+| Field | Default | Meaning |
+|-------|---------|---------|
+| `enabled` | `true` | Master switch. Disable to restore fully static pricing |
+| `timezone` | `Asia/Shanghai` | IANA zone used for schedule matching (DeepSeek prices are Beijing-time based) |
+| `schedule` | DeepSeek peak/off-peak | `{level, windows:[{start,end}]}` list; `HH:MM`, cross-midnight windows allowed |
+| `contextThreshold` | `200000` | Token threshold for the context tier; per-model `contextThreshold` wins over the runtime tier size from `state.provider` |
+| `providers` | `{}` | Per `providerID` → `modelID` rules |
+
+Per-model rules support two forms (explicit config wins over the built-in DeepSeek default):
+
+- `multipliers`: factor applied to the static rates per schedule level (e.g. `{"offpeak": 0.5}`)
+- `levels`: absolute rates per level, e.g. `{"peak": {"input": 0.44, "output": 0.88, "cacheRead": 0.01}, "offpeak": {"input": 0.22, ...}}`. Cache rates may be written as flat `cacheRead`/`cacheWrite` (or `cache_read`/`cache_write`) or nested `cache: {"read": …, "write": …}` (both are accepted; flat wins if both present). Default unit is **USD per 1M** (same as `state.provider`). To write prices in another currency, set `"currency": "CNY"` and either make it match the display `cost.currency` (converted via `cost.rate`) or provide the per-rule `"rate"` (USD → that currency, e.g. `"rate": 1.08` for EUR). If the currency cannot be converted (no `rate`, currency ≠ display currency), a warning is logged to stderr and the values are treated as USD. `multipliers` are ratios and have no currency.
+- `contextThreshold`: per-model override of the global threshold (wins over the runtime tier size from `state.provider`).
+
+Rates shown in the sidebar switch automatically at schedule boundaries (no polling). Session cost shown is recomputed per message from its request time + context tier when dynamic rules apply (marked `≈`); otherwise OpenCode's own `msg.cost` is used. Sub-agent rows use their **session creation time** (`session.list`) for time-of-day pricing (marked `≈` on the Agents total when any child was recomputed).
+
+**Timeline dashboard** ([docs/en/timeline.md](docs/en/timeline.md)) also recomputes costs offline: it reads `~/.config/opencode/opencode.json` (JSONC-aware) for provider rates and injects `dynCost` per record (shown with `≈` and in charts/totals when it differs from the original).
+
+**Refresh official DeepSeek rates**: `bun scripts/fetch-deepseek-pricing.ts` prints a ready-to-paste `dynamicPricing.providers` snippet (CNY by default with `"currency": "CNY"`, `--usd --rate 6.77` for USD).

+## Dynamic pricing (`dynamicPricing`)
+
+Two orthogonal price dimensions resolve to the effective per-1M rates shown in the sidebar:
+
+- **Context tier**: reads the runtime cost tiers from `state.provider` (`tiers[]` / `experimentalOver200K`, normalized into the internal context tier with its own threshold); picks the tier by total context (`input + cacheRead`) vs the threshold (per-model config > runtime tier size > global > 200k). Zero-config for models like GPT-5.6.
+- **Time-of-day tier**: `schedule` (default DeepSeek peak 09:00-12:00 / 14:00-18:00 Beijing, off-peak otherwise) + per-model `multipliers` (default DeepSeek off-peak 0.5×) or absolute `levels` (level miss falls back to static rates; `enabled: false` restores fully static pricing).
+
+Lookup fallback chain (`src/dynamic-pricing/lookup.ts`): explicit `levels` → explicit `multipliers` → built-in DeepSeek default → static `state.provider` cost.
+
+- `src/dynamic-pricing/schedule.ts`: timezone-aware window matching (`Intl.DateTimeFormat`), `nextBoundaryMs` drives a `setTimeout`-based refresh in `use-cache-hit-metrics.ts` — no polling.
+- Session cost recompute (`src/dynamic-pricing/recompute.ts`): per message, `msg.time.created` selects the tier, total context (`input + cacheRead`) the context tier; `tokens.input` excludes cache, so cache reads are billed separately at `cacheReadRate`. Shown with `≈` when dynamic rules applied.
+- Sub-agents: `session.list` entries carry `time.created` (`src/session-list.ts` → `child-session-sync.ts`), so each child's cost can be recomputed at its creation time (`recomputeSubAgentCost`).
+- Timeline dashboard (`scripts/timeline-dashboard.ts`): offline recompute reads provider rates from `~/.config/opencode/opencode.json` (JSONC-aware) and injects `dynCost` per `LlmCallRecord` (shown with `≈`, counted in charts/totals).
