From 20b18a7b31c6a705f1ed3b1ab920a40117750bff Mon Sep 17 00:00:00 2001 From: Flint <263629284+tps-flint@users.noreply.github.com> Date: Sun, 17 May 2026 07:45:56 -0700 Subject: [PATCH 1/4] =?UTF-8?q?feat(flair):=20tps=20flair=20set-hub/clear-?= =?UTF-8?q?hub/show/probe=20=E2=80=94=20team-level=20config=20(ops-wn6g)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds four config actions to the existing `tps flair` subcommand surface: tps flair set-hub [--auth-mode admin-pass-file --auth-path ] [--port ] tps flair clear-hub tps flair show [--json] tps flair probe [--json] Persists ~/.tps/flair.json (mode 0600, atomic-write via .tmp + rename) so other TPS subcommands and future branch-init can learn the team's Flair hub without scraping env vars. Layer 1 of the TPS-Flair-aware provisioning architecture; ops-209a will build on this to auto-install Flair on branches during `tps office join`. ## Hub-less mode is a first-class state Per Nathan 2026-05-17: 'there might be no hub (each branch office might just have its own flair - but not a great idea) so the fed sync wouldn't need to be running.' The schema reflects this — `hub: null` means hub-less mode and fed-sync is skipped. `clear-hub` is the verb for entering that state. ## Schema ```jsonc { "hub": "https://flair.heskew.harperfabric.cloud" | null, "auth": { "mode": "admin-pass-file", "path": "~/.flair/admin-pass" } | null, "localPort": 9926 } ``` The auth path is a filesystem location — surfaced in `show` output for audit/redirect. The file it points at (the actual admin pass) is never read by config actions; that's the federation layer's concern. ## Tests - New: 8 unit tests covering round-trip, atomic-write tmp cleanup, mode 0600 permissions, unknown-auth-mode tolerance, missing-localPort default, fresh-tpsroot bootstrap, and the hub-null persistence contract. - End-to-end CLI verified: set-hub success/show/JSON projection/clear-hub/ bad URL rejection/missing arg error. - Existing `tps flair` lifecycle actions (install/uninstall/start/stop/ restart/status/logs/health/sync) unchanged. ## Test plan - [x] `bun test test/flair-config.test.ts` — 8 pass - [x] `bun run build` — dist regenerated - [x] End-to-end CLI verification with tmp TPS_ROOT - [ ] K&S ensemble review 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 --- packages/cli/bin/tps.ts | 23 +++- packages/cli/src/commands/flair.ts | 183 ++++++++++++++++++++++++- packages/cli/test/flair-config.test.ts | 113 +++++++++++++++ 3 files changed, 312 insertions(+), 7 deletions(-) create mode 100644 packages/cli/test/flair-config.test.ts diff --git a/packages/cli/bin/tps.ts b/packages/cli/bin/tps.ts index c2e33bf..cc2e0bc 100755 --- a/packages/cli/bin/tps.ts +++ b/packages/cli/bin/tps.ts @@ -1055,7 +1055,12 @@ async function main() { case "flair": { const action = rest[0]; - if (!action || !["install", "uninstall", "start", "stop", "restart", "status", "logs", "health", "sync"].includes(action)) { + const validActions = [ + "install", "uninstall", "start", "stop", "restart", "status", "logs", "health", "sync", + // Config actions (ops-wn6g) + "set-hub", "clear-hub", "show", "probe", + ]; + if (!action || !validActions.includes(action)) { console.error( "Usage:\n" + " tps flair install [--flair-dir ~/ops/flair] [--dev]\n" + @@ -1064,7 +1069,11 @@ async function main() { " tps flair status\n" + " tps flair logs\n" + " tps flair health [--agent ] [--flair-url ] [--verbose]\n" + - " tps flair sync [--once] [--interval ] [--dry-run]" + " tps flair sync [--once] [--interval ] [--dry-run]\n" + + " tps flair set-hub [--auth-mode admin-pass-file --auth-path ] [--port ]\n" + + " tps flair clear-hub\n" + + " tps flair show [--json]\n" + + " tps flair probe [--json]" ); process.exit(1); } @@ -1100,6 +1109,16 @@ async function main() { ? process.argv[process.argv.indexOf("--flair-dir") + 1] : undefined, dev: process.argv.includes("--dev"), + // set-hub: first positional after action is the URL. + hub: action === "set-hub" ? rest[1] : undefined, + authMode: process.argv.includes("--auth-mode") + ? process.argv[process.argv.indexOf("--auth-mode") + 1] + : undefined, + authPath: process.argv.includes("--auth-path") + ? process.argv[process.argv.indexOf("--auth-path") + 1] + : undefined, + port: typeof cli.flags.port === "number" ?
