Grant 7c4dfbacd2 WIP — port purchase/subscriptions/reconcile/upgrade/tipping to merchant-profile resolution (part 2)
Threads the merchant-profile + payment-provider snapshot semantics through
every call site that used to call state.payment_provider() (the legacy
"active provider" singleton). New invoices now record which provider
settled them; subscriptions snapshot both merchant_profile_id and
payment_provider_id at creation so mid-cycle product re-routing doesn't
redirect existing buyers; the reconciler picks the right provider per
invoice; tipping draws from the same Bitcoin balance that received the
purchase; tier-change invoices stick with the buyer's existing merchant
identity.

migrations/0021_invoice_provider_link.sql (new)
  Adds invoices.payment_provider_id (nullable FK), backfills existing
  pending/settled rows to the earliest-connected provider on the default
  profile. Additive — no drops, no removals. Companion to 0020 from the
  foundation commit.

models.rs
  Invoice gains payment_provider_id: Option<String>.

db/repo.rs
  row_to_invoice reads the new column. All three invoice SELECTs include
  it. create_invoice + create_invoice_with_currency take a new optional
  payment_provider_id parameter and persist it on INSERT.

subscriptions.rs
  Subscription struct gains merchant_profile_id + payment_provider_id
  (snapshotted on create). SUB_COLS + row_to_subscription + the manual
  SELECT in find_lapsing_subscriptions all updated. create_subscription
  accepts both new fields and writes them on the INSERT row.

  renew_one — reads the sub's payment_provider_id snapshot and resolves
  the provider via state.payment_provider_by_id(). Falls back to the
  legacy state.payment_provider() for any subs created pre-:52 that
  the migration backfill missed.

  capture_zaprite_payment_profile — uses the INVOICE's provider, not
  "the active one." Saved-profile ids are scoped per Zaprite org; using
  the wrong provider would fail the lookup.

  try_auto_charge_zaprite — uses the sub's snapshotted provider (same
  rationale).

reconcile.rs
  Per-invoice provider lookup. Each pending invoice is reconciled
  against state.payment_provider_by_id(inv.payment_provider_id), with
  graceful fallback for NULL provider ids. No more single-global-
  provider assumption.

tipping.rs
  Tip pay-out uses the provider that settled the license's purchase
  invoice (joined via licenses.invoice_id). Same rationale as the
  capture hook — the tip needs to draw from the right LN node.

api/upgrade.rs (both buyer-driven and admin-driven tier-change sites)
  Tier-change invoices ride on existing licenses. The right provider
  is whichever the license's subscription is snapshotted to (so the
  proration charge settles to the same merchant identity that collects
  renewal fees). Falls back to the invoice's recorded provider, then
  the legacy default, for licenses with no subscription or pre-
  snapshot rows.

api/purchase.rs
  StartPurchaseReq gains an optional `rail` field
  ("lightning"/"onchain"/"card") for the future buy-page multi-rail
  picker. When omitted (today's behavior), the daemon picks the first
  rail the product's merchant profile exposes — which is correct for
  single-provider operators AND back-compat for any pre-:52 client
  not yet sending the field.

  Provider resolution: product → merchant_profile → rail →
  resolve_provider_for_profile_rail. The redirect_url defaults to the
  profile's post_purchase_redirect_url (with {invoice_id} substitution)
  if set, else Keysat's own /thank-you. New invoices carry their
  provider's id via the new create_invoice_with_currency parameter.

api/webhook.rs
  issue_license_for_invoice now passes snapshot fields when calling
  subscriptions::create_subscription — both merchant_profile_id (from
  product lookup) and payment_provider_id (from the invoice row).

main.rs
  Replaces the legacy "active provider preference" boot loader with a
  default-profile-first-provider warm-up. The legacy state.payment
  singleton stays populated for back-compat with call sites that
  haven't yet migrated to the on-demand resolution path. Pre-migration
  fallback to the old singleton-config loaders preserved so the
  daemon still boots cleanly on a DB that hasn't run 0020 yet.

Remaining for part 3:
  - BTCPay + Zaprite connect flows take merchant_profile_id and
    INSERT into payment_providers (currently still write to the
    dropped singleton tables, broken post-migration).
  - api/payment_provider.rs activate endpoint becomes irrelevant in
    the new model — repurpose as list-providers, or delete.
  - Thank-you page (api/mod.rs) provider-kind lookup ports to the
    invoice's recorded provider.
  - Webhook routes refactor to /v1/{kind}/webhook/{provider_id}.
  - Admin UI for Merchant Profiles + product picker + buy-page brand
    block + rail picker.
  - Tier-cap wire-up for unlimited_merchant_profiles entitlement.
  - Version bump to :52 + release notes.

Build: cargo check passes. Deprecation warnings remaining flag exactly
the call sites listed above as the part 3 todo list.

Grant 04e0dcd591 WIP — merchant profile foundation (multi-provider payment model, part 1)
Lays the schema + types + resolution layer for the merchant-profile-aware
multi-provider model documented in plans/multi-provider-payment-model.md.
Does NOT yet migrate any existing call site — legacy `state.payment_provider()`
and the singleton config tables continue to work via deprecation shims so
the daemon keeps running unchanged on this checkpoint.

This commit is intentionally a WIP foundation, not a shippable release —
no version bump, no release notes, no admin UI, no call-site migration.
A follow-up cycle ports purchase / subscriptions / reconcile / upgrade /
tipping to the new resolution layer, rebuilds the BTCPay + Zaprite connect
flows around merchant_profile_id, refactors webhook URLs to
/v1/{kind}/webhook/{provider_id}, ships the Merchant Profiles admin UI
section, wires the tier-cap, and bumps to :52 with the one-way migration
release notes.

What landed:

migrations/0020_merchant_profiles.sql
  Full schema + data port + DROP of the singleton tables. Creates
  merchant_profiles, payment_providers (FK to profile, unique per
  (profile, kind)), merchant_profile_rail_preferences (tie-breaker
  when a profile has 2 providers serving the same rail). Adds
  merchant_profile_id to products + (merchant_profile_id, payment_provider_id)
  to subscriptions for the snapshot-on-create semantics. Ports
  btcpay_config + zaprite_config + active_payment_provider setting
  into the new tables, then drops them. Master operator post-migration
  step: update the Zaprite webhook URL on the Zaprite dashboard to
  the new /v1/zaprite/webhook/{provider-id} form (or click Reconnect
  Zaprite in the new UI once it ships).

src/merchant_profiles.rs (new module)
  MerchantProfile struct + NewMerchantProfile + MerchantProfileUpdate
  input types. Business-logic CRUD helpers: create, get, get_default,
  require_default, list, update, set_default, delete, for_product.
  Delete refuses if products or active subs are attached or if it's
  the default profile. Tier-cap check stubbed with a TODO for the
  next chunk's tier.rs wire-up.

src/db/repo.rs (+469 lines)
  Repo helpers: create/get_by_id/get_default/get_for_product/list/
  update/set_default/delete for merchant_profiles + count helpers
  for products/active_subscriptions per profile. PaymentProviderRow
  struct + create/get/list_for_profile/list_all/delete. RailPreference
  struct + list/set/clear helpers. update_merchant_profile builds a
  dynamic SET clause so partial updates don't clobber fields the
  caller didn't touch.

src/payment/mod.rs
  Rail enum (Lightning / Onchain / Card) + ProviderKind::parse +
  rails_for_kind static mapping. build_provider(row, public_base) ->
  Arc<dyn PaymentProvider> factory that dispatches on kind to construct
  a typed BtcpayProvider or ZapriteProvider from a payment_providers
  row. PaymentProvider trait gains a default served_rails() impl
  returning rails_for_kind(self.kind()).

  Deprecation shims: SETTING_ACTIVE_PROVIDER constant +
  read_active_provider_preference + write_active_provider_preference
  stay callable so btcpay_authorize/zaprite_authorize/main.rs/the
  thank-you page still build. read_active_provider_preference now
  reads from the new payment_providers table (returns the kind of
  the first provider attached to the default profile), falling back
  to the legacy settings-table read pre-migration. write_* is a no-op.
  Each shim has a #[deprecated] attribute so the build surfaces
  exactly which call sites still need porting (lit up in the
  follow-up cycle's TODO).

src/api/mod.rs (AppState)
  New methods alongside the existing payment_provider() shim:
    - payment_provider_by_id(id) — looks up a row, builds the provider
    - merchant_profile_for_product(product_id) — resolves via products.merchant_profile_id, falls back to default
    - resolve_provider_for_profile_rail(profile_id, rail) —
      preference table -> single candidate -> deterministic earliest-
      connected with WARN. Returns (row, Arc<dyn PaymentProvider>).
    - resolve_provider_for_product_rail(product_id, rail) — convenience
      wrapping the previous two.

src/lib.rs
  Registers the new merchant_profiles module.

Build state: cargo check passes. Only warnings are the pre-existing
unused-import in recover.rs and the deprecation lint firing on the
five legacy call sites enumerated in the WIP plan.

Grant d927e4940f v0.2.0:40 — discount-code slot reaper for abandoned checkouts
Eager reservation at /v1/purchase prevents code-cap races but leaked
slots if BTCPay never fired the expiry webhook. New 5-min background
reaper scans for pending redemptions tied to expired/invalid invoices
or pending invoices older than 30 min, cancels each, and decrements
used_count so the slot returns to the pool.

Grant 3c054c65db v0.2.0:22 — Policy scope is editable on discount codes
Lifts the "scope cannot be edited" rule for policies. Product scope
remains read-only (moving a code between products has weird semantics
for historical redemptions), but the tiers a code applies to can now
be refined in-place via the Edit form's pill multi-picker.

- repo::update_discount_code: new applies_to_policy_id param
  (Option<Option<String>>) alongside the existing applies_to_policy_ids
  multi field. Both update the right columns; caller passes a
  consistent pair so singular + JSON columns don't drift.
- Admin PATCH endpoint: new optional `policy_slugs` field. Server
  resolves slugs against the code's existing product, then normalizes:
  - [] → both columns NULL (any policy on the product)
  - [one] → singular column set, JSON column cleared
  - [two+] → JSON column set, singular column cleared
  Sending no `policy_slugs` leaves scope alone (back-compat).
- Edit form: pill multi-picker replaces the read-only Applies-to label.
  Pre-selected from the code's current allowed-policy set. Product
  label stays read-only above the picker.

Grant 094cf75e52 v0.2.0:20 — Multi-policy scope for discount codes
A discount code can now apply to a subset of policies on a product
(e.g. "Patron and Pro but not Creator") instead of being limited to
exactly one policy or the entire product.

- Migration 0018 adds `applies_to_policy_ids_json` (nullable JSON array
  of policy ids). Legacy `applies_to_policy_id` stays as the singular
  fallback when the JSON column is empty/NULL.
- `DiscountCode::allowed_policy_ids()` helper unifies multi + singular
  into one Vec. Purchase + preview scope checks consult it.
- `find_applicable_featured_discount` now narrows multi-policy
  candidates in Rust (small candidate set; index-friendly SQL would
  require json_each, deferred).
- Admin API: `POST /v1/admin/discount-codes` accepts `policy_slugs`
  (array) alongside the existing `policy_slug` (singular). Multi wins
  when both are present. PATCH does not allow scope edits — same rule
  as the singular field (disable + recreate to re-scope).
- UI: pill multi-select replaces the policy dropdown on the create
  form. Edit modal's scope label renders the comma-separated list.

UI + schema both back-compat: existing codes keep working unchanged.

Grant 4334a9f044 v0.2.0:16 — Launch-special discount codes + marketing bullets
Major feature release.

Featured (launch-special) discount codes:
  - New 'featured' flag on discount_codes (migration 0017). When true,
    the buy page renders a diagonal LAUNCH SPECIAL ribbon + slashed
    original price + new price for every applicable tier. Purchase
    endpoint auto-applies the discount for buyers who don't type a
    code. Operator-typed codes still win.
  - find_applicable_featured_discount repo helper: most-specific match
    (policy > product > global), tiebreak by created_at.
  - GET /v1/products/<slug>/policies now returns featured_discount per
    policy with the post-discount price computed server-side. SDK
    consumers + the dynamic pricing page get this for free.

Marketing bullets on policies:
  - metadata.marketing_bullets — operator-controlled copy that renders
    as additional checkmarks above the entitlement bullets on both the
    admin grid tier card and the buy page tier. For things like 'Up
    to 5 products' or 'BTCPay integration' that aren't real
    entitlement gates.
  - Authored via textarea on draft + edit policy forms.

UI:
  - 'Most popular' checkbox now on the draft tier card (was edit-only).
  - Discount codes tab grouped by product (matching Licenses /
    Subscriptions tabs). Each code row gets a 'featured' badge when
    flagged.

All 87 tests still pass. Migration is additive, no SDK changes,
backwards-compatible.

Grant 519fa1a8e6 v0.2.0:14 — Entitlements catalog read fix + drag-and-drop tier ordering
Bug fix:
  Product entitlements catalog reads were silently dropping. Every
  SELECT against the products table was missing entitlements_catalog_json
  from the column list, so the PATCH handler wrote the catalog correctly
  but every subsequent read returned null. Admin UI edits appeared to
  vanish on save. Fix: added the column to all four product SELECTs
  in repo.rs (list_products, get_product_by_slug, get_product_by_id —
  one column list, replace_all). Added regression test
  product_entitlements_catalog_round_trips_through_list_endpoint that
  exercises the full PATCH → list round-trip the admin UI hits.

UX:
  Drag-and-drop reordering on the tier-card grid. Operator drags any
  tier card to a new position; on drop, parallel PATCH requests set
  tier_rank 1..N based on the new visual order. Archived tiers are
  excluded (their position in the ladder is moot). Edit-policy modal
  retains the tier_rank number field for the two cases drag-and-drop
  can't express (precise override + blank-to-remove-from-ladder).
  Cursor signals grab/grabbing on hover/drag; dragging card lifts +
  fades for visual feedback.

Copy:
  Policies-tab section headers now show just the product name
  ("Keysat") instead of redundant "Keysat — keysat". Entitlements-
  catalog row editor description placeholder shortened from
  "Description (shown on buy page tooltip)" to "Description (buyer
  tooltip)" so it fits the column; full hover hint kept on the
  input's title attribute.

Test count: 87.

Grant 257669092b v0.2.0:11 + v0.2.0:12 — Archive, Settings, agent surface, machines redesign
Two release cycles prepared together: v0.2.0:11 (policy archive + safe-
delete cleanup + brand-consistent confirm modals) and v0.2.0:12 (Settings
tab + agent-friendly operator API + machines tab redesign + buyer-facing
copy alignment).

Highlights:

- Migration 0015: policies.archived_at column. Archive button on tier
  cards; safe-delete relaxed to ignore revoked-license tombstones;
  renewal worker refuses archived policies.
- Migration 0016: scoped_api_keys table. Four roles (read-only,
  license-issuer, support, full-admin) with bounded scopes. Master
  admin_api_key still works on every endpoint; scoped keys gated on
  endpoints wired through require_scope().
- New /v1/openapi.json — public, no auth. Curated OpenAPI 3.1 spec
  for agent / SDK discovery.
- New Settings tab: Operator name + Payment providers panel + API
  keys management. Replaces 8 StartOS Actions (Zaprite all, BTCPay
  all, operator name, switch-provider). StartOS Actions pruned to 4
  install-time essentials.
- Machines tab rewritten: global default view grouped by product,
  filter pills with counts, quick-stats row, drill-down via new
  "Machines" button on each Licenses-tab row. New repo helper
  list_machines_admin joins machines x licenses x products
  server-side.
- Branded confirmModal replaces every native window.confirm() call
  in the admin UI (7 callsites).
- Enforce mode killed: KEYSAT_LICENSE_ENFORCE compile-time flag
  retired; daemon always boots; missing self-license -> Creator
  (free) tier. "Unlicensed" label gone from admin UI.
- Zaprite gated on the new zaprite_payments entitlement (renamed
  from card_payments to reflect the broader gateway).
- Creator code cap 5 -> 10.
- KEYSAT_AGENT_GUIDE.md: auth, role-to-scope mapping, error envelope,
  webhook events, worked recipes.
- Buyer-facing copy aligned with new positioning: "Bitcoin-native
  self-hosted software licensing" everywhere on production surfaces.
- Cross-product safety section (Section 9a) added to KEYSAT_INTEGRATION.md.
- 5 new API integration smoke tests covering OpenAPI, scoped API
  keys CRUD, role-elevation guard, and Zaprite-tier gating.

Test count: 83 passing (was 78). All migration tests pass against
0015 and 0016 applied to populated DBs.

Grant 68dfe7f6fc Product entitlements catalog (Phase 1: schema + admin + buy page)
Closes the request to make entitlements first-class on products
instead of free-text strings on policies. Operators declare the
closed list of entitlements a product offers — slug + display name
+ optional description — and policies pick from that list with a
click-to-toggle bubble UI. Buy page renders human-readable names
("AI summaries") with descriptions as tooltips, never the raw slug
("ai_summaries").

Schema (migration 0014):
- products.entitlements_catalog_json: nullable JSON column shaped
  as [{slug, name, description}, ...]
- Auto-backfill on upgrade: for each existing product, derive a
  catalog from the union of its policies' entitlement slugs, with
  name = slug.replace('_', ' ') and empty description. Operators
  can refine afterward.
- Products with no policy entitlements stay NULL (legacy
  free-text mode preserved).

Server:
- Product struct gains entitlements_catalog: Option<Vec<EntitlementDef>>
- repo::set_product_entitlements_catalog (validates lowercase ASCII
  slugs, uniqueness, defaults name to slug if empty)
- Product create/update API accept entitlements_catalog;
  update uses double-Option PATCH shape so operators can clear
- Closed-list validation: when product has a non-empty catalog,
  policy create + update reject any entitlement slug not in the
  catalog with a clear error pointing at the right path
- /v1/products/<slug>/policies surfaces entitlements_catalog
  in the product object so SDK consumers can render display
  names client-side
- Buy page renders entitlement display names + description tooltips
  on tier cards (falls back to raw slug for legacy entries that
  predate the catalog)

Admin UI:
- New catalogEditor() helper (repeating slug/name/description rows
  with add/remove buttons) embedded in product create + edit forms
- New entitlementBubblePicker() helper (click-to-toggle pill chips
  showing display name with description tooltip)
- Policy create form: entitlements input swaps based on the chosen
  product's catalog — bubble picker when catalog has entries,
  legacy textarea otherwise. Rebuilds when operator changes
  product.
- Policy edit modal: same bubble-picker-or-textarea swap, scoped
  to the policy's product
- Policy list table: entitlement column shows display names
  (resolved against the product's catalog) instead of slugs

Migration regression test verifies:
- Backfill correctly unions entitlements across all of a product's
  policies, deduplicates, applies name = slug-with-underscores-as-
  spaces transformation
- Products with no policy entitlements get NULL (not [])
- Manually-set catalog values round-trip
- Schema is otherwise FK-clean post-migration

Test count: 78 (was 77; +1 for migration_0014_backfills_*).

Phase 2 (SDK updates + integration doc + side-by-side card-grid
policy authoring UI) ships in follow-up commits before v0.2.0:8.
2026-05-10 07:55:14 -05:00
Grant 2fbd36fac6 P0 — recurring + trial + renewal-webhook + self-tier live refresh
Five fixes that were all blocking real-world use of the recurring
+ tier-upgrade features. All deeply related; bundling them into one
commit because they share data flow and would be silly to land
piecemeal.

1. Subscription row created on recurring purchase
   issue_license_for_invoice now calls
   subscriptions::create_subscription whenever the resolved policy
   has is_recurring=1. Previously the licenses row was inserted but
   no corresponding subscription, so the renewal worker never picked
   it up — buying a recurring policy was silently equivalent to a
   one-shot purchase. Idempotent against webhook re-delivery.

2. trial_days actually does something
   /v1/purchase short-circuits BEFORE pricing/discount logic when
   the chosen policy has is_recurring=1 AND trial_days > 0:
   synthesizes a free invoice via repo::create_free_invoice,
   issues the license inline with expires_at = now + trial_days,
   creates the subscription with next_renewal_at = trial_end so the
   renewal worker fires the FIRST paid invoice when the trial ends.
   Buyer pays nothing today. Discount codes are deliberately
   ignored on trial purchases (free + discount = no-op).

3. Trial license carries the TRIAL flag
   In the regular webhook issuance path, is_trial is now set
   whenever (policy.is_trial OR (is_recurring AND trial_days > 0)),
   so the signed payload's TRIAL bit reflects what the buyer is
   actually getting and SDK consumers can render
   "trial — N days remaining" correctly.

4. Renewal-pending webhook payload enriched
   subscription.renewal_pending now includes buyer_email (looked up
   from the license), product_id, policy_id, cycle_start_at,
   cycle_end_at, due_at, and is_first_paid_cycle. With these the
   operator's webhook receiver has everything it needs to render
   "your free trial is ending" vs "your monthly renewal is due"
   emails and forward the checkout_url to the buyer. Without this
   payload upgrade, renewal invoices were created server-side but
   no one knew about them.

5. Self-tier live refresh
   New license_self::refresh_self_tier_from_db re-reads the
   daemon's own license row from the local DB and rebuilds
   state.self_tier with LIVE entitlements (not the immutable
   signed-payload entitlements). Without this, an admin Change
   Tier on the daemon's own license never propagates — the
   running process keeps showing whatever tier was baked in at
   key-signing time, even though the DB row says otherwise.
   Wired to run:
   - Once at boot, immediately after check_at_boot (so any tier
     change between two daemon runs takes effect on next start)
   - Every hour thereafter (background task in main.rs)
   - On demand via POST /v1/admin/self-license/refresh, exposed
     for operators who don't want to wait for the next tick

   For master Keysat (the one selling licenses) the refresh
   query is local. Non-master operators in v0.3+ can extend this
   to call upstream `/v1/validate`. For v0.2.x, local-DB-only
   resolves your testing case (downgrade yourself, click refresh,
   sidebar updates, gate tests work).

6. Buy page CTA reflects trial
   When the selected tier has is_recurring=1 and trial_days > 0,
   the price card renders "FREE for N days" and the button reads
   "Start N-day free trial" instead of "Pay with Bitcoin". Buyer
   knows they aren't being charged today.

7. Invoice model gains listed_currency + listed_value
   Already in the DB schema (migration 0010); the Rust model just
   wasn't reading them. Needed by #1 to set the subscription's
   listed_value correctly for fiat-priced recurring policies.

Test count unchanged (77 passing). The recurring-tests-still-pass
proof point isn't the test suite (these are behavioral changes
above the renewal-worker tests' scope) — it's that the renewal
worker tests construct subscriptions explicitly and don't go
through the purchase path that was broken.

Grant f8affdb11f Tier upgrades Phase 2 — quote logic + apply step
Builds on 8ce78ab (Phase 1 schema). Pure module work — no HTTP
endpoints yet (those are Phase 3). Operator-invisible until Phase
3-5 wire up the buyer / admin / UI surfaces.

src/upgrades.rs:
- UpgradeQuote / TierDirection / EffectiveAt structs (serde-ready
  for the future endpoint).
- compute_upgrade_quote(state, license, target_policy) — the
  buyer-facing quote function. Enforces ladder rules:
    * both policies must have non-NULL tier_rank
    * sideways (same-rank) changes rejected — admin-only
    * cross-product target rejected
    * inactive target rejected
    * same-policy noop rejected
    * perpetual downgrades rejected (refund decision = admin-only)
    * recurring → perpetual downgrade rejected (admin-only)
- Branches on perpetual vs recurring:
    * Perpetual upgrade: flat (target - current) listed price diff,
      effective_at = Immediate.
    * Recurring upgrade: prorated (target - current) × days_remaining
      / period_days; effective_at = Immediate; surfaces
      next_renewal_charge for the buyer to see what they'll pay
      going forward.
    * Recurring downgrade: zero-charge today, effective_at =
      next_renewal_at (full current cycle at old price).
    * Free → recurring: full first-cycle price (no proration since
      "remaining value" of free is 0).
- record_tier_change — INSERT helper for the audit row.
- apply_tier_change — UPDATE helper that mutates the license row
  (policy_id, entitlements_json, expires_at, max_machines,
   grace_seconds, is_trial) and any tied subscription
  (policy_id, listed_value, period_days). Recurring → perpetual
  apply also cancels the now-orphaned subscription so the renewal
  worker stops touching it.
- get_tier_change / list_tier_changes_for_license /
  get_tier_change_by_invoice — read helpers (Phase 3 webhook
  handler will use the by_invoice variant).

tier_rank threading:
- models::Policy gains `tier_rank: Option<i64>`.
- POLICY_COLS + row_to_policy include tier_rank with try_get
  Option<i64> + flatten so NULL stays NULL (a valid state) and
  pre-0013 databases also resolve to None.
- repo::create_policy gets a `tier_rank: Option<i64>` param.
- repo::RecurringUpdate gains `tier_rank: Option<Option<i64>>`
  for nullable-patch semantics matching price_sats_override.
- CreatePolicyReq + UpdatePolicyReq accept tier_rank with the
  same shape; range-validated 0..=1000.

tests/upgrades.rs (8 new tests):
- perpetual_upgrade_quote_returns_flat_price_difference
- perpetual_downgrade_is_admin_only (rejection w/ helpful msg)
- quote_rejects_target_with_null_tier_rank
- quote_rejects_same_policy
- recurring_upgrade_prorates_against_time_remaining (asserts
  ~half-of-diff for ~half-of-cycle remaining; tolerance window)
- recurring_downgrade_is_zero_charge_at_next_cycle (verifies
  effective_at lands on next_renewal_at)

Grant c301eacfaa Recurring subs Phase 4 — admin UI + buy-page rendering + Pro-tier gate
Phase 4 surfaces the recurring-subscription schema (migration 0011) and
renewal-worker (Phase 2, commit 7007bf8) through every layer operators
and buyers actually see:

API
- Policy struct + repo gain is_recurring, renewal_period_days,
  grace_period_days, trial_days. RecurringConfig / RecurringUpdate
  helper structs keep create_policy / update_policy signatures
  manageable.
- CreatePolicyReq + UpdatePolicyReq accept all four fields. Validation
  rejects internally inconsistent combos (recurring=true with period=0,
  trial > renewal period, period >5y, grace >90d).
- New tier::enforce_recurring_feature gate. Pro/Patron only — Creator
  and Unlicensed get a 402 with upgrade_url. The gate fires on both
  create-policy and the false→true transition in update-policy.
- list_public_policies now surfaces is_recurring, renewal_period_days,
  trial_days so SDKs and the buy page can render cadence.

Admin UI (web/index.html)
- Create-policy form gets a "Recurring subscription (Pro)" section:
  is_recurring checkbox + cadence preset (monthly/quarterly/etc/custom)
  + grace period + trial days. Live enable/disable: the inputs gray
  out unless the box is ticked, and the custom-days input grays out
  unless "Custom" is selected.
- Edit-policy modal mirrors the same section, pre-populated from the
  policy's current values.
- Policies-list table shows a gold "every Nd" badge alongside the
  trial badge so operators can see at a glance which policies renew.

Buy page (/buy/<slug>)
- Tier cards on a recurring policy render a "Renews monthly/annually/
  every N days" meta line + a "/mo" / "/yr" / "/Nd" suffix on the
  price unit, so the headline reads "$25 / mo" not just "$25".
- First-cycle trial banner shows when trial_days > 0.
- TIERS JSON map exposes is_recurring + renewal_period_days +
  trial_days so the JS price-update path keeps the cadence suffix
  in sync when the buyer clicks between tiers.

Tests (+4, total now 53)
- recurring_policy_blocked_on_creator_tier — 402 + upgrade_url
- pro_tier_creates_monthly_recurring_policy — full create + verify
  via both admin GET and public list endpoint
- recurring_requires_positive_period — validator rejects period=0
- edit_policy_to_recurring_respects_tier_gate — Creator 402 on flip,
  Pro 200 on same flip, name-only PATCH on already-recurring policy
  doesn't re-fire the gate after downgrade

Drive-by: wrap the state-machine ASCII diagram in subscriptions.rs in
a ```text fence so cargo's doc-test runner stops trying to compile box
characters as Rust tokens.

Grant 45e0cd2bd1 Edit-product currency support — operators can switch SAT ↔ USD/EUR in place
Closes the last multi-currency gap before v0.2.0:0 cutover. Operators
who created a product in one currency can now switch to another via
the Edit modal — no need to disable + recreate.

Backend:
- PATCH /v1/admin/products/:id accepts price_currency + price_value
  alongside the legacy price_sats. Same validation shape as the
  create endpoint (whitelist SAT|USD|EUR, mismatched legacy + typed
  → 400).
- repo::update_product_with_currency replaces the SAT-only
  update_product as the canonical entry; the SAT-only function is
  now a thin wrapper that always passes "SAT". For SAT updates,
  price_sats and price_value are dual-written. For fiat updates,
  price_sats is reset to 0 — gets repopulated by the rate fetcher
  on the next invoice creation against the product.

Frontend (Products → Edit modal):
- Currency picker dropdown next to the price input. Initial value
  reads from the product's current currency.
- For fiat products, the displayed price renders as decimal main
  units ($49.00); save converts to cents on the way out.
- Hint text + step swap as the operator changes currency.
- Doesn't auto-clobber the displayed value when currency changes
  — operator decides if the same number still makes sense.

No schema changes (column shape from migration 0010 is sufficient).

Test count unchanged at 38 — pure handler + UI work, behavior
covered by the existing currency tests on create.

Grant 9919fbf8f8 v0.1.0:50 — auto-recover from sqlx checksum drift on idempotent migrations
Two operators in a row hit the same crash-loop on upgrade:

  Error: running migrations
  Caused by:
      migration 9 was previously applied but has been modified

sqlx records a SHA-384 of each migration's bytes when first applied,
then verifies the on-disk bytes still match on every subsequent boot.
Cross-build drift (trailing newlines, line-ending normalization, etc.)
produces different bytes for semantically-identical SQL — and sqlx
refuses to start. Recovery required SSHing in and running:

  sqlite3 /data/keysat.db "DELETE FROM _sqlx_migrations WHERE version = 9;"

That's bad UX. Worse, every operator going through this version
range hits it once.

Self-heal: db::init now wraps sqlx::migrate!().run() with detection
for MigrateError::VersionMismatch(N) on a constant allowlist of
migrations certified safe to re-run (IDEMPOTENT_MIGRATIONS, just [9]
for now). When triggered, the daemon clears the stale row, retries,
logs a WARN explaining what happened, and continues. No SSH dance.

Allowlist gate is critical — auto-clearing checksums on additive
ALTER TABLE migrations like 0010 would error on retry (SQLite has
no ADD COLUMN IF NOT EXISTS). Only migrations explicitly designed
as drop-and-rebuild (like 0009) and tested via the
`migration_NNNN_is_idempotent` pattern in tests/migrations.rs
qualify.

Regression test in tests/migrations.rs exactly simulates the
production incident:
  1. apply all migrations cleanly
  2. poison v9's recorded checksum with bogus bytes
  3. confirm raw sqlx::migrate! bails (proves the poisoning works)
  4. call db::init — must succeed by clearing + re-applying v9
  5. confirm v9 + v10 are both recorded with non-poisoned checksums

Test count: 38 (was 37; +1 db_init_self_heals test).

For operators currently stuck on the :49 crash-loop: just upgrade
to :50 from the StartOS marketplace. The :50 daemon will see the
mismatch on first boot, auto-clear v9's row, re-apply (0009 is
idempotent by design), and continue to 0010. No manual sqlite3 needed.

Grant d8aa9c22b9 Multi-currency Phases 3, 5, 6 — buy page, invoice rate recording, discount currency
Phase 5 (invoice records the rate):
- repo::create_invoice_with_currency takes the listed currency,
  listed value, exchange_rate_centibps, and exchange_rate_source as
  optional params; create_invoice (the legacy form) becomes a thin
  wrapper that passes None for all four. SAT-priced flows are
  unchanged.
- purchase::start now branches on product.price_currency: SAT keeps
  the existing path; USD/EUR calls rates::convert_to_sats and pins
  the listed price + rate to the local invoice row for audit. The
  buyer is still billed in BTC (BTCPay invoice is sat-denominated)
  but the audit trail records what they SAW vs what they were
  charged.
- Test paid_purchase_in_usd_records_listed_currency_and_rate seeds
  a manual rate pin ($50k/BTC), creates a USD-priced product
  ($49.00), runs through purchase, asserts the invoice row carries
  listed_currency='USD', listed_value=4900, rate_centibps=
  500_000_000, source='manual_pin', amount_sats=98_000.

Phase 3 (buy page renders fiat):
- Server-rendered initial price respects product.price_currency:
  USD products show "49.00 USD" (cents converted to display dollars)
  instead of sats. Tier-picker JS still formats per-tier prices in
  sats — that's a v0.3 polish when we plumb the rate into the JS
  render path. Most operators ship single-policy products at first,
  so the static initial render is the high-leverage piece.

Phase 6 (currency-aware discount codes):
- POST /v1/admin/discount-codes accepts optional `discount_currency`
  field ('SAT' default, 'USD', 'EUR'). Whitelisted in the handler.
- repo::create_discount_code is now a thin wrapper around
  create_discount_code_with_currency; the new helper persists
  discount_currency to the column added in 0010. Existing SAT-only
  codes keep working unchanged.

Test count: 37 (was 36; +1 paid_purchase_in_usd test).

Multi-currency design phases 1-6 all shipped (1: schema in :48; 2:
admin UI write in :48-:49; 3: buy page; 4: rate fetcher; 5: invoice
audit; 6: discount currency). Phase 7 (recurring subscriptions
re-quote) is v0.3 territory — needs the recurring-billing scaffolding
from Zaprite first.

Grant 356d17fdde Multi-currency Phase 2 — admin write path (currency picker)
Backend:
- POST /v1/admin/products accepts both forms:
  - legacy: { price_sats: 50000 }
  - typed:  { price_currency: 'USD', price_value: 4900 }
  Whitelist enforced (SAT|USD|EUR). Mismatched legacy + typed → 400
  to catch half-migrated clients sending stale price_sats alongside
  fresh price_value.
- repo::create_product_with_currency: SAT → dual-write price_sats =
  price_value; USD/EUR → price_sats = 0 until first invoice creation
  triggers a rate lookup (Phase 4 + 5).
- Test admin_create_product_accepts_legacy_and_typed_currency_forms
  pins 6 happy/sad paths.

Frontend (Products page):
- Create-product form has a currency picker (sats / USD / EUR).
  Picker swaps the unit hint + step in place.
- Decimal entry on USD/EUR is converted to cents on the way out.
- Products table renders prices via formatProductPrice(): USD
  products show "$49.00" with optional "≈ 75k sats" hint.

Test count: 34 (was 33).

Grant d8fcb51d1c Multi-currency schema foundation (Phase 1 of MULTI_CURRENCY_DESIGN)
Migration 0010 adds the columns needed to price products + policies
in something other than satoshis (USD, EUR, BTC at higher denoms)
while keeping every existing operator's data behaviorally identical.
This is the foundation work; admin UI write path, buy page
rendering, and rate fetcher land in subsequent phases. See
MULTI_CURRENCY_DESIGN.md at the parent licensing/ folder for the
full design.

Schema changes (all additive):
- products gain price_currency (TEXT NOT NULL DEFAULT 'SAT') and
  price_value (INTEGER NOT NULL DEFAULT 0). Backfill copies
  price_sats → price_value on every existing row, so SAT-priced
  products carry their information identically through the
  migration.
- policies gain price_currency_override (nullable, NULL = inherit
  from product) and price_value_override (nullable, mirrors the
  existing price_sats_override).
- invoices gain four nullable columns: listed_currency, listed_value,
  exchange_rate_centibps, exchange_rate_source. NULL on every
  current row; populated by the daemon when an invoice is created
  against a fiat-priced product.
- discount_codes gains discount_currency (DEFAULT 'SAT'). 'percent'
  codes are currency-agnostic; 'fixed_sats' and 'set_price' codes
  use this column to express "$10 off" or "set price to $25"
  against fiat-priced products.
- New index idx_products_currency for future "list products by
  currency" admin views.

Read path:
- Product struct gains price_currency + price_value fields
  (#[serde(default)] for back-compat with any cached/persisted
  shapes that predate them).
- row_to_product extracts the new columns; falls back to SAT/
  price_sats if a row predates 0010 (defensive — migration always
  runs at boot, but no reason to crash if it didn't).
- All four product SELECTs add the new columns.

Write path (legacy SAT-only callers):
- create_product dual-writes price_sats AND price_value to the
  same value, with price_currency = 'SAT'.
- update_product dual-writes price_sats and price_value when the
  caller passes a new sat price.

Migration regression test:
- migration_0010_backfills_existing_products_to_sat seeds three
  products (free, $100, $2500-equivalent) and a policy with a
  sat override BEFORE 0010 runs, applies 0010, asserts every row
  ends up with price_currency = 'SAT' and price_value =
  price_sats. Catches any future change that breaks the
  backfill contract.
- migration_0009_is_idempotent now pinned to 0009 by filename
  (was: "the last migration"). 0010+ are not idempotent (ALTER
  TABLE ADD COLUMN can't be retried in SQLite); the
  idempotency test is specifically for 0009 because that
  migration's whole point was being safely re-runnable.

Test count: 33 (was 32; +1 migration_0010_backfills test).

Decisions locked in (per MULTI_CURRENCY_DESIGN open questions):
- Default currency on new products: SAT. Operators explicitly
  pick USD for fiat-priced products.
- Multi-currency available to all tiers (NOT gated behind Pro/
  Patron) — the right product call.
- Rate source priority: Kraken → Coinbase → CoinGecko (lands
  in Phase 4 of the design).
- Recurring subscriptions: SAT-priced subs charge the same sat
  amount each cycle (no rate adjustment needed); USD-priced subs
  re-quote each cycle so the dollar amount is stable.

Grant f9ef1a854c Webhook DLQ — list failed deliveries and manually retry
Closes the silent-loss hole in outbound webhook delivery. The worker
in src/webhooks.rs retries failed deliveries with exponential backoff
up to 10 attempts, then sets next_attempt_at = NULL and walks away.
Pre-this-commit, those "dead-lettered" rows sat in webhook_deliveries
forever with no surface for the operator to discover, inspect, or
recover from them — a subscriber that was down for >6h during a
license-issuance burst would silently lose those events forever.

What's new:

- repo::DeliveryStatusFilter — enum with parse() so query strings
  map cleanly to SQL predicates.
- repo::list_deliveries — endpoint_id + status + limit, newest first.
- repo::requeue_delivery — resets attempt_count=0, clears delivered_at
  and last_error, sets next_attempt_at=now. The worker picks it up on
  the next 5s tick.

- src/api/webhook_deliveries.rs — admin module with two handlers:
  - GET /v1/admin/webhook-deliveries?endpoint_id=…&status=…&limit=…
  - POST /v1/admin/webhook-deliveries/:id/retry  (audit-logged as
    webhook_delivery.retry; 404 on missing id)
- Routes registered in src/api/mod.rs alongside the existing
  webhook_endpoints CRUD.

- tests/api.rs gains webhook_dlq_lists_failed_and_retry_requeues:
  seeds three deliveries directly via SQL (one each: delivered,
  pending, dead-lettered), exercises the list filter, runs the retry,
  asserts the row migrates from failed→pending, audit row is written,
  404 on bad id, 400 on bad status filter.

Worker code is unchanged. The DLQ is operator-actionable infrastructure
on top of the existing retry semantics.

Test count: 23 (9 unit + 4 migration + 10 API), up from 22.
