+## Rationale
+
+### Phase 1 — Quick wins (independent, low risk)
+
+**1. #15 — Set up Copilot instructions**
+- Already has PR #16 in draft; just needs review and merge.
+- Improves quality and speed of all subsequent agent-assisted work.
+- Zero risk to user-facing behavior.
+
+**2. #5 — Addition of history and PE – Profile page**
+- Adds 5 text boxes (CC, HPI, PMH, PE, Clinical Summary) to the Profile tab.
+- Simple schema addition (`Patient` type + Dexie migration) with no downstream
+  dependencies.
+- High value: clerks need this data ready "just in case" the attending asks
+  during rounds.
+
+**3. #18 — Add "Others" – Labs tab**
+- Adds one new lab template with 2 fields (custom label + freeform result).
+- No impact on existing templates or report formatting logic.
+- Lets users capture any non-standard lab immediately rather than waiting for a
+  dedicated template.
+
+### Phase 2 — Core workflow improvement
+
+**4. #6 — Copy/retain inputs from latest FRICHMOND entry**
+- Medium complexity: needs a "Copy from latest" button on the FRICHMOND form
+  that pre-fills all fields from the most recent entry for the same patient.
+- Independent of all other issues.
+- High daily-use impact: FRICHMOND is updated every 12 hours and most fields
+  carry over unchanged.
+
+### Phase 3 — Lab template foundations (required before reporting rework)
+
+**5. #8 — Rework Electrolytes/Renal → Blood Chemistry**
+- Renames the existing template, expands from 7 to 31+ fields, adds ULN
+  (upper limit of normal) inputs for specific analytes, and normal-value
+  range inputs for thyroid function tests.
+- **Must be completed before #12** because the Report Tab reformatting
+  specification includes Blood Chemistry–specific formatting rules
+  (ULN multiplier display, sodium delta calculations, thyroid NV ranges)
+  that depend on these new fields existing.
+
+**6. #9 — Add ABG template**
+- Adds a new structured template with auto-calculated oxygenation indices
+  (pO2/FiO2, Desired FiO2) and age-adjusted normal values.
+- Already has PR #14 in draft.
+- **Must be completed before #12** because the reporting spec includes
+  ABG-specific comparison and Desired FiO2 display rules.
+
+### Phase 4 — Reporting overhaul (depends on Phase 3)
+
+**7. #10 + #12 — Report Tab reformatting (combine into one effort)**
+- #12 is a comprehensive superset of #10; they should be merged into a
+  single implementation.
+- Very high complexity: covers 13 specification sections including
+  header standardization, lab comparison mode, ULN multiplier display,
+  sodium delta calculations, ABG Desired FiO2 display, thyroid NV
+  ranges, urinalysis comparison rules, multi-patient vitals, orders
+  filtering, and census report restructuring.
+- Depends on #8 and #9 for the Blood Chemistry and ABG field structures.
+- Existing draft PRs #11 and #13 cover basic formatting; the advanced
+  rules (Sections 5–10, 13) still need implementation.
+
+### Phase 5 — UX enhancement (independent, highest complexity)
+
+**8. #17 — Multiple photo upload**
+- Requires schema changes (grouping multiple photos under a single
+  block), new UI components (carousel viewer, batch upload, count
+  indicator), and camera integration for batch capture.
+- Fully independent of all other issues.
+- Deferred to last because it has the highest UX complexity and the
+  current single-photo workflow is functional.

+
+Issues #5, #18, #6, and #17 are fully independent and can be parallelized.
+Issues #8 and #9 are independent of each other but both block #10/#12.

+
+## Notes
+
+- **PR consolidation:** #10 and #12 cover the same reporting tab. #12's
+  spec is the authoritative source. Recommend closing #10 (and its
+  PR #11) in favor of #12 (PR #13) to avoid merge conflicts.
+- **Existing draft PRs:** #14 (ABG) and #16 (Copilot setup) appear
+  near-complete and should be reviewed/merged first for quick progress.
+- **Schema migrations:** #5 and #8 both add fields to the patient /
+  labs schema. Implementing them sequentially avoids migration version
+  conflicts.
