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)"

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
2-final	Transaction Edit (full Selmer + wizard removed)	1548	5	0	0	0	0	0	full sc/* lib / ~30 partials
3	Transaction Bulk Code transaction/bulk_code.clj	506 (was 420 — see exception)	3	0	0	0	0	0†	reused all of Phase-2's sc/* lib + account-typeahead*/location-select* + edit-modal/transitioner chrome / added sc/select

† The one "hx-..." string hit is a response-header map ({"hx-trigger" "refreshTable, reset-selection"}), not a mixed attribute encoding. mm coupling 19→0, wizard records 3→0, step-params 10→0 (the 2 hits are comments), Hiccup-in-render → 0 except the shared com/success-modal (heuristic-9 exception, as in Phase 2).

New heuristics introduced at 2-final (full Selmer)

#	Heuristic	Measure	Target
9	Hiccup HTML tags in the render path	grep -cE '\[:(div|span|p|a|button|input|h[1-6]|ul|li|label|select|option|t(able|head|body|r|d|h)|form|svg|template)' over the modal's render fns	→ 0 (success-modal confirmation dialogs may keep the shared Hiccup component)
10	mm wizard coupling	grep -c 'mm/' the modal file + grep -c 'defrecord.*Wizard|ModalWizardStep'	→ 0 for a single-step modal

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).

Phase 2-final — full Selmer + wizard removed. Every component the modal renders through was ported to a Selmer partial under resources/templates/components/ with a thin Clojure wrapper in auto-ap.ssr.components.selmer (sc/*); the modal's own structure lives under resources/templates/transaction-edit/. The mm wizard abstraction (EditWizard/LinksStep records, MultiStepFormState, step-params[...] field names, wrap-wizard/wrap-decode-multi-form-state middleware) was deleted — there was only ever one step, so it was pure overhead. Result: heuristic 8 (mixed hx-) and 9 (Hiccup in render) and 10 (mm coupling) all → 0; the edit-wizard-navigate route is gone (routes 5). Parity held: swap spec 6/6, transaction-edit spec 8/8, full suite 38 pass / 1 pre-existing unrelated fail (serial, fresh seed). The only Hiccup left in the file is the post-save com/success-modal confirmation dialogs (terminal, shared component — out of the form's render path). See form-vs-wizard.md (drop-the- wizard test), selmer-conventions.md (composition mechanics), and gotchas.md (stray-field decode leak; jetty reload staleness).

Phase 3 — Transaction Bulk Code (first cold apply of the mature skill). Single-step form wearing a full wizard costume (BulkCodeWizard/AccountsStep, MultiStepFormState, the step-params[...] prefix, the old find * location swap). Migrated to a plain form by mirroring Phase 2 — and it was mostly reuse: the entire sc/* Selmer component library, account-typeahead*/location-select*, and the edit-modal/transitioner chrome were imported wholesale; the only new shared component was sc/select (the status dropdown — location-select.html generalized). Parity held: bulk-code spec 13/13, full suite 39/39 (up from the Phase-2 baseline of 38–39). mm coupling 19→0, snapshot merges 4→0, wizard records 3→0, routes 4→3 (open / submit / form-changed — the per-op new-account + vendor-changed routes folded into one form-changed op dispatcher), the location swap moved off find * onto explicit #account-location-<index> + hx-select.

The one regression — LOC 420→506 (documented exception, see gotchas.md). Unlike edit (whose wizard held real custom code), bulk-code's wizard was a thin shell that delegated almost everything to mm/* defaults (default-render-step, default-render-wizard, submit-handler, open-wizard-handler). Ripping the wizard out moves that previously-shared plumbing into the file as explicit render/decode/submit/handler code. The trade is intended: every other heuristic improved and the modal is now self-contained and wizard-free. New patterns added to the cookbook: the selection-as-ids[] round-trip (resolve the non-editable selection to a concrete id vector at open, ride it in hidden fields — the bulk analog of edit's single db/id), and the :id-keyed vendor typeahead (a value-bound hidden must be keyed or its posted value goes stale across a whole-form swap).
