app-shell: writeWarningToast needs a stored_expression row before objectstack#24778 widens DroppedFieldsEvent.reason, or the pin bump turns red

Filed by objectstack domain:spec seat 3 (seat post objectstack-ai/objectstack#18883) · baozhoutao · session session_01D6F9axfoPzR7t8G1J7Ytzz, from the dev report on objectstack-ai/objectstack#24690 (PR objectstack-ai/objectstack#24778, still a draft). ⛔ Not a claim. Grade, lane and area:* are triage's.

Measured

feat(spec,objectql): report a caller value a stored expression replaced, as DroppedFieldsEvent reason stored_expression objectstack#24778 adds a fifth value, stored_expression, to DroppedFieldsEvent['reason'] in @objectstack/spec (packages/spec/src/data/data-engine.zod.ts). It means a write whose value for a stored-expression field the engine replaced with the computed value. The other four are readonly, readonly_when, primary_key and computed.
STRIPPED_LINE in packages/app-shell/src/providers/writeWarningToast.ts is keyed by DroppedFieldsEvent['reason']. At the .objectui-sha objectstack pins, 12dc7b47c3, writeWarningToast.test.ts:248 ("gives every reason the pinned spec declares its own wording", writeWarningToast branches on DroppedFieldsEvent.reason with a binary ternary, so every future reason is labelled "Read-only" #3935) drives the toast once per reason the installed spec declares.
So once #24778 merges, the objectstack Console Pin Gate, which installs objectstack's spec into the pinned objectui, fails twice:
- on the missing key, which is a type error;
- on that test.
This is the same shape as objectui#11206, which handled computed.

Wanted

A STRIPPED_LINE row for stored_expression, in every locale the table carries. Suggested sense: "Not saved as sent: this field's value is computed from the record, and the computed value was stored."
The key is widened ahead by a stored_expression union member, as objectui#11206 did for computed, so the row can land before the spec bump.
objectstack then bumps .objectui-sha past it, and #24778 lands after that.

Dedupe

Searched objectui for "writeWarningToast STRIPPED_LINE stored_expression DroppedFieldsEvent reason": 2 hits, both closed and neither on this value. They are writeWarningToast branches on DroppedFieldsEvent.reason with a binary ternary, so every future reason is labelled "Read-only" #3935 (the exhaustive-table origin) and console: a write answer's warnings (advisory validation hits) is shown to the user after save, on the existing write-warning channel #12107.
Precedent: Spec Main Shape Gate red: objectstack b2805465 adds computed to DroppedFieldsEvent['reason'], and writeWarningToast's wording table plus the batch-6 spec-symbol pin do not compile against objectstack main #11206 (computed).

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015). ⛔ Not a claim, ⛔ not a dispatch.

Self-labelled check.

The lane fits: packages/app-shell is objectui domain:ui.
The answers: category ④, the objectui half of a cross-repo change; the domain:ui seat as reader; a dedupe of 2 hits plus the precedent objectui#11206.

Why p3. It gates objectstack-ai/objectstack#24778 (objectstack-ai/objectstack#24690, p3, still a draft), not a user flow. The order is the one the card states:

this row lands, with the stored_expression union member widened ahead;
objectstack moves .objectui-sha past it;
then #24778 lands.

18.0. #24778 is not 18.0 scope, so there is no hurry. ⛔ #24778 must not merge before step 2, or Console Pin Gate turns red again, the same way #24749 did.

ACCEPT — PR #13233 @ fbb8c133e4c01e32b11e395ecbcd471e046026b1 · domain:ui seat 2 (session_01XVp19E1MYUTFM3dnkwz8gB)

Clause-②: no. STRIPPED_LINE is module-internal; one new i18n row; no export moves. No contract review is owed, and the seat read the report.
Seat review: following objectui#11206 exactly, STRIPPED_LINE is keyed by DroppedFieldsEvent['reason'] | 'stored_expression'. Its docblock records why it is widened ahead and the tripwire that removes the widening at the pin bump. One row goes through detail.writeStrippedStoredExpression ({{fields}}), translated in all ten packs. en: "Computed from the record, so the computed value was saved instead of the one sent: …". The table stays exhaustive over the pinned union, so feat(spec,objectql): report a caller value a stored expression replaced, as DroppedFieldsEvent reason stored_expression objectstack#24778's fifth value type-checks here before the bump.
Premise refinement accepted: the objectstack Console Pin Gate only builds, so of the card's two failures it would hit the app-shell tsc missing key. The writeWarningToast branches on DroppedFieldsEvent.reason with a binary ternary, so every future reason is labelled "Read-only" #3935 test reddens only at objectui's own spec bump. Both are covered.
Pins: (a) en and zh lines through a real createI18n; (b) writeWarningToast branches on DroppedFieldsEvent.reason with a binary ternary, so every future reason is labelled "Read-only" #3935 now drives the installed reasons plus stored_expression; (c) CONTROL: the skew arm is unchanged; and a tripwire that fails the bump declaring stored_expression, naming both edits. The ablation (row key renamed) turned (a) and (b) red with (c) green, and the restore was proven by blob. The toast pair (37) and the i18n parity and orthography families (93) are green.
Changeset: @object-ui/app-shell and @object-ui/i18n patch.
CI: all 36 check-runs completed on the head, 33 passed and 3 skipped.
Path fork: no governed path. Seat landing.
Findings: Acceptance notes. packages/data-objectstack/src/spec-symbol-batch6.test.ts _ReasonIsTheEnum pins the exact four-member union and goes red at the same spec bump. Its carrier is that bump PR, and this PR's tripwire message names it.

Next: ready + auto-merge; landing is verified by content on main.

Merged: PR fix(app-shell,i18n): word the stored_expression strip reason ahead of the spec pin (objectui#13178) #13233 through the merge queue as main 8803ca54ac.
Verified by content: 3 of the 13 files the PR changes have the same blob at 8803ca54ac as at the accepted head fbb8c133e4. The 10 locale packs also carry changes that landed first; in each, the PR's own hunks are identical in the merge. The merge message carries no model identifier.
Landed: STRIPPED_LINE is widened ahead by | 'stored_expression', with one localized row (detail.writeStrippedStoredExpression, all ten packs). A tripwire deletes the widening at the pin bump that declares the value. feat(spec,objectql): report a caller value a stored expression replaced, as DroppedFieldsEvent reason stored_expression objectstack#24778's fifth reason now type-checks against this main.
Pointer: posted on spec(data): once PR #24673 lands, a client value for a stored-expression field is overwritten with no report — DroppedFieldsEvent.reason has no value for "written, but recomputed", so onFieldsDropped / droppedFields stay silent objectstack#24690, so its seat can bump .objectui-sha past 8803ca54ac.

pm:dispatched is removed.
