fix(secrets): recover legacy backend ownership

[skevetter]

Summary

• tolerate pre-ownership sensitive entries while still rejecting invalid backend values
• prove and persist ownership only when exactly one backend contains the value
• keep ambiguous or unprobeable entries unresolved, support explicit overwrite recovery, and never delete silently
• document automatic repair for legacy secrets indexes

Validation

• go test ./pkg/secrets -count=1
• focused recovery tests for exact-one-backend, ambiguous, unprobeable, overwrite, delete, env-write, and passphrase-file cases
• git diff --check

Pre-commit and lint are being monitored in CI. This draft must not be treated as complete until both are green.

Summary by CodeRabbit

• Bug Fixes

  • Legacy secrets without recorded backend ownership no longer fail to load.
  • Ambiguous or inconclusive backend ownership remains unresolved instead of being assigned incorrectly.
  • Secret cleanup now reports probing, opening, and removal failures instead of silently ignoring them.
  • Empty backend metadata is accepted for legacy secrets.

• Documentation

  • Clarified that ownership is recorded only when backend checks are conclusive and exactly one backend contains the value.
  • Documented “Missing value” status for unresolved, unavailable, or missing secret values.

📝 Walkthrough

Walkthrough

The secrets store now treats inconclusive backend probes as unresolved ownership. It records ownership only after conclusive results identify one backend. Deletion now reports probe, open, and removal errors. Tests and documentation cover these behaviors.

Changes

Legacy ownership resolution

Layer / File(s)	Summary
Backend probing and ownership validation pkg/secrets/backend_registry.go, pkg/secrets/index.go	File probing reports conclusive absence only for os.ErrNotExist. Empty backend ownership is accepted, while unknown non-empty backends remain invalid.
Ownership resolution and removal handling pkg/secrets/local_store.go	Ownership remains unresolved when any backend probe is inconclusive. Removal probes backends before deleting values and returns probe, open, and removal errors.
Behavior validation and documentation pkg/secrets/store_internal_test.go, sites/docs-devsy-sh/content/docs/developing-in-workspaces/secrets.mdx	Tests verify unresolved ownership, failed deletion with preserved data, and direct legacy file probing. Documentation describes when ownership is recorded and when entries show Missing value.

minimal, and validate.

Inline comments:
In `@pkg/secrets/local_store.go`:
- Around line 405-409: Update removeFromProbeableBackends and its Delete flow to
preserve the index unless every applicable backend is cleaned successfully:
probe each backend, skip conclusively absent backends, return errors for
inconclusive probes or failed removals, and treat an absent value as successful
because backend.remove is idempotent. Only remove and save the index after all
cleanup succeeds.
- Line 392: Update the ownership-repair logic around provenOwner and
s.backends.Probe to assign an owner only when exactly one backend is present and
every probe is conclusive; propagate or evaluate each probe’s conclusive result
instead of ignoring it. In probeFile, mark absence conclusive only for
os.IsNotExist(err), leaving other os.Stat errors inconclusive. Adjust
TestStore_RepairsOwnershipWhenOtherBackendUnprobeable to expect unresolved
ownership and no persisted BackendFile owner.

In `@sites/docs-devsy-sh/content/docs/developing-in-workspaces/secrets.mdx`:
- Around line 320-322: Update the secret ownership documentation near the
“Missing value” description to state that this status also occurs when multiple
backends match or when backends are unavailable, not only when no backend
contains the value. Preserve the existing guidance to set the secret again or
delete it.
