Lab #2824: serve daemon: unit sets SWAMP_HOME, which relocates the config dir — token/oauth daemons can't find auth.json and crash-loop

Summary

swamp serve daemon enable --auth-mode token (or oauth) installs a systemd user unit that can never start. The unit sets Environment="SWAMP_HOME=~/.swamp" (added for extension loading in #2294). With SWAMP_HOME set, getSwampConfigDir() returns $SWAMP_HOME/config instead of ~/.config/swamp. The daemon therefore can't find the auth.json written by swamp auth login, requireAuthenticated fails, and systemd restarts the unit every 10s indefinitely.

daemon enable itself runs in the user's normal environment, so its own requireAuthenticated/requireScope("serve:*") check passes and it reports success.

Reproduction (Linux, systemd --user; verified on main @ fe52cda6 and on 1e41128d)

Run swamp auth login (credentials land in ~/.config/swamp/auth.json).
In a repo, run swamp serve daemon enable --user --port 19116 --auth-mode token --admins user:admin. → ✓ Daemon enabled as user service

Run journalctl --user -u swamp-serve. It repeats every ~10s:

Error: swamp serve is a team feature that requires a free swamp-club.com account.
Sign in:
  swamp auth login
...
swamp-serve.service: Main process exited, code=exited, status=1/FAILURE

Confirm the cause: SWAMP_HOME=$HOME/.swamp swamp auth whoami → Error: Not authenticated., while plain swamp auth whoami works. Running the same serve command under systemd-run --user without SWAMP_HOME starts fine.

--auth-mode none daemons are unaffected because they skip the auth gate.

Cause

serve.ts daemon enable passes env: { SWAMP_HOME: getSwampDataDir() }.
getSwampConfigDir() in src/infrastructure/persistence/paths.ts treats SWAMP_HOME as relocating the config dir to $SWAMP_HOME/config.
The data dir default (~/.swamp) and the config dir default (~/.config/swamp) are different trees, so pinning one relocates the other.

Impact

Any authenticated (token/oauth) daemon set up via serve daemon enable on Linux crash-loops. launchd may be affected the same way if the plist sets SWAMP_HOME (not verified).

Suggested direction

Have the unit pin the data dir without moving the config dir. Options:

also set XDG_CONFIG_HOME or a dedicated config-dir variable to the enabling user's resolved config dir;
or stop deriving the config dir from SWAMP_HOME when it equals the default data dir.

Add a check in daemon enable that the credentials will be readable in the unit's environment.

A nested structural swamp still waits on its run's lock when the lock holder is not a same-host ancestor (cross-host worker, --server into a non-ancestor serve)

A nested structural swamp that outlives the run that started it keeps skipping that run's lock while the holder writes

serve HA: worker enrollment on a replica that lacks the enrollment token's definition may create a second definition (unverified)

serve HA: pull a token's definition on an auth miss so a peer accepts a new token at once

Run tracker keeps some interrupted workflow rows forever: retention waits for markSettled, which several paths never call

run doctor reads every run record on each run to rebuild the run indexes

Serve audit: two sinks with the same name share one emitter cursor, so the second never receives events

Serve audit: a durable sink write that times out is retried while the first call is still pending, so the store can hold duplicate sequences

Flaky test: ModelResolver data accessors for a renamed model return the earlier id's record from findBySpec

data query --limit returns fewer live records than exist and reports limited: false when stale catalog rows fall inside the limit

data get: help example passes --run latest, which is not a recognised run id

workflow reject leaves sibling gates waiting_approval and dependents pending in a failed, retryable run

Show expired approval gates as expired, with a Cancel action in the dashboard

digitalocean codegen leaves an orphaned security_secret.ts model file after its endpoint left the spec

workflow cancel cannot cancel a suspended run whose workflow file was deleted, and cancel --all silently skips it

workflow approve racing workflow cancel loses the cancel: the run returns to suspended after cancel reported cancelled

auth whoami says the stored API key is no longer valid when auth.json only holds an env-key identity cache

Namespace advice in the slow-lock warning is wrong for a single repo on a local datastore

Method-run records left running by a dead owner are never reaped

Flaky: usecase_sync_characterization_data_test 'data gc (serve)' asserts markDirty order that varies under parallel load

Worker dispatch rebuilds the definition with Definition.create, so a legacy-named model cannot run on a worker

A cancelled workflow exits before its steps stop, leaving their method-run records at running

Nested swamp structural command in a shell step times out on its parent's per-model lock (SWAMP_LOCK_HOLDER_PID is stripped)

Auth gate blocks nested swamp in workflow shell steps when the credential is in SWAMP_API_KEY

model cancel SIGTERMs a running swamp serve process when the method run belongs to a serve-run workflow

Follow-up action retries ignore the run's abort signal and can outlast a cancel

model cancel --all on a running workflow leaves its method-run records at running, or records them failed instead of cancelled

model cancel SIGKILLs the owner 2 s after SIGTERM, before the step executor's own 3 s kill grace, so the run never records its own cancellation

workflow cancel and supersede of a suspended run leave its jobs running in the cancelled record

Tell timeouts apart from cancels in method-run records, and review the hidden 30 s fallback timer for step-called model methods

A force-exited workflow run stays running with a dead pid: resume, recover and run doctor --fix cannot clear it

A nested workflow that suspends on manual approval forwards its suspended event into the parent run's stream

workflow cancel SIGKILLs the run 2 s after SIGTERM, cutting off always/completed cleanup jobs mid-step

Warn when datastore setup keeps managedConfig but the new datastore has no config tier

Docs: run doctor --fix and workflow recover settle runs left running by a force-exited process

serve: a relative grants-dir resolves against the working directory, not the repository

workflow resume cleanup mode can run an always-gated teardown before a suspended job's approved work
