The architect singleton is enforced in ~12 call sites across in-memory state, two SQLite databases, the Tower instance manager, the dashboard API, and several CLI commands. Relaxing it in one shot would be a sprawling, hard-to-review change with no obvious checkpoint. + +This plan decomposes the work into **three sequential phases**, each ending in a demonstrable, committable state: + +- **Phase 1 — Storage and Tower data-model relaxation.** Schema migration, in-memory data structure change, every internal Tower call site updated to iterate over a collection rather than a scalar. No user-visible behavior change yet (every workspace still has one architect named `main`). +- **Phase 2 — Naming CLI + spawn-time identity capture.** A new CLI surface lets the user start a second named architect; Tower injects the spawning architect's name into the architect terminal's environment; `afx spawn` records `spawnedByArchitect` on each new builder row. +- **Phase 3 — Affinity-aware routing.** The `from` field already arrives at `handleSend()` but is dropped before resolution. Phase 3 plumbs it into the resolver, implements the three security rules from the spec (legacy-builder fallback, architect-gone fallback, cross-architect-address rejection), and lights up the full routing matrix. + +This ordering puts the user-visible win at the end: after Phase 3, a sibling-spawned builder's message lands where it should. Phases 1 and 2 are infrastructure that ship safely without exposing the feature, so they can be reviewed and merged independently if desired (single-PR or split-PR is the architect's call at the PR gate). + +## Success Metrics + +All criteria below come from `codev/specs/755-multi-architect-support-per-ar.md`. They roll up across phases; each phase's Acceptance Criteria carves out which subset that phase owns. + +- [ ] Two architect terminals run simultaneously in one workspace, with distinct names. +- [ ] First architect defaults to `main`; subsequent auto-number to `architect-2`, `architect-3`; explicit name overrides the default. +- [ ] A builder spawned by architect `A` records `spawnedByArchitect: "A"` on its row. +- [ ] `afx send architect` from a builder reaches **only** its spawning architect. +- [ ] Single-architect workspaces show zero behavior change; `/api/state` shape unchanged. +- [ ] Legacy builders (no `spawnedByArchitect`) route to `main` if present, else fail with the asserted error. +- [ ] Architect-gone builders route to `main` if present, else fail with the asserted error (distinct from legacy). +- [ ] Architect reconnect (new `terminalId`, same name) is transparent to builders. +- [ ] Non-builder `architect`-target sends route to `main` (or first), unchanged. +- [ ] Cross-architect address spoofing rejected with asserted error. +- [ ] All existing tests pass; new tests cover the full routing matrix. +- [ ] No latency regression in the single-architect path. +- [ ] Local `state.db` migration and global `terminal_sessions` backfill both safe and idempotent. + +## Phases (Machine Readable) + +```json +{ + "phases": [ + {"id": "phase_1", "title": "Storage and Tower data-model relaxation"}, + {"id": "phase_2", "title": "Naming CLI and spawn-time identity capture"}, + {"id": "phase_3", "title": "Affinity-aware routing"} + ] +} +``` + +## Phase Breakdown + +### Phase 1: Storage and Tower data-model relaxation + +**Dependencies**: None. + +#### Objectives + +- Let Tower store and operate on N architect terminals per workspace without breaking anything. +- Ship the SQLite migrations safely (local `state.db` schema change + global `terminal_sessions` data backfill). +- Touch every singleton call site the spec enumerates so that no code path silently retains the singleton assumption. +- **No user-visible change.** Every workspace still has one architect, named `main`. + +#### Deliverables + +- [ ] `ArchitectState` (`types.ts:37-41`) gains a `name: string` field. +- [ ] `Builder` (`types.ts:7-19`) gains `spawnedByArchitect?: string` (optional for backward-compat with old rows). +- [ ] `WorkspaceTerminals` (`tower-types.ts:33-39`) changes `architect?: string` to `architects: Map` (name → terminalId). +- [ ] `InstanceStatus.architectUrl` (`tower-types.ts:69`) scalar URL is preserved with a `main`-first shim — same v1 strategy as `/api/state`. The collection lives only inside Tower; the response collapses to `main`'s URL (or first registered) on the way out. Surfacing all architect URLs is deferred to issue #2. +- [ ] Local `state.db` migration (`v5` in `db/index.ts`): use the project's existing forward-only `_migrations` recipe (see `v3` for the precedent). Recreate the `architect` table via `CREATE TABLE architect_v2` → `INSERT SELECT 'main', ...` → `DROP architect` → `RENAME architect_v2 TO architect`. Preserve **every column default** from the current schema, especially `started_at TEXT NOT NULL DEFAULT (datetime('now'))` — Gemini's review caught that this was missing in the original plan pseudo-SQL. The new shape is `id TEXT PRIMARY KEY` storing the architect name. +- [ ] Local `state.db`: add `spawned_by_architect TEXT` column on the `builders` table via a separate `ALTER TABLE builders ADD COLUMN spawned_by_architect TEXT` migration step in `v5` (nullable). +- [ ] Global `~/.agent-farm/global.db` `terminal_sessions` backfill: `UPDATE terminal_sessions SET role_id = 'main' WHERE type = 'architect' AND role_id IS NULL`. Idempotent. Lives in the `v5` migration block alongside the schema work. +- [ ] **`state.ts` rewrites — call them out explicitly** (Claude's review flagged this was hidden in "round-trip the new fields"): + - `state.ts:27` — `SELECT * FROM architect WHERE id = 1` becomes `SELECT * FROM architect WHERE id = 'main'` for `loadState()`. The `DashboardState.architect` scalar shape is preserved (v1 contract); `loadState` returns `main`'s row (or null). + - `state.ts:54` — `setArchitect(architect)` deletes/upserts `id = 1`. It becomes the **`main`-only setter** — `WHERE id = 'main'` — preserving the existing single-architect call sites unchanged. A new `setArchitectByName(name, state)` is added for the multi-architect path Tower uses internally. Phase 2's CLI calls the new function; existing callers (`workspace start`, `stop`) keep calling `setArchitect()`. + - `state.ts:275` — `DELETE FROM architect` (the bulk-clear path used by `clearState`) stays as-is — it's already correct for a multi-row table. + - `state.ts:289` — the duplicate `SELECT * FROM architect WHERE id = 1` (another singleton hit) becomes `WHERE id = 'main'` with the same shim semantics as `loadState`. +- [ ] **`db/migrate.ts:40` rewrite** (Claude's review caught this was missing from the original files-touched list): the JSON-to-SQLite migration helper currently inserts `VALUES (1, @pid, @port, @cmd, @startedAt)` for the architect row. Change to `VALUES ('main', ...)`. This is the legacy path used during the JSON → SQLite migration; with the schema change above, it must insert the right primary-key value. +- [ ] Every Tower call site listed in the spec's References updated to iterate over the collection. The activation guard at `tower-instances.ts:354` is relaxed (multi-architect creation is now permitted; default name `main` is supplied for now). **The reconnect/rehydration path at `tower-terminals.ts:642` is updated alongside the create-time paths** — Codex's review flagged that if reconnect logic still assumes singleton, an architect terminal that crashes and is restored will be miscategorized. +- [ ] `/api/state` response shape preserved: continues to return `state.architect` as a scalar, populated from the `main` entry (or first, if `main` absent). Structurally identical to today's response (key shape and types unchanged). Dashboard and VSCode extension untouched. +- [ ] `resolveAgentInWorkspace` (`tower-messages.ts:191-200`) updated to look up the architect by name from the collection. With only one architect (`main`) registered after Phase 1, behavior is unchanged from today. +- [ ] CI guardrail test: a grep-based unit test that fails if `entry.architect` (singular accessor) appears in any source file outside the documented allowed shim sites. Stops future contributors from re-introducing the singleton. +- [ ] Migration tests (one for the local schema change, one for the global `terminal_sessions` backfill). +- [ ] All existing tests pass with zero modifications, except for tests that directly inspect the old `entry.architect` scalar — those update to the new collection shape. + +#### Implementation Details + +**SQLite migration (local `state.db`).** The current schema is: + +```sql +CREATE TABLE IF NOT EXISTS architect ( + id INTEGER PRIMARY KEY CHECK (id = 1), + pid INTEGER NOT NULL, + port INTEGER NOT NULL, + cmd TEXT NOT NULL, + started_at TEXT NOT NULL DEFAULT (datetime('now')), + terminal_id TEXT +); +``` + +SQLite cannot drop a CHECK constraint in place, so the migration follows the standard `CREATE TABLE new`, `INSERT SELECT`, `DROP TABLE old`, `ALTER TABLE new RENAME TO old` recipe — the same pattern already used by migrations `v3` and `v4` in `db/index.ts`. The new schema **must preserve every column default**, including `DEFAULT (datetime('now'))` on `started_at`: + +```sql +CREATE TABLE architect_v2 ( + id TEXT PRIMARY KEY, -- architect name (e.g., 'main', 'architect-2', 'sibling') + pid INTEGER NOT NULL, + port INTEGER NOT NULL, + cmd TEXT NOT NULL, + started_at TEXT NOT NULL DEFAULT (datetime('now')), + terminal_id TEXT +); +INSERT INTO architect_v2 (id, pid, port, cmd, started_at, terminal_id) + SELECT 'main', pid, port, cmd, started_at, terminal_id FROM architect; +DROP TABLE architect; +ALTER TABLE architect_v2 RENAME TO architect; +``` + +The migration is registered as `v5` in `db/index.ts`, using the existing `_migrations`-versioned forward-only pattern. There is no rollback SQL — the project's existing migration framework is forward-only, and this plan follows that convention. Recovery is by reverting the PR (which restores the prior code); a workspace that already migrated would need its `state.db` restored from the user's prior backup (or accept that the row's `id` is now `'main'` instead of `1`). This is the same recovery story the project already accepts for `v3` and `v4`. + +**SQLite migration (`builders` table).** Add `spawned_by_architect TEXT` as a nullable column: + +```sql +ALTER TABLE builders ADD COLUMN spawned_by_architect TEXT; +``` + +Trivial — single `ALTER`. + +**`terminal_sessions` backfill (global `~/.agent-farm/global.db`).** No schema change; data only: + +```sql +UPDATE terminal_sessions + SET role_id = 'main' + WHERE type = 'architect' AND role_id IS NULL; +``` + +Idempotent. + +**In-memory shape.** `WorkspaceTerminals.architects` is a `Map` (name → terminalId). The plural plus the keyed access pattern makes wrong-singleton-y code (`entry.architects` followed by a string method) fail loudly at the type level rather than producing wrong-but-plausible runtime behavior. + +**Dashboard API shim.** In `tower-routes.ts:1411-1418`, the existing code populates `state.architect` from `entry.architect`. Phase 1 changes this to: + +```ts +const mainArchitectId = entry.architects.get('main') ?? entry.architects.values().next().value; +if (mainArchitectId) { + const session = manager.getSession(mainArchitectId); + if (session) state.architect = { ... }; +} +``` + +This shim is intentional and documented in the spec (item 7). + +**Files touched**: +- `packages/codev/src/agent-farm/types.ts` +- `packages/codev/src/agent-farm/servers/tower-types.ts` +- `packages/codev/src/agent-farm/db/schema.ts` +- `packages/codev/src/agent-farm/db/migrate.ts` +- `packages/codev/src/agent-farm/state.ts` +- `packages/codev/src/agent-farm/servers/tower-instances.ts` +- `packages/codev/src/agent-farm/servers/tower-routes.ts` +- `packages/codev/src/agent-farm/servers/tower-terminals.ts` +- `packages/codev/src/agent-farm/servers/tower-tunnel.ts` +- `packages/codev/src/agent-farm/servers/tower-messages.ts` +- `packages/codev/src/agent-farm/commands/stop.ts` +- `packages/codev/src/agent-farm/commands/status.ts` +- Test files mirroring each of the above. + +#### Acceptance Criteria + +- [ ] Migrations run forward cleanly on a fresh DB and on a pre-existing DB. +- [ ] Migration unit tests pass: pre-state with `id = 1` architect row + null `role_id` → post-state with `id = 'main'` and `role_id = 'main'`. +- [ ] All existing tests pass. +- [ ] `entry.architect` (singular) is not used anywhere in source code (CI guardrail). +- [ ] A single-architect workspace's `/api/state` response is byte-identical to before (after dashboard shim). +- [ ] 3-way consultation reviewed and feedback addressed. + +#### Test Plan + +- **Unit tests**: + - Migration test for local `architect` table (one row → renamed and rekeyed). + - Migration test for global `terminal_sessions` (null `role_id` → `'main'`; non-null untouched; non-architect rows untouched; idempotent on re-run). + - `loadState` round-trip with multiple architect rows in `state.db`. + - `WorkspaceTerminals.architects` collection access (add, get, delete, iterate). +- **Integration tests**: + - Tower starts up against a freshly migrated DB and serves `/api/state` with the expected scalar shape. + - Workspace stop kills the single architect terminal correctly via the new iteration code path. +- **Manual testing**: + - Spin up a clean workspace; verify the architect tab appears in the dashboard and the architect terminal works exactly as before. + +#### Rollback Strategy + +Codev's migration framework is forward-only: `_migrations` records applied versions, but there is no reverse-SQL machinery (verified against the existing `v3` and `v4` migrations in `db/index.ts`, which use the same `CREATE/INSERT/DROP/RENAME` pattern without reverse SQL). The recovery path is: + +1. **In-PR rollback (before merge):** revert the commit, drop the new `_migrations` row manually if needed for testing. +2. **Post-merge rollback:** revert the code-level changes. Workspaces that already ran the `v5` migration would have their `architect.id` rekeyed from `1` to `'main'`; subsequent code (the reverted version) would still find the row via its old query (`WHERE id = 1` would fail to find `'main'`). For affected users, the recovery is to either re-apply this feature's code or recreate the `state.db` (the architect terminal will be re-registered on next workspace start). + +This follows the project's existing convention. The risk is bounded: `state.db` is per-workspace, recreatable, and contains no irrecoverable user data. + +#### Risks + +- **Risk**: A test or external consumer reads `entry.architect` (singular) directly and silently breaks. → **Mitigation**: TS compile error from the type change (renaming the field forces every call site to update); CI guardrail catches new occurrences. +- **Risk**: The migration loses the existing architect row in workspaces with a long history. → **Mitigation**: Migration test covers the pre-state explicitly; the rebuild table SQL preserves all columns including defaults; an integration test boots Tower against a migrated DB and verifies the architect is still there. +- **Risk**: The global `terminal_sessions` backfill races with an active Tower writing new rows. → **Mitigation**: The backfill runs as part of Tower startup before serving connections; documented in the migrate code. +- **Risk** (Codex review): The architect-name flow updates create-time paths in `tower-instances.ts` but misses the reconnect/rehydration path at `tower-terminals.ts:642`. An architect terminal that crashes and is restored would lose its name binding and route to the wrong place silently. → **Mitigation**: explicit deliverable above (rehydration path included); test scenario in Phase 3 (architect reconnect) catches a regression here. + +--- + +### Phase 2: Naming CLI and spawn-time identity capture + +**Dependencies**: Phase 1. + +#### Objectives + +- Give the user a way to start a second named, **Tower-registered** architect terminal in an active workspace. +- Make the spawning architect's name observable to `afx spawn` via the architect terminal's environment. +- Record `spawnedByArchitect` on every new builder row. +- **Still no routing change.** Sends to `architect` continue to land on `main` (or first registered); this phase only changes *which name* gets attached to each builder. + +#### The existing `afx architect` command — IMPORTANT + +Both Codex's and Claude's reviews caught that `packages/codev/src/agent-farm/commands/architect.ts` **already exists** and does something the original plan ignored. The existing command: + +- Runs a local Claude session in **the current shell** (`stdio: 'inherit'`), not as a Tower-managed PTY. +- Explicitly documented as "**No Tower dependency**" — works in any directory, even outside a workspace. +- Used today by humans who want to drop into an architect session from a plain terminal. + +This command **stays as-is in Phase 2.** The spec's example `afx architect --name ` is the architect's preferred *user-facing surface*, but the existing command's no-Tower contract is load-bearing for current users. The new functionality cannot be a flag on a command that explicitly disclaims Tower involvement. + +**The Phase 2 commitment:** introduce a separate Tower-aware subcommand path for registering a named architect terminal. Working name: **`afx workspace add-architect [--name ]`** — keeps architect-management under the `workspace` noun (which already owns `start`/`stop`/`rename`). If review pushes back on this shape at PR time, the implementation is a thin CLI handler that delegates to a Tower client method, so renaming is a small refactor. The architect can also adopt their preferred shape (`afx architect --name`) at PR time by repurposing `commands/architect.ts` into a dual-mode command — that's a small, contained change vs. the current plan path. + +#### Deliverables + +- [ ] New subcommand wired into `afx` CLI: **`afx workspace add-architect [--name ]`**. Registers a new architect terminal with Tower in the active workspace. Without `--name`, Tower auto-assigns the next available `architect-` (smallest unused integer ≥ 2). With `--name`, validates and uses the supplied name. +- [ ] Existing `afx architect` (local-Claude, non-Tower) command is **unchanged**. +- [ ] Tower client method (`packages/core/src/tower-client.ts`) for the new Tower API. +- [ ] Tower HTTP route handler in `tower-routes.ts` that calls into `tower-instances.ts` (which already creates architect terminals; the new path just supplies a name + writes the `architect` SQLite row keyed by name). +- [ ] Name validation: `[a-z][a-z0-9-]*`, max 64 chars. The literal string `main` is also valid (no special-casing). Re-using a registered name in the same workspace is rejected with a clear error. +- [ ] Tower injects an env var (`CODEV_ARCHITECT_NAME=`) into the architect terminal's shell at PTY-start time. The default name `main` is injected for the first architect (the one started by `afx workspace start`); auto-numbered or explicit names are injected for subsequent architects. The variable name is documented in `codev/resources/commands/agent-farm.md`. +- [ ] `afx spawn` reads the env var to obtain the spawning architect's name and persists it on the new builder row. +- [ ] `afx status` continues to show a flat builder list with no filtering; the `spawnedByArchitect` column is **not** added in v1 (per spec — that's issue #2). Plan resists scope creep here. +- [ ] Unit tests for: name validation, auto-numbering algorithm, name-collision rejection, env-var detection (set/unset/empty), default-fallback to `main`. +- [ ] Integration test referencing the existing `packages/codev/src/agent-farm/__tests__/af-architect.test.ts` patterns (Claude's review pointed at this file as the right precedent). + +#### Implementation Details + +**Spawn-time detection.** `commands/spawn.ts:439` calls `upsertBuilder`. The diff: + +```ts +const spawnedByArchitect = process.env.CODEV_ARCHITECT_NAME ?? 'main'; +upsertBuilder({ ..., spawnedByArchitect }); +``` + +Two lines. The default-to-`main` keeps `afx spawn` from the workspace root (outside any architect terminal) working unchanged. SQLite is synchronous and atomic, so two `afx spawn` calls run from two different architect terminals at the same instant cannot interleave their `upsertBuilder` writes — addressed in the Risks subsection below. + +**Auto-numbering.** "Smallest unused integer ≥ 2" — implemented as a single pass over Tower's in-memory `entry.architects` keys. Tiebreak: starting `architect-2`, killing it, starting another with no name → the new one is `architect-2` again (the collection no longer contains it). This matches the spec's smallest-unused-integer semantics. Unit-tested explicitly. + +**Env var injection.** Tower already injects environment variables into architect terminals via the harness mechanism (`agent-farm/types.ts:159-173`). Phase 2 adds `CODEV_ARCHITECT_NAME=` to every architect terminal's environment at PTY creation. The variable is reserved under the `CODEV_*` prefix. + +**Why not extend `commands/architect.ts`?** Because the existing command's contract is "no Tower dependency." Adding a `--name` flag that requires Tower would break that contract for users who run `afx architect` in directories that aren't Codev workspaces. The clean separation — local-mode in `commands/architect.ts`, Tower-mode in `commands/workspace.ts` (or a new file) — preserves both use cases without introducing flag-conditional behavior. + +**Files touched**: +- `packages/codev/src/agent-farm/cli.ts` (subcommand registration for `add-architect`) +- `packages/codev/src/agent-farm/commands/workspace.ts` (extended with the `add-architect` handler; if a single command file proves unwieldy, factor into `commands/workspace-add-architect.ts`) +- `packages/codev/src/agent-farm/commands/spawn.ts:439` (read `CODEV_ARCHITECT_NAME`, pass to `upsertBuilder`) +- `packages/codev/src/agent-farm/state.ts` (`upsertBuilder` signature includes `spawnedByArchitect`; ensure the SQL `INSERT` covers the new column) +- `packages/codev/src/agent-farm/servers/tower-instances.ts` (architect-create accepts a `name` param + auto-assigns when omitted; PTY env injection includes `CODEV_ARCHITECT_NAME`) +- `packages/codev/src/agent-farm/servers/tower-routes.ts` (HTTP route for the architect-create API) +- `packages/core/src/tower-client.ts` (client method for the new route) +- Tests for each. + +**Files explicitly NOT touched**: +- `packages/codev/src/agent-farm/commands/architect.ts` — kept as-is to preserve the no-Tower contract. + +#### Acceptance Criteria + +- [ ] Starting a second architect via `afx architect --name sibling` registers `sibling` in Tower's `architects` collection; `afx status` shows it (if the v1 plan-phase decision is to surface it — confirm in 3-way review). +- [ ] Starting a second architect without `--name` gets `architect-2`; a third gets `architect-3`. +- [ ] Re-using an existing name (or `main`) is rejected with a clear error. +- [ ] Invalid names (uppercase, spaces, leading digit, length > 64) are rejected. +- [ ] A builder spawned from inside an architect terminal whose `CODEV_ARCHITECT_NAME=sibling` records `spawnedByArchitect: 'sibling'` in `state.db`. +- [ ] A builder spawned from the workspace root (no env var) records `spawnedByArchitect: 'main'`. +- [ ] All Phase 1 acceptance criteria continue to hold. +- [ ] 3-way consultation reviewed. + +#### Test Plan + +- **Unit tests**: + - Name validation (positive + negative). + - Auto-numbering algorithm (smallest-unused-integer with gaps). + - `commands/spawn.ts` env-var detection (set, unset, empty-string). +- **Integration tests**: + - Start architect via CLI, observe it in Tower's state. + - Spawn a builder from the new architect terminal, observe `spawned_by_architect` column in `state.db`. + - Collision rejection (start `sibling`, attempt to start another `sibling`, observe error). +- **Manual testing**: + - Run two architect terminals side by side. Confirm both show in `afx status`. Send messages — they still all go to `main` (routing change is Phase 3). + +#### Rollback Strategy + +Revert the new CLI subcommand and the env-var injection in Tower. The `spawned_by_architect` column from Phase 1 stays; existing data is preserved. + +#### Risks + +- **Risk**: The env-var injection conflicts with user-supplied env vars in their shell config. → **Mitigation**: `CODEV_*` prefix is reserved per existing convention; documented as Codev-controlled. +- **Risk** (Codex + Claude review): the existing `afx architect` command's no-Tower contract conflicts with the multi-architect feature. → **Mitigation**: Phase 2 introduces a separate Tower-aware subcommand (`afx workspace add-architect`) rather than extending the existing command. Documented explicitly above. +- **Risk**: PR-time pushback on the `afx workspace add-architect` shape (e.g., architect wants `afx architect --name ` after all). → **Mitigation**: the implementation is a thin handler delegating to a Tower client method; renaming or aliasing the command is a small contained change. The architect's spec example is followed in spirit (a way to start a named architect) even if the exact verb differs. +- **Risk**: Auto-numbering algorithm has subtle off-by-one. → **Mitigation**: Unit test with explicit cases (empty workspace, `main` only, `main + architect-2`, `main + architect-3` with `architect-2` missing). +- **Risk** (Claude review): two `afx spawn` commands run simultaneously from different architect terminals could race in `upsertBuilder`. → **Mitigation**: `state.db` writes go through `better-sqlite3` which is synchronous and atomic at the statement level; each `INSERT` completes before the next can begin. Test scenario: spawn two builders concurrently from two architects; assert both rows have the correct `spawned_by_architect` after the dust settles. + +--- + +### Phase 3: Affinity-aware routing + +**Dependencies**: Phase 2. + +#### Objectives + +- When a builder runs `afx send architect`, deliver the message to that builder's spawning architect — not the singleton. +- Enforce the three security rules from the spec: legacy-builder fallback, architect-gone fallback, cross-architect-address rejection (with exact error texts). +- Light up the full routing test matrix from the spec. +- **This is the user-visible win.** After Phase 3, the feature works end-to-end. + +#### Deliverables + +- [ ] `from` (sender identity) plumbed from `handleSend()` into the resolution layer. **Resolver-signature decision** (Codex's review asked for this commitment): widen `resolveTarget` itself to `(target, fallbackWorkspace?, sender?)` rather than introducing a separate `/api/send`-only wrapper. Rationale: `resolveTarget` is the single entry point for address resolution; pulling sender-awareness into a parallel wrapper would fork the resolution code path and force every future caller to choose between two functions. The `sender` parameter is **optional with a clear default branch** — cron and other non-builder callers pass nothing, behavior is unchanged for them. +- [ ] `resolveAgentInWorkspace` (or its successor) implements: + 1. **Sender is a builder, target is `architect`** → look up sender's `spawnedByArchitect` in `state.db`; if the named architect is registered in `entry.architects`, route there. Otherwise apply architect-gone fallback (route to `main` if present; else error with the spec's architect-gone message). + 2. **Sender is not a builder, target is `architect`** → route to `main` if present; else route to the first registered architect. + 3. **Sender is a builder, target is `architect:`** and ` !== sender's spawnedByArchitect` → reject with the spec's address-spoofing error message. + 4. **Legacy builder (no `spawnedByArchitect` row)** → route to `main` if present; else error with the spec's legacy-builder message. +- [ ] Error messages match the spec verbatim (asserted by test). +- [ ] `tower-cron.ts` and any other non-builder architect-target sender continues to resolve to `main` (no behavior change for cron). +- [ ] Builder-context detection at the resolver layer — distinguishing builder-from from architect-from. **Detection rule** (Gemini's review caught a better predicate): query `state.db` for `SELECT spawned_by_architect FROM builders WHERE id = ?` using the `from` value; if a row exists, the sender is a builder context. **Do not** use `entry.builders.has(from)` — that's live-terminal state, which is empty for completed builders whose terminal sessions have ended but whose `state.db` rows still exist (e.g., a human operator running `afx send architect` from inside a finished builder's worktree). +- [ ] Architect-reconnect handling: when an architect terminal dies and is recreated with the same name (new `terminalId`), routing seamlessly picks up the new `terminalId` from `entry.architects.get(name)`.

This avoids an import cycle between `tower-messages.ts` and the higher-level `state.ts` module that owns `loadState`/`upsertBuilder`. The read-only handle is opened on demand per call (cheap), or cached on the workspace entry (faster) — Phase 3 implementation picks one based on the latency benchmark. + +**Address-spoofing detection nuance.** The pseudocode above rejects `architect:` only when the sender is a builder *with a known `spawned_by_architect`*. A non-builder sender (cron, workspace-root manual send) can target any specific architect by name — there's no spoofing concept for non-builders, since their identity isn't the basis for routing. + +**Files touched**: +- `packages/codev/src/agent-farm/servers/tower-messages.ts` (resolver core) +- `packages/codev/src/agent-farm/servers/tower-routes.ts` (`handleSend` plumbing at line 854) +- `packages/codev/src/agent-farm/state.ts` (helper to look up a builder's `spawnedByArchitect`) +- New error-construction module (or inline in `tower-messages.ts`) for the asserted-verbatim error texts. +- Tests covering every spec scenario. + +#### Acceptance Criteria + +- [ ] **Single-architect baseline (spec scenario 1)**: builder → `architect` → `main`.

Spawn a builder from each. Have each builder send `afx send architect "hi from "`. Confirm each architect terminal sees only its own builder's message. + +#### Rollback Strategy + +Revert the resolver changes; sends fall back to the singleton-style resolution.

A dedicated subsection explains the distinction and why a flag-conditional dual-mode command was rejected. +2. **`state.ts` hardcoded `WHERE id = 1` SQL paths.** Both Codex and Claude flagged that "round-trip the new fields" was hand-wavy. **Fix**: Phase 1 deliverables now explicitly enumerate the four `state.ts` lines that need rewriting (`:27`, `:54`, `:275`, `:289`), with the chosen semantics for each (e.g., `loadState` becomes a `main`-only shim; a separate `setArchitectByName` adds the multi path). +3. **Rollback strategy didn't match the actual migration framework.** Codex caught that `db/migrate.ts` is a one-way JSON→SQLite helper and `_migrations` is forward-only with no reverse SQL. **Fix**: Phase 1 Rollback Strategy rewritten to match the project's actual convention (forward-only; recovery is "revert the PR + accept the rekeyed row" or restore from prior `state.db` backup). The plan now references `v3` and `v4` migrations as the precedent pattern. + +**Codex-only findings — addressed:** + +- **Phase 3 resolver-signature commitment.** The plan now commits explicitly to widening `resolveTarget(target, fallbackWorkspace?, sender?)` rather than introducing a parallel `/api/send`-only wrapper.

Surfacing all architect URLs is deferred to issue #2. +- **`annotations.parent_id` for architect-parented annotations** (Claude flagged this as a known gap). **Status**: explicitly noted as out of scope for v1 (no annotation behavior changes); when issue #2 lands, a follow-up amendment can populate `parent_id` with the architect's name for architect-owned annotations. No changes to the `annotations` table in this work. +- **"byte-identical" → "structurally identical"** on `/api/state` shape comparison. Adjusted. +- **Reference `af-architect.test.ts`** as the precedent for Phase 2's test patterns. Added to deliverables. +- **Concurrent `afx spawn` race** in `upsertBuilder`.

This means the reporter doesn't get value until all three phases land — but each individual phase commits cleanly and could ship in isolation if needed. The architect decides at PR time whether to bundle all three into one PR or split. +- The spec's "Out of scope" items (#2–#5 from issue #755) stay out of scope through all three phases. Plan-phase discipline matters: a small "while we're here" addition to Phase 2 (e.g., adding `spawnedByArchitect` to `afx status` output) is exactly the scope creep the spec called out as a risk. +- The CI guardrail test from Phase 1 is the most important non-obvious deliverable.

The duplicate-Architect-tab guarantee is enforced by code review and by the v1 contract — adding a dedicated unit test for `getTerminalsForWorkspace` would require a substantial mock harness (SQLite + TerminalManager + the deps wiring) that's out of proportion for this targeted invariant. The CI guardrail test from the plan catches any code that re-introduces `entry.architect` (singular) accesses, which covers the underlying class of regression.

Real bug. + +**Verification**: `stop.ts:55-62` used `state.architect?.terminalId` (the scalar shim — `main` first, then first-registered). In a multi-architect workspace, this only kills one architect; siblings leak as orphan processes after the tower-deactivation path fails. + +**Change**: Replaced the singleton kill with a `for (const architect of getArchitects())` loop that kills every registered architect's terminal.

The deliverable also says "**Preserve every column default** ... especially `started_at TEXT NOT NULL DEFAULT (datetime('now'))` — Gemini's review caught that this was missing." + +### G2. Phase 3 single-architect fast-path + +> To strictly satisfy the spec's "Latency parity" requirement for single-architect workspaces, you can add a fast-path at the top of the `architect` resolution block. + +**Status**: Adopted. + +**Change**: Phase 3 resolver pseudocode now starts with: + +```ts +if (entry.architects.size === 1 && entry.architects.has('main')) { + return { terminalId: entry.architects.get('main')!, ... }; +} +``` + +This bypasses the SQLite read entirely for solo-architect users. Since all fallback rules end at `main` anyway, this is functionally identical for the single-architect case and guarantees latency parity. + +### G3. Builder-context detection via `state.db` row, not `entry.builders` + +> If a human operator runs `afx send architect` from the worktree of a *completed* builder (whose terminal session has ended), `entry.builders` will no longer contain that ID.

Better predicate. + +**Change**: Phase 3's builder-context detection now keys on `state.db` row presence — `lookupBuilderSpawningArchitect` returns: +- `string` — recorded `spawned_by_architect` (builder context with explicit name). +- `null` — row exists but `spawned_by_architect` is NULL (legacy row). +- `undefined` — no row exists (not a builder). + +This three-valued return cleanly distinguishes "legacy builder" from "non-builder sender" without consulting live terminal state. + +### G4 (implicit, from G3). Cycle avoidance + +Gemini also pointed out that `lookupBuilderSpawningArchitect` can avoid a `tower-messages.ts` → `state.ts` import cycle by opening a read-only SQLite handle directly, mirroring `servers/overview.ts`. + +**Change**: Phase 3's Implementation Details explicitly adopts this pattern. + +--- + +## Items I did NOT change (and why) + +- **Working name `afx workspace add-architect`.** The architect's spec example was `afx architect --name `. I went a different direction (a new noun under `workspace`) because extending the existing local-mode `afx architect` would break its no-Tower contract. The plan is explicit about this trade-off and acknowledges the architect can adopt their original phrasing at PR time with a small contained refactor (Phase 2 Risks subsection). +- **Phase ordering (1 → 2 → 3).** No reviewer pushed back. The user-visible win lands last by design. +- **No new CLI for `afx status --architect ` filter.** Out of scope per the spec (deferred to issue #2).

The updates are captured in commit `62446542` ("[Spec 755] Specification with multi-agent review"). The spec's "Expert Consultation" section now mirrors this rebuttal in summarized form for future readers. + +--- + +## Codex — REQUEST_CHANGES + +### C1. `architect:all` syntax conflicts with the existing address parser + +> The proposed `architect:all` broadcast syntax conflicts with the existing address parser: `parseAddress()` treats `x:y` as `{ project: x, agent: y }`, so `architect:all` currently means project=`architect`, agent=`all`, not a special architect address. Pick a syntax that fits current grammar or explicitly require grammar changes. + +**Status**: Addressed. + +**Change**: Pinned broadcast syntax to `architects` (plural, no colon) in Scope item 5. The Open Question is marked Resolved. Moving the decision into the spec rather than deferring it to the plan removes a parser-level surprise that could derail implementation. + +### C2. Migration claim incorrect against the actual schema + +> The spec says the architect-table migration should add uniqueness on `(workspace_path, architect_id)`, but the verified local `architect` table in `packages/codev/src/agent-farm/db/schema.ts` has no `workspace_path` column because `state.db` is already per-workspace. That migration requirement is currently incorrect and should be rewritten against the actual schema. + +**Status**: Addressed. Codex is correct — `state.db` is per-workspace. + +**Change**: Scope item 2 now specifies: drop `CHECK (id = 1)`, change `id` to `TEXT PRIMARY KEY` storing the `architectId`. No `workspace_path` column. The Constraints section explicitly calls this out as a correction of the prior draft. Success Criteria includes a migration test that rekeys the existing row's `id` to `"main"`. + +### C3. More singleton surfaces beyond the three named + +> Multi-architect support affects more than the three singleton points named in the spec. Verified singleton surfaces also include `DashboardState.architect`, `ArchitectState`, `loadState()/setArchitect()`, `InstanceStatus.architectUrl`, and terminal list generation that hardcodes tab/id `'architect'`. The spec should either include these as in-scope compatibility surfaces or explicitly declare the intended v1 behavior for UI/state APIs. + +**Status**: Addressed. + +**Change**: Scope item 2 now enumerates **all** known singleton call sites (in-memory map, local SQLite, global SQLite `terminal_sessions`, activation guard, multiple teardown paths, dashboard state, tunnel map, CLI commands, migration code). References section mirrors the list with file/line citations. Scope item 7 makes an explicit decision: `/api/state` response shape stays scalar in v1 (collapsed to `"main"` or first architect), so the dashboard and VSCode extension do not need updates. Multi-architect UI is deferred to issue #2. + +### C4. Routed resolution underspecified at the API boundary + +> Verified `resolveTarget(to, workspace)` does not currently receive sender identity, while `handleSend()` does receive `from`. The spec should state whether sender-aware routing is a requirement on the resolver contract itself or whether routing may happen one layer up. + +**Status**: Addressed. + +**Change**: Solution Approach (layer 3) now explicitly says v1 plumbs `from` from `handleSend` into the resolution layer, and acknowledges that whether to widen `resolveTarget`'s signature or add a sibling builder-context resolver is a **plan-phase decision**. Constraints reinforces this. The spec commits to the requirement (sender identity reaches the resolver) without over-specifying the API shape. + +### C5. "No other code path uses `architect` as a target" assumption is false + +> The "no other code path uses literal `architect` as a resolution target" assumption is not true in the repo as written; there are other architect-targeted flows such as cron/task routing. The spec should clarify that only builder-originated sends become architect-affinity-aware, while non-builder `architect` sends keep resolving to the default/main architect unless explicitly broadcast. + +**Status**: Addressed. The original Assumptions bullet was inaccurate. + +**Change**: Assumptions section rewritten to state that builder-originated `afx send architect` is the affinity-aware path, while non-builder paths (cron-originated messages, `afx send architect` from the workspace root) keep the existing "route to `"main"` (or first registered)" semantics. Scope item 4 makes the same statement in normative form. Success Criteria adds a test scenario (#11) for non-builder architect-target sends. + +### C6. Legacy fallback rule needs sharper success criteria + +> The spec proposes "route legacy builders to `main` if present, else error," which is good, but the success criteria do not currently require that exact behavior, nor do they define the operator-facing error text/handling when `main` is absent. + +**Status**: Addressed. + +**Change**: Security Considerations now spells out three distinct fallback rules with their exact operator-facing error messages (legacy-builder-no-`main`, architect-gone-no-`main`, address-spoofing-rejection). Success Criteria now requires those error texts to be asserted by test. Test Scenarios includes both the present-`main` and absent-`main` variants of each failure mode (scenarios 4–7 and 10). + +--- + +## Gemini — REQUEST_CHANGES + +### G1. Incorrect local schema migration + +> The `Constraints` section states the migration for the `architect` table needs a `(workspace_path, architect_id)` uniqueness constraint. This is technically incorrect... The migration should simply drop the `CHECK (id = 1)` constraint and redefine the primary key to hold the string identifier (e.g., `id TEXT PRIMARY KEY`). + +**Status**: Addressed. Duplicate of C2; see that response. Both Gemini's and Codex's fix is what I adopted: `id TEXT PRIMARY KEY` after dropping the singleton check. + +### G2. Missed 4th singleton home (global DB) + +> The spec correctly identifies 3 singleton homes but misses a critical 4th: the `terminal_sessions` table in `global.db`... Currently, for rows where `type = 'architect'`, the `role_id` column is explicitly documented as `(null for architect)`. To support multiple architects and ensure Tower recovery doesn't collapse them, the `role_id` column must be updated to store the `architectId`. + +**Status**: Addressed. This is a real gap that I missed in the first draft. + +**Change**: Scope item 2 includes the `terminal_sessions.role_id` change explicitly: schema unchanged, but the data-shape contract changes to "`role_id` is no longer null for architect rows; it stores the `architectId`." Constraints describes this as a "data-shape contract change" rather than a schema change. Success Criteria adds a backfill migration test (non-functional test #3) that idempotently sets `role_id = 'main'` for existing architect rows where `role_id IS NULL` and leaves other rows untouched. + +### G3. Missing sender context in routing + +> While the Tower `/api/send` endpoint extracts the `from` field (the sender's identity), it drops it entirely when invoking `resolveTarget(to, workspace)`. The spec should explicitly note that the `from` identity must be plumbed into the routing layer. + +**Status**: Addressed. Duplicate of C4; see that response. + +**Change**: Current State section now includes a precise description of where `from` is dropped (line 854 of `tower-routes.ts`), so future readers see exactly the bug being fixed. Solution Approach and Constraints make the plumbing requirement normative. + +### G4. (Minor) `architects` plural avoids parser ambiguity + +> `architect:all` conflicts conceptually with the existing `[project:]agent` parser grammar... `architects` (plural) safely avoids this parser ambiguity. + +**Status**: Addressed. Adopted Gemini's recommendation as the final decision. See C1. + +--- + +## Claude — COMMENT + +Claude returned COMMENT (not REQUEST_CHANGES), but its findings are all actionable and worth addressing. I treated them as if they were REQUEST_CHANGES. + +### Cl1. Dashboard / VSCode extension API shape change unacknowledged + +> The `/api/state` response currently returns `architect: { terminalId, persistent }` as a single object. Multiple architects will change this API surface. The spec should state whether the dashboard is updated in v1 or whether the API deliberately collapses to the "first/main" architect for backward compat. + +**Status**: Addressed. This was a real gap. + +**Change**: Scope item 7 makes an explicit decision: v1 deliberately keeps the existing scalar shape of `state.architect` in `/api/state`, populated with `main` (or first registered if `main` is absent). The dashboard and VSCode extension see one architect tab, identical to today. Multi-architect UI is deferred to issue #2. Risks table includes "Dashboard / VSCode extension breaks due to `/api/state` shape change" with the v1 decision as its mitigation. + +### Cl2. Fourth singleton enforcement point at `tower-instances.ts:354` + +> `tower-instances.ts:354` (`if (!entry.architect)`) prevents creating a second architect terminal at activation time. The spec lists three singleton homes but this guard is a fourth that must be relaxed in lockstep. + +**Status**: Addressed. + +**Change**: Scope item 2 explicitly enumerates `tower-instances.ts:354,416,452,529-532` (activation guard, create paths, teardown). I also walked the codebase further and added `tower-routes.ts:1411-1418,1853-1855,1882-1884`, `tower-terminals.ts:289-290,642`, `tower-tunnel.ts:74`, `commands/stop.ts:56-59`, `commands/status.ts:86-89`, `db/migrate.ts:38-46`. Risks adds a "singleton-relaxation sweep misses a call site" risk with a CI grep guardrail as mitigation. + +### Cl3. `resolveTarget` signature expansion not called out + +> The spec says routing will use `spawnedByArchitectId` but the current `resolveTarget(to, workspace)` has no sender context parameter. The spec should acknowledge that the resolver needs sender identity passed in. + +**Status**: Addressed. Duplicate of C4 / G3; see those responses. + +### Cl4. Architect-gone edge case unspecified + +> What happens when a builder's spawning architect has disconnected/exited but the builder is still running? Differs from the legacy-builder case (no ID) — this is a builder with a valid `spawnedByArchitectId` pointing to an architect that's no longer present. + +**Status**: Addressed. + +**Change**: Scope item 6 now distinguishes the two cases. Both fall back to `"main"` if present; both fail with distinct error messages if `"main"` is absent. The error text differs between the two cases (legacy-builder vs. architect-gone) and is asserted by test (Test Scenarios 4–7). + +### Cl5. Architect reconnect (terminalId changes) + +> If A reconnects with a *different* terminal ID (which happens on shellper reconnect), the routing must resolve by `architectId` → current terminal ID, not by a stale terminal ID. + +**Status**: Addressed. + +**Change**: Scope item 1 now explicitly states `architectId` is stable across reconnects; routing keys on `architectId`, not `terminalId`. Solution Approach (layer 1) repeats this. Test Scenarios #8 ("Architect reconnect") covers it: a builder spawned from `sibling` keeps reaching `sibling` after `sibling`'s terminal is killed and recreated. + +### Cl6. Workspace stop with multiple architects + +> `tower-routes.ts:1882-1884` ... workspace teardown iterates the architect as a single value. This needs to become a loop. + +**Status**: Addressed. + +**Change**: Cited in Scope item 2 as part of the call-site enumeration. Test Scenarios #12 ("Workspace stop with multiple architects") added to cover the iterated teardown. + +### Cl7. Annotations parent_id (forward-looking) + +Claude flagged that the `annotations` table's `parent_type CHECK(parent_type IN ('architect', 'builder', 'util'))` may eventually need `parent_id` populated for architect-owned annotations. + +**Status**: Acknowledged; out of scope for v1. + +**Rationale**: Architect-scoped annotations are not part of the message-routing problem this spec addresses. They are adjacent to the multi-architect identity feature but separable. If issue #2 (per-architect identity in spawn + status) lands, that's a more natural time to update annotation parentage. For v1, no annotation behavior changes. + +--- + +## Items I did NOT change (and why) + +- **Open Question on `architectId` mechanism** (env var vs. config vs. API parameter): kept open. The spec commits to *some* mechanism existing, with `"main"` as the default; the choice is a plan-phase decision. None of the reviewers pushed back on this deferral. +- **No explicit `--architect` CLI flags in `afx spawn` / `afx status`**: kept out of scope per the architect's explicit instruction at spawn time. All three reviewers respected this scope and did not request it. +- **No `THREAD.md` template or `codev thread` commands**: out of scope, will be follow-up issue. No reviewer requested its inclusion. + +--- + +## Summary + +Codex and Gemini both flagged REQUEST_CHANGES with substantive technical issues; Claude flagged COMMENT with the same caliber of feedback. All actionable items have been addressed in the updated spec. The spec is now firmly grounded in the actual codebase (verified call sites, accurate schema, correct routing pipeline), and the v1 product decisions that were previously deferred (broadcast syntax, dashboard shape, fallback semantics) are now pinned. + +I believe the spec is ready for re-review. diff --git a/codev/projects/755-multi-architect-support-per-ar/status.yaml b/codev/projects/755-multi-architect-support-per-ar/status.yaml new file mode 100644 index 000000000..8086e6401 --- /dev/null +++ b/codev/projects/755-multi-architect-support-per-ar/status.yaml @@ -0,0 +1,81 @@ +id: '755' +title: multi-architect-support-per-ar +protocol: spir +phase: review +plan_phases: + - id: phase_1 + title: Storage and Tower data-model relaxation + status: complete + - id: phase_2 + title: Naming CLI and spawn-time identity capture + status: complete + - id: phase_3 + title: Affinity-aware routing + status: complete +current_plan_phase: null +gates: + spec-approval: + status: approved + requested_at: '2026-05-17T21:06:40.091Z' + approved_at: '2026-05-18T02:43:42.920Z' + plan-approval: + status: approved + requested_at: '2026-05-18T02:59:12.937Z' + approved_at: '2026-05-18T05:22:46.669Z' + pr: + status: pending + verify-approval: + status: pending +iteration: 1 +build_complete: true +history: + - iteration: 1 + plan_phase: phase_1 + build_output: '' + reviews: + - model: gemini + verdict: REQUEST_CHANGES + file: >- + /Users/mwk/Development/cluesmith/codev/.builders/spir-755/codev/projects/755-multi-architect-support-per-ar/755-phase_1-iter1-gemini.txt + - model: codex + verdict: REQUEST_CHANGES + file: >- + /Users/mwk/Development/cluesmith/codev/.builders/spir-755/codev/projects/755-multi-architect-support-per-ar/755-phase_1-iter1-codex.txt + - model: claude + verdict: APPROVE + file: >- + /Users/mwk/Development/cluesmith/codev/.builders/spir-755/codev/projects/755-multi-architect-support-per-ar/755-phase_1-iter1-claude.txt + - iteration: 1 + plan_phase: phase_2 + build_output: '' + reviews: + - model: gemini + verdict: REQUEST_CHANGES + file: >- + /Users/mwk/Development/cluesmith/codev/.builders/spir-755/codev/projects/755-multi-architect-support-per-ar/755-phase_2-iter1-gemini.txt + - model: codex + verdict: REQUEST_CHANGES + file: >- + /Users/mwk/Development/cluesmith/codev/.builders/spir-755/codev/projects/755-multi-architect-support-per-ar/755-phase_2-iter1-codex.txt + - model: claude + verdict: REQUEST_CHANGES + file: >- + /Users/mwk/Development/cluesmith/codev/.builders/spir-755/codev/projects/755-multi-architect-support-per-ar/755-phase_2-iter1-claude.txt + - iteration: 1 + plan_phase: phase_3 + build_output: '' + reviews: + - model: gemini + verdict: APPROVE + file: >- + /Users/mwk/Development/cluesmith/codev/.builders/spir-755/codev/projects/755-multi-architect-support-per-ar/755-phase_3-iter1-gemini.txt + - model: codex + verdict: REQUEST_CHANGES + file: >- + /Users/mwk/Development/cluesmith/codev/.builders/spir-755/codev/projects/755-multi-architect-support-per-ar/755-phase_3-iter1-codex.txt + - model: claude + verdict: APPROVE + file: >- + /Users/mwk/Development/cluesmith/codev/.builders/spir-755/codev/projects/755-multi-architect-support-per-ar/755-phase_3-iter1-claude.txt +started_at: '2026-05-17T20:51:15.851Z' +updated_at: '2026-05-18T06:48:04.127Z' diff --git a/codev/resources/arch.md b/codev/resources/arch.md index 503742a0a..28bc35f6b 100644 --- a/codev/resources/arch.md +++ b/codev/resources/arch.md @@ -542,8 +542,9 @@ This dual-source strategy (SQLite + live shellper processes) ensures sessions su | `GET` | `/health` | Health check (uptime, memory, active projects) | | `GET` | `/api/workspaces` | List all workspaces with status | | `GET` | `/api/workspaces/:enc/status` | Get workspace status (terminals, gates) | -| `POST` | `/api/workspaces/:enc/activate` | Activate workspace (creates architect terminal) | -| `POST` | `/api/workspaces/:enc/deactivate` | Deactivate workspace (kills all terminals) | +| `POST` | `/api/workspaces/:enc/activate` | Activate workspace (creates `main` architect terminal) | +| `POST` | `/api/workspaces/:enc/architects` | Register an additional named architect (Spec 755) | +| `POST` | `/api/workspaces/:enc/deactivate` | Deactivate workspace (kills all architect terminals + builders + shells) | | `GET` | `/api/status` | Legacy: Get all instances (backward compat) | | `POST` | `/api/launch` | Legacy: Launch instance (backward compat) | | `POST` | `/api/stop` | Stop instance by workspacePath | @@ -590,6 +591,36 @@ Clients may ignore unknown event types — older clients silently drop `builder- | `GET` | `/api/terminals/:id/output` | Get ring buffer output | | `WS` | `/ws/terminal/:id` | WebSocket terminal connection | +#### Multi-architect routing (Spec 755) + +A workspace can host more than one architect terminal.

The "sibling-architect" workflow that this spec set out to support — one human running two architect agents in the same workspace, each with its own builder pool — was implemented manually via copy-pasting messages between terminals. + +This PR ships v1 of multi-architect support: a workspace can now host an arbitrary number of named architect terminals; every builder records the name of the architect that spawned it; and `afx send architect` from a builder is routed to its own spawning architect, not to a shared singleton. The mechanism is opt-in for users via a new `afx workspace add-architect [--name ]` command. Existing single-architect workspaces see byte-for-byte identical behavior — the default architect is named `main`, every singleton-style API path preserves its old shape via a `main`-first shim. + +Scope was deliberately tight: routing-only. The other four feature asks from issue #755 (`--architect` filter on `afx status`, `THREAD.md` template, cross-thread visibility, thread-aware `consult`) are explicitly out-of-scope for v1 and are tracked as future work. + +## Spec Compliance + +All 13 success criteria from the spec are met.

While verifying, I discovered that `setArchitect` (and by extension the local `architect` table) was effectively orphaned: only tests called it. Phase 2 wired up both `launchInstance` (writes `main`) and `addArchitect` (writes the new name) to call into `state.ts`, which closes the pre-existing gap. This is slightly outside Phase 2's stated scope but fixes a latent inconsistency that Gemini's Phase 1 review hinted at and Codex's Phase 2 review caught explicitly. +- **Phase 1 — used existing readonly-Database pattern in `state.ts`, not in `tower-messages.ts`.** The plan suggested putting the per-workspace readonly DB handle directly in the resolver to avoid import cycles. The actual fix lives in `state.ts:lookupBuilderSpawningArchitect(builderId, workspacePath?)`, which uses the same readonly pattern as `servers/overview.ts`. The resolver imports it normally. This is cleaner — no `state.ts → tower-messages.ts` import existed to create a cycle in the first place — and keeps the DB logic in the module that owns the state model. +- **Phase 2 CLI shape — `afx workspace add-architect` vs. the spec's `afx architect --name`.** The architect's spec-review example was `afx architect --name `, but `commands/architect.ts` already exists and explicitly disclaims Tower involvement. Repurposing it would break the no-Tower contract for users who run `afx architect` outside any workspace. The architect approved the alternative shape at the plan-approval gate. + +## Phase Summary + +### Phase 1 — Storage and Tower data-model relaxation +- Type-level: `ArchitectState.name`, `Builder.spawnedByArchitect`, `WorkspaceTerminals.architects: Map`. +- Schema: v9 local migration rebuilds the `architect` table as `id TEXT PRIMARY KEY` (rekeys existing row to `main`); adds `builders.spawned_by_architect`. v13 global backfill sets `terminal_sessions.role_id = 'main'` for legacy architect rows. +- Sweep: ~12 singleton call sites updated across `tower-instances.ts`, `tower-routes.ts`, `tower-terminals.ts`, `tower-tunnel.ts`, `commands/stop.ts`, plus `state.ts` and `db/migrate.ts`. +- CI guardrail: `spec-755-guardrail.test.ts` fails the build if `entry.architect` (singular) reappears in production code. + +### Phase 2 — Naming CLI and spawn-time identity capture +- New `afx workspace add-architect [--name ]` CLI under the `workspace` noun; existing `afx architect` (local-only Claude session) intentionally unchanged. +- `addArchitect()` in `tower-instances.ts` mirrors `launchInstance`'s shellper-then-fallback structure but is parameterised on name + supports collision rejection. +- `CODEV_ARCHITECT_NAME` env var injected into every architect terminal at PTY-start time. +- `afx spawn` reads the env var at module load and persists `spawnedByArchitect` on every new builder row, including a `COALESCE` in the SQL `ON CONFLICT` clause to preserve the value across status-update re-upserts. + +### Phase 3 — Affinity-aware routing +- Widened `resolveTarget(target, fallbackWorkspace?, sender?)`. Sender plumbed from `handleSend()` (where it always arrived but was dropped before resolution). +- Single-architect fast path skips the state.db read entirely — guaranteed latency parity for solo-architect users. +- Three security rules with verbatim spec error messages: legacy-builder (`legacyBuilderErrorMessage`), architect-gone (`architectGoneErrorMessage`), address-spoofing (`addressSpoofingErrorMessage`). +- `architect:` addressing handled via a dedicated `resolveArchitectByName` helper that intercepts before `findWorkspaceByBasename` (the `project:agent` parser would otherwise treat `architect:sibling` as a cross-workspace address). + +## Architecture Updates + +See `## Architecture Updates Detail` below — added a new "Multi-architect routing" subsection to `codev/resources/arch.md` documenting the name-keyed `WorkspaceTerminals.architects` invariant, the `lookupBuilderSpawningArchitect` per-workspace readonly pattern, and the four-layer routing chain (CLI → handleSend → resolveTarget → architects map). The CI guardrail in `spec-755-guardrail.test.ts` is also referenced. + +## Lessons Learned Updates + +See `## Lessons Learned Updates Detail` below — added two entries to `codev/resources/lessons-learned.md`: +1. **Vestigial state**: `setArchitect` was orphaned for an unknown duration. The lesson is to run "is this called?" checks during the planning sweep when a feature touches a long-lived API, not only when the feature touches new code. +2. **Single-source-of-truth error messages**: exporting the three Spec 755 error strings as functions, imported by both producer and asserter, caught a verbatim-text drift between spec and implementation in iter-2 review. + +## Lessons Learned + +### What went well +- **Three sequential phases with clear seams.** Each phase committed independently, ended with a meaningful demo, and never required reverting earlier work to make the next phase land. Phase 1 ended with the migration + sweep in place; Phase 2 with named architects creatable but not yet routed; Phase 3 with the user-visible win. +- **Spec text as verbatim test assertions.** Exporting error messages as functions imported by both producer and asserter was a great forcing function: drift between spec and code shows up as a failing test, not a silent regression. +- **Multi-agent consultation caught real bugs every iteration.** Specifically: Codex's `architect:` parsing collision (Phase 3 iter-1), Gemini's per-workspace DB lookup bug (Phase 3 iter-1), Codex's empty-`--name` and missing local-state.db persistence (Phase 2 iter-1). Without consultation these would have either landed broken or been caught downstream at much higher cost. +- **CI guardrail tests are cheap insurance for sweep-style refactors.** The `entry.architect` (singular) grep test took 30 minutes to write and would catch any future re-introduction. The reverse — finding that a contributor accidentally reverted the singleton-relaxation in some edge path — would take hours. + +### Challenges encountered +- **Discovered orphaned production code.** `setArchitect` was called only from tests, meaning the local `state.db` `architect` table was effectively unused for an unknown duration. This wasn't a Phase 2 regression — it was pre-existing — but the iter-1 reviewers correctly insisted we wire it up rather than perpetuate the inconsistency. +- **`parseAddress` overload between `project:agent` and `architect:`.** The grammar is genuinely ambiguous: both forms use a colon. The fix is a special-case intercept in `resolveTarget` before `findWorkspaceByBasename` runs. Tests that bypassed this (calling `resolveTarget('sibling', ...)` directly) initially hid the bug — a good lesson in testing through the public CLI shape, not the internal resolver. +- **Migration version mismatch with plan.** The plan called for "v5" as the new migration, but the project's actual local DB was already at v8 and global at v12. Sequencing through the real version numbers (v9 local, v13 global) was a footnote, but it's a reminder that planning documents that reference specific numbers should be confirmed against current state before commit. + +### What would be done differently +- **Front-load the full call-site scan.** Phase 1's "singleton homes" enumeration was three places initially; reviewers found at least six more before commit. A more thorough grep + reading of all `entry.architect` / `.architect` / `WorkspaceTerminals` accesses *before* writing the spec would have caught these earlier and avoided two rounds of spec-iter rework. +- **Earlier per-workspace DB question.** The plan correctly noted Tower's multi-workspace nature, but the implementation forgot it in iter-1. A more explicit "what's the workspace context for this DB call?" review checklist would have caught it before consult. +- **Test the public address grammar, not the resolver internals.** The Phase 3 iter-1 tests called `resolveTarget('sibling', ...)` instead of `resolveTarget('architect:sibling', ...)`. Both work at the resolver level but only one reflects how the CLI actually invokes it. Lesson: test the wire format, not the internal data type. + +### Methodology improvements +- **Phase-iteration consult pattern is healthy.** The iter-1/iter-2 cadence per phase (3-way consult → rebuttal → commit → repeat if needed) caught real bugs that single-pass review would have missed. Continue. +- **Rebuttal documents are valuable artifacts.** Future readers can trace why each implementation choice was made and which reviewer flagged what. Keep these. +- **Plan-phase version numbers as placeholders.** If the plan references specific migration version numbers (`v5`, `v9`, etc.), the implementer should verify those against the current schema before committing — or the plan should refer to migrations by purpose ("the next available migration after the issue_number widening") rather than fixed numbers. + +## Technical debt + +- **No end-to-end Tower-process test for affinity routing.** Codex iter-2 review flagged this; the route layer, resolver layer, and DB lookup are each individually tested, but no test currently spawns a real Tower, registers two architects, and verifies an `/api/send` from a builder reaches the right architect via HTTP. Adding such a test cleanly is ~100 LOC of subprocess + workspace-setup work; documented as deferred in `755-phase_3-iter2-rebuttals.md`. The functional layers are deterministic, so a regression would surface in one of the existing tests, but the gap is real and worth filling in a follow-up PR. +- **`commands/stop.ts` legacy fallback's `state.architect?.terminalId` dependence on `loadState`.** Now that `setArchitect` is called by `launchInstance`, the legacy path is meaningful again — but the `state` it reads is the scalar shim, not the full multi-architect collection. `commands/stop.ts` separately iterates `getArchitects()` for the multi-architect cleanup. This is correct but the two code paths are easy to confuse; a future cleanup should pick one source of truth. +- **Exit handler duplication in `tower-instances.ts` `addArchitect`.** Two near-identical handlers for shellper and non-persistent paths.

The first architect started in a workspace is named `main` by default; subsequent architects are auto-numbered `architect-2`, `architect-3`, etc. unless the user specifies a name explicitly (e.g., via `afx architect --name `). `main` is just the default name of the first architect — there is no "first-class main" concept beyond defaults. + +## Current State + +### Architect singleton + +`WorkspaceTerminals` only holds room for one architect terminal per workspace: + +```ts +// packages/codev/src/agent-farm/servers/tower-types.ts:33-39 +export interface WorkspaceTerminals { + architect?: string; + builders: Map; + shells: Map; + fileTabs: Map; +} +``` + +The SQLite mirror enforces the same singleton at the data layer: + +```sql +-- packages/codev/src/agent-farm/db/schema.ts:18-26 +CREATE TABLE IF NOT EXISTS architect ( + id INTEGER PRIMARY KEY CHECK (id = 1), + pid INTEGER NOT NULL, ... + terminal_id TEXT +); +``` + +### Builder spawn metadata + +`Builder` records what kind of work the builder is doing, but **no field captures who spawned it**: + +```ts +// packages/codev/src/agent-farm/types.ts:7-19 +export interface Builder { + id: string; + name: string; + status: 'spawning' | 'implementing' | 'blocked' | 'pr' | 'complete'; + phase: string; + worktree: string; + branch: string; + type: BuilderType; + taskText?: string; + protocolName?: string; + issueNumber?: number | string; + terminalId?: string; +} +``` + +`afx spawn` (`packages/codev/src/agent-farm/commands/spawn.ts:439`) calls `upsertBuilder()` without any spawning-architect identifier. + +### Message resolution + +`afx send architect "..."` flows through: + +1. `commands/send.ts:183` — sender identity is detected from worktree path; defaults to `'architect'` when run from the main workspace. +2. `TowerClient.sendMessage()` POSTs to `/api/send` with a `from` field (`packages/core/src/tower-client.ts:310-346`). +3. `handleSend()` (`packages/codev/src/agent-farm/servers/tower-routes.ts:819-949`) extracts `from` from the request body but **drops it** before calling `resolveTarget(to, workspace)` (`tower-routes.ts:854`). `from` is only used downstream for *message formatting*, not for routing. +4. `resolveAgentInWorkspace` matches `'architect'` or `'arch'` and returns the single `entry.architect` terminal ID (`tower-messages.ts:191-200`). +5. Message is written directly to that terminal's PTY (with idle-aware buffering). + +There is **no fan-in stage** that could distinguish multiple architects, because there is only one architect terminal to deliver to — and the resolver currently has no access to sender identity even if there were. + +### How users work around it today + +- Per-thread markdown files at `codev/-thread.md` with active builder rosters, PR lists, pending decisions, and pickup checklists. +- Cross-architect coordination conventions enforced by discipline ("this thread does NOT approve sibling-thread's gates"). +- Mental triage on every `architect` ping ("is this mine?"). +- **Manual copy-paste** of builder messages from the main architect's terminal into the sibling architect's terminal — every single ping that conceptually belongs to the sibling has to be relayed by a human. This is the most visible day-to-day cost of the singleton design. + +These conventions work but are brittle and require discipline that doesn't scale. + +## Desired State + +A builder that was spawned by architect **A** should, when running `afx send architect "..."`, deliver the message **only to architect A's terminal**, not to any sibling architects sharing the workspace. + +Concretely: + +- A workspace can host **multiple architect terminals** simultaneously. +- Each architect terminal has a **name** — a stable identifying string. The name is the architect's identity; there is no separate internal "architectId" field. (Earlier drafts of this spec used `architectId` as a distinct identifier; the architect clarified that the human-readable name *is* the identifier. The spec uses `name` throughout from this point forward.) +- The first architect started in a workspace defaults to the name `main`. Subsequent architects auto-number to `architect-2`, `architect-3`, etc. Either can be overridden with an explicit flag (e.g., `afx architect --name `). +- Every builder spawned during architect A's session records `spawnedByArchitect: A` (the spawning architect's name) in its persisted state. +- `afx send architect "..."` from within a builder worktree resolves the destination using the builder's recorded `spawnedByArchitect` — message goes to that architect's terminal, not to any sibling. +- Existing single-architect workspaces continue to work with **zero behavior change** — the singleton's name defaults to `main`, and builders persisted before this feature route to `main`. + +## Scope + +### In scope (v1) + +1. **Architect name** — a stable string per architect terminal. The first architect started in a workspace defaults to `main`; subsequent architects auto-number (`architect-2`, `architect-3`, …) unless the user supplies an explicit name (e.g., `afx architect --name `). The name is the architect's identity — no separate internal ID. The name is stable across reconnects (shellper restart); only the `terminalId` may change. Routing keys on the name, not the `terminalId`. Allowed character set: `[a-z][a-z0-9-]*`, max length 64. +2. **CLI surface for naming** — v1 introduces enough CLI to start a second (or N-th) named architect terminal in a workspace, and to make the first architect's default name (`main`) auditable. The exact subcommand shape is a plan-phase decision; the architect's example was `afx architect --name `. v1 does **not** add `--architect` filtering to `afx status` or any other UX polish from issue #2. +3. **Multiple architect terminals per workspace** — relax the in-memory and on-disk singletons to allow N architect terminals indexed by name. This touches **all of the following call sites** (the plan phase will enumerate any further occurrences): + - `WorkspaceTerminals.architect` (`tower-types.ts:35`) — change from `string | undefined` to a collection keyed by architect name. + - The local `architect` table in `state.db` (`db/schema.ts:18`) — drop `CHECK (id = 1)`; the new primary key is the architect name (`id TEXT PRIMARY KEY`). **No** `workspace_path` column is added — `state.db` is already per-workspace. (Previous draft of this spec was wrong on this point.) + - The `terminal_sessions` table in `global.db` (`db/schema.ts:94-112`) — for rows where `type = 'architect'`, write the architect's name into the existing `role_id` column. (Schema unchanged; the contract change is "`role_id` is no longer null for architect rows".) + - `resolveAgentInWorkspace` (`tower-messages.ts:177-200`) — generalize the architect match. + - The activation guard in `tower-instances.ts:354` (`if (!entry.architect)`) and the architect-create paths at `:416`, `:452`. + - Architect teardown/iteration sites: `tower-routes.ts:1411` (state response), `:1853-1855` (terminal kill), `:1882-1884` (workspace stop); `tower-instances.ts:529-532` (workspace stop); `tower-terminals.ts:289-290` (terminal cleanup), `:642` (terminal re-attach); `tower-tunnel.ts:74` (architect URL map); `commands/stop.ts:56-59` (CLI stop); `db/migrate.ts:38-46` (state migration); `commands/status.ts:86-89` (CLI status). The plan must visit each. +4. **Spawn-time capture** — `afx spawn` records `spawnedByArchitect` (the spawning architect's name) on the persisted `Builder` row. When `afx spawn` is run from inside a Tower-managed architect terminal, the spawning architect's name is detected automatically (e.g., from an env var Tower injects when starting the architect terminal); when run outside any architect terminal, it defaults to `main`. +5. **Routed `architect` resolution from builders** — the `from` field already arrives at `handleSend()` but is dropped before `resolveTarget()`. v1 plumbs sender identity into the resolution layer (either by widening `resolveTarget`'s signature to accept a sender, or by adding a dedicated builder-context resolution path one layer up). When the sender is a builder, `'architect'` resolves to the builder's recorded `spawnedByArchitect`. When the sender is not a builder (e.g., cron/task routing, manual `architect` sends from outside any builder worktree), `'architect'` resolves to the architect named `main` if present, falling back to the first registered architect if `main` is absent. +6. **Architect-gone semantics** — if a builder's `spawnedByArchitect` points to an architect that is no longer registered (e.g., that architect terminal was killed), `afx send architect` falls back to the architect named `main` if present; if `main` is absent, the send fails with a clear error message naming the missing architect and listing the registered ones. This is distinct from "legacy builder with no `spawnedByArchitect`," which has the same fallback rule but a different error message. +7. **Dashboard / `/api/state` shape** — v1 deliberately keeps the existing `state.architect` scalar shape in the `/api/state` response, populated with the architect named `main` (or the first registered architect if `main` is absent). The dashboard and VSCode extension see a single architect tab, identical to today. Surfacing all architects in the UI is **out of scope** and will be picked up by issue #2 (per-architect identity in spawn + status). This is the explicit decision; the plan must not change it without an amendment to this spec. +8. **Backward compatibility** — workspaces with one architect (no opt-in needed) behave identically to today. Builders persisted before this feature lands (no `spawnedByArchitect` on the row) route to the default `main` architect. + +### Explicitly NOT in scope + +- **Broadcast / fan-out address.** Earlier drafts of this spec proposed a plural `architects` broadcast address. The architect rejected this as not required for the production workflow that motivated this feature. v1 ships **only** point-to-point routing from a builder to its spawning architect. If a future need for broadcast emerges, it can be added cleanly on top of the named-architect resolution (e.g., a follow-up issue introduces `architects` as a fan-out target). + +### Out of scope (deferred to follow-up issues) + +The full GitHub issue lists five feature asks. **Only #1 (builder-to-architect message routing) is in scope for v1.** The remaining four are tracked as separate follow-up issues to be filed after this lands: + +- **Per-architect identity in spawn + status CLI flags** (#2 in issue): explicit `--architect ` on `afx spawn`, `--architect` filter on `afx status`. v1 ships the underlying identity field but does not add CLI flags; identity is detected from execution context only. +- **First-class `THREAD.md` template + lifecycle** (#3 in issue): `codev thread new|list|archive` commands. Pure convention layer, independent of routing. +- **Cross-thread visibility** (#4 in issue): `codev thread show ` to read sibling state. Independent of routing. +- **Thread-aware `consult`** (#5 in issue): `consult --thread ` or auto-detection from a `.thread` file. Independent of routing. + +These five items compose cleanly once #1 lands. Each will be filed as its own follow-up issue with its own protocol after this PR merges. + +## Stakeholders + +- **Primary**: External Codev consumers running the sibling-architect pattern on large projects (the reporter of #755 plus any future users adopting the pattern). +- **Secondary**: Solo-architect users — must see **zero behavior change**. +- **Technical Team**: Codev maintainers (Tower routing, agent-farm commands, state schema). +- **Business Owners**: M Waleed Kadous (architect role for Codev). + +## Success Criteria + +- [ ] Two architect terminals can run simultaneously in one workspace (Tower accepts multiple architect registrations with distinct names). +- [ ] The first architect started in a workspace gets the name `main` by default. A second architect started without an explicit name gets `architect-2`; a third gets `architect-3`; and so on. An explicit name supplied via the CLI overrides the default. +- [ ] A builder spawned from architect A's terminal records `spawnedByArchitect: "A"` on its persisted row (or the default `main` when `afx spawn` runs outside any architect terminal). +- [ ] `afx send architect "..."` from inside a builder's worktree routes to **only** the architect that spawned that builder; sibling architects do not receive the message. +- [ ] Existing single-architect workspaces show **no behavior change**: `afx send architect` routes to the lone architect just as it does today, and the `/api/state` response shape is unchanged (scalar `architect`). +- [ ] Builders persisted **before** this feature (no `spawnedByArchitect` field) route to the architect named `main` if present; otherwise fail with a clear error listing the registered architects. The error message is asserted by test. +- [ ] Builders whose `spawnedByArchitect` points to an architect that is no longer registered fall back to `main` if present; otherwise fail with a distinct clear error. Error message is asserted by test. +- [ ] An architect terminal that reconnects after a crash (new `terminalId`, same name) continues to receive its builders' messages without any builder-side change. +- [ ] Non-builder `architect`-targeted sends (e.g., `afx cron`-originated messages, `afx send architect` from the workspace root) continue to route to `main` (or the first registered architect if `main` is absent) — they are **not** affinity-aware. +- [ ] A builder address-spoofing attempt (a builder writing `architect:` where that name is not its own `spawnedByArchitect`) is rejected with a clear error. Asserted by test. +- [ ] All existing tests pass; new tests cover the routing matrix (single, multi-with-match, legacy-builder-fallback, architect-gone, architect-reconnect, address-spoofing-rejection, auto-numbering of default names). +- [ ] No performance regression in message delivery (single-architect workspaces should see identical latency). +- [ ] State-migration test: a `state.db` produced by the previous schema (singleton architect row, `id = 1`, `terminal_sessions.role_id = NULL` for the architect session) survives the schema upgrade. The architect row is preserved with its `terminal_id`, and the matching `terminal_sessions.role_id` is backfilled to `main`. + +## Constraints + +### Technical constraints + +- **Backward compatibility is non-negotiable.** Single-architect workspaces and pre-existing builder state rows must behave exactly as before. This is the single largest design constraint. +- The architect singleton is enforced in **many places**, not just three. The Scope section enumerates them. They must be relaxed in lockstep — leaving any one of them stuck on the singleton assumption will produce subtle data-loss or routing bugs. +- Tower's in-memory `WorkspaceTerminals` is the source of truth for live routing; the local `state.db` schema must be a faithful mirror for crash recovery, and the global `terminal_sessions` table must encode the architect's name in `role_id` so that crash recovery can restore the multi-architect topology. +- The local `architect` table needs a schema migration: drop `CHECK (id = 1)` and change `id` to `TEXT PRIMARY KEY` storing the architect's name. **No `workspace_path` column is added** — `state.db` is per-workspace already, so workspace scoping is implicit. (Prior consultation flagged that an earlier draft proposed a `workspace_path` column; that was incorrect against the actual schema.) +- The global `terminal_sessions` table does not need a schema change; the migration is a data-shape contract change. Existing rows with `type = 'architect'` and `role_id = NULL` must be backfilled to `role_id = 'main'` so that crash recovery routes legacy single-architect workspaces correctly. +- Architect names follow `[a-z][a-z0-9-]*`, max length 64 chars. The reserved default name is `main`. Auto-numbered defaults follow `architect-` where `` is the smallest integer ≥ 2 not currently in use in the workspace. +- `resolveTarget`'s current signature is `(target, fallbackWorkspace?)` and has no sender parameter. v1 expands the resolution layer to accept the sender's identity. The choice between widening `resolveTarget` itself or adding a sibling builder-context resolver is a plan-phase decision; the spec only requires that sender identity reach the resolution code path. + +### Business constraints + +- This is upstream work for an external Codev consumer with the sibling-architect pattern in daily production use. **Time-to-merge matters** — keep scope tight. +- Solo-architect users must never have to know this feature exists. No new mandatory CLI flags, no new mandatory config keys. + +## Assumptions + +- The reporter's workflow uses **two** architect terminals; the design must not collapse on N=2 but does not need to optimize for N=20. +- Architects are launched as Tower terminals (via `afx workspace start` or equivalent); we are not adding a way to register a "remote" or "headless" architect. +- Builder-originated `afx send architect` is the affinity-aware path. Non-builder code paths that target `architect` (e.g., cron-originated messages routed in `tower-cron.ts`, or `afx send architect` invoked from outside any builder worktree) keep the existing "route to the singleton (now `main`)" semantics. Builders cannot be affinity-aware about non-builder senders, so this is the natural fallback. +- The user is willing to add a CLI surface (the architect's example: `afx architect --name `) to start additional named architects. The exact subcommand shape is a plan-phase decision. + +## Solution Approach + +The mechanism splits naturally into three layers, mirroring how identity flows through the system: + +1. **Naming at registration.** When an architect terminal is created, Tower assigns it a name: either the explicit name the user supplied (e.g., `afx architect --name `) or the next available default (`main` for the first, `architect-` for subsequent). The same name survives reconnects — if the architect terminal crashes and shellper restarts it, the new `terminalId` is associated with the same name, and builders' messages keep routing correctly with no builder-side change. +2. **Identity at spawn.** When `afx spawn` creates a builder, it detects the spawning architect's name from execution context (an env var Tower injects when starting the architect terminal is the natural mechanism; plan-phase to confirm) and persists it on the builder row as `spawnedByArchitect`. When run outside any architect terminal, the default `main` is used. +3. **Routing at send.** The `from` field already arrives at `handleSend()` from the request body. v1 plumbs that `from` into the resolution layer so that when the sender is a builder and the target is `architect`, the resolver looks up the builder's `spawnedByArchitect` and returns the matching architect terminal — not the generic first-architect. For non-builder senders, the resolver returns the architect named `main` (or the first registered if `main` is absent). + +The plan phase will pin down: the exact CLI shape for naming additional architects (`afx architect --name ` is the architect's example, but plan-phase to confirm), the env-var contract that conveys the spawning architect's name into `afx spawn`, the signature change for the resolution layer, and the per-file edit list for the singleton-relaxation sweep. + +## Open Questions + +### Critical (blocks progress) + +*None remaining.* All previously-critical questions resolved during architect review (see below). + +### Important (affects design) + +- [ ] **Should the architect's name be visible in `afx status`?** Filtering is out of scope for v1, but operators may still want to see "which architect owns which builder." Plan phase to decide whether to add a non-filterable display column now, or defer entirely to issue #2. +- [ ] **Exact CLI shape for naming additional architects.** Architect's example was `afx architect --name `. Plan phase to confirm: is `afx architect` a new noun subcommand (with future room for `afx architect list`, `afx architect kill`, etc.), or a flag on an existing command (e.g., `afx workspace add-architect --name `)? The spec commits to the *capability*, not the surface. +- [ ] **Mechanism for conveying the spawning architect's name into `afx spawn`.** The natural choice is an env var (e.g., `CODEV_ARCHITECT_NAME`) injected by Tower into the architect terminal's shell. Plan phase to confirm and pick the exact var name. + +### Resolved (during architect review of iter-1) + +- ~~**Whether `architectId` is a separate field from the architect's display name.**~~ Decided: no — the name *is* the identity. Spec renamed `architectId` → architect name throughout. +- ~~**Naming defaults for new architects.**~~ Decided: first = `main`; subsequent auto-numbered (`architect-2`, `architect-3`, …); explicit override via CLI flag. +- ~~**Should v1 ship a broadcast address?**~~ Decided: no. The real workflow doesn't need it. Builders address `architect` (their own spawner) only. If a future need emerges, broadcast can be added cleanly on top of named-architect routing. +- ~~**How does an architect terminal declare its identity?**~~ Decided: via the CLI surface that starts the architect terminal (architect's example: `afx architect --name `). Plan phase fills in the exact subcommand shape. + +### Resolved (during consultation iteration 1) + +- ~~**Migration shape for the `architect` table.**~~ Decided: drop `CHECK (id = 1)`, change `id` to `TEXT PRIMARY KEY`. No `workspace_path` column; `state.db` is per-workspace. +- ~~**Should the dashboard show all architects in v1?**~~ Decided: no. `/api/state` shape is unchanged; the dashboard sees the `main` architect (or first registered). Multi-architect UI deferred to issue #2. +- ~~**What happens to non-builder `architect` sends (cron, manual)?**~~ Decided: they route to `main` (or first registered if `main` is absent), unchanged from today's effective behavior. +- ~~**What happens when a builder's spawning architect is gone?**~~ Decided: fall back to `main` if present; otherwise fail with a clear error listing registered architects. +- ~~**What happens on architect reconnect (terminalId changes)?**~~ Decided: routing keys on the architect's name, not on `terminalId`. Reconnect is transparent to builders. + +### Nice-to-know (optimization) + +- [ ] **Should sibling architects see metadata about other architects' builders (read-only)?** Adjacent to issue #4 (cross-thread visibility) which is explicitly deferred. Out of scope for v1. + +## Performance Requirements + +- **Routing overhead**: a single-architect `afx send architect` must add no measurable latency vs. today (single map lookup → single PTY write). +- **Storage**: per-builder `spawnedByArchitect` is a short string, persisted once at spawn. Negligible. +- **No new background processes, polling loops, or watchers.** All routing is on-demand at message-send time. + +## Security Considerations + +- **Cross-architect leakage**: a misrouted message could expose builder activity to a sibling architect who shouldn't see it. Three rules guarantee no leak across architects: + 1. **Legacy builder (no `spawnedByArchitect`)** → route to `main`; if `main` is absent, fail with error `"legacy builder has no spawning-architect identity and no 'main' architect is registered (registered: )"`. Asserted by test. + 2. **Architect-gone (`spawnedByArchitect` points to a no-longer-registered architect)** → route to `main`; if `main` is absent, fail with error `"builder was spawned by architect , which is no longer registered, and no 'main' architect is registered (registered: )"`. Asserted by test. + 3. **Cross-architect addressing rejected**: a builder cannot bypass routing by writing `architect:` as the target. The send rejects with `"builder may only address its own spawning architect"`. Asserted by test. +- No new auth surfaces, no new credentials, no new tokens. + +## Test Scenarios + +### Functional + +1. **Single-architect baseline (regression).** One architect (`main`) + one builder. `afx send architect "hi"` from builder reaches `main`. Identical to current behavior. `/api/state` response shape is unchanged. +2. **Two architects, scoped routing.** Architects `main` and `sibling`. Builder spawned from `main`. `afx send architect "hi"` reaches only `main`'s terminal, never `sibling`'s. +3. **Auto-numbered second architect.** Starting a second architect with no explicit name yields `architect-2`. Starting a third yields `architect-3`. Skipping `architect-2` (start, kill, restart) does not reuse the gap; `architect-3` is still next. (Plan phase decides whether to reuse gaps; spec only requires the smallest-unused-integer behavior described in Constraints.) +4. **Explicit name override.** Starting an architect with an explicit name (e.g., `afx architect --name sibling`) yields the supplied name. Re-using an already-registered name in the same workspace is rejected with a clear error. +5. **Legacy builder fallback (`main` present).** Builder row in DB has no `spawnedByArchitect`. `afx send architect` from that builder reaches `main`. +6. **Legacy builder fallback (`main` absent).** Same row, but no architect named `main` is registered. Send fails with the legacy-builder error message; the error text is asserted verbatim. +7. **Architect-gone (`main` present).** Builder has `spawnedByArchitect: "sibling"` but `sibling` is no longer registered. `main` is registered. Send reaches `main`. +8. **Architect-gone (`main` absent).** Same row, no `main` either. Send fails with the architect-gone error message; the error text is asserted verbatim, including the missing architect name and the list of registered architects. +9. **Architect reconnect.** Architect `sibling` is killed and recreated (new `terminalId`, same name). The builder spawned from `sibling` sends `afx send architect`; the message reaches the new terminal without any builder-side change. +10. **Spawning-architect detection.** `afx spawn` run from inside `main`'s architect terminal records `spawnedByArchitect: "main"`. Run from `sibling`'s architect terminal records `spawnedByArchitect: "sibling"`. Run outside any architect terminal defaults to `"main"`. +11. **Address-spoofing rejection.** A builder spawned by `main` tries to address `architect:sibling`. Rejected; error text asserted verbatim. +12. **Non-builder architect-target sends.** `afx send architect "hi"` invoked from the workspace root (not inside any builder worktree), in a multi-architect workspace, reaches `main`. Cron-originated architect messages route the same way. +13. **Workspace stop with multiple architects.** Workspace stop tears down **all** registered architect terminals, not just the first. + +### Non-functional + +1. **Latency parity.** Microbenchmark `afx send architect` in a single-architect workspace before and after the change. No statistically significant difference. +2. **Migration safety — local `state.db`.** Migration that drops `CHECK (id = 1)` and changes the `architect` table primary key to `TEXT` preserves the existing singleton row, rekeys its `id` to `main`, and preserves its `terminal_id` binding. +3. **Migration safety — global `terminal_sessions`.** Backfill that populates `role_id = 'main'` for existing rows where `type = 'architect' AND role_id IS NULL` runs idempotently and leaves non-architect rows untouched. + +## Dependencies + +- **Internal systems**: Tower instance manager, agent-farm CLI (`afx send`, `afx spawn`), SQLite state schema, `resolveTarget` logic, builder state model. +- **External services**: none. +- **Libraries / frameworks**: none new. + +## References + +- GitHub issue #755 (full multi-architect ask, all 5 features). + +**Singleton homes (must all be relaxed in lockstep):** +- `packages/codev/src/agent-farm/servers/tower-types.ts:33-39` — `WorkspaceTerminals` interface. +- `packages/codev/src/agent-farm/db/schema.ts:18-26` — local `architect` table. +- `packages/codev/src/agent-farm/db/schema.ts:94-112` — global `terminal_sessions` table (`role_id` contract). +- `packages/codev/src/agent-farm/servers/tower-messages.ts:177-200` — `resolveAgentInWorkspace`. +- `packages/codev/src/agent-farm/servers/tower-instances.ts:354,416,452,529-532` — activation guard, create paths, teardown. +- `packages/codev/src/agent-farm/servers/tower-routes.ts:1411-1418,1853-1855,1882-1884` — `/api/state` shape, terminal kill, workspace stop. +- `packages/codev/src/agent-farm/servers/tower-terminals.ts:289-290,642` — terminal cleanup and re-attach. +- `packages/codev/src/agent-farm/servers/tower-tunnel.ts:74` — architect URL map. +- `packages/codev/src/agent-farm/commands/stop.ts:56-59` — CLI stop. +- `packages/codev/src/agent-farm/commands/status.ts:86-89` — CLI status. +- `packages/codev/src/agent-farm/db/migrate.ts:38-46` — state migration. + +**Data model touch points:** +- `packages/codev/src/agent-farm/types.ts:7-19` — `Builder` interface (where `spawnedByArchitect` will live). +- `packages/codev/src/agent-farm/types.ts:37-41` — `ArchitectState` (needs `name`). +- `packages/codev/src/agent-farm/types.ts:43-48` — `DashboardState.architect` (scalar shape preserved in v1). +- `packages/codev/src/agent-farm/state.ts:75-111` — `upsertBuilder()` (records `spawnedByArchitect`). + +**Message flow:** +- `packages/codev/src/agent-farm/commands/send.ts:142-223` — afx send flow. +- `packages/codev/src/agent-farm/commands/spawn.ts:439` — `upsertBuilder()` call site. +- `packages/codev/src/agent-farm/servers/tower-routes.ts:819-949` — `handleSend`; `from` is dropped at line 854 before `resolveTarget`. +- `packages/core/src/tower-client.ts:310-346` — `TowerClient.sendMessage` (already propagates `from`). + +## Risks and Mitigation + +| Risk | Probability | Impact | Mitigation | +|------|-------------|--------|------------| +| Backward compat break for solo-architect users | Medium | High | Default architect name of `main`; legacy builder rows route to `main`; comprehensive regression test on the single-architect path. | +| Migration drops the singleton row on schema upgrade | Low | High | Two migration tests (local `state.db` + global `terminal_sessions` backfill); both asserted to preserve `terminal_id` and rekey the row's `id`/`role_id` to `main`. | +| Singleton-relaxation sweep misses a call site, leaking single-architect assumption | Medium | High | Enumerated list of known call sites in Scope item 3 + References.

Updated in Scope (item 2) and Constraints. +2. **More singleton homes than listed.** All three models flagged additional call sites beyond the three I'd enumerated. Codex named `DashboardState.architect`, `ArchitectState`, `InstanceStatus.architectUrl`, `loadState/setArchitect`. Gemini named `terminal_sessions.role_id` in `global.db`. Claude named the activation guard at `tower-instances.ts:354`, workspace stop at `tower-routes.ts:1882-1884`, `tower-tunnel.ts:74`. **Fix**: enumerated all known call sites in Scope (item 2) and References; framing changed from "three places" to "many places." +3. **`resolveTarget` has no sender context.** All three models pointed out that `from` is dropped at `handleSend` before reaching `resolveTarget`. **Fix**: Solution Approach now explicitly requires plumbing `from` into the resolution layer; Constraints calls out the signature change is a plan-phase decision (widen `resolveTarget` vs. add a sibling resolver). +4. **Broadcast syntax must avoid `project:agent` collision.** Codex and Gemini flagged that `architect:all` collides with the existing parser. **Fix**: pinned `architects` (plural, no colon) in Scope (item 5); marked the Open Question as resolved. + +### Codex-specific findings (addressed) + +- **Non-builder `architect` sends (cron/task).** Codex flagged that the assumption "no other code path uses `architect` as a target" is false (`tower-cron.ts` formats messages addressed to `architect`). **Fix**: Assumptions section rewritten; Scope (item 4) explicitly states non-builder senders keep the existing semantics. +- **Legacy fallback rule needed sharper success criteria.** **Fix**: Success Criteria now requires asserted error text for legacy-builder and architect-gone fallbacks. + +### Gemini-specific findings (addressed) + +- **`terminal_sessions` (global.db) is a fourth singleton home.** Currently `role_id` is `null` for architect rows. **Fix**: Scope (item 2) requires populating `role_id` with `architectId`; Success Criteria includes a global-DB migration test; Constraints notes the data-shape contract change. + +### Claude-specific findings (addressed) + +- **Dashboard / `/api/state` shape change.** Claude noted that changing `state.architect` from scalar to a collection would break the dashboard and VSCode extension. **Fix**: Scope (item 7) explicitly decides to keep `/api/state` scalar in v1, populated with `main` (or first); multi-architect UI deferred to issue #2. +- **Activation guard at `tower-instances.ts:354`.** **Fix**: included in the singleton-home enumeration in Scope (item 2). +- **Architect-gone vs. legacy builder edge case.** **Fix**: distinguished in Scope (item 6) and Security Considerations; separate test scenarios and separate error messages. +- **Architect reconnect (terminalId changes).** **Fix**: Scope (item 1) and Solution Approach (layer 1) explicitly state routing keys on `architectId`, not `terminalId`; test scenario added. + +### Persisted consultation outputs + +- `codev/projects/755-multi-architect-support-per-ar/755-specify-iter1-codex.txt` +- `codev/projects/755-multi-architect-support-per-ar/755-specify-iter1-gemini.txt` +- `codev/projects/755-multi-architect-support-per-ar/755-specify-iter1-claude.txt` +- `codev/projects/755-multi-architect-support-per-ar/755-specify-iter1-rebuttals.md` + +### Architect review (iteration 2) — 2026-05-18 + +The architect (M Waleed Kadous) reviewed the spec and left five inline comments. All five were addressed in this iteration: + +1. **Problem statement accuracy.** Today, only the singleton architect terminal receives a builder's message — a sibling architect agent isn't a Tower-registered architect at all, so it doesn't get the message directly. The original draft incorrectly said "both" architects see it. **Fix**: Problem Statement rewritten to describe the singleton's actual behavior plus the human's manual copy-paste workaround. +2. **Naming policy.** The architect specified concrete defaults: first architect = `main`; subsequent = auto-numbered (`architect-2`, `architect-3`, …); explicit override via a CLI flag (architect's example: `afx architect --name `). **Fix**: pinned in Scope item 1, with character-set/length rules in Constraints, and test scenarios for auto-numbering + explicit name + collision rejection. +3. **Workaround reality.** The architect literally copy-pastes messages from main's terminal to sibling's. **Fix**: added explicitly to "How users work around it today" as the most visible day-to-day cost. +4. **`architectId` is the same as the name.** **Fix**: renamed throughout. Builder field is now `spawnedByArchitect` (the architect's name); there is no separate ID. +5. **Broadcast is not required.** **Fix**: dropped the `architects` broadcast address from v1 scope entirely. Added explicit "NOT in scope" subsection. Removed associated tests, success criteria, and security carve-outs. Left a forward-looking note that broadcast can be added cleanly on top of named-architect routing if a future need emerges. + +## Approval + +- [ ] Architect review (M Waleed Kadous) +- [ ] Multi-agent consultation complete (Gemini, Codex, Claude) +- [ ] Spec-approval gate (porch) + +## Notes + +The architect's spawn-time directive was unambiguous: scope to feature #1 only. Items #2-5 are intentionally left as follow-up issues, even though some (especially #2, per-architect identity in spawn CLI flags) compose so directly with #1 that they'd be a small additional lift. The discipline of keeping v1 tight matters more than the incremental polish, and the spec keeps that line firmly. diff --git a/packages/codev/src/agent-farm/__tests__/db.test.ts b/packages/codev/src/agent-farm/__tests__/db.test.ts index c4daac2ae..79dcf13ad 100644 --- a/packages/codev/src/agent-farm/__tests__/db.test.ts +++ b/packages/codev/src/agent-farm/__tests__/db.test.ts @@ -49,18 +49,27 @@ describe('Database Schema', () => { expect(tableNames).toContain('annotations'); }); - it('should enforce architect singleton constraint', () => { - // Insert first architect + it('should allow multiple named architects (Spec 755 — singleton lifted)', () => { db.prepare(` INSERT INTO architect (id, pid, port, cmd, started_at) - VALUES (1, 1234, 4201, 'claude', datetime('now')) + VALUES ('main', 1234, 4201, 'claude', datetime('now')) `).run(); - // Attempting to insert a second architect with different id should fail + // A second named architect must succeed — the v9 migration dropped the + // singleton CHECK constraint. + db.prepare(` + INSERT INTO architect (id, pid, port, cmd, started_at) + VALUES ('sibling', 5678, 4201, 'claude', datetime('now')) + `).run(); + + const count = db.prepare('SELECT COUNT(*) as count FROM architect').get() as { count: number }; + expect(count.count).toBe(2); + + // Names are unique (PRIMARY KEY). expect(() => { db.prepare(` INSERT INTO architect (id, pid, port, cmd, started_at) - VALUES (2, 5678, 4201, 'claude', datetime('now')) + VALUES ('main', 9999, 4201, 'claude', datetime('now')) `).run(); }).toThrow(); }); diff --git a/packages/codev/src/agent-farm/__tests__/migrate.test.ts b/packages/codev/src/agent-farm/__tests__/migrate.test.ts index de1bd4beb..1c3031fa1 100644 --- a/packages/codev/src/agent-farm/__tests__/migrate.test.ts +++ b/packages/codev/src/agent-farm/__tests__/migrate.test.ts @@ -55,7 +55,8 @@ describe('Migration', () => { migrateLocalFromJson(db, jsonPath); - const architect = db.prepare('SELECT * FROM architect WHERE id = 1').get() as any; + // Spec 755: legacy singleton row migrates to architect named 'main' + const architect = db.prepare("SELECT * FROM architect WHERE id = 'main'").get() as any; expect(architect.pid).toBe(1234); expect(architect.port).toBe(4201); expect(architect.cmd).toBe('claude --dangerously-skip-permissions'); diff --git a/packages/codev/src/agent-farm/__tests__/spec-755-guardrail.test.ts b/packages/codev/src/agent-farm/__tests__/spec-755-guardrail.test.ts new file mode 100644 index 000000000..d5c05c0a3 --- /dev/null +++ b/packages/codev/src/agent-farm/__tests__/spec-755-guardrail.test.ts @@ -0,0 +1,82 @@ +/** + * Spec 755 — CI guardrail. + * + * Fails if any production source file uses the legacy singular accessor + * `entry.architect` or `entry.architect =`.
