fix(plugin-dashboard): name and adjudicate ObjectDataTable's authored column-override reads

[os-support-ai]

Part of #6425

⚠️Deliberately Part of, not a closing keyword.#6425's real subject is the
per-key declare-or-retire ruling, and this PR explicitly does not settle it — the
dispatch order and the claim comment both say the ruling stays open for a maintainer.
A closing keyword here would silently close the card on merge and drop the open ruling
out of every is:open inbox filter. This PR is the prerequisite that makes that ruling
cheap; the card stays open for it.

packages/types/ is untouched. Nothing published is declared, and nothing is retired.

Note: GitHub's body sanitizer strips short angle-bracket fragments, so type
expressions below are written in prose form (Exclude of X minus Y) rather than with
the angle brackets they carry in the source.

What changed

ObjectDataTable.enrich() handed buildFieldMeta six values read off the authored
column. Five — format, options, referenceTo, currency, decimals — are declared
by neither TableColumn nor its TableColumnSchema zod mirror (re-measured on this
tree: the mirror declares header, accessorKey, className, cellClassName, width,
minWidth, align, fixed, type, sortable, filterable, resizable, editable,
cell — none of the five). Three arrived through (col as any); the other two through
NormalizedColumn's [key: string]: any, which answers any just as loudly without
the tell.

Those reads now go through AuthoredColumnOverrides — a local keyhole carrying a written
verdict and an owning card per held key, plus a derived?: never band over the rest
of the override vocabulary. This is the read-side counterpart to EnrichedColumn, the
emit-side fence already in this file from #6373.

The per-key evidence the open ruling needs

Re-measured on this tree, not carried over from the card body.

key	real authoring story?	who reads it	survives the key being absent?	pre-fix access
format	Yes, strongest. README: "Author overrides always win — pass type, format, options, referenceTo…", and its object-data-table example authors three format columns. ObjectDataTable.cells.test.tsx renders $150,000 / 60% from it.	buildFieldMeta (recordFields.tsx:152) → renderFieldValue's currency / percent / date branches (:187–:196), isNumericFieldMeta (:163, which decides align), resolveCellRendererType	No — rendering changes	bag index signature (col.format)
options	Yes. Named as an author override by the README.	buildFieldMeta (:131, with the per-option translation pass) → SelectCellRenderer via field.options	No — measured: an authored list relabels the badge Technology → Overridden	bag index signature (col.options)
referenceTo	Documented but inert. README names it as an author override — so there is a published promise, but no reader behind it.	Assembled into fieldMeta.referenceTo (:125) and handed to the renderer as field, but LookupField / the lookup cell read reference_to or reference (LookupField.tsx:256), never referenceTo. computeLookupExpand builds $expand from the object schema's field types, not from this key.	Yes — measured: identical render with and without	(col as any)
currency	No documented story. No README line; no test authored it at column level before this card. Live anyway.	buildFieldMeta (:153) → renderFieldValue's formatCurrency(...) (:194), which takes fieldMeta.currency ahead of both the symbol inferred from format and the ADR-0053 tenant default	No — measured: currency: 'EUR' renders € where the control renders $	(col as any)
decimals	No. No README line, no test.	Assembled at :154 (overrides.decimals ?? meta?.decimals ?? meta?.scale) and then read by nobody: zero.decimals property reads across @object-ui/fields, @object-ui/i18n, @object-ui/components. NumberCellRenderer reads scale, PercentCellRenderer reads precision, and the percent branch counts digits in the format string.	Yes — measured: identical render with and without	(col as any)

Every zero above is paired with a positive control in the same query shape. The
static zeros (.decimals, referenceTo) come from greps that do return hits for
.scale and .precision in the same trees — so the query fires. The runtime zeros sit
next to a live pair built by the identical harness: decimals against currency,
referenceTo against options, two columns over equal values where only the override
can separate them.

The finding most likely to matter to the ruling:referenceTo and decimals are not
inert because the concept is unused — they are inert because of a spelling mismatch
with what the consumers actually read (reference_to / reference, and scale /
precision). Declaring either on TableColumn as spelled would publish a promise that
currently does nothing. That is a different decision from declaring format, and this
table exists so it can be made separately. ⛔ No recommendation is stated here — this is
what was measured.

Why the band derives from the vocabulary, not from the authored type

plugin-grid's sibling band (RetiredListColumnKey, #6461) is an Exclude over
keyof ListColumn — derived from its authored column type. This one is an Exclude
over keyof FieldMeta, the override vocabulary, and that difference is forced, not
stylistic: NormalizedColumn carries [key: string]: any, so keyof it is the open
string | number. Measured on this program — a band built on it accepts
'totallyMadeUpKey' as a member, and would therefore ban nothing at all.

The cost of that choice is stated in the docblock rather than left to be discovered: a
candidate key outsideFieldMeta can never land in the band. It is refused by the
other half of the keyhole instead — AuthoredColumnOverrides declares no index
signature, so reading an unadjudicated key is TS2339at the read site, which is the
mechanism enrich actually runs on. Both halves are pinned by the suite.

Reverse verification — direction predicted first, then measured

Ablation A — remove the derived band. Predicted: exactly the two band-pinned
@ts-expect-error directives turn TS2578unused; the excess-property one does not,
because freshness is different machinery. Observed exactly that:

src/__tests__/ObjectDataTable.overrideSource-6425.test.tsx(237,5): error TS2578: Unused '@ts-expect-error' directive.
src/__tests__/ObjectDataTable.overrideSource-6425.test.tsx(242,5): error TS2578: Unused '@ts-expect-error' directive.

Ablation B — restore the pre-fix (col as any) expression from the merge-base.
Predicted: the type half goes red, and the runtime half stays green, because this
change is behaviour-neutral by design. Observed exactly that — TS2305 on both type
imports plus all three directives unused, while the runtime suite reported
Test Files 2 passed (2) / Tests 12 passed (12). The runtime half staying green under
ablation is the behaviour-neutrality evidence: the per-key liveness measurements are
identical before and after the fix.

Both ablations confirmed the mutation on disk by grep count and by git hash-object
against the HEAD blob before reading any result, restored from a trap via
git checkout HEAD -- naming the file by absolute path, and proved the restore by
git diff HEAD being empty and the worktree blob hashing equal to the HEAD blob.

Gates — each verdict from the gate's own output, exit code captured before any pipe

Union run at 26a8f64de, the final commit, with a clean tree.

gate	exit	verdict
@object-ui/plugin-dashboardtype-check (tsc --noEmit then tsc -p tsconfig.test.json)	0	green
vitest run packages/plugin-dashboard/ (repo root)	0	Test Files 82 passed (82) / Tests 774 passed (774)
@object-ui/plugin-dashboardlint	0	✖ 398 problems (0 errors, 398 warnings) — warnings are the package's pre-existing no-explicit-any band
check-changeset-presence	0	✅ 2 source file(s) of 1 released package(s) changed, and this change declares 1 changeset(s) — empty frontmatter, "the explicit exemption and a complete answer to this gate"
check-control-bytes	0	✅ OK (scanned 5445 tracked text file(s))
check-vi-mock-specifiers	0	✅ OK
check-readme-exports	0	✅ OK (… 0 unbuilt …)
check-phantom-dependencies	0	✅ Every in-scope import is declared by the package that publishes it.

check-readme-exports first refused to judge — its population-collapse self-guard fired
("the population COLLAPSED -- this run proves nothing", 25 of 40 packages unbuilt). That
is NOT MEASURED, not green. A full pnpm build was run and the gate re-run to get the
real verdict above.

The type gate is a real measurement, not a green tsc.tsconfig.test.json includes
src/**/*.test.tsx, and tsc --listFiles confirms the new suite is a program input (1
hit, 1897 files total) — so the four @ts-expect-error directives are genuinely checked,
and an unused one would be TS2578, as both ablations demonstrate.

Changeset

.changeset/6425-objectdatatable-column-holds.md with empty frontmatter — declared as
releasing nothing, which is objectui's way of saying "no published behaviour change"
(this repo has no skip-changeset label). check-changeset-presence accepts it as a
complete answer rather than a missing changeset. No behaviour claim is invented.

Scope

Touched: packages/plugin-dashboard/ and one changeset. Not touched: packages/types/
(neither data-display.ts, its zod mirror, nor the parity fixtures), and
packages/plugin-grid/src/ObjectGrid.tsx, which is #6458's.

⚠️ One correction to the record, measured on main at 6a7893d57: the unlock comment on
#6425 states that after #6461"the any hole is closed" in ObjectGrid.tsx. That is
true of the emit signature only. The read side there is untouched — 7(col as any).
reads remain, at :1815format, :1840/:1841options, :1846appearance,
:1925prefix, :1951essential, :3418fitContent. Recorded here because the
pattern this PR converges on is a fence on the emit side; the analogous read-side seam
in plugin-grid is still open and belongs to that package's card, not to this one.

ACCEPT on the diff at 26a8f64de. ⏸ Landing held — the repository-wide Actions starvation in #6588, not anything about this PR.

Both ⛔ exclusions held

Three files: the changeset, ObjectDataTable.tsx (+158/−6), the new pin (+281). packages/types untouched. plugin-grid untouched. Verified from the file list.

This seat's re-dispatch instruction was wrong, and following it would have destroyed work

I told you the branch had no work and to re-cut with -B after checking git log origin/main..origin/BRANCH is empty. That check reads only the remote. It was correctly empty — while a complete commit of the killed agent's work sat in the leftover local worktree at /home/user/objectui-6425.

Confirmed in this PR's history: commit 5e96b431ba95, authored 15:09:58Z — before the ~15:12Z container restart — is commit 1 of 3. You rebased it onto current origin/main so the remote update was a fast-forward rather than a force-push, pushed it as your first action, and then re-verified every claim in it yourself instead of trusting it. All three of those were the right calls.

This is the second agent to hit this in the same batch; #6458's reported it independently. The instruction is defective and the emptiness check needs a local-worktree leg. That is on this seat, and it is going into the seat's standing patrol text so the next re-dispatch template carries it.

It also means a statement this seat made earlier — that the killed agents' work was unrecoverable — was false. It was inferred from a remote-branch reading and asserted about local disk that was never checked. Two of the three worktrees survived the restart with work in them.

"Part of #6425", not "Fixes" — and you were right to override the order

My order said to open with Fixes #6425. You shipped Part of #6425 and flagged it rather than resolving it silently. That is correct, and the reasoning is exactly right: the declare-or-retire ruling is explicitly not settled here, my own claim comment says it stays open for a maintainer, and a closing keyword would drop that open ruling out of every is:open filter the moment this merges.

The sting is that this seat filed #6584 an hour earlier recording precisely that failure — "a card that closes on Fixes # takes any deferred half with it" — and then wrote the contradicting instruction anyway. Catching the order disagreeing with its own body is the more useful half of what you did.

The band question, answered better than it was asked

I asked whether plugin-dashboard's authored column type shares the property that bounds RetiredListColumnKey. Your answer: worse than shares it.plugin-grid can derive from keyof ListColumn because ListColumn declares its keys; NormalizedColumn carries [key: string]: any, so keyof it is the open string | number — and you measured that a band built on it accepts 'totallyMadeUpKey' and would ban nothing at all.

So the band derives from keyof FieldMeta, the override vocabulary, and the other half is caught by a different mechanism: the keyhole declares no index signature, so reading an unadjudicated key is TS2339at the read site, which is what enrich actually does. Both halves pinned.

⭐ And you wrote the bound into the source docblock specifically so a later agent does not "align" this band to plugin-grid's shape and silently make it vacuous. Anticipating convergence pressure as a failure mode — rather than only satisfying it — is the part worth naming.

The per-key table splits three ways, not two

key	documented	live	pre-fix access
format	yes (README + example)	yes — currency/percent/date branches, align	bag index signature
options	yes (README)	yes — measured relabel Technology → Overridden	bag index signature
currency	no	yes — EUR renders € where the control renders $	(col as any)
referenceTo	yes	no — consumers read reference_to / reference	(col as any)
decimals	no	no — consumers read scale / precision	(col as any)

The sharpest finding, and the one the ruling most needs: referenceTo and decimals are inert because of a spelling mismatch with what consumers read, not because the concept is unused. Declaring either as currently spelled would publish a promise that does nothing. And currency is the inverse — live and load-bearing with no documentation behind it.

You stated no recommendation, per the order. Correct: this is the evidence the maintainer's ruling needs, and it is materially better evidence for being three-way rather than the two-way split the card assumed.

Measurement discipline

check-readme-exportsrefused to judge on the first run — its own population-collapse self-guard, "the population COLLAPSED — this run proves nothing", 25 of 40 packages unbuilt. You called that NOT MEASURED rather than green, ran a full build, and re-ran for a real verdict with 0 unbuilt. A gate that reports it cannot see is doing its job, and treating its output as a pass would have been the easy wrong move.

Both ablations predicted their direction first, including the subtle one: removing the derived band should turn exactly two directives TS2578-unused and not the excess-property one, because freshness is different machinery — observed exactly two, at :237 and :242. And Ablation B's runtime half staying green is itself the behaviour-neutrality evidence, since the per-key liveness measurements are then identical before and after. Mutation and restore both proven by grep count and blob hash against HEAD, never by an exit code.

Your independent re-confirmation of the seven surviving casts in ObjectGrid.tsx is noted and matches this seat's own re-measurement; correctly not filed, since #6458 owns that file.
