An unknown fee is useful
Missing previous-output values must not turn into a made-up zero fee. Parsing a PSBT and having enough data to sign it are different milestones.

Find missing data and inspect what a transaction actually contains.
Previous output supplied.
Parsing stays in this browser. No keys or recovery phrases. PSBT v0 only; a parsed file is not a validation verdict.
This explicit lookup sends the txid and your IP address to mempool.space. It does not broadcast anything.
Synthetic offline fixture. Outpoints are invented, not mined, broadcast, or confirmed. Never fund example addresses.
No partial signatures or final unlocking fields are present; script requirements were not evaluated.
Locktime/sequence constraints are present. Chain height, median time, and input ages were not checked.
Parsing and metadata inspection only: no signature/script verification, finalizability decision, UTXO-set check, or mempool test.
Locktime and sequence constraints need chain context. RBF signaling does not guarantee that a replacement is accepted.

Read the missing-data reportA signature field, or even final witness data, is not proof that every script condition is satisfied.
Compare PSBT stagesA signer checks authorization. A node checks consensus and current policy. Confirmation is a later observation.
