+## Mos Runtime Portability Workstream (MOS-PORT)
+
+### Problem and Objective
+
+Mos is currently identified partly by a harness-native session and communication process. Replacement/rebinding exists, but no gateway-enforced logical identity or fencing prevents a stale harness from continuing to reply or execute effects after takeover.
+
+The objective is to make Mos a server-derived logical Mosaic identity whose authority can move safely among runtime connectors. The gateway owns identity, lease, policy, and audit; harnesses remain replaceable adapters.
+
+### M1 Requirements
+
+1. `MOS-PORT-ID-001`: Define a normalized logical-agent identity independent of Claude Code, Pi, Codex, tmux, Matrix, and provider-native session IDs.
+2. `MOS-PORT-LEASE-001`: Persist one exclusive connector lease per tenant/logical-agent/binding with CAS acquisition, monotonic fencing epoch, TTL, heartbeat, explicit release, and takeover.
+3. `MOS-PORT-FENCE-001`: Bind every connector dispatch/execution grant to the current server-derived tenant, logical identity, binding, connector, scopes, expiry, and lease epoch.
+4. `MOS-PORT-FENCE-002`: Reject and audit stale, expired, forged, cross-tenant, cross-binding, and unauthorized grants before connector, channel, provider, or tool side effects.
+5. `MOS-PORT-OBS-001`: Emit credential-safe correlation/audit events for lease acquire, renew, takeover, reject, release, and expiry.
+6. `MOS-PORT-ARCH-001`: Runtime/provider adapters consume normalized lease context without adding harness-native schemas to Mosaic core.
+
+### M1 Acceptance Criteria
+
+1. `AC-MOS-PORT-01`: Two contenders for one binding cannot simultaneously hold current authority under concurrency.
+2. `AC-MOS-PORT-02`: Successful takeover increments the fencing epoch and every operation from the old epoch fails closed before side effects.
+3. `AC-MOS-PORT-03`: Gateway/database restart preserves lease and epoch state; expired leases can be recovered only through the authorized takeover path.
+4. `AC-MOS-PORT-04`: Cross-tenant, cross-agent, cross-binding, forged, and expired lease/grant cases are denied and audited.
+5. `AC-MOS-PORT-05`: Unit, migration, repository close/reopen, concurrency, abuse, gateway integration, independent security review, CI, and documentation gates pass.
+
+### Deferred to Later #754 Milestones
+
+Canonical checkpoint/handoff payloads, exactly-once connector receipts, concrete Claude/Pi/Codex adapters, channel cutover, and full cross-harness failover/rollback E2E are explicitly out of M1 scope.

+# Mos Runtime Portability M1 — Logical Identity and Fencing
+
+## Boundary
+
+M1 separates the logical Mosaic agent from any Claude, Pi, Codex, tmux, Matrix, or provider-native session. The normalized identity is:
+
+```text
+(tenant_id, logical_agent_id, binding_id)
+```
+
+`logical_agent_id` is a server-owned stable identifier. A connector is a replaceable holder of a lease for one binding; it is not the agent identity.
+
+## Durable lease model
+
+PostgreSQL table `logical_agent_connector_leases` has one unique row per identity/binding tuple. The current row records:
+
+- an opaque lease UUID;
+- connector ID and normalized allowed scopes;
+- a positive decimal fencing epoch stored as PostgreSQL `bigint`;
+- acquired, heartbeat, expiry, release, and update timestamps.
+
+Initial acquisition is insert-only. An existing active row causes `lease_held`. An expired or released row causes `takeover_required`; ordinary acquisition cannot recover it. Authorized takeover uses compare-and-swap against the expected epoch, rotates the lease UUID, and increments the epoch atomically. Heartbeat and release match the full identity, binding, connector, lease UUID, and epoch.
+
+The companion `connector_lease_audit_log` is append-only metadata. It stores lifecycle event, outcome/reason, identity/binding/connector, epoch, correlation ID, and timestamp. It deliberately excludes scopes, grant objects, payloads, approval references, tokens, and credentials.
+
+## Execution grants
+
+`ConnectorLeaseCoordinator` issues a short-lived internal grant only after rereading the durable current lease. Defense-in-depth caps leases at 5 minutes and grants at 30 seconds by default; constructor options may tighten these limits. A grant is bound to tenant, logical agent, binding, connector, lease UUID, scope subset, expiry, and epoch.
+
+Validation occurs immediately before adapter invocation and rereads PostgreSQL. The adapter receives only `ConnectorExecutionContext`; harness-native schemas remain behind the adapter. Validation denies:
+
+- grants not minted by the current gateway process (including cloned/forged objects);
+- expired grants or leases;
+- released leases;
+- stale epochs or replaced connector/lease UUIDs;
+- missing/cross-tenant/cross-agent/cross-binding leases;
+- scopes not authorized by both grant and current lease.
+
+A gateway restart intentionally invalidates process-local grants. The durable lease and epoch survive, and a fresh grant may be issued only after current-lease and gateway-policy validation.
+
+## Concurrency and side-effect rule
+
+The database CAS determines the sole current holder. A successful takeover makes every old-epoch validation fail. Connector adapters must consume and propagate the normalized lease epoch/context so downstream effect boundaries can also fence races that occur after gateway validation.
+
+M1 does not provide exactly-once receipts or a side-effect journal. Those remain later #754 work; callers must not infer exactly-once delivery from lease fencing.
+
+## Extension boundary
+
+`ConnectorLeaseService` is the gateway-owned policy surface. Every policy decision receives the normalized requested scopes and TTL (or explicit `null` where no TTL applies), so a concrete policy can enforce least privilege and duration limits. Its production default policy denies every lease/grant operation until a server-configured connector policy is supplied. No M1 HTTP endpoint accepts caller-controlled tenant or logical identity, and no concrete Claude/Pi/Codex adapter or channel cutover is included.

+# Mos Connector Lease Operations — M1
+
+## Operational status
+
+M1 installs the durable schema and gateway policy/adapter boundary. It does **not** activate a connector, expose a lease administration endpoint, or cut over a channel. The default gateway connector-lease policy is deny-all until a later work package supplies an authorized server-side policy and concrete adapter.
+
+## Events to monitor
+
+Use correlation IDs to follow `connector_lease_audit_log` events:
+
+| Event      | Meaning                                                               |
+| ---------- | --------------------------------------------------------------------- |
+| `acquire`  | First holder inserted for an unused binding                           |
+| `renew`    | Current holder heartbeat extended the TTL                             |
+| `takeover` | Authorized CAS replaced the holder and incremented epoch              |
+| `release`  | Current holder explicitly relinquished authority                      |
+| `expiry`   | An expired current lease was observed                                 |
+| `reject`   | Policy, CAS, expiry, scope, or fencing validation denied an operation |
+
+Audit data is metadata-only. Raw grant objects, connector payloads, scopes, tokens, approval references, and credentials must never be added to audit output.
+
+## Incident checks
+
+For suspected duplicate/stale connector effects:
+
+1. Correlate the attempted operation with its `reject`, `takeover`, or `expiry` event.
+2. Compare the current row's connector ID, lease UUID, epoch, expiry, and release time with the adapter's normalized execution context.
+3. Treat an old epoch, old lease UUID, expired lease, or released lease as non-authoritative. Do not retry it as the old holder.
+4. Recovery uses the authorized takeover path with the observed expected epoch. Ordinary acquire is intentionally rejected for expired/released rows.
+5. If an external effect may already have happened, preserve evidence and do not assume lease fencing provides exactly-once replay safety.
+
+## Migration and rollback safety
+
+Migration `0016_salty_morlocks.sql` is additive: it creates two new tables and indexes without modifying existing authorization/session tables. Before rollout, normal database backup and migration verification still apply. Rolling application code back leaves unused additive tables in place; dropping tables is not part of automated rollback because it would destroy lease/audit evidence.
+
+## Security constraints
+
+- Tenant comes from authenticated gateway context, never a connector request field.
+- Logical agent, binding, connector, and scope identifiers use normalized constrained forms.
+- Takeover requires explicit gateway policy authorization and an expected epoch.
+- Default defense-in-depth TTL caps are 5 minutes for leases and 30 seconds for grants; policy may enforce stricter limits.
+- Validation and rejection audit complete before adapter side effects.
+- Existing authz and exact-action approval controls remain additional required gates; a valid connector lease does not bypass them.

+# Issue #755 — Logical Mos identity and connector lease fencing
+
+- Task: `MOS-PORT-M1-001`
+- Branch: `feat/mos-logical-identity-fencing`
+- Base: `origin/main`
+- Started: 2026-07-14
+- Working budget: 38K tokens (task ledger estimate); one implementation lane, bounded to M1.
+
+## Objective
+
+Implement the first runtime-portability security boundary: normalized logical-agent identity plus a PostgreSQL-durable exclusive connector lease and server-validated fencing grants.
+
+## Scope
+
+- Normalized identity contract independent of harness/provider-native session IDs.
+- DB migration/schema/repository for one lease per tenant/logical-agent/binding.
+- CAS acquire/takeover, monotonic epoch, TTL, heartbeat, release, expiry handling.
+- Server-derived grants bound to tenant, logical agent, binding, connector, scopes, expiry, and lease epoch.
+- Reject and credential-safely audit stale, expired, forged, unauthorized, cross-tenant, and cross-binding grants before adapter side effects.
+- Runtime adapter boundary consumes normalized lease context.
+- Unit, migration, close/reopen, concurrency, abuse, and gateway integration tests.
+- Required developer/operations documentation for schema and security behavior.
+
+## Explicit exclusions
+
+No checkpoint/handoff payloads, exactly-once journal/receipts, concrete Claude/Pi/Codex harness adapter, channel cutover, or full cross-harness failover E2E.
+
+## Reconciliation baseline
+
+- Prospective remediation handoff: `web1:coder1`; PR [#757](https://git.mosaicstack.dev/mosaicstack/stack/pulls/757), issue [#755](https://git.mosaicstack.dev/mosaicstack/stack/issues/755).
+- Before rebase: `dff8ce4f79ef90370c29d925002118a708010091`; required base: `origin/main` at `2e2280070ae67288be45f41743cf67052a8ca5a6`; original branch base: `d0771835542deab048ad8e79f271e3abdb6151f7`.
+- Provider metadata: #757 is open, targets `main`, head is `feat/mos-logical-identity-fencing`, prior CI is green, and the provider reports it is not mergeable because of conflicts.
+- Affected delivery paths: `apps/gateway/src/agent/agent.module.ts`; connector-lease gateway repository/service and three focused tests; `packages/agent/src/connector-lease.ts` plus test/export; `packages/types/src/agent/connector-lease.dto.ts` plus test/export; `packages/db/src/schema.ts`, migration `0016_salty_morlocks.sql`, Drizzle snapshot/journal; `docs/PRD.md`, `docs/SITEMAP.md`, MOS architecture/operations pages, this scratchpad, and `docs/tess/TASKS.md`.
+- Read-only merge-tree inspection found only `docs/PRD.md` and `docs/SITEMAP.md` conflicts. Current-main #756 channel contracts, #758 roster-v2 structural compiler, and Native Kanban SOT use distinct contract domains; no substantive architecture collision was identified before mechanical reconciliation.
+- Reconciliation constraints: retain all current-main #752/#756/#758/KBN content; add only nonduplicative #755 references; do not alter semantics or conflate connector leases/grants with Kanban task leases/fences, local Fleet leases, auth sessions, ResetSession generations, or federation grants.
+
+## Plan (TDD RED → GREEN → REFACTOR)
+
+1. Map existing contracts, DB/migration conventions, gateway authorization/audit boundaries, and test infrastructure.
+2. Add failing contract/repository/concurrency/restart/abuse/gateway tests and capture RED evidence.
+3. Implement the smallest normalized contracts, schema/migration/repository, grant validator, audit sink, and gateway service/adapter boundary needed to pass.
+4. Refactor for clear invariants and credential-safe observability; rerun focused suites.
+5. Run package/repo typecheck, lint, format, and appropriate tests.
+6. Run independent code + security review, remediate, and re-review.
+7. Inspect the final diff for security/scope drift; commit; queue guard; push; open PR with `Refs #755` and exact verification; stop without merge/issue closure.
+
+## Constraints and safety notes
+
+- `docs/tess/TASKS.md` is orchestrator-only and will not be edited.
+- Existing dirty `.mosaic/orchestrator/mission.json` and `.mosaic/orchestrator/session.lock` are launcher/orchestrator state and will not be staged or altered intentionally.
+- No client-supplied identity may confer authority.
+- No credential, token, or raw grant material may be persisted to audit/log output.
+- Existing authorization checks remain intact; fencing is an additional fail-closed layer.
+
+## Assumptions resolved from existing architecture
+
+- `ASSUMPTION:` M1 exposes no public lease endpoint. The gateway service is an internal policy surface with deny-all default policy because concrete connector activation/cutover is explicitly deferred.
+- `ASSUMPTION:` Fencing epochs use PostgreSQL `bigint` and cross-module decimal strings, preserving JSON portability without JavaScript number precision loss.
+- `ASSUMPTION:` Process-local grant provenance intentionally fails closed across restart; durable lease/epoch state survives and fresh grants require current policy + lease validation.
+
+## TDD evidence
+
+RED observed before implementation:
+
+- `corepack pnpm --filter @mosaicstack/types exec vitest run src/agent/connector-lease.dto.spec.ts` → failed to load missing `connector-lease.dto.js`.
+- `corepack pnpm --filter @mosaicstack/agent exec vitest run src/connector-lease.test.ts` → failed to load missing `connector-lease.js`.
+- Gateway focused tests failed before implementation because the new repository/service boundaries did not exist (workspace dependencies were then built before behavioral GREEN runs).
+
+GREEN to date:
+
+- Types contract: 6/6 passed.
+- Agent grant/fencing unit suite: 5/5 passed.
+- Gateway PGlite repository + policy/side-effect integration: 7/7 passed; 1 real-PostgreSQL test skipped when `DATABASE_URL` absent.
+- Real PostgreSQL focused run with configured `DATABASE_URL`: 1/1 passed (credential value not emitted in reports).
+
+## Documentation checklist
+
+- [x] `docs/PRD.md` contains current MOS-PORT M1 scope and acceptance criteria.
+- [x] Developer architecture: `docs/architecture/mos-runtime-portability-m1.md`.
+- [x] Admin/operations guidance: `docs/guides/mos-connector-lease-operations.md`.
+- [x] `docs/SITEMAP.md` links both pages.
+- [x] No user-guide change: M1 exposes no user-facing flow or channel cutover.
+- [x] No OpenAPI/endpoint-index change: M1 adds no HTTP endpoint.
+- [x] Migration/restart/rollback safety and credential-safe audit constraints documented.
+- [x] Canonical source remains in-repo; no external publishing action is in scope.
+- [x] Independent review confirms documentation matches implementation; implementation-specific findings were remediated.
+
+## Independent review and remediation
+
+Codex code/security review ran in multiple rounds. Findings and root-cause remediations:
+
+1. Policy could not inspect requested scope/TTL → policy subject now receives normalized requested scopes and explicit requested TTL.
+2. Unbounded authority lifetime → hard defaults cap leases at 5 minutes and grants at 30 seconds; overrides may only tighten; over-limit tests added.
+3. Cross-tenant denial could audit under submitted tenant → mismatch audit uses authenticated tenant plus sanitized `untrusted` target metadata; integration assertion added.
+4. Malformed forged grant could break the denial/audit path → runtime-safe shape validation with sanitized fallback audit; malformed-input test added.
+5. Gateway integration test depended on prior test state → denial test now seeds a unique binding itself; isolated `-t` run passed.
+6. Reviewer repeatedly identified launcher-generated `.mosaic/orchestrator/*` state; those files remain unstaged and excluded from the implementation commit.
+
+Latest independent security review: no critical/high/medium/low findings. Final commit-level code review remains to run after the intended diff is committed without launcher state.
+
+## Verification evidence
+
+- Focused contracts/fencing: types 6/6; agent 9/9.
+- Gateway focused PGlite repository/policy integration: 7/7; isolated denial test 1/1.
+- Real PostgreSQL close/reopen/CAS test: 1/1 with configured `DATABASE_URL`.
+- Root `corepack pnpm typecheck`: 42/42 Turbo tasks passed.
+- Root `corepack pnpm lint`: 23/23 Turbo tasks passed.
+- Root `corepack pnpm format:check`: all matched files passed.
+- Root `corepack pnpm test`: 42/42 Turbo tasks passed; gateway 616 passed / 12 environment-gated skipped; DB 19 passed / 7 environment-gated skipped; Mosaic 650 passed.
+
+## Known residual risks
+
+- Concrete connector policies and Claude/Pi/Codex adapters are intentionally deferred; production policy defaults deny-all.
+- Gateway pre-side-effect validation cannot make an external system exactly-once. Adapters must propagate/enforce the epoch at downstream effect boundaries; receipts/journaling are later #754 scope.
+- Migration rollback is additive-only; dropping lease/audit tables is intentionally manual to avoid destroying authority/audit evidence.
+
+## Commit-level review remediation
+
+- Commit-level Codex code review found one `should-fix`: heartbeat, release, and grant issuance authorized caller-supplied lease fields before canonical normalization.
+- TDD RED: the isolated gateway policy-boundary test showed mixed-case/padded logical agent, binding, connector, scope, and epoch values reaching policy unchanged.
+- Remediation: exported the coordinator's canonical lease normalizer and applied it at the gateway boundary before tenant/policy checks and coordinator dispatch for heartbeat, release, and grant issuance.
+- GREEN: isolated policy test 1/1; focused types 6/6, agent 9/9, gateway 8/8; root typecheck 42/42, lint 23/23, format check passed, and root tests 42/42 (gateway 617 passed / 12 environment-gated skipped).
+- Commit-level security review remained clean: no critical/high/medium/low findings.
+
+## Durable grant-expiry review remediation
+
+- Final commit review found a second `should-fix`: grant expiry was capped against submitted lease metadata after current-authority validation, rather than the durable lease row.
+- TDD RED: a crafted same-authority lease with a later submitted expiry produced a grant expiring after the durable row.
+- Remediation: grant authority fields and expiry now derive from the durable current lease; submitted scopes remain an additional narrowing constraint.
+- GREEN: focused agent fencing suite 10/10.
+
+## Current-main reconciliation (2026-07-14)
+
+- Rebased the existing PR branch from `dff8ce4f79ef90370c29d925002118a708010091` (old base `d0771835542deab048ad8e79f271e3abdb6151f7`) onto `origin/main` `2e2280070ae67288be45f41743cf67052a8ca5a6`; current uncommitted reconciliation head is `d190732a550918161b91d3eb54640f4ea0e2e499`.
+- Resolved only `docs/PRD.md` and `docs/SITEMAP.md`: preserved current-main #752 Native Kanban, #756 official-channel, and #758 FCM material; retained the nonduplicative #755 M1 workstream and placed its two documentation links in the existing Runtime-neutral Mos section. No #755 source semantics changed.
+- Compatibility review confirmed separate authority domains: connector lease/epoch/grant remains distinct from KBN task leases/fences, local Fleet roster lifecycle, auth sessions, ResetSession context, and federation grants. No channel cutover, adapter activation, checkpoint/exactly-once behavior, UI convergence, or #754 expansion was added.
+- Focused verification after building the required workspace dependencies: types contract 6/6; agent fencing/grant 10/10; gateway repository/PGlite and policy integration 8/8. The focused real-PostgreSQL test was skipped because `DATABASE_URL` was not configured; no credentials were inspected or emitted.
+- Generated schema check: `pnpm --filter @mosaicstack/db db:generate` reported no schema changes; migration `0016_salty_morlocks`, snapshot, and journal were unchanged by generation.
+- Full verification: `pnpm typecheck` 42/42; `pnpm lint` 23/23; `pnpm format:check` passed; `pnpm test` 42/42 (gateway 627 passed / 12 environment-gated skipped). Scoped diff check and local documentation-link scan passed.
+- Pending only: commit this reconciliation record, queue guard, force-with-lease push of the rebased existing branch, then fresh independent DB/code/security review and Ultron. Do not claim merge or issue closure.
+
+## Durable lifecycle-authority remediation (2026-07-14)
+
+- Independent review found that heartbeat and release authorized the submitted lease, allowing forged lifecycle scope data to influence policy before the durable row was consulted.
+- Remediation: lifecycle operations tenant-check the submitted lease, load the durable current lease, compare tenant, logical agent, binding, lease UUID, connector, epoch, and canonical ordered scopes, audit and deny any absent/mismatched authority, then run policy and coordinator lifecycle calls with the durable lease. Coordinator CAS/fencing checks remain unchanged.
+- Adversarial gateway integration coverage proves forged `tool.execute` scopes on a durable `runtime.send` lease deny before policy or mutation, preserve heartbeat/release state, and write a denial audit for both lifecycle actions; canonical heartbeat and release remain accepted.
+- Verification: focused types 6/6; agent 10/10; gateway PGlite integration/repository 9/9 with one `DATABASE_URL`-gated PostgreSQL test skipped; Drizzle check passed; root typecheck 42/42; lint 23/23; format check passed; root test 42/42 (gateway 628 passed / 12 environment-gated skipped).
+- Pending: commit, queue-guard, force-with-lease push, then independent DB/code/security rereview and CI. Do not merge or close #755.
