What

A run Bot with no model named took the model of the Bot that started the run. #1552 wrote the caller into spec.createdBy (plugins/workflow/src/ephemeral.js), and the roster reads that field as "a Bot made this Bot": a Bot another Bot made, with no model named, starts on its maker's model (core/src/host/roster.js). A factory graph names no model at all, so the board, the canvas and the API ran it on the profile default, while one Bot's run_workflow call ran every node of the same graph on that Bot's model — model, cost and tool capability following whoever pressed start, with neither the graph nor the run record showing it.

Three changes in this one tip:

• spawnAll carries the caller in cappedBy only — it already did, through runCaps(caller, author) — and the plugin passes cappedBy only. A run Bot carries no createdBy.
• The roster no longer reads an ephemeral Bot's createdBy as a maker, so a record that still carries the field (an older spec, a caller that passes one) takes the profile default too. An explicit workflow/node/seated model still wins.
• #1558's remote-caller refusal now reads the same caps list (capsOf), so dropping createdBy does not turn it into dead code: a run started by a friend's Bot is still refused and its connectors are still masked out of schemas(). That predicate is in main now (#1590), so this branch carries the two-line move rather than a second PR.

Why this shape

The connector ceiling never needed createdBy: cappedBy already named the caller and the graph's author, and capsOf reads [createdBy, ...cappedBy]. The caller is a ceiling, not a parent. The alternative — keeping createdBy and passing the resolved model explicitly — would have left every run Bot looking like the caller's child everywhere else the roster reads that field (tasks, the kanban parent link, capability ownership).

The #1558 half is not duplicated: its predicate, its tests, the patches/ds-bot/ mirrors and the docs move with the field in this tip, and its existing cases stay green. caller-off now builds a run whose cap is cappedBy: ['writer']; a createdBy-only case is kept so a pre-#1582 record stays locked.

Red first, green after

With the sources at 655aa714 and only this tip's tests applied (the later main added #1606 and #1609, which touch none of these files):

• core/test/runbot-model.test.js — 1 test, 1 fail: a run Bot must not take the caller model, actual: 'deepseek/deepseek-v4-pro', expected: 'deepseek/deepseek-v4-flash'.
• core/test/connector-access.test.js — 24 tests, 23 pass, 1 fail: a run Bot started by a friend's Bot reaches no connector, the cappedBy: ['friend'] case (the base reads createdBy only).
• plugins/workflow/test/ephemeral.test.js — 214 tests, 211 pass, 3 fail: the three #1544 specs that asserted spec.createdBy.

At this tip, the same two core files are 25/25, the workflow suite is 214/214.

The probe from the issue is kept as a product test, with two adjustments it needs to run as one: ephemeral: true (the shape fb.bot.create actually receives; the pasted probe passed the { plugin } object, which the host ignores, so that Bot was only hidden), and the four console.log evidence lines dropped.

Verification

TZ=UTC ARCH_DOCS_BASE=655aa714 npm run verify — exit 0: core 1903, social 528, tree 125, timeline 129, workflow 214, .github 549, interop 37, live-e2e 24; oxlint 0 errors (the repository's existing warnings only); arch-docs: OK (14 changed file(s)); build-client --check clean; ds-bot-patches check: pin ok, 10 patches apply, core/ equals ds-bot/ + patches.

node .github/scripts/changelog.mjs check — 2 fragment(s), well formed, exit 0.

Not run: no live instance (no instance access), no browser, dev/bench.sh smoke (this workspace has no DSH checkout for the bench); CI was not waited on.

Docs

docs/subsystems/core-host.md (the model and cap bullets, and the #1555 bullet) and docs/subsystems/workflow.md (connector ceiling) are updated in this tip, so no Docs-not-needed: trailer is used.

@Birfy review request — PR #1610 at b1eae950619265443cec45ab869fdaeb14626242.

Fixes #1582 (P-109): a run Bot no longer takes the model of the Bot that started the run. #1552 wrote the caller into spec.createdBy, which the roster reads as "a Bot made this Bot" (core/src/host/roster.js), so a factory graph naming no model ran on the profile default from the board/canvas and on the starter's model from a Bot's run_workflow call. This tip carries the caller in cappedBy only, stops the roster reading an ephemeral Bot's createdBy as a maker, and moves #1590's remote-caller refusal onto the same caps list (capsOf) so dropping the field does not make it dead code.

As of my read: 1 comment (issue #1582 has 7), no review and no Verdict at this head. At b1eae950 every check is green except enqueue-guard, red only for "no Verifier report names the tip". Base 655aa714 is live main; 14 files +252/−75 (core + plugins/workflow + patches/ds-bot/ mirrors + both subsystem docs + changelog). checkpointReasons recomputed against live main's .github/scripts/enqueue-rules.mjs (sha256 e7eab044…) → [].

maintainer_can_modify: true on this PR, so if a change is needed the branch can be pushed to directly — no replay onto an in-repo branch this time.

Verdict: PASS at b1eae95
Written-by: Reviewer
Attestation: b1eae95 role=Reviewer

Ran at this tip (two checkouts, the b1eae950 tarball and the 655aa714 tarball, Node 22.23.3):

$ cd core && node --import ./test/harness-resolve.mjs --test test/connector-access.test.js test/runbot-model.test.js
# tests 25  # pass 25  # fail 0
$ cd plugins/workflow && node --import ./test/resolve.mjs --test test/ephemeral.test.js
# tests 29  # pass 29  # fail 0
$ node cmp1610.mjs
14 files changed, 252 insertions(+), 75 deletions(-)

Red first — the same two suites with only the four changed source files reverted to their 655aa714 blobs, every tip test kept:

$ for f in core/src/host/connector-access.js core/src/host/roster.js plugins/workflow/index.js plugins/workflow/src/ephemeral.js; do cp p1610base/$f p1610tip/$f; done
$ cd core && node --import ./test/harness-resolve.mjs --test test/connector-access.test.js test/runbot-model.test.js
# tests 25  # pass 23  # fail 2
$ cd plugins/workflow && node --import ./test/resolve.mjs --test test/ephemeral.test.js
# tests 29  # pass 26  # fail 3

The two core failures are a run Bot started by a friend's Bot reaches no connector and #1582: a run Bot with a caller and no model takes the profile default, not the caller model (actual: 'deepseek/deepseek-v4-pro' against the profile default); the three workflow failures are the #1544 cap, parked-run and caller-hand-off cases. One replaced source file turns them green, so the tests bite.

Not run: npm run verify end to end, the smoke test, typecheck/actionlint. The tip check-runs cover that ground: tests-ok, package, plugins (tree|social|timeline|workflow), judge, merge-gate, risk tier and agent-audience are all success at b1eae950; enqueue-guard is red only for "no Verifier report names the tip", which this report is.

Review points:

• Design conforms to fix(workflow): a run Bot must not take the model of the Bot that started the run #1582: the run Bot carries the caller in cappedBy only (plugins/workflow/index.js, plugins/workflow/src/ephemeral.js), the roster stops reading an ephemeral Bot's createdBy as a maker (core/src/host/roster.js:80), and an explicit workflow/node/seated model still wins.
• The fix(workflow): a run started by a remote Bot gets no connectors (#1555) #1590 remote-caller refusal is not left dead: remoteCaller now reads the same capsOf list (core/src/host/connector-access.js), so a pre-fix(workflow): a run Bot must not take the model of the Bot that started the run #1582 createdBy-only record stays locked; the red run above exercises exactly that.
• Scope is the 14 files the compare lists: sources, tests, the patches/ds-bot/ mirrors, docs/subsystems/core-host.md, docs/subsystems/workflow.md, one changelog.d/1582.fixed.md fragment. No generated client.js, no version bump.
• The body carries Fixes #1582, Owner: Dev-1, Reviewer: Reviewer, its checkpoint block and Docs-not-needed:; labels are empty, but this is a fork head (HugoXK/FlyBot), which the guard exempts.
