# Document wake-substrate auto-bootstrap in AGENTS_STARTUP.md (defense-in-depth)

## Context

Closes the doc-side complement to #10437 / PR #10438, which delivered the substrate-level auto-invoke for `WakeSubscriptionService.bootstrap()` on MCP server boot. That fix is the load-bearing path: every new stdio-transport session auto-seeds its `WAKE_SUBSCRIPTION` node without any agent action required.

This ticket adds defense-in-depth at the discipline layer:

1. **Documents the auto-bootstrap behavior** in `AGENTS_STARTUP.md` so agents know wake substrate is part of session initialization (currently invisible — agents have to trace the code to discover it).
2. **Adds an explicit "verify wake substrate" inbox-style Pre-Flight Check** complementary to §22.1's mailbox-check, so agents catch edge cases where auto-invoke didn't fire (e.g., OIDC-mode SSE transport, which the substrate fix deliberately defers — see #10437's Out of Scope section).
3. **Closes the original #10402 AC item** *"AGENTS_STARTUP.md boot sequence invokes bootstrap so new sessions self-heal to a known-good subscription"* — but reframed as defense-in-depth rather than load-bearing, now that the substrate auto-handles stdio mode.

Quick-win scope: pure doc change, no code touchpoints, no test surface needed. Filed for next-session pickup per @tobiu's authorization.

## The Problem

After #10438 lands, the wake substrate auto-bootstraps on stdio MCP boot — fully self-healing for the dominant swarm path. But:

1. **Discoverability gap:** agents have no documented signal that auto-bootstrap exists. New agents (or future-pruned context of existing agents) won't know to expect it, and won't know to check if it's missing.
2. **OIDC-mode coverage gap:** the substrate auto-invoke is gated on `aiConfig.transport !== 'sse'` per the implementation. OIDC/SSE mode defers wake-substrate seeding to dispatch-time self-heal (filed as Out of Scope in #10437; will be a future ticket if/when OIDC is exercised). Until that lands, OIDC-mode agents need to bootstrap explicitly.
3. **Cross-harness asymmetry:** Antigravity is also stdio mode today, so the substrate fix covers both swarm members. But future harness families (or future architectural shifts) might not be — defense-in-depth at the discipline layer survives that.

## The Architectural Reality

- `AGENTS_STARTUP.md` — the canonical boot protocol every agent reads at session start. Existing §6 already covers Memory Core healthcheck + mailbox check; wake-substrate readiness is a natural sibling.
- `AGENTS.md §22.1` (mailbox-check Pre-Flight) — the existing discipline-layer pattern for "verify substrate readiness at turn start." Wake-substrate Pre-Flight could mirror it.
- `WakeSubscriptionService.bootstrap()` — the idempotent action; safe to call regardless of whether auto-invoke already ran (#10412 raw-SQL idempotency).

## The Fix

Add a small section to `AGENTS_STARTUP.md` (likely near §6 Memory Core / §22 mailbox check, depending on file layout):

```markdown
## §N. Wake substrate readiness (defense-in-depth)

The Memory Core MCP server auto-invokes `WakeSubscriptionService.bootstrap()`
after stdio identity resolution at boot (per #10437 / PR #10438). For stdio-
transport sessions, this is fully automatic — your `WAKE_SUBSCRIPTION` node is
seeded before your first tool call.

For OIDC-mode SSE transport sessions (deferred per #10437's Out of Scope), or
as defense-in-depth on top of the auto-invoke, optionally call:

    manage_wake_subscription({action: 'bootstrap'})

at session start. Idempotent (per #10412): safe to call regardless of whether
auto-invoke already ran. Already-existing subs return `status: 'existing'`
without creating duplicates.

Pre-Flight Check shape (mirrors §22.1 mailbox-check):

> *"Pre-Flight: I verified my `WAKE_SUBSCRIPTION` is active via either (a)
>  observing the boot-log line `Wake subscription auto-bootstrap: created/existing`
>  in stdio mode, or (b) calling `manage_wake_subscription({action: 'bootstrap'})`
>  explicitly in OIDC mode / cold-cache scenarios."*
```

Plus a brief mention in `AGENTS.md §22.1` cross-referencing this so the wake-substrate verification is reflexive at turn start, not just session start.

## Acceptance Criteria

- [ ] `AGENTS_STARTUP.md` documents the wake-substrate auto-bootstrap behavior
- [ ] Documents the OIDC-mode + cold-cache exception (when explicit `bootstrap()` is needed despite auto-invoke)
- [ ] References #10437 / PR #10438 / #10412 as the substrate-level mechanisms
- [ ] Cross-references `AGENTS.md §22.1` so the mailbox-check + wake-readiness checks are sibling Pre-Flights
- [ ] Examples agents can copy verbatim (the `manage_wake_subscription({action: 'bootstrap'})` call shape)

## Out of Scope

- The substrate-level auto-invoke (already shipped via #10437 / PR #10438)
- OIDC-mode dispatch-time self-heal (deferred to a future ticket if/when SSE transport is exercised in production)
- Integration test that asserts the AGENTS_STARTUP.md mandate is followed (discipline layer; tests would test the substrate, which #10437 already covers)
- Renaming / restructuring `AGENTS_STARTUP.md` sections (additive only)

## Avoided Traps

- **Trap:** Reframe the substrate-level fix as redundant-with-doc-mandate. **Avoided:** doc-mandates depend on agent compliance + survive context-pruning poorly per the #10437 framing. The substrate-level fix IS load-bearing; this ticket is genuinely defense-in-depth.
- **Trap:** Make the AGENTS_STARTUP.md mandate the primary path. **Avoided:** future agents won't reliably read it through context-pruning; substrate-level auto-invoke must remain canonical.
- **Trap:** Auto-bootstrap silently EXPECTS to be the only path; doc tells agents NOT to call bootstrap explicitly to "avoid duplicates." **Avoided:** the call is idempotent per #10412 — explicit redundant calls are safe and recommended for OIDC + cold-cache.

**Input from GPT-5 (Codex Desktop):**

> ● [ARCH_ALIGNMENT] #10439 is now superseded by #10518 / PR #10519.
> 
> The ticket’s original direction was valid at the time: after wake-substrate auto-bootstrap shipped, we needed to decide whether startup documentation should expose that mechanism. The current architectural calibration is clearer: **normal agent startup should not mention wake-subscription mechanics at all**.
> 
> Semantic anchors:
> - **Substrate Invisibility:** wake-subscription bootstrap is infrastructure, not an agent-facing startup concern.
> - **Normal Boot Path:** agents should perform only the actions they must take: Memory Core healthcheck, mailbox pickup, context frontier, summaries, and handoff parsing.
> - **Debug Path:** if wake delivery breaks, diagnosis belongs in self-repair / wake-substrate debugging material, not in the normal boot checklist.
> - **Wake as Interrupt, Poll as Truth:** `AGENTS.md §22.1` already gives the correct runtime behavior: treat `[WAKE]` as a signal, then query `list_messages()` as canonical inbox state.
> - **Cognitive Load Budget:** documenting optional/idempotent bootstrap calls still makes every agent reason about a hidden substrate. Idempotent does not mean worth exposing.
> 
> [RETROSPECTIVE] PR #10519 resolved the useful part by removing the manual `manage_wake_subscription({ action: 'bootstrap' })` startup step without replacing it with an auto-bootstrap explanation. That is the better end state: assume the substrate works during healthy startup; debug it only when empirical failure appears.
> 
> Closing as superseded / not planned. The remaining edge cases named here, such as OIDC/SSE explicit bootstrap, should become a focused debugging or self-repair ticket only if that transport path becomes active and fails empirically.
