spec(automation): the $ namespace at every binding door: loop and map iteratorVariable / indexVariable, a screen's idVariable, a declared flow variable's name and an assignment target still bind a $ name a text slot refuses to read

Seam: spec:LoopConfigSchema.iteratorVariable / .indexVariable (control-flow.zod.ts), MapConfigSchema.iteratorVariable / .indexVariable, ScreenConfigSchema.idVariable, AssignmentConfigSchema target keys (builtin-node-config.zod.ts), FlowVariableSchema.name (flow.zod.ts) → runtime: the loop, map, screen and assignment executors' variable binding in @objectstack/service-automation, and the flow's declared-variable seeding

Filing gate: ① class (b), a declared contract violated. reach: a public door answers wrong. FlowSchema.parse (the parse registerFlow, objectstack validate and defineStack share) accepts a $-named binding on these keys, while the same contract's text slots refuse to read it. Found by the dev of PR #22569 (#22502), out_of_scope_findings item 1 of report os-dev-report on #22502. Filed by domain:spec seat 3 (#18883) · session session_01KNKBCRDJCu5tGy3TEbvtrF. ⛔ Not a claim. Triage sets the grade, the lane and the scope.

This is the family close-out card for "the $ names are the flow engine's at every binding door". #22477 closed the read side (the text-slot judge). #22502 (PR #22569) closes two binding keys, outputVariable and try_catch's errorVariable, and its triage scoped it to those two. This card covers every remaining binding key, so the family needs no third single-point card.

The contract text

packages/spec/src/automation/flow-text-slot-template.ts#unboundRootRemedy (about :254–:261 on main fbb065fd4b) tells an author that a variable "the flow binds itself (a declared variable, an assignment target, an outputVariable, a try_catch errorVariable) is named without the $". IAutomationService.resume's INVALID_SIGNAL reserves the $ names for the engine. After PR #22569, two of the four binding kinds the remedy names refuse a $ name. The other two do not, and neither do the iterator and id bindings.

Measured (by the #22502 dev, on the PR #22569 head `ff2832a7bb`)

binding	written	`FlowSchema.parse`
`loop` `iteratorVariable`, with a body `notify` reading `{{ $row.name }}`	`'$row'`	accepted; `NotifyConfigSchema` refuses the read with the drop-the-`$` remedy
a declared flow variable `name`	`'$x'`	accepted
an `assignment` target key	`'$y'`	accepted
a `screen` `idVariable`	`'$id'`	accepted

Not measured: loop indexVariable, map iteratorVariable / indexVariable; the run-time effect of binding over an engine name ($record, $runId, $loopItems). Declared at control-flow.zod.ts:217/:219 and builtin-node-config.zod.ts:849, :1046, :1048 on fbb065fd4b.

The remedy already exists

PR #22569 adds flowBoundVariableNameSchema in packages/spec/src/automation/flow-bound-variable-name.ts. It is package-internal and a regex, so the published JSON Schema carries it as a pattern. Composing it into these keys is the natural fix once #22502 lands. It would be a narrowing (Clause-②: no), owing an ADR-0087 D3 entry like #22502's flow-binding-variable-dollar-name-refused.

Order: after PR #22569 merges (the rule and the D3-entry hot files are there).

Not in scope, noted by the same dev, no carrier: the service-automation executor descriptors (configSchema in crud-nodes.ts, map-node.ts, try-catch-node.ts) still describe these keys as plain strings; engine.ts#buildSubflowResumeSignal's comment calls the reserved-name check a false positive on an oddly named outputVariable.

Dedupe: the open-issue titles of objectstack (116, REST list) matched for iteratorVariable, idVariable, dollar, $ name, binding key, flow variable name → #22502 only, which this card does not repeat. Dedupe words: iteratorVariable dollar name · flow variable name reserved dollar namespace · binding key dollar refused · the $ namespace at every binding door

Triage: first grade, `bug` · `priority:p3` · `domain:spec` · `area:workflow` · `pm:blocked` on #22502. Accepted as the family close-out card

Blocked-by: #22502

Lane: the schemas are in packages/spec (control-flow.zod.ts, builtin-node-config.zod.ts, flow.zod.ts), so domain:spec.
Why p3: the same as spec(automation): try_catch's errorVariable and a node's outputVariable accept a $-named variable that a flow text slot now refuses to read (two doors of one contract disagree after #22477) #22502. FlowSchema.parse accepts a binding whose every read the text slots then refuse, and the refusal is loud and names the remedy. No silent wrong run is measured.
Accepted as the close-out: this is the third card of the family "the $ names are the engine's at every binding door", after spec(automation): a {{ $User.Id }} hole in a flow text slot passes objectstack validate and renders blank with ok: true — the door refuses {$User.Id} loudly but admits its {{ }} spelling silently #22477 and spec(automation): try_catch's errorVariable and a node's outputVariable accept a $-named variable that a flow text slot now refuses to read (two doors of one contract disagree after #22477) #22502. It covers every remaining binding key.
- Enumeration pin: a test that lists every flow binding key from the schemas and asserts that each refuses a $ name. A binding key added later without the rule turns it red.
- ⛔ No third single-point card.
Direction: compose PR fix(spec/automation)!: refuse a $-named outputVariable, and a $-named errorVariable other than $error, at authoring #22569's flowBoundVariableNameSchema into each key: loop and map iteratorVariable / indexVariable, screen idVariable, a declared variable's name, and the assignment target keys.
- It is a narrowing, with Clause-②: no and an ADR-0087 D3 entry, as spec(automation): try_catch's errorVariable and a node's outputVariable accept a $-named variable that a flow text slot now refuses to read (two doors of one contract disagree after #22477) #22502 has.
- Reach goes first.
The two noted strays (the executor configSchema descriptors, and the buildSubflowResumeSignal comment) ride this PR only if it touches those files. Otherwise they stay noted.
Order: behind PR fix(spec/automation)!: refuse a $-named outputVariable, and a $-named errorVariable other than $error, at authoring #22569 (spec(automation): try_catch's errorVariable and a node's outputVariable accept a $-named variable that a flow text slot now refuses to read (two doors of one contract disagree after #22477) #22502, in flight), which brings the rule and the D3-entry hot files.

What landed: flowBoundVariableNameSchema (packages/spec/src/automation/flow-bound-variable-name.ts). It is composed into outputVariable and try_catch's errorVariable, and builtin-node-config.zod.ts now imports it. That is the rule this card composes into every remaining binding key.
The direction stands (6092537456): the family close-out with the enumeration pin over every flow binding key. It is a narrowing with an ADR-0087 D3 entry, and reach goes first.

Not dispatched this round: it waits for #22565 (PR #22609, this seat, in flight) to land. Both are area:workflow and both write a step-18 ADR-0087 D3 entry into packages/spec/src/migrations/registry.ts. #22565's patch round under triage's A′ and S (6095177646) is running now.

Known pitfalls for the claimant:

Compose PR fix(spec/automation)!: refuse a $-named outputVariable, and a $-named errorVariable other than $error, at authoring #22569's flowBoundVariableNameSchema (packages/spec/src/automation/flow-bound-variable-name.ts) into each remaining binding key, as triage's direction 6092537456 says. ⛔ No second rule.
The enumeration pin lists every flow binding key from the schemas, so a key added later without the rule turns it red.
Merge main through scripts/pm/os-regen-merge.sh after automation: a flow CEL expression may name the run user as user, ctx.user or os.user; objectstack validate passes it and the run faults Unknown variable, because flow CEL binds only current_user #22565 lands; its D3 entry and registry hunk land first.
Clause-②: no (a narrowing) with a D3 entry; the contract review at CONTRACT_REVIEW_TIER is owed before enqueue.

The wait on [v18] retire the {var} template dialect in flow assignment slots: refuse at registration with per-spelling remedies (the C half of #11182 ruling D, on the v18 train) #19939 S1 is over. S1 landed as f66fdc7973 (PR feat(spec,service-automation)!: a subflow or map input and a script's inputs are value slots — a CEL envelope per key, the {…} token refused (#19939 pass 4, S1) #22715).
It now waits on lint(flow CEL roots): record is still in ENGINE_BOUND_ROOTS, so objectstack validate passes a record.X read in a flow with no record entrance, which faults at run time once #22642 lands; and two texts describe record as always bound #22677 (domain:spec seat 3, claim 6101461546, in flight).

- The two share packages/spec/src/migrations/registry.ts.

- So their file surfaces are not disjoint.

- Read MapConfigSchema and the loop / map blocks where S1 left them (builtin-node-config.zod.ts, control-flow.zod.ts on f66fdc7973).
- If [Decision] the migration registry registry.ts is the last committed generated aggregate on the ADR-0087 D3 path: keep it and finish B′, or generate it at build #22554 (PR build(spec): the migration registry is generated at build and leaves git #22706) has landed by then, registry.ts is out of git.

File surface (at origin/main 0f77ff5202; stop on breach and explain in the report):

The binding keys, each composing flowBoundVariableNameSchema:
- packages/spec/src/automation/control-flow.zod.ts: LoopConfigSchema iteratorVariable (about :220) and indexVariable (about :222);
- packages/spec/src/automation/builtin-node-config.zod.ts: ScreenConfigSchema.idVariable (about :862), MapConfigSchema iteratorVariable / indexVariable (about :1059 / :1061, where [v18] retire the {var} template dialect in flow assignment slots: refuse at registration with per-spelling remedies (the C half of #11182 ruling D, on the v18 train) #19939 S1 left the block), and the AssignmentConfigSchema target keys (about :1163);
- packages/spec/src/automation/flow.zod.ts: FlowVariableSchema.name (about :218).
The rule's own file: packages/spec/src/automation/flow-bound-variable-name.ts, where its FlowBindingKey vocabulary widens to the new keys.
Pins in packages/spec: the enumeration pin. It lists every flow binding key from the schemas and asserts each refuses a $ name, so a key added later without the rule turns it red.
The narrowing's debts:
- an ADR-0087 D3 entry under packages/spec/src/migrations/entries/semantic/18.*.ts;
- registry.ts regenerated, while it is tracked;
- the generated references, as check:generated decides;
- .changeset/22572-*.md: @objectstack/spec at the level the pre-mode rules give a narrowing (spec(automation): try_catch's errorVariable and a node's outputVariable accept a $-named variable that a flow text slot now refuses to read (two doors of one contract disagree after #22477) #22502's changeset is the precedent), with Clause-②: no (narrowing).
Amended at 2026-10-11T00:00Z (contract review 6103539398 ③ asked for it before enqueue). The surface also covers these items:
- ScreenFieldConfigSchema.name (builtin-node-config.zod.ts): a binding key of the same class, a bounded in-place addition (ACCEPT 6103439893);
- the rule's first-non-blank judgement at outputVariable / errorVariable;
- packages/spec/dropped-refinements.baseline.json: a forced debt for the new refinement site;
- packages/spec/src/migrations/registry.ts.template: since build(spec): the migration registry is generated at build and leaves git #22706 (ed1de8c2db) took registry.ts out of git, the STEP18_RATIONALE fragment lives there, and registry.ts leaves this PR.
The two strays triage named (the service-automation executor configSchema descriptors, and the engine.ts#buildSubflowResumeSignal comment) ride only if this PR already touches those files. Otherwise they stay noted.
Container & model: M, mode:subagent, model: default tier (dispatch-gates --tier: no path-derived mandate). A narrowing of FlowSchema.parse under packages/spec/src/**, so the contract review at CONTRACT_REVIEW_TIER is owed before enqueue.

No S2 claim is open at this stamp.

If build(spec): the migration registry is generated at build and leaves git #22706 has landed, the new D3 entry is an entry file, and any STEP18_RATIONALE fragment goes in registry.ts.template (seat 1's note).
Pitfalls carried (seat 2's note 6096282966): read MapConfigSchema and the loop / map blocks where S1 left them. If S2 or S3 is claimed while this card is in flight, they serialize behind it.

This act moves the card pm:queue → pm:dispatched and assigns zhuangjianguo.

domain:spec seat 3 (#18883) · zhuangjianguo · session session_01KNKBCRDJCu5tGy3TEbvtrF · 2026-10-10T23:45Z · holder of claim 6102582908. Report: os-dev-report on this card. Thread-read: the dev's report.

Checked in the diff, not from the report (net diff against the merge base f59a73c395: 13 files, +771 / −69):

One rule, still package-internal. flowBoundVariableNameSchema serves every binding key, through a BINDING_CLAUSES vocabulary. FlowBindingKey and FLOW_BINDING_KEYS are derived from it, and the enumeration pin reads those. No second rule.
The rule's change:
- The NOT_DOLLAR_LED class is now [^$\s], under a leading ^\s*. A name is judged by its first non-blank character, because the screen and script executors trim before binding.
- Empty and blank names keep the old answer.
The keys composed:
- loop and map iteratorVariable / indexVariable, with their defaults kept;
- ScreenConfigSchema.idVariable;
- FlowVariableSchema.name (flow.zod.ts);
- the assignments map key (propertyNames.pattern).
A new FlowSchema refinement judges every assignment node's targets through flowAssignmentTargets, in the three shapes logic-nodes.ts binds. It refuses at the exact path. No executor contract parses an assignment config, so this is the door.

What the reach measured changes the card's grade reasoning. At the base 0f77ff5202, through an uncommitted engine probe:

a loop iteratorVariable: '$record' made a later screen read the loop's last item as record;
assignments: { $record: 'clobbered' } made it read clobbered;
an object-form screen idVariable: '$id' paused, and the console's resume was refused INVALID_SIGNAL.

So a $ binding was a silent wrong run, not only a loud refusal at the read. After this change registerFlow refuses all six probes. No shipped binding is affected:

FlowSchema.safeParse over the 35 example flows is byte-identical before and after;
an AST scan of examples, platform-objects, dogfood, the rest of the repository and hotcrm 1d7148bf2d found no $-led binding (11 / 11 planted controls found);
the objectui pin found none either.

Measurements accepted:

Suites:
- spec 642 files / 19286 tests (flow-bound-variable-name.test.ts 26 → 115), typecheck green;
- service-automation 185 / 2368;
- lint 135 / 6321;
- the CLI migrate-guidance pin 3 / 3;
- check:generated current.
Ablations, each blob-equal restored:
- dropping MapConfigSchema.indexVariable's rule turns 4 pins red, the discovery pin among them;
- dropping the leading-blank half turns 18 red.
Gates: 114 derived, 112 run, all exit 0. NOT MEASURED, as ordered: dual-build-cjs-loads, check:type-check-debt, and the workspace typecheck lane. check:api-surface is green, and a regex moves no type. The 3 PR-context guards exit 0.

Deviations, put to the contract review:

Two bounded in-place additions in the same defect class:
- ScreenFieldConfigSchema.name: its describe calls it "the flow variable the value binds to", and a $ field was measured to make the screen unsubmittable;
- the first-non-blank judgement at outputVariable / errorVariable too, a further narrowing of spec(automation): try_catch's errorVariable and a node's outputVariable accept a $-named variable that a flow text slot now refuses to read (two doors of one contract disagree after #22477) #22502's still-unreleased rule.
The seat accepts both as owed by the one rule. The review judges the scope.
packages/spec/dropped-refinements.baseline.json: a forced debt (build-schemas.ts refuses the build until the new refinement site is declared). Accepted.
The PR assignee was written with label-write; pr_create could carry it in the same stroke. One write either way. Accepted.
A safety-check refusal on a stray file outside the repository (/sa-suite.pid, from a mis-scoped shell variable). It was not worked around, and it is left for the maintainer. The seat does not remove it.

Out-of-scope findings, noted and not filed:

the service-automation executor configSchema descriptors;
the buildSubflowResumeSignal comment (both are triage's strays, and this PR touches neither file);
content/docs/automation/flows.mdx's paragraph naming only outputVariable / errorVariable;
a body-less legacy loop's iteratorVariable, which its executor never reads.

A contract review at CONTRACT_REVIEW_TIER on af752544fb follows.

Seat order: sync round on PR #22746 before the queue. #22706 took `registry.ts` out of git, so the PR no longer merges

domain:spec seat 3 (#18883) · zhuangjianguo · session session_01KNKBCRDJCu5tGy3TEbvtrF · 2026-10-11T00:01Z · holder of claim 6102582908, amended in place for the review's surface finding. Thread-read: 6103439893.

Where it stands: contract review PASS 6103539398 at af752544fb, with two landing blockers escalated in its ③:

Flag 7: the head does not merge into origin/main (mergeable_state: dirty). PR build(spec): the migration registry is generated at build and leaves git #22706 ([Decision] the migration registry registry.ts is the last committed generated aggregate on the ADR-0087 D3 path: keep it and finish B′, or generate it at build #22554, ed1de8c2db) deleted packages/spec/src/migrations/registry.ts from git and moved STEP18_RATIONALE to registry.ts.template. This PR modifies the deleted file, a modify/delete conflict.
Flag 8: no CI ran on the head. The head commit predates the PR, so no synchronize event fired. The sync push starts CI.

The round:

Recreate the worktree from the remote head af752544fb, and merge origin/main through scripts/pm/os-regen-merge.sh.
Resolve the conflict to build(spec): the migration registry is generated at build and leaves git #22706's model:
- registry.ts leaves this PR, deleted and untracked as main has it;
- the order-93 STEP18_RATIONALE fragment for flow-binding-name-dollar-refused goes into packages/spec/src/migrations/registry.ts.template, sorted by key, before flow-binding-variable-dollar-name-refused;
- the entry file 18.flow-binding-name-dollar-refused.ts stays.
Read how build(spec): the migration registry is generated at build and leaves git #22706 builds registry.ts from the template and the entry files, and regenerate with that tooling.
Verify at the merge head:
- the generation step #22706 introduced, building registry.ts from the template;
- the @objectstack/spec suite and typecheck;
- check:generated;
- node scripts/check-adr-0087-registration.mjs --base origin/main (the D3 id resolves from the entry file);
- the CLI migrate-guidance pin after the CLI closure build;
- the changeset gates.
⛔ No check:type-check-debt --re-measure, and nothing that builds every package.
Push. That push starts CI. Report the new head, git diff --name-only af752544fb NEW-HEAD, and every path the merge resolved by hand.

After the round: the template fragment is hand-written, so the hop is not a pure regeneration. A scoped contract review on the new head follows, covering only the hop.

⛔ Never write a file outside the worktree and your scratchpad. Two stray PID files at the filesystem root (/build-i18n.pid, /sa-suite.pid) came from shell variables set inside a backgrounded chain. Write a PID file into your scratchpad by absolute path.

Seat order: second sync round on PR #22746. `main` now carries the fix for its red `TypeScript Type Check`

domain:spec seat 3 (#18883) · zhuangjianguo · session session_01KNKBCRDJCu5tGy3TEbvtrF · 2026-10-11T06:16Z · holder of claim 6102582908. Thread-read: 6103872839.

Where it stands:

The scoped contract review, round 2: PASS 6106153207 on PR fix(spec/automation)!: refuse a $ name at every remaining flow binding — loop / map iterator and index, screen idVariable and field name, declared variables, assignment targets #22746 at e8c40b9c23. It holds the first sync hop: the template fragment is byte-identical to round 1's, and the other 23 merge paths are main's bytes.
The red TypeScript Type Check is main's (ci(spec): render-projection-diff's base archive lacks the generated registry.ts since #22706, so every merge-queue entry fails Type Check · source gates #22744): the base archive lacked the git-ignored registry.ts. The fix, PR fix(spec): render-projection-diff generates a base's git-ignored migration registry #22750, merged as 052a5e153c. The seat's note 6103889988 said this seat merges main once it landed.

The round:

From the remote head e8c40b9c23, merge origin/main through scripts/pm/os-regen-merge.sh. The review read the 22 commits on main since ed1de8c2db: none touches the PR's 13 paths. Expect a textually clean merge. If any path conflicts or needs a hand edit, stop and report before pushing.
Verify at the merge head:
- the registry generation step, and that the generated registry carries the flow-binding-name-dollar-refused entry;
- packages/spec/src/automation/flow-bound-variable-name.test.ts and step18-rationale-merge.test.ts;
- @objectstack/spec typecheck;
- check:generated;
- node scripts/check-adr-0087-registration.mjs --base origin/main;
- tsx packages/spec/scripts/render-projection-diff.ts --base HEAD^1, the step that was red: report its exit code and its summary line.
⛔ No check:type-check-debt --re-measure, and nothing that builds every package.
Push. Report:
- the new head;
- git diff --name-only e8c40b9c23 NEW-HEAD;
- every path the merge resolved by hand. None is expected.

After the round: a pure hop (the PR's own blobs unchanged, everything else at main's bytes) carries review 6106153207 to the new head, flag 10. The seat checks purity mechanically. Per flags 9 and 11, the 16 source-gates steps that were skipped behind the red, and the first rendered projection diff, are read on the new head's CI before the queue.

⛔ Never write a file outside the worktree and your scratchpad.

Locally HEAD^1 is the branch side e8c40b9, because the merge's first parent is the branch; in CI's merge ref, HEAD^1 is main.

domain:spec seat 3 (#18883) · zhuangjianguo · session session_01KNKBCRDJCu5tGy3TEbvtrF · 2026-10-11T07:33Z · holder of claim 6102582908.

Landed: through the merge queue at 2026-10-11T07:32Z as 9f5eca52b3, a squash with one parent, c74d843997. The queue did not eject it.
The review chain:
- the ACCEPT 6103439893;
- contract review round 1, PASS 6103539398 at af752544fb;
- the first sync order 6103554833, and round 2 scoped to that hop, PASS 6106153207 at e8c40b9c23;
- the second sync order 6106162985, a pure hop to 7b175fa88b checked mechanically;
- the pre-queue record 6106497516.
The CI interruption: the red TypeScript Type Check on e8c40b9c23 was main's (ci(spec): render-projection-diff's base archive lacks the generated registry.ts since #22706, so every merge-queue entry fails Type Check · source gates #22744), as the seat's note 6103889988 said. It cleared when PR fix(spec): render-projection-diff generates a base's git-ignored migration registry #22750 landed and the second sync brought it in.
Content check: all 13 PR paths on 9f5eca52b3 are blob-equal to the reviewed head 7b175fa88b.
What now holds (@objectstack/spec, major in pre mode, Clause-②: no (narrowing)). A name whose first non-blank character is $ is refused at every flow binding position:
- the loop and map iteratorVariable / indexVariable;
- the object-form screen idVariable;
- a screen field's name;
- a declared variable's name;
- every assignment target shape.
The refusal comes from the one rule in flow-bound-variable-name.ts, with the same remedy sentence at every door, and FlowSchema judges the assignment targets. The leading-blank half also reaches outputVariable / errorVariable from spec(automation): try_catch's errorVariable and a node's outputVariable accept a $-named variable that a flow text slot now refuses to read (two doors of one contract disagree after #22477) #22502. The D3 entry flow-binding-name-dollar-refused is registered on 18. Its STEP18_RATIONALE fragment, order 93, is in registry.ts.template.
Carried:
- Next on the area:workflow axis: [v18] retire the {var} template dialect in flow assignment slots: refuse at registration with per-spelling remedies (the C half of #11182 ruling D, on the v18 train) #19939 pass 4 S2, as the S1 landing record 6101473453 orders. This card no longer holds it back.
- Noted, not filed (the PR's acceptance notes):
  - the service-automation executor configSchema descriptors;
  - the buildSubflowResumeSignal comment;
  - content/docs/automation/flows.mdx still names only outputVariable beside errorVariable in its paragraph on where the $ names belong. The paragraph stays true.
Mis-close scan: the squash message carries Fixes #22572 alone, and the merge closed spec(automation): the $ namespace at every binding door: loop and map iteratorVariable / indexVariable, a screen's idVariable, a declared flow variable's name and an assignment target still bind a $ name a text slot refuses to read #22572 alone.

This act removes pm:dispatched; the domain, priority and area labels stay.
