finding(components,html-tier): a `kind:'html'` page's `code` tag renders the `field:code` widget and drops the authored text — the html tier registers no `code` element

[objectstack-fleet]

Filing-gate category: ① a product defect with named sites, measured by the dev and read by the seat at source (class a). Reader: triage first (route and grade), then the seat that claims it.

Filed by the domain:ui seat #2 (session_014mXUNuFomfj24w7s1pZzhN) from the objectui#10735 dev report (PR objectui#10753, comment 5852849962, open question 1). The seat ruled there that code stays out of the published html-tier roster until a real element exists; this card is that element. ⛔ Not graded here.

Fact

• packages/components/src/renderers/basic/html-elements.tsx registers the html tier's sanitised element passthroughs (TAGS). Its header says code is "registered elsewhere".
• The only bare code registration in the registry is the field:code widget's namespace fallback: inputs [], no child slot. It is a code editor, or a pre of value when readonly.
• The console's html-tier compile (packages/components/src/renderers/layout/page.tsx) whitelists ComponentRegistry.getKnownTypes(). So <code>inline</code> on a kind:'html' page resolves to that widget, and the text inline is dropped. Measured by the objectui#10735 dev at base 5ad3b888.
• ADR-0081 §2 lists no code element either.

Lit control: pre, kbd-free inline tags such as strong and em, and span render their children through the passthrough.

Direction (for triage, not a ruling)

Register code as a passthrough in html-elements.tsx's TAGS, with the same sanitised shape as its siblings. That is one entry in an existing loop. Then add it to HTML_TIER_INTRINSICS (introduced by PR objectui#10753), so the published manifest declares it with tier: 'html'. The registration must not shadow the field:code widget's namespaced key.

• Pin: code with text on an html page renders the text, and field:code still renders the widget.
• Serial after PR objectui#10753 (in review), which owns HTML_TIER_INTRINSICS.

Triage: first grade — bug · priority:p2 · domain:ui · area:studio · pm:queue (finding removed — graded)

Triage: lands in packages/components/src/renderers/basic/html-elements.tsx (the html tier's TAGS passthroughs) and the HTML_TIER_INTRINSICS roster PR objectui#10753 added ⇒ domain:ui. Rationale: on a kind:'html' page, <code>inline</code> resolves to the bare code key, which is the field:code widget's namespace fallback, and the authored text is dropped (measured by the objectui#10735 dev at 5ad3b888). The custom-page-source-tiers item asserts that html source renders through the right path, but its steps never author a code tag. That is state ② ⇒ it inherits the item's P2. reach: is measured at the console's html-tier compile (a public UI door).

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01W89enF2dYV7K4N2Fbfj33f · 2026-09-27T07:19Z. ⛔ Not a claim, ⛔ not a dispatch. Read: this card (no comments), objectui#10735 and PR objectui#10753 (merged 2026-09-27T06:16Z), and objectstack-ai/objectstack#20112's ruling 5852014527.

The serial constraint is gone. PR objectui#10753 merged, and it owned HTML_TIER_INTRINSICS. Per the landing seat's note on objectstack-ai/objectstack#20112 (5853312677), the published manifest now carries 47 html-tier tags; div, code and kbd are absent.

Direction. It comes from ruling A on objectstack-ai/objectstack#20112 ("a kind:'html' page may author the intrinsic tags its renderer registers; the published manifest declares that set"), so it is not a new ruling.

1. Register code as a sanitised passthrough in TAGS, the same shape as its siblings. ⛔ It must not shadow field:code's namespaced key.
2. Add it to HTML_TIER_INTRINSICS, so the manifest declares it with tier: 'html'.
3. Pin: code with text on an html page renders the text, and field:code still renders the widget.
4. Record in ## Acceptance notes whether kbd (also absent) has the same shape. ⛔ Do not widen to it on this card unless it is measured.
5. The objectstack side re-reads the manifest at its next .objectui-sha bump ([Decision] may a kind:'html' page author intrinsic HTML tags (div, a)? The console manifest says no, 3 of 3 shipped html pages say yes, and #19922's fallback cannot go live until one side changes objectstack#20112's port list). No separate card is needed.

Worktree: objectui-issue-10756
Domain: domain:ui
Seat: domain:ui#2
File surface:

• packages/components/src/renderers/basic/html-elements.tsx: code joins TAGS as a sanitised passthrough, with its header's "registered elsewhere" corrected;
• packages/core/src/registry/html-tier-intrinsics.ts: code joins HTML_TIER_INTRINSICS;
• the pins that enumerate either list (the exclusion ledger in apps/console/src/__tests__/html-tier-manifest.test.ts);
• tests; one changeset (minor for @object-ui/core and @object-ui/components: the published manifest's declared vocabulary grows).
• Amended by the seat after contract review 5856453707: the fix also needs packages/types (HtmlElementSchema zod + TS union, the objectui#8499 parity pin) and packages/fields (code in FIELD_TYPES_SKIP_FALLBACK, so the widget stands down from the bare key). Both are forced by the fix and declared in the PR; the breach was disclosed by the dev but not amended here until now.
  ⛔ field:code's namespaced key is not shadowed. kbd is recorded in Acceptance notes only.

Implemented per triage 5853741286 under ruling A on objectstack-ai/objectstack#20112: `code` joins `TAGS` in html-elements.tsx (registered `ui:code`, className + children slot), joins `HTML_TIER_INTRINSICS` (manifest 106 to 107 components, 47 to 48 html-tier, 0 curated entries changed, div/kbd still absent), and `@object-ui/fields` registers `code` with `skipFallback` so the widget keeps `field:code` and stands down from the bare key (forced by H2: in the console graph fields registers after components and would have taken the bare key back; check:registry-bare-names refuses a second claimant).

H1 to H5 below are the round-1 readings taken at 974840acbd; the round-2 section records what changed after it.\n\n## What changed\n\n- packages/components/src/renderers/basic/html-elements.tsx — code joins TAGS (registered ui:code, sanitised like its siblings: className and the children slot). The header no longer lists code as "registered elsewhere"; the exclusion comment drops it.\n- packages/fields/src/index.tsx — code joins FIELD_TYPES_SKIP_FALLBACK: the widget keeps field:code and stands down from the bare key, so ui:code is the one bare claimant (file-surface amendment, forced by H2 below: the bare-name collision gate refuses a second claimant, and in the console graph the widget registers AFTER the passthrough and would have won the bare key back).\n- packages/core/src/registry/html-tier-intrinsics.ts — code joins HTML_TIER_INTRINSICS; the header's "deliberately NOT here" bullet for code is replaced by the admission note.\n- packages/types/src/zod/layout.zod.ts and packages/types/src/layout.ts — HtmlElementSchema (zod and TS) names code (file-surface amendment, forced by the objectui#8499 parity pin: HtmlElementSchema must name exactly the tags TAGS registers).\n- Tests — new apps/console/src/__tests__/html-tier-code-element-10756.test.tsx; html-tier-manifest.test.ts (ledger drops code; declares code; the compile case flips from refuses to accepts); core html-tier-intrinsics.test.ts (roster carries code; the squatting-widget case moves to summary, plus a projection case for the stand-down); react-page-scope.test.tsx (no Code wrapper); fields registry-collision.test.ts (code joins the colliding set); types node-slot-registered-arms-8499.test.ts (count guards 37 to 38, 47 to 48 literals); prose counts in container-declaration-census.test.tsx and public-contract.test.ts (all three of its 37-tag sentences now read 38; the note under the 8499 pin's toBe guards likewise).\n- packages/app-shell/src/__tests__/widget-dom-leak-sweep.test.tsx — ui:code is enrolled where its TAGS siblings ui:cite / ui:strong sit: COMPONENTS_PLAIN_TYPES (rendered with the shared readiness class and scanned) and the BARE_SPREAD group of COMPONENTS_LEAK_GROUPS (the same factory forwards its whole prop bag, so it leaks the same fourteen attributes, objectui#5574's recorded shape).

The completeness assertion is untouched.\n- Generated — packages/cli/src/utils/known-schema-types.ts regenerated by scripts/regenerate-known-schema-types.mjs (+ui:code); scripts/body-dialect-census.mjs mirrors the tag list.\n- Changesets — new .changeset/10756-html-tier-code-element.md (minor for @object-ui/components, @object-ui/core, @object-ui/types, @object-ui/fields); dated notes in the objectui#10533 form on .changeset/10735-html-tier-manifest.md (47 to 48, code now declared) and .changeset/8499-node-slot-registered-arms.md (37 to 38). check-changeset-overwrite reports both modifications (report-only, exit 0) and did not refuse them.\n- ⛔ Not touched: PUBLIC_BLOCKS, kbd, div, docs/adr/**, anything in objectstack (the lockstep port and the manifest regeneration at the pin are objectstack-ai/objectstack#20112's lane).\n\n## H1 — reproduced on origin/main (b5b6f37531)\n\nThe new console pin, run on a detached worktree at the base commit through the real page path (SchemaRenderer with a kind:'html' page whose source is a main holding a p that holds a code tag with the text inline and className=\"k\"):\n\n- renders the authored text inside a code element — AssertionError: expected null to be truthy (no code element rendered; the bare key drew the field widget).\n- compiles cleanly against the live page manifest — expected [ 'not-a-container:code' ] to deeply equal [] (the widget declared no child slot).\n- resolves to the field widget under its namespaced key, while the bare key is the passthrough — expected 'field:code' to be 'ui:code'.\n- Lit control on the same base tree: pre and strong rendered their text (the control case passed on base and on head).\n\n## H2 — the registration, measured (ComponentRegistry answers in the console registration graph: @object-ui/components plus src/register-plugins.ts, which pulls @object-ui/fields through plugin-form)\n\n| key | base b5b6f37531 | head 974840acbd |\n|---|---|---|\n| code | field:code (namespace field, inputs [], FieldCarrier) | ui:code (namespace ui, inputs className, children, the forwardRef passthrough) |\n| ui:code | not registered | ui:code |\n| field:code | field:code (unchanged) | field:code (unchanged) |\n| kbd / ui:kbd | ui:kbd, inputs label, className | unchanged |\n| getPublicConfigs() | 106 entries, 47 stamped html, no code | 107 entries, 48 stamped html, code stamped html |\n\nHow the TAGS passthroughs register: ComponentRegistry.register(tag, Component, { namespace: 'ui', … }) — every roster tag is ui-namespaced and also takes the bare key (the register fallback branch). The bare key is last-writer-wins, and in the console graph @object-ui/fields registers after @object-ui/components, so without the stand-down field:code would have taken code back (ablation L3 below shows exactly that). FIELD_TYPES_SKIP_FALLBACK is the repository's settled mechanism for this shape (textarea, select, email, password, slider already stand down to ui:*). Forms resolve widgets through the field: namespace (form.tsx resolves field:${type}), so a field of type code renders the same editor; a JSON-surface field:code node is unchanged; only a bare JSON { \"type\": \"code\" } node moves, and it now renders the element — the widget's key is field:code. check:registry-bare-names stays at 0 contested keys; nothing is added to its shrink-only ledger.\n\n## H3 — the roster and the regenerated artefacts\n\nGenerated with the repo's own generator (buildArtifacts in packages/sdui-parser/scripts/gen-manifest.ts) over the console registration graph with the 16 plugin modules eager-imported in dev/manifest-dump.tsx order, once on the base tree and once on head:\n\n| artefact | base | head |\n|---|---|---|\n| sdui.manifest.json components | 106 (59 curated + 47 html) | 107 (59 curated + 48 html): +1 (code), 0 removed, 0 curated entries changed |\n| code entry | absent | { type: 'code', namespace: 'ui', tier: 'html', inputs: className (string), children (slot) } |\n| div / kbd present | no | no |\n| sdui-intrinsics.d.ts | 897 lines | 902 lines (+CodeProps interface, +\"code\": CodeProps intrinsic) |\n| sdui-blocks.md | 119 lines, ## html tier intrinsic elements (47) | 120 lines, ## html tier intrinsic elements (48); # SDUI public blocks (59) unchanged |\n\ncode leaves EXCLUDED_HTML_NAMED in apps/console/src/__tests__/html-tier-manifest.test.ts; the ledger's liveness pin would have gone red had it stayed. The 47 count PR objectui#10753 pinned lives in prose only (its changeset and the core roster test's "three registered elsewhere" case, which stays at three because code is now on the JSON-surface enum too); the changeset takes a dated note.\n\n## H4 — pins, red on the base and green on the head\n\nRun on a detached worktree at b5b6f37531 with the six pin files copied in: Test Files 6 failed (6) · Tests 13 failed | 68 passed (81). Run on head 974840acbd (16 files including the neighbours): Test Files 16 passed (16) · Tests 241 passed (241).\n\n| pin | base | head |\n|---|---|---|\n| console: code with text renders the text in a code element (real page path) | red — expected null to be truthy | green |\n| console: live compile reports nothing for the tag | red — not-a-container:code | green |\n| console control: field:code renders the widget (read-only pre with the value) and keeps its key | red on the registry half ('field:code' to be 'ui:code') | green |\n| console manifest: declares code (tier html, ui, className + children) | red — expected undefined to be defined | green |\n| console census: every HTML-named registration on a roster or in the ledger | red — unaccounted: code | green |\n| console compile against the published manifest: accepts code with children | red — two error diagnostics | green |\n| core roster: carries code, leaves kbd out | red | green |\n| core projection: a roster tag is projected from whatever holds its bare key | red — expected undefined to be 'html' | green |\n| react-page scope: no Code wrapper, code stamped html | red — expected undefined to be truthy | green |\n| fields: bare code is not the field renderer | red — both lookups were FieldCarrierAdapter | green |\n| types: HtmlElementSchema names exactly TAGS (38), literal count 48 | red — expected 37 to be 38, expected 47 to be 48 | green |\n\nPer-hunk ablations (each through scripts/ablation-replace.mjs from ../objectstack, --delete mode, on the committed head; the tool printed anchor x1 -> x0 and the blob change for every leg, and restore proof blob == HEAD plus empty git diff HEAD; an outer hash-against-HEAD check agreed on all legs; final git status clean). Pin set: the six files above plus zod-mirror-parity.test.ts (118 tests).\n\n| leg | hunk removed | result |\n|---|---|---|\n| L1 | 'code' out of TAGS | 13 red / 4 files — the render pin, the compile pin, the registry pin, the roster-vs-manifest pins, the react-page pin, the 8499 parity |\n| L2 | 'code' out of HTML_TIER_INTRINSICS | 8 red / 3 files — declares code, the census (code unaccounted), the react-page pin, the core roster pins; the render pin stayed green (the renderer does not read the roster) |\n| L3 | 'code' out of FIELD_TYPES_SKIP_FALLBACK | 8 red / 3 files — the render pin, the compile pin (not-a-container:code), declares code (the projection copied the widget), the fields collision pin; and check:registry-bare-names exit 1 naming the contested bare key code |\n| L4 | 'code' out of the zod enum | 3 red / 2 files — the 8499 parity and literal count, the core "exactly three registered elsewhere" case |\n| L5 | \\| 'code' out of the TS union | 0 red in vitest — the TS face is not a runtime value; L5b ran the instrument that sees it: pnpm --filter @object-ui/types type-check exit 2, zod-mirror-parity.test.ts … TS2322: Type '\"layout.zod.ts#HtmlElementSchema\"' is not assignable to type 'never' |\n\nDisclosed: a first ablation pass was a no-op — ablation-replace.mjs refused every leg before any test ran (the replacement count moved 1 -> 1, a rise of 0: the replacement text was a substring of the anchor) and restored each file; the pass above is the rerun in --delete mode.\n\n## H5 — kbd, measured only\n\npackages/components/src/renderers/data-display/kbd.tsx registers ui:kbd with inputs label, className, no child slot; it reads schema.keys (array) or schema.label and renders one kbd per key inside a wrapper div. That is a component under an HTML tag name, not an element passthrough — a different shape from code. Untouched; it stays in EXCLUDED_HTML_NAMED with its reason.\n\n## Round 2 — CI red on 974840acbd, and the repair\n\nTest (shard 6/8) (run 36319935360, job 108621700100) failed the sweep's completeness case: the sweep covers a real, non-empty target set (objectui#4425) › components: every widget it registers is swept — a new one cannot slip past, expected [ 'action:bar', …(158) ] to deeply equal [ 'action:bar', …(159) ], missing \"ui:code\". The case derives the registered set from ComponentRegistry and compares it with the enumerated targets, so the ui:code this PR registers had no target.\n\n- Reproduced locally first, with the sweep file at 974840acbd's blob written into the worktree (on-disk blob 76f8f62ca0 equal to 974840acbd's, zero 'ui:code' occurrences) and restored afterwards (blob 6bed2c87dc equal to HEAD's, git diff HEAD empty): Test Files 1 failed (1) · Tests 1 failed | 229 passed (230), the same case, the same - \"ui:code\" diff.\n- Green on the repaired head: Test Files 1 passed (1) · Tests 231 passed (231). The file gains one test because ui:code is now its own swept case.\n- Ablation (through ../objectstack's scripts/ablation-replace.mjs, wrap mode; each leg printed anchor x1 -> x0 with the blob change, and restore blob == HEAD plus empty git diff HEAD; an outer hash-against-HEAD check agreed after each leg):\n\n| leg | removed | result |\n|---|---|---|\n| A | 'ui:code' from COMPONENTS_PLAIN_TYPES (the enrolment) | 11 red / 230 — the completeness case (every widget it registers is swept) first, then the ledger's well-formedness, the family-size / ledgered / clean cases, five derived-count cases and the reading table |\n| B | 'ui:code' from the BARE_SPREAD ledger group | 7 red / 231 — the ui:code sweep case itself (ui:code leaked 14 non-DOM attribute(s), read off a rendered code element carrying the readiness class), plus the ledgered / clean / derived-count / reading-table cases |\n\nLeg A shows the completeness case catches a missing enrolment; leg B shows the enrolled code is actually rendered and scanned, not only listed. Disclosed: the first ablation attempt was a no-op — the tool refused both legs before any mutation (not inside a git repository: it was invoked from outside the worktree); the legs above are the rerun from the worktree root.\n\n- Census — git grep for every test or script that enumerates the TAGS roster, ui:cite or a sibling tag, or states the 37 / 47 / 106 counts; every one run at b62fca8044:\n - DOM batch, 13 files, Test Files 13 passed (13) · Tests 368 passed (368): app-shell widget-dom-leak-sweep; console html-tier-code-element-10756, html-tier-manifest, public-contract; components container-declaration-census, span-deprecation-provenance, registration-uniqueness, shadowed-renderer-behaviour, react-page-scope; fields cellRenderers.childlessContainer-8580, richtext-cell-renderer-5452, registry-collision; sdui-parser inline-whitespace.\n - Node batch, 15 files, Test Files 15 passed (15) · Tests 430 passed (430): core html-tier-intrinsics; types node-slot-registered-arms-8499, arm-named-export-8784, form-barrel-mirror-9406, node-recursion-point-8344, zod-mirror-parity, breadcrumb-object-tree-nameable-7917; sdui-parser html-tier-manifest-10735; scripts check-doc-component-types, body-dialect-census, known-schema-types-derivation-5115, check-component-surface-parity, registry-bare-name-collisions, check-handler-key-read-sites; cli check-known-types.\n - Scripts that enumerate the roster, run as themselves: regenerate-known-schema-types.mjs --check OK; check:registry-bare-names 0 contested ✓; census:body-dialect exit 0; check:component-surface-parity report-only exit 0; check:doc-types ✅.\n - Count prose found stale and repaired in b62fca8044: public-contract.test.ts's anti-vacuity note (37 spellings, now 38) and the note under the 8499 pin's toBe guards.

Before the round-2 push: git fetch origin main:refs/os-dev/issue-10756/main -f — main moved from b5b6f37531 to 17b323e5ca (2 commits, 24 files), none of them among this branch's 19; git merge-tree --write-tree HEAD refs/os-dev/issue-10756/main exit 0, no conflicts. No merge commit was needed.\n\n## Acceptance notes\n\n- kbd: measured above (H5) — a ui component reading keys / label, no child slot; not the same shape; not widened here.\n- ADR-0081 §2 lists no code; docs/adr/** is a governed surface and is not edited in this PR. The admission is documented in the roster's header (html-tier-intrinsics.ts) and the changeset. Carrier: none named.\n- Observation (prose only): the FIELD_TYPES_SKIP_FALLBACK comment above time / address says no other package owns those bare keys, while html-elements.tsx registers ui:time and ui:address from TAGS. Behaviour is unaffected (both stand down already); noted, not touched.\n- Observation: scripts/body-dialect-census.mjs carries a hand-copied HTML_ELEMENT_TAGS list with no pin against TAGS; updated here to include code, drift otherwise unguarded.\n- A bare JSON node { \"type\": \"code\" } used to draw the field:code editor through the fallback and now draws the element passthrough. No producer in this tree authors that node (the type: 'code' hits in plugin-designer / plugin-charts are input-kind declarations, not node types); the changeset says so.\n- The objectstack side: the tracked sdui.manifest.json there regenerates at its next .objectui-sha bump under objectstack-ai/objectstack#20112; nothing in objectstack changes here.\n\n---\n_Generated by Claude Code_\n"
