Why: native d6053baf (Agent-Native#26, N2 WP2) and squad 41ea2766
(Agent-Squad#30) carry the native Anthropic client; the nested pins
follow for the Dev combination check.
Evidence: go build + go test -count=1 ./... green on this combination.
Impact: none beyond the pins.
Refs: Agent-Native#26, Agent-Squad#30
Why: trimOldest dropped single messages without tool-pair awareness —
after leading users were evicted it could orphan tool results or leave
dangling calls (acceptance clause 2's product-side gap).
Evidence: go test -count=1 ./... green; TestTrimOldestKeepsToolPairs
(pairing holds across repeated trims), TestTrimOldestDropsLeadingOrphanToolRun,
TestTrimOldestStopsWhenGroupCrossesCurrentTurn, TestPrefixHashStableForIdenticalInput;
native pins carry the spill and cache-contract work (Agent-Native#25).
Impact: trimming now evicts whole tool groups; the window may be
slightly exceeded when a group would cross the current turn — pairing
is never broken. Report.Truncations still records the count.
Refs: Agent-Native#25, Agent-Squad#29, N2 plan WP1
Why: native ead690be keeps workspace-less requests out of the process
CWD (the Dev CI build step requires a clean tree after make test);
squad 029edc08 carries it.
Evidence: go build + go test ./... green on this combination.
Impact: none beyond the pins.
Refs: Agent-Native#24, Agent-Squad#28, Agent-System-Dev#242
Why: squad main (551e11ec) and native main (3a1ad5a) now carry the
nested agent-intent 343b1e6 pins the Dev combination check requires;
the backend nested copies follow.
Evidence: go build ./... green on this combination; trees identical
to the merged library mains.
Impact: none beyond the pins.
Refs: Agent-Squad#27, Agent-Native#23, I2 increment 3 cascade
Why: the slow-lane wiring references SemanticScorer/CommandGenerator,
which only exist on agent-intent main after #9/#10; the pin must move
for CI to build the new packages.
Evidence: deps/agent-intent now at 343b1e6 (merged main).
Impact: none by itself.
Refs: Agent-System-Backend#83, I2 increment 3
Why: I2 increments 1-2 shipped the agent-intent ports (SemanticScorer,
CommandGenerator); the backend still had no implementation, so the slow
lane could not be enabled in the product.
Evidence: go test ./... green; lint-boundaries ok; the two new
runtime.intentSemantic / runtime.intentGenerator flags are registered
with default false and the gate defaults to the I1 recognizer when both
are off (TestIntentSlowLaneFlagsDefaultOff, TestGate*).
Impact: no behavior change by default; enabling runtime.intentSemantic
routes ambiguous rule matches through embedding cosine scoring, and
runtime.intentGenerator lets the lightweight model propose commands on
fallback with library-side fail-closed validation. Nested agent-intent
pin moves to 343b1e6 (I2 increments 1-2).
Refs: I2 increment 3
Why: Agent-Squad PR #26 landed the SQLite Store, single-DB mounting
and the Executor-port fix; backend must carry the same head or Dev
check-pins fails.
Evidence: backend suite 30 packages ok at this combination.
Impact: Nested squad pin only.
Why: Agent-Squad PR #25 landed the Store port, tiered checkpoints
and the termination registry; backend must carry the same head or
Dev check-pins fails.
Evidence: backend suite 30 packages ok at this combination.
Impact: Nested squad pin only.
Why: Agent-Squad PR #24 landed attempt ids and product-checked
interrupted recovery; backend must carry the same head or Dev
check-pins fails.
Evidence: backend suite 30 packages ok at this combination.
Impact: Nested squad pin only.
Why: Agent-Squad PR #23 landed the superstep engine; backend must
carry the same squad head or Dev check-pins fails.
Evidence: backend suite 30 packages ok at this combination.
Impact: Nested squad pin only.
Why: Squad PR #22 landed the nested native bump; backend must
carry the same squad head or Dev check-pins fails.
Evidence: squad main head is the #22 merge.
Impact: Nested squad pin only.
Why: Agent-Intent PR #8 and its cascades (Squad #21, Native #22)
landed; backend's nested pins must carry those heads or Dev
check-pins fails.
Evidence: backend suite 30 packages ok at this combination.
Impact: Three nested gitlinks.
Why: The boundary linter allows agent-intent imports only in the
adapter layer; route and runmgr consume aliases from intentgate
instead of importing the ecosystem library directly.
Evidence: lint-boundaries passes below; backend suite green.
Impact: intentgate re-exports Command/ActionRef and the kind
constants; route drops the agent-intent import.
Why: Squad PR #20 and Agent-Native PR #21 completed the intent
cascade; backend's nested pins must carry those heads or Dev
check-pins fails.
Evidence: squad and native heads are direct merges on their mains;
backend suite green before the pin bump.
Impact: Two nested gitlinks.
Why: I1 WP3 - chat routing and the HITL free-text pivot now share one
router consuming the library's command list, and both intent hosts
fold compatibility-equivalent input.
Evidence: go vet clean; go test ./... 30 packages ok, including the
existing workflow-route and server e2e suites unchanged (behavior
parity) and the new route package tests.
Impact: new internal/route package (unique router with explicit
priority rules); intentgate carries Commands and folds NFKC;
server.go and runmgr.go route through it; nested pins at intent
2554b50 and squad 6b7a991. Blueprint actions resolve to a squad
decision at the router level; per-run squad entry stays a recorded
follow-up (no silent misrouting).
Refs: Documents proposal 2026-10-07-agent-stack-n1q1i1-plans.md I1 WP3/WP4
Why: Agent-Squad PR #18 landed the nested agent-native WP5 bump;
backend must carry the same squad head or Dev check-pins fails.
Evidence: squad main head is the #18 merge; backend suite runs next.
Impact: Nested squad pin only.
Why: N1 WP5 host side - directRun.stop and the checklist reminders
now call the library gates package behind product ports, and the
nested native pin moves to the merged WP5 head.
Evidence: go vet clean; go test ./... 29 packages ok, including the
characterization suite unmodified and the new wp5_ab_test.go
(verify-cap continuation counts and gate-reason text parity).
Impact: llm.go drops the local regex family and deliverableGate;
verify.go drops checkDeliverables/parseVerdict/stripFence and the
local caps; workflow.go switches to gates.Verdict; reminders run
through gates.ProgressReminder. Behavior is pinned identical by the
existing suite plus the A/B tests. Squad reminders stay out of this
increment (adapter lacks per-member tool-turn signals - recorded as
WP6b).
Refs: Documents proposal 2026-10-07-agent-stack-n1q1i1-plans.md WP5/WP6
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: Agent-Squad PR #16 landed the nested agent-native bump; backend
must carry the same squad head or Dev check-pins fails.
Evidence: squad main head is the #16 merge; backend test suite runs
next.
Impact: Nested squad pin only.
Why: Library PR #17 landed on agent-native main as c2befaf; backend
compiles with the merged combination, not the pre-merge branch head.
Evidence: go vet and full go test run next; native main ancestry of
9758a8d verified before the pin bump.
Impact: Nested agent-native pin only.
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: review of EXT-5 found a column-cap cell (common styled XFD cells) wrongly reported the 200k-cell cap and aborted every remaining worksheet; malformed sheet XML was also dropped silently, contradicting the explicit-failure contract; the legacy-office parser id was missing from the registry.
Evidence: local GOWORK=off go test ./... 29 packages pass with new regressions (wide column keeps later sheets, bad sheet XML warns, registry maps doc/xls/ppt); go vet clean; recorded as SELF on the Dev task card.
Impact: xlsxSheetBlocks returns wide/badXML signals; wide cells skip with a per-sheet warning, cell-cap truncation unchanged; builtin:legacy-office added to ParsersDescription.
Refs: review of backend 727f370; documents proposal 2026-10-06-ext-5-host-parse-document sect.2.
Why: downstream parsers are unreachable via extension.Host and the base lacked xlsx/pptx parsers; MS1 needs Excel and PPT ingest (EXT-5 request, documents proposal 2026-10-06-ext-5-host-parse-document).
Evidence: local GOWORK=off go test ./... all 29 packages pass incl. new ooxml_test (hand-built parts), ooxml_python_test (openpyxl/python-pptx round-trip), inproc owner-scope and limit tests, xlsx upload e2e; go vet clean; recorded as SELF on the Dev task card, PR CI to confirm.
Impact: Host gains ParseDocument (pure compute; errors only on ctx cancel or >100MiB input); builtin:xlsx (sheet order via workbook.xml rels, rich-text shared strings, formula cache, 1900/1904 dates, sparse cells) and builtin:pptx (sldIdLst order, titles, group shapes, AlternateContent Choice, tables, notes) added with 200k-cell/64MiB-part caps; legacy doc/xls/ppt get an actionable hint; ParsersDescription gains xlsx/pptx and the missing text ext; surface snapshot now records exported interface methods; docx part reads share the 64MiB cap.
Refs: documents 2026-10-06-ext-5-host-parse-document.md; EXT-1 host.go precedent.
