+#### Ledger-Based Deposit Timing
+
+Unlock times are validated and enforced using the **Soroban ledger clock** (`env.ledger().timestamp()`), not wall-clock time. Key implications:
+
+- `unlock_time` must be supplied as a Unix timestamp (seconds since the Unix epoch).
+- The contract reads `env.ledger().timestamp()` once per invocation and caches the value locally to avoid repeated host-function calls.
+- A deposit is accepted only when `unlock_time > now` (strictly future).
+- A `withdraw` succeeds only when `env.ledger().timestamp() >= unlock_time`.
+- Ledger close times on Stellar advance roughly every 5–6 seconds. For short lock durations, callers should account for this granularity when choosing `unlock_time`.
+
+Example — depositing with a 1-hour lock:
+```
+let now: u64 = env.ledger().timestamp(); // e.g. 1_700_000_000
+let one_hour = 3_600_u64;
+contract.deposit(&depositor, &token, &amount, &(now + one_hour), &0_u32);
+```
+
+The `deposit_for` function follows the same ledger-time semantics:
+```
+// payer funds the vault; depositor is the beneficiary
+contract.deposit_for(&payer, &depositor, &token, &amount, &(now + one_hour), &0_u32);
+```
+
 #### Protocol Constants
 
 - `MAX_DEPOSIT_AMOUNT`  `1_000_000_000_000_000` (10^15 token base units)

 ## Test Snapshots
 
 Running `cargo test` may generate a `contracts/time-lock-vault/test_snapshots/` directory containing XDR snapshots of contract state produced by the Soroban test environment. These are transient build artefacts, not committed regression fixtures, and are listed in `.gitignore`. Do not commit them.
+
+## Soroban-Specific Guidance
+
+### How the Test Environment Works
+
+Soroban unit tests use the `soroban-sdk` testutils feature to spin up an in-process simulated ledger. There is **no external node or network** required. The simulated environment provides a `MockHost` that emulates ledger storage, events, and auth.
+
+Key points:
+- Tests must run natively (without `--target wasm32-unknown-unknown`) so that testutils can compile.
+- The `testutils` feature is in `[dev-dependencies]` only and is never compiled into the production WASM.
+- Never run `cargo test --target wasm32-unknown-unknown` — it will fail because testutils are not available in the WASM target.
+
+### Running Tests
+
+```bash
+# Run the full test suite
+cargo test --features testutils
+
+# Run a single test with stdout
+cargo test test_deposit_success --features testutils -- --nocapture
+
+# Run tests in release mode (catches optimisation-related edge cases)
+cargo test --release --features testutils
+
+# Run all tests with output
+cargo test --features testutils -- --nocapture
+```
+
+### Writing New Tests
+
+All tests live in `contracts/time-lock-vault/src/test.rs`. Follow these conventions:
+
+1. Use `soroban_sdk::testutils::Ledger` to set the ledger timestamp before calling time-sensitive functions:
+
+```rust
+env.ledger().with_mut(|l| {
+    l.timestamp = 1_700_000_000;
+});
+```
+
+2. Advance ledger time to simulate the passage of time:
+
+```rust
+env.ledger().with_mut(|l| {
+    l.timestamp += 3_600; // advance 1 hour
+});
+```
+
+3. Assert on typed errors, not on panic messages:
+
+```rust
+let err = contract.withdraw(&depositor, &0).unwrap_err();
+assert_eq!(err, VaultError::FundsStillLocked.into());
+```
+
+4. Every new contract function or behaviour change must be accompanied by at least one positive-path and one negative-path test.
+
+### Soroban SDK Version
+
+The workspace is pinned to `soroban-sdk = "22"` in `Cargo.toml`. Do not change the SDK version in a feature PR — version bumps require a dedicated chore PR with a full audit of breaking-change behaviour.

+`Ledger deposit path` bypasses the paused contract guard
+- Priority: Critical
+- Difficulty: Advanced
+- Labels: "bug", "security", "pause"
+
+Description
+
+The current implementation of ``deposit_by_ledger` bypasses the paused contract guard` introduces a contract behavior gap that must be corrected. The ledger-based deposit path is currently missing validation checks and consistency with the timestamp-based flow. This can lead to paused contracts accepting deposits, invalid lock durations, and a mismatch between ledger state and public API queries. Affected files: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/storage.rs`, and README documentation.
+
+Expected Behavior
+
+The ledger deposit path should use the same pause and duration validation as the timestamp deposit path, exposing all ledger deposits consistently through public queries.
+
+Tasks
+
+- [ ] Inspect `deposit_by_ledger` in `contracts/time-lock-vault/src/contract.rs`.
+- [ ] Add pause-state validation for ledger deposit entry points.
+- [ ] Add minimum and maximum lock duration checks for ledger sequence deposits.

+- Priority: High
+- Difficulty: Advanced
+- Labels: "bug", "contract", "storage"
+
+Description
+
+The current implementation of ``withdraw_to` only works for time-based deposits, ignoring ledger deposits` introduces a contract behavior gap that must be corrected. The withdrawal implementation does not correctly handle deposits created by ledger-based locks. This inconsistency leaves valid ledger deposits unreachable through the public withdraw API. Affected files: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/types.rs`.
+
+Expected Behavior
+
+Withdraw actions should support ledger-based deposits and return the correct outcome for both timestamp and ledger locks.
+
+Tasks
+
+- [ ] Review `withdraw_to` logic and verify ledger deposit compatibility.
+- [ ] Add ledger deposit handling if missing.

+`Vault query` does not expose ledger-based deposits
+- Priority: High
+- Difficulty: Advanced
+- Labels: "bug", "api", "storage"
+
+Description
+
+The current implementation of ``get_vault` does not expose ledger-based deposits` introduces a contract behavior gap that must be corrected. The vault query API currently omits ledger-based deposits from its results. External clients cannot reliably inspect all active vaults, undermining transparency and off-chain indexing. Affected files: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/storage.rs`.
+
+Expected Behavior
+
+The vault query should return all active deposits regardless of whether they were created by timestamp or ledger lock semantics.
+
+Tasks
+
+- [ ] Audit vault query implementation for ledger deposit inclusion.
+- [ ] Correct query behavior to return both time-based and ledger-based deposits.
+- [ ] Add tests for query results with mixed deposit types.

+`Time remaining query` ignores ledger-based deposits and returns 0
+- Priority: High
+- Difficulty: Advanced
+- Labels: "bug", "api", "ux"
+
+Description
+
+The current implementation of ``time_remaining` ignores ledger-based deposits and returns 0` introduces a contract behavior gap that must be corrected. The time remaining calculation ignores ledger-based deposits and returns misleading values. This can cause callers to believe a deposit is unlocked when it is still locked by ledger sequence. Affected files: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/types.rs`.
+
+Expected Behavior
+
+The time remaining query should compute the correct remaining lock interval for ledger-based deposits and not return misleading zero values.
+
+Tasks
+
+- [ ] Audit time remaining calculation for ledger deposit entries.
+- [ ] Fix the logic so ledger-based deposits produce correct remaining lock values.
+- [ ] Add regression tests for ledger-derived remaining times.

+`Deposit ID enumeration` skips ledger-based deposit IDs
+- Priority: Medium
+- Difficulty: Intermediate
+- Labels: "bug", "api", "storage"
+
+Description
+
+The current implementation of ``get_deposit_ids` skips ledger-based deposit IDs` introduces a contract behavior gap that must be corrected. The deposit identifier query does not include ledger-based entries, so clients cannot enumerate every deposit. This breaks deposit discovery and any off-chain feature that relies on a complete deposit list. Affected files: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/storage.rs`.
+
+Expected Behavior
+
+Deposit ID enumeration should list every deposit, including ledger-based entries, so external indexers can discover all active vaults.
+
+Tasks
+
+- [ ] Audit deposit ID enumeration for ledger deposit entries.
+- [ ] Update `get_deposit_ids` to include all active deposits.
+- [ ] Add tests for ledger deposit ID visibility.

+- Priority: Medium
+- Difficulty: Intermediate
+- Labels: "bug", "api", "storage"
+
+Description
+
+The current implementation of ``get_vault_batch` reads only time-based deposits, not ledger-based deposits` introduces a contract behavior gap that must be corrected. The batch vault query currently omits ledger-based deposits, preventing complete client-side vault enumeration. Affected files: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/storage.rs`.
+

+- Priority: Medium
+- Difficulty: Intermediate
+- Labels: "bug", "contract", "storage"
+
+Description
+
+The current implementation of ``cancel_deposit` cannot cancel ledger-based deposits` introduces a contract behavior gap that must be corrected. The cancel flow does not support ledger-based deposits, creating an inconsistent user experience. Depositors may not be able to cancel deposits they expect to manage, exposing functional gaps in the contract logic. Affected files: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/storage.rs`.
+
+Expected Behavior
+
+Cancel deposit should support the same deposit types and allow users to cancel valid ledger-based deposits where appropriate.
+
+Tasks
+
+- [ ] Review cancel flow for ledger deposit support.
+- [ ] Extend cancel logic to handle ledger-based deposits consistently.
+- [ ] Add tests covering cancellation of ledger deposits.

+`Depositor removal` can clear an address while ledger deposits remain active
+- Priority: Medium
+- Difficulty: Intermediate
+- Labels: "bug", "storage", "consistency"
+
+Description
+
+The current implementation of ``remove_depositor` can clear an address while ledger deposits remain active` introduces a contract behavior gap that must be corrected. The depositor removal path can remove an address while ledger deposits remain active. This risks leaving orphaned deposit state and breaking retrieval APIs. Affected files: `contracts/time-lock-vault/src/storage.rs`, `contracts/time-lock-vault/src/contract.rs`.
+
+Expected Behavior
+
+Removing a depositor should not break active ledger deposits or leave orphaned state in storage.
+
+Tasks
+
+- [ ] Review depositor removal logic and ledger deposit interactions.
+- [ ] Prevent removal of a depositor with active ledger deposits or clear related state safely.
+- [ ] Add tests for depositor removal under mixed deposit conditions.

+- Labels: "bug", "validation", "contract"
+
+Description
+
+The current implementation of ``initialize` treats zero `max_lock_secs` as `LockDurationTooLong` instead of explicit invalid config` introduces a contract behavior gap that must be corrected. The initialization validation path does not distinguish invalid config from lock duration failures clearly. This makes configuration errors harder to debug and may allow invalid runtime settings. Affected files: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/types.rs`.
+
+Expected Behavior

+
+Description
+
+The current implementation of ``contract.rs` does not explain the security model for `emergency_withdraw`` introduces a contract behavior gap that must be corrected. The emergency recovery path only supports timestamp-based deposits and ignores ledger-based vault entries. That exposes a recovery gap where some deposits cannot be recovered by admin functions. Affected files: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/storage.rs`.

+Emergency recovery should cover both timestamp and ledger-based deposits so admin recovery is complete.
+
+Tasks
+
+- [ ] Review emergency withdrawal paths for ledger and timestamp deposits.

+Ledger deposit path bypasses the paused contract guard
+- Priority: Critical
+- Difficulty: Advanced
+- Labels: "bug", "security", "pause"
+
+Description
+
+The ledger deposit path in `contracts/time-lock-vault/src/contract.rs` is currently missing validation rules that other deposit methods enforce. This allows paused contracts to accept deposits and permits ledger-based lock durations that violate the configured min/max bounds. Affected modules: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/storage.rs`, and `README.md`. This gap increases the risk of inconsistent deposit state and incorrect behavior for clients that rely on ledger and timestamp lock types.

+
+The `withdraw_to` implementation in `contracts/time-lock-vault/src/contract.rs` currently only supports time-based deposits and ignores ledger-based vault entries. That means valid ledger deposits cannot be withdrawn through this public API, creating a functional gap. Affected modules: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/types.rs`. This inconsistency risks broken withdrawal behavior and poor client interoperability.
+
+Expected Behavior
+
+Withdraw-to should support both time-based and ledger-based deposits and return correct results for all active vault entries.
+
+Tasks
+
+- [ ] Review `withdraw_to` implementation in `contracts/time-lock-vault/src/contract.rs`.
+- [ ] Extend withdrawal handling to support ledger-based deposits.
+- [ ] Add tests covering withdrawal of ledger deposit entries.

+Ledger deposit path provides a sequence-based lock without cross-checking timestamp conversions
+- Priority: Low
+- Difficulty: Intermediate
+- Labels: "security", "contract", "future-proofing"
+
+Description
+
+The ledger deposit path in `contracts/time-lock-vault/src/contract.rs` is currently missing validation rules that other deposit methods enforce. This allows paused contracts to accept deposits and permits ledger-based lock durations that violate the configured min/max bounds. Affected modules: `contracts/time-lock-vault/src/contract.rs`, `contracts/time-lock-vault/src/storage.rs`, and `README.md`. This gap increases the risk of inconsistent deposit state and incorrect behavior for clients that rely on ledger and timestamp lock types.
+
+Expected Behavior
+
+The ledger deposit path should enforce pause state and correct lock-duration validation, matching the timestamp deposit flow and exposing ledger deposits consistently through public queries.
+
+Tasks
+
+- [ ] Inspect `deposit_by_ledger` in `contracts/time-lock-vault/src/contract.rs`.
+- [ ] Add pause-state validation for ledger deposit entry points.
+- [ ] Add minimum and maximum lock duration checks for ledger sequence deposits.
+- [ ] Update any API or storage helpers that expose ledger deposits.

@@ -40,3 +40,56 @@ The following are considered in-scope vulnerabilities:
 ## Disclosure Policy
 
 We follow coordinated disclosure. Please allow us reasonable time to patch before any public disclosure.
+
+### Disclosure Timeline
+
+| Step | Timeframe |
+|------|-----------|
+| Acknowledgement of your report | Within 72 hours of receipt |
+| Initial triage and severity assessment | Within 5 business days |
+| Status update to reporter | Every 7 days until resolved |
+| Patch release for Critical/High issues | Within 14 days of confirmation |
+| Patch release for Medium/Low issues | Within 60 days of confirmation |
+| Public disclosure (coordinated with reporter) | After patch is available, or after 90 days maximum |
+
+If a fix requires redeployment of the contract (because Soroban contracts are immutable), the disclosure timeline begins from when a migration path is communicated to users.
+
+## Severity Guidelines
+
+We use a four-level severity scale aligned with CVSS v3.
+
+### Critical
+
+Direct, exploitable fund loss or theft with no prerequisites.
+
+Examples:
+- Logic bug allowing an attacker to withdraw another depositor's funds
+- Auth bypass on `emergency_withdraw` sending funds to a non-depositor address
+- Re-entrancy enabling double-withdrawal of the same deposit
+
+### High
+
+Significant fund loss or lock-up that requires specific conditions or limited attacker control.
+
+Examples:
+- Depositor funds permanently locked due to a storage corruption bug
+- Admin privilege escalation enabling unauthorized `emergency_withdraw` calls
+- Incorrect penalty calculation causing material fund loss on `cancel_deposit`
+
+### Medium
+
+Contract misbehaviour that does not directly cause fund loss but degrades correctness or availability.
+
+Examples:
+- Incorrect event data emitted (wrong amount or deposit_id)
+- TTL bump logic failing to extend storage, risking entry expiry before unlock time
+- Edge-case overflow in `time_remaining` returning an incorrect value
+
+### Low / Informational
+
+Minor issues or improvements with negligible security impact.
+
+Examples:
+- Missing input validation that is harmless in practice
+- Documentation inaccuracies about contract behaviour
+- Gas/instruction inefficiencies with no exploitable consequence

+## [BUG] `deposit_by_ledger` bypasses pause state and lock-duration validation
+
+**Labels:** `bug` `security` `contract`
+**Priority:** 🔴 Critical
+**Difficulty:** Advanced
+**Tags:** `contract` `pause` `validation` `ledger`
+
+---
+
+### Description
+
+`deposit_by_ledger` in `contracts/time-lock-vault/src/contract.rs` accepts ledger-based deposits without enforcing the same pause and lock-duration rules as timestamp-based deposit methods.
+
+This creates two concrete issues:
+- a paused contract can still accept ledger-based deposits,
+- ledger-based deposits can be created with durations shorter than `MIN_LOCK_DURATION_SECS` or longer than the configured maximum.
+
+---
+
+### Reproduction Steps
+
+1. Deploy the contract and call `initialize(admin, fee_recipient, None, None)`.
+2. Call `pause(admin)`.
+3. Call `deposit_by_ledger(depositor, token, amount, current_ledger + 10, 0)`.
+4. Observe the call succeeds even though the contract is paused.
+5. Call `deposit_by_ledger(depositor, token, amount, current_ledger + 1, 0)`.
+6. Observe the call succeeds despite an effectively too-short lock period.
+
+---
+
+### Expected Behavior
+
+- `deposit_by_ledger` returns `VaultError::ContractPaused` when the contract is paused.
+- `deposit_by_ledger` rejects lock durations shorter than `MIN_LOCK_DURATION_SECS`.
+- `deposit_by_ledger` rejects lock durations longer than the configured runtime `max_lock_secs` or `MAX_LOCK_DURATION_SECS`.
+- Ledger-based deposits follow the same contract invariants as timestamp-based deposits.
+
+---
+
+### Actual Behavior
+
+- `deposit_by_ledger` does not check for pause state.
+- `deposit_by_ledger` does not validate lock duration at all.
+- The ledger deposit path can therefore bypass emergency pause and create invalid locks.
+
+---
+
+### Technical Notes
+
+- `deposit()` and `deposit_for()` both call `storage::is_paused(&env)`.
+- `deposit_by_ledger()` only checks `amount` and `penalty_bps` before transferring tokens.
+- `deposit_by_ledger()` lacks any validation of `unlock_ledger` relative to `env.ledger().sequence()` other than `unlock_ledger > current_ledger`.
+- The current public API also does not properly expose ledger deposits through `get_vault`, `time_remaining`, or `get_deposit_ids`.
+
+---
+
+### Acceptance Criteria
+
+- [ ] `deposit_by_ledger` checks `storage::is_paused(&env)` and returns `VaultError::ContractPaused` when paused.
+- [ ] `deposit_by_ledger` validates `unlock_ledger` against minimum and maximum lock durations.
+- [ ] Add unit tests for paused-state rejection and ledger lock-duration boundary cases.
+- [ ] Update documentation to state pause semantics for ledger-based deposits.
+
+---
+
+### Suggested Implementation
+
+1. Add pause validation at the start of `deposit_by_ledger()`:
+
+```rust
+if storage::is_paused(&env) {
+    return Err(VaultError::ContractPaused);
+}
+```
+
+2. Compute ledger-based lock duration:
+
+```rust
+let current_ledger = env.ledger().sequence();
+let lock_ledgers = unlock_ledger.saturating_sub(current_ledger);
+let lock_seconds = lock_ledgers.saturating_mul(LEDGER_SECONDS);
+```
+
+3. Reuse the existing time-based deposit bounds checks:
+
+```rust
+let max_lock = storage::get_max_lock_secs(&env).unwrap_or(MAX_LOCK_DURATION_SECS);
+if lock_seconds > max_lock {
+    return Err(VaultError::LockDurationTooLong);
+}
+if lock_seconds < MIN_LOCK_DURATION_SECS {
+    return Err(VaultError::LockDurationTooShort);
+}
+```
+
+4. Add regression tests for paused contracts and invalid ledger lock durations.

+# Wave Program Contribution Plan — Decentralized Time-Lock Vault
+
+## Overview
+
+This document describes how the Decentralized Time-Lock Vault participates in the Wave Program. Maintainers post scoped, well-defined issues each sprint cycle that contributors can pick up independently.
+
+---
+
+## Work Categories
+
+### 1. Bug Fixes
+Issues where contract behavior deviates from spec. Examples: edge cases in timestamp arithmetic, TTL bump not firing under certain conditions, error codes returning the wrong variant, or token transfer failures not rolling back state correctly. Each bug issue includes reproduction steps, expected vs actual behavior, and affected function names.
+
+### 2. New Features
+Scoped additions to the contract surface. Examples: multi-deposit support per address, partial withdrawals, deposit top-up, time extension on existing locks, whitelisted token lists, or a fee mechanism. Each feature issue includes a design note, the proposed function signature, and acceptance criteria.
+
+### 3. Testing
+Expanding the test suite beyond current coverage. Examples: fuzz tests for boundary amounts, property-based tests for time arithmetic, integration tests against a local Soroban network, auth-bypass attempt tests, and gas/fee benchmarks. Each test issue specifies which function or scenario to target and what assertions to add.
+
+### 4. Documentation
+Improving developer and user-facing docs. Examples: inline NatSpec-style comments, a tutorial walkthrough, architecture decision records (ADRs), a changelog, CLI usage examples, or translation of docs to other languages. Each doc issue includes the target audience and the specific gap to fill.
+
+### 5. DevOps & Tooling
+CI/CD improvements, deployment automation, and developer experience. Examples: adding a Testnet smoke-test job to CI, a contract upgrade migration script, a Makefile target for local Soroban network setup, or a release tagging workflow.
+
+### 6. Security & Auditing
+Code review tasks scoped to specific modules. Examples: reviewing auth ordering in all entry points, verifying CEI pattern compliance, checking for integer edge cases, or writing a threat model document.
