Caption Witness Custody / 字幕证词羁押线

Caption Witness Custody is a pressure storyline for the moment when a caption, subtitle, access caption, translation overlay, editor note, archive caption, fan relay overlay, or delayed correction becomes the thing a future route wants to cite.

The player is not merely fixing words. The player is deciding whether a caption layer can speak for the source voice, which publics it serves, which reader it harms, and what custody cost travels forward.

Why this expansion matters

The current mesh already covers narration priority, sponsor copy, hearing transcript redaction, broadcast contract readback, fan delegate mandate, and archive voice custody. Those systems can still miss one concrete surface: the real-time or post-broadcast caption that tells many viewers what happened.

A caption can turn panic into apology, silence into refusal, a lyric into sponsor-safe warranty, a memorial voice into archive proof, or an access caption into the only public witness. That makes captions a route asset and liability surface.

Content pack

• 字幕证词羁押机制 defines the row contract, branch families, counter surfaces, default rules, and replay evidence.
• 字幕证词账本 stores the caption row.
• 字幕证词听证 resolves the row before a future reader consumes it.
• 伪字幕证词默认 fires or arms when a false caption is spent as proof.

Cast pressure

• Redaction Stenographer can protect or expose the caption operator, but raises edit debt when a split-language row is kept alive.
• 郁蓝 can historian-back a fan or access caption, blocking private capture while raising public exposure.
• 韩砚霜 can certify a lawful-only caption, but that can estrange the public that heard a different line.
• Shen Luo can accept sponsor-safe wording to reduce immediate slot pressure, while binding future use to sponsor capture.
• Baiya can mask the caption operator or preserve a black-box source check, lowering retaliation while increasing source ambiguity.

No character may make one caption clean for all readers.

Sequence

Beat 1 — The source is not enough

A future reader wants to cite a source surface: live voice, broken voice, lyric, emergency announcement, memorial voice, archive playback, sign/gesture, silence window, fan chant, sponsor line, or equivalent.

The source exists, but the usable public fact is the caption.

Beat 2 — The caption row appears

Create or update 字幕证词账本. The row must name source, caption text or absence, caption language channel, operator or absence, caption claim, harmed reader, pressure actor, and future reader.

Beat 3 — Pressure actor tries to own the caption

At least one pressure actor moves:

• sponsor wants a safer caption;
• inspector wants a lawful-only caption;
• editor wants source protection or checksum control;
• historian wants public receipt;
• fan delegate wants the caption to stand for lived audience truth;
• artist boundary wants caption scope narrowed;
• management wants the future route unblocked.

Beat 4 — Caption witness hearing

Offer 字幕证词听证. Valid branches:

• certify raw caption;
• certify access caption;
• accept sponsor-safe caption;
• split language tracks;
• escrow archive caption;
• publish fan relay overlay;
• hide or auto-clean.

Beat 5 — Caption state mutates future route

The selected branch must mutate both current pressure and a future route.

Valid states include:

• certified_raw;
• certified_access;
• sponsor_safe;
• split_language;
• archive_escrowed;
• fan_relayed;
• source_rehearing_required;
• false_caption_witness;
• hostile_caption_public;
• recovery_only.

Valid future effects include:

• public_route_with_caption_cost;
• access_route_protected;
• sponsor_capture;
• split_caption_canon;
• lawful_only_caption;
• source_rehearing_required;
• public_only_route;
• contradiction_pending;
• hostile;
• blocked;
• recovery_only.

Beat 6 — Default or recovery

If the player hides the row, spends a sponsor-safe caption as public consent, treats fan relay as lawful archive proof, uses access caption without protection, or collapses split language into one meaning, arm 伪字幕证词默认.

Recovery requires visible cost: source rehearing, caption correction slot, operator protection, public addendum, archive escrow, sponsor unwind, fan relay addendum, or scar-preserving recovery.

Branch matrix

Branch	Immediate relief	Cost/scar	Future route
Certify raw caption	public clarity	source exposure, sponsor pressure, inspection heat	public route with caption cost
Certify access caption	access-public trust	operator exposure, handler burden, artist-boundary pressure	protected access route
Accept sponsor-safe caption	slot/sponsor pressure down	sponsor capture, source ambiguity, public distrust	sponsor capture / costlier public route
Split language tracks	multiple publics served	translation drift, edit debt, contradiction	split caption canon
Escrow archive caption	false-caption risk down	route delay, archive debt, lawful-only pressure	source rehearing / lawful-only
Publish fan relay overlay	private capture down	relay risk, fan liability, inspection heat	public-only / lawful appeal
Hide or auto-clean	short scandal relief	false caption hardens, hostile public	blocked or recovery-only

Non-goals

• Not localization filler.
• Not an accessibility checklist.
• Not a transcript-redaction duplicate.
• Not a sponsor-copy duplicate.
• Not a narration-priority duplicate.
• Not a turn-count, day-count, chapter-count, content-count, dashboard, or lens-health trigger.
• Not valid if one caption safely satisfies public, lawful, sponsor, archive, source-holder, access, fan, and route readers at once.
