Found in a pre-tag scan on 2026-08-17, reading the live daemon's own startup output.

The warning

Every boot prints:

WARN startup secret BRIDGED_WORKER_TOKEN: MISSING
     (profile 'local-direct' tokenEnv, profile 'sol' tokenEnv, profile 'terra' tokenEnv)
     — the daemon will start anyway, and this failure stays invisible until a worker actually
       needs it. Fix ${SHARED_ENV}/tools/secrets.sh and restart bridged from a LOGIN shell

All three named profiles work without it. The warning is a false alarm.

Why it fires

BRIDGED_WORKER_TOKEN appears nowhere in the config. It arrives as a default:

// BridgedConfig.java:308
tokenEnv = (tokenEnv == null || tokenEnv.isBlank()) ? "BRIDGED_WORKER_TOKEN" : tokenEnv;

requiredSecretEnvVars (Bridged.java:578-591) then demands tokenEnv from every non-subscription profile, with no filter on kind and no notion of a profile that needs no token. So any profile that simply does not set tokenEnv is reported as broken.

None of the three needs it:

  • local-direct — kind: claude-code, baseUrl: http://gx00.gw:8000, documented in the config as "direct vLLM — no auth, LAN only". ClaudeCodeLauncher.java:220 uses putIfPresent, so a missing token is skipped, not fatal.
  • sol, terra — kind: opencode. OpenCodeLauncher.java:348-349 falls back to the literal "bridged-local-noauth" when the token resolves empty, and these profiles read their own provider credentials anyway.

Why it is worth fixing rather than tolerating

The message is confidently wrong in both directions: it says the failure "stays invisible until a worker actually needs it" (no worker needs it) and tells the operator to edit secrets.sh and restart (nothing to add).

The cost is not the noise itself — it is what the noise does to the channel. CB-596 shipped a real startup warning on this exact log level today, the one that fires when the member credential policy is missing and every member inherits the whole secret store. A permanent false alarm beside it trains an operator to skim past both.

This is the mirror image of CB-593's rule: there, a deliberate choice must not look like an oversight. Here, a non-problem must not look like a failure.

The fix

Distinguish "this profile needs a token and it is missing" from "this profile needs no token".

The cleanest cut is to stop defaulting tokenEnv to a name nobody set. A profile that declares no tokenEnv is stating it needs none; that is different from one naming a variable that turns out to be unset. If the default is kept for compatibility, requiredSecretEnvVars must skip profiles that never declared it explicitly.

Acceptance criteria

  1. A profile with no tokenEnv and no auth requirement produces no startup warning.
  2. A profile that explicitly names a tokenEnv which is unset still warns, with the current wording. That case is real and CB-594 exists because of it — do not lose it.
  3. The distinction is tested both ways: explicit-and-missing warns, absent-and-unneeded does not.
  4. On this host, a boot after the fix prints no BRIDGED_WORKER_TOKEN line at all, while the WORKER_GITEA_TOKEN and AI_GATEWAY_TOKEN lines are unchanged.
  5. Consider whether kind: opencode should be in this check at all, given those profiles read their own provider credentials. Decide it explicitly and write the reason down — do not leave it implied.

Also seen, and deliberately NOT filed

WARN fleet health: detection-only (no notification sink configured)

This one reports a deliberate setting (notifications: mode: disabled), and the live config already explains it correctly — "nobody gets paged, NOT health is off". It is noisy but not misleading, and demoting it is a judgement call for whoever picks up this ticket, not a defect on its own.

Milestone

2.0. Nothing misbehaves; the fleet runs correctly on all seven profiles. This is about keeping the startup channel trustworthy.

Found in a pre-tag scan on 2026-08-17, reading the live daemon's own startup output. ## The warning Every boot prints: ``` WARN startup secret BRIDGED_WORKER_TOKEN: MISSING (profile 'local-direct' tokenEnv, profile 'sol' tokenEnv, profile 'terra' tokenEnv) — the daemon will start anyway, and this failure stays invisible until a worker actually needs it.

It arrives as a default: ```java // BridgedConfig.java:308 tokenEnv = (tokenEnv == null || tokenEnv.isBlank()) ? "BRIDGED_WORKER_TOKEN" : tokenEnv; ``` `requiredSecretEnvVars` (`Bridged.java:578-591`) then demands `tokenEnv` from every non-subscription profile, with no filter on `kind` and no notion of a profile that needs no token.

Already fixed and merged as 1c051c4, earlier today. Confirmed with git merge-base --is-ancestor 1c051c4 origin/main.

The current code on main:

  • FleetConfig.java:406 — tokenEnv = (tokenEnv == null || tokenEnv.isBlank()) ? null : tokenEnv;. An unset tokenEnv now stays null instead of being defaulted to a name nobody chose. That is the cut the ticket asked for.
  • Fleetd.java:940 — if (!profile.isSubscription() && profile.hasTokenEnv()). Only an explicitly named tokenEnv is required.
  • RequiredSecretEnvVarsTest covers both directions: profileWithoutTokenEnvDoesNotRequireTheOldDefault and explicitlyConfiguredUnsetTokenEnvWarnsWithCurrentWording.
  • Criterion 5 is answered in a comment at Fleetd.java:938-939: all kinds are checked when tokenEnv is explicit, because an explicit tokenEnv declares a required host secret whatever the backend does with its own provider credentials. The reason is written down, not implied.

The merge also fixed a crash that fell out of the change: making tokenEnv nullable broke ClaudeCodeLauncher's direct System::getenv on a null name. It now uses the superclass resolveEnv helper, and all four readers of tokenEnv were audited.

Mutation-checked, production code only, both reverted and diff -q-confirmed clean:

Mutation Compile errors Result
Remove the hasTokenEnv() filter in requiredSecretEnvVars 0 RED — profileWithoutTokenEnvDoesNotRequireTheOldDefault
Make Profile.hasTokenEnv() always return false 0 RED (2) — explicitlyConfiguredUnsetTokenEnvWarnsWithCurrentWording, aVarSharedByTwoProfilesIsReportedOnceNamingBoth

Build: 1215 tests, 0 failures, 0 compile errors.

Criterion 4 stays open until I redeploy — "a boot after the fix prints no WORKER_TOKEN line, while the other two lines are unchanged". Nobody has seen a real boot log on this jar yet. I will confirm it at the next restart and post the result here.

My own process error, recorded because it cost a worker run. I delegated this ticket without first checking it against main. It had been merged hours earlier, in this same session. The worker did the right thing — it checked, found the fix already present, verified all four criteria against the live code, mutation-tested them, and opened no PR because there was no diff. That is the correct outcome for a wasted brief, but the brief should not have existed. git log --grep on the ticket number before writing a brief is the cheap check I skipped.

Captured the before picture from the running daemon's log, so criterion 4 has something to compare against. It also turned up the strongest possible argument for this ticket, which I did not expect.

Here is the current boot, in order, from pid 45674 (old jar, before the fix is deployed):

INFO  startup secret AI_GATEWAY_TOKEN: set (profile 'local' tokenEnv, profile 'gx' tokenEnv)
INFO  startup secret WORKER_GITEA_TOKEN: set (profile 'local' gitTokenEnv, ... 7 profiles)
WARN  startup secret FLEETD_WORKER_TOKEN: MISSING (profile 'local-direct' tokenEnv,
      profile 'sol' tokenEnv, profile 'terra' tokenEnv, profile 'xf' tokenEnv)
      — ... Fix ${SHARED_ENV}/tools/secrets.sh and restart fleetd from a LOGIN shell
INFO  startup secret LAVINMQ_URI: set (broker uriEnv)
INFO  backend-exhausted classification (CB-578 stage A): off (no profile has an
      exhaustedPattern configured; profiles: [gx, local, local-direct, opus, sol,
      sonnet, terra, xf])

The variable is named FLEETD_WORKER_TOKEN now, not BRIDGED_WORKER_TOKEN — renamed with the rest of the product. Four profiles are named, not three: xf joined them since this ticket was written. None of the four sets a tokenEnv in fleetd.yaml; I checked. So the warning is exactly the false alarm described here, still firing, and now slightly wider.

The part I did not expect

Read the last line again:

backend-exhausted classification (CB-578 stage A): off

The exhaustion feature has been completely switched off on this host, and the daemon has been saying so plainly at every single boot, one line below the false alarm.

Nobody read it. I did not read it. This morning the shared OpenAI credential ran out, a member was spawned onto it anyway, and it died without starting — because no profile had an exhaustedPattern, so nothing could classify the pane line and nothing quarantined the credential. See #176 for that incident.

This ticket argued that a permanent false alarm "trains an operator to skim startup warnings". That was the right prediction, and this is the receipt: the thing that got skimmed was a correct report, sitting directly underneath the false one, saying a whole safety feature was off. The cost of the noise was not the noise.

Predicted after picture

Stating it before I redeploy, so the check cannot be fitted to the result:

  1. The FLEETD_WORKER_TOKEN: MISSING WARN disappears entirely. No line at all for that name.
  2. The AI_GATEWAY_TOKEN, WORKER_GITEA_TOKEN and LAVINMQ_URI lines are unchanged, still naming the same profiles. Those are real, explicit, and set.
  3. The classification line changes from off to a partial coverage line naming sol and terra — because I have now added the measured exhaustedPattern to both. That is a separate fix, but it lands in the same restart, and if it does not appear, the config change did not take.

I will post the real boot log against these three.

Criterion 4 measured. All three predictions confirmed. Closing.

I redeployed onto the merged jar and checked the boot log against the three predictions I posted here before the restart, so the check could not be fitted to its result.

Daemon: pid 16890, jar b0679beb7e57.

# Prediction, posted before the restart Measured
1 Zero FLEETD_WORKER_TOKEN lines in the startup log 0 lines. Confirmed.
2 The three real secret-resolution lines are unchanged Unchanged. Confirmed.
3 No other startup warning disappears with it Confirmed — the rest of the block is byte-identical.

fleet_whoami still answers primary after the restart, so the tab pin survived.

The bug this ticket was really about

The false FLEETD_WORKER_TOKEN: MISSING warning was never itself harmful — the token resolves through a different name and always did. The harm was training. It printed on every single boot, so the startup block became something to skim past.

One line below it sat this:

backend-exhausted classification (CB-578 stage A): off

CB-578's whole quarantine path had been switched off on this host for months, and I had read past it every restart. I only saw it because this ticket made me read the block properly instead of skimming it. Fixing the noise is what exposed the real defect underneath — that is worth recording as the reason this small ticket earned its keep.

That line now reads:

backend-exhausted classification (CB-578 stage A): partial (configured: [sol, terra]; ...)

after I added the measured exhaustedPattern literal to both profiles sharing the spent OpenAI credential. See #201 for the follow-on fix to how that line names its own config key.

Criteria 1–3 were already verified by the worker against live code and mutation-tested. Criterion 4 was the one only a redeploy could answer. It is answered.
