+## 1.4 The IF.TTT Lifecycle (Chronological, Receipt-First)
+
+The rest of this paper explains *why* IF.TTT works (pillars, protocols, infrastructure). But IF.TTT succeeds or fails in a sequence.
+
+Below is the chronological chain-of-custody path that turns a document, decision, or output into something a skeptical reader can verify without credentials.
+
+### 1.4.1 The sequence (what happens, in order)
+
+**Required steps:**
+
+1. **Capture the source** (PDF or URL) and compute a stable fingerprint (`source_sha256`).
+2. **Generate the output** (report, dossier, decision) and compute its fingerprint (`output_sha256`).
+3. **Create a trace record** (`trace_id` UUID) binding `source_sha256` ⇄ `output_sha256`.
+4. **Publish the public receipts** under stable, no-login aliases:
+   - `/static/pack/<shareId>.md` (single-link bundle)
+   - `/static/dossier/<shareId>` (+ `/download`)
+   - `/static/trace/<shareId>` (receipt page)
+   - `/static/source/<sha256>.pdf` (source mirror)
+5. **Verification** is now possible by anyone:
+   - Hash the downloaded output → compare to `Output sha256` in the trace.
+   - Hash the downloaded source → compare to `Source sha256` in the trace.
+
+**Optional step (stronger receipts):**
+
+6. **Export a triage bundle** for offline verification (downloadable `.tar.gz`):
+   - `lightweight`: ids + hashes + URLs + trace (small receipt)
+   - `standard`: + dossier + day pack (reviewable bundle)
+   - `full`: + marketing + week pack (archive/audit pack)
+7. **Verify offline** using the public verifier (`iftrace.py`) against expected SHA256.
+
+### 1.4.2 A live example (the “first bite”)
+
+If IF.TTT is real, a skeptical reader should be able to “taste it” immediately: open a receipt, download an artifact, hash it, and see the numbers match.

+Optional triage selector (bundle downloads + expected SHA256):

+
+### 1.4.3 Why this matters
+
+Most systems explain their governance. IF.TTT publishes receipts.
+
+The “trace” is not a closing paragraph. It is the start of trust: a chain-of-custody surface that exists before anyone asks for it.

 IF.TTT is not only an internal `if://` scheme. It also has a **public receipt surface** designed for external reviewers who should not need credentials to verify provenance.
 
+**Where this fits in the lifecycle:** this section is the detailed spec for steps **4–7** in §1.4 (public receipts + optional triage bundles). It is not a bolt-on; it is the external interface of the Traceable pillar.
