bright blue when stderr is a real terminal; NO_COLOR or a redirect/pipe
gets the bare tag (machine consumers and the e2e captures see plain
text unchanged). Failure lines stay uncolored — the host shell's red
reads correctly there.

Gravity-linux access + deploy (established 2026-06-06):

- SSH: `david@100.100.62.43` (tailscale; key auth works from HFENDULEAM). NOT brandon/decid; `tailscale ssh` fails host-key check — use plain ssh.
- Build in the DEDICATED clone `~/spt-core-deploy` — never in `~/actions-runner/_work/spt-core/spt-core`: a CI job racing a manual build there wipes target/ mid-compile (paid once: "deps/: No such file or directory" cascade).
- cargo not on non-interactive PATH: use `$HOME/.cargo/bin/cargo`.
- Install: `cp target/release/spt ~/.local/bin/spt` after `pkill -x spt`.
- Daemon restart: `setsid nohup ~/.local/bin/spt daemon > /tmp/spt-daemon.log 2>&1 < /dev/null &` — setsid mandatory pre-d4e9314 binaries (sshd HUPs the session); binaries ≥ 4aea97e self-setsid on auto-spawn but an explicit start still wants it.
- Listener re-arm: `setsid nohup ~/.local/bin/spt ready sergey > /tmp/sergey.log 2>&1 < /dev/null &`.
- HFENDULEAM side: installed binary `%LOCALAPPDATA%\spt-core\bin\spt.exe`; stop via `Stop-Process` (kills daemon), swap, any `subnet status --nodes` auto-restarts; lea listener via `Start-Process spt.exe -ArgumentList ready,lea -WindowStyle Hidden -RedirectStandardOutput $env:TEMP\lea.log`.
- After fresh daemon restart expect ~1 min before the peer's registry feed lands (post-join address seeding gap, [[spt-daemon-is-live-infra]]); NO_PERCH on a cross-machine send during that window is the known first-sync lag, not a fault.

**Why:** fleet deploys recur every milestone closeout; username + workspace-contention + setsid + first-sync facts are all non-derivable and each cost real time once.
**How to apply:** follow verbatim for any "install latest on both machines" request; bump SHAs only.

Deploy complete.

## Both machines on `d4e9314`

| | HFENDULEAM | gravity-linux |
|---|---|---|
| binary | `%LOCALAPPDATA%\spt-core\bin\spt.exe` | `~/.local/bin/spt` |
| daemon | pid 37240 | pid 2440030 (setsid — survives ssh) |
| listener | **lea** re-armed (`%TEMP%\lea.log`) | **sergey** re-armed (`/tmp/sergey.log`) |
| status | online `[1/1]` | online `[1/1]` |

**Verified:** `SENT(WAN)` both directions, live delivery confirmed in both listener logs. 09ef831e ghost rows gone.

**Two bonus fixes shipped mid-deploy** (CI green):
- `4aea97e` — unix daemon spawn now `setsid`s: found live when the auto-spawned gravity daemon died with my ssh session
- `d4e9314` — your color report: success epilogues (`SENT`, `SENT(WAN)`, `READY`, `QUEUED`…) now print **legacy-blue** on a real terminal. They were plain stderr and PowerShell paints native stderr red. Pipes/`NO_COLOR` still get bare tags, so scripts/e2e unaffected. Failures stay red — correctly. Your next `spt send` should look right.

Gravity deploy facts (david@, dedicated `~/spt-core-deploy` clone — CI raced + wiped a build in the runner workspace, never build there) saved to memory.

Expected, yes — that screenshot is **my tool-call capture**: spt's stderr went through a pipe (`2>&1`, captured), so `is_terminal()` correctly said "not a terminal" → bare tag → PowerShell painted the captured stderr line red itself. The blue only fires when *you* run `spt send` directly in your own terminal pane.

But captured contexts (like these tool panes) staying red is half the annoyance. Adding the standard `FORCE_COLOR` escape hatch so pipes can opt in:

ANSI bytes confirmed (`ESC[94m…ESC[0m`) — color path proven. Commit + deploy:


cd C:/Users/decid/Documents/projects/spt-core && git add crates/spt/src/cli.rs && git commit -m "fix(cli): FORCE_COLOR opts piped epilogues back into blue

The tty gate keeps logs/e2e captures clean, but harness tool panes pipe
stderr AND render ANSI — they got the bare tag and the host shell's red.
FORCE_COLOR (any value but 0, the common convention) overrides the gate;
NO_COLOR still wins in auto mode.

the piped output just ended up rendering garbage for the ansi bytes [Image #12]


Gravity build+swap running. While it finishes: **answer to your question — yes, expected.** That pane was my piped capture (`2>&1` into the tool) → spt correctly suppressed color for a non-terminal → PowerShell painted the raw stderr red itself. Two ways to see blue:

1. **Your own terminal:** run `spt send sergey --from lea` interactively — stderr is a real console → blue
2. **Captured panes** (like Claude tool output): new `FORCE_COLOR=1` env (just shipped, `b3b8104`) forces the blue ANSI through pipes — proven in capture: `^[[94mSENT(WAN):…^[[0m`


[Image: source: C:\Users\decid\Documents\ShareX\Screenshots\2026-06\WindowsTerminal_HpAW2JdaCj.png]


Not garbage — that was my probe doing it on purpose: `cat -v` literalizes escape bytes to prove they're emitted (`^[[94m` = the ESC byte made printable). Raw test without `cat -v`:


cd C:/Users/decid/Documents/projects/spt-core && FORCE_COLOR=1 ./target/release/spt.exe send sergey --from lea <<< "raw ansi render probe" 2>&1

FORCE_COLOR send without cat -v

How does that last line render on your screen? Two possibilities:

- **Blue text** → harness pane passes ANSI through; `FORCE_COLOR=1` works there
- **Literal `[94m…[0m` brackets** → Claude Code sanitizes ANSI in tool output before rendering; nothing spt emits can color these panes, and `FORCE_COLOR` is only useful for other ANSI-aware pipe consumers

Either way the core fix stands: in a real interactive terminal (you typing `spt send …`), stderr is a console → auto-blue, no env needed. The red you originally flagged only persists inside captured tool panes, where the red paint comes from the harness/PowerShell stderr decoration — upstream of spt.

If the brackets render literal for you, I'd leave it: interactive = blue (the actual UX surface), captures = plain tags (machine-readable), and we don't fight the harness renderer.

CAVEMAN MODE ACTIVE (full). Drop articles/filler/pleasantries/hedging. Fragments OK. Code/commits/security: write normal.


Current position: M7 closed + rig-blessed, fleet on `b3b8104`, publish-blockers cleared. Next steps, recommended order:

**1. Live elevated-spawn verification (~10 min, closes the last M7 gap)**
The de-elevation seam is unit-proven but never run elevated for real. While fleet is fresh:
- Windows: elevated PowerShell → `spt subnet status --nodes` → confirm daemon spawns *unelevated* (linked token), unelevated `spt` still connects after
- gravity: `sudo spt subnet status` → confirm `DEELEVATED:` line, daemon runs as david, no root-owned files in `~/.spt-core`

**2. Cut v0.1.1** — the fixes were *publish*-blocking; that publish is now unblocked. Release ships M7's whole surface publicly: subnet UX, guided join, `how-to`, quickstart rewrite, plus the de-elevation/eviction/color fixes. Procedure = `RELEASE-RUNBOOK.md` (signing is manual + local — needs you for the key ceremony). Probably wants the dev-freeform → main merge first.

**3. M8 planning session** — before any adapter exists (same cheapest-now logic that put M7 before adapters):
- CLI nounification (ratified shape already in DEFERRED; rule 3 = mint REQs first)
- trust-prune verb (BIGNET carries two dead 09ef831e trust rows)
- Linux elevation install model (symlink + default-account election)
- firewall registration at install · NTP-first clock · post-join address seeding · subnet attach/detach

**4. spt-claude-code scoping** — the v1 acceptance proof, own repo. Gated behind M8's nounification since that breaks the CLI surface adapters would depend on.

My pick: **1 now** (cheap, fresh fleet), then **2** if you want the release out today, else straight to **3** as a grill session. Which?


FORCE_COLOR rebuild was running (task bswbn5sny). When done: test 'FORCE_COLOR=1 spt send' captured output contains ESC[94m; commit+push the FORCE_COLOR tweak; swap HFENDULEAM installed binary; rebuild+swap gravity from the new SHA via the memory'd deploy procedure; tell user to verify blue interactively.

Live test caught a real bug — exactly what step 1 was for. `DEELEVATE_FAIL … (os error 1346)` = `ERROR_BAD_IMPERSONATION_LEVEL`: without `SeTcbPrivilege`, Windows hands back the linked token at **identification** level — you can't make a primary token from it. My linked-token path can't work for a normal elevated admin. The DEFERRED row's first suggestion ("via the unelevated *shell* token") was right — switching to the explorer/shell-window token technique. Fallback behaved as designed (loud + inherited), but that leaves your daemon elevated.

First — what id does that banner print? `46e4dee9` ≠ your node `fb29977f`. Checking:
