopy/src/cubes/packages.ts`:
+
+```ts
+export interface CubePackage {
+  name: string;
+  root: string;
+  dirs: string[];   // absolute, from nopy.cubes
+}
+
+export function resolveCubePackages(
+  refs: CubePackageRef[]
+): { packages: CubePackage[]; errors: string[] };
+```
+
+Locate the package root without going through `exports` and without tripping on
+pnpm symlinks:
+
+```ts
+const req = createRequire(path.join(ref.from, 'noop.js'));
+for (const dir of req.resolve.paths(ref.spec) ?? []) {
+  const manifest = path.join(dir, ref.spec, 'package.json');
+  if (fs.existsSync(manifest)) return path.dirname(manifest);
+}
+```
+
+`resolve.paths()` walks the `node_modules` chain upward from `ref.from` plus the
+global paths; `existsSync` follows symlinks, so pnpm's
+`node_modules/@acme/cubes-net → ../.pnpm/…` resolves correctly.
+
+Errors (each aborts the run, consistent with the existing `errors` contract):
+
+- package not found on any candidate path
+- `package.json` unparseable
+- no `nopy.cubes`, or it is not a non-empty array of strings
+- a `nopy.cubes` entry escapes the package root, or does not exist
+
+### Wiring
+
+`findCubeDirectories()` currently returns `string[]`. It becomes the union of
+three sources, each tagged so the loader can attribute a cube to it:
+
+```ts
+export type CubeRoot =
+  | { type: 'dir'; dir: string }                              // cubeDirs, .npcubes markers
+  | { type: 'package'; dir: string; packageName: string };    // cubePackages
+
+export function findCubeRoots(): { roots: CubeRoot[]; errors: string[] };
+```
+
+Keep `findCubeDirectories()` as a thin wrapper returning `roots.map(r => r.dir)` —
+it is exported from `src/cubes/index.ts` and covered by tests. The
+`node_modules` skip inside `scanDirectory` stays and is now *correct*: a
+bundle's own `node_modules` should not be scanned.
+
+## Phase 3 — hard errors with attribution
+
+`Cube` gains a source, as an optional fourth constructor parameter so the public
+signature stays backwards compatible:
+
+```ts
+export type CubeSource =
+  | { type: 'dir'; dir: string }
+  | { type: 'package'; packageName: string; dir: string };
+
+class Cube {
+  constructor(
+    manifest: Manifest<Schema>,
+    dir: string,
+    deployScript: string,
+    source: CubeSource = { type: 'dir', dir }
+  ) {}
+}
+```
+
+The duplicate error carries both sources and is order-independent (Phase 0.2):
+
+```
+Duplicate cube id 'apt:essentials' from 2 sources:
+  package @bitsquare/cubes-core  /…/node_modules/@bitsquare/cubes-core/cubes/apt/essentials
+  directory                      /repo/packages/nopy/cubes/apt/essentials
+Rename one of them, or remove a source from .nopyrc.json.
+```
+
+There is deliberately no override, alias or precedence rule. If two bundles ever
+claim the same id they are mutually exclusive, and the fix is upstream.
+
+Surface the source in the interactive picker and in `--json` output so a user can
+see where a cube came from before running it.
+
+## Phase 4 — `@bitsquare/nopy-cube`, the authoring package
+
+The problem: a manifest does `import { cubes } from '@bitsquare/nopy'`, resolved
+by ordinary Node resolution from the manifest's own directory. From inside
+`node_modules/@acme/cubes-net/`, that only resolves if the consumer installed
+`@bitsquare/nopy` locally — a globally-installed CLI leaves nothing to find.
+
+The fix is to give bundles something they can depend on *normally*, so resolution
+is plain, boring, spec-compliant Node with no loader tricks in the critical path.
+
+### The package
+
+`packages/nopy-cube` — the `Manifest` factory, the `Cube` class, and the types
+from `cubes/types.ts`. No CLI, no `execa`, `inquirer`, `enquirer`, `zx`, or
+`commander`. Today a cube manifest — a file that ships nothing but data — drags
+the entire CLI in as a transitive dependency; this makes the authoring surface
+honest about how small it is, and gives the *contract* a version number that
+moves independently of the CLI's.
+
+```json
+{
+  "name": "@bitsquare/nopy-cube",
+  "version": "1.0.0-alpha0",
+  "type": "module",
+  "exports": { ".": { "types": "./dist/index.d.ts", "default": "./dist/index.js" } },
+  "peerDependencies": { "zod": "^4.4.3" },
+  "files": ["dist", "README.md", "LICENSE"]
+}
+```
+
+**zod is a peer, deliberately.** Bundles declare zod as a regular dependency, so
+exactly one zod instance serves the manifest, the schema it builds, and the
+`Manifest` factory. Phase 0.4 removes the CLI's `instanceof` dependence on that
+being the *same* copy the CLI uses, but keeping the bundle side single-instance
+is still the right default.
+
+### Moving `cubes/types.ts`
+
+`@bitsquare/nopy` re-exports everything from `@bitsquare/nopy-cube` — through
+`src/cubes/index.ts` and the `cubes` namespace in `src/nopy.cubes.ts`, both
+already coverage-excluded barrels — so `import { cubes } from '@bitsquare/nopy'`
+in every existing manifest keeps working unchanged. Nothing in `cubes/` has to be
+touched at migration time.
+
+Repo plumbing this requires:
+
+- `tsconfig.base.json`: add `"@bitsquare/nopy-cube": ["./packages/nopy-cube/src"]`
+  to `paths`.
+- Root `tsconfig.json`: add the project reference.
+- `packages/nopy/tsconfig.json`: `references` is currently `[]` — add
+  `{ "path": "../nopy-cube" }`. This is the first reference edge in the repo, so
+  `tsc --build` ordering starts mattering.
+- `packages/nopy/package.json`: `"@bitsquare/nopy-cube": "workspace:*"`.
+- A `vitest.config.ts` for the new package with the same thresholds. `Manifest()`,
+  `Manifest.create()` and `Cube.getDefaults()` all carry logic, so the relevant
+  cases move over from `tests/cubes.factories.test.ts`.
+
+### The release lane needs fixing first
+
+This is the part that is easy to miss. `link-workspace-packages` is unset and
+pnpm 10+ defaults it to `false`, so a plain semver range would resolve
+`@bitsquare/nopy-cube` from the registry instead of linking the workspace copy —
+the dependency has to use `workspace:*`.
+
+But **both workflows publish with `npm publish`**, and npm does not understand
+the `workspace:` protocol. `@bitsquare/nopy` would ship a manifest carrying
+`"@bitsquare/nopy-cube": "workspace:*"`, which fails on install with
+`EUNSUPPORTEDPROTOCOL`. This has never mattered because the two current packages
+do not depend on each other; `nopy → nopy-cube` is the first edge, and the PoC
+bundle in Phase 5 adds a second.
+
+Pick one before publishing anything:
+
+- **Switch to `pnpm publish --no-git-checks`**, which rewrites the protocol to a
+  concrete version on pack. Cleanest, but changes the publish step in both
+  workflows and pulls in pnpm's own lifecycle behaviour.
+- **Rewrite the range with `npm pkg set` before publishing**, extending the
+  pattern `publish-snapshot.yml` already uses for `version`. In `release.yml` one
+  package ships at a time, so it pins to whatever version `packages/nopy-cube/package.json`
+  declares at that commit. In `publish-snapshot.yml` the loop needs to become two
+  passes — compute every snapshot version first, then publish — so `nopy` can pin
+  the exact `nopy-cube` snapshot from the same run.
+
+Recommendation: `pnpm publish`, and verify against the Gitea registry with a
+throwaway version before the first real release.
+
+### Also: the resolve hook
+
+Independent of the split, and worth building anyway — it retires the
+`ERR_MODULE_NOT_FOUND` gotcha CLAUDE.md documents for the local `cubes/` tree,
+where manifests import `@bitsquare/nopy` from a directory that has no link to it.
+
+With the split, the hook is a convenience rather than load-bearing: bundles
+resolve `@bitsquare/nopy-cube` through their own `node_modules` and never reach
+it.
+
+**The gotcha is bigger than CLAUDE.md says: it is two specifiers, not one.**
+Measured by linking `@bitsquare/nopy` into the root `node_modules` and loading
+the real tree — every manifest then failed on `Cannot find package 'zod'`
+instead. Manifests import `z` directly to build their schema, and pnpm's
+isolated layout puts zod under `packages/nopy/node_modules`, not the root. A
+hook that only covers `@bitsquare/nopy` moves the error rather than fixing it,
+so it has to fall back for `zod` too. With both linked, all 25 cubes load.
+
+Falling back for `zod` hands local cubes the *CLI's* zod instance, so no
+duplication arises there. Bundles are the case that duplicates it, and Phase 0.4
+is what makes that safe.
+
+New `packages/nopy/src/nopy.resolve-hook.mjs`, registered once from `loadCubes()`
+before the first `import(manifestPath)`:
+
+```ts
+module.register('./nopy.resolve-hook.mjs', import.meta.url, {
+  data: { fallback: import.meta.resolve('./index.js') },
+});
+```
+
+The hook tries `next(specifier, ctx)` **first** and only falls back to the
+running CLI's own copy on failure. That ordering matters: a consumer that has its
+own `@bitsquare/nopy` installed keeps using it, so the hook never silently
+introduces version skew.
+
+Constraints:
+
+- `module.register()` is process-global and cannot be undone. Install it once,
+  behind a module-level guard.
+- The hook file runs on a separate thread; the `data` payload must be
+  structured-cloneable (a string URL is).
+- The `.mjs` must ship in `dist` and be listed in `files` — it already is, via
+  the `dist` entry.
+- It resolves `@bitsquare/nopy` and `zod`, not `@bitsquare/nopy-cube`. Bundles
+  never depend on the hook; only the in-repo `cubes/` tree and hand-written local
+  cubes do.
+
+## Phase 5 — proof of concept: `packages/cubes-core`
+
+Depends on Phase 4 shipping first — the bundle cannot declare
+`@bitsquare/nopy-cube` as a dependency until it exists, and the publish-lane fix
+has to be in place before either package is published.
+
+1. `git mv cubes packages/cubes-core/cubes` — preserves per-file history.
+2. Add `packages/cubes-core/package.json` per the Phase 1 contract. Version
+   `1.0.0-alpha0`, tracking the current alpha train. Not private. Its
+   `@bitsquare/nopy-cube` dependency uses `workspace:*` in the repo, which is
+   exactly the case the Phase 4 publish fix has to handle.
+   Migrating the manifests' `import { cubes } from '@bitsquare/nopy'` to
+   `import { Manifest } from '@bitsquare/nopy-cube'` is optional — the re-export
+   keeps the old form working — but doing it here is what proves the bundle
+   resolves without the CLI present at all.
+3. Root `.nopyrc.json`: **replace** `"cubeDirs": ["./cubes"]` with
+   `"cubePackages": ["@bitsquare/cubes-core"]`. Replace, not add — keeping both
+   means every id resolves from two sources and the hard error fires on every
+   run.
+4. Root `package.json`: add `"@bitsquare/cubes-core": "workspace:*"` to
+   `devDependencies`, so pnpm symlinks it into the root `node_modules`. This is
+   what makes the PoC exercise the real pnpm symlink resolution path rather than
+   a plain directory.
+5. `packages/nopy/.nopyrc.json` keeps `"cubeDirs": ["./cubes"]` for its fixtures.
+   Config merges root-first, so running from `packages/nopy` now pulls in
+   `@bitsquare/cubes-core` *and* the fixtures — which is exactly the collision
+   Phase 0.3 renames away.
+6. Workflow changes are limited to the publish-lane fix from Phase 4.
+   `publish-snapshot.yml` loops `for dir in packages/*/` and picks both new
+   packages up automatically; `release.yml` resolves `packages/<pkg>` from the
+   tag, so `cubes-core-v1.0.0` and `nopy-cube-v1.0.0` work as-is. Verify on the
+   first snapshot run that a package with no `build` script is skipped cleanly by
+   `pnpm -r run build` (it is) and that publishing is happy with no lifecycle
+   scripts.
+7. No `tsconfig` reference for `cubes-core` — the bundle has no TypeScript. (The
+   `nopy-cube` references from Phase 4 are separate.)
+8. Biome already lints `cubes/**/*.mjs` from the root; only the path changes.
+
+### Verifying the PoC
+
+- **In-workspace:** `pnpm --filter @bitsquare/nopy run nopy -P` from the repo
+  root lists `net:tailscale`, `apt:install`, … and prints deploy commands whose
+  `--chdir` points into `node_modules/@bitsquare/cubes-core/cubes/…`.
+- **Out-of-workspace (the real test):** `npm pack` the bundle, install the
+  tarball into a throwaway directory with a `.nopyrc.json` naming it, install
+  `nopy` *globally*, and run `nopy -P`. This is what actually exercises Phase 4 —
+  a manifest resolving its import from a `node_modules` tree that has no
+  `@bitsquare/nopy` in it. Check the installed tarball's `package.json` really
+  carries a concrete `@bitsquare/nopy-cube` range and not `workspace:*`.
+
+## Phase 6 — documentation
+
+- `CLAUDE.md`: the repo table gains two rows (`packages/nopy-cube`,
+  `packages/cubes-core`) and loses the `cubes/` one; "The two packages do not
+  depend on each other" is no longer true; the loader section in *nopy
+  architecture*; and the *Gotcha* paragraph, which the resolve hook retires.
+- `packages/nopy/docs/CUBE-BUNDLES.md` (new): authoring guide — package shape,
+  read-only constraint, id collision policy, publishing.
+- `packages/nopy/docs/API.md` + `README.md`: `cubePackages`.
+- `README.PUBLISH.md`: `nopy-cube-v*` and `cubes-core-v*` as new tag prefixes,
+  plus the ordering constraint — `nopy-cube` releases before anything that
+  depends on it.
+
+## Testing
+
+The coverage gate (85 % branches/functions, 80 % lines/statements, per package)
+is not a CI flag — new modules without tests fail the gate locally and on the
+runner alike.
+
+`tests/cubes.packages.test.ts` (new) — build a fake `node_modules` tree under
+`os.tmpdir()` and `chdir` into it, as the existing loader/config tests do:
+
+- resolves a scoped and an unscoped package
+- resolves through a symlinked package directory (mimicking pnpm)
+- resolves from the declaring config's directory, not `cwd`
+- missing package → error naming the spec
+- package without `nopy.cubes` → error
+- `nopy.cubes` entry that does not exist, and one that escapes the root → errors
+- last-wins dedupe when parent and child config both name a package
+
+`tests/cubes.loader.test.ts` — package-sourced cubes load; `source` attribution
+is correct for all three root types.
+
+`tests/cubes.loader.edge.test.ts` — duplicate across a dir and a package errors
+and names both; cubes nested below a duplicate still get scanned (Phase 0.1);
+the error is identical regardless of scan order (Phase 0.2).
+
+`tests/config.test.ts` — `cubePackages` merge, `override` resolution strategy,
+`CubePackageRef` provenance.
+
+`tests/prompts.test.ts` — `coerceValue` against schemas built by a *different*
+zod instance, so Phase 0.4 cannot silently regress to `instanceof`.
+
+`packages/nopy-cube/` — its own `vitest.config.ts` at the same thresholds. The
+`Manifest()` / `Manifest.create()` / `Cube.getDefaults()` cases move over from
+`tests/cubes.factories.test.ts`; what stays behind is whatever tests the
+re-export surface.
+
+Resolve hook — `module.register()` is process-global, so this cannot be unit
+tested in-process. Add an integration test that spawns the CLI as a child process
+against a fixture tree, under the existing `test:integration` script.
+
+## Risks
+
+1. **`module.register()` is irreversible and process-wide.** It affects
+   everything loaded afterwards, including the CLI's own lazy imports. Guarded
+   single install, `next()`-first ordering.
+2. **Hard-error duplicates have no escape hatch.** Two bundles claiming one id
+   cannot be used together, full stop. If that bites in practice the follow-up is
+   a `cubeAliases` map or a per-package id prefix — explicitly out of scope here.
+3. **Store corruption.** A bundled cube writing to its own directory damages the
+   pnpm global store for every project on the machine. Documented in Phase 1;
+   a runtime warning is a possible follow-up.
+4. **No version compatibility check.** A bundle authored against a future `nopy`
+   loaded by an older one fails at manifest-import time with a confusing error.
+   A `nopy.engines` field checked at resolution time would fix it. Deferred.
+5. **Bundles vendoring cubes in their own `node_modules`** will not be found, by
+   design.
+6. **`workspace:*` escaping into a published manifest.** The failure is silent at
+   publish time and only shows up when someone installs the package. Phase 4
+   fixes the lane; a `postpack` assertion that no dependency range starts with
+   `workspace:` would make it impossible to regress.
+7. **Three packages, three version lines.** `nopy-cube` is the contract, so a
+   breaking change there ripples to every published bundle in the wild — which is
+   the point of versioning it separately, but it means the compatibility question
+   from risk 4 gets more pressing, not less.

 ## Mechanics

-### Sequential Execution
+### Execution Order

-In sequential execution mode (the default), cubes added via hooks will follow the order in which they were pushed to the deployment plan:
+Cubes are always deployed sequentially, in the order they were pushed to the deployment plan. For a cube with hooks that means:

 1. Cubes from `before` hooks.
 2. The current cube itself.
 3. Cubes from `after` hooks.

-### Parallel Execution
-
-In parallel execution mode, cubes added via hooks **do not automatically inherit dependencies**.
-
-If a `before` hook calls `exec('setup-cube')`, it ensures that `setup-cube` is placed earlier in the deployment plan, but for parallel execution, you should still ensure that dependencies are correctly specified if one cube relies on another's completion.
+Because a `before` hook only places its cube *earlier in the plan*, it guarantees ordering but not much else — if the relationship is a real dependency rather than a one-off ordering nudge, declare it in `dependencies` so it is resolved and deduplicated like any other.

+    - Replayed session values moved from the `defaults` scope to `prompts`, so they keep outranking `env` now that `env` sits higher.
+    - `Cube.getDefaults()` no longer discards every default when one field lacks `.default()`; it falls back to a per-field read.
