* fix: auto initialize default send balance
* fix: tighten send access auto init flow
* refactor: centralize send balance state
* fix: separate legacy repair from admin control in send balance
Add an `address_sender.source` column to distinguish legacy / auto /
user / admin rows. `ensureDefaultSendBalance` now only repairs rows
with `source IS NULL`, so admin-disabled and user-requested rows are
never overwritten. Admin POST writes tag `source = 'admin'`; new
auto-init inserts tag `'auto'`; `requestSendMailAccess` inserts tag
`'user'`.
Bumps DB_VERSION to v0.0.8 with the usual `PRAGMA table_info` guarded
ALTER, plus a standalone SQL patch under db/.
Adds E2E regressions: legacy repair path, admin-disabled rows stay
disabled across settings and send, send after admin deletion
auto-initializes a fresh row.
* fix: drop runtime legacy repair; backfill source='legacy' on migrate
Pre-v0.0.8 schema cannot distinguish legacy request-send-access
remnants from admin-disabled rows — both share `balance = 0,
enabled = 0`. Letting ensureDefaultSendBalance repair that shape on
upgrade could silently re-enable an admin-disabled row.
Remove the runtime repair path entirely:
- `ensureDefaultSendBalance` now uses `ON CONFLICT(address) DO NOTHING`;
existing rows are never touched.
- The v0.0.8 migration (and the matching SQL patch) backfills every
pre-existing row with `source = 'legacy'`, making pre-migration
state explicitly off-limits to runtime auto-init.
- E2E: flip the legacy test to the negative direction — a
`source='legacy'` zero-balance row stays untouched by settings
reads and send attempts. Harden `resetSenderToLegacy` to return
404 when `meta.changes < 1`.
- Update changelog and docs: legacy/admin-disabled rows must be
restored manually via the admin UI.
* refactor: collapse send balance auto-init to missing-row insert
Per review feedback: the runtime guarantee we actually need is
"create an address_sender row when one is missing, leave existing
rows alone". Once `ensureDefaultSendBalance` switched to
`ON CONFLICT DO NOTHING`, the `source` column, the v0.0.8 migration,
and the `resetSenderToLegacy` test endpoint became dead weight —
the DO NOTHING path already protects admin-disabled and admin-edited
rows without any provenance metadata.
- Drop `address_sender.source` and the v0.0.8 migration; revert
DB_VERSION to v0.0.7. No schema change ships with this PR.
- Strip the `source` field from `ensureDefaultSendBalance`,
`requestSendMailAccess`, and the admin-update path.
- Remove the `/admin/test/reset_sender_to_legacy` test endpoint and
its E2E helper; the negative legacy-repair test it served is no
longer needed because the runtime no longer touches existing rows.
- E2E coverage stays focused on the three guardrails: missing-row
auto-init, admin-disabled rows stay disabled, admin deletion
triggers a fresh re-insert.
- Tighten changelog and docs to "auto-initialize missing rows".
* docs: align common-issues with missing-row-only auto-init
The FAQ entries for "DEFAULT_SEND_BALANCE set but still No balance"
still described the old behaviour of repairing legacy
`balance = 0 && enabled = 0` rows. Rewrite both zh and en rows to
match the current runtime: only addresses with no existing
`address_sender` row get auto-initialised; legacy, admin-disabled,
and admin-edited rows must be restored manually through the admin
console.
