[v18] flow text slots: read ADR-0032 §3's {{ }} delimiter instead of single-brace {token} (notify title/message and the other flow string slots), converting only what renders the same

Governing text: ADR-0032 (Accepted) Decision 3, "One delimiter, {{ }}; single { } deleted." (docs/adr/0032-unified-expression-layer.md:78).

Filed by the triage seat (objectstack-wide, seat post #6015, session_01AavokzJ5DndAwitDXvKy4U). ⛔ Not a claim. This executes an accepted ADR; it is not a decision card. Under .claude/skills/pm-dispatch/SKILL.md 〈升级与决策〉, the protocol is the baseline: code that disagrees with it is aligned to it, and an option that conflicts with the governing text is not a decision card. Amending §3 instead is the maintainer's to ask for, on its own card.

What disagrees today (read on `main` `aa71c4d9d1`)

Two template delimiters ship side by side:
- {{ }}: the formula template engine (packages/formula/src/template-engine.ts:31, HOLE_RE) and the messaging renderer (packages/services/service-messaging/src/template-renderer.ts:40).
- { }: flow node text slots. The flow interpolator reads single-brace tokens (packages/services/service-automation/src/builtin/template.ts:359). The notify node's title / message say so (builtin/notify-node.ts:190). The lint rule flow-double-brace-interpolation flags {{ }} on flow node values (packages/lint/src/lint-flow-patterns.ts:1719: "Double-brace {{ }} is the formula/template-field dialect, not flow node values").
The spec already types these slots: since PR feat(spec): notify title/message are template slots — bare string or tmpl envelope #22063, a notify node's title / message are template-typed slots (spec: a notify node's refused title / message is told to write '{{record.name}}', the spelling the build's flow-double-brace-interpolation rule then flags on the same node and the notify renderer does not resolve #22081). So the slot names the dialect whose delimiter §3 fixes, and the executor reads the other one.
Authors follow the shipped spelling. git grep -c (a pattern count, not a parse):
- hotcrm main: 69 single-brace {record.…} tokens in 12 *.flow.ts files, and 0 {{;
- this repo's examples: 46 in 2 files, and 0 {{.
The cost §3 names is live. { } collides with CEL map literals, and an author who meets both dialects mixes them. spec: a notify node's refused title / message is told to write '{{record.name}}', the spelling the build's flow-double-brace-interpolation rule then flags on the same node and the notify renderer does not resolve #22081 is that mix: a refusal prescribed {{record.name}} for a slot whose lint flags it.

Scope

Flow node text slots: notify title / message, and every other flow string slot the single-brace interpolator reads. Enumerate them first.
⛔ Not the value slots. fields.* and assignment values leave the template dialect for CEL 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 (maintainer ruling D on [Deferred by ruling] Unify flow field-expression assignment onto the CEL engine — the B half of the #11060 ruling, awaiting maintainer appetite #11182).
⛔ Not titleFormat: it is deprecated toward nameField (ADR-0079).

Measure first

Enumerate the slots the single-brace interpolator reads, and the sites per slot in this repo and in hotcrm.
Lossless check, per ADR-0087 D2: render each measured site with today's interpolator and with the template engine (null, a number, a date, a nested path, an unknown path). Only spellings that render the same may convert automatically.

Direction

The text slots read {{ }} through the formula template engine (§3: holes are paths plus whitelisted formatters).
An ADR-0087 conversion rewrites {x} → {{ x }} only where step 2 measured it lossless. A spelling that renders differently is refused at registration with its remedy, ⛔ never converted.
The conversion entry lives in packages/spec, so it goes through the spec seat (lanes/services.md:11).
flow-double-brace-interpolation flips: it flags single-brace on these slots. The notify-node description and spec: a notify node's refused title / message is told to write '{{record.name}}', the spelling the build's flow-double-brace-interpolation rule then flags on the same node and the notify renderer does not resolve #22081's refusal text prescribe {{ }}.

Pins

A notify title Hello {{ record.name }} renders the name.
A stored Hello {record.name} loads converted (when lossless) and renders the same text.
Control: {{ }} pasted into a CEL predicate still fails to parse loudly (§3's last sentence).

Sequencing

Serial with [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: both edit the flow interpolation module (builtin/template.ts). Claim after it lands, or declare the overlap.
Foreseen follow-up: the objectui Studio editors for these slots insert the v18 spelling. Triage reads that surface and files the objectui card in its next objectui round, keyed on the install face.

Clause-②: yes: a published authoring contract changes on the v18 line.

The judge is flow-text-slot-template.ts, which shares the interpolator grammar with the value-slot judge through a new internal flow-template-token.ts. The two doors also compile the holes. Measurement falsified H2: no spelling renders the same on every input (a Date renders JSON-quoted under 17.x; a whole-slot object or array in screen/end text renders [object Object]; {$error.message} had no hole spelling). Per the stop condition, NO D2 conversion is registered and every spelling is refused with its remedy; the D3 entry is flow-text-slot-single-brace-refused. @objectstack/formula's hole path now admits $, so {{ $error.message }} is a hole (landed outside the claim's surface, at the producer).

🔁 Patch round 1: PR #22315 at `11bdb8c966`. One declaration line; the seat's own claim line was wrong. Same claim, same branch, the same dev

domain:spec seat 2 (#18549) · os-sales · session session_01DhTqaEHqPVSVnAkjG3jywn · 2026-10-08T15:23Z · holder of claim 6059160333, on the dev report 6063121790.

Correction to this seat's claim 6059160333, its Clause-②: line. The claim's parenthetical promised "a lossless D2 conversion", and the dev's H2 measurement falsified it: no spelling renders the same on every input (a Date value, a whole-slot object or array), so no conversion is registered and every single-brace text-slot token is refused. The delivered diff narrows one surface (the single-brace text tokens) and widens others ({{ }} holes now render in the five text slots; @objectstack/formula's hole path admits $). In scripts/pm/clause2-line.mjs's fixed spelling that is Clause-②: yes (narrowing). The claim's line now reads, by this correction:

Clause-②: yes (narrowing)

The seat writes the claim comment's and the PR body's lines in this act; the changeset's line is the patch round's one edit.

The report's open question (A or B): answered by the ruling the dispatch carried, not a decision. ADR-0087 D2 converts a spelling only where it renders the same, and "a spelling that renders differently is refused at registration with its remedy, ⛔ never converted". The measurement found none that renders the same on every input, so A (refuse every single-brace token with its hole spelling, the D3 entry only) is what the ruling already says. B would need the maintainer to accept a rendering change, and nothing pulls for it.

Read on GitHub and on the branch, otherwise in order:

Form: draft, base main, first line Fixes #22110, the only closing keyword in the body.
Scope: 51 files, +1666 / −374 against dc4a5c630; 0 governed paths; under the 5000-line threshold. Beyond the claim, accepted on the producer rule: packages/formula/src/template-engine.ts (a $ variable gets a hole spelling, so {$error.message} has a remedy; domain:engine, declared on [PM seat] domain:engine — 🟢 os-project-manager #6367 in this act), the new flow-text-slot-template.ts / flow-template-token.ts (one grammar shared with the value-slot judge), the screen and end contracts, the engine's end render point and screen-nodes.ts, the dogfood fixtures and ledger entry, common-patterns.mdx and the service-automation README.
The ratchet line, reviewed: dropped-refinements.baseline.json grows by one site (679 → 680), automation/ScreenConfig root, the superRefine that judges title / description. The ledger is hand-edited so that a new gap is a reviewed line: accepted here as the refusal's only spelling that carries a remedy; the contract review judges it too.
H4 as built: flow-double-brace-interpolation exempts the text slots instead of flipping, because the build door already refuses the single brace at error and a second rule would double-report. Accepted.
Gates: 119 derived, 119 run, --ran reconciled at 0 NOT-MEASURED; the narrowed spec run (four src dirs) is declared, and CI runs the whole suite.

The patch round (one edit): .changeset/22110-flow-text-slot-double-brace.md, the line Clause-②: yes → Clause-②: yes (narrowing). Re-run check-changeset-no-major (with the live PR payload via --event, as #22149's dev did), check-adr-0087-registration and check-empty-changeset on the new head. ⛔ No other change.

Out of scope, one line each:

skills/objectstack-automation/SKILL.md (:108–:109, :224–:236) and evals/flows-triggers-approvals.json:17 teach the single-brace text spelling this PR refuses · this seat files the Tier H card when this PR lands (finding(skills): objectstack-automation SKILL.md teaches {token} values in create_record / update_record fields that PR #22259 (#19939 pass 1) refuses, and its money-rounding sample is CEL integer division #22260, the value-slot sibling, is closed).
The Studio editors for these slots insert the single brace · carrier: triage's objectui round, as the card names.
hotcrm's 69 single-brace text tokens (per the card) are refused at registration once this ships · carrier: the repo:hotcrm seat, named on this seat's post (this container cannot reach hotcrm).
AutomationEngine.celScope nests a flat dotted key into an existing variable's object; validate-flow-template-paths skips a hole with a formatter; the service-automation README's stale field-value row · Acceptance notes (carrier: none).

After the push: the ACCEPT, then the contract review at CONTRACT_REVIEW_TIER on the new head, then landing.

The declaration agrees in all three carriers: the claim, the PR body (written by this seat, read back byte-identical) and the changeset. The dev's check-changeset-no-major --event on the live PR payload reads "this PR declares clause-② yes (narrowing)"; check-adr-0087-registration reads the changeset [major+BREAKING+clause-②-narrowing], registered flow-text-slot-single-brace-refused; check-empty-changeset exits 0. major for spec, service-automation and lint is pre mode's grade on main (.changeset/pre.json, tag next), as 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's pass 1.
The rest of the review stands as written in 6063190355: scope (51 files, +1666 / −374, 0 governed), the producer-side @objectstack/formula edit (declared on [PM seat] domain:engine — 🟢 os-project-manager #6367), the one reviewed ratchet line (dropped-refinements 679 → 680, automation/ScreenConfig root), H4 as an exemption, the open question answered A by ADR-0087 D2, and the out-of-scope lines.
CI: the red TypeScript Type Check on 11bdb8c966 is the aggregate over jobs the new push cancelled, on a head that is no longer current; not re-run. On 73b682847b at this stamp: 18 check-runs so far, 10 success, 1 skipped, 7 in_progress, none failed.

Landing to-do: the ## Contract review at CONTRACT_REVIEW_TIER on 73b682847b, from an isolated at-tier subagent, dispatched now → every check green → check-governed-merges --pr 22315 → the generated-artifact drift reading against main → pr_ready and auto-merge → after the merge, the content check and the Tier H skills/objectstack-automation card.

Contract review FAIL on PR #22315 at `73b682847b`: patch round 2 (two fixes, one in-round lint fix, one wording fix), then a fresh review

domain:spec seat 2 (#18549) · os-sales · session session_01DhTqaEHqPVSVnAkjG3jywn · 2026-10-08T15:48Z · holder of claim 6059160333. This amends that claim's file surface. ⛔ Not a new claim.

The record is 6063558021 on PR #22315 (served at CONTRACT_REVIEW_TIER, isolated subagent, Head-sha 73b682847b). The seat re-read both FAIL reasons at that head; both hold:

packages/spec/src/shared/expression.zod.ts (about :402–:403): the TemplateExpressionInputSchema docblock this diff edits still ends "{{var}} on this schema's slots, {var} on a notify node's", a few lines under the bullet the diff rewrote to say a notify title / message reads {{var}} only. It ships in the spec tarball's .d.ts.
packages/spec/src/automation/flow-text-slot-template.ts singleBraceTokens (about :127–:130) drops a token only when BOTH neighbours are braces. So Total {{ amount } keeps { amount } as a single-brace path token, and doubled prescribes Total {{{ amount }}: a wrong correct-form, printed at every door.

Patch round 2 (same dev, same branch):

(1) Drop the {var} clause from that docblock; the sentence names {{var}} for the notify slots too.
(2) A token that touches exactly one brace is an unbalanced hole, not a single-brace token: the refusal does not prescribe a rewrite for it, and the compile step (validateExpression('template', …)) reports it. Pin both shapes (Total {{ amount } and Total { amount }}) at the spec function and at one door, asserting the refusal's code and path, and that no three-brace text appears in the message.
(3) In-round, not a card: the review's escalated flag. packages/lint/src/validate-flow-template-paths.ts templateRefsIn reads /\{([^{}]+)\}/g and skips a body that is not a bare dotted path, so {{ record.subjcet | upper }} draws no finding. Before this PR a text slot had no formatter syntax, so this PR creates the blind spot. It also makes false the rule's docblock "Mirrors the runtime interpolator's token grammar (service-automation builtin/template.ts)", because this PR deletes that interpolator. The four conditions for an adjacent in-place fix hold: same defect class (reading a template token's path), mechanical (the path before an optional | formatter), no other claim (the 11 open PRs' file lists, read at this stamp), and the same gate family (packages/lint, already major in this PR). Fix it: a {{ path | formatter… }} hole's path is judged like a bare one. Correct that docblock. Pin a misspelt path under a formatter (finding), and a correct one (none), in validate-flow-template-paths.test.ts, which this PR already edits.
(4) Wording: the changeset and the PR body name renderTextSlot as if it were public. It is package-internal (service-automation exports . only, and builtin/template.ts is not re-exported). Describe the behaviour, not the function, or mark it internal. The changeset ships as CHANGELOG.md.

Claim file surface, revised: adds packages/lint/src/validate-flow-template-paths.ts (templateRefsIn and its docblock only). Everything else above is already in the PR's file list.

Not changed: the rest of the review holds as 6063558021 records it (the three node-contract narrowings, the doors, the $ widening in @objectstack/formula, the 679 → 680 ratchet line, no D2 conversion, Clause-②: yes (narrowing) across the three carriers). The Tier H residue (skills/objectstack-automation/SKILL.md :108–:109, :224–:236, evals/flows-triggers-approvals.json:17) is still this seat's card when the PR lands.

Next: the dev's report → the seat's review of the round's diff → a fresh ## Contract review at CONTRACT_REVIEW_TIER on the new head (a FAIL's fix is re-reviewed, not waved through) → every check green → the landing to-do in 6063281763.

✅ ACCEPT: PR #22315 at `0b094026d` (patch round 2 delivered). A fresh contract review is dispatched

domain:spec seat 2 (#18549) · os-sales · session session_01DhTqaEHqPVSVnAkjG3jywn · 2026-10-08T17:18Z · holder of claim 6059160333 (surface revised in 6063702421), on the dev report 6065199188.

Checked on the branch, not taken from the report (e899a2c81..0b094026d, 8 files, +130 / −10):

(1) The TemplateExpressionInputSchema docblock's closing sentence names {{var}} for the notify slots too.
(2) singleBraceTokens keeps a token only when neither neighbour is a brace. A one-brace hole is left to the compile step, pinned at the spec function (no refusal) and at the objectstack validate door (invalid-template at config.title, no three-brace text).
(3) templateRefsIn cuts the path before | only inside a {{ }} hole, so a single-brace token's | stays unjudged as before. Its docblock describes both dialects.
(4) The changeset, sentences checked: "one renderer inside @objectstack/service-automation (package-internal; the package's public exports do not change)", and "a hole that does not compile fails the node with a guard refusal, which a fault edge does not route". The second sentence was verified at engine.ts about :11146, where isGuardRefusal(execErr) leaves faultEdge undefined and rethrows.
Ablations: one per code fix, each red on its named pin and restored to the HEAD blob.
Gates: dispatch-gates --ran reads 119 derived, 119 run, 0 NOT-MEASURED. The changeset gates read yes (narrowing) and registered flow-text-slot-single-brace-refused.

Two corrections to the seat's own order, made here in public:

6063702421 said this PR "deletes that interpolator". It deletes only interpolateText. interpolate / interpolateString still render the value-like positions, so the dev's docblock rightly describes both dialects rather than dropping one.
That order asked the dev to edit the PR body, a write the role file reserves to the seat (the same error as on build: a script node's undeclared config key passes objectstack validate, compile and registerFlow, then fails every run — the key half of #21898's class (subflow by reading) #21982). The dev refused and proposed the edits. This seat wrote them, read back identical:
- renderTextSlot is marked package-internal;
- a ## Patch round 2 section is added;
- the formatter observation is updated.

Out of scope, one line each:

A {{ }} hole whose path uses bracket indexing ({{ rows[0].subjcet }}) is still skipped by validate-flow-template-paths. The template engine's hole grammar ^[\w$.[\]]+$ admits it. No writer or os validate reach has been measured, so it is not a card. It is in the PR's Acceptance notes, carrier: the next PR to edit packages/lint/src/validate-flow-template-paths.ts.

CI at this stamp on 0b094026d: 34 success, 4 skipped, and 4 still running after this seat's body edit. Before that edit, the head read 33 success, 2 skipped, 0 failed.

Landing to-do: a fresh ## Contract review at CONTRACT_REVIEW_TIER on 0b094026d, from an isolated at-tier subagent, dispatched now. A FAIL's fix is re-reviewed, not waved through. Then every check green → check-governed-merges --pr 22315 → the generated-artifact drift reading against main → pr_ready and auto-merge. After the merge: the content check and the Tier H card for skills/objectstack-automation/SKILL.md (:108–:109, :224–:236) and evals/flows-triggers-approvals.json:17.

Contract review FAIL on PR #22315 at `0b094026d`: patch round 3 (two docblocks, the canon pin widened, the bracket-path lint gap fixed in-round)

domain:spec seat 2 (#18549) · os-sales · session session_01DhTqaEHqPVSVnAkjG3jywn · 2026-10-08T17:32Z · holder of claim 6059160333. ⛔ Not a new claim.

The record is 6065484352 (whole-PR review at 0b094026d). It finds the earlier FAIL's two reasons resolved and the formatter fix right. It fails on two more sentences of the same class in the file this diff edits. The seat re-read both at the head, and both hold. The seat's own ACCEPT 6065269979 missed them.

①.17: packages/spec/src/shared/expression.zod.ts about :512–:515, the exported tmpl helper's docblock. It still says a notify node's title / message "are rendered by the flow interpolator, which reads single braces only", that {{record.x}} "keeps its outer braces", and that flow-double-brace-interpolation flags it. All three claims are false at this head, and the bullet prescribes the refused form.
①.18: the same file about :297–:299, the TYPED_EXPRESSION_SOURCE_REQUIRED docblock: "The notify node's title / message, rendered by the flow interpolator, prescribe {record.name}". At this head NOTIFY_TEMPLATE_PLACEHOLDER is {{ record.name }}.

The escalated flag, and why it is fixed here rather than filed. templateRefsIn skips a hole whose path uses bracket indexing ({{ rows[0].subjcet }}). The seat's ACCEPT left it in Acceptance notes for lack of a measured reach. The record supplies the reach, and the seat confirmed it at the head: this PR's own changeset and content/docs/automation/flows.mdx (about :295) teach {{ rows[0].subject }} as a text-slot spelling. In 17.x rows[0].x did not resolve in a text slot, so this PR creates the gap, exactly as it created the formatter one that round 2 fixed in-round. The same four conditions hold: same function, mechanical, no other claim, same gate family. So it is fixed here, and no card is filed.

Patch round 3 (same dev, same branch):

(1) Rewrite the tmpl bullet: since protocol 18 a notify node's title / message read {{record.x}} too, and a single-brace token there is refused at every door.
(2) Rewrite the TYPED_EXPRESSION_SOURCE_REQUIRED sentence: the notify slots take their own sentences so they can name the key, and they prescribe the same {{ }} hole.
(3) Widen packages/spec/src/shared/template-expression-input-canon.test.ts with the same predicate to the docblocks above export function tmpl and export const TYPED_EXPRESSION_SOURCE_REQUIRED, so this file's canon is held as one set. Then sweep packages/spec/src/** for any other docblock or .describe() that prescribes {var} for a notify, screen or end text slot, and fix it the same way or name it.
(4) packages/lint/src/validate-flow-template-paths.ts templateRefsIn: inside a {{ }} hole, normalise [n] to .n before the dotted-path test. Pin a misspelt bracket path under a hole (finding) and a correct one (none).
An ablation per code fix, as in round 2.
The PR body's Acceptance-notes line about bracket paths is rewritten by the seat after your report. ⛔ Do not edit the PR body.

Not taken: the record's optional note to run the compile step even after the judge refuses (it does not change a verdict).

Next: the dev's report → the seat's check of the round's diff → a fresh contract review at CONTRACT_REVIEW_TIER → every check green → landing. The skills Tier H card is still owed at landing. The record notes it can be opened now; the seat files it at landing, as planned, so it cites the merged commit.

"tests": "Readings at 5bfa9ae, the merged head, after pnpm turbo run build --concurrency=2 (73/73 exit 0, under the lock): spec src/shared src/automation src/migrations: 74 files, 2239 passed. lint whole suite: 128 files, 5853 passed. service-automation, 8 files, 108 passed: the text-slot tests (text-slot-template, notify-template-slots, notify-node, end-node-refused-outcome) plus #22319's engine tests (config-unknown-keys, decision-branch-expression-absent, nested-region-parity, predicate-slot-blank). typecheck: spec exit 0 ('check:test-typecheck: OK … 52 file(s) / 246 error(s) / 135 pinned signature(s) held'); lint exit 0 ('… 2 file(s) / 6 error(s) / 2 pinned signature(s) held', the passing reading the CI note asked for); service-automation exit 0. pnpm --filter @objectstack/spec run check:generated: '✓ All 15 generated artifacts are up to date'. Earlier readings: at c673c86 the spec suite went red in expression-dialect-docs.pin.test.ts (2 tests, an existing pin of the old tmpl relation; see deviations). At b5d3cd5: spec src/shared src/automation 70 files / 2024 passed; lint 128 / 5853; typecheck spec and lint OK; check:generated 15/15. Ablations, all through node scripts/ablation-replace.mjs WRAP mode. Each landed its mutation (anchor 1→0, blob changed on disk), ran the pin, restored, and proved blob == HEAD with git diff HEAD empty. Fix 1 at c673c86: expression.zod.ts 2fb7b4000ba2→53c8bdbd4435. The canon pin 'export function tmpl › prescribes no single-brace placeholder for a notify slot — only a sentence that refuses one names it' went red (1 failed / 5 passed). Fix 1 again at b5d3cd5, with both pins: same mutation, and both 'tmpl' pins went red (2 failed / 10 passed), the canon pin above and expression-dialect-docs.pin.test.ts › lists the notify slots with the double-brace renderers, the single brace there as refused, and no {record.x}-only bullet. Fix 2 at c673c86: 2fb7b4000ba2→360b0d554d17. 'export const TYPED_EXPRESSION_SOURCE_REQUIRED › prescribes no single-brace placeholder…' went red (1 failed / 5 passed). Fix 4 at c673c86: the normalisation line deleted, validate-flow-template-paths.ts 8b447a926d3b→3520073d10b7. 'judges a bracket-indexed path in a {{ }} hole like its dotted form' went red (1 failed / 63 passed). CI repro at c673c86: the cast reverted, test file a7b253898cad→15c56f9bd318. pnpm --filter @objectstack/lint run typecheck exit 1 with 'src/validate-flow-template-paths.test.ts: 1 type error(s) in a file the ledger does not cover'; restored. The gate's summary line does not print the TS code, so none is quoted. Item 3 is a pin, and the fix-1 and fix-2 ablations are what redden it. The round's five source and test files are byte-identical at b5d3cd5 and 5bfa9ae (blobs 2fb7b4000ba2, 2c776882c1eb, 2bb0e89c7304, 8b447a926d3b, a7b253898cad), so these ablations hold at the merged head. Merge proof. git range-diff 28bff18d0..b5d3cd532 3599fef12..HEAD: commits 1–16 are '=', and 17 is the new regeneration commit 5bfa9ae. PR-file diff: the file set is the same 54 files before and after, and the sorted +/- line multiset of git diff -U0 28bff18d0 b5d3cd532 equals that of git diff -U0 3599fef12 HEAD (2261 lines, empty interdiff). For every file both sides touched (flows.mdx, validate-expressions.test.ts, engine.ts, api-surface and export-origins automation.json, registry.ts), every line either side added is present at HEAD (missing 0 on each side). Test Core (2/6) timing, src/integration/connector-author-shape.test.ts, the it at :194. It was run at 5bfa9ae (H) and at main 3599fef (M, a detached probe worktree, removed afterwards), interleaved H M H M H M in one locked run, load average 10–24. The it: H 19274 / 25222 / 26948 ms, M 23523 / 27609 / 24922 ms (means H 23.8 s, M 25.3 s). File wall: H 30.4 / 40.1 / 43.8 s, M 38.2 / 41.0 / 38.8 s. Deterministic counts from tsc --extendedDiagnostics over the test's exact three probes (two fences plus the harness self-test) with its compiler options. H: 588 files, 155870 TS lines, 280586 types, 970144 instantiations. M: 586 files, 155565 lines, 280505 types, 969975 instantiations, a +0.03% type delta. Check time: H 14.57 / 18.05 s, M 14.39 / 17.68 s. Each run reports only the harness's expected TS2739. Verdict: the head is within ~10% of main (here it is not slower).

Seat check of patch round 3 on PR #22315 at `5bfa9ae1f`: ACCEPT. Next: a fresh contract review on this head

domain:spec seat 2 (#18549) · os-sales · session session_01DhTqaEHqPVSVnAkjG3jywn · 2026-10-08T20:29Z · holder of claim 6059160333. ⛔ Not a new claim.

The report is 6068392390. The seat read the round's own commits, not the merge: 171cea002, c673c8635, b5d3cd532 and the regeneration 5bfa9ae1f.

(1)/(2) packages/spec/src/shared/expression.zod.ts:
- The tmpl bullet now says that since protocol 18 a notify node's title / message read {{record.x}} and that a single brace is refused at every door.
- The TYPED_EXPRESSION_SOURCE_REQUIRED sentence now says the notify slots take their own sentences so they can name the key, and that they prescribe the same {{ }} hole.
- Both sentences named by review 6065484352 (①.17, ①.18) are true at this head.
(3) The canon pin holds the three docblocks with one predicate. b5d3cd532 moves the older expression-dialect-docs.pin.test.ts relation, which item (1) had to turn red, to the protocol-18 one. The sweep's near-misses (context-tokens.zod.ts {recordId}, the 17.x fixtures in conversions/registry.ts, io-node-config.zod.ts's value-like positions) all describe value-like positions or history, so their text is still true.
(4) In a hole, templateRefsIn reads [i] as .i before the dotted-path test. That is the same normalisation as the formula engine's resolvePath. A quoted index stays unjudged, as an arithmetic token. It has one finding pin and one no-finding pin. c673c8635 is the typed spread that fixed the Type Check · workspace red.
The merge (0788b58e1, origin/main 3599fef12, via os-regen-merge.sh):
- The only conflict was engine.ts's import block, resolved as the union.
- 5bfa9ae1f restores main's builtinNodeConfigKeysJudged in api-surface / export-origins, which the driver had dropped.
- Range-diff shows = for commits 1–16. The line multiset is unchanged across the merge.
- The STEP18_RATIONALE entry stays at order 89, tied with fix(spec,service-automation)!: an undeclared config key on 10 more builtin node types is refused at the build doors; one judge per type #22319's. The docblock allows ties, so it is not changed.
CI at this head (note 6067723298):
- Test Core (6/6) is finding(ci): the shard-timings dataset rests on ONE scheduled run, and records @objectstack/spec at 1134.86 s against 1573–1651 s executed — #16468's 25%-headroom ceilings built on it would red every PR that runs spec #22014's timing drift.
- Test Core (2/6) is connector-author-shape.test.ts:194 at its 60 s budget, the margin hourly full run: red on main (CI) #22292 records on main. Measured interleaved, head 19.3 / 25.2 / 26.9 s vs main 23.5 / 27.6 / 24.9 s, with +0.03% tsc instantiations, so this PR does not make it slower.
- The next push re-runs both; the seat brings main in after the review if no round follows.
PR body: rewritten by the seat at this head. The Acceptance-notes bracket line now records the round-3 fix, and a ## Patch round 3 section carries the readings.

Owed at landing, unchanged: a Tier H card for skills/objectstack-automation/SKILL.md (:108–:109, :224–:236) and evals/flows-triggers-approvals.json:17.

Next: a fresh ## Contract review at CONTRACT_REVIEW_TIER on 5bfa9ae1f, from an isolated subagent → every check green → the landing to-do in 6063281763.

Two merges of origin/main, both through scripts/pm/os-regen-merge.sh (never a rebase, never a force-push): (1) f84cd82d2 = bff973d87 + main ca135dcc4 (39 incoming commits incl. #22380, #22392, #22393, #22406, #22368); (2) on the seat's note, 4e275f15d = f84cd82d2 + main 3054516ef (4 incoming commits incl. 27a8b33de, the #22416 fix; git merge-base --is-ancestor 27a8b33de HEAD exits 0). CONFLICTED FILES: none in either merge (zero conflict markers, the script's step 1 completed with exit 0 and step 3 had nothing left to commit). Files edited on BOTH sides in merge 1, each auto-merged by git with disjoint hunks and read after the merge: packages/spec/src/migrations/registry.ts (the branch's step-18 fragment and D3 entry, main's two new fragments, two new D3 entries and a rewording of the flow-builtin-node-config try_catch text); packages/lint/src/validate-expressions.ts (branch: the flow text-slot pass, flowNodeTextSlotSources and textSlotTemplateRefusal; main #22392: the select-option visibleWhen root and member verdicts, OPTION_VISIBLE_WHEN_BOUND_ROOTS and OPTION_VISIBLE_WHEN_BOUND_MEMBERS; both kept); packages/lint/src/validate-expressions.test.ts; packages/services/service-automation/src/engine.ts (main changed comments and the runAs warn text only); packages/services/service-automation/README.md; examples/app-showcase/src/automation/flows/index.ts (main changed a comment on InboundTaskWebhookFlow only); content/docs/automation/flows.mdx. Merge 2 overlapped no file the branch edits. No same-logic semantic choice arose, so nothing was escalated. STEP18_RATIONALE is the union of both sides in id order: 107 fragments, 0 out of order. flow-text-slot-single-brace-refused (branch) sits between flow-script-subflow-config-undeclared-keys-refused and flow-value-slot-template-dialect-refused. sys-view-definition-retired and try-catch-and-retry-policy-undeclared-keys-refused (main) sit at their sorted positions. GENERATED ARTIFACTS: os-regen step 2 took main's side of nothing, because no os-regen path changed on both sides. It kept the branch's bytes of the four paths only the branch changed (references builtin-node-config.mdx and io-node-config.mdx, api-surface/automation.json, export-origins/automation.json). gen:migration-registry, gen:spec-changes and gen:upgrade-guide each regenerated byte-identical: git status was empty afterwards, so no regeneration commit was needed. check:generated reports 15/15 current.

It is one merge of origin/main 05c7c3fa3 (7 incoming commits, incl. 46692c118 = #22427), made in a fresh worktree objectstack-issue-22110-m2 on the remote head 4e275f15d through scripts/pm/os-regen-merge.sh (never a rebase, never a force-push). CONFLICTED FILE, the only one: packages/lint/src/validate-expressions.test.ts, one hunk. It is not inside any test case. It is the PLUMBING receiver-excuse set of the receiver-scan test (its assertion: every scanned receiver is either tabled or in PLUMBING). Both sides appended to the end of that set at the same spot. OURS (branch, #22110): a 4-line comment plus 'slot', the spec text-slot locator's local, whose keys are path, label and source. THEIRS (main, #22394 via #22427): a 4-line comment plus 'declaredUserMembers', 'boundUserMembers', 'listedNames', 'tickedNames', 'membersRead', the EvalUser member-list locals. RESOLUTION: the verbatim union, the branch's block then main's, with no character of either side edited. The set's members are order-free, and no assertion changed. Neither side's setup had to change to fit the other: each entry excuses only its own side's local, and dropping either would turn the scan red for that side. Proof of the union: 0 lines either side added (vs merge base 3054516ef) are missing from the merged file, and 0 test titles of either parent are missing. The merged file has 297 titles, the same as main's 297, which contain the branch's 290: the branch adds no case to this file. CASES KEPT FROM MAIN (#22427), every one, in the describe 'a per-option visibleWhen member of the acting user the option check does not bind is refused (#22394)': (1) it.each 'refuses %s at error, located at the option, naming the member and the members that are bound'; (2) 'the roles refusal names positions in the spelling the author wrote, and that replacement passes and evaluates'; (3) 'CONTROL: every bound member under every spelling, a grant check, and a record field named like a refused member pass'; (4) 'POSITIVE CONTROL: the same current_user.email read in an object action predicate, a surface the refusal does not judge, is not refused'; (5) 'judges every member spelling as one read: optional, indexed and has()'; (6) 'one finding per option: an unbound root, then a namespace member, then members in SCOPE_ROOTS and name order'; (7) 'every receiver the option check binds judges its members against a declared source'. Also kept: main's five PLUMBING entries above. KEPT FROM THE BRANCH: its 'slot' PLUMBING entry, the branch's only edit to this file. The branch's text-slot cases live in packages/lint/src/validate-expressions.text-slot.test.ts, which main did not touch (0 lines changed), so all 5 are kept unchanged: (1) refuses a single-brace token in a notify title / message and a screen title / description, at error, with the hole spelling; (2) compiles a slot with no single-brace token: logic, an unknown formatter or an unbalanced hole is an error; (3) reports a hole touching exactly one brace as the compile step's unbalanced hole, with no three-brace rewrite; (4) passes holes, formatters and a dollar-named variable, and every single-brace slot that is not text; (5) judges an end message too, for a stack handed to validateStackExpressions with no parse in front of it. AUTO-MERGED, both sides edited, disjoint hunks, read after the merge: packages/lint/src/validate-expressions.ts (main #22427 extends the option visibleWhen verdicts, around 1115 to 1417 and 2261; the branch's text-slot pass and imports are intact); content/docs/automation/flows.mdx (main adds a 403 row and rewords the trigger route's outcome table, outside every section the branch edits); examples/app-showcase/src/automation/flows/index.ts (main re-types InquiryPurgeFlow from autolaunched to screen, a flow type with no text-slot node). GENERATED: on the script's rerun, step 2 took main's side of nothing and kept the branch's bytes of the same four paths as before, and step 3 had nothing to commit. No regeneration commit was needed (see tests). The merge commit carries the model-free trailer pair. Worktree removed after the report.",
  "tests": "At NEW HEAD ce4f6519f, after a full workspace build (turbo build --concurrency=2 --filter=!@objectstack/docs: 72/72 tasks, lock VERDICT command-exit 0). Lint unit tier in full, under scripts/pm/os-verify-lock.sh (pnpm --filter @objectstack/lint test): 129 test files passed, 5904 tests passed, lock VERDICT command-exit 0. That is 13 more than the 5891 at 4e275f15d: #22427's cases, with its it.each expanded. Lint typecheck (tsc --noEmit plus check:test-typecheck): VERDICT command-exit 0. Gates: node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack derived 120 commands at ce4f6519f over 54 paths (+1854/-407) vs merge base 05c7c3fa3. Both the command list and the delta are identical to round 2's, so the PR's delta against main is unchanged by this merge. All 120 were run with exit codes captured before any pipe, and all 120 exited 0, including check:pm-dispatch-gates (2011 cases pass) and spec check:generated. Then --ran answered: 120 derived, 120 run, 0 NOT-MEASURED (a derived zero), 0 UNRUN. check:nul-bytes OK. NOT MEASURED, extra beyond the asked scope: a verbose targeted run of the two test files above hit lock queue-timeout exit 99 twice. Both files are inside the green full-tier run. Spec, formula and service-automation tiers were not re-run this round. #22427 touched none of them, and main's spec edit (src/data/hook.zod.ts) is outside the branch's files. They are covered by the derived gates and CI. Declared to CI as before: Test Core shards and their timing-drift step, Dogfood Regression Gate, Dogfood Verify CLI, Temporal Conformance, Build Core and Build Docs, the workspace type-check lanes.",

Landed: PR feat(spec)!: flow text slots read the {{ }} delimiter, refusing a single-brace token with its hole spelling (#22110) #22315 merged through the merge queue at 2026-10-09T09:41Z as 2b61f2d9d. It has one parent, 4f4c4ed81, and is an ancestor of origin/main. There was no queue ejection. Fixes closed this card.
Content check against the reviewed head ce4f6519f (contract review PASS 6077952132, after the merge rounds 6076389514 / 6077810372):
- 50 of the 54 PR files on 2b61f2d9d are blob-equal to that head.
- The other four also moved on main, and the queue merged both sides. Every line this PR adds is present on 2b61f2d9d:
  - lint/src/validate-expressions.ts: 21 of 21;
  - validate-expressions.test.ts: 5 of 5;
  - migrations/registry.ts: 53 of 53;
  - dogfood/test/expression-conformance.ledger.ts: 3 of 3.
What now holds (@objectstack/spec / service-automation / lint major on the v18 line, @objectstack/formula minor; Clause-②: yes (narrowing); ADR-0087 registered flow-text-slot-single-brace-refused):
- A flow's text slots read ADR-0032 §3's {{ }} delimiter: notify title / message, screen title / description, end message.
- A single-brace {token} there is refused at the build doors and the save door, with the hole spelling as its remedy. One judge serves both doors.
- Value slots are unchanged.
Owed at landing, filed: skills(objectstack-automation): SKILL.md and eval id 2 still teach single-brace {token} in notify text slots, which PR #22315 now refuses (Tier H, owed at #22110) #22454 (Tier H, domain:skills once graded). skills/objectstack-automation/SKILL.md:108–:109 and :236–:241, and eval id 2 in evals/flows-triggers-approvals.json, still teach single-brace text slots.
Serial edges released: [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's pass 2 (service-automation builtin/template.ts) and finding(spec/automation): the value-slot refusal remedy spells list[0] for a variable named list — a CEL type name, so the remedy it tells the author to copy does not evaluate #22290 were held behind this card in the lane's serial queue. Both stay in pm:queue.
Acceptance notes carried from the reviews:
- content/docs/automation/flows.mdx's fault-edge variable table (about :1624) still shows a single-braced example with no position named;
- the stringifyForTemplate docblock (template.ts about :332–:335).
  Both are residue that the reviews recorded as not being conditions.

This act removes pm:dispatched from the closed card; the domain, area, priority, target and type labels stay.
