R3-1 (high): v1.45.0 made the upload safe but left deletion to the client —
after a successful save the card asked the backend to remove everything but the
file it had just committed. Two open editors cannot be ordered: a delayed
request from one deleted the plan the other had just saved, leaving the
accepted configuration pointing at nothing, the exact damage copy-on-write was
introduced to prevent.
houseplan/plan/cleanup is removed. config/set collects inside its own write
lock from the two configurations that bracket the commit (plans.collect_plans):
a file the old revision referenced and the new one does not is superseded and
goes; any other unreferenced upload waits out PLAN_ORPHAN_TTL_S, because a
fresh one may belong to a transaction that has not committed yet. The collector
lives in a pure module so it can be reasoned about and unit-tested without the
HA harness.
R3-2: houseplan-space-card signed its plan url and threw the result away —
getCardSize() mutated a throwaway model while render() rebuilt its own from the
config, so the <image> requested the protected path and got 401 on every
render. Both cards now share ContentSigner (src/signing.ts), which also gives
the static card batching, expiry handling and periodic re-signing. is
released in finally: one failed request no longer wedges a url for the life of
the page.
Tests: five backend interleaving cases from the report, six unit tests for the
pure collector, smoke_space_card_bg (verified to fail against a v1.45.0 build:
the raw url reaches the DOM and no retry happens). 57 smokes, 124 unit, 22
backend-pure.

The v1.43.0 auth fix closed the hole but left the DISPLAY path
unauthenticated: HA authenticates by a Bearer header or an authSig
signed path, and an <image href> / <a href> sends neither, so plan
backgrounds and manual links returned 401. Reproduced live before the
fix (fetch 401, Image onerror).
- new WS houseplan/content/sign mints async_sign_path urls (24 h,
bound to the connection's refresh token, only for our own endpoint)
- the card resolves display urls through _display(): signed when known,
requests a batched signature otherwise, re-renders when it lands, and
drops all signatures every 12 h so long-lived wall tablets stay valid
- houseplan-space-card signs its background too
- backend test asserts the unsigned url is refused and the signed one
returns the bytes WITHOUT an Authorization header
