Why: Q3 WP4 requires A2A 1.0 interop from zero: publish this team's
capabilities as an Agent Card and consume remote agents as squad.Executors
with the A2A task state machine mapped onto ExecResult.
Evidence: adapters/a2a conformance with a local fake A2A server (both
directions): card build from role/blueprint registries, well-known JSON
serving, FetchCard fail-closed validation, message/send -> tasks/get
polling through submitted/working -> completed with TextPart/FilePart
artifacts mapped to patches/targets, failed/canceled/rejected/input-required
mapped to Success=false fail-closed (no cross-process hold), direct Message
result, JSON-RPC protocol and ctx-cancel error propagation. Module green
with -race; squad root suite unaffected (SELF). CI authoritative (GATE)
for the root module; the adapter module follows the adapters/intent and
adapters/native separate-go.mod precedent.
Impact: new module agent-squad/adapters/a2a (card.go, executor.go); no
changes to the squad root module.

Why: the exec bridge now threads Last*/cache (Agent-Native#39); squad
ProcessEvent carries them to hosts (the product's squad runner reads
them for usage accounting).
Evidence: GOWORK=off go vet green across squad and adapters/native;
nested pin at the merged native.
Impact: additive event fields.

Why: Q1 WP5 - platform's SQLite becomes an implementation of the
squad Store port so run state and orchestration state live in one
database, and platform's in-process execution goes through the
Executor port instead of bypassing it (X6).
Evidence: all five modules go vet clean and go test ok, including
engine-on-SQLite (state in DB, no run-level JSON files, second
engine recovers from the same DB), SQLiteStore round trip, and the
full squad compatibility net.
Impact: runState/hitlGate exported so the port is implementable;
Options.Store wires into engineDeps; leader persistence and
checkpoints route through the port; PrepareWorkspace no longer
writes run-level JSON (st.save owns it); platform RunInProcess
takes squad.Executor (callers updated); serve mounts the engine on
platform's RunStore - single orchestration.db for both.

Why: Both intent hosts should fold compatibility-equivalent input
(backend intentgate already does); the nested pin carries the I1
command model the gate depends on.
Evidence: adapters/intent suite ok; all five squad modules green.
Impact: NFKC on in NewFromOverlay; nested agent-intent at 2554b50.
Why: Squad members must reach the host's HITL verdict when a kernel
hook answers ask - the new native GateOptions.PermissionAsk field
carries it; nil preserves the legacy ask=reject behavior.
Evidence: go vet clean in all five modules; go test ok everywhere.
Impact: Additive Config field plus its buildOptions mapping.
Why: squad members use the same native kernel, so the script switch and the user-input callback have to reach that backend.
Evidence: GOWORK=off go test . in adapters/native.
Impact: the new fields default to off and nil, so existing member runs stay the same. The agent-native pin moves to the orchestration commit.

Why: squad members write files and call tools through the same kernel, so rewind and span hooks have to reach that backend.
Evidence: GOWORK=off go test . in adapters/native.
Impact: nil checkpoints and a nil trace func leave member runs unchanged. The agent-native pin moves to the durability commit.

Why: Squad members used the same kernel as direct chat but dropped stop, reminder, and before-tool hooks.
Evidence: GOWORK=off go test . in adapters/native passed after pinning agent-native to 99d623a.
Impact: Zero GateOptions still builds the previous backend. A set BeforeTool now runs inside the member loop.

Why: the command has to load guard overlays without naming agent-intent types. Only adapters/intent may import that library.
Evidence: GOWORK=off go test -count=1 in adapters/intent and cmd/agent-squad passed.
Impact: CLI calls NewFromOverlay. Guard domains stay guard.

Why: the squad core has to compile without agent-native or agent-intent. Ports stay in the core; adapters and the CLI own the concrete clients.
Evidence: GOWORK=off go test -count=1 ./squad/ ./store/ ./textextract/ ./schema/ passed, and the intent, sqlite, native, and cmd modules passed their own go test.
Impact: core go.mod keeps error-code-system only. Nested gitlinks stay. Callers register the native backend through agent-squad/adapters/native.
