Adds a cross-reference so any agent (not just Claude) knows to look at
CLAUDE.md when it exists for review or deep-dive background.

Every commit MUST be signed off (git commit -s). Preserves the
copyright-holder's option to dual-license later — without a DCO/CLA
instrument, every external contribution erodes that option (ADR-0004).
Particularly load-bearing under multi-agent parallel authorship, where
multiple sessions commit in parallel and the DCO is the only per-commit
aggregation instrument.
Adds DCO.md with the full Linux-Foundation DCO text + the agents-sign-off-
with-the-human's-identity rule. AGENTS.md Git workflow gains the DCO bullet.
AGENTS.md +292 lines: the relay (model-agnostic MCP message-bus at
localhost:7110), PM session launch checklist (poller, watch.sh, kitty/tmux
spawner), session handoff (inbox.log / poller.log / relay-log.jsonl), PM
turn-start discipline (drain inbox, list_pending, git log, surface
proactively), multi-dev parallelism (5-rule checklist with the slice-3
anti-pattern), when-the-PM-is-blocked protocol. Plus the slice-4 PM
kickoff prompt under docs/superpowers/kickoffs/.
Load-bearing for the multi-agent workflow executing slice-4 (and beyond):
session discipline (turn-start polling, no standby mode, proactive
surfacing) was the prior failure mode; the prompt + these sections bake
the correction into AGENTS.md so a fresh PM agent session inherits it.
ADR-0007 (rent the trunk) + ADR-0008 (FOB/green-zone doctrine) propagation
into the narrative docs that orient contributors + readers. No code changes.
README:
- Wedge bullet 2: 'one secure auditable boundary' now lists media + local
reflexes + spend + tap + audit (was: trunk termination + media + spend).
Adds the honest caveat that PSTN media inside the boundary is the on-prem
*graduation* (ADR-0007), not a day-one claim.
- 'Is / isn't': 'isn't a TDM/PSTN-hardware PBX — *and not a SIP stack.*'
No first-party SIP (ADR-0007). PSTN reach is rented transport.
- Memory-safety pillar: 'rutster parses no SIP at all' — entire first-party
wire surface is WebRTC/RTP/SRTP + WebSocket tap/ingress, all memory-safe
Rust. The carrier-SIP interop tail lives outside the trust boundary.
- Spearhead step 5: 'Add a real phone number via rented transport' (was:
'Replace WebRTC ingress with a real PSTN trunk call'). Re-aims at the
AI-telephony frontier; no first-party SIP stack.
- References: 0007 supersedes 0003 in the highlighted ADR list.
ARCHITECTURE:
- New 'FOB and the green zone' section after the fused-vertical framing —
names the build-vs-reuse doctrine with the FOB member list + green-zone
member list, and restates memory-safety precisely ('FOB is 100%
memory-safe Rust; the green zone is trusted OSS kept outside the
boundary — not an over-claim that every byte is Rust').
- 'Inside the boundary': 'Carrier trunk — rented transport, not first-party'
replaces 'Trunk SIP termination — Rust-native.' PSTN audio arrives as
a media-leg ingress from a rented CPaaS raw-media fork or an out-of-tree
SBC for on-prem sovereignty.
- Biggest technical risk: 'No longer the SIP stack — because rutster no
longer builds one.' Retires ADR-0003's named schedule risk; redirects
to 'the reflex loop itself' (turn-taking, VAD-driven barge-in, jitter,
pacing) — which is also the differentiator.
PORT_PLAN:
- Design rule 4: 'rent it, don't own it' replaces ADR-0003's 'Rust-native
trunk SIP, no SBC shield.' ADR-0007 restores the rule's original instinct.
- SIP signaling (trunk) row: disposition flipped to 🔌 Rented / out-of-tree.
- Outbound registration row: disposition flipped to 🔌 Rented / out-of-tree
(handled by the rented transport or out-of-tree SBC; rutster parses no SIP).
- Spend/abuse engine row: 'co-located with call origination + the tap inside
the boundary' (was: 'co-located with trunk termination'). rutster mediates
both the provider call-control API and the brain tap — the brain never
holds the wire.
- Spearhead step 5: 'Add a real phone number via rented transport.'
- Open decisions: SIP line updated to 'Re-decided — ADR-0007.'
AGENTS.md:
- ADR list: adds 0007 and 0008 with annotations; marks 0003 as superseded
by 0007.
- Key decisions to respect: prepends the FOB/green-zone doctrine as the
*the* build-vs-reuse rule. 'When in doubt, default to green zone — the
FOB earns its members, it doesn't collect them. This is why the trunk is
rented (ADR-0007) and Valkey reused (ADR-0005), not rebuilt. Don't pull
green-zone plumbing into the core.'
Project orientation for any agent (human/AI/hybrid) working in the repo.
Covers: project structure (current + planned), build/lint/test commands,
Rust code style (formatting, naming, error handling, async/concurrency,
learner-facing documentation comments), terminology policy (inclusive
language + ICE-as-protocol-convention exception), architecture
pre-reading order, key decisions to respect, git workflow, and the
slice-1 boundaries (what NOT to add yet).
