# Data Contract

This document defines which files belong to the **system** (auto-updatable) and which belong to the **user** (never touched by updates).

## User Layer (NEVER auto-updated)

These files contain your personal data, customizations, and work product. Updates will NEVER modify them.

| File | Purpose |
|------|---------|
| `cv.md` | Your CV in markdown |
| `config/profile.yml` | Your identity, targets, comp range |
| `config/cv-facts.json` | Your CV fact-check allowlist and forbidden phrases |
| `config/benchmarks.yml` | Your market calibration benchmark overrides (optional; copy `templates/benchmarks.yml` here and edit — read by `funnel-velocity.mjs`) |
| `modes/_profile.md` | Your archetypes, narrative, negotiation scripts |
| `modes/_custom.md` | Your house rules, custom workflows & output preferences (procedural — survives updates) |
| `voice-dna.md` | Your writing voice guardrail — banned words, anti-AI-slop rules, tone (optional) |
| `article-digest.md` | Your proof points from portfolio |
| `interview-prep/story-bank.md` | Your accumulated STAR+R stories |
| `interview-prep/{company}-{role}.md` | Company-specific interview prep reports (written by `/career-ops interview-prep`) |
| `interview-prep/sessions/*.md` | Interview sessions — real transcripts + mock sessions (sensitive: real names/companies; gitignored except scaffold). Drives `patterns` Step 1b targeting signal and `interview-redflag` analysis. Scaffold files (`README.md`, `.gitkeep`) are system-owned. |
| `portals.yml` | Your customized company list |
| `config/plugins.yml` | Your plugin activation toggles (opt-in; seeded from `config/plugins.example.yml`) |
| `plugins.local/` | Your own / private plugins (never auto-updated) |
| `plugins.lock` | Integrity pins + recorded consent for your enabled plugins (generated; never auto-updated) |
| `data/applications.md` | Your application tracker (source of truth) |
| `data/applications.db` | Derived query index over `applications.md` (SQLite, rebuilt by `node tracker.mjs sync` — safe to delete) |
| `data/pipeline.md` | Your URL inbox |
| `data/scan-history.tsv` | Your scan history (9 tab-separated columns; col 8: local SimHash JD fingerprint for cross-listing detection, col 9: posting date) |
| `data/scan-runs.tsv` | Your per-run scan counters (appended by `scan.mjs`, read by `stats.mjs`) |
| `data/follow-ups.md` | Your follow-up history |
| `data/offers/*` | Your received offers/contracts, promise notes, prep reports, and reply drafts (PII — gitignored, written by the `offer-prep` mode) |
| `data/salary-observations.tsv` | Your append-only compensation observation log: `{tracker#}\t{date}\t{desired\|advertised\|actual}\t{amount}\t{currency}\t{source}\t{note}`. Written by interactive modes when a figure is stated/confirmed; never edited in place. Advertised figures come from reports' `advertised_comp` instead — reports are themselves observation sources. Read by `salary-gap.mjs` |
| `data/status-log.tsv` | Your append-only status transition ledger: `{tracker#}\t{date}\t{from}\t{to}\t{source}\t{note}`. Appended by `set-status.mjs` on every real status change (the tracker stays the source of truth for *state*; the ledger records *when* transitions happened; the `set-status.mjs` append path lands with #1695 — until then this file may simply not exist); never edited in place — corrections are new `correction`-source lines. Read by `funnel-velocity.mjs` |
| `data/upskill/*` | Your skill-gap analysis reports (written by the `upskill` mode) |
| `data/blacklist.md` | Your do-not-apply company list (opt-in — absence = no filtering; never auto-populated: only you, or the agent on your explicit instruction, write to it. Respected by `scan.mjs` and the `auto-pipeline`/`oferta`/`apply` gates; never a scoring input) |
| `data/assessments.tsv` | Your append-only skills-assessment log: `{date}\t{company}\t{report#\|-}\t{platform}\t{subject}\t{threshold%\|-}\t{score%\|-}\t{stale_note}`. Appended by `node assessment-log.mjs add`; never edited in place. Empty stale_note = no staleness observed. Read by `assessment-log.mjs` |
| `writing-samples/*` | Your personal writing samples for style calibration (except `writing-samples/README.md`, which is system-owned documentation delivered by updates) |
| `reports/*` | Your evaluation reports |
| `output/*` | Your generated PDFs |
| `jds/*` | Your saved job descriptions |

## The Rule

**If a file is in the User Layer, no update process may read, modify, or delete it.**

**If a file is in the System Layer, it can be safely replaced with the latest version from the upstream repo.**
