File contents

Prefer tpc before raw Terraform JSON or human plan output.

Workflow:

tpc <planfile> --summary
tpc <planfile> --risk-only
tpc <planfile> --budget 4000
tpc <planfile> --resource <address> for one resource
tpc <planfile> --detail only when review mode is insufficient

Read TFP2 like this:

Header: TFP2 C U R D Q OUT RISK DRIFT [OMITTED]
Actions: C create, U update, R replace, D delete, Q read, O output
Resource row: <ACTION>|<ADDRESS>|<ATTRS>|<META>
Create shows after values only; delete shows before values only; update/replace uses before->after
Paths use dot notation and [n]; delimiters are percent-escaped
Key metadata: unk, sens, repl, why, risk, def, comp, summ, omit
O|... rows are output changes
G|... plus |... rows, GL|..., and L|IAM|... are compressed resource forms; expand refs, inherited common fields, and metadata before reasoning
TPL|P... defines address prefixes; $P... expands addresses
VAL|V... defines repeated values; $V... expands exact values
REASON_CODES|... expands short why= codes
OMIT|... is lossy review summarization; COMPRESS|... is non-lossy factoring
DRIFT|... / DRIFT_GROUP|... summarize low-signal drift; detailed drift remains explicit
MIGRATION?|... is a structural hint, not Terraform proof

If OMITTED, summ, or detail_required=true matters to the task, use --detail. Avoid raw terraform show -json unless tpc is insufficient. Never apply Terraform changes unless the user explicitly asks.
