CLI startup banner does not surface flow-name shadowing, though it already reads the rows that carry it

The gap

collectAutomationSummary (packages/cli/src/commands/serve.ts ~5045) builds the os dev / os start startup banner by reading the automation engine's own state — including getFlowRuntimeStates() and getTriggerBindingAudit() — precisely because "a flow that failed to arm emits no log line to find" (2026-07-17 third-party eval, quoted in that function's own docblock).

PR #12026 (for #11997) makes getFlowRuntimeStates() rows carry armedFrom / shadowed for any bare flow name claimed by more than one definition, and adds getShadowedFlows() beside getTriggerBindingAudit(). The banner reads neither: its local states annotation lists the pre-existing fields only, and it prints nothing for shadowing.

So a packaged flow displaced by a same-named runtime overlay is reported in the automation plugin's logs but not in the startup summary — which is the channel that docblock says is the reliable one, since "the boot-quiet stdout window swallows plain warn/info logs".

Suggested shape

Mirror the existing unbound probe exactly — feature-detected so an older @objectstack/service-automation degrades rather than crashing the banner:

let shadowed = [];
try { shadowed = automation.getShadowedFlows?.() ?? []; } catch { /* older engine */ }

and add a banner line naming each contested flow, which definition is armed, and how many were shadowed.

Dependency

Blocked-by: #11997 — the fields and getShadowedFlows() do not exist until PR #12026 lands. Filing separately because it is in a different package (@objectstack/cli) and was out of that card's scope.

两个前提都核过了，不是回忆：

Blocked-by: #11997 已释放 — Packaged flow silently replaced by a same-named runtime flow: listItems returns both, the engine keys flows by bare name, and Map order decides the winner #11997 is CLOSED (completed) and its PR #12026 is MERGED, so armedFrom / shadowed and getShadowedFlows() exist.
文件围栏已释放 — packages/cli/src/commands/serve.ts was freed by PR #12532 (TENANCY_POSTURE_FIX_HINTS is duplicated WHOLE between serve.ts and doctor.ts — the single and group entries are byte-identical too, and only the isolated one is covered by a card #12492), merged as 1c0b9a5e3.

裁决 (⛔ not open for re-litigation)

⭐ Mirror the existing unbound probe EXACTLY — and measure what it does before copying it. The card sketches a feature-detected try { automation.getShadowedFlows?.() ?? [] } catch {}. ⛔ Do not add a tolerance shape the sibling probe does not have. If the existing unbound probe is feature-detected, match it; if it is not, ⛔ do not invent feature detection here. Consistency with the neighbouring read is the ruling; the card's snippet is a suggestion, and this seat is not endorsing its shape sight-unseen.
The banner line must name three things: which flow name is contested, which definition is armed, and how many were shadowed. ⭐ The middle one is the point — the card's whole argument is that an admin cannot tell which one is armed. A line that says "2 flows shadowed" and stops has reported the count and withheld the answer.
⛔ Do not fire on the benign case. No contested name ⇒ no line. The banner is read on every os dev / os start; a line that appears when nothing is wrong trains readers to skip it, which is how the next real one gets missed.
⚠️ states' local annotation lists the pre-existing fields only — extend it to carry armedFrom / shadowed rather than casting past it. ⛔ A cast here would reproduce, one layer up, the "declared but unread" shape the card is about.
File surface: packages/cli/src/commands/serve.ts (collectAutomationSummary, ~:5045) and its sibling tests. ⚠️ serve.ts moved twice today (PRs fix(cli): spell the multi-org runtime from its one declaration in serve's operator-facing prose #12463 and refactor(cli): single-source the tenancy posture hint table that os serve and os doctor both print (#12492) #12532) — re-read it on current origin/main; ⛔ do not trust the card's line number.
⚠️ Pin what it RENDERS. Drive a real shadowed pair through the real summary and assert the operator-visible line, not that a field was read. That is the shape fix(cli): spell the multi-org runtime from its one declaration in serve's operator-facing prose #12463 and chore(cli): pin the multi-org runtime name os doctor prints against the spec roster #12496 established on this same file.
⚠️ Prove the instrument can say no: a tree with no contested name must produce no line, and that absence must be asserted — otherwise ruling 3 is untested and the first benign boot is the test.

⚠️ #12540 is serialised behind this card on serve.ts (two const bindings above the loadOptionalServicePlugin call sites). ⛔ Do not fold it in — it additionally depends on PR #12535 landing first.

Session session_01UjujZN219uFzBhSYfMykCd · branch claude/issue-12028-banner-flow-shadowing · worktree objectstack-issue-12028 off origin/main @ c0f5e8f21.

Branch pushed empty before the first edit (write route verified).

Premise re-verified on origin/main @ c0f5e8f21, not recalled:

AutomationEngine.getShadowedFlows(): FlowShadowingRecord[] exists — packages/services/service-automation/src/engine.ts:2820.
getFlowRuntimeStates() rows carry armedFrom?: FlowContender / shadowed?: FlowContender[] — same file, :2750.
packages/cli/src/commands/serve.ts has zero reads of either. collectAutomationSummary is now at :5167 (the card's ~:5045 is stale, as ruling 5 warned).

Ruling 1 measurement (reported before copying). The sibling unbound probe IS feature-detected — serve.ts:5197:

let unbound: Array<{ flowName: string; triggerType: string; reason: string }> = [];
try { unbound = automation.getTriggerBindingAudit?.() ?? []; } catch { /* older engine */ }

Optional call + ?? [] + try/catch with the /* older engine */ comment — and the function's own docblock (:5162) states the invariant: "Every probe is feature-detected so an older @objectstack/service-automation … degrades". So the new probe matches it exactly, with no extra tolerance beyond those three elements.

File surface I am claiming (serialisation basis for parallel agents):

packages/cli/src/commands/serve.ts — collectAutomationSummary only
packages/cli/src/utils/format.ts — AutomationReadySummary + printAutomationSummary
packages/cli/src/commands/serve-automation-shadowing.test.ts (new)
.changeset/*.md (new)

⛔ Not folding in #12540 (serialised behind this card, and additionally waiting on PR #12535).

  "summary": "collectAutomationSummary now reads the ADR-0005 shadowing receipt off the engine and printAutomationSummary prints one line per contested flow name carrying all three required facts: the name, WHICH definition is armed, and how many were displaced (e.g. \"flow 'send-welcome' is claimed by 2 definitions - a runtime-authored row (sys_metadata) is ARMED, 1 shadowed (ADR-0005 overlay precedence; only the armed definition dispatches)\"). RULING 1 MEASUREMENT: the sibling `unbound` probe at serve.ts:5197 IS feature-detected (optional call + `?? []` + try/catch with the `/* older engine */` comment), and collectAutomationSummary's own docblock states that invariant for every probe in it - so the new probe mirrors exactly those three elements and adds nothing. RULING 4: the `states` local annotation now names armedFrom/shadowed; there is no cast anywhere. FORK, REPORTED NOT PICKED QUIETLY: rulings 1 and 4 describe two different data sources for the same fact (the dedicated getShadowedFlows() probe vs the armedFrom/shadowed fields on the states rows), and they are information-equivalent except in one direction - getFlowRuntimeStates() can only attach a receipt to a row it is already emitting (a name still in the flow map), while getShadowedFlows() returns every receipt the boot pull recorded. I made the dedicated probe the source (ruling 1 is starred and is the card's own shape) and extended the states annotation as a declaration rather than as a second read; a states fallback was deliberately NOT added because that is tolerance the sibling probe does not have. A second, smaller fork: @objectstack/service-automation is a workspace dep of packages/cli and exports FlowContender/FlowShadowingRecord, so `import type` was available - not used, because the probes are feature-detected precisely so an older automation package still boots the banner, and a nominal import would type the read against the current one.

No rebuild was needed or claimed for these legs: the test imports ../utils/format.js as a package-internal relative specifier, which vitest resolves to src - no dist is on the path, so the dist-preflight does not apply. Leg A, remove the render loop ('is claimed by' 1 -> 0, hash changed): 5 failed / 8 passed - exactly the five positive render pins died, the three absence pins stayed green, which is why the positive pins exist. Leg B, make the line fire unconditionally (marker 0 -> 1, hash changed): 4 failed / 9 passed - two absence pins plus the two count pins; honest note, the 'engine not enabled at all' absence pin stayed green under this mutation because that branch returns before the loop.

domain:cli seat (#6024), session session_01UjujZN219uFzBhSYfMykCd. Reviewed against origin/main and the PR ref, not against the report.

Verified independently

4 files, disjoint from every card in flight (⚠️ serve-process-child-env.e2e.test.ts asserts a SECURITY posture against the port it asked for, not the one the child bound — a lost race lets a neighbouring server answer #12548, [finding] packages/cli/vitest.config.ts's maxWorkers bullet says worker count is decided only in ci.yml — the host-level inner-pool cap from #11958 exists and the two documents cite each other one-way #12529, packages/rest has NO tsc program that compiles any test file — 149 test files unchecked, and AGENTS.md names this exact shape as how a @ts-expect-error becomes a phantom check #12542). ✔
The receipt exists where the PR says it does: packages/services/service-automation/src/engine.ts:2820 getShadowedFlows(): FlowShadowingRecord[], and armedFrom at :2750. ✔
Ruling 1 — the sibling probe was measured, not assumed. serve.ts already reads try { states = automation.getFlowRuntimeStates?.() ?? []; } catch { /* older engine */ } and the same three-element shape for getRegisteredTriggerTypes and getTriggerBindingAudit. The new probe is try { shadowing = automation.getShadowedFlows?.() ?? []; } catch { /* older engine */ } — the same shape with nothing added. ✔
Ruling 4 — zero casts. git diff | grep -E 'as any|as unknown as|@ts-expect-error|@ts-ignore' over the added lines returns nothing. ✔
Benign-case filter present — .filter((r) => r.shadowed.length > 0), kept locally where it is testable rather than inherited from the engine's guarantee. ✔

⚖️ The fork — the dev is right, and rulings 1 and 4 were mine to reconcile

The dev reported that ruling 1 and ruling 4 do not describe the same implementation, and did not quietly pick one. That is correct and it is my error, not a deviation.

I verified the asymmetry is true by construction, not just by argument: engine.ts:2767 attaches { armedFrom, shadowed } to a row it is already emitting, and a shadowed definition is not in the flow map — so getFlowRuntimeStates() emits no row for the loser. getShadowedFlows() returns every receipt the boot pull recorded. ⇒ the dedicated probe strictly dominates; the states rows are not an equivalent source, they are a subset.

⭐ Ruling: the dedicated probe is the source, as shipped. And ⛔ no states fallback — the dev's reason is the right one and is the seat's own standard: a fallback would be tolerance the sibling probe does not have. A probe that is more forgiving than its neighbours is how a family of reads stops having a single readable rule.

⭐ On the structural type over import type FlowContender: correct, and the reason generalises. The probes are feature-detected precisely so an older automation package still boots the banner; a nominal import would type the read against the CURRENT package while the runtime deliberately tolerates a previous one. A type that states a stronger guarantee than the code makes is a false green waiting for a version skew.

⭐ The declared narrowing is the right call, and I want it on the record

"the FULL packages/cli suite is NOT MEASURED here. It exceeded the container's ~10-minute foreground window and was SIGTERM-killed (exit 143) with no verdict written — recorded as unmeasured, never as a pass."

That is exactly the seat's standing reading — exit 143 means "no turn": nothing ran, and it is not a pass. Reporting it as an unmeasured narrowing with the consumer set enumerated (grep -rln for both symbols, 8 files, 63 tests) beats a silent claim of a green that never happened. ⛔ Never reconcile a killed run into a pass.

Two out-of-scope findings — both filed, and one is stronger than reported

Filed (unlabelled, per protocol): the provenance prose is written three times with nothing holding the copies equal. I checked the disagreement and it is worse than the report says — the two pre-existing copies differ on quoting and on absent-id handling:

site	spelling	absent `packageId`
`flow-precedence.ts:151`	`package "${c.packageId}"` — double	interpolates `undefined`
`plugin.ts:1139`	`package '${c.packageId}'` — single	interpolates `undefined`
`format.ts:769` (this PR)	`package '${c.packageId}'` — single	`'a code-shipped package (id unknown)'`

⭐ And the trap is exactly as the dev named it: describeFlowContender is exported and reads like the shared renderer, but it is a classifier — unknown body → FlowContender, no prose in it — so there is nothing to reuse and every caller writes its own sentence. ⛔ Not this PR's to fix; the third copy is deliberately worded to match plugin.ts, which is the best available act without a renderer to share.

Also filed: the check:i18n / check:i18n-coverage serial-discovery tax — four locked rounds spent to get one reading, because each run names only the first missing module.

One note on your own disproof, kept because you were right to record it

describeFlowContender's String(packageId) cannot render package 'undefined' — isCodeArtifactBody (packages/objectql/src/registry.ts:1137) returns false on a falsy _packageId. ⭐ Recording a checked-and-disproven hypothesis so the next reader does not re-derive it as a live bug is worth as much as a finding, and it is why the CLI helper's defensive branch should not be read as evidence of one.

Un-drafted. Enqueueing on every check green — not the required subset. ⚠️ Its merge releases packages/cli/src/commands/serve.ts, which frees #12543, #12533 and #12540 together.
