Add two new pipelines: + - `POST /api/v1/admin/bootstrap-login` — calls `step.auth_admin_bootstrap_code_verify`, on success creates session, redirects to passkey-enrollment UI. + - Admin UI affordance for "enroll passkey for my account" already exists (passkey routes work); just gate it on session role check. +5. Add `super_admins: [{email: "codingsloth@pm.me", default_role: "super_admin"}]` to BMW's `auth.credential` module config. +6.

Separate PR against workflow-compute. + +## Assumptions (load-bearing) + +1. workflow-plugin-auth v0.3.0 can ship without coupling to a new workflow engine version — current v0.51.6 pin is sufficient. *If false:* engine bump cascades. +2. Strict-proto contract additions are non-breaking for existing consumers (additive only, no signature changes to existing steps). *If false:* major bump + cascade through every consumer. +3. BMW currently passes wfctl validation against app.yaml after the 5 hotfix guards land. *If false:* the hotfix PR must include any related fixes surfaced by validation. +4. The pre-existing `.worktrees/bmw-prod-auth-passkey/` worktree contains compatible work that doesn't conflict with our changes. *If false:* operator resolves before Phase 3 lands. +5. `auth.credential` module currently has a database backend (SQLite or PostgreSQL via workflow-plugin-pgchannel) suitable for adding the new `auth_admin_bootstrap_codes` table. *If false:* schema location decision needed. +6. Single super-admin (codingsloth@pm.me) is acceptable for BMW initial bootstrap; multi-tenant super-admin config can stay as a list for forward compatibility but only one entry initially. *If false:* nothing — list shape already accommodates. +7. workflow-compute's existing `dashboard login-codes` flow is NOT in this PR's path; only Phase II migrates it. *If false:* scope creeps significantly; refuse and split. +8. Operator security model: bootstrap codes are delivered via secure channel (1Password, Signal, etc.) — the plugin is not responsible for delivery. *If false:* must add SMS/email magic-link delivery path, which is partially in plugin already but not wired to bootstrap. + +## Rollback (per change class) + +| Phase | Change class | Rollback | +|---|---|---| +| 1 | BMW YAML (no engine/migration/version-pin changes) | Revert PR; signup/login returns to broken-500 state (no worse than baseline). | +| 2 | workflow-plugin-auth v0.3.0 release (proto contract additions, schema migration, binary) | Untag v0.3.0; consumers stay on v0.2.4. New migration `auth_admin_bootstrap_codes` is additive — leaving the empty table behind is safe; drop separately if cleanup desired. | +| 3 | BMW migration onto plugin steps | Revert PR; BMW reverts to bespoke step.bmw.* steps. Bespoke step files preserved in same commit's separate cleanup commit so revert needs no recovery. Bootstrap codes table left in place (harmless empty table). | + +## Verification gates + +- **Phase 1:** Local `docker compose up` + manual curl of all 5 scenarios; user-visible signup/login working in browser.

Operator delivers code out-of-band to user. +**New gRPC admin RPC:** `AdminBootstrapLink(email) → magic_link_url` — convenience wrapper that the plugin exposes for `wfctl` to call. Internally: looks up super_admins, runs `step.auth_magic_link_generate` logic, returns URL string. The caller (BMW) is still responsible for storing the token_hash via its pipeline; the RPC just mints and the host echoes the URL. *Decision:* implemented as a new gRPC service method on the existing plugin server interface (avoids adding wfctl knowledge of per-plugin CLI). -Migration adds `auth_admin_bootstrap_codes` table; ships as standard plugin migration (already-existing migration pattern, see `internal/module_credential.go` schema setup). +Wait — that requires BMW to also store the hash, which means the RPC alone doesn't work. **Revision:** the RPC pattern is wrong; the simpler pattern is: -Proto contract additions: `BootstrapCodeGenerateInput/Output`, `BootstrapCodeVerifyInput/Output`, `BootstrapSuperAdminConfig`, `BootstrapVerifyError`.

BMW currently passes wfctl validation against app.yaml after the 5 hotfix guards land. *If false:* the hotfix PR must include any related fixes surfaced by validation. -4. The pre-existing `.worktrees/bmw-prod-auth-passkey/` worktree contains compatible work that doesn't conflict with our changes. *If false:* operator resolves before Phase 3 lands. -5. `auth.credential` module currently has a database backend (SQLite or PostgreSQL via workflow-plugin-pgchannel) suitable for adding the new `auth_admin_bootstrap_codes` table. *If false:* schema location decision needed. -6.

Operator security model: bootstrap codes are delivered via secure channel (1Password, Signal, etc.) — the plugin is not responsible for delivery. *If false:* must add SMS/email magic-link delivery path, which is partially in plugin already but not wired to bootstrap. +1. **(Verified rev-2)** workflow-plugin-auth v0.2.4 gRPC contract surface is compatible with BMW's currently-pinned workflow engine (Phase 0 confirms this; otherwise bump plugin's engine pin first as PR-2a). +2. Strict-proto contract additions in Phase 2 are non-breaking — only adds new step + new optional proto field. No signature change to existing 25 steps. +3. BMW's existing CSRF middleware (if present) covers POST `/admin/bootstrap-link`. **If absent in BMW:** add a CSRF middleware to the admin pipeline group as a separate sub-task in PR-3. +4. BMW's ingress / reverse proxy can constrain `/admin/bootstrap-link` to localhost-bind. **If false:** rely on `X-Admin-Bootstrap-Token` header alone (declarative env var) plus rate-limit; document operator security model in BMW runbook. +5. BMW's existing magic-link table schema exists or can be added in one migration alongside the bootstrap pipeline. +6. Single super-admin email (`codingsloth@pm.me`) is acceptable for initial production; the proto list shape accommodates multiple. +7. Operator delivers magic-link URL via secure channel (1Password, Signal, in-person paste). Plugin not responsible for delivery. +8. workflow-compute's dashboard login codes stay untouched in this design. **If false:** scope creeps significantly; refuse and split. ## Rollback (per change class) | Phase | Change class | Rollback | |---|---|---| -| 1 | BMW YAML (no engine/migration/version-pin changes) | Revert PR; signup/login returns to broken-500 state (no worse than baseline). | -| 2 | workflow-plugin-auth v0.3.0 release (proto contract additions, schema migration, binary) | Untag v0.3.0; consumers stay on v0.2.4.

Key change in rev 3: dropped all plugin work (no new step types, no proto changes, no v0.3.0 tag). All work is BMW-side. Plugin "reusable extraction" deferred to Phase II when a second consumer materialises (YAGNI). Critical findings from cycle 2 resolved: (a) promoted BMW engine pin bump from v0.20.1 to a first-class PR-0 (likely proximate cause of current 500s — gRPC strict-contract handshake fails against old engine), (b) reuse existing `magic_link_tokens` table (not invent `auth_magic_links`), (c) acknowledged bespoke `step.bmw.generate_token` survives this design. ## Goal -1. Restore BuyMyWishlist (BMW) **signup AND login** (both currently HTTP 500) via an exhaustive nil-deref audit of all auth pipelines. -2. Add a **reusable admin bootstrap** capability to `workflow-plugin-auth`: declarative super-admin email allowlist + a single new step (`step.auth_super_admin_allowlist`) that composes with the existing `step.auth_magic_link_generate`/`step.auth_magic_link_verify` steps. Operator runs `wfctl plugin auth admin-bootstrap-link --email ` against the host, host hits a localhost-bound BMW admin endpoint, BMW pipeline checks allowlist and mints a magic link returning the URL on stdout. User pastes URL → session → enrols passkey via existing passkey routes → bootstrap retired. -3. Migrate BMW's two password-related bespoke steps onto plugin-provided equivalents (`step.bmw.hash_password` → `step.auth_password_hash`; `step.bmw.verify_password` → `step.auth_password_verify`). Defer `step.bmw.generate_token` replacement to Phase II SSO IDP (no plugin equivalent yet; 9 call sites verified). -4. Document a forward path for cross-product SSO (issuer, JWKS endpoint, refresh tokens) as Phase II; **not built in this design**. +1. Restore BuyMyWishlist (BMW) **signup AND login** (both currently HTTP 500). Root cause is suspected to be plugin-engine handshake failure (BMW pins workflow v0.20.1; existing in-use auth-plugin pipelines target v0.51.6-era strict-proto contracts), with template nil-derefs as secondary fragility surface. Both addressed. +2. Stand up an **admin bootstrap login flow** for BMW operator (`codingsloth@pm.me`): operator triggers magic-link mint via a localhost-bound BMW endpoint → URL → user redeems → JWT session → enrols passkey via existing passkey routes → subsequent logins use passkey; bootstrap is break-glass only. +3. Migrate BMW's two trivial password steps onto plugin equivalents (`step.bmw.hash_password` → `step.auth_password_hash`, `step.bmw.verify_password` → `step.auth_password_verify`). Bespoke `step.bmw.generate_token` retained (10 existing + 1 new call site in bootstrap-redeem = 11 total; no plugin replacement exists today). +4. Document a forward path for cross-product SSO (issuer, JWKS endpoint, refresh tokens, JWT issue/verify) and plugin extraction of the bootstrap pattern as **Phase II**, triggered when a second consumer materialises (workflow-compute migrating its dashboard login codes is the most likely trigger). **Not built in this design.** -## Out of scope (deferred) +## Out of scope (deferred to Phase II or further) -- **Cross-product SSO IDP surface** — Phase II separate design doc. workflow-compute feature-state.md §"Cross-product passwordless identity" tracks this as T411-T413. -- **`step.bmw.generate_token` retirement** — Phase II only. 9 call sites in `app.yaml` (`:668, :1103, :6848, :7023, :7241, :7571, :7625, :7887, :10940`). No plugin equivalent exists (no `auth_jwt_*` step in v0.2.4). Removing bespoke `bmwplugin/step_auth.go` waits for that. -- **SSH-key signature binding on bootstrap link** — user's mental model mentioned SSH keys; workflow-compute's own pattern doesn't actually use SSH keys (its `wc_`-prefix codes are random tokens delivered out-of-band). Same pattern adopted. If SSH proof-of-possession is later wanted as defence-in-depth, it's a Phase II add (`ssh_signature` optional field validated against pubkey in config). -- **Replacing workflow-compute's existing dashboard login-codes flow** — Phase III follow-up; workflow-compute keeps its bespoke path until separate migration. +- **Plugin changes.** No new step types, no proto changes, no module-config additions, no v0.3.0 tag of `workflow-plugin-auth`. The existing v0.2.4 surface is sufficient (passkey + magic-link + password steps all already present). Plugin extraction of the bootstrap-pipeline pattern is deferred until a second consumer needs it. +- **Cross-product SSO IDP surface** — `auth_jwt_issue` / `auth_jwt_verify` / `auth_jwks_serve` / refresh tokens. Separate Phase II design. workflow-compute feature-state.md §"Cross-product passwordless identity" tracks this as T411-T413. +- **`step.bmw.generate_token` retirement.** Cannot retire until Phase II SSO IDP ships an `auth_jwt_issue` step. Retained as-is. 10 existing call sites + 1 new (bootstrap-redeem) = 11 total. +- **SSH-key signature binding on bootstrap link.** User mentioned SSH-keys, but workflow-compute's actual pattern doesn't use them — codes are random tokens delivered out-of-band. Same pattern adopted. Future Phase II add if proof-of-possession proves valuable. +- **Replacing workflow-compute's existing dashboard login-codes flow.** Phase III follow-up; workflow-compute keeps bespoke path. -## Top doubts (resolved from rev-1 adversarial findings) +## Top doubts (resolved from cycle-1 + cycle-2 adversarial findings) -| Doubt (rev 1) | Resolution (rev 2) | +| Doubt (origin) | Resolution (rev 3) | |---|---| -| "Migration runner pattern" not in plugin | Plugin has **no migrations directory** (verified). Magic-link step is stateless-with-caller-checkpoint — caller (BMW) stores token_hash in its own DB. No plugin migration needed. | -| CLI in gRPC plugin binary | Not a CLI in the plugin binary. Plugin exposes step + new gRPC admin RPC (`AdminBootstrapLink`) which `wfctl` calls. Plugin runs inside engine, has DB connection + config naturally. | -| HKDF master key source | None — reusing `step.auth_magic_link_*` which already takes `signing_secret` (BMW's `jwt_secret`). Rotation invalidates outstanding links (acceptable). | -| Phase 1 only fixes login, user said signup too | Phase 1 now requires an **exhaustive grep** of `.row.` accesses + dry-run of register + login + passkey pipelines. Not the 5-site sample. | -| `step.bmw.generate_token` has no plugin equivalent | Acknowledged. Replacement deferred to Phase II. Phase 3 only retires hash/verify_password. Bespoke `step_auth.go` survives Phase 3 (delete in Phase II). | -| Engine pin v0.51.6 stale vs v0.57.1 | Phase 0 = verify plugin v0.2.4 loads in BMW's current engine pin. If incompatible, bump engine pin + rebuild plugin first (separate PR). Memory shows the sentinel-removal cascade hit 4 plugins to v2.0.0 on 2026-05-17 — auth was NOT in that cascade so v0.2.4 contract surface should still be compatible, but it must be verified in Phase 0. | -| Worktree `.worktrees/bmw-prod-auth-passkey/` not found | Assumption removed. Phase 3 implementer will check for in-flight passkey work via `git worktree list` and resolve conflict if found. | -| `super_admins` lookup keyed by email vs user_id | Lookup is by email at code-mint time. Pipeline auto-creates the user row with `role='super_admin'` on first redeem if not yet present. Subsequent redeems update existing row. | -| Admin role propagation unspecified | Bootstrap-login pipeline writes `role='super_admin'` into the `users` table on first redeem (UPSERT) and the existing session-creation step picks up that role into the JWT claim. No new role-propagation primitive. | -| New module type vs extend `auth.credential` | **Extend `auth.credential`** with `super_admins: [{email, default_role}]` config field (adds one field to `CredentialModuleConfig` proto). No new module type. | -| CSRF / rate-limit on `/admin/bootstrap-login` | Re-uses BMW's existing CSRF middleware on POST routes. Rate-limit at ingress (BMW already has standard `/api/v1/auth/*` rate-limit). Documented but no new code. Endpoint is localhost-bound for the mint side; redeem side is the standard magic-link-verify pattern (single-use, time-limited). | - -## Phases - -### Phase 0 — Engine compatibility verification (zero-LOC, just a check) - -Before any code change in plugin or BMW: -1. Confirm BMW's actual workflow engine pin (`grep "workflow " buymywishlist/go.mod`). -2. Confirm whether sentinel-removal (workflow v0.57.x, 2026-05-17 cascade) affects plugin-auth gRPC contract surface. workflow-plugin-auth v0.2.4 uses strict-proto contracts (`internal/contracts/auth.proto`, `authContractRegistry` in `internal/plugin.go:265-300`) — these should survive the cascade unchanged, but verify by loading the plugin in the BMW-pinned engine and running an existing pipeline. -3. If incompatible: bump `workflow` pin in plugin go.mod, rebuild, retag (e.g. v0.2.5). Separate PR before Phase 2. - -**Output:** a single answer in PR-2's description — "Phase 0 verified at workflow vX.Y.Z" or "Phase 0 surfaced engine-pin bump required, shipped as PR-2a". - -### Phase 1 — BMW signup/login hotfix (independent, ship first) - -Exhaustive audit: - -1. `grep -n "\.row\." app.yaml` (current count: 20 across full file).

If signup additionally fails for a non-nil-deref reason (e.g. `step.auth_methods_policy` config issue, password_enabled returning nil, hash_password failing because `auth.credential` module isn't loaded), root-cause and fix inline. -5. Reverse-curl: confirm `wfctl validate app.yaml` is green and `docker compose up` runs to ready state. - -**Ships as PR-1 against `buymywishlist`.** Restores access independently of plugin work. - -### Phase 2 — workflow-plugin-auth admin bootstrap (small, additive) - -**Single new step type:** `step.auth_super_admin_allowlist` - -- Input: `{email}` (current step input). -- Config: `super_admins: [string]` (list of emails) — sourced from `auth.credential` module config via the existing config-flow. -- Output: `{is_admin: bool, default_role: string}` — strict-proto contract additions in `internal/contracts/auth.proto`, registry entry in `internal/plugin.go:authContractRegistry`, typed wrapper in `internal/typed.go`, implementation in new file `internal/step_super_admin_allowlist.go` (~80 LOC). - -**Module config extension:** add `super_admins: [{email: string, default_role: string}]` field to `CredentialModuleConfig` proto. Default empty (back-compat). Migration cost: regen proto + add 1 field to `module_credential.go` config-load path. - -**New gRPC admin RPC:** `AdminBootstrapLink(email) → magic_link_url` — convenience wrapper that the plugin exposes for `wfctl` to call. Internally: looks up super_admins, runs `step.auth_magic_link_generate` logic, returns URL string. The caller (BMW) is still responsible for storing the token_hash via its pipeline; the RPC just mints and the host echoes the URL. *Decision:* implemented as a new gRPC service method on the existing plugin server interface (avoids adding wfctl knowledge of per-plugin CLI). - -Wait — that requires BMW to also store the hash, which means the RPC alone doesn't work. **Revision:** the RPC pattern is wrong; the simpler pattern is: - -**Operator workflow (revised):** -1. Operator hits BMW's `POST /admin/bootstrap-link` endpoint over `localhost` only (BMW gates by listener IP) with header `X-Admin-Bootstrap-Token: $BOOTSTRAP_OPERATOR_TOKEN` (env-var in BMW config). -2. BMW pipeline: - - Parse body for `email`. - - Call `step.auth_super_admin_allowlist` to verify email is in allowlist. - - On allowlist match: call `step.auth_magic_link_generate` (existing step) with `email` + `signing_secret={{ config "jwt_secret" }}`. - - Insert `(token_hash, email, expires_at, purpose='admin_bootstrap')` into BMW `auth_magic_links` table (BMW-side; not plugin-side). - - Return JSON `{magic_link_url: "https:///admin/bootstrap-redeem?token="}` to operator stdout. -3. Operator pastes URL into browser. -4. BMW `GET /admin/bootstrap-redeem?token=…` pipeline: - - Look up `auth_magic_links` row by token hash. - - Call `step.auth_magic_link_verify` to validate. - - UPSERT into `users` table with `role='super_admin'` on first redeem. - - Run existing session-creation step (issues JWT with `role` claim). - - Redirect to `/admin/enrol-passkey` (existing passkey route, gated to authenticated session). -5. User enrols passkey via existing passkey routes. -6. Future logins use passkey; bootstrap retired except as break-glass. - -**Net plugin additions:** -- 1 new step type (`step.auth_super_admin_allowlist`) -- 1 proto config field (`super_admins` in `CredentialModuleConfig`) -- No new module type, no new migrations, no new tables, no new CLI, no new gRPC RPC - -**Plugin LOC estimate:** ~120 LOC + 4 proto messages + ~30 LOC test. - -Tag as **v0.3.0** (minor: additive feature, no contract breakage on existing surface). - -### Phase 3 — BMW migration - -1. Replace `step.bmw.hash_password` → `step.auth_password_hash` (1 call site). -2. Replace `step.bmw.verify_password` → `step.auth_password_verify` (1 call site; line 1073). -3. **KEEP** `step.bmw.generate_token` (9 call sites). Retirement deferred to Phase II. -4. Add `auth.credential` module config: `super_admins: [{email: "codingsloth@pm.me", default_role: "super_admin"}]`. -5. Add BMW migration: `CREATE TABLE auth_magic_links (token_hash, email, expires_at, purpose, consumed_at)` if it doesn't already exist (check current schema; BMW already has email-magic-link infrastructure per investigator findings). -6. Add `POST /admin/bootstrap-link` pipeline (operator-only, localhost-bound). -7. Add `GET /admin/bootstrap-redeem` pipeline (token redemption). -8. Add `/admin/enrol-passkey` gating to require authenticated session with `role IN ('admin','super_admin')`. -9. Verify Phase 1 hotfix from PR-1 is in place on the branch (rebase if necessary). -10. End-to-end smoke: bootstrap-link → URL → redeem → JWT session → enrol passkey → log out → log back in with passkey → bootstrap link no longer needed. - -**Ships as PR-3 against `buymywishlist` after PR-2 (v0.3.0) is tagged + plugin.json sync workflow has bumped the manifest in the registry.** Depends on PR-1 + PR-2. - -### Phase II (deferred, post-merge) - -- Cross-product SSO IDP: `step.auth_jwt_issue` + `step.auth_jwt_verify` + `step.auth_jwks_serve` + `step.auth_refresh_token_*`, hosted JWKS endpoint module, key rotation hooks.

Likely the real 500 source. Engine bump rebuilds BMW image, validates plugin handshake, runs golden-path smoke. Lands FIRST, before nil-deref hotfix. | +| Existing magic-link table name | `magic_link_tokens` (verified at app.yaml:7109/:7175/:7221). Bootstrap pipeline ALTERs to add `purpose TEXT DEFAULT 'login'` column; reuses existing table. | +| `step.bmw.generate_token` retirement story | Honest: bespoke step survives Phase 3, survives Phase II until SSO IDP lands. Phase 3 adds an 11th call site (bootstrap-redeem). No claim of "deferred retirement" — it's "retained as foundation". | +| Role gating for `/admin/enrol-passkey` | Gate to `role = 'super_admin'` strictly (not `IN ('admin','super_admin')`). Tenant-admin must not be conflated with platform super-admin. BMW RBAC schema verified (`migrations/20260308000001_add_rbac_permissions.up.sql`): roles are `super_admin / admin / operator / viewer`. | +| Static bearer token for `/admin/bootstrap-link` | Explicitly **stopgap**. Listed as `BOOTSTRAP_OPERATOR_TOKEN` env var, NOT hardcoded; runbook says rotate per-deploy. Phase II followup: replace with mTLS or OS-process gate. | +| super_admins config source-of-truth | DB row, not config field. One-shot SQL seed in deploy runbook: `INSERT INTO users (email, role, ...) VALUES ('codingsloth@pm.me', 'super_admin', ...) ON CONFLICT (email) DO UPDATE SET role='super_admin' WHERE users.role NOT IN ('super_admin')`. Survives module-config rotation; no proto/plugin change needed. | +| Allowlist-miss response (timing oracle) | Bootstrap-link endpoint always returns the same 200 response (`{"sent": true, "message": "If your email is allowlisted, a link has been delivered"}`) regardless of allowlist match. Internal branching on `users.role='super_admin'` controls the actual magic-link mint. | +| Concurrent-redeem race | Magic-link verify already uses `UPDATE … WHERE used_at IS NULL RETURNING id` (app.yaml:7221), single-row atomic claim. Bootstrap-redeem reuses this; first redeem wins, second redeem hits the post-UPDATE empty-RETURNING path → 401. | +| Plugin RPC pattern (cycle 1) | Dropped. BMW pipeline mints magic link inline via existing `step.auth_magic_link_generate`. No new gRPC service, no plugin CLI, no plugin binary CLI-vs-handshake dual-mode. | +| Map-round-trip on `CredentialModuleConfig` | Not relevant (no new proto fields). | +| `super_admins` allowlist as plugin step (rev 2) | Dropped. YAGNI — single consumer (BMW). Phase II will extract when second consumer arrives. | + +## Phases & PR plan + +### PR-0 — BMW workflow engine pin bump (probable real 500 source) + +**Repo:** buymywishlist +**Depends on:** nothing. +**Risk class:** runtime — image rebuild, plugin handshake compatibility. + +1.

Strict-proto contract additions in Phase 2 are non-breaking — only adds new step + new optional proto field. No signature change to existing 25 steps. -3. BMW's existing CSRF middleware (if present) covers POST `/admin/bootstrap-link`. **If absent in BMW:** add a CSRF middleware to the admin pipeline group as a separate sub-task in PR-3. -4. BMW's ingress / reverse proxy can constrain `/admin/bootstrap-link` to localhost-bind. **If false:** rely on `X-Admin-Bootstrap-Token` header alone (declarative env var) plus rate-limit; document operator security model in BMW runbook. -5. BMW's existing magic-link table schema exists or can be added in one migration alongside the bootstrap pipeline. -6. Single super-admin email (`codingsloth@pm.me`) is acceptable for initial production; the proto list shape accommodates multiple. -7. Operator delivers magic-link URL via secure channel (1Password, Signal, in-person paste). Plugin not responsible for delivery. -8. workflow-compute's dashboard login codes stay untouched in this design. **If false:** scope creeps significantly; refuse and split. +1. **PR-0 verified before PR-1.** Engine bump from v0.20.1 to ≥v0.51.6 lands cleanly with no other code change required in BMW (no proto/struct-of-config breakage; existing pipelines using plugin steps remain semantically equivalent). *If false:* PR-0 grows to include any compatibility patches surfaced by `wfctl validate` + smoke; widens scope but doesn't change the plan. +2. **BMW ingress can localhost-bind `/admin/bootstrap-link`** or, failing that, the env-var-sourced bearer token + per-deploy rotation is acceptable as a stopgap. *If false:* operator must rotate token via Phase II proper hardening. +3. **`magic_link_tokens` table ALTER ADD COLUMN purpose is safe.** PostgreSQL is BMW's DB; ALTER ADD COLUMN with a DEFAULT is metadata-only (PG 11+, no full-table rewrite). Verified for the schema in current production. +4. **BMW deploy can run one-shot SQL seed** in a forward migration to insert the super-admin row. Existing migration runner (golang-migrate based, per the migrations/ directory pattern) supports this. +5. **`step.auth_password_hash` and `step.auth_password_verify` have input/output keys compatible with the bespoke `step.bmw.hash_password` / `step.bmw.verify_password` call shape.** Both wrap bcrypt; the plugin step is the canonical version. Confirmed by reading `workflow-plugin-auth/internal/step_password.go`. *If false:* PR-3 expands to YAML adapter glue. +6. **Operator delivers magic-link URL via secure channel** (1Password, Signal, direct console paste). Bootstrap pipeline not responsible for delivery. +7. **workflow-plugin-auth v0.2.4 stays as the BMW pin.** No plugin tag in this design. *If false:* unexpected scope creep; defer. ## Rollback (per change class) -| Phase | Change class | Rollback | +| PR | Change class | Rollback | |---|---|---| -| 0 | Engine verification (no code) | None needed; output is a paragraph in PR description. | -| 1 | BMW YAML changes (no engine/migration/version-pin changes) | Revert PR; signup/login returns to broken-500 baseline. | -| 2 | workflow-plugin-auth v0.3.0 release (1 new step, 1 proto config field, no migration) | Untag v0.3.0; consumers stay on v0.2.4.

Rev 1 was the original. ## Goal 1. Restore BuyMyWishlist (BMW) **signup AND login** (both currently HTTP 500). Root cause is suspected to be plugin-engine handshake failure (BMW pins workflow v0.20.1; existing in-use auth-plugin pipelines target v0.51.6-era strict-proto contracts), with template nil-derefs as secondary fragility surface. Both addressed. 2. Stand up an **admin bootstrap login flow** for BMW operator (`codingsloth@pm.me`): operator triggers magic-link mint via a localhost-bound BMW endpoint → URL → user redeems → JWT session → enrols passkey via existing passkey routes → subsequent logins use passkey; bootstrap is break-glass only. -3. Migrate BMW's two trivial password steps onto plugin equivalents (`step.bmw.hash_password` → `step.auth_password_hash`, `step.bmw.verify_password` → `step.auth_password_verify`). Bespoke `step.bmw.generate_token` retained (10 existing + 1 new call site in bootstrap-redeem = 11 total; no plugin replacement exists today). +3. Migrate ONE of BMW's two password-related bespoke steps onto its plugin equivalent (`step.bmw.verify_password` → `step.auth_password_verify`). **Keep** `step.bmw.hash_password` because the plugin's `step.auth_password_hash` uses `bcrypt.DefaultCost` (10) vs the bespoke cost=12 — silent security downgrade would result. Phase II opens a small plugin PR (v0.2.5) adding configurable `cost` field, then BMW can swap. Bespoke `step.bmw.generate_token` retained (9 existing + 1 new call site in bootstrap-redeem = 10 total; no plugin replacement exists today). 4. Document a forward path for cross-product SSO (issuer, JWKS endpoint, refresh tokens, JWT issue/verify) and plugin extraction of the bootstrap pattern as **Phase II**, triggered when a second consumer materialises (workflow-compute migrating its dashboard login codes is the most likely trigger). **Not built in this design.** ## Out of scope (deferred to Phase II or further) - **Plugin changes.** No new step types, no proto changes, no module-config additions, no v0.3.0 tag of `workflow-plugin-auth`. The existing v0.2.4 surface is sufficient (passkey + magic-link + password steps all already present). Plugin extraction of the bootstrap-pipeline pattern is deferred until a second consumer needs it. - **Cross-product SSO IDP surface** — `auth_jwt_issue` / `auth_jwt_verify` / `auth_jwks_serve` / refresh tokens.
