M12 W1 (spt-hosted harness bringup + `spt rc` PTY attach) — doyle handed execution to todlando 2026-06-14. Full spec: `M12-PLAN.md` + `M12-W1-PLAN.md` (durable build plan, resumable).

**Built + green:**
- Daemon `spt-daemon/src/harnesshost.rs`: `prepare_harness_spawn` (validate kind=harness + fill `[session.self]` template) + `launch_harness_brokered_in` (spawn into broker PTY via `spawn_session_pid`, mirrors `shellhost::launch_shell_brokered_in`) + `mint_session_id`. 3 unit tests.
- `spt/src/rc.rs`: operator attach pump (single-Brain main thread + stdin reader thread→mpsc, `cold_start_pump` Split carrier for bounded reads, seq-dedup, ctrl-b detach state machine). 3 unit tests.
- cli.rs: `EndpointCmd::Run` + `cmd_endpoint_run`; top-level `Cmd::Rc`; crossterm dep added.
- REQs registered: REQ-HOST-RUN-1 (spawn), REQ-RC-1 (attach), REQ-HOST-RUN-2 (project cwd — doyle-mandated, must land before M12 gate; W1 ships broker-inherited cwd as proof-shortcut only).

**KEY DECISIONS (doyle-validated):** spawn-first (harness self-registers its perch on bind via `api/startup.rs establish_perch`, no daemon pre-register); id rides argv via `{id}` template (NO SpawnReq wire change); one-pump invariant = transport swappable under one `serve_attach` pump.

**BLOCKER RESOLVED (doyle ruling 2026-06-14):** loopback self-dial IMPOSSIBLE (iroh refuses `net_dial(own_addr)`, pinned green test). doyle picked **B1 (broker in-process loopback-conn — local rides byte-identical pump+serve path, covered by cross-node tests; B2's pump-branch rejected as the lesser-tested local path warned against), scoped as a tight W1.5** (NOT in W1). Rationale: cross-node attach + endpoint-run bringup + pump are built+green → gate W1 NOW (bringup verifiable via cross-node attach to the spawned PTY); B1 is a sensitive broker-layer addition (6.7 zone) deserving its own focused task+gate; local lands W1.5 before M12 close. One-pump assertion (both transports → one pump) kept in W1.5.

**REQ-RC-1 split:** cross-node int evidence at W1 gate; local int evidence at W1.5 (per-wave activation).

**W1 GATE: PASS (doyle 2026-06-14).** Independently verified: traceable-reqs check reproduced (196 complete / 0 findings; REQ-HOST-RUN-1 + REQ-RC-1 impl+unit+int, REQ-HOST-RUN-2 []); int test `attach.rs:217` inspected — real `launch_harness_brokered_in` spawns [session.self] into broker-A PTY, B attaches cross-node, HOSTED_OK round-trips, detach→Detached+survives, origin=handshake-identity (KH 7.5); self-dial-refused pin genuine. Trusted reported full-suite (46 bins/0) + clippy -D. **UNCOMMITTED** (awaiting operator).

**W1.5 GATE PASS (doyle 2026-06-14, independently verified — read shared helper + both int tests + reproduced trace).** B1 broker loopback-conn done (design in `M12-W1.5-PLAN.md` "Crystallized design"). Transport seam = `tokio::io::duplex` (ONE full-duplex pair wires a whole operator↔peer stream); only the leaf send/recv become enums (`SendHalf`/`RecvHalf`), so StreamLog/subscribe/send_stream/read-pump are byte-identical across QUIC + loopback. `nethost::dial_loopback` = reused SINGLETON, `remote_id_hex` = own-node id; `open_stream` on a `ConnKind::Loopback` mints the cross-wired PAIR (operator row + peer row); peer row (initiated_locally=false, own origin) → dispatch loop → serve_attach. Explicit `net-dial-loopback` frame (brain.net_dial_loopback + broker.dispatch_net_dial_loopback) — net_dial untouched. access same-node short-circuit (access.rs:89) Allows own-node → NO access change. rc.rs ONE self-dial line swapped → net_dial_loopback. ONE-PUMP PROOF by construction: shared `attach_drive_detach` helper called by BOTH cross-node `remote_attach_drives_a_real_pty_cross_daemon` AND new `local_attach_via_loopback_conn_rides_the_same_pump` — diverge only in conn acquisition + expected_origin. EVIDENCE: attach int 6/6 + new nethost unit `loopback_conn_is_a_reused_singleton_that_cross_wires_a_stream_pair`; full spt+spt-daemon suite **498 passed/0 failed**; clippy -D EXIT=0; traceable EXIT=0 (REQ-RC-1 [OK] impl+unit+int). **UNCOMMITTED** (operator-gated, m12-w1-bringup-rc).

**REQ-HOST-RUN-2 DONE (todlando 2026-06-14) — gate pinged doyle, verdict pending.** Additive `SpawnReq.cwd: Option<String>` (serde default+skip_if_none, N-1 safe) → spt-term `PtySession::spawn_program_in(cwd)` (portable-pty CommandBuilder::cwd; `spawn_program` delegates None) → broker `dispatch_spawn` honors `req.cwd` → harnesshost `launch_harness_brokered_in(.., cwd: Option<&str>)` → cli `cmd_endpoint_run` derives PROJECT cwd from `std::env::current_dir()` (None-fallback, never aborts). Shells unchanged (cwd:None, out of scope). 17 SpawnReq literals patched +cwd:None. EVIDENCE: unit `spawn_program_in_lands_the_child_in_the_requested_cwd` (spt-term, unix-gated like capture test); int `broker_spawns_the_pty_child_in_the_requested_cwd` (CROSS-PLATFORM, passes Windows — wire→broker→PTY cwd e2e); full suite **527/0**; clippy EXIT=0; traceable EXIT=0 (REQ-HOST-RUN-2 [OK] impl+unit+int). UNCOMMITTED.

**NEXT (after gate verdict + operator call):** full-fat M12 remaining waves — W2 picker → W3 manifest → W4 subnet QR → W5 whoami. W1.x bringup+rc foundation now complete (spt-hosted bringup + cross-node + LOCAL rc + project cwd). Commit only when user asks (not on default branch unprompted). See [[traceable-per-wave-activation]], [[pump-ipc-deadline-fix]], [[spt-claude-code-next]] (perri waits on M12 gate).

feat(rc,endpoint): M12 W1.5 broker loopback-conn + REQ-HOST-RUN-2 project cwd

W1.5 (REQ-RC-1 local face): LOCAL `spt rc` now rides the byte-identical
serve_attach pump via a broker in-process loopback connection (doyle ruling B1)
— a QUIC self-dial is refused by iroh. nethost gains ConnKind{Quic,Loopback} +
SendHalf/RecvHalf enums; one tokio::io::duplex wires an operator<->peer stream
pair, both feeding the SAME StreamLog/subscribe/read-pump (the one-pump
invariant lives at the transport leaf only). dial_loopback mints a reused
singleton whose origin is this node's own id (gates same-node, access.rs:89
short-circuit). Explicit net-dial-loopback frame; net_dial stays pristine.
rc.rs swaps its one self-dial line. One-pump proven by construction: a shared
attach_drive_detach helper drives BOTH the cross-node and the new local int
tests, diverging only in conn acquisition + expected origin.

REQ-HOST-RUN-2: additive SpawnReq.cwd (serde default + skip_if_none, N-1 safe)
threads through PtySession::spawn_program_in (portable-pty CommandBuilder cwd)
-> broker dispatch_spawn -> harnesshost -> cli, which derives the PROJECT cwd
from std::env::current_dir(). The spt-hosted harness PTY lands in the user's
project root, not the daemon's (the consumer reads .claude/history/digest
relative to cwd). Shells unchanged (cwd: None).

Evidence: attach int (local loopback + project cwd) + nethost & spt-term units;
full spt+spt-daemon+spt-term suite 527 passed / 0 failed; clippy -D warnings
clean; traceable REQ-RC-1 + REQ-HOST-RUN-2 [OK] impl+unit+int.

W3 = T3.1 (file-backed `[strings]`) + T3.2 (`<adapter>:<profile>` fallback targets). Touches manifest schema + adapter resolution → warrants a JIT plan + doyle design-check before building. Investigate current state first — manifest `[strings]`, profile overlay, fallback:

Need T3.2's fallback mechanism + confirm no existing aux file location. Investigate fallback field + CONTEXT "ccs" wording:


Bash

cd "C:\Users\decid\Documents\projects\spt-core"; echo "=== fallback in runtime ==="; grep -rniE "fallback|fallback_adapter|fall_back" crates/spt-runtime/src/*.rs | grep -iv "spt-core fallback\|relay fallback\|degrade" | head -25; echo "=== CONTEXT ccs/fallback wording ==="; grep -niE "ccs|fallback|its own adapter" CONTEXT.md | head -20

Find fallback mechanism + CONTEXT ccs wording


=== fallback in runtime ===
crates/spt-runtime/src/manifest.rs:314:/// fallback for a log-less adapter (which declares no `[digest]` at all).
crates/spt-runtime/src/manifest.rs:318:/// spt-core ships fallback defaults ([`spt_term::DigestConfig`]) when absent. The
=== CONTEXT ccs/fallback wording ===
135:- **Hook output capability is declared per harness-event** (`can_inject`). CC's Stop hook cannot inject context — that single fact drives the echo-gate sentinel + relay fallback. The manifest expresses it so spt-core knows when to fall back.
137:- **Cross-adapter fallback** is a **node-wide setting**, not a manifest field: if a Psyche/echo invocation under one adapter is rate-limited, spt-core falls back to another adapter (e.g. `ccs`, now its own adapter — not a binary-swap). Adapter-agnostic IDs make this safe; an endpoint's Psyche may run under a fallback adapter temporarily.
342:- **Adapter-declared extraction (post-M9 milestone — reverses M9's "no manifest seam"):** M9 retired the PTY-parse engine and made the digest an on-demand projection over a published `{role,text,tool}` contract carried in `[history]`. That under-served real adapters: one normalizer cannot serve echo (opaque) and the digest (contract) at once, and a contract mismatch failed **silently**. So the digest gets its **own `[digest]` manifest seam** — an **imperative extractor** the adapter declares (its native log → the `{role, text, tool, ts}` contract; reads the same source files as `[history]` by default, own-source escape hatch), with **`api digest-entry`** as the always-available push fallback. **No declarative DSL** (anyone who could conform to a fixed format could as easily push or write the extractor). **`spt adapter digest-proof`** lets an author validate their extractor's output; the daemon surfaces the same skip-diagnostics at runtime. The PTY-parse engine stays retired. (Successor to ADR-0008.)
354:Out of the box, WAN connection setup and the ~30% relay-fallback path route through relay servers operated by **n0.computer** (Iroh's authors) — free, accountless, the silent default that makes zero-config WAN work. This is a soft, metadata-only, escapable runtime dependency:
355:- It is operational, not a code dependency. n0 relays being unavailable degrades initial connection setup and the relay-fallback case; already-established direct connections are unaffected.
517:Layering (bottom → top): `spt-proto` (wire envelope grammar, endpoint types, message framing, Ed25519 identity types, typed+binary payload schema — pure types, no I/O) → `spt-store` (spool, perch layout, trust store, registry persistence) → `spt-msg` (delivery TCP+spool-fallback, routing, send/ring) → `spt-net` (Iroh, mDNS, SPAKE2/TOTP pairing, subnet-registry distribution; `net` feature-flagged) and `spt-term` (session-surface trait, PTY impl, broker) and `spt-runtime` (`AgentRuntime` trait, `ManifestRuntime`, manifest schema) → `spt-live` (Psyche/pulse/commune/signoff) → `spt-daemon` (the brain: ties all, hosts broker, update orchestration, instance registry) → `spt` (the `spt.exe` binary; thin CLI).
640:**Daemon lifecycle:** registered as a systemd user service (Linux) / Windows service or scheduled task for the always-on guarantee, with `spt api`-triggered auto-start as the fallback (above). The first network bind triggers the OS firewall prompt here.
642:**What "installed" comprises:** the `spt` binary + the broker + the `$SPT_HOME` root (holds `node.key`, trust store, registry, spools, in-memory-seed fallback state). **First run is idempotent + interactive-optional:** generates the node identity and starts the daemon unattended; pairing (and subnet naming) is a separate explicit step.


T3.2 clarified (CONTEXT:137): cross-adapter fallback is a node-wide **setting** (not manifest) currently targeting a bare adapter_name → extend to `<adapter>:<profile>`. Locate that setting:


cd "C:\Users\decid\Documents\projects\spt-core"; grep -rniE "fallback_adapter|fallback.adapter|adapter.fallback|cross.adapter|rate.?limit.*adapter|fallback.*ccs" crates/spt-daemon/src crates/spt-live/src 2>/dev/null | head -20; echo "=== settings/config with adapter ==="; grep -rliE "fallback" crates/spt-daemon/src crates/spt-live/src 2>/dev/null | head

W3 needs design rulings (file-pointer syntax, aux storage location, and T3.2 scope — the node-wide fallback setting doesn't appear to exist yet). Per doyle's offer, I'll write a W3 JIT plan + ring him for the design check before building. Write the plan:


Write

# M12 Wave 3 — adapter manifest enhancements (JIT plan)

> todlando 2026-06-14, post W1.5+REQ-HOST-RUN-2 gate (both PASS, committed 0c687fe). doyle
> ordered W3 FIRST (most directly unblocks spt-claude-code). DESIGN-CHECK PENDING with doyle
> before building (open questions below). Build only after his ruling.

## Scope (M12-PLAN.md Wave 3)
- **T3.1** File-backed adapter `[strings]`: a `[strings]` entry may point to a FILE; standardized
  per-adapter auxiliary file-storage location (verify none exists). Resolution still rides the
  leaf-replace profile overlay. Unblocks spt-claude-code skill-instruction + hint bodies without
  manifest bloat.
- **T3.2** Cross-adapter fallback targets `<adapter>:<profile>` (not just bare adapter_name);
  reconcile CONTEXT.md "ccs, its own adapter" wording.

## What exists today (investigation)
- `Manifest.strings: toml::Table` — opaque KV, dot-path readable via `spt adapter get-string`,
  rides leaf-replace profile overlay (REQ-MANIFEST-3). manifest.rs:66-75.
- Local profiles: `adapters/<adapter>/profiles/<profile>.toml` (REQ-MANIFEST-2). `<adapter>:<profile>`
  composite address already parsed by `registry::resolve_option`.
- **No per-adapter aux/data file-storage location exists** beyond `profiles/` (confirmed).
- **No node-wide cross-adapter fallback SETTING is implemented yet** — CONTEXT.md:137 describes it
  ("node-wide setting, not a manifest field; falls back to another adapter e.g. ccs") but no
  `fallback_adapter` config/consumer found in spt-daemon/spt-live. T3.2 scope hinges on this.

## Open design questions for doyle
**T3.1**
1. File-pointer syntax for a `[strings]` entry. Proposal: inline table `key = { file = "rel/path" }`
   (explicit, typed, leaf-replace-overlayable) vs a `@file:` sentinel string vs a `[strings.files]`
   sub-table. Recommend the inline-table form.
2. Standardized aux file-storage location. Proposal: `adapters/<adapter>/strings/` (sibling of
   `profiles/`), file paths resolved relative to it; a local profile may override the pointer or
   inline the value (leaf-replace). Confirm location + shipped-vs-local override semantics.
3. Read timing. Proposal: validate-exists at registration; read LAZILY at `get-string` (file edits
   reflect without re-register); skip-diagnostics (no silent drop) on missing/unreadable, matching
   the `[digest]` skip-diagnostics stance.

**T3.2**
4. The node-wide fallback setting appears absent. Is T3.2 = (a) ONLY make the fallback TARGET
   resolve through `resolve_option` (adapter:profile-aware) wherever a fallback target string is
   read + reconcile CONTEXT.md wording (deferring the full fallback-invocation wiring to the
   consuming milestone), or (b) also establish the node-wide setting + its consumer now? Recommend
   (a) — minimal, contract-only, unblocks spt-claude-code's addressing without speculative wiring.

## Tasks (pending doyle ruling — shapes may shift)
- **T3.1a** New REQ (e.g. REQ-MANIFEST-5) in traceable-reqs.toml first. Manifest: file-pointer
  parse + the aux-dir resolver + lazy read at get-string + register-time validate + skip-diag.
- **T3.1b** Unit (parse + overlay leaf-replace of a file pointer) + int (get-string reads the file;
  a profile overrides it).
- **T3.2a** Resolve fallback target via `resolve_option` (adapter:profile); CONTEXT.md reconcile.
  REQ id per doyle's scope ruling.
- Activate stages as evidence lands. Full suite + clippy -D + traceable EXIT=0. W3 gate (doyle).

## Notes
- Manifest schema = ADR-0001 wire/contract territory: copy-verbatim stable formats, additive +
  N-1-safe, regen `manifest.schema.json` (doc generation is CI-gated against drift).
- UNCOMMITTED building until operator calls a commit (they chose commit-then-continue for W1.5+HR2).

$OWL ring doyle todlando <<'EOF'
W3 DESIGN-CHECK before building (you offered). Full JIT plan = M12-W3-PLAN.md. Investigation done; need your rulings on 4 questions — 2 are real scope forks.

CONTEXT FOUND:
- strings = toml::Table opaque KV, get-string dot-path, rides leaf-replace overlay (REQ-MANIFEST-3).
- Local profiles at adapters/<adapter>/profiles/; `<adapter>:<profile>` already parsed by resolve_option.
- NO per-adapter aux file-storage location exists (only profiles/).
- NO node-wide cross-adapter fallback SETTING is implemented — CONTEXT.md:137 only DESCRIBES it ("node-wide setting, falls back to e.g. ccs"). T3.2 scope depends on this.

T3.1 (file-backed strings):
Q1 syntax — propose inline table `key = { file = "rel/path" }` (typed, leaf-replace-overlayable) over a `@file:` sentinel or `[strings.files]` subtable. OK?
Q2 aux location — propose `adapters/<adapter>/strings/` (sibling of profiles/), paths relative to it; a profile may override the pointer or inline the value. Confirm location + shipped-vs-local override.
Q3 read timing — propose validate-at-register + LAZY read at get-string (file edits reflect w/o re-register) + skip-diagnostics on missing (mirrors [digest] stance). OK?

T3.2 (adapter:profile fallback) — THE SCOPE FORK:
Q4 — fallback setting appears ABSENT. Is T3.2 = (a) ONLY make the fallback TARGET resolve via resolve_option (adapter:profile-aware) wherever read + reconcile CONTEXT.md wording, deferring full fallback-invocation wiring to the consuming milestone; OR (b) ALSO establish the node-wide setting + consumer now? I recommend (a) — contract-only, unblocks spt-claude-code addressing, no speculative wiring. Your call.

HOLDING build until your rulings. New REQ id(s) to register first per traceability — suggest REQ-MANIFEST-5 (T3.1); T3.2 id pending your scope ruling.

- Daemon `spt-daemon/src/harnesshost.rs`: `prepare_harness_spawn` (validate kind=harness + fill `[session.self]` template) + `launch_harness_brokered_in` (spawn into broker PTY via `spawn_session_pid`, mirrors `shellhost::launch_shell_brokered_in`) + `mint_session_id`. 3 unit tests.
- `spt/src/rc.rs`: operator attach pump (single-Brain main thread + stdin reader thread→mpsc, `cold_start_pump` Split carrier for bounded reads, seq-dedup, ctrl-b detach state machine). 3 unit tests.
- cli.rs: `EndpointCmd::Run` + `cmd_endpoint_run`; top-level `Cmd::Rc`; crossterm dep added.
- REQs registered: REQ-HOST-RUN-1 (spawn), REQ-RC-1 (attach), REQ-HOST-RUN-2 (project cwd — doyle-mandated, must land before M12 gate; W1 ships broker-inherited cwd as proof-shortcut only).

**KEY DECISIONS (doyle-validated):** spawn-first (harness self-registers its perch on bind via `api/startup.rs establish_perch`, no daemon pre-register); id rides argv via `{id}` template (NO SpawnReq wire change); one-pump invariant = transport swappable under one `serve_attach` pump.

**BLOCKER RESOLVED (doyle ruling 2026-06-14):** loopback self-dial IMPOSSIBLE (iroh refuses `net_dial(own_addr)`, pinned green test). doyle picked **B1 (broker in-process loopback-conn — local rides byte-identical pump+serve path, covered by cross-node tests; B2's pump-branch rejected as the lesser-tested local path warned against), scoped as a tight W1.5** (NOT in W1). Rationale: cross-node attach + endpoint-run bringup + pump are built+green → gate W1 NOW (bringup verifiable via cross-node attach to the spawned PTY); B1 is a sensitive broker-layer addition (6.7 zone) deserving its own focused task+gate; local lands W1.5 before M12 close. One-pump assertion (both transports → one pump) kept in W1.5.

**REQ-RC-1 split:** cross-node int evidence at W1 gate; local int evidence at W1.5 (per-wave activation).

**W1 GATE: PASS (doyle 2026-06-14).** Independently verified: traceable-reqs check reproduced (196 complete / 0 findings; REQ-HOST-RUN-1 + REQ-RC-1 impl+unit+int, REQ-HOST-RUN-2 []); int test `attach.rs:217` inspected — real `launch_harness_brokered_in` spawns [session.self] into broker-A PTY, B attaches cross-node, HOSTED_OK round-trips, detach→Detached+survives, origin=handshake-identity (KH 7.5); self-dial-refused pin genuine. Trusted reported full-suite (46 bins/0) + clippy -D. **UNCOMMITTED** (awaiting operator).

**W1.5 GATE PASS (doyle 2026-06-14, independently verified — read shared helper + both int tests + reproduced trace).** B1 broker loopback-conn done (design in `M12-W1.5-PLAN.md` "Crystallized design"). Transport seam = `tokio::io::duplex` (ONE full-duplex pair wires a whole operator↔peer stream); only the leaf send/recv become enums (`SendHalf`/`RecvHalf`), so StreamLog/subscribe/send_stream/read-pump are byte-identical across QUIC + loopback. `nethost::dial_loopback` = reused SINGLETON, `remote_id_hex` = own-node id; `open_stream` on a `ConnKind::Loopback` mints the cross-wired PAIR (operator row + peer row); peer row (initiated_locally=false, own origin) → dispatch loop → serve_attach. Explicit `net-dial-loopback` frame (brain.net_dial_loopback + broker.dispatch_net_dial_loopback) — net_dial untouched. access same-node short-circuit (access.rs:89) Allows own-node → NO access change. rc.rs ONE self-dial line swapped → net_dial_loopback. ONE-PUMP PROOF by construction: shared `attach_drive_detach` helper called by BOTH cross-node `remote_attach_drives_a_real_pty_cross_daemon` AND new `local_attach_via_loopback_conn_rides_the_same_pump` — diverge only in conn acquisition + expected_origin. EVIDENCE: attach int 6/6 + new nethost unit `loopback_conn_is_a_reused_singleton_that_cross_wires_a_stream_pair`; full spt+spt-daemon suite **498 passed/0 failed**; clippy -D EXIT=0; traceable EXIT=0 (REQ-RC-1 [OK] impl+unit+int). **UNCOMMITTED** (operator-gated, m12-w1-bringup-rc).

**REQ-HOST-RUN-2 GATE PASS (doyle 2026-06-14) — verified end-to-end.** doyle: "the confirmed-missing gating foundation is DONE + gated; the hard part of M12 is done." CONTINUE-vs-CHECKPOINT (W2-W5) routed to OPERATOR; HOLD building until operator relays. doyle suggested order if continue: **W3 first** (file-backed strings + adapter:profile fallback — most directly unblocks spt-claude-code) → then W2/W4/W5. Additive `SpawnReq.cwd: Option<String>` (serde default+skip_if_none, N-1 safe) → spt-term `PtySession::spawn_program_in(cwd)` (portable-pty CommandBuilder::cwd; `spawn_program` delegates None) → broker `dispatch_spawn` honors `req.cwd` → harnesshost `launch_harness_brokered_in(.., cwd: Option<&str>)` → cli `cmd_endpoint_run` derives PROJECT cwd from `std::env::current_dir()` (None-fallback, never aborts). Shells unchanged (cwd:None, out of scope). 17 SpawnReq literals patched +cwd:None. EVIDENCE: unit `spawn_program_in_lands_the_child_in_the_requested_cwd` (spt-term, unix-gated like capture test); int `broker_spawns_the_pty_child_in_the_requested_cwd` (CROSS-PLATFORM, passes Windows — wire→broker→PTY cwd e2e); full suite **527/0**; clippy EXIT=0; traceable EXIT=0 (REQ-HOST-RUN-2 [OK] impl+unit+int). UNCOMMITTED.

**NEXT (after gate verdict + operator call):** full-fat M12 remaining waves — W2 picker → W3 manifest → W4 subnet QR → W5 whoami. W1.x bringup+rc foundation now complete (spt-hosted bringup + cross-node + LOCAL rc + project cwd). Commit only when user asks (not on default branch unprompted). See [[traceable-per-wave-activation]], [[pump-ipc-deadline-fix]], [[spt-claude-code-next]] (perri waits on M12 gate).

+**NOW: W3 in DESIGN-CHECK with doyle (build HELD).** Operator said CONTINUE; doyle ordered W3 first (unblocks spt-claude-code). Plan = `M12-W3-PLAN.md`. W3 = T3.1 file-backed `[strings]` (entry points to a FILE; aux storage location) + T3.2 cross-adapter fallback targets `<adapter>:<profile>`. KEY FINDINGS: no per-adapter aux file location exists (only profiles/); **no node-wide cross-adapter fallback SETTING implemented** (CONTEXT.md:137 only describes it) → T3.2 is a SCOPE FORK ringed to doyle (recommend contract-only resolution + CONTEXT reconcile, defer fallback-invocation wiring). Proposals pending doyle: inline-table `key={file=".."}` syntax, `adapters/<adapter>/strings/` aux dir, validate-at-register + lazy-read + skip-diag, new REQ-MANIFEST-5. Remaining after W3: W2 picker → W4 subnet QR → W5 whoami. Commit only when operator asks.

**Committed `0c687fe`** (W1.5 + REQ-HOST-RUN-2, 24 files). W1.x foundation done + gated.

Continuing to W3 per doyle's order. W3 touches the manifest contract + has a real scope fork, so I wrote `M12-W3-PLAN.md` and ringed doyle for design rulings before building:

- **T3.1 file-backed `[strings]`** — proposed: inline-table `key = { file = "..." }`, aux dir `adapters/<adapter>/strings/`, validate-at-register + lazy-read + skip-diag.
- **T3.2 `<adapter>:<profile>` fallback** — found the node-wide fallback setting **doesn't exist yet** (CONTEXT only describes it) → scope fork: contract-only resolution now (recommended) vs build the full setting+consumer. doyle's call.

Build **held** until doyle's rulings (incoming via poll). Memory updated.

doyle rulings in — all 4 answered, build + gate. Key adds: Q1 reserve `{file=...}` as pointer-only; Q2 two guards (containment: reject `..`; update-safety: local-profile pointers resolve to the user-owned profile dir, not adapter-shipped `strings/`); Q4 contract-only (resolve_option everywhere + CONTEXT reconcile). REQs: MANIFEST-5 (T3.1 doc+impl+unit), MANIFEST-6 (T3.2 doc+unit).

W3 rulings locked — building now.
Q1 inline-table `{file="rel"}` = pointer-only (document: a value-position table with a `file` key can't double as data).
Q2 `adapters/<adapter>/strings/` + TWO guards: (i) containment — resolved path stays inside the dir, reject `..`; (ii) update-safety — LOCAL-profile pointers resolve to the user-owned profile dir, NOT adapter-shipped strings/ (else updates clobber); shipped→strings/, local→local-owned-or-inline.
Q3 validate-at-register + lazy-read + skip-diag.
Q4 (a) contract-only — resolve_option is THE resolver at every adapter-option read site + CONTEXT.md:137 reconcile ("ccs is a profile; cross-adapter fallback may target <adapter>:<profile>"); defer invocation. If resolve_option already covers read sites, T3.2 = doc reconcile + a unit, no manufactured impl.
