Consolidates the last duplicated derivations, and removes the ansible
tree along with the CLI surface that existed only to drive it.
Naming rules:
* agebd/names.py holds ServiceName -- the single definition of how a
service name is spelled in each context: dir_name, module_name,
ioc_name, systemd_unit_name and the case forms. The environment
suffix is deliberately not part of it; that stays a deploy-time
token applied to these base names.
* cli's Service model delegates every name_* property to it, so the
CLI and the CI scripts derive names the same way.
* scripts/ci/service_names.py emits the derived forms as shell
assignments, and deploy-and-restart-service.sh evals them instead of
carrying its own tr calls and its own copy of the systemd naming
convention. Values are shell-quoted, and an invalid name exits
non-zero emitting nothing, so an eval cannot leave empty variables
behind.
Registry lookups:
* agebd.subs.find_service_entry is now the only place that answers
"which registry entry is this service", used by read_ioc_port,
get_ioc_port.py and cli's ServiceRegistry. get_ioc_port.py no longer
parses the registry itself.
* That also settles a semantic split: ServiceRegistry matched names
case-sensitively while read_ioc_port did not. Both now match
case-insensitively via ServiceName, so 'tune', 'Tune' and 'TUNE'
resolve to the same service everywhere.
Ansible removal:
* ansible/ is deleted, along with cli/src/ioc.py, cli/src/core/
ansible.py, the IOC_ENV enum, the ansible and ansible-runner
dependencies, and docs/developer/ansible.md.
* This removes the 'agebd ioc install|start|restart' commands. They
were pure playbook wrappers, so they could not outlive the
playbooks; IOC install, start and restart now have no automation
path in this repo.
bin/start_service.sh keeps deriving its two name forms in bash, with a
comment saying why: it runs on the deploy host before the service venv
exists, so it cannot import agebd. It is the one deliberate exception.
Verified: get_ioc_port.py, cli's ServiceRegistry and agebd's renderer all
return 50007 for 'tune', 'Tune' and 'TUNE'; the shell-emitted names match
the committed on-disk layout for real services including the dashed
OpticsFF-X02S; the CLI runs with only the 'service' command left.

qt/ was declared a render path in step 1 but nothing rendered it: the Qt
deploy step was a plain rsync, so the UI files shipped with literal
placeholders in every PV name.
* deploy.yml renders the deployed qt/ directory with render_subs.py
after the rsync. No --service is needed; qt holds no per-service
token, and a file that acquired one would fail the step rather than
ship the placeholder.
* bin/sls_hla_launch_gui.sh no longer passes an AGEBD_ENV_SUFFIX macro.
No .ui file has referenced $(AGEBD_ENV_SUFFIX) since a06fded, and the
suffix is now baked in at deploy time. This removes the last
hardcoded '-DEV' outside config/environments.yml.
check_ui_files.py is rewritten for the chosen convention. It asserted the
old caQtDM macro, and its regex had stopped matching anything at all once
placeholders appeared in device names -- against the pre-fix Service
Manager it inspected 0 names, where the new check finds 16 violations.
The new rule: every AGEBD- device name carries the suffix token, except
systemd unit names, which are the same in both environments. The token
name is read from the central config so a rename cannot leave this check
enforcing a stale one.
Fixing what that check surfaced, all in A_BD_ServiceManager.ui:
* 16 'IOC=AGEBD-CPCL-<NAME>' caInclude macro values had no suffix. The
included UI uses them as PV prefixes ($(IOC):STATUS, $(IOC):RESTART),
so the dev Service Manager was reading status from, and sending
restarts to, production IOCs.
* Two ssh commands hardcoded sls-vserv-bd-hla01, so the dev GUI's
restart button targeted the production HLA host.
* cli generates those macro values, so the generator emits the token
too and new services are no longer born with the bug.
These were latent while qt/ shipped unrendered placeholders; turning
rendering on would have made them live.
Verified: dev renders -DEV device names and the -dev host, prod renders
byte-identical to the currently deployed prod files, no placeholder
survives in either, and all 24 UI files stay well-formed XML.

Deploy-time placeholders were spread across four independent
implementations: sed in the Gitea deploy script, ansible.builtin.replace
in two playbooks, a hardcoded suffix in bin/sls_hla_launch_gui.sh, and
another in agebd/pv.py. Each defined its own values, so nothing kept them
in sync and a missed substitution failed silently.
Step 1 -- one source of truth:
* config/environments.yml declares every deploy-time token, its value
per environment, and where tokens are allowed to live. An environment
that is missing a token, or defines an undeclared one, is a load-time
error.
* agebd.subs loads it and renders. Rendering is a strict regex over
declared token names rather than a template engine: the rendered
files are EPICS db/substitution files and Qt XML, and an unknown
token must raise rather than survive into the output.
* scripts/ci/check_subs.py enforces the contract in CI: tokens in a
rendered path are declared, declared tokens only appear where they
are rendered or generated, and no pre-migration delimiters survive.
Step 2 -- separate the two substitution stages by delimiter:
* Creation-time (copier, once per new service) keeps {{ token }}.
Deploy-time (every deploy, per environment) becomes @@token@@.
* This drops the {{ '{{ token }}' }} escaping from templates/, which
existed only because one Jinja pass had to emit syntax for a second.
* Angle brackets were tried first and rejected: << >> is not
well-formed XML, and cli parses qt/*.ui with ElementTree.
* The existing sed and ansible consumers are repointed at the new
delimiters so this stays behaviour-preserving. Routing them through
agebd.subs is step 3.
Also fixes, as a side effect of having one implementation:
* The sed pattern '{{ *agebd_env_suffix_upper* }}' quantified 'r'
rather than the space, so it only matched one exact spacing.
* agebd.subs.read_ioc_port compares service names case-insensitively;
ansible/tasks/utils/get-ioc-port.yml still compares CamelCase
registry names against a lowercase input and never matches.
qt/*.ui is declared as a render path but nothing renders it yet -- the
Qt deploy step is still a plain rsync. Wiring that up is step 4.
