How can a message preserve its sources and traces of change across three handoffs?

To let players trace a message through a port, the writer needs to preserve the original words, every version passed on, and each recipient’s understanding. During verification, compare adjacent versions sentence by sentence. Do not simply place the final rumor beside the original and ask players to guess who lied.

What someone receives is not the same as what they think they should do. “Wait for further notice” might be understood as “You don’t need to come tonight,” but until that understanding is passed to someone else, it is not the message at the next handoff.

Waiting for a Ship in Fog Harbor, used below, is a fictional teaching example. Its characters, dialogue, and records were created to demonstrate writing techniques. It is not a real user case, a tested result, or a representation of DramaFork’s product features. The example covers only three handoffs of a single message.

Port dispatcher Shen He asks the runner A-Cen to notify cargo foreman Du Qing, who then tells boatman Luo Huai. The chain runs Shen He→A-Cen→Du Qing→Luo Huai, making three handoffs. Luo Huai’s private note does not count as a fourth.

The following is the complete setup known to the writer, not a set of facts players can prove at the outset.

Shen He’s original words are: “If the fog over the west embankment still hasn’t cleared by the second watch, the cargo crew should wait in the old warehouse for my next message. Whether the fog clears or not, do not go to the north pier.”

A-Cen tells Du Qing: “The fog over the west embankment definitely won’t clear by the second watch. The cargo crew should wait in the old warehouse for Shen He’s next message. Whether the fog clears or not, do not go to the north pier.”

The note Du Qing gives Luo Huai reads: “The fog over the west embankment definitely won’t clear by the second watch. The cargo crew should wait in the old warehouse for Shen He’s next message. The north pier is closed. Whether the fog clears or not, do not go there.”

Luo Huai writes for himself: “Second watch: gather at the old warehouse; Shen He has closed the north pier.” This paper has not been passed to anyone else.

In the writer’s setup, A-Cen removes “if” and adds “definitely won’t clear,” turning a condition into a definite prediction. Changing “my” to “Shen He’s” preserves the referent. Du Qing adds the pier’s closure as a reason for the prohibition. Luo Huai interprets waiting as gathering and attributes the decision to close the pier to Shen He. The original wording is explicit: the fog condition governs only the arrangement to wait in the old warehouse. The prohibition on going to the north pier applies regardless of the fog.

Finding Shen He’s draft tells players only what was written on the paper. To check what was actually said, the example includes separately obtained statements: Shen He says the draft was read aloud word for word; before looking at the draft again, A-Cen repeats the entire original wording and confirms having heard “if” and “whether the fog clears or not” at the time. Both statements agree with the draft, supporting the claim that the initial spoken message matched it. They still do not amount to an error-free recording. If these statements are missing or disputed, changes during Shen He’s delivery or A-Cen’s reception cannot be ruled out.

Even confirming the actual original words cannot establish whether the fog cleared by the second watch or whether the north pier was closed. Conditions in the story world require separate evidence from the scene.

The table can serve as the writer’s working record or be broken into clues obtained gradually. Keep the version numbers and record supplementary information separately rather than overwriting earlier wording. Include only judgments supported by the listed materials.

The records also need an account of their origin: A-Cen delivers the message orally at the unloading area. Du Qing makes notes as he listens, reads them aloud to A-Cen for confirmation, then writes a separate note to pass on. Players must be able to find testimony about that read-back and confirmation.

On their own, Du Qing’s notes prove only what he wrote down. A-Cen’s admission, “He read them back to me, and I said they were right,” adds evidence that both confirmed that version, but still cannot reconstruct exactly what A-Cen initially said. Confirming Du Qing’s notes does not erase A-Cen’s statement that he had previously heard “if.” These two experiences must be checked separately.

For another story, you can copy this record:

Handoff number: ____; speaker→recipient: ____; sentence received at the time: ____; sentence actually passed on: ____; recipient’s understanding: ____; record and how it was obtained: ____; grounds for treating the record as matching the actual words spoken: ____; words added, removed, or replaced: ____; scope of the condition: ____; points not yet confirmed: ____.

Complete sentences preserve fidelity; the differences column makes changes easy to locate. Keeping only summaries can lose words such as “if,” “then,” and “temporarily.” Keeping only long passages of dialogue makes changes hard to find.

At the start, Luo Huai is preparing to go to the gathering at the old warehouse. Players first see his reminder, then ask: “Does the note say to gather, or is that your interpretation?” Luo Huai produces the note. Comparing them shows that the note calls for waiting for the next message, while his reminder turns that into gathering and supplies a decision-maker for the pier’s closure.

Du Qing explains: “Since we weren’t allowed to go, I assumed it was closed. I wrote that in so he wouldn’t ask again.” This is only his account of how he reasoned. It cannot prove that the pier was closed and is insufficient to establish deliberate deception.

Finally, compare Du Qing’s notes with the draft, separately checking testimony about the initial spoken message and the read-back confirmation of his notes. If those statements are credible, the possible point of omission can be narrowed to the interval spanning A-Cen’s delivery to Du Qing, Du Qing’s recording of the message, and their joint confirmation. If the evidence cannot distinguish between a word left out by the speaker and one missed by the listener, keep that range of possibilities open. If the initial spoken message is unsupported, the possible stages must also include Shen He’s delivery and A-Cen’s reception.

A verification conclusion could read: “The available materials and character statements support the following: gathering and the attribution of the pier’s closure to Shen He came from Luo Huai’s interpretation; Du Qing wrote in the closure as a reason for the prohibition. If the testimony about the initial spoken message is accepted, the conditional wording became a definite prediction during the handoff between A-Cen and Du Qing; the specific cause remains unclear. Whether the instruction to wait in the old warehouse was triggered requires checking the fog at the second watch. The prohibition on going to the north pier explicitly applies regardless of the fog.”

Then draft a clarification: “Shen He’s draft reads: ‘If the fog over the west embankment still hasn’t cleared by the second watch, the cargo crew should wait in the old warehouse for my next message. Whether the fog clears or not, do not go to the north pier.’ Separately provided statements from Shen He and A-Cen support that this wording was conveyed at the time; ‘my’ refers to Shen He. The fog condition governs only the arrangement to wait in the old warehouse. The prohibition applies regardless of the fog. Neither the pier’s closure nor a decision by Shen He to close it has been verified; this does not justify lifting the prohibition.”

The clarification must reach everyone who received an incorrect version. Players knowing the original words will not automatically change the characters’ judgments.

If numerous paper notes do not suit the story, characters can be questioned individually and their exact words preserved. But later conversations can affect recollection: two people agreeing after discussing an event does not directly count as independent corroboration. Having them give separate accounts before showing them the conflict still cannot guarantee accurate memory.

If A-Cen has already left the port and only the draft and Du Qing’s notes remain, you can locate differences between records, but cannot conclude that “if” was lost specifically when A-Cen relayed the message to Du Qing. Players can seek witnesses to the initial delivery and the read-back confirmation, or first correct misreadings already established at the end of the chain. An unreachable character need not bring the scene to a standstill.

Another failure is revealing the complete transmission table first, then having characters act mysterious. The writer’s record can be complete, but players’ materials should appear through investigative actions, with an explanation of how each was obtained.

During final review, trace each requested action, condition’s scope, reason, and attribution of a decision back to its source. Mark anything without a source as an inference or of unknown origin. Without evidence of motive, describe only the change between versions. Let players trace the differences and explain what remains impossible to establish.
