Workflow · Earliest evidence

Find the first Telegram mention inside a selected corpus

Identify the earliest matching indexed post for a phrase or topic inside selected Telegram channels, with deterministic timestamps and explicit origin limits.

Direct answer. The Ocean can search selected indexed Telegram sources for a sufficiently specific phrase or topic, order deterministic lexical matches by stored publication time, and cite the earliest evidence it finds. The answer is bounded to that corpus and wording: it does not prove the first mention across all Telegram, identify the original author, or establish that later channels copied the earlier post.

Research fit

Who this workflow is for

Investigators reconstructing when a claim entered their monitored source set who need timestamps and post links while keeping discovery coverage separate from provenance or propagation conclusions.

01

Define the claim

Use a distinctive phrase, named event, identifier, URL, or compact topic definition rather than a broad category with many unrelated matches.

02

Freeze the corpus

Select the channels whose history is relevant and record coverage gaps before interpreting an earliest result.

03

Search both ways

Combine semantic retrieval for paraphrases with deterministic lexical matches ordered oldest to newest.

04

Verify timestamps

Open the cited messages and compare stored publication times, timezone, wording, edits visible in the current post, and surrounding context.

05

Use bounded language

Write earliest matching evidence in the selected corpus, never original source or first on Telegram without independent proof.

Practical module

Earliest-mention verification log

The log records the exact claim, selected sources, matching rule, timestamp, and reasons the result cannot establish global origin.

Search propositionDistinctive phrase, entity combination, URL, or precisely described claim being traced.
Source coverageSelected indexed channels, their available history, and known unavailable or excluded sources.
Matching methodExact lexical evidence kept separate from semantically related or paraphrased candidate posts.
Earliest timestampStored publication date and timezone for the earliest verified matching post.
Evidence linkChannel, message number, excerpt, and direct permalink used for manual validation.
Conclusion wordingA bounded statement that names corpus and matching rule instead of claiming universal origin.

Analysis contract

What the calculation actually does

For meaningful query terms, Postgres selects exact text or caption matches and orders them by external_created_at ascending; semantic candidates add paraphrase context but deterministic timestamps control first-appearance claims.

Scope

The ready Telegram sources selected for the conversation and any requested date interval. The corpus boundary is part of the answer, not an implementation detail.

Measured fields

  • Matching post
  • Publication timestamp
  • Source identity
  • Exact or semantic match status
  • Permalink
  • Coverage boundary

Coverage rules

  • Earliest means earliest inside selected indexed history
  • Exact wording and semantic similarity are distinguished
  • Unindexed, private, or deleted evidence is not recoverable
  • Timestamp ordering does not establish copying
  • Every claimed appearance requires a cited post

Questions to ask

  • Which selected channel first mentioned this exact project name?
  • Find the earliest indexed post matching this claim and show later source appearances.
  • Who published this phrase earlier inside Channel A, B, or C?

First-mention research recipe

A bounded chronology method for finding earliest indexed evidence without overstating provenance or global completeness.

Copy-ready query

Within [selected channels] and [optional dates], find the earliest indexed post matching [exact phrase or carefully defined claim]. Separate exact lexical matches from semantic candidates, show timestamps, excerpts, source names, and permalinks, and state corpus gaps. Say earliest in this selected corpus, not original source or first on Telegram.

Deterministic calculation

earliest matches

Order deterministic matching SourceItems by stored external_created_at ascending within the selected corpus; use semantic hits only as separately reviewed candidates.

Inputs to set

Claim definition
A distinctive phrase, URL, identifier, or tightly bounded proposition.
Selected corpus
Channels and indexed-history coverage included in the search.
Date bounds
Optional start and exclusive end timestamps with timezone.
Match standard
Exact wording required or semantic paraphrases allowed for review.

Expected output

  • Chronological matching-post list
  • Earliest verified corpus timestamp
  • Exact-versus-semantic distinction
  • Direct evidence links
  • Coverage and provenance disclaimer

Coverage rules

  • Do not claim global Telegram completeness
  • Do not infer copying from order alone
  • Verify semantic candidates manually
  • Keep timezone and publication dates explicit
  • Record missing source history before publishing

# First-mention research recipe

A bounded chronology method for finding earliest indexed evidence without overstating provenance or global completeness.

## Calculation

- Mode: earliest_matches
- Formula: Order deterministic matching SourceItems by stored external_created_at ascending within the selected corpus; use semantic hits only as separately reviewed candidates.

## Query

Within [selected channels] and [optional dates], find the earliest indexed post matching [exact phrase or carefully defined claim]. Separate exact lexical matches from semantic candidates, show timestamps, excerpts, source names, and permalinks, and state corpus gaps. Say earliest in this selected corpus, not original source or first on Telegram.

## Inputs

- **Claim definition:** A distinctive phrase, URL, identifier, or tightly bounded proposition.
- **Selected corpus:** Channels and indexed-history coverage included in the search.
- **Date bounds:** Optional start and exclusive end timestamps with timezone.
- **Match standard:** Exact wording required or semantic paraphrases allowed for review.

## Expected output

- Chronological matching-post list
- Earliest verified corpus timestamp
- Exact-versus-semantic distinction
- Direct evidence links
- Coverage and provenance disclaimer

## Coverage checks

- [ ] Do not claim global Telegram completeness
- [ ] Do not infer copying from order alone
- [ ] Verify semantic candidates manually
- [ ] Keep timezone and publication dates explicit
- [ ] Record missing source history before publishing

Boundaries

What this does not establish

  • Unselected or unindexed channels may contain earlier evidence
  • Semantic similarity cannot prove the same claim or copying
  • Stored timestamps do not establish original authorship
  • Deleted, private, edited, or unavailable posts may be missing
  • The product has no implemented cross-source propagation graph
