 `install.sh` performs the manual steps below, is idempotent, and never overwrites an existing file (it skips and tells you). It detects your package manager (npm, pnpm — workspaces included, yarn, bun) for the `yaml` dependency, and a dependency failure warns instead of aborting the install. Run it from the root of your repository; pass your first domain name as the argument. It refuses to run in a subdirectory of a repository that already runs Knowledge-Driven Engineering — a second catalog nothing reads — and names the directory to run it from. The argument only seeds a fresh install: on a repository that already has `knowledge/index.yaml` the installer creates no domain and points you to `npm run knowledge -- domain add <name>`. Installing, upgrading (`--upgrade`) and adding a domain are three separate actions. Offline installs work from a local clone: `KDE_SOURCE=/path/to/clone bash install.sh <domain>`. The script installs the release it belongs to (the tag in its own URL); to install another release, a branch or a commit, set `KDE_VERSION=main` (or `KDE_VERSION=v0.7.2`) in front of the command.
 
+Canonical knowledge lives under `knowledge/` by default. To keep it elsewhere — `docs/knowledge`, `spec`, any directory your repository already reads — set `KDE_KNOWLEDGE_DIR=docs/knowledge` in front of a fresh install. The installer scaffolds the tree there, writes the agent rules with that path, and records it as `"kde": { "knowledge": "docs/knowledge" }` in `package.json`; every tool and later installer run reads the location back from that key, so nothing else needs the path. Domain paths inside the catalog are explicit already. The directory must be a relative path inside the repository; dot-directories such as `.agents/` or `.claude/` are refused, because the validator never scans them and knowledge reviewed in pull requests should not hide in a tool's folder. To relocate an installed tree, move it and change the `package.json` key by hand.
+
 ## Upgrading
 
 The installer classifies what it writes by owner (DR-011):
 
 - **Framework-owned** — `tools/knowledge-check.mts`, `tools/knowledge-context.mts`, `tools/knowledge.mts`, `tools/drift-gate.mts`, `tools/knowledge-hook.mts`, `.github/workflows/kde.yml`, the `<!-- kde:begin -->` … `<!-- kde:end -->` section of `AGENTS.md` (DR-017), and the Knowledge-Driven Engineering hook entries in `.claude/settings.json`. Every copy carries a `kde-version: X.Y.Z` marker on its first line.
-- **Adopter-owned** — everything under `knowledge/`, `templates/`, `AGENTS.md` outside the kde markers, and your `package.json` beyond the `knowledge`, `knowledge:check` and `knowledge:context` scripts. Never touched, on any run. Templates are yours to shape to your team's conventions; the validator, not the template text, enforces KDE-SPEC-001.
+- **Adopter-owned** — everything under `knowledge/` (or the directory `kde.knowledge` names), `templates/`, `AGENTS.md` outside the kde markers, and your `package.json` beyond the `kde` key and the `knowledge`, `knowledge:check` and `knowledge:context` scripts. Never touched, on any run. Templates are yours to shape to your team's conventions; the validator, not the template text, enforces KDE-SPEC-001.
 
 Every run compares the installed markers with the fetched version and warns when a framework-owned file differs — whether from a newer release upstream or a local edit. To refresh them:
 
 ```bash
-curl -fsSL https://raw.githubusercontent.com/emafriedrich/knowledge-driven-engineering/v0.8.1/install.sh | bash -s -- --upgrade
+curl -fsSL https://raw.githubusercontent.com/emafriedrich/knowledge-driven-engineering/v0.9.0/install.sh | bash -s -- --upgrade
 ```
 
 `--upgrade` replaces framework-owned files that differ and reports each one (`upgrade tools/knowledge-check.mts (0.1.0 -> 0.2.0)`). A framework-owned file you edited locally is overwritten too, with an explicit `WARN` line naming it. Framework-owned files are not an extension point: if you need different validation behaviour, fork this repository and install from your fork; if the change would help everyone, contributions are welcome. Adopter-owned files are not touched by `--upgrade`. Templates are never overwritten; the installer prints a `note` line for each one that differs from the release, with the upstream URL, so you can decide whether to adopt the newer shape. Without branch protection and CODEOWNERS, human-only promotion is a procedural guarantee: the validator sees that an approver is recorded, not who typed it. New template files that a release adds (as `templates/model.md` and `templates/contract.md` were) arrive on a plain run, because the installer adds any file that does not exist yet.

+# DR-021: The knowledge directory is configurable through package.json kde.knowledge; dot-directories are refused
+
+## Context
+
+DR-005 fixed `knowledge/` as the entry point for canonical knowledge, and every tool, the installer and the agent rules spelled that path out. Teams that adopt the method on an existing repository often already have a place readers look for this kind of document — `docs/`, a `spec/` tree, a monorepo convention — and a second top-level folder competes with it instead of joining it.
+
+The catalog already declares each domain's `path`, so domain trees are relocatable today. The only path the tools assumed was the location of the root catalog itself.
+
+## Decision
+
+The directory that holds the root catalog is configurable per repository with one key in `package.json`:
+
+```json
+"kde": { "knowledge": "docs/knowledge" }
+```
+
+The default stays `knowledge`. `tools/knowledge-check.mts` exposes `knowledgeDir()`, and the validator, the lifecycle commands, the drift gate, the manifests and the harness hook derive the catalog location from it. The installer accepts `KDE_KNOWLEDGE_DIR` on a fresh install, scaffolds the tree there, writes the agent rules with that path and persists the key; later runs read the key back and never move an installed tree.
+
+The value must be a relative directory inside the repository with no dot-segments. Dot-directories such as `.agents/` or `.claude/` are refused: the validator skips them when it walks the repository, they belong to one tool rather than to the team, and knowledge reviewed in pull requests should stay visible in the tree and on the forge.
+
+## Consequences
+
+Adopters choose where canonical knowledge lives without forking the tools, and the framework keeps a single word for it. No new configuration file: the key sits next to the scripts the installer already writes.
+
+Documentation and examples in this repository keep using `knowledge/`, the default, so prose does not have to hedge on every mention. A repository that renames its directory reads the adopter guide once.
+
+Relocating an installed tree is a manual move plus a key change; the installer refuses a conflicting `KDE_KNOWLEDGE_DIR` on a repository that already has a catalog, so an accidental variable cannot split knowledge across two directories.
+
+## Supersession
+
+None. DR-005 still holds: the directory is organised by domain first, wherever it lives.
