 ## [Unreleased]
 
+## [1.3.6] - 2026-07-23
+
+### Bumped
+- sso-manager-node -> [v1.3.2](https://github.com/theta42/sso-manager-node/releases/tag/v1.3.2)
+
+sso-manager-node 1.3.2:
+
+### Fixed
+- **OAuth client management API returned `client_id: undefined` on every GET**, which broke this stack's bootstrap: it lists the OAuth clients and rotates by the returned `client_id`, so it called `/api/oauth/client/undefined/rotate` and got a 500 — aborting `setup.sh` with `bootstrap failed` whenever `proxy-secrets.js` had no usable secret (e.g. a fresh/rotated deployment). The ORM's `toJSON()` was stripping the mapped `client_id`/`scopes`/… fields; `OAuthClient.get()` now emits them explicitly (and omits `client_secret_hash`). Unknown client ids now 404 instead of 500.
+
+## [1.3.5] - 2026-07-23
+
+### Added
+- **Optional SSH jump host** (theta42/jump-host) as a third, opt-in submodule. Enable with `CFG_JUMP_HOST_ENABLED=true` in `setup.env`: setup.sh clones/tag-tracks the submodule and builds it behind the `jump-host` compose profile, the bootstrap mints a directory API token and writes `./config/jump-secrets.js` (LDAP admin bind so it can inject users' `sshPublicKey`), the jump host is registered as a proxy Host (its web UI) and seeded as a directory service. Users then `ssh uid_-_host@jump.<domain>` (WinSCP-friendly) or `ssh uid@jump.<domain>` for a TUI host picker; the web UI on :3002 shows audit + metrics. Off by default — existing installs are unaffected.
+
+## [1.3.4] - 2026-07-23
+
+### Bumped
+- sso-manager-node -> [v1.3.1](https://github.com/theta42/sso-manager-node/releases/tag/v1.3.1)
+
+sso-manager-node 1.3.1:
+
+### Added
+- The Directory documentation (`docs/directory.md`) is now surfaced: registered in-app at `/docs/directory` ("Directory & Inventory"), help-linked from the Directory page header, and linked from the docs-site index. Extended with the shared slug conventions (`site_<name>`, `host_<hostname>` — as used by ldap-client and the theta-env seed), the automatic-registration story (theta-env stack seeding, ldap-client Linux host enrollment), and the API surface (admin at `/api/directory-admin`, read-only graph at `/api/discovery`).
+
+### Changed
+- Direct LDAP binds are described as first-class, not "legacy", across README, DEPLOYMENT.md, docs, and the Dockerfile: Linux hosts are a primary consumer of the directory (PAM/SSSD login, LDAP-backed `sudo` via `sudoRole`, SSH public keys via openssh-lpk) — exactly what the custom schemas exist for.
+
+### theta-env own changes
+
+### Added
+- `CFG_SITE_NAME` in `setup.env` (right below `CFG_DOMAIN`, default `local`): names the SSO directory site the stack registers itself under — slug `site_<name>`, matching the `parentSlug` convention ldap-client-joined Linux hosts use, so they land under the same site.
+- The directory seed now collects real host facts on the machine (hostname, IP, MAC of the default-route interface, OS pretty-name, kernel — same collection as `ldap-client/index.sh`) and registers the stack host as `host_<hostname>` with that metadata, plus fills in each service's internal port and git repo (`sso-manager` 3001, `proxy` 3000, `openldap` 389/636, `openresty` 443). Existing resources from the earlier seed layout (`stack-host`, domain-slug site) are adopted in place — seed metadata only fills fields the operator hasn't set, never overwrites.
+- The bootstrap now seeds the SSO directory with the stack's own resources: a site (from the configured domain), a "Stack host", and the SSO Manager + Proxy services (with their public URLs in metadata), linking the proxy's auto-registered OAuth client under its service. Also seeds the two non-obvious services the stack runs: the OpenLDAP directory (advertising the `ldaps://` endpoint Linux hosts and LDAP-native apps bind to, honoring `ldap.ldapsHost`) and the OpenResty edge (the 80/443 data plane every hostname flows through, with a wildcard `https://*.<domain>` address). The Directory page is populated out of the box instead of starting empty. Idempotent — resources whose slug already exists are operator-owned and never touched, and a seed failure only warns (never fails a bring-up, e.g. against an older sso-manager image without `/api/directory`).
