+### v1.1 Custom Sound Mappings (In Progress)
+
+**Milestone Goal:** Users can customize how traffic sounds via a TOML config file — setting custom frequencies, waveform types, and their own classification rules with named sounds.
+
+- [ ] **Phase 5: Waveform Types and Bank Decoupling** - Internal refactors establishing waveform enum and injectable bank signature
+- [ ] **Phase 6: Config Package and Sound Overrides** - TOML loading, auto-discovery, partial merge, and frequency/waveform overrides wired end-to-end
+- [ ] **Phase 7: Custom Rules and Print-Config** - User-defined classification rules and --print-config UX
+
+## Phase Details
+
+### Phase 5: Waveform Types and Bank Decoupling
+**Goal**: Four waveform types are available per traffic class, and the synthesis bank accepts an injected config map instead of reading global state
+**Depends on**: Phase 4
+**Requirements**: WAVE-01, WAVE-02
+**Success Criteria** (what must be TRUE):
+  1. User can set a traffic class to square, sawtooth, or triangle waveform and hear a tonally distinct sound with no audible aliasing or buzzing artifacts
+  2. Sine waveform continues to produce the same output as v1.0 — no regression
+  3. The synthesis bank builds layers from a passed-in config map rather than a hardcoded class list
+**Plans**: TBD
+
+### Phase 6: Config Package and Sound Overrides
+**Goal**: Users can create a TOML config file to override frequency and waveform per traffic class, with auto-discovery, partial override semantics, and clear validation errors
+**Depends on**: Phase 5
+**Requirements**: CFG-01, CFG-02, CFG-03, CFG-04, CFG-05
+**Success Criteria** (what must be TRUE):
+  1. User creates a `netsynth.toml` in the working directory with a custom Hz value and the tool uses that frequency for the specified class without touching other classes
+  2. User runs the tool with no flags in a directory without a config file — it starts silently (no warning about missing config)
+  3. User passes `--config /path/to/custom.toml` and the tool uses that file; if the file does not exist, the tool exits with a clear error before capture begins
+  4. User types `frequncy = 440` in their config file and the tool exits at startup with an error naming `frequncy` as an unrecognized key
+  5. User sets waveform for one class in TOML and leaves all other classes at their defaults — the unspecified classes are unchanged
+**Plans**: TBD
+
+### Phase 7: Custom Rules and Print-Config
+**Goal**: Users can define their own traffic classification rules in TOML, assign custom sounds to them, and inspect the full effective config before capture begins
+**Depends on**: Phase 6
+**Requirements**: RULE-01, RULE-02, RULE-03, CFG-06
+**Success Criteria** (what must be TRUE):
+  1. User adds a `[[rules]]` block in TOML matching a custom port/protocol combination and hears a distinct tone for that traffic in the output MP3
+  2. User-defined rules fire before built-in protocol rules — a custom rule for port 443 overrides the default HTTPS classification for packets on that port
+  3. A user-defined class name gets its own synthesis layer automatically — no silence or missing audio for traffic matched by a custom rule
+  4. User runs `netsynth --print-config` and sees the full effective config (defaults merged with their overrides) as commented TOML, without starting a capture
+**Plans**: TBD

 ## Accumulated Context
 
 ### Decisions
 
-All decisions archived in PROJECT.md Key Decisions table and `.planning/milestones/v1.0-ROADMAP.md`.
+- [v1.1 Roadmap]: Phase 5 consolidates waveform types (WAVE-01, WAVE-02) with bank decoupling — both are internal refactors with no user-visible surface, establishing the injectable seam before config is added
+- [v1.1 Roadmap]: Research steps 5+6 (wire config + freq/waveform overrides) collapsed into Phase 6 — they share the same integration boundary (encode.RunSynthesis signature change) and are safer to land together
+- [v1.1 Roadmap]: User class name collision with built-in TrafficClass strings is an unresolved design question — decide before coding Phase 7 (treat as override vs. reject as ambiguous)
 
 ### Pending Todos
 
@@ -54,10 +62,10 @@ None.
 
 ### Blockers/Concerns
 
-None — all v1.0 blockers resolved.
+- [Phase 7 pre-work]: User-defined class names that collide with built-in class strings (e.g., `class = "HTTPS"`) require an explicit design decision before Phase 7 coding begins. Research flags this as unresolved. Options: treat as override (simplest) or reject as ambiguous. Resolve during Phase 7 planning.
