P1 [CRF-1] Committed generated doc uses a ```shell code fence where make gen emits ```sh, so the gen CI job fails deterministically. (Netero)

make gen GEN_SKIP_GOLDEN=1 leaves exactly one dirty file:

 M docs/reference/api/members.md
-```shell
+```sh

This is the only ```shell block in docs/reference/api/ (every other endpoint and every regenerated block uses ```sh), which confirms the section was hand-edited or produced by a stale generator. Run make gen and commit the result to turn the gen (88271000618) job green.

Fixed in 69e5d6fc06. Ran make gen, which produced exactly the ```shell → ```sh diff, and committed it. The gen job should now be green.

P3 [CRF-2] The OIDC org-sync validation in postOrganizationMembers duplicates the predicate and near-identical error message already in manualOrganizationMembership. (Netero)

manualOrganizationMembership (members.go:742) is the single-user gate: user.LoginType == LoginTypeOIDC && api.IDPSync.OrganizationSyncEnabled(...) plus a user-facing message. The batch handler reimplements the same predicate and re-authors a plural variant of the same message strings inline.

The aggregate reporting (collect all offenders, resolve the feature flag once) justifies not calling the single-user helper as-is, but the predicate and message copy will drift from the canonical version when one side is edited. Factor the shared check and message so both paths stay in sync.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Addressed in 9126b51743. Factored the OIDC org-sync block copy into a shared manualMembershipBlockedResponse(usernames []string) helper. Both manualOrganizationMembership (single) and postOrganizationMembers (batch) now route through it, so the message/detail wording can't drift; the helper pluralizes based on the number of blocked users. The batch handler still resolves the feature flag once and aggregates offenders.

Note [CRF-4] No test covers duplicate user IDs within a single request. (Netero)

GetUsersByIDs dedupes, so the missing/deleted checks pass, and the UNNEST(...) ON CONFLICT DO NOTHING insert receives duplicate user_id values. members_test.go covers OK, already-member, not-found, single, skip-existing, deleted, and audit-count, but not UserIDs: [x, x].

Postgres ON CONFLICT DO NOTHING tolerates in-statement duplicates, so behavior is expected to be correct, but the path is unverified. A one-line subtest would close the gap.

🤖 Comment by Coder Agents on behalf of Jake Howell

Added TestAddMembers/DuplicateUserIDs in 9126b51743. It sends UserIDs: [x, x] and asserts a single insert with no error, confirming GetUsersByIDs dedup + ON CONFLICT DO NOTHING handle in-request duplicates.

P3 [CRF-8] The batch InsertOrganizationMembersBatch authorization preamble is a verbatim copy of the singular InsertOrganizationMember, and the two have already drifted. (Pariston P3, Ryosuke P3, Razor P3, Robin P3, Knov P3, Zoro P2)

Lines 6236-6258 (convertToOrganizationRoles -> GetOrganizationByID -> default-role expansion -> canAssignRoles) are line-for-line identical to 6204-6226. The only intended difference is the return type; the unintended one is that the singular path authorizes ResourceOrganizationMember.InOrg(org).WithID(arg.UserID) (6231) while the batch drops .WithID (6263).

Six reviewers flagged this independently. This is security-sensitive authorization logic in two hand-maintained copies: the next tightening of canAssignRoles or the role model lands on one path and silently skips the other. Kurapika verified the current .WithID divergence (prior CRF-7) is harmless (the batch check is equal-or-stricter, never looser), so this is a latent maintenance hazard rather than a live bug. Fix: extract a shared authorizeOrgMemberInsert(ctx, orgID, roles) helper both wrappers call, so they diverge only at the final authorizeContext object and the .WithID choice becomes a deliberate, visible decision. Zoro rated this P2 for the security-sensitivity; set at P3 because there is no current authorization impact.

Done in c61b66d388. Extracted authorizeOrganizationMemberInsert(ctx, orgID, roles), shared by both InsertOrganizationMember and InsertOrganizationMembersBatch. They now diverge only in the final authorize object, so the .WithID difference is a deliberate, visible one-liner in each wrapper and the role-assignment preamble can't drift.

Nit [CRF-22] The two chained append calls plus the //nolint:gocritic suppression can be one slices.Concat. (Ging-go)

append(orgRoles, ...); addedRoles = append(addedRoles, defaultRoles...) appends into orgRoles' backing array, which is what trips gocritic's appendAssign and forces the //nolint. slices is already imported.

slices.Concat(orgRoles, []rbac.RoleIdentifier{rbac.ScopedRoleOrgMember(arg.OrganizationID)}, defaultRoles) builds a fresh slice and drops the suppression. Copied from the pre-existing singular sibling, so it naturally resolves when CRF-8's shared helper is extracted.

Done in c61b66d388. The shared helper now builds the role set with slices.Concat(...), which drops the //nolint:gocritic suppression.

P3 [CRF-13] Renaming the deprecated endpoint's operationId from add-organization-member to add-organization-member-deprecated breaks the published API descriptor. (Chopper)

The sibling deprecation on the same file, list-organization-members (members.go:339-341), adds @Deprecated but keeps its operationId unchanged. This PR renames the ID, and swagger.json now emits "operationId": "add-organization-member-deprecated" alongside "deprecated": true.

deprecated: true alone communicates the deprecation; the rename is gratuitous and changes the generated client method name and docs anchor for a released endpoint. Keep the (deprecated) summary suffix but restore @ID add-organization-member and rely on @Deprecated, matching the sibling.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Done in c61b66d388. Restored @ID add-organization-member, so the published operationId and client method name are unchanged; deprecation is now signalled via @Deprecated alone, matching the list-organization-members sibling.

P3 [CRF-12] The @Deprecated use POST .../members instead annotation throws away its migration hint: Swaggo's @Deprecated takes no argument. (Leorio)

swagger.json:4572 is "deprecated": true with no description, and docs/reference/api/members.md only gained the (deprecated) heading suffix. The use POST .../members instead text never reaches the reader.

A developer on the single-member endpoint page sees a deprecated tag and no migration target. This mirrors the pre-existing broken usage at members.go:339, so the convention itself is wrong. Add a @Description line (which Swaggo does emit) pointing to the batch endpoint.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Done in c61b66d388. Moved the migration hint into an @Description line (which Swaggo emits). swagger.json now carries "description": "Deprecated: use POST /organizations/{organization}/members instead." and it renders on the endpoint's docs page.

P3 [CRF-10] The Forbidden branch guarding read permission on each target user is untested. (Bisky)

The handler deliberately calls GetUsersByIDs on the request context, not AsSystemRestricted, so dbauthz enforces ActionRead on each target user; the error maps to httpapi.Forbidden. No test covers a caller who lacks read on a target user.

This is exactly the invariant that would silently break if someone later switched to AsSystemRestricted, and nothing would catch it. Add a case that calls PostOrganizationMembers as a principal without read on the target user id and asserts 403.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

The invariant is preserved (the handler uses the requester context, not AsSystemRestricted), but I did not add a handler test, and here is the reasoning: every privileged caller of this endpoint carries site-wide ResourceUser: {ActionRead} — owner, user-admin, and org-admin (roles.go:581, "To assign organization members, we need to be able to read users at the site wide"). So no standard role can pass the org-member create check while failing the per-user read check; the read-denied 403 is only reachable via a bespoke custom role (an enterprise-gated feature). A test would have to construct that artificial role purely to exercise the branch. I left it out rather than add a contrived fixture, but I'm happy to add a custom-role case in enterprise/coderd if you'd prefer explicit coverage of the regression guard.

P3 [CRF-10] Re-raised by unanimous panel (Netero, Bisky, Hisoka, Mafuuu, Pariston, Razor, Kurapika, Chopper, Meruem). (all P3)

The defense is verified correct: owner/user-admin/org-admin carry site-wide ResourceUser:ActionRead (roles.go:581), so the read-denied 403 is only reachable via a bespoke custom role today. That is a statement about reachability, not about protecting the invariant. GetUsersByIDs under the request context is the only thing stopping a caller with organization_member:create from adding users it cannot read, and members.go already uses AsSystemRestricted in five places, so a future refactor that swaps the request context here would silently drop the gate with nothing red.

This is a security invariant guarded only by prose. Neither the panel nor the author-agent can accept the gap as permanent: please land the custom-role enterprise test you already offered (grant organization_member:create, deny user:read, assert 403) in this PR, file a tracking issue, or have a human explicitly accept the gap. Keeping the thread unresolved until then.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Landed the test in 9f18770002: TestBatchAddMembersReadAuthorization (enterprise). It creates a custom org role with organization_member:{create,read}, assign_org_role:assign, and organization:read but no site-wide user:read (a custom org role can't grant it), assigns it to a caller, and asserts PostOrganizationMembers targeting an unreadable user returns 403. The caller has everything needed to complete the add except read, so if the handler were switched to AsSystemRestricted the call would succeed and this test would go red. That's the regression guard you asked for.

Note [CRF-16] The batch cap 100 has no stated rationale and cannot be shared as a constant. (Gon)

The limit is documented as a range but not why 100. It lives in a struct-tag string literal, so Go cannot reference a named constant there, and the same value bounds the insert transaction size.

Worth a one-line rationale on the field comment (why 100), even though the tag itself must stay a literal.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Done in c61b66d388. Added a rationale to the field comment: the upper bound keeps a single batch insert and its audit fan-out bounded, and callers adding more should page. The tag stays a literal.

Note [CRF-17] ON CONFLICT DO NOTHING omits a conflict target, so it will swallow every future unique/exclusion violation on organization_members, not just the membership PK. (Knuckle)

Today this is exact: the only unique constraint is organization_members_pkey (organization_id, user_id), and this matches the sibling pattern in groupmembers.sql / groups.sql. The loan is latent: the day someone adds a second unique or partial/exclusion constraint, this insert silently drops the offending rows, omits them from RETURNING, and fires no audit, indistinguishable from "already a member."

Naming the target now, ON CONFLICT (organization_id, user_id) DO NOTHING, costs one line and scopes the skip to the conflict you mean. (The sibling queries share this class but are out of scope here.)

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Done in c61b66d388. Named the target: ON CONFLICT (organization_id, user_id) DO NOTHING, so the skip is scoped to the membership PK and a future unique/exclusion constraint won't be silently swallowed. (The sibling group queries share the class but are out of scope here.)

Note [CRF-18] The batch insert's RETURNING * has no ORDER BY, so the handler's response member order is unspecified. (Komugi)

Postgres does not promise RETURNING rows come back in input-array order, so postOrganizationMembers writes members in a data-dependent order. Safe today: TestAddMembers/OK uses require.ElementsMatch and the other cases assert one element.

The moment a future test asserts a multi-member order with require.Equal(members[0]...), it becomes a flake with no code change to blame. Keep the ElementsMatch discipline, or add ORDER BY user_id to pin it.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Kept the ElementsMatch discipline rather than adding ORDER BY. A CTE-wrapped SELECT ... ORDER BY user_id was the only way to attach ordering to RETURNING, and that changed the sqlc-generated return type from []OrganizationMember to a bespoke row struct, cascading through the handler. Instead I documented in the query that the result order is unspecified so callers must not rely on it. c61b66d388.

P3 [CRF-9] The new batch add-members wiring has no frontend test or story coverage. (Bisky)

The page's handler went from N per-user addMemberMutation.mutateAsync calls plus a manual refetch() to a single addMembersMutation.mutateAsync(users.map((user) => user.id)) relying on onSuccess invalidation. OrganizationMembersPage.test.tsx covers only remove-member and update-role; the view story stubs addMembers: () => Promise.resolve(), so the id-mapping and batch mutation are never invoked.

The PR modified the code under test, so the gap is this PR's. Add a play function that clicks add, selects two users, submits, and asserts API.addOrganizationMembers was called once with { user_ids: [id1, id2] } and the list refreshes.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Done in c61b66d388. Added OrganizationMembersPage.stories.tsx with an AddMembers play: opens the dialog, selects two users, submits, and asserts API.addOrganizationMembers was called exactly once with { user_ids: [id1, id2] }, then asserts the newly-added member renders after the list refetches. Page-level so the id-mapping and batch mutation are actually exercised.

P3 [CRF-15] The UI collapses an unbounded selection into one batch call, but the server caps user_ids at 100 and nothing on the client guards it. (Nami)

AddUsersDialog lets selected grow without bound (setSelected([...selected, user]), OrganizationMembersPageView.tsx:121) and sends every id in one request. Select 101+ users, click Add, and the whole batch is rejected 400 with a generic validation error and no hint that the fix is "select fewer than 100."

Atomicity keeps the failure clean (no partial state), so this is a rough edge, not a data hazard: cap selection in the dialog (disable Add past 100, or show a count) so the user does not hit the server wall blind.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Done in c61b66d388. AddUsersDialog now caps selection at 100 (MAX_MEMBERS_PER_ADD): checking past the cap is a no-op, a "{n} of 100 selected" counter is shown, and a warning line appears once the cap is hit, so users don't submit blind into the server's 400.

P3 [CRF-23] The MAX_MEMBERS_PER_ADD cap guard added to fix CRF-15 shipped with no test coverage. (Bisky)

The AddMembers story selects exactly two users and never approaches the cap, and grep finds no test referencing MAX_MEMBERS_PER_ADD or the warning string. The guard that prevents the blind 400 is itself unguarded, so a regression silently reintroduces the exact bug CRF-15 fixed.

Sketch: a story whose getUsers mock returns 101 users, select 100, assert the button is disabled and the warning renders, then assert the 101st onChange is ignored (selected stays at 100).

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Done in 9f18770002. Added an AddUsersSelectionCap view-level story: getUsers returns 101 users, the play selects exactly 100, asserts the 100 of 100 selected counter and the cap warning render, that the submit stays enabled at the cap, and that clicking the 101st checkbox is ignored (stays unchecked, counter stays at 100).

P3 [CRF-25] The plural branch of manualMembershipBlockedResponse is never exercised by any test. (Chopper)

The only test that reaches this through the batch handler (enterprise/coderd/userauth_test.go) passes a single user ID, so it hits the singular branch. The len(usernames) > 1 branch that builds "Users X, Y are OIDC users" via strings.Join has zero coverage.

This is exactly the signal an admin sees when they batch-add several OIDC-synced users, which is the whole reason the batch endpoint exists. CRF-5 covered the singular path; the plural branch it introduced is the gap. One enterprise case submitting two OIDC users and asserting the plural message closes it.

🤖

🤖 Comment by Coder Agents on behalf of Jake Howell

Done in 9f18770002. Added TestManualMembershipBlockedResponse (internal coderd test) covering both branches, asserting the plural wording Users alice, bob are OIDC users / not allowed for these users that a batch of multiple OIDC-synced users produces. I used a direct unit test of the message builder rather than a second enterprise org-sync login because it deterministically pins the plural copy without the brittleness of driving two OIDC sign-ins; happy to add the full integration case too if you'd rather have it end-to-end.

Nit [CRF-24] allMembers holds only the newly-inserted members, not all requested members. (Gon)

InsertOrganizationMembersBatch runs ON CONFLICT DO NOTHING ... RETURNING *, so it returns only rows actually inserted (the SQL and SDK docs both confirm the subset semantics). The name claims the opposite, and it flows into the audit loop and convertOrganizationMembers.

Code is correct, but a maintainer extending this handler could reasonably assume the response and audit cover every requested user. Rename to newMembers or insertedMembers.
