ScreenTinker 04e0e8fdf4 Measure and thumbnail an image from a single decode
Ingest asked for metadata() then writeThumbnail(), which decoded the file twice.
That pairing was free under sharp, whose .metadata() only parses the header, but
every decode here is a full one — ~1s for a 12MP photo — so the naive translation
doubled the most expensive thing on the ingest path.

image-ops.measureAndThumbnail() returns both from one decode. Full ingest of a
12MP photo: 2 decodes/~1.9s -> 1150ms, still with zero event-loop stalls.

The subtlety is the failure contract. In the two-call version width and height
were assigned BEFORE the thumbnail was attempted, so a failed thumbnail still left
usable dimensions on the row — the player needs them to letterbox. Merging naively
would have turned any thumbnail failure into total metadata loss. So a WRITE
failure is reported ({thumbnailWritten:false, thumbnailError}) with the dimensions
intact, and the caller sets thumbnail_path only when the write succeeded, keeping
the phantom-path discipline. A DECODE failure still throws — there is nothing to
report about an unreadable image.

backfill-rotation-dims.js deliberately keeps the separate calls: it probes every
image row but regenerates a thumbnail only for the few whose dimensions changed,
so pairing them there would decode files it has no reason to thumbnail.

Tests count decodes rather than timing them — an exact property, and a wall-clock
comparison would be flaky under load. The count filters for reads of the file under
test: Node's ESM loader also goes through fs.promises.readFile, so a raw call count
picks up jimp's and the WASM codecs' lazy loading and reads 30 instead of 1.

1649/1649 pass. Ingest re-verified across all 7 formats with sharp moved aside.

ScreenTinker 5171f09f96 Run image decoding on a worker thread
Fixes the blocker the previous commit shipped with. Pure-JS decoding costs ~1s of
solid CPU for a 12MP photo, and in-process that is not a slow upload but a stalled
event loop — no heartbeats, no socket traffic. thumbnail-backfill.js walks a whole
library at boot, so it reproduced #240 (blocked loop -> missed heartbeats -> panels
offline -> reconnect churn) from our own maintenance. sharp never did this because
libvips works on a threadpool.

image-ops.js is now a dispatcher over image-ops-worker.js; the work moved unchanged
to image-ops-core.js, so callers and their failure contract are untouched.

Measured on a 12MP photo: 1079ms wall with the loop stalled 1003ms, to 1881ms wall
for two ops with ZERO stalls and 185 timer ticks serviced. Wall time is worse and
that is fine — it is off the main thread now.

Design notes, all load-bearing:
  - ONE JOB AT A TIME. A decoded 12MP bitmap is ~48MB of RGBA; overlapping jobs
    multiply peak memory by queue depth, which is the wrong failure on the small
    targets this change exists to reach. Costs no throughput — the work is CPU-bound
    and one busy worker already saturates its core.
  - unref'd while idle, ref'd only in flight. Otherwise scripts/backfill-rotation-
    dims.js never exits and `node --test` hangs forever. Verified: a CLI-style run
    exits in 104ms, code 0.
  - decode failures reply as messages, so one bad upload cannot tear down the worker
    and take unrelated queued jobs with it.
  - in-process fallback if a thread cannot be had, warned rather than silent.

test/image-ops.test.js pins the loop-liveness property, which no functional test
would catch. Its thresholds were mutation-tested against the inline path: the first
version passed there too (4MP stalls only ~355ms, under a non-flaky threshold), so
the fixture is 12MP and the thresholds sit in the gap between the two behaviours —
worker ~90 ticks/~0ms, inline ~3 ticks/~897ms. It now fails inline, as a guard must.

1647/1647 pass. Ingest re-verified with node_modules/sharp moved aside.

ScreenTinker 260a0ca4b8 spike: replace sharp with pure-JS image ops (jimp + jsquash WASM)
Removes the last native dependency from the ingest path, so the server no longer
needs a per-platform/per-ABI prebuilt to thumbnail an image. Motivated by getting
the server onto hardware with no toolchain, but the ABI tax is paid on every
install — it is the same failure class lib/preflight-deps.js exists to explain.

lib/image-ops.js is the whole surface: metadata() and writeThumbnail(), which are
the only two things ingest ever asked sharp for.

Format parity holds. jpeg/png/gif/tiff/bmp are native to Jimp; webp and avif go
through @jsquash WASM, whose bundled .wasm must be compiled by hand because the
packages locate it with fetch(file://) and Node has no file:// fetch — the only
symptom otherwise is a bare "fetch failed". heic is unsupported, as it already
was: sharp advertises heif but its prebuilt libvips refuses HEVC.

#170 is preserved by a different mechanism. Jimp applies EXIF orientation at
decode and rewrites the tag to 1, so metadata() reports display dimensions and
imageDisplayDims() runs as a no-op instead of swapping W/H a second time. The
helper stays in the path so the rule keeps living in one place.

Verified: 1643/1643 tests pass, and ingest was exercised in a child process with
node_modules/sharp moved aside — jpeg, EXIF-rotated jpeg, png, webp, avif, gif
all measured and thumbnailed correctly, corrupt input still yields nulls with no
phantom thumbnail_path.

KNOWN BLOCKER, do not ship as-is: Jimp is pure JS on the main thread, where sharp
handed work to a libvips threadpool. A 12MP photo goes 65ms -> 1079ms, and the
event loop stalls for 1003ms of it (sharp: zero stalls). thumbnail-backfill.js
walks a whole library at boot, so this reproduces #240 exactly — blocked loop,
missed heartbeats, panels marked offline, reconnect churn. Needs a worker_thread
offload before this is viable; image-ops.js is the seam for it.

ScreenTinker e5e5b75b85 Customer Entra tenants: verify the domain, then be believed
The previous fix let the instance-wide Microsoft button work and left the
customer-facing path broken, which is the worst way round. An organization that
brings its own Entra tenant would publish the TXT record, watch its domain go
green, and still be refused at login with `email_unverified` -- because Entra
sends no such claim and rowToProvider pinned the assumption off for every org
provider.

Requiring a claim Microsoft does not emit is not a security control, it is an
outage. What makes it safe to stop requiring it is the proof that already gates
these providers: the callback confines an org provider to its DNS-verified
domains, and an address only reaches the check after passing that. Whoever
controls a domain's DNS controls its mail, which is the same trust that makes a
verification link meaningful.

So the assumption is DERIVED from proof -- `verified.length > 0` -- rather than
pinned off. A provider that has verified nothing still assumes nothing, which is
belt and braces: emailAllowedForProvider already refuses it, since an empty
allow-list matches no domain, but deriving it here means a future reordering of
those checks cannot silently widen it.

It is never a column, and there is no column for it to be read from. An
organization must not be able to switch this on for itself; it is a consequence
of DNS proof, not a setting. A test asserts both -- that the value is derived
next to `source: 'org'`, and that no `assume_email_verified` exists in the
schema.

Domain confinement is untouched. An explicit `email_verified: false` is still
refused from anyone.

Mutations all fail the tests: assuming unconditionally, never assuming, and
reading it from the row.

ScreenTinker b1a58144bb Microsoft sign-in could never complete: Entra omits email_verified
The OIDC callback required `claims.email_verified === true`. Entra ID v2 does
not send that claim at all, so every Microsoft login authenticated correctly
against the tenant and was then refused with `email_unverified` on the way back.
Nothing caught it: the SSO tests assert how the Microsoft issuer string is built
but never put a Microsoft-shaped token through the policy.

The strict check was itself a fix -- `=== false` had been accepting an omitted
claim -- and it is right for a provider a CUSTOMER configured, since such a
provider is chosen by the party it vouches for and its bare assertion is worth
nothing. What was wrong is treating that as a question about the token when it
is a question about who we trusted. `users.email_verified` is our own state; the
claim is the IdP's. An instance-wide provider was chosen by the operator -- the
same trust that already exempts it from domain confinement -- and Microsoft is
additionally pinned to one tenant GUID, so only that directory can issue a token
whose `iss` matches.

So the policy now depends on the provider, in emailIsVerified(), next to the
flag it reads so the two cannot drift:

  - explicit true            -> believed, from anyone
  - claim absent, operator   -> believed (Microsoft; opt-in for other IdPs)
  - claim absent, org        -> refused
  - explicit false           -> refused, always

Org providers pin the flag false in rowToProvider and never read it from the
row, so the takeover path the strict check existed to close stays closed.
Google is left strict: it does send the claim.

Also documents MICROSOFT_CLIENT_SECRET (supported in code, missing from the
table), that the redirect URI must be registered under Web rather than SPA, and
the email optional claim -- the other two ways an Entra setup fails.

All three mutations of this policy fail the new tests: reinstating the strict
check (3 failures), letting an org provider assume (1), and accepting an
explicit false (2).

ScreenTinker 85febe05c0 Fix a login-page dead end, an enumeration oracle, and three boot/limiter defects
From the regression sweep. The first is a genuine regression against main.

A RATE-LIMITED DISCOVERY PERMANENTLY DEAD-ENDED THE LOGIN PAGE

lookupOrgSso checked that a body PARSED, not that the request succeeded — and a 429
body is valid JSON. So `data.sso` came back undefined, the single sign-on button was
hidden, the password box restored, and the domain recorded as answered: permanently,
for the life of the page. On an SSO-only domain that is the worst outcome available —
the password box then returns 403 and the button the user is told to use is not on the
screen. Discover is 10/min per IP and one person filling in the form costs up to four
calls, so a few colleagues behind one office address is enough. The comment above that
code already claimed to prevent exactly this; it only ever covered the 5xx case.

THE SSO-ONLY REFUSAL WAS AN ACCOUNT-EXISTENCE ORACLE

403 for an address that exists, 401 for one that does not — from an endpoint whose own
lockout returns 401 specifically to avoid that. The DOMAIN check now runs BEFORE the
account lookup, so both answer identically; whether a domain uses single sign-on is
already public through /sso/discover, so it reveals nothing new. The membership-level
refusal is deliberately downgraded to the generic 401, because a distinct answer there
would put the oracle back for exactly the accounts worth enumerating.

Verified: existing and invented addresses at an SSO-only domain both 403; and on an
instance with NO SSO configured, register/login/wrong-password/unknown-address are
201/200/401/401 — the hoisted check does not touch them.

BOOT PREFLIGHT

  - a cold install ran `npm ci --omit=dev` unconditionally, so a first start on a
    developer machine left `npm test` broken: same class of surprise as the prune this
    file already warns about, through the other branch of the same if. Now production-
    only.
  - two servers starting together: the loser died with ENOTEMPTY even though the tree
    was complete by then. It re-checks before failing.
  - the opt-out accepted only '1', unlike every other boolean the server takes.

THE LIMITER FOLD, DONE PROPERLY

Unmatched paths under /api/organizations still minted a bucket each. My first fix was a
catch-all regex — which put every unknown path in ONE bucket WITH the real endpoints,
so flooding nonsense URLs exhausted the limit for /sso-only. That trades a bypass for a
denial of service. Folding is now by explicit shape: known endpoints keep their own
keys, everything else shares a bucket kept apart from all of them.

Verified: 120 unmatched paths give 60/60 (bypass closed), and after that flood
/sso-only, /sso and /sso/:id/test all still answer 401 rather than 429 (no starvation),
while 70 hits on one real endpoint do trip its own limit. The login trailing-slash
bypass stays closed.

1609 tests, three clean runs.

ScreenTinker 37e22bb773 SSO-only: enforce per-domain, cover invited members, and stop the admin locking themselves out
A second attack round defeated three of the previous fixes and found a regression I
introduced. Each is reproduced-then-refused against a live server.

MEMBERSHIP: organization_members IS NOT HOW PEOPLE JOIN

Only three places write that table and nothing deletes from it — every INVITED user,
every admin-created account and every workspace assignment lands in workspace_members
and nowhere else. So keying enforcement on organization_members covered org owners and
people who had already used SSO: exactly the set the domain check already caught. A
reviewer invited an outside address into an SSO-only tenant, kept password login, read
the member list and content, and used it to invite more. Enforcement now asks whether
the user is in ANY workspace belonging to an SSO-only organization.

THE INTERLOCK ASKED THE WRONG QUESTION, TWICE

It fired only when a domain list became EMPTY, and it counted PROVIDERS. So:
  - replacing acme.test with decoy.test removed every proof and sailed through — two
    PUTs, and the customer's domain enforced nothing, with sso_only still reading true;
  - with two providers you could disable the one owning your staff's domain, because
    the other one, covering a domain nobody signs in at, still "enforced".
The question that matters is per-DOMAIN: after this change, is every domain that
enforces today still enforcing? Losing one needs the operator, whichever route gets you
there. The refusal now names the domain that would stop being covered.

REGRESSION I CAUSED: THE HAPPY PATH LOCKED THE OWNER OUT

Sign up with a personal address, create the org, verify the company domain, turn this
on — and enforcement covers you (you are a member) while your own address is outside
the verified domains, so passwords are refused AND your org's provider will not assert
for you either. No route removes a membership; reset succeeds but login still refuses.
Recovery meant a platform admin turning SSO off for the whole tenant. Enabling now
refuses when the actor's own address is not covered, naming it, and REPORTS everyone
else who will be stranded instead of letting them be discovered by support ticket.

ALSO

  - POST /api/admin/users gated only on the target workspace, so you could mint
    cfo@theircompany.test into your OWN workspace: login refused, but the row now has a
    password_hash and an SSO login will not adopt one — permanently locking a real
    person out of their own address. Now gated on the address's domain too.
  - `ceo@acme.test.` (trailing root dot) slipped the registration gate.
  - two rate-limited sub-paths were still unfolded because the generic org-id fold ate
    `sso-only` as an organization id; the specific shapes are matched first now.

1609 tests, three clean runs. Verified live: invited outsider 403, swap refused,
sibling-disable refused, squat 400, self-lockout refused with the address named, and an
on-domain admin gets `stranded_members` back.

ScreenTinker 983bee31b7 SSO-only: close the backdoor, the unilateral disable, and the fresh-install fail-open
Three HIGH findings from the QA round. Each was demonstrated end to end against a
running server, and each is now refused there.

ENFORCEMENT PROTECTED A DOMAIN, NOT AN ORGANIZATION

ssoOnlyForEmail answers about an address's domain, so any account in the tenant at an
outside address kept password login — a contractor, an MSP, the one address nobody
remembered. And it could be manufactured: POST /api/admin/users accepts workspace_admin
and creates a LOCAL password account at any address bound to that workspace. A review
created backdoor@notacme.test, logged in with the password, landed in the SSO-only org,
and used it to create another. Enforcement is now keyed on MEMBERSHIP as well as domain
(ssoOnlyForUser), and that route refuses to mint password accounts into an SSO-only
organization at all. platform_admin keeps both, as the operator break-glass.

THE APPROVAL WORKFLOW WAS DECORATIVE

`sso_only` is honoured only while a provider is enabled and a domain is verified, so
`PUT {enabled:false}`, `PUT {email_domains:""}` and `DELETE` each switched enforcement
off — with sso_only still reading true, no request filed and the operator never told.
The delete variant additionally rewrites every federated account to `local`, after
which a password reset takes over accounts the identity provider was supposed to own.
Anyone who could file a request could simply turn the provider off instead. All three
now refuse with sso_only_locked when nothing else would still enforce, and say to ask
for approval.

FRESH INSTALLS FAILED THE MIGRATION AND FAILED OPEN

The ALTER adding organizations.sso_only sat in the column-migration array, which runs
BEFORE the multi-tenancy migration that creates the table: `[migrate] FAILED … no such
table: organizations`, one line among ~85. The instance then ran its whole first boot
with the SSO settings screen 500ing and ssoOnlyForEmail catching `no such column` and
answering "not required" — password login proceeding for an organization that had
switched it off. It self-healed on the second boot, which is what made it easy to miss.
The column is now added after the table exists, and the catch distinguishes "this
instance has no per-org SSO" (null, so single-tenant installs keep working) from drift
on a table that DOES exist (throw). Login treats an undeterminable answer as "required"
rather than letting a 500 escape or letting the login through.

Verified live, all four refused with enforcement intact and the operator still able to
sign in. 1609 tests pass.

ScreenTinker 901e664591 Fix: the router discarded every SSO return, so single sign-on could never complete
THE CRITICAL ONE. The server ends every SSO login by redirecting to `#/login?sso=1`
(claim the session) or `#/login?sso_error=<code>` (say what went wrong). The router
compared the hash EXACTLY against '#/login' in three places, so an unauthenticated
browser — the only kind that ever arrives there — had the hash rewritten to a bare
'#/login' and the query was gone before the login view ran.

  - a user who authenticated perfectly at their IdP landed back on a clean login page,
    still signed out, with no message: /api/auth/sso/claim was never called
  - all 16 error codes rendered SILENCE — not a raw key, not "undefined", nothing to
    report or search for
  - it took the pre-existing ?verified=1 email-verification toast with it

The comment above the reset-password exclusion describes this exact bug class and was
never extended to the login route. It is now, in all three places: the auth redirect,
the render dispatch, and the no-workspace guard.

Verified in real Chrome: 16/16 codes render a real sentence, and ?sso=1 now reaches
POST /api/auth/sso/claim.

Also, on a server with NO SSO configured, confirmed in the browser that the login page
is exactly what it was before any of this work: email, password, Sign In, Forgot
password, zero SSO buttons, no single sign-on wording, plain local login issues a
session, no page errors.

And fixes MY preflight, which pruned devDependencies as a side effect of BOOTING:
`npm install --omit=dev` reconciles the whole tree, so merely starting the server
deleted socket.io-client, puppeteer-core and js-yaml and broke `npm test`. A reviewer
watched it happen. It now installs only the named missing packages, with --no-save —
a boot-time repair that quietly removes packages is worse than the failure it fixes.

ScreenTinker 601b526264 Boot: install missing dependencies and rebuild the native module before starting
scripts/upgrade.sh already runs `npm ci`, so this is not for the normal path. It is
for the ways a box ends up with the wrong node_modules, both of which present as
"server will not start" with an error naming a file rather than the action needed:

  ROLLBACK      checking out an older tag to back out a bad release restores that
                tag's package.json but not its packages. This branch removes
                google-auth-library, so a rollback to main would not boot — and you
                are rolling back because something else already broke.
  NODE UPGRADE  better-sqlite3 is compiled against one ABI. Upgrading Node makes every
                boot fail with NODE_MODULE_VERSION, which reads like database
                corruption and is not.

Runs as the FIRST statement in server.js, before any dependency is required, and uses
only Node builtins — anything it imported could be the thing that is missing. Repairs
with `npm install --omit=dev` (never `ci` on a partly-populated tree, which would
delete a working node_modules to fix one package) or `npm rebuild better-sqlite3`, and
exits with the command to run if it cannot. ST_SKIP_DEP_PREFLIGHT=1 opts out.

⚠️ The first version of the native check was WRONG and I caught it only by running it
under a real version mismatch: better-sqlite3's entry point is plain JavaScript that
loads the compiled binding lazily, so `require()` succeeds under a Node the binary was
never built for. It reported a genuinely broken install as healthy. It now opens an
in-memory database, which is what actually pulls the binding in. A test pins that,
because the failure is invisible — the check keeps passing on every machine where
nothing is wrong.

Verified: a deleted dependency is detected, installed and the server boots (200); the
ABI mismatch is detected under Node 18 against a module built for Node 20 and reported
clean under Node 20; a healthy tree costs 8ms and touches no network.

1609 tests pass.

ScreenTinker 0e8ffa5444 SSO-only: an org may require its own identity provider, operator approves removal
Per-organization toggle. Enabling is the safe direction and an org admin does it
alone; turning it back off is a REQUEST that a platform admin has to approve, because
that is the direction that re-opens password sign-in — the direction a compromised
admin would take, and the one a customer will demand at their worst moment with the
IdP down.

  - requires at least one VERIFIED domain, so nobody can lock a company out of a
    domain they only typed, and an org cannot leave its own people with no way in
  - the login page HIDES the password field for those domains rather than letting
    someone type a password that will be refused and then go reset it
  - the refusal is `sso_required`, distinguishable from a wrong password
  - the approval email carries NO action link: a token that acts on its own turns
    every forwarded copy into a way to switch off a customer's SSO. The decision is
    made signed in as a platform admin.

INSTANCE PROVIDERS WERE A SIDE DOOR

Blocking passwords while leaving "Continue with Google" is not requiring single
sign-on, it is renaming the bypass — instance-wide providers are the operator's and
are NOT domain-confined, so one could assert an address at an SSO-only domain and walk
straight past the customer's MFA and deprovisioning. The callback now refuses any
provider other than that organization's own, and the page stops offering them.

Instance-wide stays the default everywhere else: an address whose domain has no org
SSO still gets local plus every configured instance provider. The org only overrides
for its own verified domains.

PLATFORM_ADMIN IS EXEMPT, DELIBERATELY

The operator approves turning this off. If the operator's own address sat at an
SSO-only domain and that IdP broke, nobody could sign in to approve anything and the
instance would be bricked. The exemption is the break-glass, and a test pins it as
source so it is not "tidied away" as a convenience.

BROWSER-FOUND

Hiding the password by hiding its .form-group also hid the organization SSO button,
which lives inside that same group — leaving a login page whose only action was
"Create Account". Only visible by looking at a screenshot. Hides the field now, not
the container.

Player untouched: this branch changes no device, WebSocket or provisioning file, and
the 358 device/player/socket/pairing tests pass.

1603 tests pass. Enforcement, the approval workflow and the login page verified in
real Chrome.

ScreenTinker c91b96ab91 SSO: refuse delegated proof names, release lapsed and deleted claims
Third review pass. It confirmed the crash wrapper holds (~13,000 hostile requests,
no fourth crash), the SSRF rewrite holds (77 vectors, every CIDR boundary proven),
the rate-limiter rewrite closed the login brute-force bypass, and /sso/claim rejects
every wrong token kind. It also found that two things I built yesterday did not do
what they claimed.

THE 8-HOUR LIMIT DID NOT BOUND SQUATTING

Pressing Verify on an expired claim REISSUED it in place, renewing the clock — so one
request per window held a domain forever, through the endpoint meant to enforce the
limit. Worse, a renewal was not a new claim, so the operator was notified exactly once,
on day zero: a tenant could sit on a company's domain for a year off a single stale
alert. A lapsed claim is now RELEASED. Re-adding it is an ordinary new claim: new
token, and the operator is told again. Squatting is not impossible; it is loud.

A DELEGATED PROOF NAME COULD FORGE A DOMAIN

A TXT lookup follows CNAMEs, and RFC 4592 means a wildcard `*.victim.com` synthesizes
`_screentinker-verify.victim.com` too — so a wildcard CNAME let whoever controls its
target prove a domain they do not own, turning an ordinary subdomain takeover into
every `@victim.com` login. A reviewer did this against a real authoritative zone. The
proof name is now refused if it is a CNAME, which is stricter than ACME's dns-01, and
the comment that claimed wildcards "cannot be mistaken for a proof" — true only for
wildcard TXT — has been corrected.

MY VERIFY BUTTON REPORTED FAILURE ON SUCCESS

`await load()` — the loader is `loadSso()`. The ReferenceError went into a bare catch,
so a correct DNS proof showed "Could not verify that domain" and left the card stale.
On the expired branch the admin kept publishing a token the server had already rotated.

ALSO FIXED

  - deleting a provider stranded its verified domains (no FK, UNIQUE, never expires) so
    the domain was blocked for EVERY org forever with no in-product recovery, and its
    users could neither sign in nor reset. Delete now releases the domains and returns
    the accounts to local, in one transaction; a cascade FK backstops it.
  - isOrphanedFederated read absence-of-config as proof-of-deletion, so unsetting
    GOOGLE_CLIENT_ID made every Google account password-resettable instance-wide, and
    irreversibly. Restricted to org-provider slugs.
  - `email_domains: null` (not undefined) took the destructive branch and deleted every
    DNS proof an organization had.
  - unbounded domain lists: 400 domains sent 401 emails; now capped at 50, one digest
    per save, and /api/organizations is rate-limited at all for the first time.
  - login and register responses carried password_reset_hash and email_verify_hash —
    live account-takeover credentials handed to the browser. One sanitiser now.
  - trailing-dot hostname (`https://localhost./`) slipped the SSRF guard.
  - asyncRoute's own catch could throw and kill the process it exists to protect.
  - a legacy DB whose typed domains were never verified now says so LOUDLY at boot
    instead of silently locking every federated user out.

TESTS

Two of the previous round's tests passed against the code they were named after: one
asserted UNIQUE against the test harness's own CREATE TABLE rather than the shipped
schema, the other used two different domains so no ordering was exercised. Both
replaced and confirmed load-bearing. Seven mutations now turn the suite red, including
removing the CNAME refusal, the verified_at filter, and the expiry itself.

1598 tests pass. Delete-release, lapse-release and the leak fix verified against a

ScreenTinker 9155370ae8 SSO: TXT only for domain proof, drop the CNAME form
The CNAME alternative pointed at `<token>.verify.screentinker.com`. Making that work
means operating a wildcard DNS zone that answers for every token ever issued — which
this project does not have, so half the published instructions described a check that
could never pass. Documenting a verification path that cannot succeed is worse than
offering one form.

TXT needs nothing outside the customer's own zone, and the dedicated `_`-prefixed name
keeps it away from the apex where SPF and DMARC live. A wildcard `*.example.com` cannot
be mistaken for a proof either way: it answers with its own value, never the token, so
it lands in "exists but does not match".

Also simplifies check() — one lookup, no Promise.allSettled, and NXDOMAIN is reported
as "not published yet" rather than as an error.

ScreenTinker d4b8d7dad4 SSO: prove domain ownership by DNS, and fix what the second review found
A second review pass, run against the previous commit, found four blockers — two of
them introduced by the fixes in that commit. It also confirmed the original account
takeover is closed: a hostile IdP with real TLS, discovery, JWKS and RS256 driving the
real routers now stops at domain_not_allowed, and all 16 bypass variants are refused.

DOMAIN OWNERSHIP (the root cause, not the symptom)

A claimed domain used to mean "nobody else claimed it". It now means the organization
published a record in that domain's own DNS — TXT or CNAME, at a dedicated
_screentinker-verify name rather than the apex, where an edit would sit beside SPF.

  - an unverified domain routes NOBODY and cannot be asserted; it reserves the name
  - an unverified claim LAPSES after 8 hours, so a domain cannot be held against its
    real owner, and lapsing rotates the token so a record left over from an abandoned
    attempt cannot satisfy a later claim
  - a verified domain never expires — re-proving on a timer would log a customer out
    over a DNS edit made months later
  - routing and confinement read the VERIFIED set only, never the typed column
  - configuring SSO now requires a verified email address
  - platform admins are emailed when a domain is claimed; nothing is ever sent to the
    claimed domain, which would let any tenant make this product email third parties

Instance-wide providers are exempt from all of it: they are the operator's own
configuration and keep the trust they have always had.

BLOCKERS FROM THE REVIEW

  - two unauthenticated remote crashes, both one request, both "async handler throws
    before its try": `Cookie: st_oidc_tx=%` (unguarded decodeURIComponent) and the
    fail-closed secret added last commit, which turned a JWT_SECRET rotation into a
    permanent crash loop. Fixed the CLASS with asyncRoute() rather than the instances.
  - the SSRF guard was bypassable via IPv4-mapped IPv6 ([::ffff:127.0.0.1]) and also
    refused every host beginning "fc"/"fd" (fcm.googleapis.com). Addresses are now
    parsed and compared by RANGE. 42 cases verified.
  - the takeover fix had NO test — the test named after it asserted two struct fields
    and passed with the guard deleted. The decision is now a pure function and four
    mutations were confirmed to turn the suite red.
  - the PUT path never received the TOCTOU fix, so two orgs could end up holding one
    domain and forEmail handed routing to the attacker's older row.

ALSO

  - linking compared slugs, so an org could never rotate its own IdP, and fell open on
    an empty auth_provider. It now asks which ORGANIZATION owns the slug.
  - an account stranded by a deleted provider can be reclaimed by password reset —
    proof of the mailbox, which is stronger than the IdP assertion that created it.
  - /sso/claim accepted a pre-TOTP mfa_pending token and returned the full user row;
    it now takes a purpose-built 120s claim token with a pinned algorithm and typ.
  - the rate limiter keyed on a caller-controlled path, so a trailing slash bought a
    fresh bucket — a real login brute-force bypass.
  - domain_not_allowed and account_exists_other_provider rendered as "please try
    again", advice that can never work.
  - malformed asserted addresses are refused rather than trimmed into shape.
  - dead config (microsoftTenantId defaulted to 'common', which the provider code now
    refuses) and the orphaned google-auth-library dependency removed.

1591 tests pass. Domain lifecycle verified end to end against a running server.

ScreenTinker d26aaebef6 SSO: fix an account takeover, a remote crash, and login CSRF found in review
Five reviewers went at the two SSO commits. Three of them independently
demonstrated a full account takeover, and it was the same defect each time.

TAKEOVER. An org admin supplies the issuer and client_id, so they control that
identity provider completely and can mint an id_token asserting ANY email with
email_verified:true — including a platform_admin's. Every cryptographic check
passed honestly, because the attacker IS the issuer. upsertFederatedUser then
re-pointed the existing account at whichever provider spoke last, because the
only guard was `password_hash IS NULL` — and every SSO-created account has a
null password. Sessions were issued as the victim, and the victim's own login
then failed forever with subject_mismatch.

The rule came from the old Google handler, where it was safe: only the operator
could add a provider. Making providers customer-configurable turned it into a
takeover primitive and the assumption was not re-examined. Now an org provider
may only assert emails inside the domains it registered, and may never adopt an
account another provider established.

REMOTE CRASH, unauthenticated. The state comparison guarded on UTF-16 character
length while Buffer.from produces UTF-8 bytes, so a state of 43 characters
containing one multi-byte character reached timingSafeEqual with mismatched
buffers and threw — inside an async handler, which Express does not catch, which
server.js turns into process.exit. One request per restart killed any instance
with SSO enabled. Compared as bytes now, and /api/auth/oidc gained a rate limit.

LOGIN CSRF. The callback returned the session token in the URL fragment, so a
crafted link installed an ATTACKER'S token and silently signed the victim into
their account. The token now goes in a one-shot httpOnly cookie exchanged at
POST /sso/claim, which a link cannot forge.

FRONTEND, dead on arrival twice over. login.js used `await` in a non-async
function — a SyntaxError that takes the WHOLE app down, since app.js imports it
statically and there is no bundler. And `esc` was never imported, so the org-SSO
button could never render; the ReferenceError was swallowed by the catch written
for network failures. Both slipped through because `node --check` parses these
files as CommonJS and exits 0 on a broken module. The correct check is
`node --input-type=module --check`, and all four frontend files now pass it.

PUBLIC EMAIL DOMAINS cannot be claimed. A tenant had claimed gmail.com in
review, after which every Gmail user typing their address was offered "sign in
with your organization" pointing at that tenant's infrastructure — phishing from
this product's own login page. server/lib/public-email-domains.js.

MICROSOFT multi-tenant is refused rather than silently broken. `common` metadata
advertises the literal template {tenantid}, so the issuer never matches and
every login already failed; and loosening that check is nOAuth. A tenant GUID is
now required, with a loud warning at boot.

SSRF: https only, loopback/RFC1918/link-local refused, redirects not followed,
and the test endpoint no longer echoes upstream status for a caller-supplied
jwks_uri (it was a readable internal port scanner).

Also: an omitted email_verified was accepted (the comment already said it should
not be); the domain-uniqueness check raced an 8s network call before its insert
and is now inside the transaction; same-org duplicate domains were allowed and
made routing depend on table-scan order; routing is now ordered; a client secret
that cannot be decrypted fails closed instead of silently downgrading to a public
client; SSO audit rows were writing the org id into the deviceId column; and
/sso/start was capped at 10/min per IP, which would 429 the 11th employee behind
a corporate NAT.

Adds per-provider editing in the org admin UI (replace-only secrets — never
returned, blank means keep, explicit clear) and a Test button that checks
discovery, endpoints and signing keys while stating plainly that it cannot
verify the client ID, the secret, or the redirect URI registration.

⚠️ STILL MISSING: domain-ownership verification. A claimed domain means "nobody
else had claimed it", not "they own it". DNS TXT proof is the remaining control.

1582 tests pass. New regression tests cover the takeover confinement, ordering,
fail-closed secrets, the Microsoft refusal and the public-domain blocklist.

ScreenTinker e97228a502 SSO: per-organization providers, configured by the customer
Instance-wide providers belong to whoever runs the server. These belong to a
CUSTOMER: an organization points ScreenTinker at its own identity provider from
Settings → Single sign-on, with no environment variable and no restart.

The login flow is unchanged. An org provider is resolved through the same
oidc-providers.get(slug) the env ones go through, so there is one authorization
request builder, one token exchange and one verifier — not a second, less
tested path for tenants. That seam is why Phase 1 put provider lookup behind a
single function.

⚠️ An org provider is NEVER published. It is not in /api/auth/providers, because
listing a customer's IdP would both offer it to people it does not belong to and
leak the customer list from the login page. It surfaces only when someone types
an address at one of that organization's domains; otherwise the instance-wide
buttons are what you get.

The discovery endpoint answers with a BOOLEAN and nothing else — no slug, no
display name. Returning "yes, Acme Corp SSO" would turn a guessed domain into
confirmation that Acme buys this product, and the slug would hand out a working
entry point to their tenant. POST /sso/start repeats the lookup server-side and
redirects, so the browser never learns which provider it is being sent to until
the provider says so, and the address travels in a body rather than in a URL
that lands in history, proxy logs and a Referer. Both endpoints rate limited to
10/min.

Other properties, each with a test:
  - slugs are RANDOM, not chosen, so two customers cannot collide on or guess
    each other's URL
  - a domain may be claimed by ONE organization; a second claim is refused, so a
    tenant cannot capture another company's logins
  - the issuer is verified by live discovery BEFORE the row is written, so a
    typo is caught at configuration rather than by a user staring at a failed
    login
  - client secrets are optional (PKCE), stored AES-256-GCM via lib/secretbox,
    never returned; an absent secret on update leaves the stored one alone,
    which is how a settings form that cannot show it avoids blanking it
  - cross-org access answers 404, not 403, so an outsider cannot confirm that an
    organization id exists
  - signing in through an org provider grants membership of that organization,
    but never changes an existing member's role

Verified live end to end: creation against a real issuer, domain normalisation
(`@Acme.CO.UK` → `acme.co.uk`), boolean-only discovery, a rejected domain
squat, a rejected bad issuer, and 404 for a foreign organization.

ScreenTinker 252854d31e SSO: one OIDC flow for every provider, and verify the token properly
The OAuth support that was here could not work and would not have been safe if
it had.

It could not work: the login page called google.accounts.oauth2 and
new msal.PublicClientApplication, and NEITHER SDK WAS EVER LOADED by any page
in this app — no script tag, no dynamic import, nothing. Both buttons threw
ReferenceError on click. Even had they loaded, the CSP allows scripts only from
'self' and cloudflareinsights, and frames only from self and YouTube, so the
libraries and their popups were blocked too.

It would not have been safe: both endpoints authenticated with an ACCESS token
and neither checked who it was issued for. POST /auth/google fell back to
tokeninfo?access_token= and read the email out of the reply; POST
/auth/microsoft handed the bearer token to Graph /me and trusted that. Graph
and tokeninfo will both describe the user behind a token minted for SOMEBODY
ELSE'S application, so any site a user signed into that requested `email` or
`User.Read` could have replayed their token here and been issued a session as
them. Both endpoints are deleted; nothing is lost, because nothing could reach
them.

Replaced by ONE generic flow — Authorization Code + PKCE (S256), run
server-side, with the provider list resolved through a single function so
per-organization SSO can extend it later without a second login path. Google
and Microsoft become ordinary configured providers; Okta, Keycloak, Authentik,
Auth0 and anything else that speaks OIDC now work with three env vars.

Because the exchange happens server-side the browser never talks to the
provider, so there is no SDK to load, no client id in the page, and no
third-party origin needed in the CSP.

Identity comes from an ID token that must survive: signature against the
provider's JWKS (asymmetric algorithms only — alg:none and HMAC are refused
outright, the latter because the only key we hold is public), `iss` exactly as
discovered, `aud` and `azp` matching our client, `exp`, and a `nonce` this
server minted for that login. State is compared in constant time against a
value in an httpOnly SameSite=Lax cookie, so the callback is CSRF-protected and
survives a restart mid-login.

Account rules are the ones already in place: a verified email is required, an
SSO login never takes over an account that has a password, and a changed `sub`
for a known address is refused rather than handing the account to a recycled
mailbox.

18 new tests, every one describing something the old code would have accepted:
cross-audience tokens, azp mismatch, replayed nonces, alg:none, HMAC forgery,
wrong signing key, expired tokens, a discovery document lying about its issuer,
and a registry that never leaks a client id or secret to the browser.

Verified end to end against Google's real discovery document: the redirect
carries response_type=code, PKCE S256, state and nonce, and every callback
guard rejects as intended (no cookie, wrong state, no code, provider refusal,
unknown provider).

⚠️ TOTP is still not prompted on an SSO login, matching the documented
behaviour of the previous SSO and API-token paths. That is a product decision
and is left unchanged here rather than altered silently.

ScreenTinker 1ec32197b2 Let a BrightSign host COLLECT its capture request over HTTP
Server side of the inverted capture path. The host half is not here — see the
end of this message.

Every other player is TOLD to capture: the server emits device:screenshot-request
over the device socket and the page photographs itself. A BrightSign cannot
photograph itself. Video decodes onto a hardware plane the DOM cannot read, so
an in-page canvas returns a frame with the content missing — which is why that
platform has been answering screenshot requests with a card explaining that the
video is uncapturable. Only the host, through the player's own DWS, can get a
real frame.

The obvious way to ask the host is through the page, and it does not work. On an
XT245 (BOS 9.1.93.2) page->host messaging is dead after load: instrumenting the
host to echo the `reason` of EVERY roHtmlWidgetEvent produced nothing at all
while the page was posting, though the boot-time probe round-trips. The registry
is not an alternative either — a running BrightScript does not observe registry
writes made by anyone else, proven by writing the key externally through the DWS
and watching the host ignore it.

What the host CAN do is HTTP; it already fetches its own package updates that
way. So the direction is inverted: the request waits here and the host collects
it. The image comes back over a plain POST, which means a capture will work even
when the page is wedged — exactly when an operator most wants to see the screen.

Held in memory on purpose. A capture request is worthless a minute after it was
made — someone clicked a button and is watching for the result — so persisting
it would only add a way to deliver a stale screenshot after a restart. Bounded
and TTL'd so a fleet going offline mid-request cannot grow it, and a repeat
request REPLACES rather than queues so a 1fps stream builds no backlog.

Authenticated with the same device_id + device_token pair the socket uses.
/api/brightsign/package is public because a player fetches it before it has any
identity; a screenshot is a picture of a customer's screen and belongs to one
display.

deviceSocket now exposes ONE ingestScreenshot() used by both the socket handler
and the HTTP route, so a BrightSign screenshot reaches the dashboard by exactly
the route every other player's does rather than becoming a second, subtly
different feature. Note those exports must be attached AFTER
`module.exports = function setupDeviceSocket`, which reassigns the object —
attaching above it silently wipes them, which cost a debugging round.

NOT INCLUDED, deliberately: the host-side poll. Adding it to autorun.brs's main
loop kills the BrightScript script within seconds of boot — the page keeps
playing, because the widget outlives the script, so from the dashboard it looks
healthy. Cause unidentified; BrightScript runtime faults do not reach
/api/v1/logs, so there is no error text to read. Half a feature that silently
takes down the host is worse than none, so the server waits for a host that can
safely ask.

ScreenTinker 95b8d1b293 Export shared modules to the browser even when Node is in the page
Transitions have never run on BrightSign, and it was never a GPU problem.

`transitionRuntimeReady()` is a presence check on three globals and touches no
WebGL at all. A BrightSign roHtmlWidget is created with `nodejs_enabled: true`,
which puts Node's `module` into classic-script scope — so every shared module
that exported with an `else` took the CommonJS branch and never assigned its
browser global. The runtime was absent before WebGL was ever asked a question.

This is deducible from the fleet without touching the hardware: the player
pushes system.reboot / display.power / display.resolution / system.self_update
only behind BS.hasHost(), which needs require('@brightsign/messageport') to
resolve. Our XT245's stored capability row carries all four, so Node
integration was live in that page, so the CommonJS branch was taken.

Transitions are the least of it. schedule-eval.js had the same shape, and the
player falls back to "always active" when ScheduleEval is missing — so per-item
DAYPARTING silently stopped applying on that platform and scheduled content
played outside its window with nothing in any log. player-media-health.js the
same. Four files, all fixed by exporting to BOTH targets rather than either/or.

media-mute.js, orientation-style.js and wall-geometry.js already assigned their
globals in a separate unconditional block and were never affected; the audit
that reached me claimed all seven, and reading them is what separated the four
from the three.

THE GUARD, WITHOUT WHICH THE ABOVE IS A REGRESSION.

Restore the globals alone and BrightSign starts attempting video wipes it
cannot supply. On a hardware video plane drawImage(video) succeeds, throws
nothing, and paints a fully TRANSPARENT frame — so the wipe fades from nothing,
behind a video plane that is still lit. Worse than the hard cut it replaces.

The discriminator already existed: videoFrameIsCapturable() probes ALPHA, so a
genuine fade-to-black still reads as captured. It was wired into the screenshot
path and not this one, which asked isMediaReadable() — a CORS question, "am I
allowed to read this", not "did any pixels arrive". Both the outgoing frame and
the incoming warm-play snapshot now consult it, cached per platform, defaulting
to available while undetermined so a cold start is not crippled.

Net effect on BrightSign: image-to-image transitions light up, anything
involving video hard-cuts honestly, and dayparting starts working.

Full video transitions are reachable later — BrightSign documents that video
"captured as a canvas for WebGL processing must be routed to the GPU" via a
per-element hwz="off", which keeps hardware decode at an 8-bit/1080p ceiling.
That needs the hardware to validate and is not in this change.

ScreenTinker 5b069b9665 Probe video asynchronously — the sweep would have blocked the loop per file
The backfill is right, and it lands on a path that could not carry it yet.

deriveMediaMetadata spawned ffprobe and ffmpeg with execFileSync, each with a
15s timeout. Synchronously, those two calls stop the whole server for their
duration: no heartbeats, no socket traffic, no HTTP. That was survivable while
the only caller was a human-initiated upload — one file, someone waiting on it,
bounded by their patience.

The boot-time sweep removes every one of those mitigations. It walks the entire
library, unattended, on a server with live panels, once per boot. A library of
video rows therefore becomes a per-file event-loop stall, which is #240's
failure mode — blocked loop, missed heartbeats, panels marked offline,
reconnect churn — arriving from our own maintenance instead of from a
checkpoint. We spent yesterday removing one of those; this would have added
another, on a schedule.

So both spawns are awaited instead of blocked on. Both callers already awaited
deriveMediaMetadata, so this is invisible to them, and the ingest path stops
freezing the server for the length of an upload's probe as a side benefit —
that sync ffprobe has been known tech debt for a while.

Timeouts are unchanged and still asserted: async is not a licence to hang, or
one wedged file stops the sweep dead instead of moving on.

Also applied the PR's own phantom-path discipline to the video branch, which
still named its thumbnail before the encode: a failed ffmpeg left the row
claiming a file that was never written, which is the exact bug the image branch
was fixed for two commits earlier.

The new test measures the property rather than grepping for it — a timer keeps
ticking across a real spawn — so a future edit that reintroduces a sync call
fails here rather than in a customer's fleet.

Rob K bfe8a4c907 Backfill missing thumbnails at boot, and say when ffmpeg is absent
Ingest-time thumbnail generation is best-effort by contract, so a row that
misses it stays bare forever: video uploads on a host without ffmpeg (a
SYSTEM dependency nothing surfaced), or content from before thumbnails
existed. Operators read that as "thumbnails don't work".

Two additions. A [MEDIA] startup diagnostic (async probe, cached) states
loudly whether ffmpeg/ffprobe were found, mirroring the [EMAIL] block. And
a once-per-boot sweep re-derives metadata for local image/video rows with
no thumbnail — serial, paced, delayed past boot, unref'd. The sweep's row
UPDATE re-checks that thumbnail_path is still empty so it never clobbers a
thumbnail written concurrently by the replace flow, removes its just-written
file when the row vanished mid-derive, salvages probed dims/duration even
when the thumbnail itself failed, and stops after 25 failures per boot so a
library of undecodable clips can't turn every restart into subprocess churn.

Rob K 3f1c044940 Return no thumbnailPath when the image thumbnail write fails
deriveMediaMetadata assigned thumbnailPath before sharp wrote the file, so
a failed write (corrupt image, disk error) returned a name for a file that
was never created. Ingest then stored that phantom thumbnail_path and the
dashboard requested it forever as a broken image. Assign only after the
write succeeds; the video branch already nulled its path on failure.

ScreenTinker 5fa6b2d07d A baseline moves when the fix reaches SCREENS, which is not one rule
Two changes that are really one idea: the parity model treated all four
players as if they update the same way, and they do not.

WEB AND BRIGHTSIGN GET audio.volume BACK.

The audit removed it because v1.9.28's index.html contained the string
set_volume zero times, and because the handler read payload.value while the
dashboard sends { level }. The second reason 1.9.31 fixed. The first was
reasoning from the wrong artifact: this player is SERVED BY THE SERVER, so a
browser panel runs whatever build is answering it, not the release its row was
created under. There is no browser panel stuck on the v1.9.28 player once the
server moves — and prod moved tonight. The slider works on those displays right
now while the baseline says it does not, so the dashboard is hiding a working
control from every display that declares nothing.

BrightSign comes with it, on the same served player. The unit-specific doubt is
whether a hwz player's media element is reachable at all — and that is already
answered by audio.mute, which this baseline has always claimed: set_volume
reaches setMediaVolume() and device:mute-changed reaches currentVideoEl.muted,
same element, same path. If hwz swallowed one it would swallow both.

TIZEN DOES NOT COME WITH THEM, AND THE TEST NOW KNOWS WHY.

A .wgt sits on the panel until somebody updates it. Cutting 1.9.31 put nothing
on any screen, so an un-updated Tizen panel still has the broken handler and
moving its baseline would resurrect the dead slider on real hardware.

The test could not express that. It judged every family against "shipped
source", resolved as the newest tag — which is HEAD on a release commit, so
tagging 1.9.31 flipped all four biconditionals at once and demanded a baseline
change for displays that cannot have the fix yet. Green tree, red build, naming
a baseline, with nothing in the diff to explain it. main would have gone red on
the next commit whatever it contained; #242 just got there first.

So the two families are now modelled separately. Server-served: judged against
the working tree, both directions, because both are decidable from the build we
are about to serve. Device artifact: judged against the previous release, and
only in the over-claim direction — "the baseline claims it, so the shipped
player had better implement it" is always true and worth failing on, while
"HEAD gained the handler, so add it" is a guess about how many panels have
updated. The cost is that a stale entry can outlive the artifact reaching the
fleet; that is a judgement about screens, so a person makes it in
player-capabilities.js and records why.

player-capabilities.test.js carried the same stale reasoning hardcoded, and
docs/player-parity.md stated the old facts in four places — a parity matrix
that lies being the exact failure this whole model exists to stop.

screen_off blanks a fielded panel for real (owner/admin FORCE_LOCK, else the
accessibility lock); screen_on is a logged no-op. One capability renders both
dashboard buttons, so withholding the pair to hide the dead ON button also takes
blank-at-night — the half that gets scheduled — away from every panel that has
not updated. Panels that have updated declare for themselves.

ScreenTinker 3e37d33b80 QA: close four ways a control or an asset lied about itself
Found by driving the real server and a real browser, not by reading. Each fix has a
test that fails without it.

1. A missing upload answered 200 with the DASHBOARD. express.static falls through on a
   miss and the SPA catch-all caught it, so GET /uploads/content/<gone>.mp4 returned
   15KB of index.html as text/html — under the `immutable, max-age=30d` header the mount
   sets before it knows the file exists. Every player downloader treats 200 as success,
   so a panel stores the HTML page AS the video and caches it for a month, rendering a
   black frame with nothing in any log. Reachable exactly when it hurts: a content
   replace writes a new random filename and unlinks the old one. The mount now
   terminates a miss with a 404 and drops the cache header.

2. Four dashboard->device socket handlers had no capability gate. dashboard:device-command
   has always refused a command the panel cannot honour, and the comment above it is right
   about why ("hiding the button is not enforcement — this socket is reachable directly").
   Every word applied to the four handlers immediately above it, which had none: a display
   declaring [] still received screenshot-request, remote-touch, remote-key and
   remote-start. Measured, not inferred. They now refuse on remote.screenshot /
   remote.input / remote.stream and name the capability in the ack; remote-stop stays
   ungated for the same reason set_debug does. The undeclared fleet is unaffected — an
   absent declaration still resolves to its platform baseline and keeps everything.

   The wall panel list (#235) made this visible: it offered a Screenshot button for every
   panel, including a BrightSign, which has no screenshot capability at all, and popped a
   toast promising an image that was never coming. GET /api/devices now ships the RESOLVED
   capability array rather than the raw column ('[]' as a STRING, which Array.isArray reads
   as "pre-capability server, show everything" — wrong in the one case that matters), so
   the wall list and the fleet cards can hide what a panel cannot do. The remote pad's
   Scrn Off / Scrn On were gated on remote.input while the Info tab gated the same two
   commands on display.power; both now agree.

3. A register with no `platform` ERASED the stored one. captureIdentity coerces a missing
   field to the literal 'unknown' and persistIdentity wrote it straight over. That column
   is load-bearing: platformFamily() reads it, so one reconnect from an older build turned
   a Tizen panel into a browser tab and handed it a volume slider the .wgt has no handler
   for — the exact control BASELINE.tizen exists to hide — while a BrightSign lost screen
   power and reboot and gained screenshots it cannot take. platform and client_type are
   now preserved (physical facts); client_version and contract_version still decay, because
   there "we no longer know" is the truthful answer. client_type 'wgt' is also read as a
   second signal for a Tizen TV.

4. PUT /api/content/:id/replace carried its own shorter copy of the ingest logic. Replacing
   a video left duration_sec at the OLD clip's length and nulled width/height, so #237's
   brand-new "default an item to the clip's own length" then handed out the wrong number
   for every later add — 32s scheduled for a 5s video is 27s of frozen frame. Replacing an
   image measured it with raw sharp metadata and thumbnailed without .rotate(),
   re-introducing the EXIF-orientation bug #172 had just fixed at ingest. Both paths now
   share lib/content-ingest.deriveMediaMetadata.

Verified working and NOT changed: all six item-duration insert paths (a 31.7s clip stores
32 everywhere, an explicit value always wins, and no path can store a 0); the content
revision bump + filepath refresh reaching a real device socket; a landscape wall producing
byte-identical geometry to the pre-#236 expression; a portrait wall reaching the player as
side-by-side halves; cross-workspace isolation across 29 probes.

Full suite green (1319).

ScreenTinker 4e1de8ec0e Make the Tizen and BrightSign players do what they say they do
Both players carried calls that compile, read correctly, and are documented to
do something else. Verified line by line against docs.brightsign.biz and
Samsung's Smart TV Filesystem reference; every fix below cites the doc that
proves it, and the linter has been extended so each one fails here next time.

TIZEN

The offline media cache could never have worked on a panel. Its adapter used
the deprecated Filesystem API in three ways the IDL rules out:
`tizen.filesystem.resolve()` is declared `void`, so `var dir = resolve(...)`
was always undefined and MediaCache.create() returned null on every panel in
the fleet; `openStream()` is asynchronous, so appendPart read `written` before
any callback could run and returned 0 forever; and `moveTo()` is asynchronous,
belongs on the parent directory, and takes (origin, destination) — it was
called on a file handle with the arguments transposed. Rewritten against the
5.0 synchronous FileSystemManager, which is genuinely synchronous and is what
the decision layer needs. A Tizen 4.0 panel now reports available() false
instead of being handed a cache that silently writes nothing.

Writes are now POSITIONED rather than appended at EOF. Power cut between a
write and the index save — the exact event this feature exists for — replayed
the last chunk, and an append landed it twice: a silently corrupt video that
promoted as complete. A positioned write makes the replay idempotent.

Three decision-layer bugs alongside it: a 206 with no readable Content-Range
fell back to Content-Length, which is the CHUNK length, so the first megabyte
of a 50MB video promoted as a complete 1MB asset; a 200 whose body was short of
its own Content-Length returned 'done'; and a server with no ETag or
Last-Modified was re-fetched from zero on every sweep, forever, on precisely
the marginal link this feature exists to be gentle on.

The volume slider was dead. The dashboard sends `{level: 0..1}`; this handler
read `value`/`volume` as a 0..100 percentage, so it matched nothing and logged
"no usable value in payload" on every slider move while the panel declared
audio.volume as working. Both halves had to move together — taking `level` as a
percentage turns 50% into 0.5%, which is inaudible and looks like a fix.
Verified by driving the real handler in headless Chrome, before and after.

BRIGHTSIGN

FindMemberFunction is documented as available only when
roDeviceInfo.HasFeature("FindMemberFunction") is true. It was called
unguarded from the capability probe and from host telemetry — both on the event
loop — so a player without the feature would have died within a minute of boot
and taken the display with it. The guard needed guarding.

The boot report never arrived. The host flushed its buffer straight after
Show(), before the page had been fetched, while the player correctly waits for
its socket before subscribing. Between two correct decisions every boot line
fell on the floor. The host now waits for the page's `probe`, and the bridge
buffers until a consumer registers.

offline.cache was claimed on `navigator.serviceWorker` being present. It is
present on a BrightSign widget and will not run a worker — our XT245 passes the
check and never fetches sw.js. Now requires a controller, matching the web
player. Removed from the brightsign baseline for the same reason.

display.resolution was claimed on @brightsign/videooutput, which has no
setMode at all; mode setting lives on @brightsign/videomodeconfiguration.

roStorageHotplug.GetStorages() answers "USB1:/" while GetStorageStatus() is
documented as unreliable for "USBn:" — feeding one to the other re-created the
bug the static fallback list exists to avoid, and only on the OS versions that
have the enumerator.

dual/clone output mode put two full-screen widgets on output ONE, on top of
each other, while output two stayed dark: roHtmlWidget has no output selector,
and a second output is addressed by its display_x/display_y within the
SetScreenModes canvas. Now positioned properly, or refused with a reason.

Also: a manifest missing sha256/size passed `invalid` into typed parameters, a
runtime error at the call the comment already described and did not prevent;
storage_quota was a string where the docs say use a double; and the comment
crediting brightsign_js_objects_enabled with gating require("@brightsign/*")
named the wrong flag — it is nodejs_enabled.

TESTS

The two suites that mattered most were the ones that passed while the code was
broken, because they asserted on source text or against a fake more correct
than the platform. The host-diagnostics regexes now execute the bridge; the
media-cache suite now drives the shipped adapter against a fake tizen.filesystem
written from Samsung's IDL. Ten new rules in the BrightScript linter, each
verified to fail against the source it was written to reject.

ScreenTinker c1270599c3 Make the parity matrix true, and stop three controls that do nothing
The parity doc and the capability model had drifted from the players in both
directions, and nothing failed when they did. Auditing all four players against
their shipped sources turned up three controls a customer can press today that
change nothing, and a set of baselines that were partly too generous and partly
too stingy.

The three dead controls:

  - The volume slider works on Android only. The dashboard sends set_volume as
    { level: 0..1 }; the web player reads payload.value and Tizen reads
    payload.value ?? payload.volume, so on both the number is undefined and the
    handler quietly declines. Three complete, working volume implementations
    that cannot be driven. The fix is one line in each player and belongs to
    those files; audio.volume is out of the web and brightsign baselines until
    it lands, held there by a biconditional test that fails the moment a player
    starts reading `level`.

  - Every #161 Tier-2 command was refused for the entire fleet. lock_now,
    power_menu, status_bar, block_uninstall and unblock_uninstall were gated on
    system.device_owner, which no player declares and no baseline grants, so
    supports() was false everywhere -- including on the device-owner panels the
    feature was built for. The dashboard still drew the buttons because it also
    gates on device.tier === 2. Fixed here: those five now accept
    system.device_owner OR system.kiosk, which PlayerCapabilities.kt declares
    under `if (isOwner)` and nothing else, and which no non-Android player
    declares. Android should declare system.device_owner and retire the
    stand-in.

  - enable_system_capture required the capability it creates. It raises the
    MediaProjection consent dialog -- the way a panel GAINS capture -- and was
    gated on remote.screenshot, so the only panel that needs it was the one
    panel that could not be sent it. Now ungated. The dashboard still hides the
    button behind the same check; that half is a frontend change.

The baselines describe what an un-updated fielded display can do, and since
v1.9.29 is the first build in which any player declares anything, that means
v1.9.28. Every entry is now justified against `git show v1.9.28:<source>`:

  - android loses display.power (v1.9.28 answers screen_on with a logged no-op,
    so the ON half is dead on every fielded panel and one capability renders
    both buttons) and system.reboot (owner-only; off-owner it paints an
    accessibility power dialog over the signage). Scheduled reboots now skip
    undeclared Android panels rather than logging a reboot that never happened,
    which is the reason that gate exists.
  - tizen gains display.power: v1.9.28 implements both halves with no signing
    and no panel API, so withholding it hid a working control.
  - brightsign loses audio.volume, display.power, system.reboot,
    system.restart_player and offline.cache. All need a host bridge the unit is
    not known to have, and restart_player without one is the page reload that
    darkened a panel on 2026-07-28.

Also found, not fixed here because the files belong to others:
st-bridge.js computeCapabilities() is dead code -- nothing calls BS.capabilities()
-- and its 199 lines of passing tests constrain nothing a BrightSign actually
declares; the two disagree on six capabilities and the bridge is right about
most of them. BrightSign's "Force update" button is dead. PlayerCapabilities.kt
under-declares display.brightness.

The new test reads the player sources rather than the table: a dead-button rule
(every gated command has a branch somewhere), an unreachable-capability rule
(which would have caught system.device_owner), and biconditionals so a fix in a
player fails the test until the baseline follows. Claims that need hardware --
CEC reaching a display, a widget being allowed a service worker, SyncManager
holding frame lock -- are marked unverifiable in the document instead of
asserted.

ScreenTinker 97f53a5b72 Merge #238: preview a rotated display the way the wall shows it 2026-08-06 09:50:27 -05:00
Claude e4c25c39df Describe a portrait video wall as portrait, and stop a wall hiding its screens
#236: the wall canvas was secretly framebuffer space rather than the wall as
the audience sees it. Invisible while every panel is the normal way up, and
actively misleading the moment one isn't — two portrait-mounted panels standing
side by side had to be STACKED VERTICALLY in the editor, with a pre-rotated copy
of every video, before the output came out right. It worked, but only after
trial and error, and it meant a portrait wall could never reuse content as-is.

Each panel now carries a mounting rotation (0/90/180/270 clockwise, the same
convention as the per-device orientation setting), the canvas means the physical
wall, and the player works out the mapping. The geometry lives in one place,
server/lib/wall-geometry.js, because four players have to agree on it to the
pixel across a seam.

Existing walls need no migration and do not move. Every wall in the field is
rotation 0, and that case takes the original expression verbatim on all three
players rather than the algebraically-equal centre-based one — the two differ in
the last float bit, and a float's worth of disagreement between two panels is a
hairline seam down a wall that was aligned yesterday. Pinned by the first test
in wall-geometry.test.js and by wall-payload.test.js.

While a display is in a wall its panel rotation replaces its own orientation:
both describe the same physical fact, so honouring both turned the content twice.

#235: a wall replaced its members' cards, so one dead panel of a four-panel wall
was invisible from the dashboard, and inspecting a single screen meant pulling it
out of the live wall and putting it back. The wall screen now lists its panels
with live online state, a per-panel screenshot request, and a link to each
device's page; the dashboard wall card carries per-member status chips that track
socket updates.

Tests: wall-geometry.test.js re-simulates the CSS box independently and asserts
each panel's viewport maps onto exactly its own rect of wall space, for every
rotation, plus a mixed wall and the Tizen player's hand-ported copy executed
against the canonical rule. Full server suite green (1260).

Not verified here: the Android and Tizen renders on real hardware. Kotlin
compiles clean; the maths is shared/tested, the view plumbing is not.
2026-08-06 09:46:31 -05:00
ScreenTinker 52ab04204a Preview a rotated display the way people see it, not the way its framebuffer is
#238: the dashboard preview of a 90/270 display was sideways while the panel on the
wall was right — the split that makes a preview useless, because a designer checking
portrait content can no longer tell a real fault from an artefact of the tool.

A portrait panel is a landscape framebuffer that the player rotates content INSIDE
(+90), hung turned the other way (-90); the two cancel and the viewer sees upright
portrait. The dashboard modelled only the first half. It iframed the player into a
box it had already given the finished 9/16 shape, so the player rotated a second time
inside a box that was pretending to be the finished picture, and nothing anywhere
stood in for the mount. Screenshots had the opposite half missing: they are the raw
framebuffer, shown untouched, so every portrait screen looked wrong on the cards and
in Now Playing too.

So each surface now has a stage (the panel's face) and a frame (its framebuffer),
with the frame turned by the INVERSE of the player's angle. Turning it the same way
is the tempting mistake and the worst kind of wrong: 90+90 lands upside-down, which
reads as nearly-right. The dimension swap is not cosmetic either — composing into the
real framebuffer shape is what makes the player lay content out in the same portrait
box the panel uses; hand it a portrait viewport instead and every zone and object-fit
decision is computed for a canvas no panel has.

The geometry is the players' own rule (server/lib/orientation-style.js), served to the
dashboard rather than re-derived, since a second copy of a rotation rule is exactly how
the two came to disagree. Covers the device preview modal, the playlist preview's
portrait toggle (same fault), Now Playing and the device cards. The Remote canvas stays
raw on purpose: taps are sent as fractions of it.

ScreenTinker 6471c503ab Default a video playlist item to the clip's own length (#237)
Adding a 32s video gave it the flat 10s default, so it was cut off mid-play
unless the operator looked up the runtime and typed it — per item, every time.
The content row already carries the probed duration; it now becomes the default.

The rule lives in one place (lib/item-duration.js) because the operator sees one
product, not six insert paths: playlist add, assign-to-display, group assign,
agency portal, content-only schedule, and the public API all share it. Only the
playlist route defaulted before, and it stored the raw probe (31.7) which the
Android player's optInt read silently truncated back to 31.

Explicit values always win. Content with no trustworthy duration (image, widget,
YouTube, remote URL, failed probe) keeps the 10s default, and a duration that is
0/negative/NaN or absurd (> 12h, i.e. a broken probe) falls back rather than
reaching a device — a 0 makes the players schedule a 0ms advance, which self-loops
and black-screens the TV.

Dashboard: the add-item picker shows a clip's length, the assign-to-display modal
pre-fills the duration field from the selected clip (never overwriting a value the
operator typed), and onboarding stops hardcoding 10 on the first assignment.

ScreenTinker 684e60fc55 Offline media on every player, and a revision so the cache can still be updated
Two halves of the same problem. A screen has to keep playing when the link is
gone, and it must not keep playing the wrong thing once the link is back.

CACHING FOR OFFLINE, on the players that could not:

- Tizen cached nothing but the playlist, so a panel came back from a reboot
  knowing exactly what to show and fetched every frame of it from a server that
  was not there. tizen/js/media-cache.js caches the media itself to wgt-private
  (the store Tizen documents as surviving reboots), resumable via Range and
  If-Range, with the transfer async so a stalled chunk cannot freeze the player.
  offline.cache moves from "absent" to a runtime claim: a build with no writable
  private storage still says nothing.

- The web player's worker stored only what a single fetch() happened to
  complete, which on a marginal link is nothing at all — a 200MB asset never
  finishes in one go and every retry starts from zero. It now accumulates in
  resumable chunks, driven by the player's playlist rather than by playback, so
  the prefetch is not competing with the video that is currently on screen for
  the same scarce bandwidth. BrightSign inherits this.

STILL UPDATING, which caching quietly breaks:

PUT /api/content/:id/replace changes an asset's bytes under a stable id. Every
cache keys on that id, so before this the new bytes could not reach a panel that
already held the old ones — not until the next refresh, but never. Content now
carries a revision, stamped onto each item at send time like widget revs, and
every player keys its cache on it. The same send-time refresh fixes a second
bug: a replace writes a new randomly-named file and unlinks the old one, so the
filepath in a published snapshot pointed at a deleted file and web panels 404'd
on the item until somebody republished the playlist. The route now also pushes
to affected devices, which it never did.

Bytes are kept only where they can be built upon: no validator means no safe
resume, so the partial is discarded and the attempt backs off as the failure it
is rather than re-fetching the same prefix forever.

Server needed no new transfer support — res.sendFile already does Range,
If-Range and 416. The Tizen cache and the service worker are both driven in Node
against fakes, because neither can be exercised without hardware and "the chunks
assemble correctly" is not something to discover from a panel showing a corrupt
video.

ScreenTinker 4153448c55 Merge: capability persistence, dashboard gating, server-side refusal 2026-08-05 14:29:09 -05:00
ScreenTinker 0082191f9b Show only the controls a display can actually honour
Every device control was offered to every display. A browser tab was shown
"Reboot device", a Tizen TV was shown screen power, a player with no
framebuffer read was shown a live view that stayed black. They all looked
like working buttons and did nothing — the "reports success and changes
nothing" shape that keeps costing people days.

Players now declare what they can do at registration, because only the
player knows at runtime: an Android panel gains real screenshots when
accessibility is switched on and loses Tier-2 when device owner is revoked.
The dashboard hides what is not supported rather than disabling it, and the
Info tab lists the capability set so a missing control is explainable.

The declaration is three-state and the middle state is load bearing: NULL
means "has never told us anything" and falls back to a per-platform
baseline, because several hundred displays in the field will not update
before this deploys and blanking their controls would be a far worse bug.
An empty array means "I genuinely can do nothing" and is honoured.

Hiding a button is not enforcement, so unsupported commands are also
refused server-side — the socket is reachable directly and a stale tab
still renders the old controls. Group sends report skipped devices
separately from sent ones; counting an unreachable member as "sent" is how
an operator walks away believing the whole group rebooted.

ScreenTinker e5583e529e The Tizen baseline describes a fielded panel, not the one we are shipping
Two more corrections from the cross-player audit, both mine.

audio.volume removed: a fielded Tizen panel has NO set_volume handler — the
command falls through to "unknown command" and the dashboard slider does
nothing. One of the platform branches adds a handler, and those panels will
declare the capability for themselves once they run it; the baseline exists to
describe an un-updated display, so it must not borrow credit from a build that
has not shipped.

remote.screenshot and remote.stream added: both really are implemented in the
shipped player (captureAndSend, startStreaming). Omitting them would have hidden
working controls on every legacy Tizen display the moment gating went live —
the opposite failure, and the more damaging one.

That asymmetry is the thing to hold on to: over-claiming shows a dead button,
under-claiming removes a working one, and only reading the shipped code tells
you which you are doing.

ScreenTinker a08e6c3e06 Tizen does not have offline caching — correct the baseline
The platform audit caught my own contract lying. I gave the Tizen baseline
offline.cache; Tizen caches only the playlist JSON (st_payload_cache, in
localStorage) and has no service worker and no media cache, so the bytes still
come from the network and an outage leaves a panel holding a playlist it cannot
play.

That is exactly the claim this model exists to prevent, made by the model itself,
and it would have applied to every legacy Tizen panel — the ones that declare
nothing and depend entirely on the baseline being honest.

ScreenTinker 6bc709d2f7 The capability contract: what each player can actually do
Foundation for platform-native parity. The dashboard offered every control to
every display — a browser tab cannot reboot its host, a Tizen TV has no
device-owner concept, a BrightSign has no per-window brightness — so those
buttons did nothing, silently, and read as bugs. "UI that reports success and
changes nothing" is a recurring shape here; this ends it by letting the frontend
hide what a display cannot do.

The player DECLARES its capabilities at registration rather than the server
inferring them from a table, because only the player knows at runtime: an Android
device gains real screenshots when accessibility is switched on and loses Tier-2
commands when it is not device owner.

The trap this had to avoid is the opposite failure. Several hundred displays are
in the field declaring nothing, and none will update before the next dashboard
deploy — treating absence as "supports nothing" would strip the UI for the entire
fleet at once. So an ABSENT declaration falls back to a per-platform baseline,
while an EMPTY one is honoured as a player genuinely saying it can do nothing.
Those two cases are trivial to conflate and the difference is a dark dashboard.

Baselines carry only what has always worked on that platform. Anything
conditional — screenshots needing accessibility, kiosk needing device owner,
native sync needing one L2 network — is omitted, so a legacy display shows those
controls only once it declares them. A control that appears late beats one that
lies now.

Capability names are stable strings because they are persisted per device and
sent over the wire; renaming one silently disables a control on every display
still reporting the old name. An unknown name from a NEWER player is dropped
rather than invalidating the whole declaration.

1094 pass.

ScreenTinker d205a49dfa The settings PIN can be rotated and set from the dashboard
It was generated once at pairing and never changed. On a fleet that makes it a
shared secret with no expiry: anyone who watches it typed once — an installer, a
contractor, someone filming a screen — keeps it for the life of the panel, and
the only way to take it back was to unpair and re-pair every affected display. A
customer asked whether it rotates, which was the right question.

POST /api/devices/:id/settings-pin takes { rotate: true } or { pin: "123456" },
and pushes the result to the panel over its socket immediately. The live push is
the part that matters: without it a new PIN would only take effect at the next
pairing, so an operator revoking a leaked PIN would believe access was closed
while the old one still opened the menu. The response reports whether the panel
actually took it, so an offline display is stated rather than assumed.

Validation is the security-relevant half and is pure and tested: six digits,
digits only, and a blocklist of the PINs people actually pick (repeats and
sequences) refused on explicit set and never produced by the generator. A PIN
that can be set to "0000" or left empty is a gate that is not there.

Generation uses crypto.randomInt rather than Math.random — this is a credential,
and a rotation requested BECAUSE a PIN leaked must not be predictable from
anything else. Leading zeros are padded, or roughly one PIN in ten would be five
digits and rejected by the on-device prompt.

Android applies it live via device:settings-pin instead of only at pairing. The
PIN is never written to a log on either side, and it stays out of device list
responses as before.

1084 pass; Android compiles.

ScreenTinker 604c390a55 Portrait on the web player was 420px off-screen — rotating a box does not move it
Reported as "rotation doesn't work correctly". It is a geometry bug, not a
rendering one, which is why it reads as mysterious.

#playerContainer is pinned `inset: 0`. Rotation set width:100vh, height:100vw and
rotate(90deg) — leaving the box in the TOP-LEFT corner and spinning it about its
own centre rather than the viewport's. On a 1920x1080 panel the content landed at
x -420..1500, y 420..1500 against a viewport of 0..1920, 0..1080: correctly
rotated, wrongly placed, cropped on two edges.

Tizen already did this correctly — top/left 50% plus translate(-50%,-50%) — and
Android does the equivalent with translationX/Y of (w-h)/2. The web player was
the odd one out, and BrightSign inherited it on top of its own hardware-plane
problem.

The rule now lives in server/lib/orientation-style.js, served to the player from
its single source, with the arithmetic pinned by tests that compute where the
rotated box actually lands on 16:9 and 5:4 panels. Three things those tests hold
that are easy to get wrong: the translate must come BEFORE the rotate (transforms
apply right-to-left, so reversing them rotates the correction too), 180 must NOT
swap dimensions (the box already fits; swapping letterboxes it), and landscape
must clear EVERY property the rotated state set (a half-reset leaves the
container stuck at 100vh wide, so rotation appears to persist after switching
back).

1074 pass.

ScreenTinker df3a2879fa Remote screenshots use the framebuffer, and an opted-in tester can move forward
Two things reviewed against the hardware.

REMOTE CAPTURE. An in-page canvas cannot read the hardware plane, so a
screenshot from a BrightSign is a composite with the video missing. The player
now asks the HOST, which uses the unit's own Diagnostic Web Server to capture the
real framebuffer, video included.

It has to run in BrightScript rather than the page for two reasons: the DWS is
http on localhost while the player is served over https, so the page would be
blocked as mixed content; and BrightScript is subject to neither CORS nor
mixed-content rules. Credentials are the documented default — user "admin",
password = the unit serial — which the host reads directly.

It requires PRIMARY STORAGE: the endpoint writes the full-size capture to disk
before returning a thumbnail, so a unit with no card or SSD answers "No primary
storage found." That message is passed through verbatim rather than swallowed,
and the canvas path still runs as a fallback, so a player with no disk keeps
producing the partial screenshot it can rather than nothing at all. Verified
against the real unit: the endpoint is reachable and blocked solely on storage.

THE STUCK TESTER. An opted-in player on 1.9.29-rc1 was told "holding prerelease
of the same core" when offered rc3 — so it would never move forward through
rc1 -> rc2 -> rc3, which is the opposite of what opting in is for, and would have
stopped our own XT245 ever receiving the next candidate.

The hold rule exists to stop a test build being dragged BACK to its release. It
now applies only when the advertised version IS that release: a newer prerelease
of the same core is offered normally, the release still cannot claw a tester
back, a newer core still lands, and a player that never opted in is still refused
a prerelease.

Also verified end to end on alpha: the advertised sha256 matches the served bytes
exactly, size matches, and every member of the package is stored.

1063 pass.

ScreenTinker 30a71c1319 autorun.zip must be STORED and opened with roBrightPackage
A BrightSign consultant ran our v1.9.29-rc2 autorun.zip through BSN.cloud's
automated deployment. The archive reached the player and then could not be
opened — reported as invalid. Two causes, both ours.

1. COMPRESSION. We built with default deflate. The player bootstrap extracts
   autozip.brs by itself before any script runs, and roBrightPackage supports a
   specific set of methods, of which "no compression" is the universally safe
   one. Both builders now store: scripts/build-autorun-zip.sh passes -0, and the
   server-side package builder used archiver level 9 — maximum deflate — so
   EVERY self-update package it produced would have failed the same way, silently
   and in the field.

2. THE UNPACK API. We used roUnzip; BrightSign's own tooling uses
   roBrightPackage. Converted in autozip.brs and in the self-update path.

This is the failure mode worth naming: a compressed package uploads, downloads
and deploys perfectly, then fails to open on the player. It reads as a broken
deployment rather than a broken zip, so it gets debugged everywhere except where
the bug is. Both builders now ASSERT the property rather than trusting the flag —
the build script walks `unzip -v` and refuses a compressed member, and a test
walks the local file headers of the server-built package checking method 0.
Verified by negative control: re-enabling compression fails the test.

Also adopted the shipped volume-discovery pattern in autozip.brs — probe
USB1:/SD:/SSD:/FLASH: for the archive instead of guessing two volumes. The unit
that drove this port boots from FLASH because its card interface is dead, and
extracting to a volume that does not exist fails silently.

1056 pass.

Reported by giyokun, who was right about both.

ScreenTinker cf1124d687 Mute reaches YouTube items — it never did, and failed opposite ways per player
Some checks are pending
CI / Unit tests (node --test) (push) Waiting to run
CI / OpenAPI spec lint (push) Waiting to run
CI / Android unit tests (Kotlin schedule evaluator vectors) (push) Waiting to run
CI / Boot smoke + version check (push) Waiting to run
Muting was implemented three times and agreed nowhere. A YouTube item is a
cross-origin iframe, so `el.muted` reaches nothing; only the IFrame API can
touch it. Both browser-family players got this wrong, in opposite directions:

  web    playerVars.mute was `userHasInteracted ? 0 : 1` — autoplay policy and
         NOTHING else. An item an operator muted in the admin console played
         WITH SOUND, a wall follower blared alongside its leader, and the
         real-time device:mute-changed toggle only ever touched `<video>`.
         onReady then unmuted unconditionally, and the click-to-unmute overlay
         appeared on deliberately-muted items and undid the operator's setting.

  tizen  the embed URL hardcoded `mute=1`, so YouTube there was PERMANENTLY
         silent: the per-item flag was never read and nothing could unmute it.
         device:mute-changed did nothing at all, because it dereferenced a
         <video> that is null for a YouTube item.

Android was already correct and is unchanged — it is the reference here.

The rule now lives once, in server/lib/media-mute.js, served to the web player
from its single source the same way schedule-eval.js is, and mirrored in Tizen
(which ships inside the .wgt and cannot import it). The ORDER is the substance:
a wall follower is always silent (one wall, one audio source) > autoplay policy,
which is a hard constraint rather than a preference because unmuted playback
without a gesture is refused outright and costs the VIDEO > a live operator
toggle, who is looking at the screen > the item's stored flag.

shouldOfferUnmute() exists so the prompt only appears when a gesture is the ONLY
thing in the way. Prompting on a muted item trains viewers to click a button
that undoes an operator's decision.

Tizen gains enablejsapi + a postMessage bridge so a live toggle flips the embed
without reloading it — reloading would restart the video from zero every time
someone touched the control.

11 new tests pinning each precedence step separately; 1055 pass.

ScreenTinker 4ed7954f84 Drop the user-agent fallback — it could never fire
isBrightSignDevice() fell back to device.user_agent to catch panels paired
before this port existed, which registered as "Chrome 120" with a BrightSign
user agent. `devices` has no user_agent column, so the field is always undefined
on a row read from the database. The branch was unreachable in production and
passed only in a test that fabricated the field — which is precisely how dead
code survives review.

Two agents flagged it independently while working on unrelated areas, and the
schema confirms it: zero matches for user_agent in the devices table.

Those pre-port panels are recognised the moment they re-register on a build
carrying the host, which every one of them gets on its next update. Identifying
them sooner would mean persisting the user agent, and a column added solely to
track a population that disappears on its own is not worth carrying.

The test now asserts the honest behaviour: a fabricated user_agent does NOT
create a match, and a group containing such a panel reads as mixed until it
re-registers.

ScreenTinker 8fd6eb75d5 BrightSign: cache content for offline, and let the package update itself
Two gaps that both end the same way — a panel nobody can fix without a van.

OFFLINE. Content bytes were never persistently cached. The service worker
skipped /uploads/content/ and leaned on the browser's HTTP cache, which is
reasonable on a desktop and is not a documented-persistent store here:
BrightSign guarantees survival across reboots for IndexedDB, localStorage and
SQLite, and their own answer for offline video is to cache the bytes explicitly.
A panel could come back from a power cut with its playlist intact — that lives in
localStorage — and no media to play it with.

The reason content was skipped is real, and player-cache-policy.js is what makes
intercepting it safe. Seeking video issues range requests, and naive caching is
worse than none: storing a 206 as the whole file means every later full request
gets a fragment, and answering a range request with a 200 makes some media stacks
fail outright. So only complete 200s are stored, and ranges are served by slicing
the stored body into a correct 206. The content cache survives shell
re-versioning, or every deploy would re-download the playlist over a link that may
be exactly what is broken.

SELF-UPDATE. The package can replace autorun.brs, so a truncated file is a dark
panel with no app underneath. The safety is the ordering: download to .part,
verify sha256 AND size, then delete the .done marker, rename, reboot. Marker
first is not stylistic — leaving it makes the next boot skip the archive and the
update silently never happens. A failed extract parks the zip as .bad instead of
retrying every boot, which would be a loop indistinguishable from a hardware
fault. sha256 because that is what roMessageDigest can compute; a checksum the
player cannot verify is an unverifiable package.

The decision lives on the server and is unit-tested, and the host only executes
it — re-implementing the version comparison in BrightScript would put the
prerelease trap somewhere untestable. That trap is honoured directly: a player on
1.9.29-rc1 is running something semver-OLDER than 1.9.29, so an opted-in player
HOLDS a prerelease of its own core rather than being pulled off the build it was
given to test. Narrowly — a newer core still lands, so opting in never means
never updating again.

Both loop conditions are closed by construction. The manifest and the download
come from one buffer hashed once, so a checksum cannot describe bytes we are not
serving. And the version is stamped into autorun.brs at build time by both
builders, so the script reports the version it actually is — otherwise the player
applies the update, still reports the old version, and is offered the same
package forever.

Failure always degrades to "keep running the old version": an unreachable
manifest, a missing checksum, a failed verification, a full attempt counter and
an unbuildable package all resolve to skip.

998 tests pass (was 954).

ScreenTinker 5901067d8a Finish the BrightSign port: native sync, offline fallback, multicast guard
st-sync.js wraps SyncManager, the native protocol. Three properties drove the
shape of it. It repeats the sync broadcast at 1Hz so a player powered on late
still joins, which means acting on every repeat would reload the video once a
second forever — on screen that reads as a stutter, not as a sync fault, so the
id dedupe is mandatory rather than an optimisation. The leader starts from its
OWN broadcast rather than at announce() time, or it runs ahead of the group by
the width of the network. And attachVideo refuses an element with no
setSyncParams instead of half-syncing it.

offline.html is the local fallback the host falls back to after three failed
loads. It names the server, keeps probing with capped backoff so a site full of
panels cannot storm a server that is coming back, and asks the HOST to restart
the player when it answers — never navigating itself, for the same reason the
player never reloads itself here.

The resolver now models multicast reach. All-BrightSign groups spread across
subnets no longer get native sync: each subnet would sync neatly within itself
while drifting from the others, and the dashboard would show a healthy group
throughout. The IP comparison is a heuristic so it is used in one direction
only — differing networks are evidence against, matching ones are never proof
for, and unknown addresses block nothing.

st-sync.js is served from its single source like the bridge, and the SD card
deliberately carries neither: the player pulls both from the server so a stale
copy on a card can never skew from the player using it.

948 pass.

ScreenTinker 6f5907a1d4 BrightSign: supervised player host, JS bridge, and per-group sync backend
The player is the unmodified web player in an roHtmlWidget — that already runs
on real hardware. What was missing is everything a page cannot do for itself.

autorun.brs becomes a host rather than a URL wrapper. It owns the widget
lifecycle, because a page-initiated location.reload() does not reliably bring an
roHtmlWidget back: a deploy on 2026-07-28 reloaded every connected player and
the BrightSign was the only one that never returned. The page now posts
{type:"restart"} and the host rebuilds the widget. It also retries load-error
with backoff, falls back to a local page, and runs a heartbeat watchdog that
catches the case load-error never reports — a page that loaded fine and then
wedged on a dead socket or a stalled decoder.

st-bridge.js is the page's half over @brightsign/messageport: registry-backed
identity (localStorage is origin- and quota-bound, the registry is not),
restart-instead-of-reload, heartbeat, and sync-backend reporting. Every method
degrades to a no-op off-platform, so it is safe to load unconditionally.

sync-backend.js decides whose synchronisation a group runs. Ours is
clock-derived and spans any mix of Android, web, Tizen and BrightSign; BrightWall
is frame-accurate and BrightSign-only. auto picks native when every member is a
BrightSign. The refusal that matters: native sync selected for a mixed group
downgrades and says why, because a half-synced group would look perfectly
synchronised on the dashboard while one panel drifted alone.

Dual output via output_mode single|dual|clone — a second widget loads the same
player with &screen=2 so the server can give it its own playlist.

Written against the BrightDeveloper docs; not yet run on hardware. The README
lists what is unimplemented, including the BrightWall runtime API, which that
doc set does not cover.

Claude 9c6b80c411 Apply a saved device snapshot only inside the workspace it was taken in
Per-device settings are saved against the hardware fingerprint so a panel that is deleted and paired
again comes back configured — name, orientation, playlist, blocked flag — without anyone visiting
it. That is deliberate and worth keeping.

A fingerprint is hardware-derived, so the same physical panel presents the same one whoever pairs
it. applyToDevice looked the snapshot up on fingerprint alone with no workspace comparison, and its
per-field guards only check that the referenced row still EXISTS, never who it belongs to:

    if (s.playlist_id && db.prepare('SELECT 1 FROM playlists WHERE id = ?').get(s.playlist_id))

So a screen removed from one workspace and paired into another inherited the first workspace's
playlist and displayed its content, and `blocked` crossed the same way — a device arriving blocked
with nothing the new owner could see to explain it. The manual restore route already compares
workspaces before calling this, so the automatic re-pair path was the only place the check was
missing.

A mismatch is a quiet no-op rather than an error: re-pairing a second-hand panel into a different
workspace is a legitimate thing to do, it just must not carry the previous configuration along. A
snapshot with no workspace recorded still applies, so rows predating the column keep working.

5 tests: neither playlist nor block crosses, a mismatch does not throw, restore still works in full
inside the owning workspace (including a genuine block surviving a re-pair), and legacy rows are
unaffected. 882 server tests green.
