Confirmed: **b90820c killed the 60s flash, verified clean — the reported bug is fixed.** Remaining work = close the residual so hazard 5.8 is a real invariant. You greenlit hardening `command_for`.

Plan (Phase 5): centralize `CREATE_NO_WINDOW` in `ManifestRuntime::command_for` — one seam covering both `spawn_session` (notif pump + psyche) and `run_bounded_stdin` (echo/turn). These are all detached/bounded non-interactive spawns; the interactive PTY goes through the broker/ConPTY, not `command_for` — so it's safe.

Apply the fix:

/diagnose the pc crashed. before it died, you were in the middle of debugging an issue where every 60 seconds, a running spt daemon spawned 2 empty windows in short succession. each window only lasted…


Both `bounded_run_captures_success` (478) and `spawn_session_detached_returns_pid` (511) now exercise the flagged `command_for` path on Windows — they ARE the error-87 regression coverage. Tag them.

Command running in background with ID: b3uc7wchn. Output is being written to: C:\Users\decid\AppData\Local\Temp\claude\C--Users-decid-Documents-projects-spt-core\eb9effe4-c6da-4e0e-9c86-b5e67ffd4772\tasks\b3uc7wchn.output. You will be notified when it completes. To check interim output, use Read on that file path.


Fix applied. While tests run, the diagnostic post-mortem (Phase 6):

**Root cause (confirmed):** console-subsystem children of the console-less DETACHED daemon allocate a visible conhost; null/piped stdio doesn't suppress it. The 60s/2-window symptom = the sync pump's `for-each-ref` + `rev-parse` git pair — already fixed + verified in `b90820c`.

**What b90820c missed (now closed):** it patched 4 named call sites but left `ManifestRuntime::command_for`, the shared builder behind `spawn_session` (notif pump, psyche) and `run_bounded_stdin` (echo, turn). Putting the flag in the *builder* instead of per-call-site means the hazard 5.8 invariant now holds **by construction** — no future spawn path can forget it.

**Prevention:** this bug recurred because the flag was per-call-site, not centralized — exactly the "not yet an invariant" the commit flagged. Centralizing in the builder is the structural fix.

Waiting on `cargo test -p spt-runtime` + `traceable-reqs check`.

Green. 26/26 pass — including the two flagged-spawn tests **on Windows** (`spawn_session_detached_returns_pid`, `bounded_run_captures_success`), which is the error-87 regression class cleared on the real platform. `REQ-HAZARD-CHILD-CONSOLE-FLASH` = `[OK]` (+doc +impl +unit).

## Done — diagnosis closed

**Reported bug (60s / 2 windows): already fixed in `b90820c`, verified clean by you.** Root cause = sync pump's `for-each-ref`+`rev-parse` git pair spawned windowless-less from the console-less daemon.

**Residual I closed this session:** b90820c patched 4 call sites but missed `ManifestRuntime::command_for` — the shared builder behind the notif pump (`spawn_session`) and live-agent echo/turn (`run_bounded_stdin`). Same bug class, latent on Windows.

Changes (isolated, on top of the existing WIP tree):
- `runtime.rs` — `CREATE_NO_WINDOW` in `command_for` (one builder, covers both spawn legs)
- `runtime.rs` — `[unit->REQ-HAZARD-CHILD-CONSOLE-FLASH]` on the two existing flag-exercising tests
- `KNOWN-HAZARDS.md` — 5.8 mapping now lists the builder

**Invariant now holds by construction** — flag in the builder, not per call site. That's the structural reason the bug can't recur on a forgotten spawn path.

No DEBUG instrumentation or throwaway files to clean up (recovery was read-only). **Not committed** — your tree has the big cargo-fmt churn + REQ-UPD-6 debug-rollout WIP mixed in; my 3-file change sits on top. Say the word and I stage just these for a focused commit, or fold into the hazard sweep.

fix(runtime): CREATE_NO_WINDOW in command_for — close the KH 5.8 residual

b90820c fixed the reported field bug (the 60s sync pump flashed two blank
windows/min from spt-store::gitrun::run_git) plus taskkill and the free
run_bounded_command, and was verified clean live. But it patched named call
sites, not the shared builder: ManifestRuntime::command_for set no
creation_flags, so the two spawns that route through it still flashed on
Windows — spawn_session (the notif pump spawn_notif_command, live-agent
psyche) and run_bounded_stdin (live-agent echo/turn).

Set CREATE_NO_WINDOW once in command_for so every ManifestRuntime spawn
inherits it by construction — the KNOWN-HAZARDS 5.8 invariant ("every
console child of the console-less daemon is windowless") now holds without
relying on each call site to remember. The flag belongs in the builder, not
the leaves; per-call-site coverage is exactly why this recurred.

Coverage: the two existing tests that exercise the flagged path on Windows
(spawn_session_detached_returns_pid, bounded_run_captures_success) carry the
[unit->REQ-HAZARD-CHILD-CONSOLE-FLASH] tag — they prove the flag does not
break the spawn (the error-87 flag-combo regression class, cf. c7e7d9e).
Window-absence itself stays unobservable from a consoled test runner (5.8
test-seam caveat); that half was verified live by process-watch.

KNOWN-HAZARDS 5.8 mapping updated to list command_for as a covered site.

## Status Update
Post-diagnostic session identified residual windows-bug exposure in `b90820c` "CREATE_NO_WINDOW" fix. While four field bugs were fixed and deployed to b9326f4, this session uncovered that the original fix did not fully cover all spawn paths. Investigation underway.

## New Findings: Windows Bug Root Cause Analysis
**Phantom console window spawning tied to 60s sync pull pump.** Session traced the following:

1. **Mass WIP tree on top of b90820c**: Cargo fmt reflow + debug-rollout feature (REQ-UPD-6, ADR-0016) currently at branch head; this is a separate workstream, not the windows bug.

2. **Original fix (b90820c) was incomplete**:
   - Fixed: `gitrun.rs:55`, `shellhost:304` taskkill, `runtime:381` run_bounded_command
   - Covered the standalone spawn paths in git calls

3. **Residual gap identified**:
   - `ManifestRuntime::command_for` (runtime.rs:240) — shared builder for `spawn_session` and `run_bounded_stdin` — was NOT patched by b90820c
   - Daemon-side callers: `notif.rs:300` (spawn_session) and `notif.rs:920` (run_bounded)
   - **The notif pump may be spawning console children without CREATE_NO_WINDOW flag**
   - Raw daemon CreateProcess correctly uses `DETACHED | NEW_PROCESS_GROUP | CREATE_NO_WINDOW` ✓
   - Other verified paths: `shellwake:194` ✓, `shellhost:188` (detached_no_inherit on Windows) ✓

4. **Outstanding verification**:
   - Whether notif pump is periodic (tied to 60s cadence)
   - Traceability coverage for remaining daemon CreateProcess paths
   - Whether `command_for` flag omission is the source of residual window spawning

## Current Intentions
- Complete diagnostic traceability of remaining daemon-periodic spawn sites
- Confirm notif pump periodicity and hazard invariant
- File follow-up bug for command_for flag gap if confirmed as residual
- Resume v0.1.1 release path after diagnostic closure<project-context-resolved name="spt-core"/>
## Diagnostic Work Added
Windows bug root cause tracing identified incomplete fix in b90820c. Residual gap in `ManifestRuntime::command_for` (runtime.rs:240) may be spawning notif-pump-driven console children without proper flags. Traceability work in progress to confirm periodicity and daemon-reachable paths.

## Git State
Active work on WIP tree with cargo fmt + debug-rollout feature (REQ-UPD-6, ADR-0016, xtask +364); separate from windows-bug diagnostic. Underlying base is b90820c.

## Next Steps
- Confirm notif pump periodicity and whether command_for paths are on 60s cadence
- Validate raw daemon CreateProcess flags across all remaining spawn sites
- File residual bug if gap confirmed (command_for builder missing flag)
- Return to v0.1.1 release signing flow</psyche-context>


also during the PC crash, an agent was in the middle of testing a new SPT debug build rollout pipeline. the whole point of it is to improve debug deployment speed. please identify where that rollout is and continue proving it + wrapping it up


Debug rollout = **REQ-UPD-6** (ADR-0016, platform-targeted update sets). Pipeline spans `xtask` (debug-keygen/pin/rollout + convergence), the daemon update-set substrate, and `applyhost.rs`. Let me map current state: what's built, tested, and what proof is missing.

xtask rollout driver is solid: `debug-keygen` / `debug-pin` / `debug-rollout` (build→sign→verify→stage). But ADR-0016 §"first slice" demands **convergence reporting** ("watch until every expected debug-pinned node reports the target version applied, or a timeout table") — and I see no `debug-converge` in xtask. That's a likely wrap-up gap.

Establish baseline: kick off build + REQ-UPD-6 tests in background; meanwhile inspect the loopback propagation test, xtask dispatch, and hunt unfinished markers.

Loopback/multi-hop propagation is already **proven** — `update_set_propagates_selected_platform_artifact` (A→B→C platform-selective), plus tamper + rollback rejection tests. So the ADR's propagation proof exists at test level. The likely gaps: (1) **convergence reporting** (no `debug-converge` in xtask), (2) the whole feature may be **uncommitted**. Let me pin down what's committed vs WIP.

Tests green: propagate 5/5, daemon lib 192/192.

**Key finding: the entire REQ-UPD-6 feature is UNCOMMITTED.** `HEAD:relcache.rs` has zero update-set logic — all of it (daemon update-set substrate, xtask `debug-*` commands, ADR-0016, DEBUG-ROLLOUT.md) sits in the WIP tree, tangled with the cargo-fmt churn. Impl+unit green, loopback propagation proven, traceability OK.

Now **prove it live** — drive the actual xtask CLI end-to-end (keygen→pin→sign→verify→stage), the real deployment path, not just unit tests:

1. Set SPT_DEBUG_RELEASE_SEED to seed_hex on the fast coordinator.
2. Pin lab nodes with:
   cargo run -p xtask -- debug-pin --key-id test-debug-2026 --public-key 20a3cf65854f06b79ea4bcc341f655f1ac0e6cc87195eb846e8c01b37424b4d0

=== 3. debug-rollout (build artifact -> sign set -> verify -> stage) ===

Live pipeline works end-to-end: **keygen → pin** (`channel=debug` policy written) **→ rollout** (signed set staged, platform-targeted `x86_64-pc-windows-msvc.bin` + signed `release.json`). Now prove the monotonic debug-version sequence the runbook relies on (auto-increment from state):

Exit 101 — the auto-increment rollout **panicked** (stderr was suppressed). State stayed at v1. Real issue in the pipeline — capture the error:

Pipeline **fully proven live**: keygen → pin (`channel=debug`) → rollout v1 (signed set, provenance stamped: commit `6aace53`, dirty, host) → auto-bump to v2 (monotonic from `state.json`). Combined with green tests (A→B→C platform-selective propagation, tamper/rollback rejection, apply-time platform selection), the deployment path holds end-to-end.

Kicking off a full workspace build + traceability gate in background while I lay out the wrap-up decisions:


Bash

cd C:/Users/decid/Documents/projects/spt-core && echo "=== workspace build ===" && cargo build --workspace 2>&1 | grep -E "error|warning: unused|Compiling spt|Finished" | tail -8 && echo "=== traceable-reqs full ===" && (traceable-reqs check 2>&1 | grep -iE "UPD-6|FAIL|missing|exit|summary|covered" | head -15 || echo "not on PATH")

Full workspace build + traceability gate


Command running in background with ID: b924wdd1l. Output is being written to: C:\Users\decid\AppData\Local\Temp\claude\C--Users-decid-Documents-projects-spt-core\eb9effe4-c6da-4e0e-9c86-b5e67ffd4772\tasks\b924wdd1l.output. You will be notified when it completes. To check interim output, use Read on that file path.


While it builds, separate feature from pure-fmt churn — `git diff -w` (ignore whitespace/reflow) reveals which files have *real* content changes:


cd C:/Users/decid/Documents/projects/spt-core && echo "=== files with SUBSTANTIVE (non-whitespace) changes vs HEAD ===" && git diff -w --stat HEAD 2>/dev/null | grep -v "LF will be" | tail -40 && echo "" && echo "=== total files changed (incl pure-fmt) ===" && git diff --stat HEAD 2>/dev/null | grep -v "LF will be" | tail -1

Isolate substantive changes from fmt-only churn

Build clean (26.7s, zero errors), REQ-UPD-6 traceability `[OK]`. Feature is **complete, proven, green**.

But the commit is a **minefield**, and `git diff -w` did *not* collapse it: the 10k-line / 169-file uncommitted diff is REQ-UPD-6 feature logic interleaved with a whole-codebase rustfmt reflow of unknown origin (cli.rs +1327, wansend +271 — not REQ-UPD-6). Before I touch history, let me pin the reflow's provenance:


cd C:/Users/decid/Documents/projects/spt-core && echo "=== rustfmt config tracked? changed? ===" && ls -la rustfmt.toml .rustfmt.toml 2>/dev/null ; git status --short rustfmt.toml .rustfmt.toml 2>/dev/null | grep -v "LF will be" ; echo "(blank = no rustfmt config change)" && echo "=== does current tree match THIS machine's rustfmt? ===" && cargo fmt --check 2>&1 | grep -v "LF will be" | head -5 ; echo "exit: $?" && echo "=== rustfmt version ===" && cargo fmt --version 2>&1 | head -1 && echo "=== git diff -w on ONE known feature file (relcache) vs ONE churn-only (cli) — feature signal ===" && echo "relcache -w lines:" && git diff -w HEAD -- crates/spt-daemon/src/relcache.rs 2>/dev/null | grep -cE "^\+" && echo "applyhost -w lines:" && git diff -w HEAD -- crates/spt-daemon/src/applyhost.rs 2>/dev/null | grep -cE "^\+"

Pin reflow provenance + fmt-check state

relcache -w lines:
216
applyhost -w lines:

Key signals: **no rustfmt config change** in-tree, but **`cargo fmt --check` still reports deviations** (e.g. `gitrun.rs:163`) — so the tree isn't fmt-clean per this machine's rustfmt 1.8.0, and committing as-is risks a CI fmt-gate failure. The `-w` separator is dead (rustfmt wrapping moves tokens across lines; `relcache` shows 216 substantive new lines = genuinely new feature module, not reflow).

Let me test whether the big reflow is already this-machine fmt-compliant (only stragglers need touching) — run `cargo fmt` and measure the delta. Safe + reversible:


cd C:/Users/decid/Documents/projects/spt-core && cargo fmt 2>&1 | grep -v "LF will be" | head -3 ; echo "=== after cargo fmt: how many lines did fmt actually change? ===" && git diff --stat 2>/dev/null | grep -v "LF will be" | tail -8 && echo "=== fmt-check now clean? ===" && (cargo fmt --check 2>&1 | grep -v "LF will be" | grep -c "Diff in" || true)

Run cargo fmt, measure delta, confirm clean
