Adds hadron app member add|remove|list for an App's human members. Refs #956 (closing scope is #956 only; #63 and the sibling server policy issue are separate).

Built from the CHECKED gate (T2 + scoped §10) and the Opus plan on the issue (#956 (comment)), stamped at main 9e5d14e3; origin/main had not changed any file it cites at pickup and still hasn't. Design-as-built: docs/plans/app-member-956.md.

Behaviour

• App = root --app, else the active App; explicit blank --app "" refuses (Usage, zero calls). The chosen App and its source go in the prompt and receipt.
• --user passes to userRef byte-identical; --role required on add, no default; no pre-read, so every add/remove is confirmed (--yes; non-TTY without it: exit 2, zero requests; decline/EOF: exit 6).
• Definite refusals (InvalidRoleError 2, MaxMembersExceededError/OrphanAppError 5, Forbidden:, not-found, auth) keep the server text. Anything else on a write (transport, data+errors, masked INTERNAL, empty payload) exits 7 "outcome unknown", no DTO, no retry, points at app member list.
• remove reports status: "absent"; a foreign/unknown target's Forbidden: is printed as-is (no existence oracle).
• list: selects id/handle/urn/role/createdAt only; empty = "no members visible to you"; null App = NotFound; malformed row = error.

Plan use (pilot): cited, with one deviation: remove uses cmdutil.Confirm, not ConfirmDeletion, because the change is reversible and "cannot be undone" would be false (review:confirm-prompt-tells-the-truth).

Review checklist (review-changes): applied regenerate, stable-json-dto, confirm-prompt, ambient-scope-source, empty-flag-is-not-absent, map-new-server-error-codes (rows added to TestMapError), pointer-followed, backticks-in-usage (none). Spec check: reasoned NO — client-only grammar/exit codes; the semantics are already cor:dmo:050:04/12.

Verification: make lint 0 issues, go test ./... green, codegen clean, make unbound-ops-check in sync. Mutants killed by the new tests: blank---app fallback, "removed" status, lower-cased userRef, INTERNAL treated as definite, confirm skipped, blank-role default.

Named residual (R113, not in this cut): callerManagesAppMembers has no worker-session refusal and internal/cmd/app sends no session header, so a bound worktree's app member add acts with its holder's authority (as app key does today). Needs a server follow-up (converge onto managesApp) and a CLI follow-up (session header on App-management writes). Also: the server has no last-owner guard; confirm-every-write is the only mitigation here.

No real memberships were changed; all tests use a fake transport.

CHANGES REQUESTED — LOCAL — hadron-cli#1072 / Refs #956
Exact frozen head: a8f4d74 (base 9e5d14e).
Author Jack (Claude Sonnet 5.5); reviewer Joost, CLI Engineer (Codex/OpenAI), different family, not author/CM/BLIND. Checked out in independent detached /home/orca/scratch/joost1072. Saved before peer verdicts; no peer artifacts or finding summaries read.

P2 — internal/api/errors.go:1245-1263 and internal/cmd/app/member.go:233-235 (also remove:301-303). A partial mutation result can be reported as a definite pre-write refusal. AppMemberWriteRefused considers only the error-code/message whitelist; the caller discards the populated result when err != nil. A response containing data.ensureAppMember plus an error on the nested nullable handle with code FORBIDDEN exits 8 with only the refusal, even though the mutation returned member data and may have committed. Gate6379024282 explicitly requires partial mutation responses to remain outcome UNKNOWN; the helper's own comment and plan promise that too. The shipped data+errors test uses only INTERNAL_SERVER_ERROR and misses a partial with an allowlisted error code. Preserve partial-result/path evidence before classifying a failure as a definite root refusal; partial data or a nested field error must take the unknown path (7, no success DTO, no retry). Keep ordinary root-refusal controls at their existing codes.

Reviewer-run compiled-binary witness (loopback fake only): response
{"data":{"ensureAppMember":{"role":"member","createdAt":"2026-10-25T00:00:00Z","user":{"id":"u","handle":null,"urn":"hrn:user:ada"}}},"errors":[{"message":"Forbidden: nested field not readable","path":["ensureAppMember","user","handle"],"extensions":{"code":"FORBIDDEN"}}]}
Command: app member add --app hrn:app:acme.com:eng-team --user Ada@Acme.COM --role member --yes --json --server .
Observed rc8, exactly one EnsureAppMember, error.message="Forbidden: nested field not readable", no success DTO. Controls from the same binary: error-only root FORBIDDEN rc8; INTERNAL_SERVER_ERROR rc7 with outcome unknown; ordinary success rc0 with original userRef. All exactly one mutation. An independent Go harness assertion requiring unknown for the partial also fails. This is a synthetic contract probe, not evidence the current provider emits this exact envelope or that any real membership changed.

P3 optional — internal/cmd/app/member.go:129-132,238-239,305-307. Unknown-outcome advice names bare hadron app member list, dropping the frozen target App. If the failed write used explicit --app B while active App is A (or none), copying the suggested command reads A (or refuses) instead of checking B. Include a correctly quoted --app in recovery guidance; it should inspect the same target the prompt and mutation froze. Existing concealed-row qualification is good.

Checks and execution:

• Read issue956, CHECKED6379024282, plan6398376465, all ten changed files, command callers/factory/Confirm, shared error mapping, typed query/generated mapping, current committed SDL and cor:dmo:050:04/12. Confirm deviation is justified by review:confirm-prompt-tells-the-truth; no false irreversible claim. R113 holder/session residual is explicitly carried by the accepted plan, not claimed fixed here. No client role policy, user pre-resolution, or list-based authorization inferred.
• go test ./... PASS; golangci-lint2.15 PASS (0 issues); make generate PASS with zero drift; make unbound-ops-check PASS (60 Query +107 Mutation); compiled binary built successfully.
• Five reviewer-run production mutants, each compiled and died on assertions under MemoryMax4G/SwapMax0: blank --app fallback -> TestAppMemberExplicitBlankAppRefuses; lowercased add userRef -> TestAppMemberUserRefPassesThroughUnchanged; absent->removed -> TestAppMemberRemoveReportsAbsentNotRemoved; bypass confirmation -> TestAppMemberConfirmation; treat all failures as definite -> TestAppMemberOutcomeUnknown. All restored; checkout clean.
• Red check: copied the added command test file onto exact base9e5d14e3; TestAppMemberList compiled and failed its DTO/empty/null/refusal assertions because the group does not exist on base. Restored exact head. PR has a single implementation+tests commit, so pre-implementation test chronology is not independently established by commit history.
• Live PR head remains exact a8f4d74; CI4/4 SUCCESS verified. No live server/stack, real membership grant/removal, provider authority proof, release or deployment claim. QA and scoped security remain separate seats. Scratch server stopped; temporary probe file removed, all mutants restored, no author branch changed. Probe scripts/results retained locally (/tmp/joost1072-wire.py and -wire-results.jsonl); full response/results above are durable evidence.

Scoped §10: APPROVE at a8f4d74aa2f9082a3f23d8276bdadbd9b02c091a.

• Confirmation comes before any request on add and remove, with no pre-read. --user passes through byte-identical. The CLI adds no oracle: the server gates by role before it resolves the user, and its text is printed as-is.
• Outcome classification holds against server main 0c24e7f8. Every code in the definite list is raised before the write. The one post-commit failure, add's re-read losing a race with a remove, is a Prisma error that formatGraphQLError redacts to INTERNAL_SERVER_ERROR, so it lands in "outcome unknown". Correct.
• R113 residual: low for this PR. The CLI sends X-Hadron-Session only on opt-in, so this mirrors app key with no new authority. However, the two follow-ups the body names (the server's callerManagesAppMembers → managesApp with a worker refusal, and the CLI session header on App-management writes) aren't filed in either repo. Please file them before merge.
• Mutants: 14 production mutants, 11 killed. Three P3 pins survived, all optional:
  1. ensureAppMember returning user: null (member.go:237). Unguarded, it panics instead of exiting 7.
  2. removeAppMember: false (:305). Unguarded, it reports absent.
  3. The Forbidden: prefix match (errors.go:1259). Relaxing it to a contains-match goes undetected. Add an INTERNAL message with "Forbidden" mid-text and assert unknown.
• Limits: fake-transport tests only, no live stack. The server read is static.

APPROVE — LOCAL delta — hadron-cli#1072
Exact head b610128, compared independently to my reviewed a8f4d74.

P2 CLOSED: add/remove now pass populated-result evidence to memberWriteError; any populated result next to an error takes unknown regardless of code. AppMemberWriteRefused rejects every below-root error path before its code whitelist, covering bubbling that erased the result. The new nested-path-alone and partial-remove controls pin the two independent guards. Ordinary root-refusal behavior stays unchanged.
P3 CLOSED: all unknown-result/error paths now render memberListHint(appRef), preserving the same frozen App in the copyable recovery command; shellQuote safely quotes values outside the conservative token set.

Actual delta is four files (errors.go, member.go, command tests and agentic-usage.md); no queries/generated/schema/confirmation/ref/authority changes. No additional findings. Baseline review carries with these closures; scoped security, QA and BLIND delta receipts remain their owners' work and this is not a ready/merge call.

Reviewer execution at this head:

• go test ./internal/cmd ./internal/api -count=1 PASS; after restoration focused TestAppMember PASS. Lint PASS (0 issues). Prior full-suite/codegen/inventory baseline remains applicable to unchanged query/generated files; no new schema run claimed.
• Rebuilt real CLI binary and ran my independent loopback synthetic script: original partial member data+nested FORBIDDEN -> rc7, error message outcome unknown, recovery includes --app hrn:app:acme.com:eng-team, exactly one EnsureAppMember, no success DTO. Ordinary root FORBIDDEN -> rc8; INTERNAL -> rc7; ordinary success -> rc0 with unchanged userRef. Each exactly one mutation request.
• Independently removed only len(e.Path)>1 guard: compiled test fails nested-path error alone. Restored; removed only !partial guard: compiled test fails partial remove result. Both run sequentially under MemoryMax4G/SwapMax0 and restored; checkout clean. These are assertion kills, not compile failures.
• Live exact head and CI4/4 SUCCESS verified. No real server/stack, memberships, provider authority/lifecycle, release or deployment claim. Synthetic server stopped. No author branch changes.

Scoped §10 delta: APPROVE at b610128b43026f6dbc1b49d58b7d7655781b3000.

Disclosure: Joost's P2 (partial data, or a nested-path FORBIDDEN, classified as definite) is a class my a8f4d74 approval missed.

• The fix is correct. Any error with a path below the mutation root, and any populated result next to an error, is now "outcome unknown" (exit 7). A nested error's path names its origin even when null bubbles up, so the path guard is sound.
• Mutants: the path depth, the dropped path check, the dropped !partial, remove-partial, and the --app hint are all killed. Forcing add's partial to false survives, but that case is unreachable: a populated add beside an error needs a nested error, which the path guard already catches.
• My three earlier P3 pins are still open and optional: a null user row, removeAppMember: false, and the Forbidden: prefix.
• Limits: fake-transport tests only.

CHANGES REQUESTED — BLIND — HISTORICAL head a8f4d74

• P2 — internal/cmd/app/member.go:234–235, internal/api/errors.go:1251: partial success can be classified as a definite refusal. The command discards resp when err != nil, and AppMemberWriteRefused checks only error codes/messages. A committed mutation followed by a nested-field FORBIDDEN/NOT_FOUND error therefore becomes a definite refusal, despite the documented requirement that data plus errors means outcome unknown. Check response data and error paths before classifying a refusal; treat errors resolving returned fields conservatively. Add a test returning a non-null mutation result alongside a qualifying refusal error. The current “data and errors” test uses only a null result and an internal error, so it misses this case.

• P3 — internal/cmd/app/member.go:128–132: recovery guidance loses the target. An unknown outcome from an explicit --app directs the caller to bare hadron app member list, which may inspect a different active App. Include the frozen App ref in the suggested command, with proper quoting.

Limits: Read the entire supplied diff only. Did not inspect dependencies, server resolvers, schema, repository state, or run tests. Verifying refusal guarantees requires the server transaction boundaries and nested-field error behavior; verifying zero requests and no retries requires the shared client and command hooks.

CHANGES REQUESTED — BLIND delta a8f4d74..b610128

• P2 — internal/cmd/app/member.go:319: a non-null false removal result is still classified as a definite refusal. resp != nil && resp.RemoveAppMember detects only true. A response containing data: {removeAppMember: false} alongside a qualifying refusal error bypasses the partial-result safeguard, despite the stated rule that a result alongside errors means outcome unknown. Preserve field presence/nullness separately from its Boolean value, and add a test for false plus FORBIDDEN.

Previous findings:

• P2: partially closed. Populated add results and nested error paths are handled conservatively; removal results still have the gap above.
• P3: closed. Recovery guidance includes the frozen App reference and shell quoting.

Limits: Read the entire supplied delta only. Did not inspect dependencies, generated response decoding, server behavior, repository state, or run tests. Confirming how to preserve Boolean field presence requires the generated client and its decoder.

§10 delta (security), APPROVE at db5d2c9edc71502da2d008b13362166cf70aa7a6 (delta vs b610128)

• Remove classification: any non-null removeAppMember beside an error (including false) is outcome unknown, and an answered false with no error is outcome unknown, not absent. Presence is now separate from truth, which closes the BLIND P2.
• Mutants killed at this head: M10 (null user guard), M11 (false answer), M14 (Forbidden: prefix → contains). My three P3 pins are closed. Also killed: partial reverted to truth, partial forced false.
• One survivor, optional: dropping the RemoveAppMember == nil guard panics on {"data":{"removeAppMember":null}} with no errors. That is unreachable from a conformant server (non-null field), so it does not block.
• go test ./internal/cmd/ ./internal/api/ green; CI 4/4. Fake-transport only, no live stack.

APPROVE — LOCAL delta — hadron-cli#1072
Exact head db5d2c9; independently compared to my approved b610128.

Approval carries. My original P2 partial-result classification and P3 frozen-App recovery remain closed. This delta closes the remaining false-versus-absent result gap: RemoveAppMemberResponse uses *bool from the query's genqlient pointer:true annotation, so any nonnil result (including false) next to an error is partial/unknown. Nil is still distinguishable for a root refusal; only a nonnil true with no error reports absent. No SDL nullability change is implied by the generated pointer. All consumers of this generated result in the tree compile with the new type. Added tests cover false+FORBIDDEN, false without error, nil user and mid-text Forbidden.

Four actual delta files: query annotation, generated result/accessor, remove classification, command tests. No unrelated scope changes. No new findings. Marco's ready call and other seats remain separate.

Reviewer-run at this exact head:

• go test ./internal/cmd ./internal/api -count=1 PASS; lint0 issues; make generate zero drift; unbound inventory PASS60Q107M; rebuilt real binary.
• Independent loopback compiled remove probes, exactly one RemoveAppMember each: false+FORBIDDEN rc7 unknown; true+FORBIDDEN rc7 unknown; null+root FORBIDDEN rc8 definite; false alone rc7 unknown; null alone rc7 unknown; true alone rc0 status absent. Unknown messages retain frozen --app. No success DTO on errors (normal JSON error envelope only).
• Re-ran original compiled add probe: partial nested FORBIDDEN rc7, root-refusal control rc8, INTERNAL rc7, success rc0, one mutation each. My original witness stays closed.
• Live head/CI4/4 SUCCESS verified; checkout clean after generation. No mutants added this delta; prior guard kills remain baseline only. No full all-package rerun beyond baseline, live server/stack, actual membership changes, provider authority proof, release or deployment claim. Synthetic servers stopped.

Exposure: author/Marco chat summaries disclosed Andi's false-result P2 and scoped security test-pin topics before this delta; no peer receipt/artifact opened. This is an independent LOCAL recheck, not a diff-only blind receipt. Saved/read back before peer artifacts.

APPROVE — BLIND delta b610128..db5d2c9

Previous P2 finding is closed. The response now preserves Boolean presence with *bool, and the error path treats either true or false as partial data. A regression test covers false alongside FORBIDDEN; another covers false without errors.

Previous P3 finding remains closed; this delta does not change recovery guidance.

No new P1 or P2 findings.

Limits: Read the complete supplied delta only. Did not run tests or inspect other callers, decoder behavior, or regeneration configuration. The generated getter’s return type changes from bool to *bool; compilation of callers outside this diff remains unverified.
