 # Changelog
 
+## 0.1.10 — sites `fmt|pdx|roam`, and a read grant that outlives the tunneller (2026-09-13)
+
+- **Install kits for every backend registered since 2026-09-08 died at `--site`** (deployd#3,
+  DD-0620): tenancy 0.7.x issues `fmt | pdx | roam`, deployd still enforced `cbs | pdx`. `SITES`,
+  `install.sh` and `config.example.yaml` now accept `fmt | cbs | pdx | roam` (`cbs` = the deprecated
+  alias of `fmt` on rows registered before the rename) and a test pins the set to tenancy's.
+- **The agent's read on the ziti identity now survives a tunneller rewrite for real.** 0.1.8 made
+  `monky-deployd` a member of the `ziti` group; that is not enough: `ziti-edge-tunnel` re-creates the
+  file with mode `0600`, which sets the ACL mask to `---` and defeats the group read and the named-user
+  entry alike (env-dev-08, 2026-09-11 → 09-13: two days of *"identity is not readable"* ticks under a
+  healthy tunnel; the backend went `offline`). New `identity-acl.sh` re-applies the entries **and the
+  mask**; `monky-deployd-identity-acl.path` re-runs it whenever the identity directory changes;
+  `install.sh` and the package postinstall arm it.
+
+## 0.1.9 — an upgrade no longer stops the agent (2026-09-09)
+
+- **`dpkg -i` over a running agent disabled it.** dpkg calls the OLD package's `prerm` on an
+  **upgrade** as well as on a removal (rpm passes a remaining-instance count), and `preremove.sh`
+  ran `systemctl disable --now monky-deployd.timer` unconditionally. Upgrading env-dev-01 and
+  env-dev-08 from 0.1.6/0.1.7 to 0.1.8 stopped and **disabled** both agents. It is silent: the box
+  stays up, the containers keep running, and nothing reports that check-ins have ceased — the
+  backend simply stops converging. `preremove.sh` now returns early for every upgrade shape
+  (`upgrade`, `failed-upgrade`, `deconfigure`, rpm's `1`), and `postinstall.sh` `try-restart`s the
+  long-lived proxy unit so it picks up the new code. A fleet upgrade would have taken every agent
+  offline at once.
+
+## 0.1.8 — onboarding: keep the identity readable, refuse a full disk (2026-09-09)
+
+Three faults from one onboarding (env-dev-08, agent-managed, 2026-09-09), each of which sent the
+diagnosis somewhere other than the fault.
+
+- **The agent's read on the ziti identity now survives a tunneller rewrite.** `install.sh` granted it
+  with a POSIX ACL. `ziti-edge-tunnel` rewrites the identity file whenever the controller sends a config
+  update, and the rewrite drops the ACL — the agent had applied cleanly and was failing every tick six
+  minutes later. The durable grant is **group membership**: `install.sh` and the package's postinstall
+  now add `monky-deployd` to the identity file's group (`ziti`) when it exists, and a **default ACL** on
+  the identity directory carries the grant onto a freshly created file. The explicit ACLs stay.
+- **An unusable identity says so.** `openziti.load()` accepts an unreadable or malformed identity, logs
+  "configuration is invalid" at the C layer and hands back a context that fails LATER, at dial, as a
+  bare `TypeError` — which the transport reported as a missing intercept or a policy gap. The SDK
+  transport now reads and parses the identity itself first, and names the real fault (absent, not
+  readable by this uid, or not JSON) before anything touches the mesh.
+- **A full disk is refused before the pull, and the right disk is measured.** The pre-flight ran only
+  when the bundle declared `disk_need_bytes`; a bundle without one sailed past it and died mid-pull with
+  containerd's `no space left on device`, which reads as a registry fault. A bundle that declares no size
+  now has to clear the headroom floor. The pre-flight also measures **containerd's root as well as the
+  docker data-root**: docker 29 keeps image layers in the containerd image store, and on env-dev-08 those
+  were on different filesystems — 93 GiB free where the agent looked, 2.8 GiB where the pull wrote.
+
+## 0.1.7 — registry credential + a pull error you can read (2026-09-08)
+
+- **No hand `docker login` on a new box** (monky-design-docs !225, doc 24 §4a). A manifest entry marked
+  `use: registry-auth` is the Harbor pull credential, not an env var: it is written to
+  `<state_dir>/docker/config.json` (0600, in a directory the agent owns) and the docker CLI is pointed at it
+  with an explicit **`DOCKER_CONFIG`**. That last part is the trap — the unit runs as `monky-deployd`, so a
+  `docker login` by a human or by root is invisible to the agent and looks exactly like no credential at all
+  (env-dev-01, 2026-09-08). Both seeded shapes are accepted: a JSON object, or `username:password` with the
+  registry from the new `registry_host` config.
+- **`compose pull` failures carry the registry's own message** instead of `rc=1`. "no basic auth
+  credentials", "manifest unknown" and DNS failures now reach the journal and the report to tenancy.
+
+## 0.1.6 — 2026-09-07
+
+- **A valid lease token is reused across applies.** Every apply requested a new lease, so a failing deploy
+  retried by the 60 s timer burned tenancy's 5-leases-per-hour budget and then failed on
+  `LEASE_RATE_LIMITED` forever (env-qa-02 pilot). Now: reuse a lease-derived token while `lookup-self`
+  says it is valid; swap the bootstrap token for a lease once; and if tenancy rate-limits the lease while a
+  working token exists, apply with it and defer the swap instead of failing the deploy.
+
 ## 0.1.5 — 2026-09-07
 
+- **`tenancy.port` defaults to 443 everywhere** — the ansible role default and the `TenancyCfg` default now
+  match `install.sh`/`config.example.yaml` (0.1.5 only changed those two); PROTOCOL.md states the intercept
+  port separately from the in-pod 8081, that the broker does not add `#monky-deploy-agent` yet, that the jwt
+  mount keeps no `jti` state, and that `release:gitea` has not run (doc-drift DD-0523/0525/0527/0528).
 - **`${VAR}` inside comment lines is not a reference.** The renderer's `.env.template` header literally says
   "substitutes every ${VAR}", which the refusal check counted as an unresolved variable
   (`ENV_INCOMPLETE: unresolved: VAR`) — the first bundle on env-qa-02 was refused for it.
