A changelog, kept from now rather than assembled at the end

Every version bump gets an entry in the same commit. Not afterwards: the reason
a change was made is known while it is being made and gone a week later, and a
changelog assembled from commit subjects at release time is a list of things
nobody can act on.

Backfilled 0.8.2 through 0.9.8, because those shipped as a running deployment
rather than as releases and 1.0.0's notes have to be assembled from something.

The rule that earns the file its place is the last one in CLAUDE.md: a fix to
something that *looked* like it worked gets a line, always. Those are the
entries somebody stops working around a bug because of, and they are invisible
from outside -- nobody reports a control that silently does nothing, they just
quietly stop using it. Half of what is in here is that shape: a group delete
that left its grants, a share panel that only saved if you also saved the
resource, an update script that stopped after "== fetching ==".

A release is a signed annotated tag whose message is that version's entry, and
that is not decoration -- /admin/updates reads release notes out of the tag
object, so the tag message is literally what an administrator sees on the update
page.

+# Changelog
+
+What changed, per version, for somebody using or running LLeMbas — not a
+restatement of the commit log. If a change fixed something that *looked* like it
+worked, that is worth a line: those are the ones nobody would otherwise know to
+stop working around.
+
+Newest first. Versions are `__version__` in `src/lembas/__init__.py`, which is
+the only place a version is written.
+
+The first tagged release is **1.0.0**. Everything below it shipped as a running
+deployment rather than as a release, and is recorded here so the release notes
+for 1.0.0 have something to be assembled from.
+
+---
+
+## Unreleased
+
+Nothing since 0.9.8.
+
+## 0.9.8
+
+**Updates follow a channel, not a commit.** `stable` tracks the newest `vX.Y.Z`
+tag; `edge` tracks the branch tip. A branch tip is not a release — following one
+means deploying whatever was pushed five minutes ago — so stable is the default
+for anybody who is not the person writing it.
+
+- The Updates page shows a **version** rather than a commit sha: `1.0.0` at a
+  tag, `1.0.0-7-gd4f56d` seven commits past one, and a bare sha only before the
+  first release exists.
+- Release notes come out of the **annotated tag itself**, so no forge API is
+  involved anywhere. That matters: the Gitea API this was checked against
+  returns a 500 from a server-side panic on exactly the releases endpoint.
+- A tag with a suffix (`v1.1.0-rc1`) is deliberately not a release — git's
+  version sort ranks it *above* `v1.1.0`, so accepting one would step a stable
+  host onto a candidate.
+- Fixed: `deploy/update.sh` stopped silently after `== fetching ==` on any host
+  with no release tags — which was every host. Fetched, not reset, not
+  restarted, and no error printed.
+- Fixed: `install.sh` now refuses an `ssh://` repository URL up front instead of
+  letting the clone fail as a service user with no key.
+
+## 0.9.7
+
+**Packaging, and updating without a shell.**
+
+- `/admin/updates`: what is running, what is available, and what changed between.
+  A button applies it — answered by an **opt-in** systemd helper, because the
+  service runs unprivileged and a web application that can restart its own
+  service is one whose worst day is much worse. Without the helper the page says
+  so and prints the command.
+- `Dockerfile` and `docker-compose.yml`. No secret key, no data and no `.git`
+  baked in; loopback only; a TLS proxy expected in front, because a service
+  worker and a microphone both require HTTPS or localhost.
+- `deploy/lxc-install.sh` creates an unprivileged Proxmox container and runs the
+  existing installer inside it.
+- `/healthz`, which opens the database rather than only proving the socket is
+  listening.
+
+## 0.9.6
+
+**Permissions, quotas and sharing.**
+
+- **"What can this account actually do?"** answered on screen, naming *where*
+  each permission came from — admin, the baseline, or a group.
+- Users and groups are list-plus-detail, and membership is edited from **one**
+  side. It was on both, and a save from either overwrote what the other showed.
+- Reading and writing split for notes, memory and skills.
+- **Quotas on a group** — monthly tokens, concurrent replies, agent wall clock,
+  images a day, helpers a reply. Resolved by maximum across a person's groups,
+  with zero meaning *no limit* and winning outright.
+- Fixed: **deleting a group or an account left every share naming it behind.**
+  `forget_principal` had existed since shares did and was called by nobody.
+- Fixed: `library.share` defaulted to off, so sharing shipped documented as done
+  and unreachable — the panel only renders for somebody who holds it.
+- The share panel is its own action with a search box. It used to be checkboxes
+  inside the resource's save form, listing every account on the instance, and a
+  tick only took effect if you also saved the resource.
+- Reports are shareable, and every listing has a **Shared with me** filter.
+
+## 0.9.5
+
+**Extraction settings, embeddings, and hybrid search.**
+
+- `/admin/extraction`: upload size, image edge, JPEG quality, PDF pages,
+  extracted characters, orphan age, extra text extensions.
+- An **embedding model** can be chosen from models flagged for it. Library search
+  then fuses keyword and semantic ranking, so *"how do I get paid"* finds a
+  document that says *"invoicing"*.
+- **Choosing none is not a degraded mode**: no rows written, no requests made,
+  and byte-for-byte the keyword search that was always there.
+- Vectors carry their model and width, and a mismatch is skipped rather than
+  scored — comparing two embedding spaces produces a confident wrong answer.
+- Indexing happens in the background as records are written, with a rebuild
+  button for everything that already existed.
+
+## 0.9.4
+
+**An instance can be somebody else's.**
+
+- Name, tagline, logo, favicon and launcher icons derived from the logo.
+- The Middle-earth wording is editable data. Leaving a box alone does not freeze
+  it, so a later release can still improve the default.
+- **Custom themes** as a set of colours rather than a stylesheet, inheriting
+  whichever built-in they start from.
+- Global CSS overrides, served as `/branding.css`.
+
+## 0.9.3
+
+**Subagents.** A reply can hand a self-contained piece of work to a helper that
+runs on its own and reports back — several at once, so research fans out instead
+of queueing.
+
+- A helper cannot ask questions, cannot send helpers of its own, writes nothing
+  unless the call asked and the chat's mode allowed it, and on a machine runs
+  only a fixed list of read-only commands — in **every** mode, including Auto.
+- Fixed, and it was live in scheduled runs too: an unattended chat that hit an
+  approval built a card nobody could see and sat on it for fifteen minutes.
+
+## 0.9.2
+
+**Image generation defaults an administrator can actually set** — steps, cfg,
+size, sampler, scheduler, denoise, negative prompt, checkpoint, batch. There were
+none: one hard-coded set from the SD1.5 era, and prose in a box as the only way
+to change it.
+
+- The samplers and schedulers ComfyUI had been reporting all along are now the
+  pickers; nothing had ever read them.
+- The tool's own schema restates the instance's defaults, instead of telling the
+  model "Default 512" beside an instance that draws at 1024.
+
+## 0.9.1
+
+**Everything that arrives is announced, not only chat replies.** A scheduled run
+that filed a report used to light a dot in a corner and say nothing.
+
+- A count in the tab title while you are looking elsewhere.
+- **Web push**, so a schedule firing at seven in the morning reaches a browser
+  that is shut. Opt-in per device. It is the one thing here that contacts an
+  outside service, and `services/push.py` says so plainly.
+
+## 0.9.0
+
+**A model can schedule things.** There was no tool for it — asked to "remind me
+every Monday", a model wrote a note and reported that it had scheduled
+something, and every screen agreed with it.
+
+- `schedule_create`, `schedule_list`, `schedule_update`, `schedule_cancel`, over
+  the same rule normaliser the manual form uses.
+- The reply says the resulting timing back in words, which is the only moment
+  anybody can check that Monday was understood as Monday.
+
+## 0.8.3
+
+**An SSH connection may not point at this machine unless an administrator says
+so.** A profile aimed at `127.0.0.1` walked straight past "nothing runs on the
+LLeMbas host" — through a real login, onto the machine holding the database and
+the encryption key. Three positions: off, one named port, or anywhere.
+
+## 0.8.2
+
+- Fixed: **opening the canvas before a chat existed swapped the whole site into
+  the panel.** `hx-get=""` is not "fetch nothing" — htmx looks for the attribute,
+  not the value, so the empty one was a real request for the current document.
+- Fixed: the Canvas and Terminal buttons appeared where they could not work.
+- The bottom edge of the shell is no longer drawn, so the sidebar footer and the
+  composer stop meeting a line at two different heights.
+- Admin pages scroll in one container; `/admin/prompts` no longer drops you at
+  the bottom of a shorter panel.
