Audit Packet: The Evidence Export That Defends the Study

Definition

The audit packet is Quartyl’s exportable evidence file for a proceeding — the study’s defence deliverable: the [evidence ledger] (/docs/glossary/evidence-ledger) (the immutable, append-only record of every evidence event — the captures, the snippets, the snapshots, the source), the [audit trail] (/docs/product/audit-trails/audit-trails-overview) (the study’s chronology — the state changes, the reviews, the sign-offs, the overrides, the access), and the context (the study’s parameters, the [accept-reject matrix] (/docs/glossary/accept-reject-matrix), the benchmark’s range) — packaged in one export (the ZIP, the evidence file) for the proceeding (the TPO examination, the scrutiny, the [appeal] (/docs/glossary/itat), the MAP submission). The packet is the delivery of the [evidence ledger] (/docs/glossary/evidence-ledger)’s record — the ledger is the record (append-only, the events in sequence), the packet is the delivery (the export, the file the authority / the counsel / the appeal reads). The content is the [defending the accept-reject matrix] (/docs/benchmarking/defending-accept-reject) guide’s standing list: the per-company evidence (the captures, the source passages), the decision record (the accept/reject/flag, the rationale), the override record (the [ground-truth registry] (/docs/glossary/ground-truth-registry) linkage, the ai_reason_id), the activity record (the chronology, the sign-offs), and the benchmark (the range, the comparables, the adjustments). The retention (the packet’s storage, the study’s evidence life — the [evidence repository] (/docs/product/evidence/evidence-repository) retention management) is the packet’s governance (the retention period, the purge, the [contemporaneous documentation] (/docs/glossary/contemporaneous-documentation-30day) duty the packet’s shelf life serves).

The audit packet, in one export:
  1. The evidence ledger (the immutable record — the captures, the snippets, the snapshots, the source, in sequence)
  2. The audit trail (the study’s chronology — the state changes, the reviews, the sign-offs, the overrides, the access)
  3. The context (the study’s parameters, the accept-reject matrix, the benchmark’s range)
  4. The export (the ZIP, the evidence file — for the proceeding: the TPO, the appeal, the MAP)

The element	The content
The evidence ledger	The immutable, append-only record — the captures (the screenshots, the snippets, the source extracts), the snapshots (the point-in-time data state), the source (the URL, the filing, the database record) — in sequence, with the identity and the time
The audit trail	The study’s chronology — the state changes, the reviews, the sign-offs, the overrides (the rationale, the ground-truth registry linkage), the access log — the activity record
The context	The study’s parameters, the accept-reject matrix (the per-company decisions, the reasons, the sources), the benchmark (the range, the comparables, the adjustments)
The export	The ZIP, the evidence file — for the proceeding (the TPO examination, the appeal, the MAP submission) — the retention the governance

The working read (the defending the accept-reject guide and the audit defense): the audit packet is the defence deliverable — the file the TPO, the counsel, and the appeal read as the work as it happened (the ledger’s immutability — the append-only, the sequence — the forensic property, the work not reconstructed at audit time). The [evidence ledger] (/docs/glossary/evidence-ledger) is the packet’s core (the evidence record — the captures, the snapshots, the source); the [audit trail] (/docs/product/audit-trails/audit-trails-overview) is the packet’s activity (the chronology — the state changes, the reviews, the sign-offs, the overrides); the context (the parameters, the matrix, the benchmark) is the packet’s frame (the study the evidence is for). The [ground-truth registry] (/docs/glossary/ground-truth-registry) linkage (the ai_reason_id — the AI reason, the override, the cross-reference) is the packet’s AI control evidence (the [AI controls guide] (/docs/tp-software/ai-in-transfer-pricing)’s Layer 4 — the record control, the audit trail — the AI’s runs, the per-company evidence, the human decisions, the overrides, in sequence). The retention (the evidence repository retention management — the retention period, the purge) is the packet’s governance (the [contemporaneous documentation] (/docs/glossary/contemporaneous-documentation-30day) duty the shelf life serves — the evidence available for the proceeding, the retention the duty the packet’s life).

Example

The study (the benchmarking, the screening) is examined (the TPO, the scrutiny — the proceeding). The audit packet (the ZIP, the export) carries:

The section	The content
The evidence ledger	The immutable record (the captures — the comparable’s business description, the website snippet, the URL, the date; the snapshots — the comparable’s financials, the profile, the ratios, the data state at the screening; the source — the URL, the filing, the database record) — in sequence, with the identity and the time (the actor, the timestamp, the source)
The decisions	The accept/reject/flag (the per-company decision, the AI-assisted screening outcome, the human override, the rationale) — the accept-reject matrix the decision record
The overrides	The override (where the reviewer overrode the AI’s recommendation, the new event — the override, the rationale, the identity, the time) — the ground-truth registry linkage (the ai_reason_id)
The audit trail	The chronology (the state changes, the reviews, the sign-offs, the access log) — the activity record (the audit trails module)
The context	The study’s parameters (the method, the PLI, the years, the tested party), the benchmark (the range, the comparables, the adjustments) — the frame the evidence is for

The proceeding (the TPO) reads the packet (the evidence the ledger, the activity the trail, the frame the context) — the work as it happened (the append-only, the sequence, the source) — the defending the accept-reject record, the audit defense the proceeding’s file. The retention (the [evidence repository] (/docs/product/evidence/evidence-repository) retention management — the period, the purge) governs the packet’s shelf life (the contemporaneous documentation duty, the proceeding’s availability).

FAQ

What is the difference between the audit packet and the evidence ledger? The evidence ledger is the record (the immutable, append-only record of every evidence event — the captures, the snapshots, the source, in sequence); the audit packet is the delivery (the export — the ZIP, the evidence file — that carries the ledger, plus the [audit trail] (/docs/product/audit-trails/audit-trails-overview) (the chronology) and the context (the parameters, the matrix, the benchmark), for the proceeding). The ledger is the what (the evidence, the record); the packet is the for whom (the proceeding, the delivery) — the ledger the packet’s core, the packet the ledger’s export. The [evidence ledger term] (/docs/glossary/evidence-ledger) carries the record’s immutability (the append-only, the sequence, the source); this term carries the export (the ZIP, the content, the retention).

What is in the audit packet — the content list? The packet carries three layers: the evidence (the [evidence ledger] (/docs/glossary/evidence-ledger) — the captures, the snippets, the snapshots, the source, in sequence, with the identity and the time); the activity (the [audit trail] (/docs/product/audit-trails/audit-trails-overview) — the state changes, the reviews, the sign-offs, the overrides (the rationale, the ground-truth registry linkage), the access log); and the context (the study’s parameters, the [accept-reject matrix] (/docs/glossary/accept-reject-matrix) — the per-company decisions, the reasons, the sources; the benchmark — the range, the comparables, the adjustments). The proceeding (the TPO, the appeal, the MAP) reads the three layers (the evidence, the activity, the context) — the work as it happened, the defence the packet’s delivery. The defending the accept-reject guide’s standing list is the packet’s content (the per-company evidence, the decision record, the override record, the benchmark).

What is the retention, and why does the audit packet have a shelf life? The retention is the [evidence repository] (/docs/product/evidence/evidence-repository)’s retention management — the retention period (the study’s evidence life — the period the evidence is retained, the purge the expiry), the packet’s governance. The shelf life serves the [contemporaneous documentation] (/docs/glossary/contemporaneous-documentation-30day) duty (the evidence available for the proceeding — the TPO, the appeal, the MAP — the retention the duty the packet’s availability). The retention is the packet’s governance (the period, the purge, the evidence repository management) — the evidence retained for the proceeding, the purged on the expiry, the retention the duty the packet’s life.
