Closes the buyer self-service tier-upgrade loop. With this in,
SDKs can wire an "Upgrade to Pro" button inside the operator's
app and the daemon handles quote → invoice → settle → apply
without operator involvement.
New endpoints (auth via signed license_key in body, same model
as /v1/recover and /v1/subscriptions/cancel — no admin token,
no cookie):
- POST /v1/upgrade-quote — read-only quote. "If I upgraded to
<tier>, what would I owe right now,
when do entitlements take effect,
what will the next renewal charge?"
- POST /v1/upgrade — buyer commits. Daemon recomputes the
quote (don't trust client shaping),
rejects 0-charge upgrades (admin path
only), creates a provider invoice for
the prorated charge in the listed
currency converted to sats, persists
the local invoice + a tier_changes
row tying them together, returns the
checkout URL.
Webhook handler change (src/api/webhook.rs):
- On invoice settle, BEFORE the subscription / license-issuance
branches, look up the invoice in tier_changes via
upgrades::get_tier_change_by_invoice. If present, run the
apply path: mutate the existing license's policy_id +
entitlements + max_machines + grace + expires_at, mutate any
tied subscription's policy_id + listed_value + period_days
(so future renewals charge the new tier), audit, fire the new
`license.tier_changed` webhook event, ack 200.
- Idempotent: re-delivered webhook on an already-applied
tier change is a no-op (license.policy_id == target.id check).
- Critically: the existing license_id is preserved. Buyers
keep the same signed key; on next online validation their
app sees the new entitlements. No new license is issued.
Phase 3 scope deliberately excludes:
- Buyer-initiated DOWNGRADES. compute_upgrade_quote already
returns 0-charge quotes for recurring downgrades (effective at
next_renewal_at), but applying that at the cycle boundary
needs renewal-worker integration. Phase 4 lands the admin
endpoint AND the worker hook in one go. For v0.2.x the buyer
endpoint rejects with 400 "admin-only".
- Admin force-change (POST /v1/admin/licenses/:id/change-tier).
Phase 4.
Tests (+6, total now 72):
- upgrade_quote_returns_perpetual_difference (Standard $25 →
Pro $75 = $50 = 5000 cents quote, "immediate" effective)
- upgrade_quote_rejects_garbage_key (401, doesn't leak whether
the target slug exists)
- upgrade_quote_rejects_unknown_target_policy (404)
- upgrade_start_creates_invoice_and_tier_change_row (verifies
the tier_changes row is written tied to the new invoice; the
license is NOT yet on Pro until settle)
- webhook_settle_on_tier_change_applies_instead_of_issuing
(full end-to-end: settle webhook fires → license flips to Pro
+ Pro entitlements appear; license count stays at 1, NO new
license issued; re-delivery idempotent)
- upgrade_endpoint_rejects_buyer_downgrade (400 "admin-only" —
the clear-message path the quote function intercepts with;
Phase 4 will introduce a separate buyer-downgrade path)
