Why: the U4 branch is 89 commits behind main, which now carries the shared
document renderer, two-trees project work, the SQLite instance guard and
exec env layers (PR #209 merged as c76d8bd); it conflicted in storage
migrations, host capabilities and the extension surface. The user authorized
syncing U4 after the renderer line on 2026-10-18.
Evidence: content is the agent-exec transport 3b64eb5 (cursor worker, unit
backend-iam-u4-onto-main-c76d8bd-r1, run on a checkout whose tree equals main,
receipt /tmp/cleanup-20261018/render/u4-backend-onto-run.json, SELF). Host
check: main migrations 1-48 unchanged (migrate.go has no deleted lines versus
main), U4 migrations moved from 35-36 to 49-50 with identical SQL,
surface.txt is the sorted union, deps stay at main's pins.
Impact: databases that ran unmerged U4 builds with the old numbering must be
recreated. SurfaceVersion becomes 2.25.0-experimental. Main's admin password
account creation now requires the system.users.create action like the other
U4 account writes.

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Impact: Keep exec_env_layers at schema v35, move the feature migrations to v36-v46 in order, and fail closed on the old unpublished numbering.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: The sandbox hides the host home directory and has no network, so pip install --user cannot supply python-docx, and the service PATH resolved python3 to a linuxbrew path that does not exist inside the sandbox.
Evidence: SELF go test of execenv, tools, store, app, server, runmgr, config, and cmd/agent-system on this worktree. CI has not run.
Impact: Sessions inherit a read-only base layer. Extra packages are requested through python_env, auto-approved only from the allowlist, and mounted per conversation. Schema 35 adds the request and binding tables.
Refs: .task/feature-layered-python-env.md
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: A failed completion-card write could strand durable results, and routed messages could discard a selected result reference.
Evidence: Regressions cover missing projection recovery without execution, unavailable saved runs, pre-child dispatch failures and existing work/authorization paths.
Impact: Reconcile terminal saved results on authorized reads, keep known failures visible, and route explicit references through the conversation context.
Refs: feature/workbench-flow-completion review reliability and API findings
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: A generic conflict response hid whether source intake, authorization, or risk analysis blocked a formal command.
Evidence: The server suite passes with bounded domain reasons included in the conflict response.
Impact: Clients can present the actionable gate reason without exposing source contents.
Refs: TT-N03 TT-R01
Why: Direct HTTP and surface command dispatch could mutate RDM project facts without an analyzed committed-message manifest.
Evidence: Command-bus, server, and app suites pass with a classification regression for formal writes and read/proof exceptions.
Impact: Formal HTTP writes require a conversation anchor and committed proceed decision; surface writes fail closed until they can carry the same proof.
Refs: TT-N03 TT-R01
Why: The W4b verifier branch must include the current compiled-plugin host option surface before review.
Evidence: Focused extension, app, server, and command-bus tests pass after preserving both public API additions.
Impact: The public surface advances to 2.23.0-experimental and exposes both human-decision and compiled-plugin capabilities.
Refs: W4b human decision verifier
Why: A model-visible flag cannot prove that a person confirmed one proposal revision and payload hash.
Evidence: go test ./pkg/extension ./internal/app ./internal/server -run 'HumanDecision|SurfaceSnapshot|ResolveHuman|NaturalLanguage' passed locally.
Impact: SurfaceVersion 2.22.0-experimental adds HumanDecisionVerifier. Existing Host methods stay unchanged, and the base does not consume the proof.
Refs: W4b human confirmation design r1
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: Independent review found delegated account actions, stale resource policy, and role migration cutover gaps in the initial U4 implementation.
Evidence: Backend full SQLite suite passed; isolated PostgreSQL role and migration suite passed; independent final review found no remaining findings.
Impact: Enforces transactional system grants, current role snapshots, staged role import with v36 migration, and fail-closed activation.
Refs: feature/iam-u4-role-authority
Why: Non-root managers need the system-management entry and controls to follow their explicit grants.
Evidence: The full Backend test suite passed and /api/me action projection is covered by the grant-isolation test.
Impact: /api/me now returns only the current actor system actions evaluated by the same authorizer.
Refs: Focused role and permission system task 7
Why: System, role, and project entry permissions need explicit actions instead of a single administrator flag or unrestricted project creation.
Evidence: The full Backend test suite passed, including role APIs, action isolation, project.create denial/allow, storage migration coverage, and account write fences.
Impact: Adds versioned role and grant endpoints, maps account actions to explicit permissions, and requires project.create authority.
Refs: Focused role and permission system task 3
Why: a composed base binary must apply plugin startup defaults and plugin-owned flags without a downstream main.
Evidence: go test ./pkg/extension/ ./cmd/agent-system/ -count=1 (SELF, this commit's parent tree plus these files).
Impact: blank-imported plugins can set HostOptions and a CLI hook; GET /api/registry gains a compiled id list; explicit serve flags still win.
Refs: plugins/registry compose deploy
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: Merging run-process visibility introduced a read endpoint that bypassed U3 effective-account checks when authentication was off.
Evidence: A new regression first returned HTTP 200 for disabled local; with entry and final response checks it passed, and the event pagination test passed ten repeated runs after anchoring to its appended event sequence.
Impact: Explicitly disabled local accounts cannot read stored process events; missing implicit local remains compatible.
Refs: IAM U3 Stage 8 integration review; Backend PR #198; main PR #199
Why: Completed replies currently drop access to streamed thinking and tool output.
Evidence: go test ./...; isolated run-event pagination and conversation binding test.
Impact: Add owner-scoped paginated event reading for a single conversation run.
Refs: Agent-System-Dev feature/work-companion-visibility UI1
Why: Account disable could be followed by late Backend business writes, API key creation could implicitly create users, account bootstrap locks could invert, and directory cursors were process-local or leaked out-of-scope changes.
Evidence: Local go test ./... and isolated PostgreSQL package suites passed on the staged candidate; exact committed-head SELF replay and stage 6 human review remain pending.
Impact: Adds final account transactions and external-effect checks across HTTP, Host, Bus and run manager; tightens API key issuance and persists versioned cursor signing. Delegated RDM rename still needs the separately proposed real-operator contract, so A1 and stage 6 are not complete.
Refs: Documents U3 r1, approved A1-A4 amendment fb3a821, pending delegated-projection amendment 5783940, Dev feature/iam-u3-account-directory-recovery.
Why: Administrator-issued password and login-key paths could take over target accounts, while old credentials and plugin handles ignored current account state.
Evidence: SELF receipts /tmp/iam-u3-backend-all-replay.json, /tmp/iam-u3-backend-final-pg-core.json, /tmp/iam-u3-backend-build.json, and focused HTTP/concurrency receipts in /tmp/iam-u3-*.json.
Impact: Adds trusted pending-account initialization and reissue, preexisting owner-session proof, proposal/rotation/grant transactions, server-side admin search, current Host guards, and legacy HTTP/CLI closure. Production cutover and downstream pins remain pending.
Refs: IAM U3 r1 stages 4-5; Dev feature/iam-u3-account-directory-recovery
Why: Disabled accounts and mixed credentials could continue to authenticate, while web creation accepted passwords and administrator privileges.
Evidence: SELF receipts /tmp/iam-u3-u2-store-sqlite-green.json, /tmp/iam-u3-u2-store-pg-regression.json, and /tmp/iam-u3-u2-server-sqlite-green.json.
Impact: Adds versioned enable/disable, revokes existing handles, protects the last operable manager, and exposes pending-account/profile APIs. Recovery proposal and legacy-entry closure remain in U3-4.
Refs: IAM U3 r1 stages 4-5; Dev feature/iam-u3-account-directory-recovery
Why:
Legacy project streams replayed upload filenames and parser metadata to newly
authorized members even though the underlying cards remained owner-only.
Evidence:
SELF real HTTP red regressions exposed legacy replay, spoofed sharing claims,
private-history pagination, and live delivery after membership removal. The
affected packages, uncached full Backend suite, isolated PostgreSQL Store suite,
and agent-system build pass after applying the event boundary.
Impact:
Registered lifecycle streams resolve trusted resource ownership and require an
internal publication proof for cross-owner delivery. Event and proof commit in
one transaction; v30 adds an additive SQLite/PostgreSQL sidecar without granting
access to historical events. Seen and visible cursors remain separate, revoked
members leave live streams, and unregistered base behavior remains compatible.
The storage migration tool preserves the new proof rows.
Refs:
project-member-access-implementation-plan.md Task 1 / R5; authorized legacy SSE
privacy follow-up; project-member-composed-legacy-project-history.json
Why:
Nested unchanged credential masks left empty parents that looked like managed
subtree overwrites. Shared members also hit an owner-only upload guard, while
upload ingestion cards could disclose private filenames and parser metadata.
Evidence:
SELF independent nested-mask probe, HTTP nested/mixed writeback, member upload,
project card privacy and authorization-change regressions failed before each fix
and passed after it. Affected settings/server suite passed; exact final-object
build and independent replay remain delivery gates owned by the task coordinator.
Impact:
Prune only parents emptied by ignored masks; explicit empty/real managed writes
stay rejected. Registered uploads check live work and trusted project existence,
keep originals owned by the actor, and recheck before persistence. Suppress only
upload project cards when no private stream exists; explicit structure cards and
unregistered upload behavior remain available.
Refs:
Dev project-member-access plan r1 Task 1/R5; independent nested mask P2;
2026-10-13 composed member-upload and private project-stream acceptance findings
Why:
Legacy project metadata can contain credentials outside the settings scope table.
Sharing raw projection settings exposed them, and generic project PATCH bypassed
the system-managed path guard already enforced by project settings endpoints.
Evidence:
SELF member Host regression failed before the fix. The fixed 4f72aaf server
baseline overlay reproduced HTTP metadata leakage and managed PATCH returning 200.
SELF shared Host-to-HTTP, immutable mask, dotted/schema/fallback, public mutation
and atomic managed-write regressions passed; uncached full suite, isolated PG
Store suite and static build passed. Independent delta replay remains a gate.
Impact:
Registered lifecycle metadata returns detached credential-masked views while
preserving service/configuration keys and persisted data. Generic project PATCH
shares the existing managed validator before rename or settings mutation; allowed
metadata key shapes and raw owner-only management lookups remain available.
Refs:
Dev project-member-access plan r1 Task 1 and R5; approved hard secret boundary;
2026-10-13 shared project metadata review follow-up
Why:
Shared project reads previously doubled as write permission, project mutations
bypassed the domain lifecycle, and coarse retrieval shared private resources.
Evidence:
SELF red-before-implementation logs cover projection, lifecycle, private work,
resource filtering, canonical retrieval scope, publication source and namespace.
SELF go test ./..., isolated PostgreSQL go test ./internal/store -count=1,
and CGO_ENABLED=0 go build ./cmd/agent-system passed; task owner owns replay/CI.
Impact:
Add optional actor-scoped projection/lifecycle capabilities; registered providers
control public lifecycle and live work. Preserve owned conversation history and
ordinary unregistered behavior. Authorize knowledge by stored ID/source, map
current host scopes through trusted service metadata, and filter artifact lists.
Refs:
Dev project-member-access implementation plan r1 Task 1; approved design r0.1;
2026-10-13 trusted publication Source hardening ruling
Why: The login recovery contract leftovers and KTD12/KTD14 require:
concurrent same-name account creation must not overwrite the winner,
first-admin bootstrap must serialize across processes, the redeem
endpoint backoff must be shared across instances, revoked API keys
must close established SSE streams, and CLI credentials need an
env-DSN path plus a non-interactive 0600 file delivery mode.
Evidence: go test ./... green; new tests cover 16-way concurrent
create (1 win/15 conflict, winner credentials intact), 8-way
concurrent bootstrap (single admin, refuse takeover after), redeem
guard shared across two store handles on one DB, SSE stream closed
after key revocation within the recheck window, and HTTP 429 after
the failure cap (SELF worktree run; CI is the GATE, PG via test-pg).
Impact: Migration v29 (redeem_attempts); CreateAccount becomes a
single-row INSERT with unique-violation conflict; BootstrapFirstAdmin
advisory-locks (PG) / rechecks (SQLite) and commits admin+key+audit in
one transaction; SSE revalidation covers API-key streams; redeem
backoff moves to the shared DB; CLI gains AGENT_SYSTEM_DSN fallback
and --out file delivery for create/reset-password/issue-login-key/
bootstrap-admin.
Refs: docs/svc-deploy/2026-10-13-login-recovery-contract.md leftovers;
proposal r2 KTD12/KTD14/R5/R11.
Why: The 2026-10-13 login recovery contract (Dev docs/svc-deploy/
2026-10-13-login-recovery-contract.md, plan item 6.7) requires that
established SSE connections stop receiving private events once a
password write destroys their session.
Evidence: go test ./... green; TestSSESessionInvalidationClosesStream
streams over a real HTTP server, invalidates the session via
AdminResetUserPassword, and asserts the stream terminates with the
session-expired marker within the recheck window (SELF, worktree run).
Impact: Session-authenticated event streams revalidate at a 15s
heartbeat cadence (package var, shortened in tests) and terminate on
invalidation; API-key streams are unchanged (key revocation is separate).
EventSource reconnects are rejected by the auth middleware.
Refs: Dev PR #504; login recovery contract section 6.7.
Why: The login recovery contract (2026-10-13) requires admin-issued
one-time keys, in-transaction revalidation of restricted sessions, a
login race guard, and audited password writes; the previous
implementation validated sessions outside the change-password
transaction and let stale password verifications create sessions.
Evidence: go test ./... green (SQLite); store tests switch to
openTestStore so the CI test-pg job covers real PostgreSQL, including
100-way concurrent redeem single-winner and auth-version race cases
(SELF, local run).
Impact: New migration v28 (users/sessions.auth_version,
account_events). New admin endpoints POST/GET
/api/admin/users/{owner}/login-keys and DELETE
.../login-keys/{id}. Login binds session creation to the verified
auth version and creates restricted sessions for must-change accounts;
redeem gains per-IP backoff; cookies gain Secure under TLS; active
change-password and admin/CLI resets become single transactions that
bump auth_version, revoke keys and sessions, and write audit events.
Refs: modules/documents/docs/proposals/2026-10-12-svc-unified-deploy-and-login-key.md r2; Dev task feature/svc-login-recovery-flow
Why: passwordless activation/recovery must redeem only into a
set-password session; account ops must not create empty stores.
Evidence: SELF go test store/server login-key and OpenExisting cases.
Impact: auth middleware gates; CLI user create defaults to activate key.
Refs: docs/svc-deploy/u4-one-time-login-key.md

Why: Generative UI U5 left the B-class action allowlist empty; owner
authorized first entries builtin.help and system.intent.
Evidence: go test ./internal/genui/ ./internal/surfacesvc/ ./internal/server/
Impact: Surface buttons may bind help/intent; button-entrance intent
matches only and does not nest-dispatch write commands.
Refs: docs/proposals/2026-10-12-generative-ui-bclass-help-intent.md
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: the admin zone could not host plugin-declared partitions - KTD4
requires the RDM audit partition to be reachable by RDM domain admins and
base superadmins without hardcoding RDM into the base AdminZone.
Evidence: go test ./internal/app ./internal/server ./pkg/extension green
incl. new admin-zone recording/endpoint tests; surface snapshot test
green after surface.txt update; CI (Dev composite) is authoritative.
Impact: extension surface 2.8.0 -> 2.9.0 (Registry.AddAdminZone +
AdminZoneSpec, fail-closed on invalid specs); applyCompiled records
declarations into the plugin summary; new authenticated GET
/api/admin-zone/sections returns the flattened, ordered declaration list.
Entry visibility stays metadata-only - data capability remains enforced
by each section's own command surface (fail-closed).
Refs: WP3-I3/KTD4; task card feature-adminzone-plugin-sections.
Why: two-process HTTP acceptance (Dev tests/integration/multi-instance, added in
the matching Dev-side change) exposed three real cross-instance defects that the
U5 library-level tests bypassed via direct Manager calls, plus the U7 fault
matrix needs explicit disk-full rejection evidence.
Evidence: go test ./... green on SQLite and real PG (AGENT_PG_TEST_DSN);
new regressions TestCrossInstanceResolveDoesNotSettleCard (runmgr, PG-gated),
TestUploadRejectsCleanlyWhenObjectDirUnwritable and
TestArtifactOverwriteRejectsCleanlyWhenObjectDirUnwritable (server).
Impact: ResolveHITL no longer settles the card when the run executes on another
instance (command-bus fallback stays available); cancelRun enqueues the command
with the real conversation id and no longer reports a false local success;
object-store failures now provably leave zero DB/object residue.
Refs: collaboration storage proposal U7 (sections 3/5/7); task card
feature/u7-load-fault-release.
Why: U6 extends pages from conversations into the task/project
workspace - surfaces aggregate across conversations under the owner's
project scope (project resolved authoritatively from the conversation
row, never self-reported by the model), and the catalog guidance now
organizes pages by task phase (requirements/execution/acceptance)
while stating that task facts come only from real task records.
Evidence: build/vet clean; surfacesvc suite green incl. the new
project-aggregation test (owner isolation, cross-owner zero, history
retained post-disable); genui/store suites green.
Impact: New endpoint GET /api/projects/{id}/surfaces; Submit resolves
project from conversation; catalog text guidance. Existing endpoints
unchanged.
Refs: proposal r2 U6; Dev task feature/generative-ui-u6
Why: compiled-in plugins (generative-ui, rdm) never appeared in the admin
plugins list: GET /api/plugins only scanned the directory host, so binary-
level capabilities were invisible to operators (user-reported gap).
Evidence: go test ./internal/app/ ./internal/server/ green locally incl.
new TestApplyCompiledRecordsSummary and TestListPluginsMergesCompiled;
CI (make test) is authoritative.
Impact: applyCompiled records each plugin's registered commands/intents/
skills into a summary handed to the server; /api/plugins merges synthesized
inproc entries (backend.mode=inproc, apiVersion=extension surface version,
provides from the registration record). Directory entries win on id
collision. No public extension-surface change.
Refs: WP3-I4; task card feature-plugins-compiled-listing.
Why: The approved U5 scope needs the action half of the loop: an
idempotent ledger (migration v24), a single-choke SubmitAction (plugin
activation, current-revision, action whitelist, params-hash
idempotency), dispatch through the command bus so DangerHigh lands on
the existing inline confirm card with no Confirmed passthrough (the
endpoint does not even bind the field), the button-only
generative-ui.submit storing form data in the plugin KV ledger, and
catalog discipline rejecting unknown action ids at present time.
Evidence: go build/vet clean; full go test ./... green; surfacesvc/
genui/store suites also green under AGENT_PG_TEST_DSN; red matrix
covers disabled/stale-revision/cross-owner/unknown-action/idempotent
same-and-different-params/danger-high-await-confirm and the endpoint
forged-confirmed case.
Impact: Additive migration v24 + new endpoint/command; existing
endpoints and command semantics untouched (B-class whitelist starts
empty per the approved scope).
Refs: U5 action-scope r2 (approved, Documents #71); UI #46/#47;
Frontend #56; Dev task feature/generative-ui-u5
Why: a browser holding a revoked API key in localStorage sent the Bearer
header on every request; key precedence 401'd all APIs despite a valid
login session, locking admins out of user management. /api/me also
reported mustChangePassword for key principals, who cannot change
passwords (session-owned), dead-ending the forced-change gate.
Evidence: new TestStaleKeySessionFallback covers fallback and authVia;
TestAuthMiddleware/TestAdminAccountFlow unchanged and green; full
go test ./... green.
Impact: invalid key falls back to a valid session cookie before 401
(cookie-less programmatic clients unaffected); /api/me gains
authVia ("key"|"session"|""), letting the frontend keep key holders
out of the change-password gate.
Refs: Dev task feature/admin-auth-gate-fix.
Why: plan U5/KTD4+KTD5 - before a second instance may serve writes, conversation execution must have a single valid owner (DB lease, epoch increments on takeover), stale owners must not settle (in-transaction fence check), and cancel/HITL must reach the executing instance via a persistent command inbox.
Evidence: full suite green twice-relevant on SQLite and real PostgreSQL 18.6 (35 packages each tier) - lease tests (claim/contention/re-claim/renew fencing/expiry takeover/monotonic epoch, command inbox idempotent enqueue, atomic concurrent claim) and multi-instance tests (same-conversation contention rejected, stale-owner settle fenced with run unchanged, cross-instance cancel consumed exactly once by the owner instance, non-owner does not consume).
Impact: v23 migration (conversation_executions + run_commands); ClaimConversation stacks a DB lease on PG tiers (15min, release on conversation release); settle path fenced (fenced runs emit run.fenced, no terminal write); StartCommandConsumer polls the inbox for commands on locally-owned executions (cancel routes to local cascade or DB-level close-out; HITL revalidates gate and rejects expired explicitly); server cancel/HITL fall back to command enqueue with 202 when the run is not local; app wires instance identity (host:addr on PG tiers) and starts the consumer.
