Doctrina Armadae Imperialis

The only legitimate channel by which the Imperial Armada enters Republic operations is Lex Prima. A Republic commander of any Branch may never request, summon, or coordinate with the Armada through any other channel. The chain is:

• The engagement reaches the doctrinal extremity at which the Armada might be needed — the cradle defence, the world's near-fall.
• The senior Republic authority appeals to the Emperor under Lex Prima.
• The Emperor decides. The decision is not reviewable.
• If the Emperor commits, the hulls arrive. They do not announce in advance; they arrive at Imperial timing.
• If the Emperor declines, the Republic continues with the regular service; no further appeal is doctrinal.

• No operational planning around Armada commitment. The plan must be executable by the regular service alone.
• No standing liaison. The Republic does not maintain liaison officers with the Adyton, does not seat Armada representatives on its staff, does not run intelligence pipelines into the Imperial chain. The two structures are deliberately disjoint.
• The appeal is rare and weighted. A High Command that appealed routinely would have collapsed the doctrinal restraint. The appeal is for the cradle defence and for nothing less.

The Forge

The Republic's regular industrial chain does not supply the Armada, does not maintain its hulls, does not refit it, does not see its pipeline. Even where the same engineering families appear, the Adyton's executions are not reproducible from regular specifications — and this is not industrial-secret doctrine but Imperial standing. The Republic does not ask. The treasury does not budget for it; the Emperor's fleet is the Emperor's account. Any Republic action that would inspect, audit or compel the Forge is doctrinally void.

The Republic counts its dead. The Armada's dead are not Reckoned in the regular Republic liturgy — binding by Imperial standing and by Republic restraint.

When the Armada participates in an engagement and its hulls or complement are lost, the Republic acknowledges the loss in formal liaison: a recorded note that Imperial assets engaged, that Imperial losses were reported by the Armada's own channel, and that the Republic does not enter these into the regular count. The Armada's Reckoning is conducted by the Armada itself, under whatever liturgy the Imperial standing prescribes.

This is doctrinally distinct from sine numero. Sine numero names the doctrinal failure when the Republic cannot count its own dead. The Armada's sealed Reckoning is not that — it is the Armada's count, held by the Armada. The Republic registers that a count occurred; the count itself is the Armada's.

The Servitor Vox, when speaking a combined-arms Reckoning, names the regular dead and acknowledges Armada participation without naming Armada dead. The doctrinal formula is:

“— and the Imperial Armada also engaged; their count is held by the Armada.”

• Its arrival is the Cascade Turn at maximum amplitude. When the Armada commits, the broken theatre often becomes survivable. The hulls bring force the regular service does not have; the engagement re-stabilises; the cradle holds. Rare, heavy, decisive.
• It does not integrate with the unified command's tactical chain. The Armada operates under its own command; the Legatus Operationis receives its signals on formal liaison but does not direct its hulls.
• Its commitment is open-ended. The Republic does not negotiate the duration. The Armada arrives; the Armada engages; the Armada withdraws when the Imperial standing prescribes.
• Its presence does not relieve the Republic of its doctrine. The regular service continues to fight; the unified command continues to coordinate; the cradle defence continues under regular doctrine. The Armada is a force in the engagement, not a force that replaces the engagement.

What the Republic infers, and does not codify

Over centuries of rare appearances the Republic has observed that the Armada's complement is sworn; that it observes restraint analogous to the Ius Gladii in its known engagements; that its commitments end at the engagement's resolution, with no recorded instance of occupation or garrison; and that its hulls return to Adyton standing afterward. These are the Republic's reading of a pattern, not the Armada's doctrine. The Emperor binds the Armada to whatever the Emperor binds it to, and the Republic accepts the result.

The Republic's war doctrine is built on transparency: the casus belli are five and named; the constraints are eight and absolute; the count is doctrinal; the Branches are accountable to the Holy Office and to governance. The Imperial Armada is none of these things from the Republic's side. Why is the asymmetry accepted?

• The Emperor is the root of the Republic. Not a head of state in the ordinary sense, but the figure on whose authority the Republic exists. To compel the Emperor to submit Imperial force to Republic doctrine would invert the foundational order. The Republic exists under the Emperor's authority; it does not legislate over the Emperor's reserved force.
• The Armada is rare. Most Republic wars are fought without it; most generations of Citizens never encounter its matériel. The asymmetry exists in the Codex but rarely in the Citizen's life.
• The Armada's restraint matches the Republic's. It has not, in any recorded engagement, acted contrary to Pro Humanitate. The Republic accepts this empirical observation as the basis for its tolerance — and the doctrine notes that this tolerance is conditional on continued Armada restraint.
• The reservation is structured to vanish in practice. The doctrinal default is the Armada is absent. A Republic that came to plan around it would have ceded its war doctrine to the Emperor's. The reservation exists; the reservation is not exercised; the asymmetry sits in the Codex without infecting Republic practice.

The Republic binds itself to the following. These are Republic-side constraints; the Armada has its own, which the Republic does not codify.

• No Lex Prima appeal except in cradle-defence extremity.
• No operational planning around Armada support.
• No standing liaison with the Forge or the Armada.
• No attempt to reproduce Adyton matériel.
• No catalogue of the Armada beyond the acknowledged Class lines.
• No inquiry into Armada standing orders.
• No regular-Reckoning treatment of Armada dead.
• No tactical integration into the unified command's chain.
• No Republic complaint or appeal regarding Armada decisions. The Emperor decides; the Republic accepts.
• No expansion of this Article's scope past acknowledgement.

The Republic's binding is a doctrinal commitment to restraint. The asymmetry survives only because the Republic chooses, by doctrine, not to attempt to resolve it.

Pro Humanitate. Semper Vigilo.
