The wizard serialized the whole accumulating form state into a `snapshot` hidden field
(pr-str EDN + custom readers), decoded it every request, and merged step-params back in.
For this single-step modal the snapshot is pure redundancy: every value is either in the
entity or the live posted form. Remove it:
- render: EditWizard.render-wizard renders a plain form -- no snapshot / edit-path /
current-step hidden fields; a single `db/id` hidden rides in the form instead.
- middleware: wrap-derive-state rebuilds :multi-form-state per request from the entity
(loaded by the db/id hidden) overlaid with the live step-params, replacing
wrap-init-multi-form-state + wrap-entity. The ~34 :snapshot reads are unchanged --
:snapshot is now a derived map, not a round-tripped blob.
- editable fields (accounts, vendor, memo, approval, action, mode, amount-mode) come ONLY
from the posted form (absent = cleared) so removing all account rows doesn't resurrect
the entity's persisted accounts; only entity-only fields (db/id, client, amount, ...)
come from the entity.
- delete the dead initial-edit-wizard-state and render-account-grid-body.
- e2e: make removeAllAccounts re-query each iteration (whole-form swaps stale a captured
row index) and restore the percentage test to type-then-add ordering.
Scorecard: snapshot EDN round-trip + custom readers + merge-multi-form-state -> gone
(snapshot-field renders 0). Verified on a fresh server: full suite 38 pass / 1 unrelated
fail, swap 6/6, transaction-edit 8/8 -- same green as before, snapshot removed.
The 5 manual-coding operations (vendor change, simple/advanced toggle, add row, remove
row, $/% toggle) each had their own route + handler, all doing "mutate form state ->
render-full-form". Fold them into the single edit-form-changed endpoint, which now
dispatches on an `op` form-param to the relevant pure apply-* mutation fn (apply-vendor-
changed / apply-toggle-mode / apply-new-account / apply-remove-account /
apply-toggle-amount-mode) then re-renders. A missing/unknown op (a plain dependent-field
change, e.g. account->location or amount->totals) just re-renders, as before.
- edit.clj: 6 handlers -> 1 dispatcher + 5 pure apply-* fns; markup posts to
edit-form-changed with :hx-vals {:op "..."}.
- routes/transactions.cljc: remove the 5 now-unused route keys.
- e2e specs: retarget the vendor selector by op (div[hx-vals*="vendor-changed"]) and
point the toggle-amount-mode / vendor response waits at edit-form-changed, since the
old per-op route names are gone. (Behavioral assertions unchanged.)
Scorecard: manual-coding routes ~10 -> ~5 (operations now one dispatcher). Parity held:
swap spec 6/6, full suite 32 pass (Shared Location green; no new regression).
The hx-select reference moved running totals into an inline #account-totals tbody that
refreshes via edit-form-changed, so nothing posts to ::route/account-total or
::route/account-balance anymore -- their route handlers were referenced only by their own
registrations. Remove the two handler fns, their route registrations, and the now-unused
route keys from routes/transactions.cljc. The pure account-total* / account-balance* fns
(used inline to render the totals) are untouched.
Scorecard: modal routes ~12 -> ~10. Full suite 31 pass / no regression.
simple-mode-fields* rendered its single account row by rebinding the form cursor to a
synthetic MapCursor rooted at accounts[0] (faking a deep starting position). Replace that
with explicit-data rendering: account-field-name builds the exact field names the cursor
would produce at [:step-params :transaction/accounts 0 field] (via path->name2), and
account-field-errors reads errors from the same path -- no re-rooted cursor.
This is the render-fn rewrite the earlier with-field-default shortcut couldn't be (that
mutated the cursor and broke the simple-mode swap). Scorecard: faked cursor roots 2 -> 0
(both heuristic-1 items now clear for this modal). Parity held: swap spec 6/6 (its vendor
tests run in simple mode), Shared Location save green, full suite 31 pass / no regression.
- gotchas.md: de-faking a cursor is not a drop-in -- with-field-default mutates the
cursor (transact!) as a render side effect and broke the simple-mode swap; the de-fake
belongs with the render-fn rewrite, verified against the swap spec.
- scorecard.md: append the Phase 2 (in-progress) Transaction Edit row -- no-cursor 1->0,
LOC 1608->1555, parity held (swap 6/6 + Shared Location). Faked roots / snapshot /
Selmer / route-collapse remain as the wholesale-rendering continuation of Phase 2.
