They were hard-wrapped at 80 characters, broke mid-parenthesis, and spent lines
restating what the code below them does.
Rewrapped at natural boundaries instead, with the narration dropped and only the
reasons, gotchas and surprises kept. Section dividers stay - they delineate long
plays rather than narrate them.
Comments only; no scenario behaviour changes.

Hookshot is the widest HTTP surface of the bridges here - an appservice port
plus a `listeners` list whose entries appear or vanish with independent
switches - so the scenario asserts on that surface rather than on "it started".
The scenario configures NO third-party service. GitHub, GitLab, Jira and Figma
each need an account and a credential somewhere else, which is where a scenario
stops testing this repository (docs/molecule-testing.md). GitLab, which the role
turns on by default, is switched off and its absence from both config.yml and
the registration's namespaces is asserted. The generic webhooks listener needs
no credential from anyone, and is what gets exercised live: a POST to an unknown
hook id comes back as `{"ok":false,"error":"Webhook not found"}`, which only
Hookshot's own generic-webhook handler produces - an Express "Cannot POST" page
there would mean the port is Hookshot's but the service was never mounted on it.
Every port the scenario sets differs from both the role's default and Hookshot's
own, and the run asserts both halves: the webhooks, metrics and appservice ports
it chose all answer, and 9000/9001/9003/9993 - what the role would have used
instead - all refuse. Metrics are off in the role's defaults, so that listener
exists only because the scenario asked for it, and /metrics answers with
`hookshot_*` series that nothing else could have produced.
config.yml and registration.yml are parsed as YAML and asserted structurally, so
a value landing under the wrong key cannot pass as a substring match.
Two things the role made necessary:
- `tasks/main.yml` opens with a block tagged `reset-hookshot-encryption`, and
Ansible runs tagged tasks unless tags are actually selected - so any tagless
play hits it, and it stops `matrix-hookshot.service` before that service
exists. The scenario skips the tag, which is what the playbook effectively
does by always running with `--tags=setup-all,start`.
- The role reads `matrix_host_command_openssl`, which matrix-base defines.
matrix-bridge-appservice-irc reads it too, so it goes in the shared playbook
context rather than into this scenario.
Falsified by pointing the webhooks listener at 127.0.0.1 in the role's config
template - a change no file-level assertion can see. Every config and
registration assertion still passed, and the run failed at "Assert the generic
webhooks service is mounted on that listener" with "Port 9741 did not answer as
Hookshot's generic webhooks service". Reverted afterwards.

The third shape: a non-mautrix bridge. It confirms the scaffolding is not
mautrix-specific, and it is laid out differently enough to be worth having -
everything sits directly under the base path rather than in config/ and
data/ subdirectories, the owner and homeserver URL are passed on the command
line rather than through a config file, so the unit is where they can be
checked, and identd optionally binds host port 113.
matrix-base's matrix_server_fqn_* family moved into the shared context;
18 of the roles here read one of them.
Three roles now, three shapes - HTTP receiver, mautrix bridge, non-mautrix
bridge - and the scaffolding took no per-shape special-casing beyond each
role's own variables.

The second scenario, chosen to be a bridge rather than another HTTP
component: bridges are roughly 40 of the 70 roles here, and validating the
shape on role two is cheaper than discovering it on role forty. It found
two things the first role could not.
Bridges read a whole family of variables from outside themselves -
matrix_bridges_relay_enabled, _encryption_enabled, _encryption_default,
_msc4190_enabled, _self_sign_enabled, plus matrix_admin - all defined in
matrix-base. Since every bridge reads them, they belong in shared context
rather than in each bridge's scenario: molecule-shared/playbook-context.yml
now carries them along with the identity and path variables the first
scenario had inline. Note it is loaded through vars_files, which outranks
inventory group_vars, so it is authoritative; a scenario that wants to prove
one of these reaches the rendered configuration should say so explicitly.
Appservices call /whoami while starting and refuse to run if the id returned
is not the bot user they were configured as - mautrix-whatsapp exits 17 with
"Unexpected user ID in whoami call". The shared stub now takes the id it
should claim to be. Expect every bridge and bot to need this.
What the scenario proves: the bridge starts and stays up, opens its
appservice port, its rendered config and appservice registration carry the
scenario's tokens and bot user, it created its sqlite database under the
role's data path as the role's uid, and it runs the version the role pins.
It does not bridge anything and never will.
