ARCHITECTURE.md:183
- The M2 manager-request endpoint does not persist a request record.
CreateMyClaManagerRequestgenerates an ID, sends email, and records a best-effort audit event; the M2 brief explicitly says no request record is persisted. This contract would lead consumers to expect a lifecycle that only the separate M3 manager-request APIs provide.
| `POST /v4/my-clas/{signatureID}/cla-manager-requests` | M2 | emails an approval/removal/contact request; writes a request record + audit event, **never signature state** |

- This M3 contract inventory is already stale. The repository now implements and documents
GET /v4/company/external/{companySFID}/cla-groups, the manager-request list/get/approve/deny routes, andPUT /v4/cla-group/{claGroupID}/ecla/{signatureID}/invalidateindocs/M3_ORG_LENS_API.md. Add these settled routes to this roll-up and link that API reference; otherwise an M3 integrator misses required calls and is incorrectly directed only toMY_CLAS_API.md.

Add a root ARCHITECTURE.md describing the target architecture of the EasyCLA -> LFX Self Serve migration through M3: cross-component contracts, authorization, and external dependencies. It is a roll-up of the reviewed decision record in docs/easycla-ss-migration, not a replacement for it, and deliberately does not describe EasyCLA's internal design. Only M1-M3 are covered as target architecture; M4 and M5 are recorded as not planned. "Implemented" is stated throughout as merged and dark-launched behind a LaunchDarkly flag, not as serving production traffic. Guard the file with a CODEOWNERS entry for the LFX architecture team, and link it from README.md. Verified against shipped code on origin/dev: all eight documented endpoints exist in cla.v2.yaml; the five documented statuses match those the backend produces (no superseded/expired); the PDF route returns NotFound; PresignedURLValidity = 15 min; activeSignatureTTLDays = 1.

ARCHITECTURE.md:81
- This describes only the secured gateway chain, but the decision record explicitly notes that several v4 paths use the public router and bypass JWT/ACS entirely. As written, an integrator could incorrectly assume every v4 route receives an ACS decision and injected scopes; qualify the layer and call out the public-route exception.
**Layer 1 — lfx-gateway.** Validates the JWT's **signature and issuer only** (the **audience check is
explicitly disabled**), calls the ACS warden with username/path/method, 403s on denial, and injects a
base64-encoded `X-ACL` plus `X-Username`/`X-Email`.
ARCHITECTURE.md:153
- The browser does see a raw EasyCLA user ID in the shipped M2 flow. Self Serve's
POST /api/me/clas/prepare-signreturnsPrepareSignResponse.userId, populated directly from the upstream result, even though the component currently only usessignUrl. Narrow this claim to the list adapter or document the prepare-sign exception.
pattern), so an M5 re-platform has a single adapter to rework. The browser never sees raw EasyCLA user IDs.
ARCHITECTURE.md:170
- The M3 contract inventory is already more settled than this note indicates, and the linked M3 brief does not enumerate the new paths.
docs/M3_ORG_LENS_API.mdrecords dev-validated contracts for the org posture read, four manager-request lifecycle operations, and ECLA invalidation, all present in the current swagger. Omitting them from this roll-up—or at least failing to link the actual API inventory—leaves M3 integrators without the current contract map.
**M3's inventory is not yet complete.** Beyond the endpoint above, the org lens absorbs the Corporate
Console's existing v4 operations (approval-list CRUD, employee acknowledgements, CLA-manager
add/remove/designee, signed-CLA and activity views) plus the v3 org search and CLA metrics its BFF aggregates.
Those stay enumerated in the [M3 brief](specs/001-easycla-ss-integration-fable/03-milestone-ccla-org-lens-fable.md)
until settled.
ARCHITECTURE.md:187
- These are M2-only guardrails, not guarantees through M3. The M3 backend already exposes
POST /v4/self-serve/request-corporate-signature, which creates a DocuSign envelope/signing session, andPUT /v4/cla-group/{claGroupID}/ecla/{signatureID}/invalidate, which mutates signature state. Keeping the current wording directly contradicts the contracts above and the M3 API reference.
- SS runs **no signing ceremony** and makes **no signing-initiation calls**; `prepare-sign` only prepares the
hand-off.
- SS makes **no invalidation writes of any kind** (legal decision, 2026-08). Invalidation is a CLA-manager

ARCHITECTURE.md:42
- The backend is not unchanged through M3: the M3 work adds multiple v4 operations, including the self-serve corporate-signature endpoint listed below. If this means the deployment/data architecture remains in place, state that instead so integrators do not infer that no backend work is required.
subgraph backend["EasyCLA backend (unchanged through M3)"]
ARCHITECTURE.md:186
- This is an M2-only guardrail. M3 explicitly adds
POST /v4/self-serve/request-corporate-signature, which starts the CCLA signing flow and creates a real DocuSign envelope; saying no signing-initiation calls hold through M3 directly contradicts the contract above.
- SS runs **no signing ceremony** and makes **no signing-initiation calls**; `prepare-sign` only prepares the
hand-off.
ARCHITECTURE.md:174
- This field-level pointer covers only the My CLAs/M1–M2 contracts; it does not document the M3 endpoint in the same table. The implemented M3 request/response, authorization, and side effects are documented in
docs/M3_ORG_LENS_API.md, so link that reference here as well.
Field-level detail: [docs/MY_CLAS_API.md](docs/MY_CLAS_API.md). The status a row shows and the actions each
status permits: [docs/MY_CLAS_STATUS_MATRIX.md](docs/MY_CLAS_STATUS_MATRIX.md) — the single source of truth
SS renders against.
The claim that user-service and org-service "are being deprecated" had no source outside P9 itself. org-service is live and in use today (its repo deploys to prod, lfx-gateway routes it, lfx-self-serve calls organization-service/v1/orgs/search), and no lfx-v2-* architecture doc states it is being retired. It is not attributable to the 2026-07-20 architecture review: unlike P2 and P10, P9 carries no date, ticket, or confirmation, and the one sourced statement nearby (ARCH-406) says a user-service endpoint stays. - P9: user-service deprecation stated as anticipated; org-service noted as having no announced deprecation. The load-bearing guidance is unchanged -- SS must not hard-depend on v1 IDs it cannot resolve later. - Dependency table: "deprecation planned" -> "v1 IDs may not remain resolvable".

Address review comments from copilot-pull-request-reviewer, coderabbitai:
- ARCHITECTURE.md: qualify the "browser never sees raw EasyCLA user IDs"
claim. M2's prepare-sign returns a signUrl of the form
/#/cla/project/{claGroupID}/user/{userID} (v2/self_serve_sign/service.go),
which the browser navigates to, so the absolute claim was wrong.
- ARCHITECTURE.md: scope the no-signing-initiation and no-invalidation
guardrails to M2. M3 absorbs the Corporate Console's manager-facing
operations, which include server-side CCLA signing initiation
(request-corporate-signature, already listed in the contracts table) and
manager-initiated ECLA invalidation. Stating them program-wide would tell
M3 implementers to omit required operations.
- ARCHITECTURE.md: use "Approved List" consistently (CLAUDE.md convention).
- CODEOWNERS: correct the access note -- GitHub requires write access for a
code-owner team, not read, so the previous note understated what an admin
must grant for the guard to fire.

Previously missed (1) — in code that hasn't changed since the last review.
ARCHITECTURE.md:81
- This describes the secured chain as universal, but the gateway has an explicit public router that bypasses JWT validation, ACS, and header injection for multiple v4 paths (for example
request-individual-signature,notify-cla-managers, designee checks, and CLA-manager list reads). Since this is the authorization overview and M3 consumes some existing operations, qualify Layer 1 as applying only to non-public routes.
ARCHITECTURE.md:153
- The shipped M2 hand-off does expose raw EasyCLA user IDs:
PrepareSignreturnsuserId, Self Serve passes that field to the browser, andsignUrlitself contains/user/{userID}. Remove this invariant or document the hand-off exception so consumers do not rely on an inaccurate boundary.
All integration goes through **one SS server-side `cla` module**, so an M5 re-platform has a single adapter
to rework. API responses carry no raw EasyCLA user IDs — with one exception: M2's `prepare-sign`
ARCHITECTURE.md:183
- These are M2-only guardrails, not guarantees through M3. The M3 Self Serve endpoint delegates to
RequestCorporateSignatureand creates a real DocuSign envelope, while the new ECLA invalidation endpoint setssignature_approved=false(docs/M3_ORG_LENS_API.md:35-53,68-80). As written, this section contradicts the M3 contract already listed at line 164.
### Guardrails
The first two are **M2 scope**, not program-wide: M3 moves the Corporate Console's manager-facing operations
into SS, which includes both server-side CCLA signing initiation

ARCHITECTURE.md:218
- The finalized M3 tickets establish a production rollout dependency that this table omits: every new M3 path needs an ACS resource/policy registration and per-environment
acs-cli sync, because production default-denies unregistered paths even though development forwards them. Without this distinction, an endpoint can pass dev testing and consistently return 403 in production.
| **lfx-gateway** (Traefik) | routing + layer-1 authorization | EasyCLA is already behind it; nothing to onboard |
| **ACS** (LFX v1) | CLA role+scope truth | async assignment; ~30-min authorize cache; one-company-at-a-time grants |
ARCHITECTURE.md:171
- The finalized M3 backend plan now adds several concrete contracts beyond the signing endpoint, and it explicitly says Self Serve consumes v4 only. Leaving this as “not yet complete” while referring to v3 org search makes the architecture artifact stale and omits the org-posture read, manager-request lifecycle, ECLA invalidation, and sanctions-write contract that M3 integrators must implement.
**M3's inventory is not yet complete.** Beyond the endpoint above, the org lens absorbs the Corporate
Console's existing v4 operations (Approved List CRUD, employee acknowledgements, CLA-manager
add/remove/designee, signed-CLA and activity views) plus the v3 org search and CLA metrics its BFF aggregates.

The dependency row claimed EasyCLA has "nothing to onboard" behind lfx-gateway. Verified against the sibling repos that this is wrong for new operations: - lfx-gateway/dynamic/services/cla-service.yaml defines two routers: an explicit unauthenticated PathPrefix allow-list, and a blanket `cla-service-secured` (jwks + acs) catching everything else. New operations correctly fall to the secured router. - acs-cli/services/11-cla-service.yaml registers each operation individually as an ACS resource + permission. All M1-M3 endpoints have entries; an unregistered path 403s in production. - M1/M2 resources are anyRole: true; M3's self-serve/request-corporate-signature is anyRole: false over objectTypeIDs [organization], so it also needs an org-scoped role assignment. Per review feedback on PR #5196 (flagged by copilot-pull-request-reviewer). Signed-off-by: Michal Lehotsky <mlehotsky@linuxfoundation.org>
Verified against acs-cli sync/resources.go: buildResourcePayload never sets object_type_id on the create path, so POST /v1/api/resources always lands as the server default type regardless of the YAML declaration. Registering an operation in 11-cla-service.yaml is necessary but not sufficient -- a manual PUT + cache flush is required, as already documented in docs/M3_ORG_LENS_API.md's dev rollout notes. Dropped the anyRole/organization object-type claim for M3's self-serve/request-corporate-signature resource: the YAML declares organization but M3_ORG_LENS_API.md records dev was hand-fixed to project, and I can't confirm current prod state either way -- the verifiable defect is the sync bug itself.

The LFX convention for
ARCHITECTURE.md: a roll-up of current-state cross-component contracts, authorization, and external dependencies — what someone outside this repo needs in order to integrate with it or review a change to it. It is explicitly not internal repo design; CLAUDE.md covers repository layout and the module pattern, and docs/MY_CLAS_API.md is the endpoint reference.Scope is the migration through M3, the last planned milestone. Content is summarized from the already-reviewed decision record (
architecture-proposal.mdP1–P10, reviewed 2026-07-20, P10 approved 2026-07-28;role-mapping-feasibility.md) and links back to it rather than superseding it — those remain the audit trail.Citations name files and symbols, not
file:line. Line numbers do not survive ordinary refactoring, and a stale line number in an architecture doc is worse than no citation.Sections

"Implemented" ≠ live. M1 and M2 are both merged and dark-launched behind LaunchDarkly flags. The doc states this at the milestone table rather than letting "implemented" imply production traffic.
The trusted-caller path (P10) is deployed but inactive, and the doc says why it cannot simply be switched on: SS's
apiGatewayTokenis the same token SS hands to every logged-in user asv1TokenviaGET /api/profile/developer, so allow-listing that client ID would let any user assert any identity. Activating P10 needs a distinct server-only token first.No issue list. Known architectural tensions are recorded because they constrain M3 design — two stores of CLA-manager truth, uneven enforcement across v4 write paths, structural UI/enforcement drift from the ~30-minute ACS cache, and M3's hidden ~648-file GraphQL BFF. Actionable findings are tracked as separate tickets, not here.
The doc also states the consequence of M4/M5 being unplanned: anything described as "until M5" should be read as indefinite.
