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.

Why: Downstream products must extend the base through a public package and host API instead of editing internal code.
Evidence: go test ./... passed, including plugin v2 assets, sidecar startup, migration v13, pending confirms, HITL timeout, hash embedder, command pairs, and the extension surface snapshot.
Impact: apiVersion 2.0-experimental rejects empty network allowlists for declarative HTTP. Hash embeddings stay opt-in via models.embedding.provider=hash. Plugin secrets resolve per owner at execution time.

Why: D48-D51 approved — cross-session inbox so todos are not lost across
conversations.
Evidence: store v12 index + ListProjectCards aggregate (D49 verdict:
project cards any status + per-conversation action_required only);
cardsvc project-stream emit/mirror via project:<id> pseudo-key (helpers
in core PR #11/#12) and ToProject (idempotent via ref, dismisses origin,
refuses flow-bound hitl/cmd cards); runmgr scope=project ownership;
llm.go scope param on submit_card/card_begin; server routes
GET /api/projects/{id}/cards, POST /api/cards/{id}/to_project, events
scope=project; vendored core synced; new tests ToProject/,
TestLLMRunnerCardScopeProject, e2e TestProjectInbox; e2e server now
wires production card emitter (no-op before).
Impact: additive; no change to existing conversation flows.
Refs: documents proposal 2026-09-30-card-stream-artifact-unify-project-inbox.md (D48-D52).
Why: conversation transcripts were the only project channel not
readable across sessions (artifacts/knowledge are already shared),
which caused duplicate parallel work; see proposal
2026-09-30-cross-session-reading.
Evidence: runmgr/crossread_test.go covers the full gate matrix
(project gate on/off x outbound flag x private target x cross-project
x cross-tenant x self-read x archived x limit clamping) against a real
store + settings chain; store tests cover migration v11, flag
persistence and tenant isolation; tools/peers_test.go covers args
validation, transcript rendering and the untrusted-content banner;
go test ./... green.
Impact: setting crossSession.read (default off, schema-driven);
conversation columns allow_cross_read (default true) and cross_private
(default false) with PATCH support; builtin tools list_conversations
and read_conversation gated fail-closed in runmgr toolCtx; nested
agent-system-core pin bumped to fd44179 (Core PR #6).

(Dev task feature/cross-session-reading).
Why: the user ruled out self-registration (2026-09-30): accounts are
created only by admins who set an initial password; first login (and
first login after any admin reset) must force a password change.
Evidence:
- migration v10 auth_accounts (users password/must_change/is_admin +
sessions table; upgrade test walks v1<->v10 both directions).
- argon2id hash/verify with PHC encoding; store tests cover hash
roundtrip, duplicate-owner conflict, must-change lifecycle, session
keep/except semantics.
- e2e TestAdminAccountFlow: static login page reachable without auth,
wrong password 401, login sets HttpOnly cookie + mustChangePassword,
admin creates user (409 on duplicate), non-admin create 403, forced
change clears flag and old password dies, admin reset revokes sessions
and re-arms forced change, API-key channel untouched, 5-fail backoff
429, logout kills session. Full go test ./... green.
Impact: middleware now accepts Bearer key OR session cookie and exempts
static + /api/auth/login (also fixes the latent case where the login
page itself could 401). Embedded no-auth mode unchanged.
Refs: proposal 2026-09-30-ui-redesign-and-auth.md section 5 (admin-issued
variant, user decision 2026-09-30)
Why: upstream merged prompt_modules as migration v8; the version
namespace is linear so the rebased task-sidebar work moves to v9.
Evidence: go vet + full go test ./... green; migration upgrade test now
walks v1<->v9 (up and down paths exercised for real).
Impact: fresh databases apply v8 (prompts) then v9 (conversation flags);
no released v8 conversation_flags ever existed, so no deployed database
can hold the old numbering.
Why: the task-centric sidebar (approved option A) needs a cross-project
conversation list, server-authoritative pinned/archived state, and an
identity endpoint for the sidebar account footer.
Evidence:
- migration v8 conversation_flags (sqlite/postgres up+down; the upgrade
test walks v1<->v8 for real); store and e2e tests cover pinned-first
ordering, archived filtering with ?archived=1, tenant-isolation
negatives (cross-owner flag write -> NotFound), and /api/me shape
(owner/name/auth) in embedded mode.
- go vet + full go test ./... pass.
Impact: additive columns/APIs; existing endpoints unchanged (PATCH gains
optional pinned/archived fields; responses keep prior shape).
Refs: core bump deps/agent-system-core -> 1dc08fc (Conversation flags)
Why: prompts lived inline in Go (profile const, subagent string, squad
role one-liners, tool descriptions) - every copy change shipped code,
and task guidance like meeting-minutes quality lived permanently in the
base prompt whether or not the task was at hand.
Evidence: new prompts package tests (library integrity, default
assembly, skill triggering incl. attachment gate and command bypass,
priority supersession, override chain drift, command match, frontmatter
parse); composite make test green; runtime check on a live server
(40 modules across 7 layers, override round-trip, /minutes starts a
run instead of hitting the command bus).
Impact: 40 builtin modules as embed data (5 base + 1 env + 12 task
skills + 10 agent roles + 7 tool descriptions + 3 aux templates + 2
styles); migration v8 adds prompt_modules for user overrides with
basedOnVersion drift markers; ctxasm assembles multi-segment system
messages with per-module observability; subagent/squad/tool copy now
resolve from the library with inline fallbacks; skill commands surface
in the / menu and route to runs; default profile SystemPrompt empties
onto the library base; pins deps/agent-system-core to the contract
commit.
Refs: feature/prompt-library task card; design guide in Documents.
Why: T3 of the interaction foundation - unify button/card/slash/chat entries onto one command bus (D27) composing the Agent-Command library (D30), with danger=high commands gated behind inline confirm cards and every dispatch leaving the same audit envelope.
Evidence: go test green - cmdbus suite (four-entrance audit symmetry, high-danger confirm lifecycle incl. cancel/expiry/handler-reject, audit-unavailable yields unknown, plugin spec fail-closed, schema scalar validation) and server e2e (danger command via POST /api/commands -> confirm card -> card action confirm -> committed receipt -> audit query ordered accepted->committed); legacy /help,/new,/mock,/model,/profile contract preserved through the bus; store migration v7 command_audit (both dialects) with roundtrip test updated.
Impact: new internal/cmdbus (L1 package per D33), server routes POST /api/commands/{id} + GET /api/commands/audit + registry-driven GET /api/commands, postMessage chat-entrance dispatch when the intent gate matches a registered command, plugins host OnCommands overlay, module cards policy/modules/{cmdbus,cardsvc}.md; pending confirm state is process-local (documented limitation).
Refs: docs/proposals/2026-09-30-ui-inbox-command-workspace.md T3; task card feature/command-bus-r1
Why: T2 of the interaction foundation — activity cards as first-class state
objects behind the right-rail inbox (proposal D25): upload ingest cards
(SR-A5 failures explicit, artifact retrievable), HITL projection cards
(double-presence, ref-linked two-way sync), squad orchestration cards and
the mock #upload demo of the full card lifecycle.
Evidence: go test ./... green across 14 packages incl. new cardsvc suite
(lifecycle, action labels and idempotency, pin/dismiss, owner isolation,
resolve-by-ref idempotency) and updated migration test (v6 activity_cards,
both dialects); events flow through the session event buffer (persist, seq,
replay); receipts appended to the conversation timeline on card actions.
Impact: additive; cards disabled (SetCards nil) degenerates to the T0
baseline; upload cards persist at project level per the v1 inbox boundary
(conversation-scoped inbox; project-level aggregation is follow-up).
Refs: modules/documents docs/proposals/2026-09-30-ui-inbox-command-workspace.md
Why: backend main pinned core 019617e (unfetchable post-migration) and the
store List* functions returned nil slices that encode as JSON null, which
crashed the frontend nav with .map on null (the 2026-09-30 white-screen).
Evidence: go test ./... across all packages; store regression
TestEmptyListsSerializeAsEmptyArrays asserts [] for empty project lists.
Impact: all 17 store list sites now initialize empty slices; build-blocker
core pin resolved; frontend no longer receives null for empty lists.
