prerender-v0.8.2 — @harperfast/prerender

Fixes queue resume, which reported the opposite of what it did in v0.8.1. Anyone on 0.8.0 or 0.8.1 should upgrade — see PR #33.

The bug

setPause writes the intent and then re-resolves it in the same request. A row deleted earlier in that request is still visible to the read, so a resume re-read the row it had just deleted, resolved straight back to "paused", and returned that as the outcome:

POST /prerender_admin/queue {"scope":"localhost","paused":null}
  -> local: { status: 'paused', paused: true, source: 'node' }    # reports still-paused
GET  /queue_control/                     -> []                    # the row WAS deleted
POST (identical call, second request)    -> { paused: false, source: 'default' }   # correct

v0.8.1's projection bug had been masking this. The node did recover on the next status-sync tick (~1m), so the practical damage was an API that lied about the outcome — and an operator retrying a resume that looked stuck.

Fix

The just-written scope is passed to getDesiredPause as pending, substituting that value instead of reading it back; the other scope is still read normally since the write didn't touch it. This removes the dependency on write visibility for both put and delete rather than special-casing the delete. The value threaded through is the normalized intent.paused, so the resolved and persisted states are identical by construction.

Also dedupes knownScopes, which listed all twice whenever a cluster control row existed.

Verified against a live instance

The full matrix, on a real Harper instance rather than only in tests:

Action	Result
pause node	paused: true, source: node
claim	[]
resume node (paused: null)	paused: false, source: default ← was paused: true, source: node
claim	jobs returned
cluster pause	paused: true, source: cluster
claim	[]
node override paused: false	paused: false, source: node — runs through the cluster pause
clear node override	paused: true, source: cluster — falls back correctly

Plus all three validation rejections (unknown scope, all + null, non-boolean).

Tests

160 pass. The new read-side suite uses fakes that reproduce Harper's projection and write-visibility behavior, so both defects fixed across 0.8.1/0.8.2 are now pinned: with either fix reverted, 4 cases fail.

Unaffected

Read-only surfaces are unchanged and were verified live: the admin page and its CSP headers, session/login, effective config with secret redaction, the overview (counts, node list, due histogram), and the URL explainer.
