Bryce c892719bd1 feat(ssr): migrate location-select to a Selmer template (Phase 2 — Selmer validated)
First interactive Transaction Edit component rendered from a Selmer template instead of
Hiccup/com/select, proving the render-file path + the Hiccup<->Selmer interop bridge on
real, e2e-covered markup.

- resources/templates/components/location-select.html: plain-HTML <select> with a
  {% for %} over option maps + {% if opt.selected %}.
- location-select*: build options/selected/classes in Clojure (reusing
  inputs/default-input-classes so styling can't drift), render via
  sel/render->hiccup, and embed the fragment back into the still-Hiccup account row.
- skill: finalize selmer-conventions.md from this validated example (was a stub); add the
  cookbook entry; scorecard marks the first Selmer component.

Verified on a fresh server: full suite 38 pass / 1 unrelated fail, swap 6/6,
transaction-edit 8/8 -- the Shared Location test selects through the Selmer <select>,
saves, and spreads Shared -> DT. Verified by string-match + e2e (not byte-parity:
hh/add-class is set-based so class order differs, CSS is order-independent).

Scope note: the modal's remaining attribute-heavy components delegate to the shared
com/typeahead / com/select / com/button-group-button; converting those is the
cross-cutting Phase 11 Selmer sweep, not a single-modal change (Open decision 2).

Quality scorecard (the ratchet)

Cheap to measure (grep -c, wc -l, clj-kondo), recorded before/after each migration in the commit message and in the results table below. No metric may regress for the touched modal without a written exception in gotchas.md. These are directional evidence, not targets to game — always paired with the e2e parity gate.

Heuristics

# Heuristic Measure Target
1 Faked cursor positions (not cursors themselves) grep -cE 'with-cursor|MapCursor\.' re-roots + grep -c 'defn.*-no-cursor' → 0 (top-rooted cursors are fine)
2 Implicit state merges (snapshot/cursor) count merge sites → 0 (forms); explicit put-step only (wizards)
3 Branching complexity clj-kondo, or count cond/condp/case/nested if + max depth net ↓
4 Lines of code wc -l on the modal's file(s) net ↓
5 Reuse / cross-form similarity cookbook components reused; duplicated-block count reuse ↑, dup ↓
6 Route count count routes for the modal → 2 (+1 for add-row)
7 OOB swaps grep -c hx-swap-oob → 0 unless a justified disjoint-region case is documented
8 Attribute consistency mixed :x-/"x-" encodings in migrated template → 0

How to measure (copy/paste)

F=src/clj/auto_ap/ssr/<modal>.clj
echo "LOC                $(wc -l < $F)"
echo "no-cursor twins    $(grep -c 'defn.*-no-cursor' $F)"
echo "faked-cursor roots $(grep -cE 'with-cursor|MapCursor\.' $F)"
echo "snapshot merges    $(grep -c ':multi-form-state :snapshot' $F)"
echo "branch forms       $(grep -cE '\(cond |\(condp |\(case |\(when-not ' $F)"
echo "hx-swap-oob        $(grep -c 'hx-swap-oob' $F)"
echo "mixed string hx-   $(grep -cE '\"hx-[a-z]' $F)"
# route count: count this modal's entries in src/cljc/auto_ap/routes/*.cljc

Results

Each migration appends one row (after-numbers), referencing the before in the diff.

Phase Modal LOC Routes no-cursor twins faked roots snapshot merges OOB mixed hx- cookbook reused / added
1 (baseline) Transaction Edit transaction/edit.clj 1608 ~12 1 2 ~75 0 8 — / seeded 7 entries
2 Transaction Edit transaction/edit.clj 1593 ~5 0 0 0 round-trip 0 8 (shared) location-select / 1 Selmer

Phase 2 progress. Achieved with parity held (swap spec 6/6, transaction-edit spec 8/8, full suite 38 pass / 1 unrelated fail / 0 skip, up from 30/2/7):

  • deleted the dead *-no-cursor* twin (no-cursor 1→0);
  • de-faked the simple-mode cursor (faked roots 2→0) via explicit data + explicit field names (account-field-name) + explicit error lookup — the render-fn rewrite the with-field-default shortcut couldn't do;
  • collapsed the 5 manual-coding operation routes into one edit-form-changed dispatcher (routes ~12→~5; the operations are now pure apply-* fns);
  • fixed a real production bug (:mode → 500 on every advanced manual save);
  • greened transaction-edit.spec.ts (8/8) and matured the skill.

Phase 2 complete. The wizard→plain-form rewrite removed the snapshot round-trip (heuristic 2 → 0) and the first interactive component (location-select) is migrated to a Selmer template (selmer-conventions.md validated). Remaining for later phases: drop the now-thin mm/ModalWizardStep protocol wrappers, and the cross-cutting Phase 11 Selmer sweep of the shared com/typeahead/com/select/com/button-group-button (those shared call sites hold the last 8 mixed @/:-attr offenders; they clear when the shared components move to Selmer — not a single-modal task, per Open decision 2).
