Subject: [PATCH 01/28] test(11b): un-quarantine nostr-boost-actions +
 admin-list-store
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Triaged two more silently-excluded test files back into CI.

- nostr-boost-actions: STALE SPEC. Test required buildRepostEvent to throw
  /missing-event-relay/ with no relay hint, but a relay hint is a NIP-18 SHOULD
  (not MUST) — the builder degrades to a two-element `e` tag so a user can always
  repost. Replaced with an exact assertion of the valid output (kind 16 + e/p/k).

- admin-list-store: STALE HARNESS (no production change, no assertion weakened).
  Community curator lists are fetched via the batched SubscriptionManager
  (cold-start relay-storm fix) the harness never mocked; the mock "hex" curator
  values started with "npub" so parseCommunityBlacklistReferences decoded them
  twice; and createListEvent omitted the `d` tag selectNewestEventsForReferences
  matches on. Fixed all three to be faithful to production.

Removed both from the QUARANTINE map; TEST_INTEGRITY.md + TODO updated.

+      nostr-boost-actions: STALE SPEC. The test required buildRepostEvent to throw
+      /missing-event-relay/ when no relay hint is given, but a relay hint is a NIP-18
+      SHOULD (not MUST). The builder intentionally degrades to a two-element `e` tag so a

+      admin-list-store: STALE HARNESS, no production change, no assertion weakened. Three
+      fidelity fixes so the test exercises the real batched community-blacklist path:
+      (1) curator lists are now fetched via the batched SubscriptionManager (cold-start
+      relay-storm fix), which the harness didn't mock — added a getSubscriptionManager().list
+      mock serving the same registry; (2) curator coordinates now use REAL 64-char hex
+      pubkeys (the old mock-"hex" started with "npub", so parseCommunityBlacklistReferences'
+      isHexPubkey()/npub branch decoded them twice and the batched filter no longer matched);
+      (3) createListEvent now emits a `d` tag (real kind-30000 lists always have one;
+      selectNewestEventsForReferences matches curator events to references by their d tag).
+  relaxation:
+    did_relax_any_assertion: false

 publish-rejection setup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

nostr-count-fallback: STALE TEST after a refactor — countUnsupportedRelays moved
from NostrClient to its ConnectionManager, and the test read it off the client
(undefined.has). Repointed the assertion at client.connectionManager
.countUnsupportedRelays. No behavior change, no assertion weakened.

Also recorded the precise multi-precondition diagnosis for the still-quarantined
nostr-publish-rejection (dev-mode override before the first dynamic config import;
then a NIP-71 invocation sub-test) in the QUARANTINE note + TODO, so it's a quick
finish next time.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From 2026-06-25 user report:
- #33 (HIGH): NIP-46/Amber login+profile+persistence broken — "unknown user" /
  no videos until logout+hard refresh, profile switching broken, logout logs out
  all accounts; audit the login/profile/session-persistence system.
- #34: NIP-71 mirror shows mirrored videos as "not mirrored"; re-mirror creates
  duplicates in NIP-71 clients; make detection reliable + the publish idempotent.
- #35: admin whitelisting tool slow/cumbersome — improve alongside #22/#23.
- #36: storage unlock fails with nsec login.
- #37: channel playlists (creator-curated note lists).
- #38: generic S3 doesn't work with Backblaze B2 (endpoint/public-URL mismatch) —
  add B2 as its own provider.
- #39: image uploads (profile image/banner first) should prefer uploading to the
  user's configured storage and auto-grab the URL.
- #7: broadened to "improve mobile UI" across the app, not just the card.

+Reported 2026-06-25. All symptoms observed with a **NIP-46 remote signer (Amber)**.

+- [ ] **Switching profiles doesn't work** for logged-in users (multi-account switch is

+- [ ] **Logout logs out everyone.** Logging out the current user appears to log out

+      instead of per-account).
+- [ ] **Audit the whole login + profile system + user persistence** across refresh and
+      repeat visits — especially the NIP-46 path: how the active pubkey + signer
+      connection are stored/restored, how multiple accounts are tracked, and how
+      logout scopes to one account. Produce a plan (likely `docs/`), then fix.

+### 34. NIP-71 mirror: videos show "not mirrored" + duplicate on re-mirror (BUG)
+Reported 2026-06-25. Relates to #17 (NIP-71 interop) / the bitvid→NIP-71 mirror.
+- [ ] **Mirrored videos report as NOT mirrored.** All videos were mirrored, but the UI
+      now shows them un-mirrored even though the NIP-71 mirror events exist. The
+      "is this mirrored?" detection is wrong/stale (likely the mirror-state lookup

+- [ ] **Re-mirroring creates DUPLICATES.** Because they read as un-mirrored, mirroring

+      same video. The mirror should be idempotent (addressable/replaceable, or detect
+      the existing mirror and update it) instead of creating a duplicate.
+- [ ] Delete/un-mirror correctly removes BOTH copies (so the dedup key is shared) —
+      confirms the publish path is creating a true duplicate, not a distinct event.
+- [ ] Fix: make mirror detection reliable + the mirror publish idempotent. See

+
+### 35. Admin whitelisting tool is slow & cumbersome — improve with application forms
+- [ ] The current admin whitelist tool is slow and clunky to use. Improve the UX when
+      we integrate the **application/submission forms** (#22) and the **Admin
+      Submissions tab** (#23) — e.g. approve-an-application → add-to-whitelist in one
+      action, batch operations, and faster list mutation. Couples with #22/#23.
+
+### 36. Storage unlock doesn't work with nsec login (BUG)
+- [ ] With an **nsec** login, unlocking encrypted storage credentials fails. The
+      storage-unlock flow likely assumes a different signer/key path than the nsec
+      session provides. Audit the unlock path (`StorageService` master-key decrypt +
+      `js/services/authService.js`) for the nsec case so nsec users can use hosted
+      storage. (Relates to the credential-encryption work in #15.)
+
+### 37. Channel playlists — creator-curated custom note lists
+- [ ] Let creators build **playlists** (custom curated lists of their videos / notes)
+      surfaced on their channel. Likely a NIP-51 set (kind 30005 "curation sets" or a
+      bitvid-specific addressable list) referencing video events, with create/edit/
+      reorder UI on the channel page and a playlist view. Research the list shape +
+      where it slots into channel profile + the feed engine.
+
+### 38. Generic S3 doesn't work with Backblaze B2 — add B2 as a first-class provider
+- [ ] Backblaze **B2** fails under the generic-S3 path: B2's model doesn't map cleanly
+      onto the assumed endpoint / public-access-URL fields (one of them is derived
+      differently), so credentials fail to fetch/validate. Investigate B2's S3-compatible
+      endpoint + friendly-URL/`f000`-style download host, and likely add **B2 as its own
+      provider** (`PROVIDERS`) with B2-specific endpoint + public-URL derivation rather
+      than forcing it through generic S3. See `js/services/storageService.js` /
+      `s3Service.js` (provider abstraction from #6).
+
+### 39. Image uploads should prefer uploading to configured storage (UX)
+- [ ] Anywhere the user adds an image, prefer letting them **upload an image file to
+      their configured storage** (Cloudflare R2 / S3 / B2 / Blossom) and auto-grab the
+      resulting URL — rather than pasting a link. First target: the **profile image +
+      banner** in Edit Profile (upload → store → auto-fill the URL). Reuse the existing
+      upload pipeline (`s3UploadService` / thumbnail upload) and apply the same pattern
+      to other image inputs (thumbnails already do some of this).

Subject: [PATCH 04/28] feat(mobile): sidebar nav becomes an app-grid on mobile
 (#7)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Below the desktop breakpoint (<1024px), the open/expanded sidebar's primary nav
renders as a 3-column grid of icon tiles with the title centered below each icon
(app-grid feel), instead of the desktop vertical list. Desktop and the collapsed
icon rail are unchanged.

- Scoped to `.sidebar-nav` so the footer "More" links are untouched.
- Token-only (no raw measurements), high specificity via the sidebar-expanded
  prefix (no !important). Labels wrap at spaces, not mid-word.
- Validated live in-browser; lint clean.

Option A (grid shows on the open mobile menu). An always-on variant was deferred —
it would require widening/overlaying the mobile sidebar.

Subject: [PATCH 06/28] feat(mobile): profile modal tabs become an app-grid
 (#7)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On mobile (<1024px, the full-width menu view), the profile modal's tab nav
(Account, Relays, Wallet, Storage, …) renders as a 3-column grid of icon tiles
with the title centered below each icon, instead of the vertical list. Desktop
(>=lg) keeps its vertical nav, unchanged.

Scoped to `.profile-modal__nav` inside the existing mobile media query; token-only;
labels wrap at spaces. Validated live in-browser.

(Note: the earlier sidebar app-grid was a misread of the request and was reverted;
this is the intended component.)

Subject: [PATCH 08/28] fix(mobile): profile-modal grid was in a dead @media
 block (var() in condition)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The profile-modal nav app-grid never applied because its @media condition used
`calc(theme("screens.lg") - var(--breakpoint-edge-offset))` — CSS custom
properties are invalid inside @media conditions, so Chromium/Brave drop the whole
block (confirmed via matchMedia). My earlier in-browser preview used !important,
which bypassed the media query and masked it.

Moved the grid rules into a valid `@media (max-width: theme("screens.lg"))` block
(theme() resolves to a literal at build time). Cascade verified without !important:
display:grid, 3 columns, flex-direction:column. Lint clean.

Filed #40: the same var()-in-@media pattern silently breaks many other responsive
rules (it was added to satisfy the token lint) — needs a broader audit.

Subject: [PATCH 09/28] fix(css): replace var() in @media conditions with
 literal (#40)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CSS custom properties are invalid inside @media conditions — Chromium/Brave drop
the whole block — so every `@media (max-width: calc(theme("screens.lg") -
var(--breakpoint-edge-offset)))` was DEAD. The offset token was added to satisfy the
design-token lint, but `0.02px` is already exempt there, so the token was never
needed and silently broke the queries.

Swapped var(--breakpoint-edge-offset) → 0.02px in all 4 @media conditions (valid,
lint-clean, exclusive breakpoint preserved). Verified valid via matchMedia. This
re-activates 3 previously-dead mobile blocks that were intended but never worked:
full-screen modals on mobile, profile-modal menu/pane switching, and the video-card
tap-active state (plus the profile-nav app-grid).

Subject: [PATCH 10/28] diag(nip46): add temporary lifecycle diagnostics for
 #33
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Code-level audit of the NIP-46/Amber login+profile+persistence bug points at a
single shared SignerManager.nip46Client + per-profile restore/switch not being
multi-account-aware. Added TEMP [nip46-diag] userLogger traces (visible on
unstable; devLogger is gated off there) at:
- scheduleStoredRemoteSignerRestore (restore-on-load → "unknown user")
- disconnectRemoteSigner (the shared-client teardown → "logs out everyone")
- SignerManager.logout (scope)
- authService.switchProfile (does the switch resolve the expected pubkey)

These let a single Amber reproduction pinpoint the exact failure before the fix.
Findings + plan recorded under TODO #33. Remove diagnostics with the fix.

+      symptoms: the single-shared `nip46Client` + per-profile restore/switch not being
+      multi-account-aware. Specifics:
+        - **Logout-logs-out-everyone:** `authService.logout()` IS registry-scoped
+          (`logoutSignerFromRegistry(previousPubkey)`), but `SignerManager.logout()`
+          calls `disconnectRemoteSigner()` which destroys the SHARED `nip46Client` — so
+          for NIP-46 every profile that depends on it loses its signer.
+        - **Switch-doesn't-work:** `authService.switchProfile` re-runs `requestLogin`
+          with `expectPubkey`; for NIP-46 the shared client must be re-established for the
+          target profile — if it doesn't reconnect, the new profile has no working signer.
+        - **Unknown-user-after-refresh:** `scheduleStoredRemoteSignerRestore` →

+          `devLogger`), leaving `this.pubkey` unresolved → UI shows "unknown user".

 - [ ] Fix: make mirror detection reliable + the mirror publish idempotent. See
       `js/nostr/nip71Mirror.js` / `js/services/nip71MirrorFlags.js`.
 
+- [x] **AUDIT done 2026-06-25.** Two root causes:
+      1. **Detection is device-local.** `isMirrorEnabled(pubkey, videoRootId)`
+         (`nip71MirrorFlags.js`) reads a localStorage flag (`FLAG_KEY`), NOT the actual
+         published mirror events — so a cache clear / other device / lost flag reports
+         "not mirrored" even though the 34235/34236 events exist on relays.
+      2. **Kind is unstable → cross-kind duplicate.** `buildNip71MirrorEvent`
+         (`nip71Mirror.js:177`) uses `short = hasDims && height > width` → kind 34236,
+         else 34235. The d-tag is deterministic (`["d", videoRootId]`), but
+         `(34235,pubkey,d)` and `(34236,pubkey,d)` are DISTINCT addressable events. When
+         a video has dimensions on one mirror attempt but not another, the kind flips, so
+         re-mirroring publishes the OTHER kind → two copies in NIP-71 clients. "Delete
+         removes both" confirms the shared d-tag / two-kind duplicate.
+- [ ] **FIX PLAN:**
+      (a) **Idempotent publish:** before mirroring, query relays for an existing mirror
+          by author + `#d=videoRootId` across BOTH kinds; if one exists, REUSE its kind
+          (replace it) and delete any stray of the other kind. Going forward also make
+          the kind determination stable (don't flip to 34235 just because dims are absent
+          — fall back to the existing/previous kind).
+      (b) **Relay-truth detection:** derive "is mirrored" from the published events (the
+          query above), not just the local flag; keep the flag as a cache/hint only.
+      Reproduction-dependent (needs NIP-71 relay state) — verify on unstable after.

Subject: [PATCH 13/28] fix(mirror): idempotent NIP-71 re-mirror + self-heal
 cross-kind duplicates (#34)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The mirror kind (34235 normal / 34236 short) is inferred from the video's
dimensions, but (kind,pubkey,d) is the addressable identity — so re-mirroring with
different dims published the OTHER kind and showed the video TWICE in NIP-71
clients.

nip71MirrorService.publish() now looks up the author's existing mirror (both kinds,
via the SubscriptionManager chokepoint) and REUSES the existing kind so a re-publish
replaces the same coordinate. If both kinds already exist (the bug's aftermath), it
self-heals by NIP-09-deleting the stale-kind coordinate. Explicit options.short still
wins. Added findMirror(video) for relay-truth detection ({mirrored,kinds,duplicate}).

Dependency-injected; 4 new scenario tests (12/12 green); lint clean. Follow-up (b):
wire findMirror into MyVideosController so the UI toggle reflects relay truth instead
of the device-local flag.

-          the kind determination stable (don't flip to 34235 just because dims are absent
-          — fall back to the existing/previous kind).
-      (b) **Relay-truth detection:** derive "is mirrored" from the published events (the
-          query above), not just the local flag; keep the flag as a cache/hint only.

Subject: [PATCH 14/28] [ui] #34(b): My Videos mirror toggle reflects relay
 truth, not just the local flag

The per-row "Share to apps" toggle read only the device-local opt-in flag
(nip71MirrorFlags), so a fresh device / cleared cache / other device reported a
video as un-shared even when its NIP-71 mirror events (34235/34236) exist on the
user's relays.

- nip71MirrorService: add batched findMirrors(videos) -> Map<videoRootId,
  {mirrored, kinds, duplicate}>, one lookup per root via the SubscriptionManager
  chokepoint (no direct pool.list).
- MyVideosController: tag each mirror button with data-mirror-root; after the
  synchronous (local-flag) render, refreshMirrorStates() looks up relay truth,
  reconciles the local flag to match (flag stays a cache hint), and corrects each
  button label. Fire-and-forget; detection failures fall back to the local flag.
- tests/my-videos-mirror-relay-truth.test.mjs: 4 jsdom behavioral tests
  (promote unmirrored->shared, clear stale shared, per-row batch reconcile,
  button tagging). Build + lint clean; mirror+my-videos suites 48/48.

Subject: [PATCH 15/28] [ui] #36: clear, actionable storage-unlock error for a
 locked nsec session after reload
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Root cause (user-confirmed repro): a persisted "remember this key" nsec session
restores the logged-in pubkey + UI on reload, but NOT the in-memory signer (the
private key is only passphrase-encrypted). Storage unlock then has no signer, and
the fallback (ensureActiveSignerForPubkey) can only rebuild an EXTENSION signer —
so an nsec user dead-ended on the misleading "No active signer found. Please login."
even though they still look logged in. The crypto layer itself is correct: an
empirical repro shows storageService.unlock round-trips master-key encrypt/decrypt
fine with real nsec cipher closures.

Fix: detect the locked persisted-nsec case (getLockedStoredNsecSession via
getStoredSessionActorMetadata, scoped to the account being unlocked) and surface an
actionable error/status ("re-enter your passphrase from the Login menu to unlock
your saved key, then unlock storage") in both the Unlock-button flow and the passive
Storage-pane status text, instead of the generic no-signer / no-decryptor messages.
New error code storage-unlock-locked-nsec-session.

Tests: tests/storage-unlock-locked-nsec.test.mjs (6 behavioral). Build + lint clean;
existing storage-service tests still 14/14.

 ### 36. Storage unlock doesn't work with nsec login (BUG)
-- [ ] With an **nsec** login, unlocking encrypted storage credentials fails. The
-      storage-unlock flow likely assumes a different signer/key path than the nsec
-      session provides. Audit the unlock path (`StorageService` master-key decrypt +
-      `js/services/authService.js`) for the nsec case so nsec users can use hosted
-      storage. (Relates to the credential-encryption work in #15.)
+- [x] **ROOT-CAUSED + FIXED 2026-06-29.** Audited the whole nsec unlock path and built
+      an empirical repro: the crypto layer is **correct** — with real nsec cipher
+      closures (`createPrivateKeyCipherClosures`), `storageService.unlock` round-trips
+      master-key encrypt→lock→decrypt perfectly (NIP-44). Both nsec login paths
+      (`registerPrivateKeySigner`, `unlockStoredSessionActor`) register a signer exposing
+      `nip04Decrypt`/`nip44Decrypt`. **The real failure is session-shape after a page
+      reload** (user-confirmed repro): a persisted "remember this key" nsec session
+      restores the logged-in **pubkey + UI but NOT the in-memory signer** (the private key
+      is only passphrase-encrypted). `ProfileStorageController`'s fallback
+      (`ensureActiveSignerForPubkey`) can only rebuild an *extension* signer, so an nsec
+      user hit a dead-end: storage unlock found no signer and showed the misleading "No
+      active signer found. Please login." even though they look logged in.
+      **Fix:** detect this exact case (`getLockedStoredNsecSession` — a saved nsec key for

+      `tests/storage-unlock-locked-nsec.test.mjs` (6, behavioral). Build + lint clean.
+- [ ] **Follow-up (UX nicety):** auto-open the login modal's existing unlock-saved-key
+      (passphrase) flow directly from the storage pane so the user re-unlocks in one
+      click instead of navigating to Login — needs a side-effect-free
+      `requestUnlockStoredSession` hook (the current `requestAddProfileLogin` path runs an
+      add-account callback). Deferred to keep this fix small.
+- [ ] **VERIFY on unstable:** nsec-login with "remember key" + passphrase, reload the
+      page, open Profile → Storage → the status should read the actionable re-unlock hint
+      (not "No active signer"); after re-entering the passphrase via Login, storage
+      unlocks normally. (`[storage-unlock]` console line confirms the locked-key branch.)

Subject: [PATCH 16/28] [ui] #36: auto-open the unlock-saved-key flow from
 storage when an nsec session is locked
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to the locked-nsec detection: clicking "Unlock Storage" on a locked
persisted-nsec session (no in-memory signer after a page reload) now auto-opens the
login modal straight to its existing unlock-saved-key (passphrase) flow, so the user
re-unlocks in one step instead of hunting for the Login menu. Once unlocked, the
signer is active app-wide and re-opening the storage pane auto-unlocks.

- applicationBootstrap: add a side-effect-free openLoginModal service to
  profileModalServices (app.loginModalController.openModal — no add-account callback;
  idempotently ensures the modal is initialized first).
- ProfileStorageController: reportLockedNsecSession({ autoOpenLogin }) opens the modal
  only from the user-initiated unlock click, never from the passive pane render (no
  surprise popups).
- Tests extended to 8 (auto-open fires on click; stays closed on passive render).

Build + lint clean.

Subject: [PATCH 17/28] [storage] #38: add Backblaze B2 as a first-class
 storage provider
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

B2 doesn't map onto the generic-S3 "paste an endpoint" model: its S3-compatible
endpoint is region-scoped (s3.<region>.backblazeb2.com) and a public bucket is
addressed virtual-hosted-style, so the public download URL is
https://<bucket>.s3.<region>.backblazeb2.com/<key> — not derivable from a pasted
generic endpoint. So B2 silently failed under "Custom S3".

- s3-url: deriveB2Endpoint(region) -> https://s3.<region>.backblazeb2.com (empty for
  auto/blank/pasted-host so callers can require a real region); re-exported from
  s3Service.
- storageService: PROVIDERS.B2 + resolveB2Endpoint (explicit endpoint wins, else
  derive) + PROVIDER_TESTS[B2] (derived endpoint, forcePathStyle false).
- Public URL = S3-style virtual-hosted, auto-derived; an explicit Public Access URL
  (custom domain/CDN) overrides it. The save path now forwards the user's public URL
  to prepareS3Connection (also fixes generic-S3 ignoring a custom CDN URL when blank
  -> still derives, so no regression).
- UI: "Backblaze B2" provider option + helper; raw Endpoint hidden for B2 (region
  drives it), region shows a us-west-004 example, force-path-style toggle hidden;
  save/test derive endpoint from region with a clear "enter your region" error.
  UploadModal shows B2-specific labels.
- Tests: tests/storage-b2-provider.test.mjs (8). All s3/storage suites green (50);
  build + lint clean.

 ### 38. Generic S3 doesn't work with Backblaze B2 — add B2 as a first-class provider
-- [ ] Backblaze **B2** fails under the generic-S3 path: B2's model doesn't map cleanly
-      onto the assumed endpoint / public-access-URL fields (one of them is derived
-      differently), so credentials fail to fetch/validate. Investigate B2's S3-compatible
-      endpoint + friendly-URL/`f000`-style download host, and likely add **B2 as its own
-      provider** (`PROVIDERS`) with B2-specific endpoint + public-URL derivation rather
-      than forcing it through generic S3. See `js/services/storageService.js` /
-      `s3Service.js` (provider abstraction from #6).
+- [x] **DONE 2026-06-30.** Added **Backblaze B2** as its own provider
+      (`PROVIDERS.B2 = "backblaze_b2"`). Root issue: B2's S3 endpoint is *region-scoped*
+      (`s3.<region>.backblazeb2.com`) and a public bucket is addressed virtual-hosted, so
+      the public download URL is `https://<bucket>.s3.<region>.backblazeb2.com/<key>` —
+      not derivable from a pasted generic-S3 endpoint. Implementation:
+      - `deriveB2Endpoint(region)` (`js/storage/s3-url.js`, re-exported from `s3Service`):
+        region → `https://s3.<region>.backblazeb2.com`; returns "" for `auto`/blank/pasted
+        host so callers can require a real region.
+      - `storageService`: `PROVIDERS.B2` + `resolveB2Endpoint` (explicit endpoint wins,
+        else derive from region) + a `PROVIDER_TESTS[B2]` handler (derived endpoint,
+        `forcePathStyle:false`).
+      - **Public URL strategy = S3-style virtual-hosted** (user-chosen): auto-derives to
+        `https://<bucket>.s3.<region>.backblazeb2.com`; an explicit Public Access URL
+        (custom domain/CDN) overrides it — the save path now passes the user's URL to
+        `prepareS3Connection` (also fixes generic-S3 silently ignoring a custom CDN URL).
+      - UI (`profile-modal.html` + `ProfileStorageController`): "Backblaze B2" option +
+        helper; for B2 the raw Endpoint field is hidden (region drives it), Region shows a
+        `us-west-004` example, force-path-style toggle hidden (B2 is virtual-hosted), and
+        save/test derive the endpoint from region (clear "enter your region" error if
+        missing). `UploadModal` shows B2-specific labels.
+      - Tests: `tests/storage-b2-provider.test.mjs` (8 — endpoint derivation, virtual-
+        hosted public URL, end-to-end validate, explicit override, object URLs). All
+        s3/storage suites green (50); build + lint clean.
+- [ ] **VERIFY live** with a real B2 Application Key + public bucket on unstable: pick
+      Backblaze B2, enter region (e.g. `us-west-004`) + bucket + key/secret, Test → passes;
+      upload a video → plays from `https://<bucket>.s3.<region>.backblazeb2.com/...`.

Subject: [PATCH 18/28] [ui] #38: add a CORS setup helper modal for B2 /
 S3-compatible buckets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Confirmed against the real B2 account: the web-console "Share everything..." presets
write DOWNLOAD-only CORS (s3_get/s3_head, b2_download_*) with NO s3_put/s3_post, so
bitvid's browser uploads CORS-fail. The web UI can't set custom rules — it points
users at the B2 CLI.

Adds a "CORS setup help" button (shown for B2 / Custom S3, hidden for R2) that opens a
modal with:
- the exact CORS rules JSON in B2-native shape (upload + ranged-playback ops; origins
  pre-filled from getCorsOrigins()), with a Copy button,
- the `b2 update-bucket --corsRules '<json>' <bucket> allPublic` command to apply it,
- step-by-step + the "use a key with writeBucketCors and bitvid sets it for you" tip.

CORS logic extracted to js/ui/profileModal/storageCorsHelp.js (pure builders +
StorageCorsHelp modal controller) so ProfileStorageController stays under the 1000-line
cap. Tests: tests/storage-cors-help.test.mjs (8 — asserts the rules include the upload
ops the presets omit, origin pre-fill, command shape, modal open/close/visibility).
Build + lint clean; profile-modal + storage suites 32/32.

Subject: [PATCH 19/28] [ui] #38: make the CORS setup helper provider-aware (R2
 / B2 / Custom S3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first cut showed for Custom S3 too but always gave B2-only instructions (b2 CLI +
B2-native JSON), and was hidden for R2. Now the helper shows for all bucket providers
and tailors its content:

- Backblaze B2  -> B2-native rules + `b2 update-bucket --corsRules ...`
- Custom S3     -> standard S3 CORSConfiguration + `aws s3api put-bucket-cors
                   --endpoint-url <endpoint> ...`
- Cloudflare R2 -> standard S3 JSON + Cloudflare dashboard guidance (R2 -> bucket ->
                   Settings -> CORS Policy) and the AWS-CLI command vs the derived R2
                   endpoint.

Origins pre-filled from getCorsOrigins(); intro/command-label/notes set per provider;
copy buttons for both blocks. bitvid still auto-applies CORS on Save (R2/S3 via
ensureBucketCors) — this is the manual fallback when the key lacks CORS-write perms.

buildCorsHelpContent() switches on provider; modal text is now data-driven. Tests
extended to 10 (per-provider rules + command + a DOM provider-switch). Build + lint
clean; storage suites 40/40.

Subject: [PATCH 20/28] [ui] store storage credentials per provider so R2 / B2
 / S3 don't clash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Storage pane saved every provider into a single shared "default" connection id,
so configuring Backblaze B2 overwrote your Cloudflare R2 (and vice-versa). The service
layer, upload path, and sync already supported a MAP of connections keyed by id
(listConnections / defaultForUploads / exportAccountRecord) — only the UI collapsed
them into one slot.

- Save each provider under its own slot keyed by provider id (cloudflare_r2 /
  backblaze_b2 / generic_s3), preserving a single active defaultForUploads and lazily
  migrating the legacy "default" slot to its provider id.
- Switching the provider dropdown now loads that provider's saved credentials (or
  clears the fields for a fresh entry), so each provider keeps its own creds visibly.
- Sync is unchanged: it already exports the whole account record, so every provider's
  connection syncs together.

Logic extracted to js/ui/profileModal/storageConnections.js (saveProviderConnection +
pure helpers) so ProfileStorageController stays under the 1000-line cap. Tests:
tests/storage-connections.test.mjs (7 — pure default/dup logic + integration proving
R2+B2 coexist with one default, the re-default switch, legacy-"default" migration, and
that the synced record carries both). Storage + profile-modal suites 69/69; lint clean.

Subject: [PATCH 21/28] [storage] #39: fix profile image/banner upload
 (resolveConnection rejected hex pubkeys)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Edit Profile image + banner upload was wired (resolve connection -> uploadFile ->
auto-fill URL) but silently broken: ProfileEditController passes a HEX pubkey to
r2Service.resolveConnection(), which only decoded npub1... strings via safeDecodeNpub.
A hex pubkey therefore resolved to null -> "Storage configuration missing" and the
Upload button stayed disabled even with storage configured. (Thumbnails worked because
mediaUploader calls listConnections(pubkey) directly.)

Fix: resolveConnection() now accepts a hex pubkey OR an npub. The rest of the chain is
already provider-agnostic (resolveConnection returns the defaultForUploads connection's
endpoint/baseDomain/forcePathStyle, uploadFile routes R2 vs generic-S3 by provider,
buildPublicUrl builds the URL), so profile/banner upload now works for R2 / B2 /
Custom S3.

Test: tests/r2-resolve-connection-hex.test.mjs (3 — nip19.decode throws on hex to prove
the hex path is used, plus npub still works and empty returns null). Build + lint clean;
r2/storage suites green.

 ### 39. Image uploads should prefer uploading to configured storage (UX)
-- [ ] Anywhere the user adds an image, prefer letting them **upload an image file to
-      their configured storage** (Cloudflare R2 / S3 / B2 / Blossom) and auto-grab the
-      resulting URL — rather than pasting a link. First target: the **profile image +
-      banner** in Edit Profile (upload → store → auto-fill the URL). Reuse the existing
-      upload pipeline (`s3UploadService` / thumbnail upload) and apply the same pattern
-      to other image inputs (thumbnails already do some of this).
+- [x] **Profile image + banner upload — FIXED 2026-06-30.** The UI was already wired
+      (`ProfileEditController.handleUpload`: resolve connection → `uploadFile` → auto-fill
+      the URL field), but it was **broken**: it passed a **hex** pubkey to
+      `r2Service.resolveConnection()`, which only decoded `npub1…` strings
+      (`safeDecodeNpub`) → hex resolved to `null` → "Storage configuration missing" and the
+      Upload button stayed disabled even with storage configured. (Thumbnails worked
+      because `mediaUploader` uses `listConnections(pubkey)` directly.)
+      **Fix:** `resolveConnection` now accepts a hex pubkey OR an npub. The rest of the
+      chain is already provider-agnostic — `resolveConnection` returns the
+      `defaultForUploads` connection (any provider) with its `endpoint`/`baseDomain`/
+      `forcePathStyle`, `uploadFile` routes R2 vs generic-S3 by provider, and
+      `buildPublicUrl` builds the right URL — so this now works for R2 / B2 / Custom S3.
+      Test: `tests/r2-resolve-connection-hex.test.mjs` (3, with `nip19.decode` throwing on

+- [ ] **VERIFY live:** unlock storage, Edit Profile → upload a picture/banner file →
+      uploads to the active provider's bucket and the URL auto-fills.
+- [ ] **Extend the pattern** to any remaining image-URL inputs that still only accept a
+      pasted link (video thumbnail in upload/edit already uploads via `mediaUploader`).
+      Audit for others (e.g. future channel/branding image fields) and reuse the helper.

Subject: [PATCH 22/28] [ui] #8: one-click "Delete all" for orphaned storage
 objects in My Videos
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The My Videos tab already lists bucket objects no live note references and offers
per-file delete; this adds the bulk action. A "Delete all (N)" button (shown only when
there's more than one orphan) confirms once, then removes every listed key in a single
deleteStorageKeys({ keys, pubkey }) call — which is already array-capable, unlock-gated,
and scoped to the user's prefix. Refreshes the list on success, reports partial results
honestly ("Removed 2 files (1 could not be deleted)"), and surfaces storage-locked as an
unlock prompt instead of a false success.

Tests: tests/my-videos-bulk-orphan-delete.test.mjs (5 — all keys sent in one call,
cancel deletes nothing, storage-locked prompt, partial-count message, empty no-op).
Build + lint clean; My Videos suite 37/37.

Subject: [PATCH 23/28] [ui] B2 storage: use pipx for the CORS CLI install +
 rename secret field to "Application Key"

- CORS setup helper: the Backblaze B2 instructions now say `pipx install b2` instead of
  `pip install b2` (the recommended way to install a CLI tool).
- Storage form: for the Backblaze B2 provider the "Secret Access Key" field is now
  labelled "Application Key" to match B2's own terminology (the secret half of an
  Application Key). Other providers keep "Secret Access Key".

Test updated to assert the pipx instruction. Build + lint clean.

Subject: [PATCH 24/28] [moderation] #25: per-video admin block list (hide a
 single video, not the author)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Admin moderation was author/community-level only. Admins (any editor — same gate as
the author blacklist) can now hide a SINGLE offending video.

- Record: a published kind-30000 NIP-51 list under d-tag bitvid:admin:event-blacklist,
  carrying blocked event ids as `e` tags (NOTE_TYPES.ADMIN_EVENT_BLACKLIST schema).
  Loaded/persisted through the existing admin-list machinery (adminListStore) and cached
  like whitelist/blacklist.
- accessControl: eventBlacklist Set + getEventBlacklist/isEventBlacklisted/
  addToEventBlacklist/removeFromEventBlacklist (editor-gated; normalizes hex or
  nevent/note) + onEventBlacklistChange.
- Render filter already existed (app.blacklistedEventIds, honored by every feed/grid/
  search/playback path) but was fed only by the static ADMIN_INITIAL_EVENT_BLACKLIST
  config. app._rebuildBlacklistedEventIds() now merges that static base with the dynamic
  admin list, and an onEventBlacklistChange listener rebuilds + refreshes grids on change.
- UI: a "Block this video" item in the per-video ⋯ menu (editor-only), handled by
  handleBlacklistEventAction (js/ui/moreMenu/blacklistEventAction.js).

Helpers extracted to js/adminEventBlacklistHelpers.js to keep adminListStore /
accessControl / moreMenuController under their size caps. Tests:
tests/admin-event-blacklist.test.mjs (9). Build + lint clean; admin/access/moderation
suites 56/56.

 ### 25. Per-video / per-event admin block list (granular moderation)
-- [ ] Today admin moderation is essentially a "ban hammer" (author/community level).
-      Add a **per-event (per-video) block list** so an admin can hide a SINGLE
-      offending video without blocking the whole author. Define the per-event block
-      record (kind/addressable + the event id / address it targets), wire it into the
-      render-time filter alongside the existing author/community blacklist, and expose
-      it in the moderation UI (and eventually the #23 admin tab).
+- [x] **DONE 2026-06-30 (full vertical slice).** Admins (any editor — same gate as the
+      author blacklist) can now hide a SINGLE video without blocking its author.
+      - **Record:** a published kind-30000 NIP-51 list under d-tag
+        `bitvid:admin:event-blacklist`, carrying blocked event ids as `e` tags
+        (`NOTE_TYPES.ADMIN_EVENT_BLACKLIST` schema; `participantTagName: "e"`).
+        Loaded/persisted through the existing admin-list machinery
+        (`adminListStore` loadNostrState/persistNostrState) and cached like the others.

+        `isEventBlacklisted()`/`addToEventBlacklist()`/`removeFromEventBlacklist()`
+        (editor-gated, normalizes hex or nevent/note) + `onEventBlacklistChange`.
+      - **Render filter:** already existed (`app.blacklistedEventIds`, honored by every
+        feed/grid/search/playback path) but was fed only by the static
+        `ADMIN_INITIAL_EVENT_BLACKLIST` config. Now `app._rebuildBlacklistedEventIds()`
+        merges that static base with the dynamic admin list, and an
+        `onEventBlacklistChange` listener rebuilds + refreshes the grids on change.
+      - **UI:** a "Block this video" item in the per-video ⋯ menu (editor-only, via
+        `videoMenuRenderers`), handled by `handleBlacklistEventAction`
+        (`js/ui/moreMenu/blacklistEventAction.js`).
+      - Helpers extracted to `js/adminEventBlacklistHelpers.js` to keep adminListStore /

Subject: [PATCH 25/28] [ui] upload modal: prompt for the nsec passphrase
 instead of dead-ending after reload
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With a persisted ("remember this key") nsec login, uploading a video after a page
reload reported "storage is locked" and then "No signer available to unlock storage."
The reload restores the logged-in pubkey but NOT the in-memory signer (the key is
passphrase-encrypted), and UploadModal.handleUnlock dead-ended on the alert — it never
asked for the passphrase.

Fix (mirrors the storage pane's #36 behavior): handleUnlock now calls
promptStoredNsecUnlock(pubkey) when there's no usable signer. If the active account has
a locked saved nsec key (getStoredSessionActorMetadata), it shows an actionable message
and opens the login modal's existing unlock-saved-key (passphrase) flow via a new
onRequestUnlock hook (wired in initUploadModal -> app.loginModalController.openModal),
instead of the dead-end alert. After the user re-enters their passphrase the signer is
active and the upload proceeds.

Tests: tests/upload-modal-nsec-unlock.test.mjs (5 — detects locked nsec for the active
account + opens unlock; ignores missing/non-nsec/other-account; falls through with no
hook). Build + lint clean.

Subject: [PATCH 26/28] [ui] upload: route by the credentials' own provider
 (fix "S3 endpoint is required")
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With both Backblaze B2 and Cloudflare R2 configured, an upload could fail with "S3
endpoint is required." when the upload modal's tracked provider drifted out of sync
with the active credentials (user: storage selector on Backblaze but the modal set for
Cloudflare). A Cloudflare R2 connection stores an accountId and derives its endpoint, so
routing it through the S3 service — which requires an explicit endpoint — threw.

Fix: MediaUploader.uploadVideo/uploadThumbnail now choose the service + provider from the
CREDENTIALS' own provider (credentials.provider || credentials.meta.provider || provider),
so a stale modal provider can no longer send an R2 connection through the S3 path (or
vice-versa). The R2 service derives the endpoint from accountId as before.

Test: tests/media-uploader-provider-routing.test.mjs (4 — R2 creds route to r2Service
even with a stale Backblaze arg; B2 creds route to s3Service; meta.provider + passed-arg
fallbacks). Build + lint clean; upload/storage suites green.

Subject: [PATCH 27/28] [ui] fix: nsec PIN/passphrase field unclickable when
 login opens over the profile modal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Opening the login modal's unlock-saved-key (nsec passphrase/PIN) field on top of the
profile modal left it unclickable/untypable. The profile modal's document-level focusin
trap yanks focus back to itself whenever focus leaves the modal — but it didn't
recognize a modal STACKED on top (the login modal is also a .bv-modal), so it stole
focus away from the PIN field the moment it was clicked.

Fix: the focusin trap now yields when the focus target is inside a different OPEN
.bv-modal (isInStackedModal, extracted to js/ui/focusTrapStacking.js so it's unit-
testable without constructing the whole controller). The stacked login modal keeps focus
and the field is typable again. This also makes the trap robust for any future stacked
modal, not just the #36 re-unlock flow.

Test: tests/focus-trap-stacking.test.mjs (5 — yields to an open stacked modal's field;
does not yield within the trapping modal, to a hidden modal, to a bare target, or on a
null/non-element). Build + lint clean; profile-modal suite green.

Subject: [PATCH 28/28] =?UTF-8?q?[storage]=20fix=20B2=20/=20generic-S3=20u?=
 =?UTF-8?q?ploads=20("S3=20endpoint=20is=20required")=20=E2=80=94=20prepar?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Uploading to a Backblaze B2 (or any generic-S3) bucket failed with "S3 endpoint is
required." even though the connection tested fine.

Root cause: the two upload services have different prepareUpload contracts —
r2Service.prepareUpload(npub, { credentials }) vs s3UploadService.prepareUpload(settings).
MediaUploader calls both the r2 way, so for S3/B2 the npub STRING became the settings →
validateS3Connection saw no endpoint. Compounding it, a storageService.getConnection()
result keeps bucket/endpoint/region under `.meta`, which validateS3Connection reads at
the top level. (R2 worked because its service already uses the (npub, {credentials})
contract.)

Fix:
- s3UploadService.prepareUpload now accepts (npub, { credentials }) AND a direct settings
  object (back-compat), flattening meta → top-level via flattenS3Settings.
- The storage Test now derives/passes the B2 public URL (else the prefix), so it stops
  falsely warning "Public Bucket URL is missing. Uploads will fail."

Tests: tests/services/s3-upload-prepare-contract.test.mjs (3 — meta flatten, npub ignored
when credentials given, direct-settings back-compat). Build + lint clean; upload/storage
suites 46/46.
