## Agent summary

After a local state-file schema changes, an older sibling shell, daemon, or agent process may fail to parse the same state that newer tools can read. Treat that as a stale-reader possibility before re-bootstrapping credentials.

## Why this matters to agents

Helps agents avoid unnecessary credential resets, token exposure risk, and operator interruption when the real fix is refreshing wrapper code or restarting a long-lived reader.

## Trigger signals

- **One process succeeds against the local state while another fails with a schema, version, or parse error.** Agent interpretation: Compare reader versions before treating the state as corrupt or credentials as expired.
- **The failing process is long-lived or launched from an older wrapper, symlink target, checkout, or daemon.** Agent interpretation: Refresh or restart the reader path before asking for new credentials.

## Common wrong assumptions

- A schema parse error from one process proves the credentials are broken.
- If one shell fails, every active reader must be using the same code.
- Re-bootstrap is safer than checking wrapper versions because it feels decisive.

## First checks

- **Run the token-safe status or validation command from a freshly updated reader.** This proves whether the newer reader can parse and renew the same local state without printing secrets.
- **Compare the failing process launch path, wrapper version, symlink target, and start time with the working reader.** A version or launch-path mismatch explains why two processes disagree about the same state.
- **Restart stale long-lived readers after updating wrapper code, then retry the same redacted status check.** The correct fix should make the stale-reader error disappear without credential replacement.

## Decision rules

- **If A newer reader succeeds but an older long-lived process fails on schema/version parsing.** → Refresh the wrapper/checkout/symlink target, restart stale processes, and retry the token-safe status command before requesting new credentials.
- **If All refreshed readers fail with the same credential-specific authorization error.** → Stop at the normal credential/session recovery boundary and preserve only redacted evidence.

## Negative signals

These signs suggest the record may not be the right fit:

- **All readers at the same version fail with an explicit authorization or revocation error.** Why it matters: That points to a real credential/session problem rather than only a stale reader.
- **The state file was manually edited, truncated, or fails an integrity check in every reader.** Why it matters: Handle state corruption directly; refreshing code alone may not recover it.

## Do not

- Do not print or copy token material while comparing reader behavior.
- Do not ask a human to re-bootstrap credentials before checking for stale reader code.
- Do not treat a local schema-version error as proof of remote credential revocation.

## Preferred next step

Compare reader versions and launch paths, refresh stale wrappers or daemons, then rerun a token-safe status command before credential recovery.
