Why: Integrate the exact Dev main pin while preserving trusted project context, vision routing, work-result context, and distinct migration identities.
Evidence: go vet ./...; go test ./... -count=1; go build ./...; CGO_ENABLED=0 go build ./cmd/agent-system; isolated PostgreSQL migration history tests.
Impact: Keep exec_env_layers at schema v35, move the feature migrations to v36-v46 in order, and fail closed on the old unpublished numbering.
Refs: 14e780c6fa32fdd4742b6232150c5efcb0d766ff; ab12fea474
Why: Background notice runs blocked chat, truncated results, and duplicated deliverable execution.
Evidence: Focused run manager, card, server, recovery and race regressions pass locally; final combination checks are tracked in Dev.
Impact: Persist full results and optional choices, fence dispatch by run identity, retain public child process, and repair legacy projections without a schema change. No paid model trial was run.
Refs: feature/workbench-flow-completion
Why: Project work currently reaches model calls without current authorized project facts or a persisted input receipt.
Evidence: SELF go test ./... -count=1, targeted go test -race for W6 paths, go vet ./..., and CGO_ENABLED=0 go build ./cmd/agent-system passed on this change set.
Impact: Add optional X1 interfaces, trusted persisted work-task binding, request-scoped context injection, evidence reauthorization, and attempted/responded/unknown manifests. Existing non-project behavior stays available.

Why: the dual-speed entry hint is advisory only; real runs (MiniMax, 3 attachments, no text) end with a clarifying question and zero delegation, so background cards and result backfill never start.
Evidence: new unit tests in runmgr/material_test.go and runtime/material_flow_test.go all pass; full go test ./... exit 0 (local, SELF).
Impact: attachment-carrying runs now guarantee a material-organization background task (pre-spawn on attachment-only/heavy sends, stop-hook backstop otherwise when the model did not delegate); subagent receives inline parsed text with budget plus knowledge_search guidance; content-key dedup prevents duplicate spawns (in-flight, completed, resend); model-authored delegate_task gains a materials appendix; settings runtime.materialIntake (default on) and runtime.materialIntakeChars added.
Refs: Dev task .task/feature-material-intake-flow.md I1; user ruling 2026-10-11.
Why: Real runs were fully serial: the direct path never set the kernel's
parallel tool mode, delegate_task handed the parent only the child's
160-char summary (the full text was dropped), MiniMax streamed its
reasoning inside content <think> blocks, and the EXT-16 sandbox hid
~/.local so python-docx/openpyxl/pptx could not even import. All four
were measured defects (F1/F2/F3/F5) in the delegation/routing proposal.
Why: Serial-only mutual exclusion is not enough for order-sensitive
tools - the card-stream test failed with out-of-order appends - so the
ordering moved into the kernel (SerialTools partition, Agent-Native
#44); process events pair by CallID (#42) and tool results write back
through the injected call context (#43).
Evidence: go test ./... green, including new regression anchors:
TestDelegateToolReturnsFullText, TestToolEventsPairByCallID,
TestToolExecModeAndSerialSet, TestOpenLLMClientReasoningSplitAuto,
TestSandboxArgvDepsLayer, TestExecEnvJoinsPythonPath.
Impact: Direct runs now execute independent same-turn calls
(searches, reads, delegate_task, review_findings) concurrently by
default (runtime.parallelTools=false restores sequential); card flow,
plans, workflows, exec primitives and file edits keep model-declared
order. delegate_task returns the capped full child text. MiniMax-*
models get reasoning_split=true so thinking streams via
reasoning_content. --exec-deps-dir/AGENT_SYSTEM_EXEC_DEPS_DIR mounts a
read-only dependency layer into the sandbox and merges PYTHONPATH.
Bumps deps/agent-native to c348441.

F1-F5); Agent-Native #42/#43/#44; Dev task feature/agent-e1-parallel-fixes.
Why: subagent runs recorded zero tokens, cache hits were invisible in
run records, the usage event skipped terminal paths, and stream retry
existed only on the direct-chat path (audit N20 residual).
Evidence: go test -count=1 ./... green; TestRetryAttemptsMapping
(setting 0=off→-1, N→N), TestDirectRunUsageSplitOnRecord (Last* and
cache land in the run usage), TestSubRunAccountsTokens (subagent
accounting), TestAddUsageAccumulatesSplitFields (handle chain); pins
carry Agent-Native#35/#37/#38/#39, Agent-Squad#41, Core Usage fields.
Impact: run.Usage carries Last*/cache on every path; subagent runs are
accounted; runtime.llmRetries maps onto the library default (setting 0
disables via -1); the verifier wraps retry+fallback explicitly; retry
events surface as process parts.
Refs: Agent-Native#35-#39, Agent-Squad#41, N3 plan WP6
Why: spans now follow the OTel GenAI convention (Agent-Native#32); the
product needs the settings surface for the exporter, a meaningful
service.name, and per-profile agent names.
Evidence: go test -count=1 ./... green; TestTelemetryFlagsDefaults
(otlpEndpoint registered default empty = no export, serviceName
default agent-system-backend); nested pins carry the convention work.
Impact: nothing is exported unless telemetry.otlpEndpoint (or the env
var) is set; agent spans are named by profile id.
Refs: Agent-Native#32, Agent-Squad#36, N3 plan WP4
Why: N1 increment three host side - plugin agent assets must reject
hooks/mcp/permissionMode declarations (WP1 acceptance), and squad
members need the kernel ask port wired to the HITL card (WP4).
Evidence: go vet clean; go test ./... 29 packages ok, including new
agent-asset tests (banned keys located to the field, unknown keys,
missing id) and the V2 asset suite. Nested pins at native c5b9dca
(PR #18) and squad fc9620e (PR #17).
Impact: plugins agents/ assets now parse via parseAgentAsset
(strict JSON with banned-key rejection); PermissionAskOf exported
and takes any host with the optional method; app.go wires
cfg.PermissionAsk for the squad path. Legacy behavior unchanged when
nothing registers the port.
Refs: Documents proposal 2026-10-07-agent-stack-n1q1i1-plans.md WP1/WP4
Why: N1 WP2/WP3 host side - the kernel ask loop must reach the HITL
confirm card, and tool gating should run through the typed Policy with
the session-allow store port instead of a hand-built Request.
Evidence: go vet clean; go test ./... all packages ok, including new
TestConvAllowStoreKeysByName, TestPermissionAskRoutesToHITL, and
permissionAskOf tests. Nested agent-native pin at 9758a8d (PR #17).
Impact: runmgr.ExecuteTool decides via agentpolicy.Policy with
convAllowStore (keying unchanged: conversation x tool name);
runCtx.PermissionAsk routes kernel asks to the shared toolConfirmCard
HITL; direct and subagent loops pass PermissionAsk into the kernel
config (nil for hosts without the method, preserving legacy ask=reject).
Refs: Documents proposal 2026-10-07-agent-stack-n1q1i1-plans.md WP2/WP3; Agent-Native PR #17
Why: workspace writes had no checkpoint, and a 5xx before any output stopped the turn instead of trying the next configured model.
Evidence: GOWORK=off go test ./internal/runtime/ ./internal/runmgr/ ./internal/tools/ ./internal/settings/ ./internal/server/ ./internal/app/
Impact: models.chat.fallbacks defaults to empty, so existing runs keep their model. Rewind restores only tracked writes and appends a system note. Usage records the model that served.

Why: Byte truncation split UTF-8, subagent results could return unbounded text, and a write could overwrite a file that changed after it was read.
Evidence: cutRunes keeps a two-character Chinese prefix; tool selection honors -name; checklist reminders go through the reminder bus.
Impact: Tool output limits count characters. A subagent result over 32000 characters is stored as an artifact and the parent sees the path. fs_write_file rejects an existing file that was not read in this run.
Refs: feature/context-engineering
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: Tool calls stayed invisible until execution finished, and turn, tool, timeout, and output caps stopped long tasks early.
Evidence: go test ./internal/runtime/ ./internal/tools/ ./internal/prompts/ ./internal/squadadapter/ ./internal/runmgr/ ./internal/app/ ./internal/settings/
Impact: tool.call.delta and tool.output reach the client; default profile, subagents, and squad no longer cap turns or tool calls; exec timeout defaults to 600s with no hard ceiling. A profile or subagent maxTurns above 0 still applies.
Refs: feature/stream-display-overhaul
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: A parent turn should be able to finish while children keep working, and a review should keep only findings that a second pass confirms. Users also need to override a profile's tools, model, and turn cap without adding dispatch tools.
Evidence: go test ./... passed. New cases cover overlay rejection, role mapping, queued notices, and dropping FAIL or unparsed findings.
Impact: Notices live only in memory, and each conversation allows three background children. Squad writer steps now use the writer profile.
Refs: feature/agent-harness-p3b
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: Subagents were a single lightweight call that dropped the hint and wrote their messages into the parent history. Profiles now decide tools, model, and turn cap, and the parent only keeps the summary plus confirmed artifacts.
Evidence: go test ./... passed. New tests cover the six builtin specs, tool execution and whitelist, explore versus writer models, maxTurns, artifact parts, hint text, SpawnAgent pinning, depth-1 refusal, summary artifact lines, and history isolation.
Impact: Squad steps share the general profile (up to 12 lightweight turns, no exec tools). Child runs do not attach the final-turn verifier. Profile fields stay in builtin files, so core.PromptModule is unchanged. The agent-native pin stays a34689c.
