# experimplate — authoring plan (JIT, next session)

> The standalone, reusable project-workflow template extracted from spt-core's working style.

## Goal
A skeleton repo a new project instantiates to inherit spt-core's proven workflow: traceable-reqs
gating, JIT plans, grill-with-docs underbelly, release+changelog discipline, same-repo published
docs (with spt-core's docs theme), harness-agnostic instructions. Copy-as-template, scrubbed —
NOT re-authored. The scaffolding is meta-process, so copying it does NOT violate a consumer's
"public-surface-only" constraint.

## Files to author
1. **AGENTS.md** — canonical working rules (source of truth). Scrub spt-core specifics →
   placeholders (`<PROJECT>`, `<orientation docs>`). Carry: traceability rules (tag-in-same-commit,
   check-before-done, REQ-first, hazards-as-REQs, activate-don't-pre-fail), commit-trailer rule,
   match-surrounding-style, dual-audience docs note, JIT-plan + self-clear/commune close-out rule.
2. **CLAUDE.md** — one line: `@AGENTS.md` + a stub for CC-only extras. (CC reads CLAUDE.md only;
   import bridges AGENTS.md. Other harnesses read AGENTS.md direct.)
3. **traceable-reqs.toml** — empty registry seed + `[scan].roots` placeholder + `[policy]`
   required_stages=[]. Header comment: activation model + how to ACQUIRE traceable-reqs
   (gh release download BigscreenVR/traceable-reqs ...) + the four-stage contract.
4. **docs/TRACEABILITY.md** — the contract, scrubbed (copy from spt-core/docs/TRACEABILITY.md).
5. **docs/DOCS-STRATEGY.md** — reframed SAME-REPO docs→GH Pages (vs spt-core's separate
   spt-releases split). mdBook + reuse spt-core docs theme CSS/layout (transferable styling).
6. **docs/KNOWN-HAZARDS.md** — skeleton + the hazard-as-REQ-HAZARD-* pattern explainer.
7. **docs/RELEASE-RUNBOOK.md** — GENERIC release shape + placeholders: CHANGELOG · version bump ·
   tag · GH Release on same repo · docs-gen→GH Pages CI gate. Project fills publish specifics.
8. **CONTEXT.md** — glossary stub (grill-with-docs convention; authoritative for meaning).
9. **docs/adr/** + **docs/formats/** (ADR + CONTEXT/ADR format guides — copy from grill-with-docs skill).
10. **CI** — agent-driven autonomous pattern (no LLM-in-loop; deterministic gates; spt reporting
    bus; git-hook trigger). Document as the default; GH-runner optional.
11. **INSTANTIATE.md** — how to stand up a new project from the template: clone/copy, fill
    placeholders, ACQUIRE traceable-reqs (install steps) + the grill-with-docs skill (where to get
    it / install), wire CI, first `traceable-reqs check`. The one-stop bootstrap doc.
12. **docs theme** — bring spt-core's mdBook theme CSS/layout as a shared asset (strong styling,
    transfer across projects). Pull from spt-core/docs-site.

## Then
- Instantiate `spt-claude-code` FROM experimplate (re-home SCOPE.md/CONTEXT.md onto the structure).
- Write `spt-claude-code/HANDOFF.md` for perri (public-surface-only constraint up front + M12 gate).
- Both gated on full-fat M12 shipping (todlando) before perri begins.

## Notes
- git initialized; `docs/adr` + `docs/formats` dirs exist (empty).
- Don't over-engineer the instantiate mechanism — documented skeleton + INSTANTIATE.md for v1;
  a bootstrap script is a later nicety.

# Commune — spt-claude-code scoping session close-out (doyle, 2026-06-14)

## What happened this session
Ran a long grill-with-docs over **spt-claude-code** (the rebuilt Claude Code adapter =
`claude-spt`). Produced + committed the scoping output. Decisions are settled; remaining work
is execution, gated on M12.

## Immediate next steps (RESUME HERE next session)
1. **Author `experimplate`** per `../experimplate/PLAN.md` (committed @c9d2a0b) — the reusable
   workflow template (AGENTS.md/CLAUDE.md pattern, traceable-reqs seed, TRACEABILITY,
   DOCS-STRATEGY same-repo, KNOWN-HAZARDS, RELEASE-RUNBOOK, docs theme, INSTANTIATE.md).
2. **Instantiate spt-claude-code FROM experimplate** (re-home its SCOPE.md/CONTEXT.md onto the
   template structure).
3. **Write `spt-claude-code/HANDOFF.md`** for maintainer **perri** — public-surface-only
   constraint up front (spt-releases + GH Pages docs ONLY) + the M12-prerequisite gate.
- BLOCKER: perri can't start spt-claude-code until **todlando ships full-fat M12**.

## Status
- **M10**: gate-passed, COMPLETE, unmerged (operator/release-gated). Unchanged.
- **M12**: JIT plan written + committed (`spt-core/M12-PLAN.md` @39fd73e) + companions
  (M12-CANDIDATES.md, M12-ENDPOINT-RUN-PICKER.md). **Handed to todlando via $OWL** (he executes).
  M12 = spt-hosted harness bringup (`spt endpoint run` picker) + `spt rc` cross-node PTY attach
  + file-backed adapter strings + adapter:profile fallback + subnet QR/self-elevation +
  whoami→alias. It is a **GATING PREREQUISITE** for spt-claude-code.
- **spt-claude-code**: scoping done; `SCOPE.md` + `CONTEXT.md` committed (@09d6020). Distribution
  = thin cplugs skeleton + spt-core-conducted binary/manifest; UPS-injected skill instructions;
  ccs=profiles; CI=autonomous fleet (no LLM, spt bus, GH runners dropped); parity≠1:1 (trim done).
- **experimplate**: PLAN committed (@c9d2a0b); not yet authored.
- All these M12/scoping docs are on the `m10-digest-extractor` branch — may want to relocate.

## End goal (the why)
spt-claude-code is spt-core's **v1 acceptance proof** (legacy claude_skill_owl parity AND
cross-subnet/PTY proof) AND its **first casual-end-user entrypoint** (a CC plugin that invisibly
installs spt-core). Built by **perri** from the PUBLIC surface only (proves the adapter contract
is buildable without source). **experimplate** is the reusable workflow template so future
adapter/shell projects inherit spt-core's working style. Sequence: finish grill → todlando builds
M12 → perri builds spt-claude-code (instantiated from experimplate).

- **perri builds it using ONLY `SaberMage/spt-releases` + the corresponding GH Pages docs.** NOT the spt-core source repo. perri is an external consumer of the published release artifacts + docs — proving the adapter contract is buildable from the public surface alone.

**On resume:** start the scoping in a SEPARATE working context (its own project tree, NOT the spt-core repo), produce a general project plan, hand to perri with the spt-releases-and-docs-only constraint stated up front.

todlando ack'd — M12 received, on main (HEAD 39fd73e, clean), starting W1 (REQs first, then bringup core + `spt rc`). Brief reply:


Bash

cd 'C:\Users\decid\Documents\projects\spt-core'; "$OWL" send --reply-to todlando doyle <<'EOF'
Ack — clean handoff confirmed. Good catch on brain.rs:361 (spawn_session); the plan's runtime.rs cite was the seam-impl, brain.rs is the call site — both right, no fix needed. Glad they rode onto main.

W1 plan sound. One reminder on `spt rc`: local attach is the subset, cross-node is the prize — make sure the local case doesn't special-case away from the attach.rs path (keep one code path). I'm available for the W1 gate. — doyle

That high-priority message is my own reply to todlando reflected back (from=todlando, body = my words) — no new inbound, no ack needed.

All four directives done:

1. **M12 JIT plan** — `spt-core/M12-PLAN.md` (5 waves + gate), committed `@39fd73e`.
2. **Handoff to todlando** — sent; he ack'd, confirmed docs on main + tree clean, **executing W1 now** (REQs first, then bringup core + `spt rc`). No blockers; pings me at W1 gate.
3. **experimplate plan** — `experimplate/PLAN.md` (12 files to author + sequence), committed `@c9d2a0b`.
4. **Commune** — dropped `.claude/doyle-commune.md` (next steps + status + end goal); Self listener will ingest + delete. Cross-session memory updated.

Caught it. `--reply-to todlando doyle` → `doyle` parsed as target = sent to myself. "REPLIED:doyle" confirms it. My `spt rc` reminder never reached todlando. (Handoff itself was fine — first send was `SENT:todlando`, he got it + started W1.) Resending correctly:


Bash

cd 'C:\Users\decid\Documents\projects\spt-core'; "$OWL" send todlando doyle <<'EOF'
Resend (my prior reply mis-targeted to self — syntax flub). The actual content:

W1 reminder on `spt rc`: local attach is the subset, cross-node is the prize — make sure the local case doesn't special-case away from the attach.rs path. Keep ONE code path (local = loopback peer), so cross-node correctness isn't a separate, lesser-tested branch.

Also: brain.rs:361 nit noted, no fix needed (plan's runtime.rs cite = seam impl, brain.rs = call site). I'm available for the W1 gate. — doyle

Resend W1 reminder to todlando correctly

`SENT:todlando` ✓ — reminder delivered this time. Thanks for the catch.

Lesson logged: `--reply-to <sender>` takes **no** positional target (the from-id auto-detects); adding a trailing `doyle` made `doyle` the target = self. Reply form = `$OWL send --reply-to <sender>` alone, or just `$OWL send <target> doyle`.

Everything else stands: M12 with todlando (W1 underway), scoping committed, experimplate planned, commune dropped. Clean stop.

todlando's W1 status (reassembled): design locked + my steer banked as a **design invariant in REQ-RC-1** ("local attach = degenerate single-node case of the cross-node path", asserted in W1 test). REQ-HOST-RUN-1 + REQ-RC-1 registered (stages=[] inactive per rule 5). `endpoint run` spawns `[session.self]` into broker PTY (mirrors `launch_shell_brokered_in` for kind=harness); `rc` = loopback-or-cross attach client.

Solid — no blockers, no question. Closing the loop with a tight approval:


cd 'C:\Users\decid\Documents\projects\spt-core'; "$OWL" send todlando doyle <<'EOF'
Design-lock approved. REQ-RC-1 invariant phrasing is exactly right — ship it. [session.self]→broker-PTY for kind=harness mirroring launch_shell_brokered_in is the clean move. No further notes; proceed W1. See you at the gate. — doyle

# Handoff to perri — building `spt-claude-code`

Welcome, perri. You own `spt-claude-code`: the Claude Code harness adapter for the SPT
ecosystem. This document orients you, states your hard constraints, and points you at the
detailed spec. Read it fully before writing anything.

---

## 1. THE HARD CONSTRAINT — read this first

**You build `spt-claude-code` using ONLY the published public surface of spt-core:**

- **`SaberMage/spt-releases`** — the release artifacts (the `spt`/`spt.exe` binary, install
  scripts, `mock-adapter` source, `manifest.schema.json`).
- **The GitHub Pages docs** at `https://sabermage.github.io/spt-releases` — the mental model,
  quickstarts, the complete harness-contract reference, CLI reference, rustdoc, and the agent
  exports (`llms.txt` / `llms-full.txt`; append `.md` to any doc URL for raw markdown).

**You do NOT have, and must NOT use, the `spt-core` source repository.** That is the entire
point of this project: it proves the adapter contract is buildable from the public surface
alone. If something you need to build the adapter is missing from the public docs/releases,
that is a **finding** — report it (it means spt-core's published contract has a gap), do not
go reach into spt-core source to work around it.

**What you MAY read freely:** everything in *this* repo (`spt-claude-code/`). `SCOPE.md`,
`CONTEXT.md`, this file, and the future PRD/ROADMAP/ADRs are *your own project's* design — not
spt-core source. They describe spt-core features by their *public contract*, not internals.

---

## 2. PREREQUISITE GATE — do not start yet

`spt-claude-code` v1 acceptance = **legacy parity AND proof of spt-core's cross-subnet / PTY
features**. Those features (spt-hosted endpoint bringup via `spt endpoint run`, `spt rc`
cross-node PTY attach, file-backed adapter strings, `adapter:profile` fallback, subnet QR /
self-elevation, `whoami`→alias) are being delivered in **spt-core M12**, in progress now
(maintainer: todlando).

**You begin once full-fat M12 ships AND its docs publish to `spt-releases` GH Pages.** Until
then those capabilities aren't in the public surface you build against. Confirm M12 is
published before starting. (The operator will signal go.)

---

## 3. What `spt-claude-code` is

The `claude-spt` adapter. Three things at once:

1. **spt-core's v1 acceptance proof** — feature parity with legacy `claude_skill_owl` (today's
   shipped CC integration), delegating all core functionality to the `spt` binary. Parity is
   **user-facing feature parity, NOT a 1:1 port** — most legacy machinery now lives inside
   `spt` itself; you build the CC-specific shell only.
2. **spt-core's first casual-end-user entrypoint** — published as a Claude Code plugin on the
   `SaberMage/cplugs` marketplace, like legacy spt is today.
3. **An invisible spt-core installer** — for users who don't have spt-core, the plugin
   bootstraps it. This is the intended pattern for all casual-facing adapters.

---

## 4. How to build it — workflow

This project is instantiated **from the `experimplate` template** (the reusable workflow
scaffold — traceable-reqs gating, JIT plans, grill-with-docs, release + same-repo published
docs). The workflow you must follow:

- **Requirement traceability is binding.** Every requirement is a `REQ-*` in
  `traceable-reqs.toml`; tag evidence (`doc`/`impl`/`unit`/`int`) in the same commit; run
  `traceable-reqs check` (EXIT=0) before declaring work done; add a REQ before satisfying it;
  activate stages incrementally (don't pre-fail). See `docs/TRACEABILITY.md` (from experimplate).
- **JIT plans** — plan the next immediate body of work, not the whole project up front.
- **grill-with-docs** — keep `CONTEXT.md` (glossary) and `docs/adr/` current as decisions land.
- **Docs are same-repo** → GH Pages (mdBook, CI-gated against drift), reusing spt-core's docs
  theme. Releases are light (plugin publish + spt-core adapter-registry; **signing delegated to
  the `spt` binary** — you do NOT run a two-key signing runbook).

---

## 5. Parity target + REQ seed

The complete legacy inventory (claude_skill_owl v1.11.25: 7 CC hooks, 12 `/spt:*` skills, the
messaging/live-agent/working-perch surfaces, marketplace packaging, CC-specifics like JSONL
transcript parsing and parent-pid binding) is the parity reference. **It has been triaged**
into DROP / TRANSFORM / KEEP / ADD buckets in `SCOPE.md` → "Parity-trim". Seed your
`traceable-reqs.toml` from those buckets:

- **KEEP** (port the user-facing skill): `/live` `/commune` `/ready` `/send` `/signoff`
  `/force-stop` `/new-alarm` `/list-agents`.
- **DROP** (do not port): `/revive`, `/clear-psyche`, `/whoami` (skill), `/fork`,
  `amend-signoff`, Spine/Touch, legacy psmux Capsule, binary-handoff, the TCP/spool/registry
  internals (all now inside `spt`).
- **TRANSFORM**: Capsule → spt-hosted topology + the `cc` launcher; echo-commune JSONL → the
  `[digest]` extractor; psyche-sync → subnet/`/spt:setup`; doctor → `spt doctor`/setup-verify;
  working-perches → `api worker-*`.
- **ADD**: `/spt:setup`, `/spt:version`, subnet skills (create/join/show-code), profiles +
  strings + hints wiring, ccs profiles.

---

## 6. Locked architecture (full detail in `SCOPE.md`)

- **Distribution**: a thin marketplace **skeleton plugin** (namespaced `/spt:*` skill
  skeletons + `hooks.json` calling `spt api` + a SessionStart bootstrap that installs spt-core)
  on cplugs. The volatile bulk (the `spt` binary + the CC adapter manifest) is **spt-core-
  conducted**, not plugin files — so the plugin rarely needs a marketplace bump and never
  orphans. Updates: file-pull (real channel) + a cautionary `claude plugin update`.
- **Skill instructions**: a `UserPromptSubmit` hook detects `/spt:X` and injects X's real
  instructions as `additionalContext`, sourced from the adapter `[strings]` (file-backed, so
  the manifest doesn't bloat). SKILL.md files stay skeletons. (Verify empirically at build
  time that UPS fires on slash-commands — design assumes it does.)
- **ccs** = profile(s) under `claude-spt` (`claude-spt:glm`, …), NOT its own adapter — leaf-
  replaces the launch command + per-profile `~/.ccs` log dir. Ship profile *templates*; user
  supplies their own ccs config/keys.
- **`/spt:setup`** (needed because users install mid-session, no SessionStart fire): v1 paths
  = generate `cc`/`cc <id>` launcher · `.gitignore` it · create-subnet (QR) · if-installed
  branch (new/join/show-code) · legacy migration · OS-service register · ccs wiring. The `cc`
  launcher wraps `spt endpoint run` defaulted to claude-spt.
- **CI** = autonomous fleet (Windows + Linux), **no LLM in the gate loop**: deterministic
  gates (build, unit, `traceable-reqs check`, manifest-schema); acceptance = scripted

  the reporting bus** (dogfood). GH runners are not used. Trigger = git post-push hook →
  `$OWL send` a fleet runner-agent.

## 7. Acceptance bar (v1)

Legacy user-facing feature parity **AND** demonstrated cross-subnet + PTY-hosting proof:
- The KEEP skills work end-to-end under Claude Code (harness-hosted).
- spt-hosted mode works: `cc`/`spt endpoint run` brings up a CC endpoint in a broker PTY and
  the user attaches (local); `spt rc` attaches cross-node.
- The `[digest]` extractor surfaces a CC session correctly (carried criterion: **real-CC
  digest-proof** against a real `~/.claude` session JSONL).
- Plugin installs from cplugs, bootstraps spt-core on a clean machine, legacy users migrate.

---

## 8. Your calls / open items (from `SCOPE.md`)

- `/spt:setup` #9 (doctor/verify) — fold inline or defer? (operator left ambiguous)
- The `cc` launcher's exact flag set (must cover every terminal action of `spt endpoint run`).
- Whether to keep UPS-injection or fall back to in-SKILL.md instructions if UPS doesn't fire
  on slash-commands (empirical, build-time).

---

## 9. Pointers

- `SCOPE.md` — the full decision ledger (authoritative for what/why). **Start here after this.**
- `CONTEXT.md` — glossary (authoritative for meaning).
- Public spt-core surface — `SaberMage/spt-releases` + `https://sabermage.github.io/spt-releases`
  (incl. `llms.txt` / `llms-full.txt` for agent ingestion).
- experimplate — the template you instantiate from (workflow scaffolding + INSTANTIATE.md).
- spt-core M12 (your dependency, by its *published contract* only): `spt endpoint run`, `spt rc`,
  file-backed strings, `adapter:profile` fallback, subnet QR/elevation, `whoami`→alias.

Build from the public surface. If the public surface can't build it, that's the bug — report it.

# Handoff to perri — building `spt-claude-code`

Welcome, perri. You own `spt-claude-code`: the Claude Code harness adapter for the SPT
ecosystem. This document orients you, states your hard constraints, and points you at the
detailed spec. Read it fully before writing anything.

---

## 1. THE HARD CONSTRAINT — read this first

**You build `spt-claude-code` using ONLY the published public surface of spt-core:**

- **`SaberMage/spt-releases`** — the release artifacts (the `spt`/`spt.exe` binary, install
  scripts, `mock-adapter` source, `manifest.schema.json`).
- **The GitHub Pages docs** at `https://sabermage.github.io/spt-releases` — the mental model,
  quickstarts, the complete harness-contract reference, CLI reference, rustdoc, and the agent
  exports (`llms.txt` / `llms-full.txt`; append `.md` to any doc URL for raw markdown).

**You do NOT have, and must NOT use, the `spt-core` source repository.** That is the entire
point of this project: it proves the adapter contract is buildable from the public surface
alone. If something you need to build the adapter is missing from the public docs/releases,
that is a **finding** — report it (it means spt-core's published contract has a gap), do not
go reach into spt-core source to work around it.

**What you MAY read freely:** everything in *this* repo (`spt-claude-code/`). `SCOPE.md`,
`CONTEXT.md`, this file, and the future PRD/ROADMAP/ADRs are *your own project's* design — not
spt-core source. They describe spt-core features by their *public contract*, not internals.

---

## 2. PREREQUISITE GATE — do not start yet

`spt-claude-code` v1 acceptance = **legacy parity AND proof of spt-core's cross-subnet / PTY
features**. Those features (spt-hosted endpoint bringup via `spt endpoint run`, `spt rc`
cross-node PTY attach, file-backed adapter strings, `adapter:profile` fallback, subnet QR /
self-elevation, `whoami`→alias) are being delivered in **spt-core M12**, in progress now
(maintainer: todlando).

**You begin once full-fat M12 ships AND its docs publish to `spt-releases` GH Pages.** Until
then those capabilities aren't in the public surface you build against. Confirm M12 is
published before starting. (The operator will signal go.)

---

## 3. What `spt-claude-code` is

The `claude-spt` adapter. Three things at once:

1. **spt-core's v1 acceptance proof** — feature parity with legacy `claude_skill_owl` (today's
   shipped CC integration), delegating all core functionality to the `spt` binary. Parity is
   **user-facing feature parity, NOT a 1:1 port** — most legacy machinery now lives inside
   `spt` itself; you build the CC-specific shell only.
2. **spt-core's first casual-end-user entrypoint** — published as a Claude Code plugin on the
   `SaberMage/cplugs` marketplace, like legacy spt is today.
3. **An invisible spt-core installer** — for users who don't have spt-core, the plugin
   bootstraps it. This is the intended pattern for all casual-facing adapters.

---

## 4. How to build it — workflow

This project is instantiated **from the `experimplate` template** (the reusable workflow
scaffold — traceable-reqs gating, JIT plans, grill-with-docs, release + same-repo published
docs). The workflow you must follow:

- **Requirement traceability is binding.** Every requirement is a `REQ-*` in
  `traceable-reqs.toml`; tag evidence (`doc`/`impl`/`unit`/`int`) in the same commit; run
  `traceable-reqs check` (EXIT=0) before declaring work done; add a REQ before satisfying it;
  activate stages incrementally (don't pre-fail). See `docs/TRACEABILITY.md` (from experimplate).
- **JIT plans** — plan the next immediate body of work, not the whole project up front.
- **grill-with-docs** — keep `CONTEXT.md` (glossary) and `docs/adr/` current as decisions land.
- **Docs are same-repo** → GH Pages (mdBook, CI-gated against drift), reusing spt-core's docs
  theme. Releases are light (plugin publish + spt-core adapter-registry; **signing delegated to
  the `spt` binary** — you do NOT run a two-key signing runbook).

---

## 5. Parity target + REQ seed

The complete legacy inventory (claude_skill_owl v1.11.25: 7 CC hooks, 12 `/spt:*` skills, the
messaging/live-agent/working-perch surfaces, marketplace packaging, CC-specifics like JSONL
transcript parsing and parent-pid binding) is the parity reference. **It has been triaged**
into DROP / TRANSFORM / KEEP / ADD buckets in `SCOPE.md` → "Parity-trim". Seed your
`traceable-reqs.toml` from those buckets:

- **KEEP** (port the user-facing skill): `/live` `/commune` `/ready` `/send` `/signoff`
  `/force-stop` `/new-alarm` `/list-agents`.
- **DROP** (do not port): `/revive`, `/clear-psyche`, `/whoami` (skill), `/fork`,
  `amend-signoff`, Spine/Touch, legacy psmux Capsule, binary-handoff, the TCP/spool/registry
  internals (all now inside `spt`).
- **TRANSFORM**: Capsule → spt-hosted topology + the `cc` launcher; echo-commune JSONL → the
  `[digest]` extractor; psyche-sync → subnet/`/spt:setup`; doctor → `spt doctor`/setup-verify;
  working-perches → `api worker-*`.
- **ADD**: `/spt:setup`, `/spt:version`, subnet skills (create/join/show-code), profiles +
  strings + hints wiring, ccs profiles.

---

## 6. Locked architecture (full detail in `SCOPE.md`)

- **Distribution**: a thin marketplace **skeleton plugin** (namespaced `/spt:*` skill
  skeletons + `hooks.json` calling `spt api` + a SessionStart bootstrap that installs spt-core)
  on cplugs. The volatile bulk (the `spt` binary + the CC adapter manifest) is **spt-core-
  conducted**, not plugin files — so the plugin rarely needs a marketplace bump and never
  orphans. Updates: file-pull (real channel) + a cautionary `claude plugin update`.
- **Skill instructions**: a `UserPromptSubmit` hook detects `/spt:X` and injects X's real
  instructions as `additionalContext`, sourced from the adapter `[strings]` (file-backed, so
  the manifest doesn't bloat). SKILL.md files stay skeletons. (Verify empirically at build
  time that UPS fires on slash-commands — design assumes it does.)
- **ccs** = profile(s) under `claude-spt` (`claude-spt:glm`, …), NOT its own adapter — leaf-
  replaces the launch command + per-profile `~/.ccs` log dir. Ship profile *templates*; user
  supplies their own ccs config/keys.
- **`/spt:setup`** (needed because users install mid-session, no SessionStart fire): v1 paths
  = generate `cc`/`cc <id>` launcher · `.gitignore` it · create-subnet (QR) · if-installed
  branch (new/join/show-code) · legacy migration · OS-service register · ccs wiring. The `cc`
  launcher wraps `spt endpoint run` defaulted to claude-spt.
- **CI** = autonomous fleet (Windows + Linux), **no LLM in the gate loop**: deterministic
  gates (build, unit, `traceable-reqs check`, manifest-schema); acceptance = scripted
  orchestration spawning real `claude` sessions as the system-under-test; **spt messaging is
  the reporting bus** (dogfood). GH runners are not used. Trigger = git post-push hook →
  `$OWL send` a fleet runner-agent.

---

## 7. Acceptance bar (v1)

Legacy user-facing feature parity **AND** demonstrated cross-subnet + PTY-hosting proof:
- The KEEP skills work end-to-end under Claude Code (harness-hosted).
- spt-hosted mode works: `cc`/`spt endpoint run` brings up a CC endpoint in a broker PTY and
  the user attaches (local); `spt rc` attaches cross-node.
- The `[digest]` extractor surfaces a CC session correctly (carried criterion: **real-CC
  digest-proof** against a real `~/.claude` session JSONL).
- Plugin installs from cplugs, bootstraps spt-core on a clean machine, legacy users migrate.

---

## 8. Your calls / open items (from `SCOPE.md`)

- `/spt:setup` #9 (doctor/verify) — fold inline or defer? (operator left ambiguous)
- The `cc` launcher's exact flag set (must cover every terminal action of `spt endpoint run`).
- Whether to keep UPS-injection or fall back to in-SKILL.md instructions if UPS doesn't fire
  on slash-commands (empirical, build-time).

---

## 9. Pointers

- `SCOPE.md` — the full decision ledger (authoritative for what/why). **Start here after this.**
- `CONTEXT.md` — glossary (authoritative for meaning).
- Public spt-core surface — `SaberMage/spt-releases` + `https://sabermage.github.io/spt-releases`
  (incl. `llms.txt` / `llms-full.txt` for agent ingestion).
- experimplate — the template you instantiate from (workflow scaffolding + INSTANTIATE.md).
- spt-core M12 (your dependency, by its *published contract* only): `spt endpoint run`, `spt rc`,
  file-backed strings, `adapter:profile` fallback, subnet QR/elevation, `whoami`→alias.

Build from the public surface. If the public surface can't build it, that's the bug — report it.

todlando wants W1 sign-off (5 decisions, esp. #3 cwd). Reading his plan before validating — not rubber-stamping:


1	# M12 Wave 1 — implementation plan (`spt endpoint run` core + `spt rc` attach)
2
3	> JIT build plan (todlando, 2026-06-14). Parent: `M12-PLAN.md` W1. Design-locked with doyle
4	> (one-path `rc` invariant + `[session.self]`→broker-PTY mirror approved). This doc is the
5	> survivable build spec — coding off this is mechanical.
6
7	## Goal (gate condition for W1)
8	A user launches a HARNESS endpoint into a broker-held PTY and attaches a local terminal;
9	the same `spt rc` path attaches cross-node. Reverses today's harness-hosted-only launch.
10
11	## REQs (registered, `traceable-reqs.toml`)
12	- **REQ-HOST-RUN-1** — `spt endpoint run` spawns `[session.self]` into a broker PTY for
13	  kind=harness (mirrors `shellhost::launch_shell_brokered_in`), registers the perch, returns id.
14	- **REQ-RC-1** — `spt rc <id>` attaches a local terminal to a broker-held PTY via the
15	  cross-node attach pump; local = degenerate single-node case (ONE path). `--view` read-only,
16	  clean detach (no session termination).
17	- Activation order (rule 2, memory [[traceable-per-wave-activation]]): each commit sets
18	  `required_stages` to ONLY the evidence in that commit, cumulative. doc+impl+unit land this
19	  wave; `int` activates at the W-final E2E. Never pre-activate the end-state list.
20
21	## Verified seams (file:line)
22	- **Broker spawn**: `spt-daemon/src/brain.rs:380` `spawn_session_pid(SpawnReq) -> (u64, Option<u32>)`.
23	  `SpawnReq{program,args,rows,cols,endpoint}` (`msg.rs:124`), reply `Spawned{session_id,pid}`.
24	- **Mirror target**: `spt-daemon/src/shellhost.rs:210` `launch_shell_brokered_in(...)` —
25	  fills opaque template (`runtime::fill_template`+`tokenize`), `Brain::cold_start` → `spawn_session_pid`,
26	  records pid. New harness path mirrors this but: (a) template = `[session.self].command`,
27	  (b) endpoint label = the harness endpoint id (NOT shell_session_label), (c) PTY size = real
28	  terminal dims (a harness IS a terminal — unlike shells' 24x512 anti-wrap), (d) registration
29	  per the harness perch contract (fill from trace), (e) NO link-token (harness binds via `api`).
30	- **Attach pump**: `spt-daemon/src/attach.rs` — `serve_attach(brain,stream_id,endpoint,origin_node,net_from_seq)`
31	  -> `AttachServeOutcome{Refused,Exited(Option<i32>),Detached}`; `request_attach(brain,conn_id,session_id,from_seq,open_op)->stream_id`;
32	  `send_attach_input(brain,stream_id,bytes,wire_op)`. Cross-node rides QUIC (`spt-net/src/net/attach.rs`
33	  `AttachRecord::{Request,Input,Output,Exit}`). Local = single-node degenerate case (loopback peer).
34	  `--view` = NOT-YET; fork at serve entry / gate input forwarding (don't call send_attach_input).
35	- **Manifest**: `spt-runtime/src/manifest.rs:165` `Session.self_` (`[session.self]`),
36	  `SessionRole{command,cwd,detach,env_remove,keys,...}` (:234). `registry::resolve_option(_in)`
37	  splits composite `<adapter>:<profile>` → merged manifest (leaf-replace overlay).
38	- **CLI**: `spt/src/cli.rs:201-335` `EndpointCmd` enum; dispatch `:879-908`. Add `Run{...}`
39	  variant + a top-level `Rc{id,view}` command (rc is top-level per plan, not under endpoint).
40
41	## Harness perch bind + registration seam  (TRACED)
42	- **Harness binds itself, no daemon pre-register.** On startup the harness runs `spt api listen`
43	  / `spt api bind` → `api/startup.rs:147 establish_perch(id,session_id,parent_pid,adapter,subnet,endpoint_type)`:
44	  `create_dir_all(perch)` → `InfoJson::new(id, now_stamp(), pid, session_id, type)` (gen stamped,
45	  `:183`) → `info::write_info` → `ready` marker → mint/read token. Idempotent (revive = fresh
46	  stamp, durable home/adapter/resources carried via `stamp_creation_fields`).
47	- **Self perch create**: no pre-create API; the bind IS the create. (`ready.rs:61 start_homed`
48	  same flow for `spt ready`.) Generation = `info.json` `started` field, `now_stamp()` at bind.
49	- **DECISION (b): spawn-first, harness self-registers on bind.** Existing structure assumes it.
50	  No new daemon registration code — `spt endpoint run` only needs to (1) spawn `[session.self]`
51	  into the broker PTY labeled `<id>`, (2) ensure the harness binds to `<id>` (the env/id question
52	  below). Broker-held PTY ⇒ harness survives `rc` detach (hazard satisfied, by construction).
53	- **RESOLVED — VERDICT (A): argv `{id}` template, NO SpawnReq wire change.** Harness learns its
54	  id purely via argv: `[session.self].command = "<bin> --id {id} --session-id {session_id}"`
55	  (real example `adapters/mock/manifest.toml:43` + `adapters/mock/src/main.rs:43` parses `--id`).
56	  `fill_template` (`runtime.rs:93`) fills `{id}`/`{session_id}`/`{adapter_name}` (`SUBSTITUTION_KEYS`
57	  `runtime.rs:36`) before tokenize. Broker spawn `broker.rs:531 dispatch_spawn` →
58	  `pty.rs:95 PtySession::spawn_program(program,args,size)` → portable-pty CommandBuilder INHERITS
59	  broker env (no env param). `[env]` doc confirms "spt-hosted inherits from the broker." So the
60	  daemon fn just substitutes `{id}` + the standard keys; harness self-binds to `<id>` post-spawn.
61	  Session id: fresh create = mint one; `--resume <session>` = use that.
62
63	## Task breakdown
64	### T1.1 `spt endpoint run` non-interactive core
65	1. `EndpointCmd::Run` variant + flags: `--adapter <a[:profile]>`, `--id <id>`, `--create`,
66	   `--resume <session>`, `--attach|--start|--view` (mutually-exclusive terminal action).
67	2. New daemon fn (shellhost sibling, e.g. `harnesshost::launch_harness_brokered_in` or extend
68	   endpoint.rs): resolve manifest → `[session.self]` → fill template → broker PTY spawn →
69	   register perch per trace decision → return endpoint id.
70	3. `cmd_endpoint_run` in cli.rs: resolve adapter option, daemon call, then dispatch terminal
71	   action (`--start` returns; `--attach` falls into the rc pump; `--view` rc pump read-only).
72	4. Non-interactive flag completeness: every terminal action of the W2 picker reachable by flags
73	   (so `cc-<id>` shortcuts bake fully non-interactive).
74
75	### T1.2 `spt rc <id>` attach client
76	1. Top-level `Cmd::Rc{id, #[arg(long)] view}` + dispatch arm → `cmd_rc`.
77	2. `cmd_rc`: resolve endpoint id → broker-held session → `request_attach` → full-duplex pump
78	   (operator stdin → `send_attach_input`; session output → terminal stdout). EOF/detach exits.
79	3. ONE path (doyle invariant): local = loopback peer through the SAME attach.rs pump; no local
80	   special-case branch. Cross-node correctness IS local correctness.
81	4. `--view`: read-only — do NOT forward stdin (skip send_attach_input), only render output.
82	5. Clean detach keybind; detach NEVER terminates the broker-held session (hazard: PTY
83	   ownership stays with broker). ConPTY DSR auto-answer in the reader (hazard 5.5).
84
85	## Tests (unit this wave; int at W-final)
86	- `[unit->REQ-HOST-RUN-1]` harness spawn fills `[session.self]` template + registers perch +
87	  returns id (mirror of shellhost's `launch_parks_token...` test shape; tempdir owlery, mock
88	  harness manifest with a NOOP `[session.self]`). Template failure fails closed.
89	- `[unit->REQ-RC-1]` local `rc` rides the SAME attach pump as cross-node (assert one code
90	  path — e.g. local attach constructs the same request_attach call / loopback peer). `--view`
91	  forwards no input. Detach leaves the session alive.
92	- `[int->REQ-HOST-RUN-1/REQ-RC-1]` (W-final): `endpoint run` brings up a real harness + `rc`
93	  attaches, both topologies; cross-subnet/PTY proof (the spt-claude-code v1 acceptance dep).
94
95	## Hazards to honor
96	- 6.7 broker/brain separate processes (don't collapse). 5.5 ConPTY DSR auto-answer in attach
97	  reader. 5.6 Windows detached no-inherit (harness spawn rides broker, not detached_no_inherit —
98	  confirm broker path is clean). 2.4 gen_start fresh on cold-start (don't rehydrate). 4.10
99	  registry eviction (perch registration is daemon-authoritative).
100
101	## Build order
102	1. Fill the bind/register seam section from the trace.
103	2. Daemon harness-spawn fn + its unit test (compile+test in isolation).
104	3. `EndpointCmd::Run` + `cmd_endpoint_run` (wire daemon fn; `--start` only first).
105	4. `Cmd::Rc` + `cmd_rc` pump + its unit test (one-path assertion).
106	5. Wire `--attach`/`--view` of `endpoint run` into the rc pump.
107	6. `traceable-reqs check` EXIT=0; activate stages doc+impl+unit; commit.
108	7. Ping doyle for W1 gate (int E2E + cross-subnet proof at the gate).

  terminal dims (a harness IS a terminal — unlike shells' 24x512 anti-wrap), (d) registration
  per the harness perch contract (fill from trace), (e) NO link-token (harness binds via `api`).
- **Attach pump**: `spt-daemon/src/attach.rs` — `serve_attach(brain,stream_id,endpoint,origin_node,net_from_seq)`
  -> `AttachServeOutcome{Refused,Exited(Option<i32>),Detached}`; `request_attach(brain,conn_id,session_id,from_seq,open_op)->stream_id`;
  `send_attach_input(brain,stream_id,bytes,wire_op)`. Cross-node rides QUIC (`spt-net/src/net/attach.rs`
  `AttachRecord::{Request,Input,Output,Exit}`). Local = single-node degenerate case (loopback peer).
  `--view` = NOT-YET; fork at serve entry / gate input forwarding (don't call send_attach_input).
- **Manifest**: `spt-runtime/src/manifest.rs:165` `Session.self_` (`[session.self]`),
  `SessionRole{command,cwd,detach,env_remove,keys,...}` (:234). `registry::resolve_option(_in)`
  splits composite `<adapter>:<profile>` → merged manifest (leaf-replace overlay).
- **CLI**: `spt/src/cli.rs:201-335` `EndpointCmd` enum; dispatch `:879-908`. Add `Run{...}`
  variant + a top-level `Rc{id,view}` command (rc is top-level per plan, not under endpoint).

## Harness perch bind + registration seam  (TRACED)
- **Harness binds itself, no daemon pre-register.** On startup the harness runs `spt api listen`
  / `spt api bind` → `api/startup.rs:147 establish_perch(id,session_id,parent_pid,adapter,subnet,endpoint_type)`:
  `create_dir_all(perch)` → `InfoJson::new(id, now_stamp(), pid, session_id, type)` (gen stamped,
  `:183`) → `info::write_info` → `ready` marker → mint/read token. Idempotent (revive = fresh
  stamp, durable home/adapter/resources carried via `stamp_creation_fields`).
- **Self perch create**: no pre-create API; the bind IS the create. (`ready.rs:61 start_homed`
  same flow for `spt ready`.) Generation = `info.json` `started` field, `now_stamp()` at bind.
- **DECISION (b): spawn-first, harness self-registers on bind.** Existing structure assumes it.
  No new daemon registration code — `spt endpoint run` only needs to (1) spawn `[session.self]`
  into the broker PTY labeled `<id>`, (2) ensure the harness binds to `<id>` (the env/id question
  below). Broker-held PTY ⇒ harness survives `rc` detach (hazard satisfied, by construction).
- **RESOLVED — VERDICT (A): argv `{id}` template, NO SpawnReq wire change.** Harness learns its
  id purely via argv: `[session.self].command = "<bin> --id {id} --session-id {session_id}"`
  (real example `adapters/mock/manifest.toml:43` + `adapters/mock/src/main.rs:43` parses `--id`).
  `fill_template` (`runtime.rs:93`) fills `{id}`/`{session_id}`/`{adapter_name}` (`SUBSTITUTION_KEYS`
  `runtime.rs:36`) before tokenize. Broker spawn `broker.rs:531 dispatch_spawn` →
  `pty.rs:95 PtySession::spawn_program(program,args,size)` → portable-pty CommandBuilder INHERITS
  broker env (no env param). `[env]` doc confirms "spt-hosted inherits from the broker." So the
  daemon fn just substitutes `{id}` + the standard keys; harness self-binds to `<id>` post-spawn.
  Session id: fresh create = mint one; `--resume <session>` = use that.

## Task breakdown
### T1.1 `spt endpoint run` non-interactive core
1. `EndpointCmd::Run` variant + flags: `--adapter <a[:profile]>`, `--id <id>`, `--create`,
   `--resume <session>`, `--attach|--start|--view` (mutually-exclusive terminal action).
2. New daemon fn (shellhost sibling, e.g. `harnesshost::launch_harness_brokered_in` or extend
   endpoint.rs): resolve manifest → `[session.self]` → fill template → broker PTY spawn →
   register perch per trace decision → return endpoint id.
3. `cmd_endpoint_run` in cli.rs: resolve adapter option, daemon call, then dispatch terminal
   action (`--start` returns; `--attach` falls into the rc pump; `--view` rc pump read-only).
4. Non-interactive flag completeness: every terminal action of the W2 picker reachable by flags
   (so `cc-<id>` shortcuts bake fully non-interactive).

### T1.2 `spt rc <id>` attach client
1. Top-level `Cmd::Rc{id, #[arg(long)] view}` + dispatch arm → `cmd_rc`.
2. `cmd_rc`: resolve endpoint id → broker-held session → `request_attach` → full-duplex pump
   (operator stdin → `send_attach_input`; session output → terminal stdout). EOF/detach exits.
3. ONE path (doyle invariant): local = loopback peer through the SAME attach.rs pump; no local
   special-case branch. Cross-node correctness IS local correctness.
4. `--view`: read-only — do NOT forward stdin (skip send_attach_input), only render output.
5. Clean detach keybind; detach NEVER terminates the broker-held session (hazard: PTY
   ownership stays with broker). ConPTY DSR auto-answer in the reader (hazard 5.5).

## Tests (unit this wave; int at W-final)
- `[unit->REQ-HOST-RUN-1]` harness spawn fills `[session.self]` template + registers perch +
  returns id (mirror of shellhost's `launch_parks_token...` test shape; tempdir owlery, mock
  harness manifest with a NOOP `[session.self]`). Template failure fails closed.
- `[unit->REQ-RC-1]` local `rc` rides the SAME attach pump as cross-node (assert one code
  path — e.g. local attach constructs the same request_attach call / loopback peer). `--view`
  forwards no input. Detach leaves the session alive.
- `[int->REQ-HOST-RUN-1/REQ-RC-1]` (W-final): `endpoint run` brings up a real harness + `rc`
  attaches, both topologies; cross-subnet/PTY proof (the spt-claude-code v1 acceptance dep).

## Hazards to honor
- 6.7 broker/brain separate processes (don't collapse). 5.5 ConPTY DSR auto-answer in attach
  reader. 5.6 Windows detached no-inherit (harness spawn rides broker, not detached_no_inherit —
  confirm broker path is clean). 2.4 gen_start fresh on cold-start (don't rehydrate). 4.10
  registry eviction (perch registration is daemon-authoritative).

## Build order
1. Fill the bind/register seam section from the trace.
2. Daemon harness-spawn fn + its unit test (compile+test in isolation).
3. `EndpointCmd::Run` + `cmd_endpoint_run` (wire daemon fn; `--start` only first).
4. `Cmd::Rc` + `cmd_rc` pump + its unit test (one-path assertion).
5. Wire `--attach`/`--view` of `endpoint run` into the rc pump.
6. `traceable-reqs check` EXIT=0; activate stages doc+impl+unit; commit.
7. Ping doyle for W1 gate (int E2E + cross-subnet proof at the gate).


Plan is well-traced (seams at file:line, hazards honored, one-path baked, test split correct). Validating + signing off:


cd 'C:\Users\decid\Documents\projects\spt-core'; "$OWL" send todlando doyle <<'EOF'
W1 GATE-PLAN VALIDATED. Read M12-W1-PLAN.md end to end. Sign-off:

1) Registration (spawn-first, self-register on bind) — APPROVED. Matches the post-spawn seam; broker-held⇒survives-detach by construction is exactly right.
2) ID plumbing Verdict A (argv {id}, no SpawnReq change) — APPROVED. Keeps broker IPC stable; correct call.
4) rc one-path — APPROVED, and good that T1.2.3 asserts it in the unit test.
5) Test split (unit now / int at W-final) — APPROVED. Per-wave activation correct.

3) cwd — MY VERDICT: defer past the W1 gate is fine (cwd isn't needed to PROVE bringup+attach). BUT cwd is NOT optional for M12 — make it a tracked REQ now (REQ-HOST-RUN-2 cwd/project), must land before the M12 gate. Reasons: (a) it's in the documented spawn-session seam ("cwd/project"); (b) the real consumer is Claude Code, which is PROJECT-SCOPED — broker-inherited cwd = daemon's cwd, not the user's project → wrong .claude, wrong session history, wrong digest source. `cc <id>` at a project root MUST land CC in that project. Caveat: cwd DOES need the SpawnReq wire change you avoided for id (broker spawns the PTY, cwd must reach it) — additive field, N-1 safe, do it deliberately. So: W1 broker-inherited cwd = proof shortcut only; don't close M12 without real cwd.

Two minor follow-up flags (NOT W1 blockers):
- PTY resize: you set initial real dims (good) — but an interactive CC session needs terminal-resize events to flow through the attach pump too. Track for a later W.
- Detach keybind (T1.2.5): define it explicitly + ensure it can't collide with CC passthrough input (legacy capsule used a ctrl+b prefix). Document it.

Net: proceed to finish W1. cwd → new tracked REQ. Ping me at the W1 gate for the int E2E + cross-subnet proof. — doyle

**Sign-off:** decisions 1, 2, 4, 5 approved. On #3 (cwd) — defer past W1 *proof* OK, but ruled it a **tracked REQ (cwd/project) that must land before the M12 gate**: CC is project-scoped, so broker-inherited cwd = wrong project (wrong `.claude`/history/digest source); `cc <id>` must land CC in the project. Noted it needs the SpawnReq wire change he avoided for id (additive, N-1 safe). Plus two minor non-blocking flags: PTY resize propagation, and define the detach keybind (collision-safe).

</task-notification>


todlando flagged a non-blocking empirical risk: loopback self-dial (one broker as both dialer+acceptor) is untested same-node, "possibly buggy." His mitigation = fall back to an in-process stream pair feeding the **same** `serve_attach` pump. That preserves my one-path mandate — worth confirming so he proceeds without doubt:


cd 'C:\Users\decid\Documents\projects\spt-core'; "$OWL" send todlando doyle <<'EOF'
Fallback APPROVED — and it does NOT violate the one-path mandate. The invariant is "one serve_attach PUMP path," not "one transport." Loopback QUIC vs an in-process stream pair is just what rides under the stream; if both feed the same serve_attach pump, cross-node correctness still IS local correctness. So:

- Try loopback self-dial first (your "literally one path" — cleanest if it works).
- If same-node double-registration misbehaves, the in-process stream pair is the RIGHT fallback, not a compromise. Don't twist QUIC-to-self to force it — for local you don't need crypto/handshake anyway.
- Just assert in the test that BOTH transports land in the same pump (the one-path assertion lives at the pump, not the dialer).

crossterm for raw mode = good, consistent with W2 ratatui. Proceed. Verdict at the gate. — doyle

`SENT:todlando` ✓. Affirmed: the one-path invariant lives at the `serve_attach` pump, not the transport — so the in-process-stream-pair fallback is a legit equal, not a compromise. Told him to assert both transports land in the same pump, and not to force QUIC-to-self if it fights.

Real decision + empirical finding. Loopback self-dial is *impossible* (iroh refuses self-connect, pinned green test) — option A dead. Cross-node rc already done + green. Only LOCAL attach needs a transport. My call on both his questions:


cd 'C:\Users\decid\Documents\projects\spt-core'; "$OWL" send todlando doyle <<'EOF'
Good empirical kill on self-dial — pinning it as a green test is the right move (documents WHY local can't ride literal self-QUIC).

DECISION 1 — B1, not B2. Local attach is `cc`'s dominant, everyday path — it MUST be rock-solid, and B1 makes it ride the byte-identical pump+serve path, fully covered by the proven cross-node tests. B2 reintroduces exactly the lesser-tested local branch I warned against (local skips serve_attach's net-stream handling → can silently diverge from cross-node). The broker-layer cost of B1 is justified precisely because local is the hot path. B1 is the literal honoring of "cross-node correctness IS local correctness."

DECISION 2 — scope B1 as a tight W1.5, NOT in W1. Reasons: (a) cross-node attach + endpoint-run bringup + the pump are built+green — GATE W1 NOW to bank them; bringup is verifiable at the W1 gate via cross-node attach to the spawned PTY (no local needed to prove the spawn). (b) B1 is a sensitive broker-layer addition (new in-process loopback conn + stream routing + dispatch wiring) — it deserves its own focused task + gate in the 6.7 zone, not bundled into an otherwise-done W1. (c) Local still lands immediately after, before M12 closes, so the `cc` local-first requirement holds.

So: W1 gate = bringup + cross-node rc + pump (green). REQ-RC-1 local facet = W1.5 int evidence (per-wave activation: cross-node int at W1 gate, local int at W1.5). Keep the "both transports → one pump" assertion in W1.5.
