ChuckBuildsandClaude Opus 5 6642a78d0e fix(web): ask for the restart that makes an update take effect
The update button pulls new code and restarts nothing. There is no systemctl,
restart, reload or reboot anywhere in the 172-line git_pull handler -- it
stashes, pulls, installs changed requirements, re-removes plugins the user had
uninstalled, and returns "Code updated successfully."

Meanwhile both services go on running the code they loaded at boot. So the
display keeps rendering the old build, the web interface keeps serving the old
build, and the user is told the update worked. Nothing on screen suggests
otherwise, and the next reboot is what actually applies it -- whenever that is.

The affordance for this already exists: the restart-pending banner, raised
after main-config saves, with a Restart Now button wired to the display
service. A code update is a stronger reason to show it than a config save is.

The response now reports restart_required, and applyUpdate raises the banner
with wording for a code update rather than a config save. The banner's message
became a parameter and is persisted next to the flag, since it outlives the
page that raised it.

restart_required is only true when the pull actually moved HEAD. "Already up
to date" is a success too, and prompting after a no-op would train users to
dismiss the prompt unread.

This covers the display service, which is what the Restart Now button drives
and what users notice. The web interface still picks up its own new code on
its next restart; restarting it from inside a request it is serving is a
larger change than this one.

Reverting the flag fails the test that a pull which moved HEAD asks for a
restart. 290 tests pass.

ChuckBuildsandClaude Opus 5 cbfb0e035d fix(web): stop the installer chmod stripping exec bits on every update
git tracks five scripts as mode 644 that first_time_install.sh then chmods to
755 (start_display.sh, stop_display.sh, the two install_*_service.sh, and
one-shot-install.sh does the same to first_time_install.sh). With
core.fileMode true, the default on Linux, git reports all five as modified
from then on, in files the user never touched.

The update button stashes local changes before pulling, so it is not blocked
by this. But it never pops that stash -- stash pop and stash apply appear
nowhere in the update flow -- so the mode change is stashed away and left
there, and the files revert:

    === file modes after the update button's stash ===
      664  first_time_install.sh      <- installer had made these 755
      664  start_display.sh
      664  stop_display.sh
      664  scripts/install/install_service.sh

So every web-UI update silently strips the executable bit from the installer's
own scripts, and leaves a stash entry holding the difference. start_display.sh
and stop_display.sh stop working from the shell afterwards.

A manual `git pull --rebase` over SSH fails outright, since nothing stashes for
it: "cannot pull with rebase: You have unstaged changes". That is the likely
source of the reports, since plenty of people update that way.

Tracking the five as 755 -- what they should always have been, as the
installer chmodding them attests -- removes the spurious mode change
entirely: nothing to stash, nothing stripped, no stash entry, and manual
pulls work.

The pull also passes --autostash, for the case the code explicitly tolerates:
when the stash fails it logs a warning and pulls anyway, and that pull is what
then fails. Autostash also pops what it stashes, which the manual stash does
not.

Note that `git add -A` after `git update-index --chmod=+x` silently reverts
the index to the on-disk mode, so the modes here were set by chmodding the
files themselves.

Regression test asserts the five stay tracked executable; reverting any one
of them fails it.

ChuckBuildsandClaude Opus 5 d2379a1eb6 fix(web): stop /config/secrets handing out every credential it holds
GET /api/v3/config/secrets returned config_secrets.json in full to anyone who
could reach the port, and this interface has no authentication. Probed against
a real rig it produced six populated credential fields: a 40-character GitHub
token, a 183-character Home Assistant token, and Jellyfin and weather API keys.
This is the second door onto the same credentials; #477 closes the first.

Masking the response alone would have been worse than the leak. The only
client fetches every secret, edits one field and posts all of them back, and
save_raw_file_content replaces the file wholesale -- so a masked GET followed
by the client's own save would write the mask over every credential the user
had not touched. That is why this was left open when the leak was found; it
needs both halves.

Read side: mask_all_secret_values(), which already existed for exactly this
endpoint -- its docstring names it -- and had never been wired to a call site.
It leaves empty values and YOUR_* placeholders alone, so a client can still
tell "set" from "not set" without being told the secret.

Write side: strip the echoed mask and blanks from the submission, then merge
onto what is stored, so "unchanged" means unchanged. The cost is that a secret
can no longer be cleared by blanking it; that wants its own affordance, since
a control that erases credentials as a side effect of saving an unrelated one
is not one.

Browser side: the token field is now left empty rather than filled from the
response. Filling it with the mask would have stored eight bullet characters
as the token the next time the user pressed Save, and filling it with the real
value is the thing being fixed. It reports whether a token is saved instead.

Verified end to end through the Flask endpoints, not the helpers. Reverting
the masking fails the leak tests; reverting the merge fails the preservation
tests; both halves are independently guarded. 278 web tests pass.

ChuckBuildsandClaude Opus 5 f0efdafbdb fix(web): stop dumping the config and request headers to the journal
save_main_config logged its entire POST body and the full request headers at
ERROR on every save. The body is the configuration itself, and the headers
carry the session cookie, so a routine settings change wrote both to the
journal -- at a level that guarantees they survive any sane log filter.

The lines are leftover debug output: they say "DEBUG:" in the message while
calling logging.error, and they went through the root logger rather than the
module logger, bypassing the level configured for this blueprint.

Replaced with a debug-level line recording the shape of the request, which is
the part with diagnostic value. The local `import logging` went with them; it
shadowed a module-level import that was already there.

ChuckBuildsandClaude Opus 5 95bd8a1a67 fix(web): stop an unrelated config edit from erasing a plugin's secret
Saving any field on a plugin's config form destroyed that plugin's stored
credential. On a rig with a weather API key, changing the city silently
emptied the key, and the plugin stopped working at the next fetch with no
indication why.

The path had no guard at any step. The config partial masks secrets before
rendering (pages_v3.py:740), so the browser posts them back blank; _parse_value
deliberately preserves "" for optional string fields; separate_secrets routes
that "" into secrets_config, which is a truthy dict; deep_merge writes it over
the stored value; save_raw_file_content persists it.

The blank does not even need the round-trip. merge_with_defaults injects the
schema's api_key default ("") into every save, so a client that never sends
the field at all still erases it. test_secret_count_message_counts_top_level_keys
was counting exactly that injected blank as a saved secret field -- the visible
edge of the bug, pinned as expected behaviour.

remove_empty_secrets() already existed for this, with seven unit tests and a
docstring describing this precise scenario ("clients will send those empty
strings back ... so that existing stored secrets are not overwritten with
blanks"). It was never wired into a call site. This wires it into both save
paths that merge into the secrets file.

A blank now means "unchanged" rather than "delete", which is the same contract
the helper's tests already describe. The cost is that a secret can no longer be
cleared by emptying the field; clearing needs its own affordance, since a
control that erases credentials as a side effect of ordinary edits is not one.

Verified by reverting the guard: the new round-trip test then fails with the
stored key read back as ''. 262 web tests pass with it.

ChuckBuilds fc6104f229 fix(web): stop /config/main handing out every credential it holds
The endpoint returned the raw config to anyone who could reach the port, and
this web interface has no authentication of any kind. An unauthenticated
request against a live rig returned:

    github.api_token                40 chars
    incoming-packages.ha_token     183 chars
    jellyfin-now-playing.api_key    32 chars
    ledmatrix-weather.api_key       32 chars
    on-air.mqtt_password             8 chars
    youtube.api_key                 20 chars
    youtube-stats.api_key           39 chars

A GitHub token and a Home Assistant long-lived token among them. Anything on
that LAN could read them.

The x-secret masking the plugin config endpoints use does not reach here: this
route never consults a schema, and core keys such as github.api_token have no
schema to carry the marker. Several of the fields above *are* tagged x-secret
in their plugin's schema and were still returned in full, which is what rules
out the schema route as the fix for this endpoint.

Credential-named fields are now blanked. Matching on the name is blunt, and
for a whole-config dump that is the right default: anything named like a
credential should not leave the process, and a new plugin adding a
differently-shaped secret is covered without anyone remembering to tag it.

Blanked rather than removed, and safe to blank: POST /config/main merges into
the freshly loaded config and writes only the keys it was given, so a client
that round-trips this response cannot erase a secret it never saw. The web API
suites confirm it -- 81 passing, unchanged.

On the test that matters: the first version of this suite exercised the two
helpers and nothing else, and reverting the single line that wires the
redactor into the route passed all thirty of them. A property asserted on a
helper is not a property asserted on the endpoint, and it is the endpoint that
is exposed to the network. The added test goes through the view function, and
it does fail on that revert.

This also corrects an earlier claim of mine. I reported that GET /api/v3/config
did not expose these values; that path 404s, so the check proved nothing. The
real route is /config/main and it exposed all of them.
