Production regression of T1 (7829acc..15e3863). User reports "明明生成
了很多文件,但只有一个" — the filesystem shows 19 markdown deliverables
in ~/Documents/Github/test/{business-plan,operations,ceo-coordination}/
but the DocumentCenter surfaces only one row.
Root cause is structural, predicted in spirit by Karpathy's Round 1
take ("把'认知'和'执行'两件事一起锁是数据结构错"). The T1 rewrite
collapsed two concerns into one nullable field on the run context:
workspacePath = workspace?.localPath ?? null
^^^^^^^^^ ^^^^
lock target observation root
For lockMode='none' (every cognitive C-suite agent post-T1) the
resolver returns workspace=null, so workspacePath was null, so
artifact-projector.ts:242 short-circuited every projection with
`{ kind: "skipped", reason: "no_workspace" }`. The agents kept
writing files via bash (cwd falls back to the company default
workspace at worker/runtime/index.ts:142), but nothing observed
them — the DocumentCenter only saw the one file that was projected
back when the agent still held an exclusive workspace.
Fix: split the two concerns. WorkspaceResolution gains a non-lock
`observationPath` field; the resolver populates it from the company
primary workspace (new `getCompanyObservationWorkspace` query —
primary first, oldest second, null only when company has zero
workspace rows) for lockMode='none' runs, and from `workspace.localPath`
itself for lockMode='exclusive' runs. RunDispatchParams threads the
field through; turn-context's `workspacePath` reads it first.
artifact-projector.ts is unchanged — it just sees a non-null path
again and resumes baselining, diffing, and upserting work_products
rows the way it did pre-T1.
Three new unit tests pin the regression: cognitive role with
workspace ⇒ observationPath set; cognitive role with no workspace ⇒
observationPath null; exclusive ⇒ observationPath equals
workspace.localPath. typecheck green, 543/543 unit tests, 10/10
eval. No fallback, no mock, no silent degradation.
Old resolver: task → agent → project → any company workspace, all
marked exclusive. That fourth step folded every runnable agent in a
multi-agent company onto a single workspace row and serialised the
C-suite (four agents, one exclusive lock, three starved).
New resolver: lockMode='exclusive' is now an opt-in decision inferred
per task. Three rules:
1. task.workspaceId set → exclusive on that workspace (explicit).
2. filesystem signal (task.requiresFilesystem OR agent in a
coding role/engineering department) → exclusive on
agent.workspaceId / project primary; throws if neither exists.
3. otherwise → none / null. Pure cognitive work runs with no
workspace lock and fully in parallel.
Removed:
- company_fallback silent-share path. Filesystem-touching runs
with no legitimate binding now throw WorkspaceConfigurationError
at resolve time so the caller decides recovery rather than the
resolver picking a random shared workspace.
- workspacesMod.getAnyCompanyWorkspace (now dead code).
Invariants now enforced by types:
- lockMode='exclusive' ⇒ workspace is a live WorkspaceRecord.
- lockMode='none' ⇒ workspace is null.
Tests updated to cover the new decision table and the four-non-
coding-agents parallel case that was the original bug.
Closes the second and final ask from the C4 cross-review (Karpathy
specific ask #1). The previous non-ceo-dm-reply recording (409bec2)
pre-dated C4 part 3/5 by ~18 minutes, so it could not discriminate
between "non-CEO path correctly does not receive hire_agent /
file_approval" and "the tools simply had not been injected yet."
Re-recorded against anthropic/claude-sonnet-4-5 on the current main.
The VP Product agent (manager — canRequestHire=true by keyword match,
but after F3 canFileCeoStrategy=false because reportsTo is not null
AND role is not CEO) produces:
- mark_read + /api/agent_message/send + m_77 preserved — 3 positive
assertions intact.
- Zero hire_agent invocation (not asked to hire).
- Zero file_approval invocation — positive evidence the F3 split
correctly excludes file_approval from non-CEO managers. Without
F3 this call would have had file_approval in scope and a manager
under pressure might have reached for it.
Fixture assertions updated to pin the two tool-scope invariants using
the new message_does_not_contain_substring kind from F2.
C4-followup.md marked CLOSED with resolution table mapping each of
the four items to its landing commit, plus the companion cleanup
(43337e5 — RpcMethod single-source-of-truth) that came out of the
same session.
Final: typecheck green, 537 unit tests, 10 eval tests.
