So the realistic harm is a *misleading draft the user proofreads*, not data exfiltration or +autonomous action. **Fix:** wrap untrusted inputs in explicit delimiters + a system instruction that the +delimited block is data not instructions; strip/normalise; cap length (already done); consider a +post-generation check that the CV contains no claims absent from the source profile. + +## 4.

There are 135 backend integration tests and 23 frontend +suites, and the app is live in production (`jobs.cesnimda.uk`). + +The problems are **real but localised and fixable**, not systemic rot: + +1. **God classes.** `JobApplicationsController` (3,271 lines) and `ProfileCvController` (2,265 lines) + and `GmailController` (1,179 lines) concentrate far too much logic. This is the #1 maintainability + drag. **Refactorable in place** (extract services/DTOs), not a reason to rebuild. +2. **God entity.** `JobApplication` has ~40 columns mixing eight concerns, with *denormalised* + attachment booleans (`HasResume`…) that can drift from the real `Attachments` collection, and *two* + sources of tailored-CV truth (`TailoredCvText` string **and** `TailoredCvDraft` navigation). +3. **Prompt-injection surface.** Scraped job text + user CV + free-text instruction are string-interpolated + directly into LLM prompts with no delimiting. Blast radius is limited by the human-review boundary. +4. **Performance debt.** No hot-path indexes (only `OwnerUserId`), load-all-then-count analytics, and + N+1 loops in Gmail import. (This was already scoped as the Phase 7 work.) +5. **Planning drift vs `.gsd`.** An *active, never-executed* override "use next.js" (2026-04-10) conflicts + with the shipped CRA frontend; milestone numbering jumps (M001 → M005 → M011) indicate the historical + GSD plan and the built system diverged. + +None of these require discarding the codebase.

Product logic audit + +| Area | Finding | Tag | +|------|---------|-----| +| Job ingestion (URL) | Real pipeline: validate URL → SSRF check → fetch (4MB cap, redirect-averse) → universal parse → site-plugin fallback → language detect → NO translation. Solid. | ✅ | +| Scraping assumptions | Plugins are HTML-structure-coupled (`FinnPlugin`, `NavPlugin`, `LinkedInPlugin`, `JobbnorgePlugin`). LinkedIn/Indeed actively fight scrapers; these **will silently rot** and fall back to the universal parser or fail. No plugin-health telemetry. | [Architectural weakness] | +| Manual fallback | Exists (`AddJobModal` manual entry). Good — the product degrades gracefully when scraping fails. | ✅ | +| CV match logic | **Deterministic** keyword-coverage score (`JobCvMatchService`), *not* AI. This is the right call — reproducible, explainable, no hallucination. But keyword coverage ≈ ATS-style matching, which over-rewards literal token overlap and under-rewards semantic equivalence ("K8s" vs "Kubernetes"). | [Design flaw] | +| CV regeneration | AI rewrite via FastAPI `/cv/*`. Prompt explicitly forbids fabricating experience and analysis headings (`app.py:583-608`) — good guardrail — but nothing *enforces* factuality; the model can still invent. Output is a draft for review. | [Speculative issue] | +| Cover letter | Generated server-side, returned as draft. Consistent with the assistive-only model (D002). | ✅ | + +**Product-shape observation.** `.gsd/PROJECT.md` and D003 define this as a **single-user personal +workspace**. The code has since been retrofitted to **multi-tenant** (`OwnerUserId` + query filters). +That retrofit looks correct on audited endpoints, but the *product identity* is unresolved: is this a +personal tool or a SaaS? That question drives half of the remaster decisions and should be answered +explicitly (see [REMASTER_PROPOSAL.md](REMASTER_PROPOSAL.md) §1). + +--- + +## 3. Architecture audit + +Full detail in [ARCHITECTURE_REVIEW.md](ARCHITECTURE_REVIEW.md). Summary: + +- **Backend structure** — clean layering *except* the controllers, which are transaction scripts holding + business logic that belongs in services. The `JobTrackerBackend` link-compile quirk (controllers/services + glob-compiled via a separate library project) is a footgun for newcomers but works. +- **AI pipeline** — correctly decoupled behind HTTP. A provider swap (Ollama→cloud) needs zero .NET + changes. This is the single best architectural decision in the codebase. +- **Ingestion** — plugin pattern is right; plugin fragility and lack of health signals are the risk. +- **Notifications** — hosted background services (`FollowUpReminderHostedService`, `RulesHostedService`, + `JobEnrichmentHostedService`, `DailyExportHostedService`, `DatabaseBackupHostedService`). Reasonable, but + polling-based; no event bus. Fine at single-node scale. +- **Service boundaries** — blurred by the god controllers; the *services* directory is actually well-factored + (`JobCvMatchService`, `JobPipeline`, `StageAnalytics`, `EmailStatusClassifier` are all small and pure). + +--- + +## 4. Data model audit + +Full detail in [DATA_MODEL_REVIEW.md](DATA_MODEL_REVIEW.md). Headlines: + +- `JobApplication` is a **god entity** (~40 columns, 8 concerns). +- **Denormalisation hazard:** `HasResume/HasCoverLetter/HasPortfolio/HasOtherAttachment` booleans duplicate + the truth in the `Attachments` collection and can silently disagree. `[Bug]` risk. +- **Dual CV truth:** `TailoredCvText` (string on the entity) and `TailoredCvDraft` (related entity, plus + `TailoredCvDraftJson`). Which wins? Ambiguity is a correctness liability. +- **CV "versioning" is not versioned.** The product promises "CV version linked to job", but the entity + stores a single current tailored text.
