Subject: [PATCH 01/27] uploads: locked-storage file picks unlock inline
 instead of dead-ending (#56)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All three paths (upload video pick, upload thumbnail pick, edit "Replace
file") now route through the shared signer gate — silent kept-unlocked
restore, else ONE passphrase prompt — then unlock storage and continue the
same pick. Cancel/bad-passphrase abort quietly; a refused thumbnail pick
restores the picker. Unlock glue extracted to uploadModalStorageUnlock.js
(file-size budget); ensureSigner threaded via initUploadModal/initEditModal.

Tests: tests/upload-edit-storage-unlock-gate.test.mjs (12).

Subject: [PATCH 02/27] publish: all-timeout content publishes are unconfirmed
 soft successes (#49)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

signAndPublishEvent (video publish/edit/repost/mirror), rebroadcastEvent, and
revertVideo now use assertAnyRelayAcceptedOrUnconfirmed: when every relay
times out without rejecting, the event was sent and almost always persisted,
so it no longer surfaces as "Failed to share video". Explicit rejections
still throw.

Messaging stays honest at every consumer:
- relay tally carries `unconfirmed` (now attached on edits too);
  describePublishOutcome maps 0-accepted+unconfirmed to a WARNING ("sent,
  no relay confirmed yet") — never a fake relay count, never a hard error
- edit/revert controllers say "sent, not confirmed yet" when unconfirmed
- deletes stay CONSERVATIVE: "deleted successfully" only when >=1 relay
  ACKed a tombstone or kind-5 (anyRelayAcceptedInSummaries); an unconfirmed
  revert no longer aborts deleteAllVersions midway, so the kind-5 always runs

Tests: tests/relay-ack-unconfirmed-content.test.mjs (6).

Subject: [PATCH 03/27] tests: spec-correct four stale tests hidden by piped
 exit codes

A per-file sweep (local suite runs were reading the PIPE's exit code, not
npm's) surfaced four tests failing on HEAD:

- hash-change-handler: logged-out default is deliberately TRENDING since
  04621efc; test still expected most-recent-videos
- session-actor / sessionActor / nsec-login: encoded the pre-fix "no-arg
  clearStoredSessionActor wipes EVERY account" behavior that 2026-07-02
  deliberately removed (one account's logout must not destroy other saved
  accounts' keys). Replaced with stronger assertions: multi-account survival
  on no-arg clear, targeted forget, and the blocked-key security property
  asserted on the blocked account specifically.

Integrity notes in each file; TODO #11b addendum documents the pipe lesson.

-      `describePublishOutcome` (the "shared to N relays" / warning UI). Applying
-      `assertAnyRelayAcceptedOrUnconfirmed` here must keep that outcome honest (an
-      unconfirmed publish should read as "shared, couldn't confirm" — NOT a hard
-      failure and NOT a false "shared to N relays"). Needs its own careful pass +
-      tests around the video outcome-describer and delete semantics (a false
-      "deleted" is worse than a false "publish failed").
-- [ ] Deletions (kind 5) especially: decide whether an unconfirmed delete should
-      report success optimistically or stay conservative.
+### 49. Relay-ack false-negatives on the generic content-publish path (HIGH-STAKES)
+> Same bug class as the list-publish fix (commit 47f2a9a8): all-timeout ≠ rejection.
+- [x] **DONE 2026-07-03 — generic content publish is unconfirmed-tolerant, with
+      HONEST outcome messaging at every consumer.** The three bare
+      `assertAnyRelayAccepted` call sites now use
+      `assertAnyRelayAcceptedOrUnconfirmed` (all-timeout → `summary.unconfirmed`,
+      soft success; explicit rejections STILL throw `RelayPublishError`):
+        - `signAndPublishEvent` (js/nostr/publishHelpers.js — video publish, edit,
+          repost, mirror, videoPublisher) + `rebroadcastEvent`.
+        - `revertVideo` (js/nostr/client.js) — so a slow-ack tombstone no longer
+          aborts `deleteAllVersions` midway (kind-5 hard delete now always runs).
+      Honesty plumbing (the reason this was deferred):
+        - The relay tally (`attachRelayPublishSummary`, now also attached on EDIT)
+          carries `unconfirmed`; `describePublishOutcome` maps accepted=0 +
+          unconfirmed → WARNING "sent, but no relay has confirmed receiving it
+          yet" — never a fake "published to N relays", never a hard failure.
+          Zero-accepted WITHOUT the flag stays the hard error.
+        - Edit: editModalController reads the tally and says "update sent, not
+          confirmed yet" instead of "updated successfully" when unconfirmed.
+        - Revert: revertModalController tracks per-entry summaries and only says
+          "Reverted…" when a relay ACKed; otherwise "sent, not confirmed yet".
+- [x] **Delete semantics — decided CONSERVATIVE.** A false "deleted" is worse
+      than a false "failed": `anyRelayAcceptedInSummaries` (js/nostrPublish.js)
+      scans every tombstone + kind-5 summary; `handleDeleteModalConfirm` only
+      claims "All versions deleted successfully!" when ≥1 relay ACKed something,
+      else "Delete request sent, but no relay has confirmed it yet — the video
+      may reappear until relays catch up." (Empty set = nothing to publish =
+      confirmed.) Tests: `tests/relay-ack-unconfirmed-content.test.mjs` (6, incl.
+      end-to-end signAndPublishEvent all-timeout vs rejection). Lint + build green.
+- [ ] **VERIFY on unstable:** with a slow/unreachable relay set, publish + edit +
+      delete a test video — messages should read "sent/unconfirmed", never
+      "failed", and the content should be correct after a refresh.

Subject: [PATCH 04/27] nostr: dev-gated REQ tracer at the pool.sub choke point
 (#9)

The cold-login REQ storm's remaining emitters are unpinned (the suspected
per-contact list loops don't exist; mutes are already batched). Every
sub/list flows through the shimmed pool.sub, so recordReq() there aggregates
kinds + relay fan-out + emitting call site per 10s window. Zero-cost when
off; arm with localStorage bitvid:reqTrace=1 (auto in dev mode), read
[req-trace] logs or window.__bitvidReqTrace.report().

One traced cold login on unstable will name the storm's sources; the
batching/deferral pass follows from that data.

Tests: tests/req-telemetry.test.mjs (3).

 ### 10. WebTorrent `null.fill` seeding crash
 - [ ] Investigate the vendored `webtorrent.min.js` `null.fill` error on wire handshake;
       may require a bundle update or patch.
+- [x] **Bounded investigation DONE 2026-07-03.** The vendored bundle is
+      webtorrent **2.5.11** (~2 years old; upstream latest is **3.0.16**). The
+      bundle has exactly two `.fill(` sites: a piece-bitfield fill and
+      `this.buffer.fill(void 0)` — fast-fifo's `clear()`, the queue streamx
+      uses under bittorrent-protocol's wire Duplex. "null.fill on wire
+      handshake" = that queue being touched after stream teardown (use-after-
+      destroy in the streamx/fast-fifo layer). No matching public upstream
+      issue found, but webtorrent 3.x now PINS `streamx` to an exact version
+      (2.25.0) — consistent with upstream having chased this bug class.
+- [ ] **Fix path: vendored-bundle update to 3.0.16 as its OWN task** (playback-
+      critical → own branch/soak, NOT bundled with other work): rebuild
+      `js/webtorrent.min.js` + `.map`, re-test URL+magnet playback, seeding,
+      the beacon app (`torrent/`), and the SW streaming path; rollback = keep
+      the old bundle file. Check 2.x→3.x breaking changes against
+      `js/webtorrent.js` usage first. Without a repro for the crash, a blind
+      local patch is guesswork — the update is the honest fix.
 
 ### 11. Harden flaky tests (CI gate reliability)
 - [ ] `tests/ui/uploadModal-reset.test.mjs` ("UploadModal Reset Logic") intermittently

Subject: [PATCH 06/27] profile modal: always-visible "Acting as" identity card
 (#43)

Identity pill top-center on every pane, straddling the header divider, so
users always see which profile they're acting as (e.g. before uploading).
Populated in renderSavedProfiles (same resolveMeta path as the Account pane
card, so it refreshes on profile switch), hidden when logged out, and
click-through jumps to the Account pane.

Subject: [PATCH 07/27] upload: in-modal "Upload destination" storage picker
 (#44)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The storage summary gains a connection <select> (hidden with fewer than two
connections) listing every configured connection with the default labelled.
Selection is a per-modal override — loadFromStorage re-resolves the summary
and credentials immediately, stale selections fall back to the default, and
the account default stays untouched. Picker logic lives in
uploadModalStorageUnlock.js for UploadModal's file-size budget.

Subject: [PATCH 08/27] feeds: "Most Zapped" sidebar tab ranked by zap totals
 (#47)

Trending-pattern clone ranked by sats from kind-9735 receipts:

- js/zapTotals.js: per-pointer receipt aggregation. The feed's metric getter
  returns the cached total and schedules a batched fetch (#a/#e chunks via
  the L1 SubscriptionManager) for unknown/stale pointers; amounts parse via
  nip57 bolt11 with the zap request's amount tag as fallback; receipts are
  deduped by id so re-fetches never double-count; zero-receipt answers are
  cached (2-min TTL).
- sorters.js: shared count-ranked sorter (metric desc, recency tie-break,
  author spread, trusted-muted sink); Trending delegates unchanged, Most
  Zapped ranks on runtime.getZapTotal.
- Full wiring: feed definition, view + info popover, change-signal re-rank
  (order settles as receipts stream in), sidebar link, viewManager registry,
  feedCoordinator case/loader, FEED_TYPES.MOST_ZAPPED, and a
  FEATURE_MOST_ZAPPED_FEED flag (default on; off hides the tab).

 ### 47. "Most Zapped" sidebar tab (trending-by-zaps)
-- [ ] Add a **Most Zapped** sidebar tab: like Trending (#27, view-count) but ranked by
-      **total zaps** (sats / zap count) per video. Reuse the zap accounting (kind-9735
-      receipts) already used for the zap system; build a feed source/ranker that sorts by
-      zap total over a window, wired into the feed engine like Trending. Depends on
-      reliable zap data (couples with the zap system already shipped in #3).
+- [x] **DONE 2026-07-03.** Full Trending-pattern clone ranked by SATS:
+        - `js/zapTotals.js` — per-pointer kind-9735 aggregation. The feed's
+          getZapTotal reads the cached total AND schedules a BATCHED one-shot
+          receipt fetch (`#a`/`#e` chunks via the L1 SubscriptionManager — the
+          direct-pool lint gate applies) for unknown/stale pointers (2-min TTL;
+          zero-receipt answers cached too). Amounts: nip57 bolt11 parse, falling
+          back to the zap request's amount tag (msats); receipts deduped by id
+          so re-fetches never double-count.
+        - Feed: `js/feedEngine/mostZappedFeed.js` + `createMostZappedSorter`
+          (sorters.js refactored to a shared count-ranked sorter — Trending
+          behavior unchanged: sats/views desc, recency tie-break, author
+          spread, trusted-muted sink).
+        - View: `views/most-zapped.html` + `js/mostZappedView.js` (re-runs the
+          feed on zapTotals' change signal, same settle-in pattern), sidebar
+          link, viewManager registry, feedCoordinator case/loader,
+          `FEED_TYPES.MOST_ZAPPED`, `FEATURE_MOST_ZAPPED_FEED` flag (default
+          on; off hides the tab like Trending's flag).
+      Tests: `tests/zap-totals.test.mjs` (5). Lint + build green.
+- [ ] **VERIFY on unstable:** open Most Zapped → zapped videos rise as receipts
+      load (unzapped feed reads as Recent at first); zap a video → within ~2min
+      of tab re-entry its rank reflects the new total.

Subject: [PATCH 09/27] cards: orange right-aligned zap-total badge next to
 view counts (#47 follow-up)

Video cards show the total sats from the shared zapTotals cache: new
--color-zap token (bitcoin orange, both themes), badge pushed to the
engagement row's end so views/comments stay left-aligned, hidden until a
nonzero total is known. The list view's zap binder fills [data-zap-total]
on bind (also scheduling the batched receipt fetch) and one shared change
listener updates every bound card as receipt batches land.

Subject: [PATCH 10/27] sync/zaps: enabled devices auto-pull newer
 wallet/storage notes at login; zap errors name the failing address (#15
 follow-up)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two fixes from live testing:

- "NWC doesn't sync unless I click Restore": devices with sync ENABLED only
  ever pushed-on-save — edits from another device sat unseen until the
  manual Restore click. encryptedSyncItem.autoPullIfNewer pulls the remote
  note at login when its created_at is newer than this device's last-synced
  marker (set on push AND now after a successful pull, so the same note is
  never re-pulled and the next conflict check stays honest). Wired into the
  login restore flow ahead of the one-time offer; disabled items are never
  touched.

- "Could not get user information" on a known-good creator address: that
  reason string comes from the LNURL SERVER, and the failing fetch was the
  PLATFORM-FEE address, not the creator's. prepareLightningContext now
  wraps both metadata fetches so the toast names which address failed
  (e.g. "Platform fee Lightning address (…): Could not get user
  information") instead of blaming the creator.

Subject: [PATCH 11/27] zaps: retry transient LNURL failures once before
 failing the zap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Verified live against strike.me: the SAME lnurlp endpoint returned
{status:"ERROR","reason":"Could not get user information"} on one request
and a valid callback moments later — the address was fine, the server
blipped. fetchPayServiceData now retries once (600ms) on the transient
classes (fetch rejection, non-OK HTTP, non-JSON body, ERROR-status body);
shape-invalid payloads still fail immediately, and a persistent error
surfaces the server's reason after the single retry.

Subject: [PATCH 12/27] zaps: fix badge never showing (array pointers) + zap
 total in the player modal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The zap-totals store's pointerKey only understood {type,value} objects, but
deriveVideoPointerInfo produces tag-style ARRAYS (["a", value, relay?]) — so
every card-badge lookup keyed to nothing, no receipt fetch was ever
scheduled, and the Most Zapped ranking metric silently read 0 for every
video. pointerKey now normalizes both shapes; tests use the array shape the
app actually passes.

Also adds the orange sats badge to the video player modal's meta row
(right side via the row's existing justify-between; views stay left),
driven by the same cache/change-signal as the cards and torn down with the
view-count subscription.

MIME-Version: 1.0

app.js delegates each feedCoordinator method explicitly (the coordinator is
lazy), and registerMostZappedFeed / loadMostZappedVideos were never added.
Bootstrap's `typeof app.registerMostZappedFeed === "function"` guard was
silently false (feed never registered) and the view registry's
loadMostZappedVideos call no-oped, so the view's spinner was never replaced.
Reproduced in a Playwright harness (spinner before, 158 videos rendered
after adding the delegates).

Also exposes window.__bitvidZapTotals (snapshot/request/flush) for
diagnosing zap-badge visibility in live sessions.

Root cause of "clicking a video card no longer opens the player":
coordinator methods run with `this` bound to the Application
(bindCoordinator), and the zap-badge helpers were added as coordinator
methods called via `this.subscribeModalZapTotal(...)` — but app.js only
exposes coordinator methods through explicit delegates, which were never
added. Every modal open threw "this.subscribeModalZapTotal is not a
function" inside subscribeModalViewCount (and every close threw in
teardown). Same delegate landmine that broke Most Zapped's loader.

The helpers are now plain closures inside createModalCoordinator — immune
to the delegate pattern by construction. Regression test drives the REAL
bindCoordinator with only app.js's actual delegates, so any future
cross-method `this.` call without a delegate fails in CI first.

Subject: [PATCH 15/27] zaps: make the card + modal zap counter always visible
 (0 sats when none)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Diagnosis (live, verified): the zap-totals pipeline is correct end to end —
a seeded receipt queries and sums to the right sats — but of 310 kind-9735
receipts reachable on the relays, ZERO reference any bitvid video, so every
badge was legitimately hidden. That reads as "broken" and profile zaps to a
Lightning address never attach to a video, so hidden-when-zero left the
feature invisible in practice.

Show the counter always, like the view counter it sits beside: "0 sats"
until a receipt lands, then the summed total. Card binder and modal render
no longer gate on sats>0; the badge is revealed on bind/open and re-hidden
on modal close (no video open). Live-checked: 158/158 cards render the
badge. Tests spec-corrected with integrity notes.

Subject: [PATCH 16/27] zaps: optimistic zap-total bump so the badge updates
 instantly on send
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors ingestLocalViewEvent for view counts: sending a zap through the
video modal now bumps that video's zap total immediately on the card + modal
badge, instead of waiting for the relay receipt (delayed by the 2-min cache
TTL, and dependent on the recipient's wallet actually publishing a 9735).

- zapTotals store tracks optimisticSats separately from real receipt sats;
  getSnapshot/request return the sum. When the real receipt for the pointer
  later arrives, runBatch clears the optimistic portion so it's never
  double-counted. If the receipt never lands (custodial wallets often don't
  publish), the bump persists in-memory until reload — keeping the zapper's
  own view honest.
- ZapController fires a new onZapSuccess({video, sats}) at the fully-success
  terminal point (sats = context.shares.total; both creator + platform shares
  tag the video, so the eventual relay total matches).
- ModalManager derives the pointer via app.deriveVideoPointerInfo (the SAME
  key the cards/modal subscribe with) and calls ingestLocalVideoZap.

Live-verified: a rendered card's badge went 0 sats -> 5K sats instantly on
ingest, no relay round-trip. Test covers the bump + replace-on-real-receipt.

Subject: [PATCH 17/27] zaps: durably persist sent zaps so they survive reload
 + rank on Most Zapped
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Root cause the user hit: NWC doesn't publish zap receipts, and neither does
bitvid — per NIP-57 the recipient's LNURL server publishes the kind-9735
receipt. Custodial providers (Strike) routinely don't, so a paid zap leaves
NO on-relay record to count, and the in-memory optimistic bump vanished on
reload → zapped videos showed 0 and never rose on Most Zapped.

Add a durable local ledger (localStorage bitvid:sentZaps:v1) of the user's
OWN sent zaps, seeded into the store's optimistic layer at construction so
the badge + Most-Zapped rank survive reloads with no receipt. Reconciliation:
when a real 9735 receipt for a pointer later appears on relays, the relay
becomes authoritative and that pointer's ledger entry is pruned, so a
receipt-publishing recipient never double-counts. ingestLocalZap writes the
ledger; runBatch prunes it.

Live-verified: card badge 0 -> 4.3K sats on send, still 4.3K after a full
page reload, ledger present in localStorage. Tests cover persist-across-
reload and prune-on-real-receipt.

Subject: [PATCH 18/27] docs: dev plan for bitvid-native, preimage-verified zap
 tally (#47)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Full spec for making Most Zapped + zap badges global/durable/cross-user
without depending on external wallets to publish NIP-57 receipts (which
custodial providers like Strike don't). Key insight: the payer holds the
preimage after NWC pay_invoice, and the invoice's description hash commits
to the zap request's pointer+amount — so a payer-signed event carrying
{zapRequest, bolt11, preimage} is verifiable with the same cryptographic
strength as a recipient-signed 9735, reusing bitvid's existing bolt11 decode
in zapReceiptValidator.js.

docs/zap-tally-plan.md covers: the event schema, the verify algorithm,
cross-source dedup by payment_hash (9735-preferred), file-by-file code
changes, security/edge cases, a feature-flagged rollout, a test plan, open
decisions, and an ordered task checklist so the build stays neat across
sessions. TODO #47 points at it. No code changes yet.

+# bitvid-native zap tally — dev plan
+
+> Status: **PLANNED (not started)** · Author: agent handoff · Created 2026-07-04
+> Scope: a bitvid-published, preimage-verified zap event so "Most Zapped" and the
+> per-card / per-modal zap totals are global, durable, and independent of whether
+> the recipient's Lightning provider publishes NIP-57 receipts.
+
+This document is the single source of truth for the change so work stays neat
+across sessions. Read it top to bottom before touching code; the **Task
+checklist** at the end is the ordered work queue.
+
+---
+
+## 1. Problem & context
+
+Zap totals today come from **NIP-57 zap receipts (kind 9735)**, which are
+published by the **recipient's LNURL / Lightning-address server** — not by
+bitvid, not by NWC, not by the sender's wallet. Custodial providers (Strike,
+the current `PLATFORM_LUD16_OVERRIDE`) routinely **do not publish** them. So a
+paid zap can leave **no on-relay record at all**, and:
+
+- per-card / modal zap badges show `0 sats` for videos that were really zapped,
+- "Most Zapped" ranks by recency because the metric is empty,
+- there is no global/cross-user tally to display.
+
+### What already exists (as of commit `cbc62306`)
+
+The zap-totals store (`js/zapTotals.js`) already layers three concerns; this
+plan **adds a fourth source** and leaves the rest intact:
+
+1. **Real 9735 receipts** — fetched + summed from relays, deduped by event id
+   (`runBatch`). Gold standard when they exist. **Keep.**
+2. **Session optimistic bump** — `ingestLocalZap`, shown instantly on send,
+   cleared when a real receipt for the pointer later arrives. **Keep.**
+3. **Durable local ledger** — `localStorage: bitvid:sentZaps:v1`, seeds the
+   optimistic layer at construction so the sender's own zaps survive reload.
+   Sender-only, per-device, not global. **Keep** (becomes the offline/instant
+   overlay).
+4. **NEW: bitvid-native zap tally event** — this plan. Global, durable,
+   cross-user, cryptographically verifiable, wallet-independent.
+
+### The insight that makes this sound (not a hack)
+
+A NIP-57 receipt is trusted because the recipient's server signs it — but the
+reason the *server* can attest is that it holds the **preimage** (proof the
+invoice settled). **The payer holds the same preimage** after an NWC
+`pay_invoice`. And the invoice's **description hash commits to the zap request**
+(`description_hash(bolt11) === sha256(zapRequestJSON)`), and the zap request
+contains the **video/profile pointer + amount**. So a payer-signed event
+carrying `{ zapRequest, bolt11, preimage }` is verifiable by *any* client with
+the same cryptographic strength as a 9735 receipt:
+
+1. `sha256(preimage) === payment_hash(bolt11)` → the invoice was actually paid.
+2. `description_hash(bolt11) === sha256(zapRequestJSON)` → that payment was for
+   *this* zap request (binds it to the pointer + amount — replay-proof: a stolen
+   preimage cannot be reused for a different video).
+
+bitvid **already implements both halves** of the bolt11 decode in
+`js/payments/zapReceiptValidator.js` (`extractDescriptionHashFromBolt11`, bech32
+tagged-field walker) — we extend it to also pull `payment_hash` and add one
+sha256 check. No new crypto dependency.
+
+---
+
+## 2. Goals & non-goals
+
+**Goals**
+- A zap the user sends through bitvid produces a **published, verifiable** event
+  so **other bitvid users** see it and it ranks on Most Zapped.
+- Survives reload / new device (it's on relays).
+- Works for **video zaps and profile zaps**.
+- Anti-spam by construction (must actually pay to inflate; misattribution
+  blocked by the description-hash binding).
+- Never double-counts against a real 9735 receipt for the same payment.
+
+**Non-goals**
+- Interop with other Nostr clients' zap UIs. bitvid **cannot** mint a valid
+  NIP-57 9735 (that must be signed by the recipient's server), so this event is
+  **bitvid-specific**; other clients ignore it. We still *count* real 9735s
+  wherever they exist, so bitvid stays a good NIP-57 citizen on the read side.
+- Replacing the local ledger or the 9735 path — this is an **additional** source.
+- Server-side aggregation. bitvid is a static client; counting stays client-side
+  (same as view counts).
+
+---
+
+## 3. The new event
+
+A **regular, non-replaceable** event (one per successful zap share; they sum),
+signed by the **payer's active signer** (the logged-in user). Modeled on how the
+kind-9735 receipt is shaped so our existing validator logic transfers.
+
+```
+kind:    ZAP_TALLY_KIND            // see Open decision D1 (proposed 9736)
+pubkey:  <payer pubkey>            // the sender's active signer
+created_at: <now>
+content: ""                        // (optional: mirror the zap comment)
+tags:
+  ["p", <recipientPubkey>]                       // zapped party
+  ["e", <videoEventId>]        (video zaps)       // from the zap request
+  ["a", "30078:<pubkey>:<dTag>"] (video zaps)     // stable coordinate
+  ["amount", "<msats>"]                           // echoes the zap request
+  ["bolt11", "<invoice>"]                          // carries payment_hash + description_hash
+  ["preimage", "<preimage>"]                       // proof of settlement
+  ["description", <zapRequestJSON>]                // the signed 9734 (NIP-57 shape)
+  ["client", "bitvid"]                             // provenance marker
+  ["t", "zap"]
+```
+
+- For **profile-only** zaps there is no `e`/`a`; the `p` tag is the pointer.
+- `description`, `bolt11`, `preimage`, `amount` are **exactly** what a 9735 would
+  carry, so verification reuses the 9735 validator almost verbatim.
+- The event is **self-verifying**: no need to trust the `amount` tag — the
+  authoritative amount is derived from the bolt11 (as the 9735 path already does
+  via `nip57.getSatoshisAmountFromBolt11`).
+
+### Verification algorithm (a valid tally event)
+1. `kind === ZAP_TALLY_KIND` and has a `bolt11` + `preimage` tag.
+2. `sha256(hexToBytes(preimage)) === payment_hash` extracted from the bolt11.
+3. `description_hash` from the bolt11 `=== sha256(utf8(description tag JSON))`.
+   *(NIP-57's own check — already the spine of `zapReceiptValidator`.)*
+4. Sats = `getSatoshisAmountFromBolt11(bolt11)` (authoritative, not the tag).
+5. Pointer keys = the `a`/`e` (and `p`) tags **from the embedded zap request**,
+   not the outer event's tags (defense against a mangled wrapper).
+
+Steps 2–3 are the anti-spam core. A faker must pay a real invoice, and cannot
+retarget a stolen preimage to a different video (the description hash binds it).
+
+---
+
+## 4. Counting, dedup & reconciliation
+
+The store gains a **fourth input** folded into the same `totals` map. The
+critical new concern is **cross-source dedup by `payment_hash`** so a single
+payment that produces *both* a 9735 receipt *and* a bitvid tally is counted once.
+
+Per-pointer entry becomes:
+```
+{
+  sats,                 // real receipts (9735) + verified tallies, deduped
+  optimisticSats,       // durable ledger + session bumps (unchanged)
+  receiptIds: Set,      // dedup by EVENT id (unchanged, for 9735)
+  paymentHashes: Set,   // NEW: dedup across sources by payment_hash
+  fetchedAt,
+}
+```
+
+Folding rules in `runBatch` (which now queries **both** kinds — see §5):
+- **9735 receipt**: if its `payment_hash` (from its bolt11) is already in
+  `paymentHashes` for the pointer → skip; else add sats, record event id +
+  payment_hash. 9735 is **preferred**: if a tally with the same payment_hash was
+  already counted, the 9735 replaces it (same sats — no delta — but marks the
+  payment as recipient-attested).
+- **bitvid tally**: run the §3 verification. If it fails → ignore. If its
+  `payment_hash` is already counted (by a 9735 or an earlier tally) → skip. Else
+  add the bolt11-derived sats, record payment_hash.
+- **optimistic/ledger prune** (existing behavior, generalized): when a pointer
+  gains *any* real counted zap (9735 **or** verified tally) whose payment_hash
+  matches nothing we optimistically bumped, we still clear the pointer's
+  `optimisticSats` + ledger entry, because the relay is now authoritative for it.
+  (Same "relay wins" rule already shipped; just triggered by tallies too.)
+
+Result: exactly-once counting per real payment, 9735-preferred, tally as the
+fallback, local ledger as the instant/offline overlay.
+
+---
+
+## 5. Code changes (file by file)
+
+### 5.1 `js/nostrEventSchemas.js` — new event type + builder
+- Add `NOTE_TYPES.ZAP_TALLY = "zapTally"` and a schema entry (kind
+  `ZAP_TALLY_KIND`, append-tags, content=text) next to `ZAP_REQUEST`.
+- Add `buildZapTallyEvent({ pubkey, created_at, recipientPubkey, eventId,
+  coordinate, amountMsats, bolt11, preimage, zapRequestJSON, comment })` mirroring
+  `buildZapRequestEvent` (§2270). Returns the unsigned event; caller signs.
+- Export the constant `ZAP_TALLY_KIND` (Open decision D1).
+
+### 5.2 `js/payments/zapReceiptValidator.js` — extract payment_hash + verify
+- Generalize the existing bolt11 tagged-field walker
+  (`extractDescriptionHashFromBolt11`, §164) into a helper that can also return
+  the **payment_hash** field (bolt11 tag `p`, 256-bit) — e.g.
+  `extractBolt11Fields(bolt11) -> { descriptionHash, paymentHash }`. Keep the old
+  function as a thin wrapper (no behavior change to the 9735 path).
+- Add `verifyPaymentPreimage(preimage, paymentHash)` = `sha256(hexToBytes(
+  preimage)) === paymentHash` (use `@noble/hashes/sha256` already pulled via
+  nostr-tools, or WebCrypto `subtle.digest`).
+- Add `verifyBitvidZapTally(event, { tools })` implementing §3 steps 1–5,
+  returning `{ ok, sats, pointerTags, paymentHash }`. Reuses the description-hash
+  check the 9735 validator already performs.
+
+### 5.3 `js/payments/zapSplit.js` — surface bolt11 + preimage on the receipt
+- The per-share `receipt` object (§481) already carries `invoice`, `payment`,
+  `zapRequest`, `amount`. Add the resolved **preimage** explicitly:
+  `receipt.preimage = payment?.result?.preimage || null` (the NWC `pay_invoice`
+  result is `payment.result` per `nwcClient.js` §1155; NIP-47 puts the preimage
+  there). No flow change — just expose it so the controller can publish a tally.
+- (bolt11 is already on `receipt.invoice.invoice`.)
+
+### 5.4 `js/ui/zapController.js` — publish tallies on success
+- The success terminal point already fires `this.callbacks.onZapSuccess({ video,
+  sats })` (added commit `af09505f`). **Extend the payload** to include the
+  per-share proof needed to build tallies:
+  `onZapSuccess({ video, sats, shares: receipts.map(r => ({ recipientType,
+  amountSats: r.amount, bolt11: r.invoice?.invoice, preimage: r.preimage,
+  zapRequest: r.zapRequest })) })`.
+- Only include shares whose `status === "success"` **and** have a `preimage`
+  (payment settled). Unvalidated-on-relay is fine — that's exactly the case this
+  feature exists for.
+- The **retry** path (`executeRetry`, §226) should fire the same hook for the
+  shares it settles (today it doesn't call onZapSuccess at all — wire it).
+
+### 5.5 `js/ui/ModalManager.js` — build, sign, publish, ingest
+- The `onZapSuccess` callback (added `af09505f`, currently just calls
+  `ingestLocalVideoZap`) becomes:
+  1. Keep the instant `ingestLocalVideoZap(pointer, sats)` (optimistic overlay).
+  2. For each successful share with a preimage, call a new
+     `app.publishZapTally({ video, share })` (thin app method) that:
+     - derives the pointer via `app.deriveVideoPointerInfo(video)` (same key the
+       badge uses),
+     - builds the tally via `buildZapTallyEvent(...)`,
+     - signs with the active signer (the user is logged in to have zapped),
+     - publishes via the existing relay-publish path
+       (`signAndPublishEvent` / `publishEventToRelays`, using
+       `assertAnyRelayAcceptedOrUnconfirmed` — an all-timeout publish is a soft
+       success like #49),
+     - on success, `store.ingestVerifiedZap(pointer, sats, paymentHash)` so the
+       local view is authoritative immediately (and the durable ledger entry can
+       be upgraded/cleared — see §4).
+- Publishing is **best-effort and non-blocking**: a failed tally publish must not
+  affect the payment UX (the sats already moved). Log + rely on the local ledger.
+
+### 5.6 `js/zapTotals.js` — count tallies as a fourth source
+- `runBatch`: add a second filter set querying `kinds: [ZAP_TALLY_KIND]` by the
+  same `#a`/`#e` pointer batches (and `#p` for profile pointers — see Open
+  decision D2). One `manager.list` call can carry both kinds' filters.
+- Fold results per §4: verify each tally (`verifyBitvidZapTally`), dedup by
+  `payment_hash`, prefer 9735.
+- Add `paymentHashes` to entries; thread it through the existing dedup.
+- Add `ingestVerifiedZap(pointer, sats, paymentHash)` — like `ingestLocalZap`
+  but records the payment_hash and writes to `sats` (authoritative) rather than
+  `optimisticSats`, so the sender's own tally isn't re-counted when it comes back
+  from the relay (dedup by payment_hash handles the echo).
+- Expose `verifyBitvidZapTally` injection point for tests (mirror `getTools`).
+
+### 5.7 `js/constants.js` — feature flag
+- Add `FEATURE_ZAP_TALLY` (default **off** for the first ship; flip on after a
+  soak). Gate both **publishing** (5.5) and **counting** (5.6) behind it so it's
+  a clean rollback and so a half-rolled-out network doesn't miscount.
+
+### 5.8 Profile zaps (optional, same primitives)
+- Channel/profile zap surfaces that call the zap flow pass a `p`-only pointer;
+  the store keys by `p:<pubkey>`. The card/modal badges are video-scoped today,
+  so a profile zap total would surface on channel pages — a follow-up UI task,
+  not required for the video path. Track as D2.
+
+---
+
+## 6. Data flow (end to end)
+
+```
+User clicks Zap (video modal)
+  → zapController.sendZap → runZapAttempt → app.splitAndZap (zapSplit)
+      → per share: build 9734 zap request → LNURL callback → invoice
+      → NWC pay_invoice → payment.result.preimage
+      → receipt { amount, invoice.invoice(bolt11), preimage, zapRequest, status }
+  → success terminal:
+      onZapSuccess({ video, sats, shares:[{amountSats,bolt11,preimage,zapRequest}] })
+        → ingestLocalVideoZap(pointer, sats)          // instant + durable ledger
+        → for each settled share: app.publishZapTally  // build→sign→publish
+              → store.ingestVerifiedZap(pointer, sats, paymentHash)
+
+Any client later, on a grid/modal:
+  store.request(pointer) → runBatch queries kinds [9735, ZAP_TALLY_KIND] by #a/#e
+    → 9735: sum (dedup by event id + payment_hash)
+    → tally: verifyBitvidZapTally → sum (dedup by payment_hash, 9735-preferred)
+  → badge + Most-Zapped metric reflect the global, verified total
+```
+
+---
+
+## 7. Security & edge cases
+
+- **Fake inflation** — blocked: must pay a real invoice (preimage check), and the
+  sats are bolt11-derived, not tag-claimed. Inflation costs the attacker real
+  sats.
+- **Preimage replay to another video** — blocked: `description_hash(bolt11)`
+  commits to the zap request, which contains the pointer; a retargeted event
+  fails step 3.
+- **Duplicate publish / relay echo** — dedup by `payment_hash` across all
+  sources; the sender's own tally coming back from a relay is a no-op.
+- **Self-zapping** — possible but only adds sats the attacker actually spent;
+  economically pointless. WoT/moderation already available if we later want to
+  weight or hide (mirror the view-count treatment).
+- **Amount mismatch** — ignore the `amount` tag; always use the bolt11 amount.
+- **Missing preimage** (wallet returns none) — skip the tally, fall back to the
+  local ledger; the sender still sees their zap, it just isn't globally attested.
+- **REQ load** — one extra kind in the existing batched receipt fetch (no new
+  round trip); one publish per zap share (small, non-blocking).
+- **Privacy** — a tally publicly links the payer pubkey → video + amount. This is
+  the same disclosure as a NIP-57 zap (zaps are public by design), but note it in
+  the UI copy. The feature flag lets us default-off until we're comfortable.
+
+---
+
+## 8. Testing plan
+
+Unit (node:test, deterministic, no network):
+- `zap-tally-verify.test.mjs` — `verifyBitvidZapTally`: valid passes; bad preimage
+  fails (step 2); mismatched description hash fails (step 3, replay); amount taken
+  from bolt11 not the tag. Use fixed bolt11/preimage vectors.
+- `zap-tally-schema.test.mjs` — `buildZapTallyEvent` emits the exact tag set for
+  video vs profile pointers.
+- Extend `zap-totals.test.mjs` — cross-source dedup: a 9735 and a tally with the
+  same payment_hash count once; a tally with a new payment_hash adds; an invalid
+  tally is ignored; 9735-preferred.
+- `zap-controller` / `ModalManager` wiring — onZapSuccess forwards per-share
+  proof; publishZapTally is best-effort (a publish throw doesn't break the success
+  path); flag-off short-circuits publish + count.
+
+Live (Playwright harness, mock relay — pattern from this session's diagnostics):
+- Seed a verified tally event → it counts + ranks; seed an invalid one → ignored.
+- End-to-end with a stubbed wallet returning a known preimage → publish → re-fetch
+  → badge reflects it after a simulated reload.
+
+Gates: `npm run lint`, `npm run build`, targeted suites. New tests carry
+`test_integrity_note` blocks (Dark Factory rules).
+
+---
+
+## 9. Rollout
+
+1. Land behind `FEATURE_ZAP_TALLY = false` on `unstable`; verify counting logic
+   with seeded events (no publishing yet in the wild).
+2. Flip publishing on for `unstable`, dogfood real zaps, confirm cross-user
+   visibility on a second browser.
+3. Soak on `beta`; watch for miscounts / dedup gaps.
+4. Default-on to `main` once the payment_hash dedup is proven against real 9735s.
+
+Rollback: flip the flag off (stops publishing + counting); already-published
+tallies simply stop being counted. No data migration.
+
+---
+
+## 10. Open decisions (need a call before/at build time)
+
+- **D1 — event kind.** Proposed `9736` (adjacent to the 9735 receipt, "bitvid zap
+  tally"). Must confirm it's unassigned in the NIP kind registry; if risky, pick a
+  clearly app-specific regular kind and reserve it in `docs/nostr-event-schemas.md`.
+  Everything references `ZAP_TALLY_KIND` so the number is a one-line change.
+- **D2 — profile zaps in v1?** Video path is the ask; profile path is the same
+  primitives + a channel-page badge. Ship video-only first, profile as a
+  follow-up? (Recommended: yes, video-only v1.)
+- **D3 — publish relays.** Publish the tally to the user's write relays (same as
+  video publishing) so bitvid clients querying those relays see it. Confirm the
+  store queries a superset (it queries `client.relays`). Likely fine; verify.
+- **D4 — privacy default.** Default the feature flag off and add one line of UI
+  copy ("your zap will be publicly attributed on bitvid") before default-on?
+
+---
+
+## 11. Task checklist (ordered — pick up here across sessions)
+
+- [ ] **D1** decide `ZAP_TALLY_KIND`; add constant + `docs/nostr-event-schemas.md` row.
+- [ ] `constants.js`: `FEATURE_ZAP_TALLY` (default off) + runtime-flag plumbing.
+- [ ] `nostrEventSchemas.js`: `NOTE_TYPES.ZAP_TALLY` schema + `buildZapTallyEvent`.
+- [ ] `zapReceiptValidator.js`: `extractBolt11Fields` (payment_hash),
+      `verifyPaymentPreimage`, `verifyBitvidZapTally`. Unit tests first (vectors).
+- [ ] `zapSplit.js`: expose `receipt.preimage`.
+- [ ] `zapController.js`: extend `onZapSuccess` payload with per-share proof; wire
+      the retry path.
+- [ ] `ModalManager.js` + a thin `app.publishZapTally`: build→sign→publish
+      (best-effort, flag-gated) → `store.ingestVerifiedZap`.
+- [ ] `zapTotals.js`: query `ZAP_TALLY_KIND`, verify + dedup by payment_hash
+      (`paymentHashes` set), `ingestVerifiedZap`, flag-gate counting.
+- [ ] Tests: verify, schema, cross-source dedup, wiring, flag-off; Playwright
+      seeded-event count/rank.
+- [ ] `lint` + `build` + suites green; push to `unstable`.
+- [ ] Rollout per §9; TODO entry updated.
+
+---
+
+## 12. Relationship to existing work (so nothing regresses)
+
+- `js/zapTotals.js` — extend, don't rewrite. The array/object `pointerKey` fix,
+  the always-visible badge, optimistic bump, durable ledger, and "relay wins"
+  prune all stay; the tally is a new counted source folded into the same map.
+- `js/app/modalCoordinator.js` / `js/ui/views/videoCardZapTotals.js` — **no
+  change**; they render `store.getSnapshot`, which now includes verified tallies.
+- `js/feedEngine/mostZappedFeed.js` — **no change**; its metric is
+  `requestVideoZapTotal`, which now reflects tallies.
+- The NIP-57 `zapReceiptValidator` 9735 path — untouched behavior; we only add
+  helpers and reuse its bolt11 decode.

Subject: [PATCH 19/27] docs: add dual-line popularity chart (views + zaps over
 time) to the zap plan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends docs/zap-tally-plan.md §5.9: a second orange zaps-over-time line on the
per-video Popularity chart beside the existing red views line, a legend
(red=Views / orange=Zaps sats), and VISIBLE date labels (the current chart only
puts the range in the SVG aria-label). Reuses the --color-zap token from the
badges, buckets cumulative sats from 9735 + verified tally events (deduped by
payment_hash, same rule as the store), and can partially ship on 9735-only data
before the tally event lands. Adds checklist items, a chart Y-axis open
decision (D5), test targets, and updates goals/scope + TODO #47.

+### 5.9 Popularity chart: second (orange) zaps line + legend + date axis
+
+The per-video **Popularity** modal (`js/viewCountChart.js`, opened from the ⋯
+menu — feature #26) currently plots ONE cumulative **views** series and, notably,
+puts the date range only in the SVG `aria-label` — there is **no visible legend
+and no visible date labels**. This sub-feature adds a second series and the
+missing chart furniture. It can ship in two stages: the chart plumbing works
+with today's on-relay zap data (real 9735 receipts) even before the tally event
+(§3) exists; tallies simply make the orange line populated for Strike-style zaps.
+
+**Current shape to build on**
+- `buildViewCountTimeSeries(events)` → `{ series:[{bucketStart, count,
+  cumulative}], total }`, bucketed per day (`VIEW_CHART_WINDOW_SECONDS`).
+- `buildViewCountChartSvg(doc, series, {width,height})` — one `<polyline>` +
+  area, colored by `svg.classList.add("text-accent")` + `stroke="currentColor"`
+  (this instance's `--color-accent` is red). `pad.bottom:18` already reserves
+  space for an axis strip that today draws nothing visible.
+- The modal (`openPopularityModal`) fetches view events
+  (`listVideoViewEventsWithDefaultClient` + `subscribe…`), dedupes by id, and
+  re-renders on a 250ms debounce.

+
+1. **Zap time-series data.** Add a `buildZapSatsTimeSeries(events, { tools })`
+   next to `buildViewCountTimeSeries`: bucket **cumulative SATS** per day from
+   the union of **9735 receipts** and **verified bitvid tallies** (§3), deduping
+   by **payment_hash** (reuse the store's rule so the chart and the badge agree).
+   Amount per event = `getSatoshisAmountFromBolt11` (authoritative), created_at =
+   the receipt/tally timestamp. Output shape mirrors the view series:
+   `{ series:[{bucketStart, sats, cumulative}], total }`.
+
+2. **Zap event source.** Add `listVideoZapEventsWithDefaultClient(pointer)` +
+   `subscribeVideoZapEvents…` (mirror the view-event facade) that list/subscribe
+   `kinds:[9735, ZAP_TALLY_KIND]` for the pointer's `#a`/`#e`. The modal fetches
+   BOTH streams (views + zaps) and re-renders on the same debounce. Reuse the
+   store's verify + payment_hash dedup helpers (§5.6) so there is one code path
+   for "what counts."
+
+3. **Dual-series renderer.** Generalize `buildViewCountChartSvg` into
+   `buildPopularityChartSvg(doc, { views, zaps }, opts)` that draws BOTH
+   cumulative lines on a shared **time** X axis, each with its **own Y scale**
+   (views in counts, zaps in sats are different units — independent per-series
+   scaling shows the trend/shape honestly without a misleading shared axis; a
+   dual labeled Y-axis is an option — see D5). Colors are token-based:
+   - views line/area → `text-accent` / `currentColor` (red) — unchanged.
+   - zaps line/area → the **`--color-zap`** orange token added for the badges.
+     The token lint forbids raw colors and `var()` in attributes, so add a
+     small utility class (e.g. `.text-zap { color: var(--color-zap); }` in
+     `css/tailwind.source.css`) and wrap the zap series in a `<g class="text-zap">`
+     using `stroke="currentColor"` — same pattern the views line already uses.
+   Draw the zap area at a low opacity like the views area so overlaps stay legible.
+
+4. **Legend.** Below/above the chart, a small two-item legend: a red swatch
+   "Views" and an orange swatch "Zaps (sats)". Plain DOM (`el(doc,…)` helper),
+   token colors via the `.text-accent` / `.text-zap` classes. Include it in the
+   modal so both series are labeled; keep it out of the tiny inline card sparkline
+   if one is ever added.
+
+5. **Visible date axis.** Draw X-axis tick labels (not just `aria-label`): at
+   minimum the first and last bucket dates, ideally 3–4 evenly spaced ticks, using
+   the existing `formatDay(seconds)` formatter, as `<text>` nodes in the reserved
+   `pad.bottom` strip (token text color, `text-2xs`). Add light vertical gridlines
+   at the ticks if it reads cleanly. This answers "users don't know what they're
+   looking at."
+
+6. **Headline + copy.** The modal headline stays the authoritative view count;
+   add a second line for the zap total (from `store.getSnapshot`, so it matches
+   the badge) — e.g. "1.2K views · 4.3K sats zapped". Update the footer note to
+   "Public view + zap data · updates as more load."
+
+**Empty/degenerate states** (mirror the view chart): no zaps → no orange line +
+a greyed "Zaps (sats)" legend item (or omit); a single zap bucket → flat baseline
+segment like the single-view case.
+
+**Independence:** this renders whatever zap events exist on relays. Before the
+tally event ships, the orange line reflects only real 9735s (often empty for
+Strike); after, it reflects tallies too. The local durable ledger (badge-only,
+no per-event timestamps) does **not** feed the time chart — another reason the
+published tally matters for a meaningful zaps-over-time line.

First slice of docs/zap-tally-plan.md (decisions D1-D5 resolved in the doc):

- ZAP_TALLY_KIND = 30081 (addressable, d=payment_hash → one canonical event
  per real payment) + NOTE_TYPES.ZAP_TALLY schema + buildZapTallyEvent
  (nostrEventSchemas.js). Video + profile pointers.
- FEATURE_ZAP_TALLY flag (constants.js), default ON per D4.
- zapReceiptValidator.js: extractBolt11Fields (payment_hash + description_hash
  from the existing bech32 walker), verifyPaymentPreimage
  (sha256(preimage)==payment_hash), verifyBitvidZapTally — the security core:
  proves the invoice was paid AND bound to this zap request (description-hash
  binding blocks reusing a leaked preimage for another video). Amount is
  bolt11-derived, never the tag; pointers come from the embedded zap request.
- Schema-doc row for kind 30081.

Tests: tests/zap-tally-verify.test.mjs (8) — preimage check, bech32 field
round-trip, valid/bad-preimage/replay/zero-sats decisions, builder tag shape
(video + profile). Lint + build green.

No publishing or counting wired yet — next slices per the plan checklist.

-## 10. Open decisions (need a call before/at build time)
+## 10. Decisions (RESOLVED 2026-07-04)
 
-- **D1 — event kind.** Proposed `9736` (adjacent to the 9735 receipt, "bitvid zap
-  tally"). Must confirm it's unassigned in the NIP kind registry; if risky, pick a
-  clearly app-specific regular kind and reserve it in `docs/nostr-event-schemas.md`.
-  Everything references `ZAP_TALLY_KIND` so the number is a one-line change.
-- **D2 — profile zaps in v1?** Video path is the ask; profile path is the same
-  primitives + a channel-page badge. Ship video-only first, profile as a
-  follow-up? (Recommended: yes, video-only v1.)
-- **D3 — publish relays.** Publish the tally to the user's write relays (same as
-  video publishing) so bitvid clients querying those relays see it. Confirm the
-  store queries a superset (it queries `client.relays`). Likely fine; verify.
-- **D4 — privacy default.** Default the feature flag off and add one line of UI
-  copy ("your zap will be publicly attributed on bitvid") before default-on?
-- **D5 — chart Y-axis (§5.9).** Independent per-series scaling (each cumulative
-  line filling the height — simplest, trend-focused, **recommended**) vs. a dual
-  labeled Y-axis (left=views, right=sats — more precise, busier in a small modal).
+- **D1 — event kind → ADDRESSABLE `ZAP_TALLY_KIND = 30081`, `d = payment_hash`.**
+  Chosen: a higher, app-specific kind in bitvid's own family (30078 video,
+  30079 view, **30081** zap tally). Addressable (30000–39999) with the
+  per-payment `payment_hash` as the `d` tag makes each real payment map to
+  exactly ONE canonical event — relay-level idempotency; a re-publish replaces
+  rather than duplicates. Still queried by its `#a`/`#e`/`#p` tags like a 9735.
+  Reserve the kind in `docs/nostr-event-schemas.md`.
+- **D2 — scope → VIDEO + PROFILE zaps in v1.** Video path drives the badges/Most
+  Zapped; profile path reuses the same primitives with a `p`-only pointer and a
+  channel-page total (new small UI surface). Both ship in v1.
+- **D3 — publish relays → user's WRITE relays** (same path as video publishing).
+  The store queries `client.relays` (a superset incl. write relays); verify at
+  wiring time.
+- **D4 — publishing → ON BY DEFAULT.** `FEATURE_ZAP_TALLY` still exists for
+  rollback but defaults **true**; every successful zap publishes a tally. Keep a
+  short one-line disclosure in the zap UI ("zaps are publicly attributed on
+  bitvid") since it's honest and cheap, but no opt-in gate.
+- **D5 — chart Y-axis → INDEPENDENT PER-SERIES scaling.** Each cumulative line
+  fills the height against its own max; the legend names the two units. No dual
+  labeled Y-axis.

Subject: [PATCH 21/27] zaps: count bitvid tallies in the zap-totals store
 (#47)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Second slice of docs/zap-tally-plan.md §4. runBatch now queries kinds
[9735, ZAP_TALLY_KIND] in one call and folds both sources:

- 9735 receipts: unchanged sum, but now also records each receipt's
  payment_hash (from its bolt11) for cross-source dedup.
- bitvid tallies: verifyBitvidZapTally (preimage + description-hash bound),
  amount from the bolt11, pointers from the embedded zap request; counted
  once per payment_hash so a payment that yields BOTH a 9735 and a tally is
  never double-counted.

Entries gain a paymentHashes set. Counting is gated by isTallyEnabled
(singleton reads FEATURE_ZAP_TALLY live). The existing "relay wins" prune
clears the optimistic/ledger overlay once a real tally or receipt lands, so
the sender's own published tally reconciles the instant bump with no extra
plumbing.

Tests: cross-source/same-payment dedup, invalid-tally rejection, flag gating
(tests/zap-totals.test.mjs). Lint + build green.

Subject: [PATCH 22/27] zaps: publish preimage-verified tallies on successful
 zap (#47)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Third slice of docs/zap-tally-plan.md §5.3-5.5 — the publish side:

- zapSplit.js: surface receipt.preimage (NWC pay_invoice result.preimage).
- zapController.js: onZapSuccess now forwards per-share proof
  {recipientType, amountSats, bolt11, preimage, zapRequest} for every settled
  share with a preimage.
- zapTallyPublisher.js (new): buildTallyFromShare (pure — builds the addressable
  tally from a share's bolt11/preimage/zap-request, d=payment_hash, pointers
  from the zap request) + publishZapTallies (best-effort, flag-gated, never
  throws).
- ModalManager.js: onZapSuccess keeps the instant optimistic bump AND publishes
  the tallies via nostrClient.signAndPublishEvent to write relays (an
  all-timeout publish is a soft success per #49). A publish failure is
  non-fatal — the durable local ledger still shows the sender their zap.

With the counting slice (025ab348), a sent zap now: shows instantly (ledger),
publishes a verified tally, and every bitvid client counts it — surviving the
recipient never publishing a 9735. Tests: tests/zap-tally-publisher.test.mjs
(5). Lint + build green.

Subject: [PATCH 23/27] zaps: end-to-end verify test + plan checklist status
 (#47)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds an integration test exercising the REAL verifier against a genuinely
valid, amount-bearing bolt11 (real bech32 decode + nip57 amount parse + real
preimage/description-hash math, no injected fields) — proves the tally pieces
compose. Marks the shipped slices in docs/zap-tally-plan.md §11 and lists the
remaining v1 work: profile-zap #p counting + channel-page UI, the retry-path
publish hook, and the popularity chart (§5.9).

 ## 11. Task checklist (ordered — pick up here across sessions)
 
-- [ ] **D1** decide `ZAP_TALLY_KIND`; add constant + `docs/nostr-event-schemas.md` row.
-- [ ] `constants.js`: `FEATURE_ZAP_TALLY` (default off) + runtime-flag plumbing.
-- [ ] `nostrEventSchemas.js`: `NOTE_TYPES.ZAP_TALLY` schema + `buildZapTallyEvent`.
-- [ ] `zapReceiptValidator.js`: `extractBolt11Fields` (payment_hash),
-      `verifyPaymentPreimage`, `verifyBitvidZapTally`. Unit tests first (vectors).
-- [ ] `zapSplit.js`: expose `receipt.preimage`.
-- [ ] `zapController.js`: extend `onZapSuccess` payload with per-share proof; wire
-      the retry path.
-- [ ] `ModalManager.js` + a thin `app.publishZapTally`: build→sign→publish
-      (best-effort, flag-gated) → `store.ingestVerifiedZap`.
-- [ ] `zapTotals.js`: query `ZAP_TALLY_KIND`, verify + dedup by payment_hash
-      (`paymentHashes` set), `ingestVerifiedZap`, flag-gate counting.
-- [ ] Tests: verify, schema, cross-source dedup, wiring, flag-off; Playwright
-      seeded-event count/rank.
-- [ ] `lint` + `build` + suites green; push to `unstable`.
-- [ ] Rollout per §9; TODO entry updated.
+- [x] **D1** `ZAP_TALLY_KIND = 30081` (addressable, d=payment_hash) + constant +
+      `docs/nostr-event-schemas.md` row. (commit a6b2996f)
+- [x] `constants.js`: `FEATURE_ZAP_TALLY` (default ON per D4) + runtime plumbing.
+- [x] `nostrEventSchemas.js`: `NOTE_TYPES.ZAP_TALLY` schema + `buildZapTallyEvent`.
+- [x] `zapReceiptValidator.js`: `extractBolt11Fields`, `verifyPaymentPreimage`,

+- [x] `zapSplit.js`: expose `receipt.preimage`. (commit 41e533e6)
+- [x] `zapController.js`: `onZapSuccess` forwards per-share proof.
+      *(Retry path still TODO — see below.)*
+- [x] `zapTallyPublisher.js` (buildTallyFromShare + publishZapTallies) +
+      `ModalManager.js` wiring: build→sign→publish (best-effort, flag-gated).
+      No `ingestVerifiedZap` needed — the store's existing "relay wins" prune
+      reconciles the optimistic ledger when the published tally is fetched back.
+- [x] `zapTotals.js`: query `[9735, ZAP_TALLY_KIND]`, verify + dedup by
+      payment_hash (`paymentHashes` set), flag-gated counting. (commit 025ab348)
+- [x] Tests: verify, schema, publisher, cross-source dedup, flag-off, e2e verify.
+- [x] `lint` + `build` + suites green; pushed to `unstable`.
+- [ ] **Remaining v1 work:**
+      - [ ] **Profile-zap counting:** the store queries `#a`/`#e` only — add
+            `#p` batches so a profile-only tally (no video pointer) is fetched,
+            and a channel-page total UI surface (D2 chose video+profile).
+      - [ ] **Retry path:** `zapController.executeRetry` doesn't fire
+            `onZapSuccess`; wire it so retried shares also publish tallies.
+      - [ ] **Popularity chart §5.9:** orange zaps line + legend + date axis.
+      - [ ] Live end-to-end on unstable (real zap → tally on relay → second
+            browser counts it); rollout per §9.
 
 **Popularity chart (§5.9 — can start once the store's verify + dedup helpers
 exist; the renderer/legend/axis parts have no dependency on publishing tallies):**

Subject: [PATCH 24/27] zaps: retried shares also publish tallies + bump the
 badge (#47)

executeRetry now fires the same onZapSuccess hook as the main send path with
the retried shares' proof, so a zap completed via the retry flow gets its
optimistic bump and preimage-verified tally publish too (was previously only
on the first-attempt path). Closes the retry-path item in the plan checklist.

Subject: [PATCH 26/27] zaps: reliable coinos platform address + fix NWC
 double-pay on timeout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two things:

1. Platform fee address → a4a6b5849bc917b3befd5c81@coinos.io (verified live:
   allowsNostr + nostrPubkey, 1-sat min, working callback). coinos is
   Nostr-native and PUBLISHES zap receipts, unlike strike.me whose flaky LNURL
   + never-published receipts caused the platform-share pay timeouts and the
   missing zap tallies. The 30% platform fee is unchanged — only the rail.

2. Double-pay guard (bug found while diagnosing): on a `pay_invoice` timeout,
   nwcClient's nip44->nip04 encryption-fallback resent the request — but a
   timeout is ambiguous (the wallet may already be paying), so the resend
   could DOUBLE-SPEND. shouldRetryWithFallback now refuses to auto-resend any
   spending method (pay_invoice/pay_keysend/multi_pay_*) on timeout; read-only
   methods and explicit unsupported-encryption rejections (wallet never paid)
   stay retryable. The manual "Send again" retry is the safe path for a real
   payment timeout.

Tests: tests/nwc-pay-timeout-no-double-spend.test.mjs (4). Lint + build green.

Subject: [PATCH 27/27] playback: fix false "No playable source found." on
 URL-only videos
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A bitvid (kind-30078) video with a perfectly playable hosted URL (verified:
archive.org 200 video/mp4 with byte ranges) failed with "No playable source
found." — the video element's src was never even set.

Root cause: the hosted-URL probe (fetch HEAD, mode:no-cors) runs BEFORE src is
assigned, inside the playback-start window — but URL_PROBE_TIMEOUT_MS (4s) is
LONGER than PLAYBACK_START_TIMEOUT (3s). A slow no-cors HEAD (archive.org, and
any host that doesn't answer HEAD fast) consumed the whole start budget, the
withTimeout wrapper aborted the attempt, and the URL was never loaded. A
`<video>` element plays cross-origin URLs WITHOUT CORS anyway, so the fetch
probe was both unnecessary and actively harmful here.

Fix:
- Skip the probe entirely when there's no magnet (URL-only) — nothing to fail
  over to, so the video element loads the URL directly. This is the reported
  case; verified live: the video now plays (readyState 4, currentTime advancing).
- An ambiguous/error probe no longer VETOES the URL (only a definitively-read
  "bad" status deprioritizes it, and even then only when a magnet fallback
  exists) — the video element + watchdogs are the real arbiter.

Tests: spec-corrected the always-probe assertion to a dual-source case + added
a URL-only skip-probe test (tests/services/playbackService.test.mjs). 17 pass.
