Summary

• item 624 fixed dev_install::run to refuse claiming success on the swap's say-so alone (byte-level verify after replace_binary), but update::run -- the ordinary user-facing agentflare update self-upgrade path -- still trusted Ok(SwapOutcome::Installed) at face value.
• Extracts the shared verification (verify_installed/digest/describe_holders) out of dev_install/mod.rs into update::swap as install_verified(), which wraps replace_binary with the same disk-level check.
• Both dev_install::run and update::run now call install_verified and match on InstallOutcome/InstallError, replacing their separately-duplicated verification logic.

Test plan

• cargo fmt --check
• cargo clippy --locked --workspace --all-targets --all-features -- -D warnings -A unsafe_code -A clippy::pedantic
• cargo test --bin agentflare swap / dev_install / update:: -- all pass, including new install_verified_verifies_the_swap_update_run_performs regression test (mirrors dev_install's existing verify_installed_accepts_identical_and_rejects_any_difference, exercising the exact call update::run makes)

Summary by CodeRabbit

• Bug Fixes
  • Updates now verify that the installed application matches the downloaded version before reporting success.
  • Update failures provide clearer information when the application cannot be replaced or remains in use.
  • Windows updates that require a restart continue to be handled and reported appropriately.
• Reliability
  • Installation results are reported more accurately, distinguishing completed, deferred, replacement, and verification failures.

📝 Walkthrough

Walkthrough

The update flow now uses shared verified installation. The swap module returns typed outcomes and errors, verifies installed bytes, and reports process holders. The development-install flow removes duplicate verification and uses the shared diagnostics.

Changes

Verified Installation Flow

Layer / File(s)	Summary
Verified swap implementation src/update/swap.rs	Adds InstallOutcome, InstallError, install_verified, and verify_installed. Immediate installations require matching size and SHA-256 content. Windows-deferred installations remain unverified until later.
Holder diagnostics src/update/swap.rs	Adds describe_holders, which reports matching agentflare process IDs or a fallback message. Tests cover both cases.
Update flow migration src/update/mod.rs, src/dev_install/mod.rs	Both callers use install_verified. They handle swap and verification errors separately. The development-install module removes its local verification and holder helpers and uses shared diagnostics.

Merge Risk: 🟡 Moderate · up to e39f2

If installed-byte verification fails, the command can report that the old binary is still present even though it may already have been replaced. Correct the recovery message before merging.
